        !            74:   Add set_report_new_file and set_report_new_folder options.
        !            75:

        !            82:   Change to make mbox_shortened option work a little better with
        !            83:  discard_dup_msgids = 0.
        !            84:   Change folder_by_date option to use "From " date rather than "Date: "
        !            85:  to decide which subdirectory to use. This makes it consistent with
        !            86:  top level index page.
        !            87: 
        !            88:  Peter McCluskey (Dec 26, 2003)

        !            93:   Added a mbox_shortened option to handle mboxes that have had messages
        !            94:  deleted from the start of the mbox.
        !            95: 
        !            96:  Peter McCluskey (Dec 1, 2003)
        !            97:   Fix mismatch in <ul>, </ul> in date.html with indextable = 0.
        !            98: 
        !            99:  Peter McCluskey (Nov 17, 2003)
        !           100:   Add a check for the problem with the starting message number that was
        !           101:  partly fixed on Oct 1. Now old archives with a startmsgnum = 0 .hmrc but
        !           102:  a first message of 0001.html in this case will be treated as if startmsgnum
        !           103:  was 0.
        !           104: 
        !           105:  Peter McCluskey (Nov 15, 2003)
        !           106:   Add Portugese support from Hugo Cisneiros.
        !           107: 
        !           108:  Peter McCluskey (Oct 1, 2003)
        !           109:   Fix some problems with starting message number that caused bugs when
        !           110:   increment = 1, linkquotes = 1 and using folder_by_date.
        !           111: 
        !           112:  Peter McCluskey (Sep 11, 2003)
        !           113:   Fixes to make pcre work.
        !           114: 
        !           115:  Peter McCluskey (Sep 3, 2003)
        !           116:   Applied patches from Mike McDonald to use nowrap option in the author and
        !           117:  date columns in the index tables and get rid of all of the 'width=100%'
        !           118:  options to the tables.
        !           119: 
        !           120:  Peter McCluskey (Sep 3, 2003)
        !           121:   French language improvements from Olivier Kaloudoff.
        !           122: 
        !           123:  Peter McCluskey (Sep 1, 2003)
        !           124:   Applied patches from Mike McDonald to make spamify_replacedomain use
        !           125:  set_antispam_at, change printdates to include the dates in the table
        !           126:  version of the bydate index, and make the table use the whole screen
        !           127:  width instead of 80%. 
        !           128: 
        !           129:  Jose Kahan (Aug  18, 2003)
        !           130:   - Changed to lowercase the suffixes added to the message indexes. That is,
        !           131:     from "archive name By Date" to "archive name by date" because the
        !           132:     upper case seemed out of style as we don't have any control on what
        !           133:     is the string used for the archive's name. Did this change only for
        !           134:     the English messages as I don't know if this convention works well for
        !           135:     other languages.
        !           136: 
        !           137:  Jose Kahan (Aug  18, 2003)
        !           138:   - Made the links to the different indexes show the index of the current entry.
        !           139:     This change originated from the feedback we got on the WAI enhanced archievs.
        !           140:     People find that this small changes increases the usability of the archive.
        !           141: 
        !           142:  Jose Kahan (Aug  18, 2003)
        !           143:   - The links to the first message (aka #first) were not working in the
        !           144:     by attachment, by author, and by subject indexes.
        !           145: 
        !           146:  Peter McCluskey (Aug 16, 2003)
        !           147:   - applied fix from Jean-Charles Meyrignac to handle 0x1A in mbox.
        !           148: 
        !           149:  Jose Kahan (Aug  14, 2003)
        !           150:   - After receiving more feedback, reverted the changes done for converting the
        !           151:     displayed value of the Date: header. The reason is that users like to know
        !           152:     when they send a message. This information was getting lost because we
        !           153:     were converting the date to the local time.
        !           154:   - Made the Received on date be  shown in converted local time.
        !           155:   - Added a new configuration option, indexdateformat, so that people can
        !           156:     specify a different format for indexes than the one used elsewhere. If this
        !           157:     variable is not defined., it'll use the dateformat by default.
        !           158:   - Made the index by date compare dates independently of the value of dateformat.
        !           159: 
        !           160:  Jose Kahan (Aug  13, 2003)
        !           161:   - Made the Received on footnote line use the same date format as that used for the
        !           162:     Date: header on top of the messages.
        !           163: 
        !           164:  Jose Kahan (Aug  18, 2003)
        !           165:   - Small WAI change to the list of indexes to show the entry corresponding to 
        !           166:     the current index, but outside of a link. This comes from feedback, where 
        !           167:     people said it was less distracting to see the same index to links all 
        !           168:     the time.
        !           169: 
        !           170:  Jose Kahan (Aug  18, 2003)
        !           171:   - Add the <title> WAI enhancement that I had forgotten to do for messages.
        !           172:     The new format is: [subject] from [author] on [date] ([mailing list label]).
        !           173:     I also removed the 64 characters maximum limit check we had on the title.
        !           174:     The reason is that this is not part of the HTML specification, but rather
        !           175:     a writing style. Dominique says we shouldn't be so strict in this case. In
        !           176:     addition, just adding a \0 after 64 characters could break entity names and
        !           177:     generate invalid HTML.
        !           178: 
        !           179:  Jose Kahan (Aug  13, 2003)
        !           180:   - The mailcommand option didn't work when applied to a paragraph that had
        !           181:     a previously converted href string that includes the '@' char. I added
        !           182:     a quick hack to ConvURlsString to avoid doing the mailto: convertion if an href
        !           183:     already exists in that line. The best solution would be to do something 
        !           184:     similar to ConvURLsWithHrefs.
        !           185:     Also fixed a memory leak.
        !           186: 
        !           187:  Peter McCluskey (Aug 8, 2003)
        !           188:   - Applied haof fixes from Bernhard Reiter.
        !           189: 
        !           190:  Jose Kahan (Aug  4, 2003)
        !           191:   - As a side effect of PNK's use of an SGML entity for the @ char, the 
        !           192:     mailcommand option stopped working on all the headers except for
        !           193:     the To: one.
        !           194: 
        !           195:  Jose Kahan (Aug  1, 2003)
        !           196:   - In order to guarantee the validity of XHTML documents, changed the
        !           197:     behavior of hypermail when including customized footers. Previously,
        !           198:     when using this option, the custom markup had to include the </body>
        !           199:     and </html> end tags. As we also need to include a </div> in some
        !           200:     cases for XHTML and it's much harder to guess when to add it, I
        !           201:     made hypermail always add those three end tags as needed, regardless
        !           202:     of whether the custom footer option is being used. 
        !           203: 
        !           204:  Jose Kahan (Jul 30, 2003)
        !           205:   - After talking with Dom Hazel-Massieux, I added some extra WAI enhancements
        !           206:     to the list of indexes generated by hypermai. Specifically, the date
        !           207:     is shown in a verbose name in the title attribute of each entry and in 
        !           208:     an abbreviated version in the markup that's being displayed.
        !           209: 
        !           210:  Jose Kahan (Jul 30, 2003)
        !           211:   - When rebuilding an archive, the attachment files were not being overwritten
        !           212:     correctly. . Fixed this by adding an O_TRUNC flag.
        !           213: 
        !           214:  Jose Kahan (Jul 29, 2003)
        !           215:   - Removed a memory leak in file.c as reported by insure.
        !           216:   - The ietf-mbox option didn't work on "quoted printable" encoded attachments.

        !           223:    - When show_headers was used in print.c, the newline was not recognized
        !           224:      early enough in printheaders. A check was added to assure the newline

        !           236:   - Updated pcre library with pcre-4.3 sources. We were distributing a 
        !           237:     much older version. We were distributing version was 3.3 from 
        !           238:     August 1, 2000. 
        !           239:   - Updated FILES with the lcc files and the pcre changes.
        !           240:   - Removed the deprecated "show_hr" from the tests/test.rc file.

        !           243:   - parseurl didn't work well when an URL was quoted and enclosed inside 
        !           244:     tags. Such as:
        !           245:     <dd>some url</dd> </dd was put as part of the url.

        !           248:   - Added WAI enhancements to the list of indexes generated by hypermail.
        !           249:     To make things perfect, we would need a new configuration option to give
        !           250:     the format of the date in the list of indexes format. I hard coded it
        !           251:     for the moment as I ran out of time to do it right now. As it has to
        !           252:     use an abbreviated date format to avoid having a too big list of indexes,
        !           253:     we can' t reuse the standard set_dateformat value.
        !           254:   - Removed warnings detected thru gcc Wall.

        !           260:   - Code cleaning. Removed the deprecated code for set_showhr and

        !           264:   - Arkadiusz Miskiewicz <arekm@sse.pl> reported progerr() was being 
        !           265:     called with NULL instead of the previously constructed error message. 
        !           266:     His supplied patches were applied.

        !           269:   - Made dates in subdirectory index files reflect subdirectory date range,
        !           270:     rather than the date range for the whole archive.
        !           271:

        !           273:   - Fix print_index_header_links to print MSG_ENDING date correctly (had
        !           274:     been using 2 getdatestr() calls in one argument list).
        !           275:

        !           279:  Jose Kahan (Jun 10, 2003)
        !           280:   - Some extra WAI enhancements requested during the period of public comments:
        !           281:     Order the date index by dates, like in subjects, add <dfn> to the start and
        !           282:     end period in the indexes, change the title of "jump to first message" to
        !           283:     "jump to list of messages".
        !           284:   - The top respond link didn't take into account the msgid or subject. It was 
        !           285:     just a plain mailto. Made it work as the bottom one.
        !           286: 
        !           287:  Jose Kahan (Jun 10, 2003)
        !           288:   - Adding new messages using the -u option to an existing file sometimes 
        !           289:     resulted in warnings saying "Message-ID is missing, ignoring message 
        !           290:     with subject..." Patch idea submitted by Peter.
        !           291: 
        !           292:  Jose Kahan (Jun 10, 2003)
        !           293:   - The incremental option (-u) always started new archives with 0001, rather
        !           294:     than 0000. It will now start with 0000 as before
        !           295:     For those people who had this problem and don't want to break any links to 
        !           296:     their archives when rebuilding them, there's a new configuration option 
        !           297:     allowing you to tell from which number you want to start your archive: 
        !           298:     startmsgnum. You should only set it up once and not modify it for an 
        !           299:     existing archive or your links may break.
        !           300:     A warning message appeared systematically because the showhr, which is 
        !           301:     now deprecated, was turned on by default.
        !           302:

        !           304:   - add Italian support from Gabriele Bartolini and Marco Nenciarini.

        !           307:   - Fixed initialization of prior_subdir when dirs created out of
        !           308:     order. That fixes a case where a subdir wasn't in index files with
        !           309:     reverse_folders = 1.

        !           312:   - Add the WAI enhancements proposed in 
        !           313:     http://www.w3.org/2002/03/archives-improvements/. 
        !           314:     As a consequence of this change, the sethr and usetable configuration
        !           315:     options are deprecated. The new markup takes into account the changes
        !           316:     that those options proposed and offers them in a WAI friendly way.
        !           317:     Some code cleaning needs yet to be done to remove all the cases
        !           318:     where those rules were used. Previous code version is tagged as
        !           319:     "before-wai".
        !           320:     Fixed some invalid XHTML markup too.

        !           323:   - fix txtsuffix to not crash on null pointer.
        !           324:   - fix discard_dup_msgids to work when showprogress = 0.

        !           327:   - spam encoding from Peter Karlsson. Currently enabled via the
        !           328:     spamprotect option.

        !           330:  Jose Kahan (Apr 23, 2003)
        !           331:   - As a consequence of the XHTML convertion, unconvchars() wasn't
        !           332:     storing information into the buffer when there were no entities.
        !           333: 
        !           334:  Jose Kahan (Apr 10, 2003)
        !           335:   - Converted hypermail to XHTML. The only remaining issue concerns
        !           336:     charsets. Some mail clients don't specify a correct charset or
        !           337:     specify a charset and include characters belonging to other
        !           338:     charset spaces. The solution to detect and convert the
        !           339:     foreign charset into a Unicode entity or, for the adventurous
        !           340:     hacker, convert hypermail's output to UTF-8. For the moment, only
        !           341:     the former is implemented partially;  there is only one a winlatin1
        !           342:     (Windows CP 1252) to Unicode convertion/detection being done.
        !           343:     See string.c:convchars, unconvwinlatin1, and uconvert.h for more 
        !           344:     details.
        !           345:     The best solution will be to move to UTF-8, but this has to be planned.
        !           346:     If you have a charset issue, your XHTML document will be invalid.
        !           347:     As XHTML is backwards compatible with HTML, you can avoid this problem
        !           348:     by continuing to use the text/html MIME type.
        !           349:

        !           355:   - Corrected Initializer block for ltable[12]. Had 2 fields, but struct
        !           356:     language_entry has 3 fields.
        !           357:   - Removed unused gp variable in update_deletions().
        !           358:   - modified print_main_header() to assure title meets HTML recommendations 
        !           359:     of no longer than 64 characters. 
        !           360:   - Updated docs/hypermail.rc

        !           363:   - Fixed overwrite = 0 to avoid rewrite of many files involved in replies

        !           367:   - Fixed two bugs with deleting messages with the incremental mode. One bug
        !           368:     meant that the message body was only rewritten or removed with the
        !           369:     delete_msgnum option, not delete_older / delete_newer. The other bug
        !           370:     involved only updating the is_deleted flag in the gdbm file if the
        !           371:     message body was redone to update a MSG_IN_REPLY_TO line.

        !           377:   - Fixed problem with reverse_folders option that caused the index file
        !           378:     to leave out folders when there were some unusual mismatches between the

        !           435:   - Add -DTRIO_MINIMAL. Solves a trio compile problem in SunOS and makes
        !           436:     binary a little smaller.
        !           437:   - Strip mail.c down to minimal warning message so we don't have to worry
        !           438:     about analyzing it's security problems.
        !           439:   - Changes to get strerror, memmove from pcre when missing (e.g. on SunOS).
        !           440:     How was this working on SunOS before?
        !           441:   - Fix faulty sizeof in snprintf for MSG_ENCODING_IS_NOT_SUPPORTED.
        !           442: 
        !           443:  Kent Landfield (kent@hypermail.org) (February 12, 2003)
        !           444:   - Converted msg2archive.c to use Thomas Biege's <thomas@suse.de>
        !           445:     s_popen() instead of popen().
        !           446: 
        !           447:  Kent Landfield (kent@hypermail.org) (February 11, 2003)
        !           448:   - Modified configure.in to test for snprintf. This is needed
        !           449:     since Solaris 2.5.1 does not have snprintf.  This only affects
        !           450:     the msg2archive and mbox2hypermail in the archive directory.

        !           453:   - Modified configure to assure on Solaris that the ctype functions 
        !           454:     were used instead of the macroes. New NO_MACRO define in config.h.
        !           455:   - Added most of the patches submitted by Thomas Biege <thomas@suse.de>
        !           456:   - Cleaned up compilation commenting out unused variables with NOT_USED.
        !           457:     Need to remove them and other unnecessary code soon.
        !           458:   - Various other minor compilation issues.
        !           459:   - Corrected prototype issue in print.c
        !           460:   - Added parameter checking to archive/*.c source

        !           471:   - Hypermail 2.1.6 runs on a DEC Alpha running TRU64 when compiled
        !           472:     with GCC 2.95. It does however require the -mieee flag be set for the
        !           473:     trionan.c sources.  
        !           474:   - Modified configure.in script to support setting the the -mieee flag
        !           475:     for an Alpha TRU64 build.
        !           476:   - Modified various Makefile.in files to assure clean/clobber/distclean

        !           483:   - Fixed faulty freeing of memory that caused core dump with files_by_thread
        !           484:     option.
        !           485:   - Fixed missing function call argument with files_by_thread option. I suspect
        !           486:     this was causing some random behavior, but I only found it due to valgrind.
        !           487:   - Fix for placement of link to next msg with incremental update, usetable = 0.
        !           488:

        !           501:  Peter McCluskey (January 24, 2003)
        !           502:   - Released version 2.1.6 tar file.
        !           503:   - Fix buffer overflow when progress = 2 (triggered by long attachment
        !           504:     names). Was a security risk.
        !           505:   - Fix buffer overflow in mail (cgi) program that probably created security
        !           506:     risk if gethostbyaddr returned h_name of about 80 chars for an ip address.
        !           507:   - Disabled the functionality of the mail program and replaced it by default
        !           508:     with warning about abuse by spammers. Added warnings about use of program.
        !           509:   - Change size of boundbuffer (in parse.c) to 256, limit sscanf that fills it
        !           510:     to 255 bytes. This prevents a buffer overflow with long mime boundaries. The
        !           511:     buffer overflow didn't seemed to produce only minor problems, but it's hard
        !           512:     to rule out security risks.
        !           513:   - Add check for inline attachment name overflowing attachname buffer (like
        !           514:     the check that Jose added today for non-inlined attachments).
        !           515:   - Add check for append_filename and alts_text exceeding buffer size.
        !           516:   - Delete attachment directory of messages that are discarded due to a missing
        !           517:     or duplicate message-id.
        !           518: 
        !           519:  Jose Kahan (jose@w3.org) (January 24, 2003)
        !           520:   - Fixed a buffer overflow reported by Ulf Harnhammar from VSU security.
        !           521: 
        !           522:  Peter McCluskey (January 22, 2003)
        !           523:   - If mime message has an end boundary but no start boundary (as a buggy
        !           524:     version of Microsoft Outlook seems to create), the body is now treated
        !           525:     as a plain text message rather than discarded.
        !           526:   - Update trio code to trio version 1.9.
        !           527: 
        !           528:  Peter McCluskey (January 20, 2003)
        !           529:   - Several fixes to avoid uninitialized memory reads reported by valgrind.
        !           530: 
        !           531:  Peter McCluskey (January 18, 2003)
        !           532:   - Fix random behavior in parseurl which sometimes caused core dumps on lines
        !           533:     ending in http://, ftp://, etc.
        !           534:

        !           536:   - Apply patch from Wolfgang Spraul fixing link from subdir attachment.html to
        !           537:     index.html when defaultindex = date
        !           538: 
        !           539:  Peter McCluskey (November 26, 2002)
        !           540:   - Changed attachment naming back to what it was before Jose added
        !           541:     set_nonsequential.
        !           542:   - Changed attachment naming so that files are stored using the names
        !           543:     provided without any %d- prepended whenever that doesn't cause conflicts.
        !           544:

        !           546:   - Made some updates to the docs.  Still need to update the
        !           547:     docs to include writehaof, nonsequential, msgsperfolder and
        !           548:     assure other config file directives are listed and current.

        !           555:   - Made the  "_at_" antispam bit configurable by config file, using
        !           556:       antispam_at = __somestring__  (does not have to have __ in it)
        !           557:     Anything hardcoded by default, can be figured out and used by 
        !           558:     spammers.  Particularly something like "_at_".

        !           562:   - URL generation was broken when a URL had a '@' char and hypermail
        !           563:     was using the mailcommand option. parseemail() didn't take this
        !           564:     case into account yet (there's just an empty statement). I added a
        !           565:     quick patch to convert the '@' into an HTML entity when doing the
        !           566:     convertion inside a URL. The change is in translateurl().

        !           569:   - In order to avoid hashed filename collisions, the filename
        !           570:     is now built with a hash of the msgid concatenated to the
        !           571:     Epoch seconds of the From date. This gives a total of
        !           572:     16 characters (all data is represented in hex). Only messages
        !           573:     that have the same msgid and that arrive in the same second
        !           574:     will have a collision.
        !           575:     I also compiled with the Warning flags and removed some

        !           579:   - The access righs of the msgindex file (for the hashed filenames)
        !           580:     were not being set at all.

        !           583:   - The non-sequential msgid mode didn't work when updating the
        !           584:     archives by one message. Fixed a confusion in the generation of
        !           585:     the msgindex file.

        !           589:     (what a difference does reading the manual make).

        !           592:   - Fix threading bug with incremental update and spamprotect_id = 1,

        !           597:     FILES section. Somehow, without this file, it was impossible to
        !           598:     compile the file generated thru a make tgz. The same kind of
        !           599:     file already existed in the pcre and fnv directories.
        !           600:     Added a rule to pass the FNV optional CFLAGS from the 
        !           601:     ~/hypermail/Makefile file, so that you can do a make from the top-level

        !           606:     tests).
        !           607:   - Fixed the make tgz rule (how long was it since it was last used?)

        !           610:   - Added a new option to compute the archived filenames using an fnv hash
        !           611:     of the msgid + received From date. The resulting filename is 8 bytes long
        !           612:     (a space of 2^32 bits) + the extension. You can eventually change it to
        !           613:     16 bytes if this is too short. Just look at the code. 
        !           614:     The advantage of this is that you can add and remove items from the
        !           615:     archive and not worry anymore about broken links if the sequence
        !           616:     changes (e.g., if you are rebuilding an archive). To activate this
        !           617:     option, you need to do a ./ configure --enable-libfnv, then 
        !           618:     recompile hypermail. The name of the new  option is nonsequential
        !           619:     (lack of imagination!).

        !           632:   - Fix mdecodeRFC2047 to decode headers of any length (removing 128 byte limit).
        !           633:   - Add classes to default stylesheet to set colors of headers, standard links,
        !           634:     and of quoted text according to quote nesting depth.

        !          1062:        where the quote originated. It also improves the threads index file
        !          1063:        by more accurately matching messages with replies.
        !          1064:     - searchbackmsgnum: with linkquotes and -u, speeds up processing, with
        !          1065:        some risk that linkquotes won't find all links it should.
        !          1066:     - link_to_replies: generate links from original quoted text to the

        !          1076:    * replymsg_command - used for sending a reply to the list; if not specified,
        !          1077:      is set to the value in mailcommand for compatibility with old .hmrc's

        !          1090:   external site... but I think it is an easy way to handle this problem)
        !          1091:  - add NONE as value for set_mailcommand, so "New Message" will not be shown
        !          1092:  - improve handling of inline attachments after signature.
        !          1093:  - prevent "(no email)" in emailaddr from becoming mailto.

        !          1104:    were not touched.  I'm going to leave those for their respective

        !          1108:  - Added 'spamprotect' as a new flag. It replaces @-letters with "_at_" to
        !          1109:    confuse spam-email-robots a bit.
        !          1110: 
        !          1111:  - Found a terrible bug when an URL contains a @-letter, since it'll first
        !          1112:    become <href>-tagged and then <mailto>-converted... :-/
        !          1113: 
        !          1114:  - Added https:// as a recognized URL type (deja-vu, didn't I do this before?)
        !          1115:

        !          1130: 
        !          1131:  - The quoted printable decoding didn't take into account the

        !          1133:

        !          1135: 
        !          1136:  - Removed an invalid </A> tag when using tables.
        !          1137: 
        !          1138:  - When using the showhtml option, invalid HTML was generated in the

        !          1140:  
        !          1141: - Stopped the generation of a Mailto on msgid's.
        !          1142:  
        !          1143:  - Rearranged the format of the index and messages when not using
        !          1144:    tables. My aim was to make the format more symetrical.
        !          1145: 
        !          1146:  - Added a new item, "Mail actions",  in the control menu. This item
        !          1147:    is only active when using the mailcommand and hmail options, and
        !          1148:    when the tables are turned off. This option duplicates the one found in

        !          1150: 
        !          1151:  - Added two new options for linking external stylesheets to the index 
        !          1152:    and the messages, respectively: icss_url, mcss_url. The link is added
        !          1153:    as a META element in the header.
        !          1154: 
        !          1155:  - The default value of the mailcommand mailto: had some typos: non
        !          1156:    escaped chars, use of reply-to instead of in-reply-to.
        !          1157:  
        !          1158:  - Two protections were missing to avoid having empty HREFs when the

        !          1160:    any given value.

                   1172:    (Peter C. McCluskey) submitted a patch that fixes them as well

                   1176: 
                   1177:  - Added hoaf-28 python index generator written and contributed
                   1178:    by Bernhard Reiter <bernhard@climate2.geog.uwm.edu> to the basline.
                   1179: 
                   1180:  - Added ls2mail script written by David Kilzer <ddkilzer@ti.com>

                   1182:

                   1190: 
                   1191:  - Corrected a parsing error in parsemail when dealing with
                   1192:    attachments.  If the filename was "quoted" things worked
                   1193:    properly. If the filename was not quoted then the name 
                   1194:    of the attachment was dropping the first letter of the
                   1195:    filename and adding '_' to the end. 
                   1196: 
                   1197:  - Corrected a conditional statement that was limiting storage
                   1198:    of 'inline' types to only recording inline types that were
                   1199:    of type image/.
                   1200: 
                   1201:  - Changed strstr usage when searching MIME headers to
                   1202:    use strcasestr instead as the case sensitivity was
                   1203:    getting in the way.

                   1215:    rather got added to them.  This was corrected for list usage. If
                   1216:    a list value is set in the .hmrc file, it should completely replace
                   1217:    the default values.  This need only occur on the first occurance
                   1218:    after the builtin initialization.
                   1219: 
                   1220:  - Jeff Katcher pointed out 'At the bottom of index.html and date.html, 
                   1221:    "Last message date:" is output twice.  It's only present once on the 
                   1222:    author and subject pages.'  This has been corrected so it is only
                   1223:    printed once.

                   1226: 
                   1227:  - A typo in setup.c:PreConfig gave problems (memory overwrite) when 
                   1228:    dealing with CFG_LIST configuration options.
                   1229:

                   1235:    file to be created. configure.in was corrected to set the default 
                   1236:    index to "thread" instead of thread.html.
                   1237: 
                   1238:  - Added .indent.pro files to FILES file.
                   1239: 
                   1240:  - Added "-p" option to mkdir so all parent directories will be made if
                   1241:    needed.
                   1242:

                   1252:    so that install-sh is used through out.
                   1253: 
                   1254:  - Assured all includes are checked for in configure.

                   1267:    and set_show_headers set to NULL initially. Othewise
                   1268:    add_list was checking garbage when called from ConfigAddItem().
                   1269:  
                   1270:  - Reworked some of the defaults in setup.c
                   1271:  
                   1272:  - Added a dump_configI() routine to print out all internal variables
                   1273:    for debugging. Use #ifdef DEBUG to get it included.
                   1274:  
                   1275:  - Removed unused defines in setup.h

                   1313:    <pixels@chez.com>
                   1314: 
                   1315:  - Updated documents about "is" and "fr" language support.
                   1316: 
                   1317:  Kent Landfield <kent@landfield.com> (Nov 9, 1999)
                   1318: 
                   1319:  - Added checking the return value of getpwuid() in readconfigs. If
                   1320:    the value is NULL then see if the $HOME is set in the environment.
                   1321:    This avoids a crash for Win32 users who don't bother to set up
                   1322:    /etc/passwd in cygwin environment.
                   1323: 
                   1324:  - Added support for proper naming of executables (hypermail on 
                   1325:    Unix hypemail.exe on Dos/Windows/NT).
                   1326: 
                   1327:  - Corrected getlocaltime so it would not print the timezone twice
                   1328:    if the timezone was also specified in the dateformat directive.
                   1329: 
                   1330:  - Corrected print.c so From: is printed when the email address
                   1331:    is the same as email name.
                   1332: 
                   1333:  - Removed tests/testhm from the baseline. Replaced it with testhm.in
                   1334:    so configure can generate the proper path to the test hypermail 
                   1335:    executable.
                   1336: 
                   1337:  - Modified configure.in so that it can determine if it is running
                   1338:    in cygwin environment. Added tests/testhm.in support.
                   1339: 
                   1340:  - Removed acconfig.h from the baseline as it is no longer needed
                   1341:    with the current configure changes.
                   1342: 
                   1343:  - Assured destination directories exist for all installed files.
                   1344: 
                   1345:  - Added uninstall option in makefiles.
                   1346: 
                   1347:  - Cleaned up the docs/Install-win32.txt to reflect the changes made.
                   1348: 
1.7       kahan    1349:  Bjarni R. Einarsson <bre@netverjar.is> (Nov 5, 1999)
                   1350: 
                   1351:  - "is" message table translation.
                   1352: 
                   1353:  - Added a stripsubject feature to hypermail, which
                   1354:    makes it remove all occurances of a given word from the subject line,
                   1355:    which is really useful for un-cluttering the subjects of some mailing
                   1356:    lists (my lists all have their subjects prefixed with [listname]: -
                   1357:    which is quite redundant in an archive).
                   1358: 
1.8       kahan    1359:  Jose Kahan <jose@w3.org> (Nov 4, 1999)
1.7       kahan    1360: 
                   1361:  - Cleaned a bit the HTML format as well as the arranging of the indexes,
                   1362:    to make them look a bit more coherent.
                   1363: 
                   1364:  - Commented the code that assumed we have an HTML text when finding a
                   1365:    line with <HTML>. The best way is to send HTML text using a correct
                   1366:    content type.
                   1367: 
                   1368:  - New configuration option, custom_archives, that allows to define
                   1369:    a proprietary HTML text to be shown in the Other mailing archives
                   1370:    item.
                   1371:  
                   1372:  - New configuration option, ietf_mbox, for parsing IETF-formatted mboxes
                   1373:    (see the doc).
                   1374: 
1.8       kahan    1375:  Jose Kahan <jose@w3.org> (Nov 2, 1999)
1.7       kahan    1376: 
                   1377:  - When using the showhtml option, </PRE> tags were being added to each
                   1378:    line of the signatures.
                   1379: 
1.6       kahan    1380:  Martin Schulze <joey@infodrom.north.de> (October 27, 1999)
                   1381: 
                   1382:  - Some where the showheaders functionality was lost. It has been
                   1383:    partially added in.  The 'hm_show_headers = list_of_RFC_Headers_to_display'
                   1384:    functionality did not work and has been corrected.
                   1385: 
                   1386:  - If the show_headers directive contains the special character ``*'',
                   1387:    hypermail will display all header lines.
                   1388: 
                   1389:  - Hypermail 2.x can now read hypermail 1.02 config files. Needed
                   1390:    to assure minimal impact of existing sites that use the older
                   1391:    version of hypermail. 
                   1392: 
                   1393:  - hmrc.4 and hypermail.1 have been updated.
                   1394: 
                   1395:  Kent Landfield <kent@landfield.com> (October 27, 1999)
                   1396: 
                   1397:  - Edited documentation to the text more readable by using two spaces 
                   1398:    after a fullstop.  
                   1399: 
                   1400:  - Cleaned up prototypes so they are consistent through out the include files.
                   1401: 
                   1402:  - Found many locations where a local variable was shadowing a global
                   1403:    variable.  Renamed certain variables to assure no compiler confusion. 
                   1404: 
                   1405:  - Extended the warning switches in WARNINGS in the Makefile.in.
                   1406: 
                   1407:  Kent Landfield <kent@landfield.com> (October 23, 1999)
                   1408: 
                   1409:  - Added additional checks in configure for the operating system. Set -Ae for
                   1410:    HP-UX and added checks for functions in libsocket and libnsl. Added sanity
                   1411:    checks to assure you are on the same machine if you are using the existing
                   1412:    config.cache and added acconfig.h config.guess config.sub support files.
                   1413:    Additional cleanup to configure.in and a regenerated configure script. 
                   1414: 
                   1415:  Scott Rose <srose@direct.ca> (October 20, 1999)
                   1416: 
                   1417:  - When a URL has trailing punctuation, it is almost certainly not part of
                   1418:    the URL. This version of parseurl() therefore excludes trailing
                   1419:    punctuation from URLs it finds.
                   1420: 
                   1421:  - If the content-description of a message was empty, and at the end of a 
                   1422:    line, the link to the associated attachment was anchored on null text. 
                   1423:    Fixed to assure the text is anchored on the filename in the generated HTML.
                   1424: 
                   1425:  Scott Rose <srose@direct.ca> (October 19, 1999)
                   1426: 
                   1427:  - Added contrib/canonicalize.pl 
                   1428: 
                   1429:    Comparing two archives is complicated by the fact that each message is
                   1430:    marked by the time at which it's archived. Attached is a script that
                   1431:    standardizes that date, if weakly, useful for such comparisons.
                   1432:    
                   1433:  - Added contrib/hyperfeed.pl
                   1434: 
                   1435:    Feed messages from an mbox into hypermail one at a time so as 
                   1436:    to test the incremental mode of hypermail.
                   1437: 
                   1438:  - The idea here is that we are zipping along through an mbox, gathering
                   1439:    information about a message, when we encounter a "From " line that signals 
                   1440:    the start of the next message. A side effect is populating dp with the 
                   1441:    date from that "From " line. In the existing code, that value is copied 
                   1442:    into fromdate[] just before the old message is hashed, which causes it 
                   1443:    to be associated with the previous message.  This caused different output
                   1444:    depending on incremental or mbox updating. This patch corrects that
                   1445:    by moving the date copy until after the addhash function is called.
                   1446: 
                   1447:  Kent (October 18, 1999)
                   1448: 
                   1449:  - Updated parseurl fuction as done by Scott Rose <srose@direct.ca>
                   1450:    provided 25% faster processing than the existing version while
                   1451:    maintaining the same functionality.
                   1452:  
                   1453:  Kent (October 8, 1999)
                   1454: 
                   1455:  - Changed msg2archive.c to be able to use the command line
                   1456: 
                   1457:  - Made changes to runtest to assure msg2archive could be tested.
                   1458:  
                   1459:  - Added the indent file .indent.pro in archive, src and lib.
                   1460: 
                   1461:  - Ran indent on all sources in archive, src, and lib.
                   1462:

                   1464: 
                   1465:  - Corrected configure.in check from gethostbyname to gethostbyaddr.
                   1466: 
                   1467:  - Added configure check for inet_addr
                   1468: 
                   1469:  - Added addition header checks and function checks in configure.in
                   1470: 
                   1471:  - Regenerated config.h.in with autoheader
                   1472: 
                   1473:  - Regenerated configure with autoconf
                   1474: 
                   1475:  - Updated the source files to use the HAVE_* definitions in config.h
                   1476:

                   1482: 
                   1483:  - Removed tests/Problems from the baseline as it was duplicating
                   1484:    KNOWN_BUGS

                   1486:  - Removed src/Formatting from the baselien as it was a junk working
                   1487:    file of mine that should never have been baselined originally.
                   1488:

                   1495:  - Added the corrected version of hypetombox.pl done by
                   1496:    Peter McCluskey (pcm@rahul.net) to the baseline.
                   1497: 
                   1498:  Jose (October 7, 1999)
                   1499:  
                   1500:  - Changed the HTML DTD string of the generated strings to HTML 4.0
                   1501:    Transitional.
                   1502:  
                   1503:  - Updated the doc to correspond to the suppression of the
                   1504:    options's hm_ prefix. Made the doc's HTML documents valid HTML 4.0 docs.
                   1505:

                   1517: 
                   1518:  - Applied Kent Landfields lots of changes. getname() is reverted to an older
                   1519:    version since the newer did out-of-bounds reads.
                   1520:

                   1528:  - Kent Landfield found a bunch of weirdnesses that were corrected, in:
                   1529:    * threadprint.c/print_all_threads()
                   1530:    * print.c, makemailcommand() usage
                   1531:

                   1533:  - (This is a big commit as I'm merging my independent developments into
                   1534:    the public hypermail tree, which I'll use from now on)
                   1535:    If there's a Content-Description header, we now use it to describe
                   1536:    MIME attachments (unless they are inlined).
                   1537:    Two new options (see the hmrc.4 or hmrc.html file for more info): 
                   1538:       + hm_uselock to turn off hypermail's internal locking mechanism
                   1539:       + hm_usemeta to store the content type of a MIME attachment in a
                   1540:         metadata file (also available thru commandline option -M)
                   1541:    If the usemeta option is turned on, the Content-Type header of an
                   1542:    attachment is stored in a .meta directory (see hmrc.4 or hmrc.html for
                   1543:    more info). 
                   1544:    Files where MIME attachments are now prefixed with a two-digit counter,
                   1545:    a la dd-name. This is to avoid having having to create temporary files,
                   1546:    and to preserver links.  The counter is incremented for each attachment,
                   1547:    regardless of it's being inline or not. I disabled the call to emptydir
                   1548:    as it's not useful (will add it as an option later on).
                   1549:    External MIME attachments that don't have a filename, are given the name
                   1550:    dd-part.
                   1551:    Improved handling of MIME rfc822 attachments. 
                   1552:    Improved handling of Content-Disposition

                   1555:  - Added configure options for --httpddir, --cgidir and --htmldir with
                   1556:    Apache's layout as the default (/usr/local/apache)
                   1557:

                   1560:    the table option was enabled.
                   1561: 
                   1562:  jose.kahan@w3.org
                   1563:  - When the boundary is declared without quotes, parse.c failed to get it
                   1564:    properly.
                   1565: 
                   1566:  - print.c: There was a missing <PRE> and this resulted in a not-readable text

1.3       kahan    1568:  Daniel (August 10, 1999)
                   1569:  - I hade a terrible bug that made the attachment directories to get created
1.4       kahan    1570:    relative the wrong directory! They were also not getting the proper
                   1571:    permissions set.

                   1579:   - I'm consider renaming the series of archives that I'm releasing, back to
                   1580:     the beta label. It would be more correct. Kent is with us again and I
                   1581:     don't think anyone is gonna continue on the now forever sleeping
                   1582:     beta-series. This seems to be the one and only hypermail development
                   1583:     branch and I believe we now have it stable enough.
                   1584: 
                   1585:   - 'attachmentlink' is a new config file item that controls how attachments'
                   1586:     links are made. By using this you can make a wrapper cgi script on your
                   1587:     server that issues a warning to the user that it may be dangerous to run
                   1588:     attachments or whatever you think is appropriate. Default it behavs as it
                   1589:     used to do before this feature was added.

                   1592:   - Applied Jose Kahan <Jose.Kahan@inrialpes.fr>'s patches:
                   1593:  
                   1594:     The alternate content parsing was broken in that you couldn't give a list
                   1595:     of preferences. Also, if you first parse an alternate with a low priority,
                   1596:     then another one with a higher priority, the memory and, eventually, files
                   1597:     created to store the former alternate content weren't erased.
                   1598: 
                   1599:     I found a minor bug. When decoding messages with multiple MIME
                   1600:     attachments, the decode variable (where the content encoding format is
                   1601:     stored), isn't updated.

                   1603:   Daniel (August 6, 1999)
                   1604:    - Fixed the subject overflow
                   1605: 
                   1606:    - Made attachments get saved in their own subdirectories.

                   1611:   - I'm making a release out of this now since I'm off for a longish

                   1615: 
                   1616:   - Applied Tom van Alten's patch to correct improper formatting 
                   1617:     of messages when hm_showhtml = 0 and showheaders = 1.
                   1618: 
                   1619:   - New code to (optionally) accept messages wth no msgid.  Default
                   1620:     is to require msgids in all messages - use hm_require_msgids = 0 
                   1621:     to avoid this check.
                   1622: 
                   1623:   - Made handling of duplicate msgids optional.  By default duplicates
                   1624:     are discarded.  To accept them (replacing the msgid with a generated
                   1625:     msgid) use hm_discard_dup_msgids = 0.
                   1626: 
                   1627:   - Check return value from addhash when reading old messages.  Messages
                   1628:     already archived should be valid but safer to check.

                   1632:   Daniel
                   1633:   - Applied a boundary parsing bug correcting patch supplied by
                   1634:     Andreas Fuchs <asf@ycom.at>
                   1635:

                   1637:   o (May 16th 1999)
                   1638:     1) changes to the way we construct threadlist (so that all the messages
                   1639:     that should be in the thread are included even if they don't have valid
                   1640:     in-reply-to headers)
                   1641: 
                   1642:     2) changes to threadprint.c - simplification of print_all_threads.  Now
                   1643:     uses the information in threadlist to find the relationship between
                   1644:     messages.  This speeds things up a bit when adding single messages to
                   1645:     large archives (I saw a reduction from 28s to 18s for adding a message to
                   1646:     a 1,100 message archive).  Slight speed-up when converting large archives
                   1647:     - not as noticeable as a large part of time now seems to be in fopen().
                   1648: 
                   1649:     I've updated/added some comments.
                   1650: 
                   1651:     I've added msgnum to the reply struct - this is just a copy of msgnum in
                   1652:     ->data->msgnum - this was intended as an optimisation but I suspect it
                   1653:     doesn't make much difference.
                   1654: 
                   1655:     Threading is now much better (well, I would say that wouldn't I :->).  it
                   1656:     still gets things wrong occasionally - often not really its fault.  Known
                   1657:     problems include
                   1658: 
                   1659:     1) duplicate message-ids - results in messages being attached to the wrong
                   1660:     thread - actually found an instance of this in my test mailbox.  The
                   1661:     obvious heuristic to avoid this would be to compare the subject as well,
                   1662:     though this breaks threads where the sender has deliberately changed the
                   1663:     subject but intends to continue the thread.
                   1664: 
                   1665:     2) occasionally gets messages in the wrong order because they get attached
                   1666:     to different sub-threads - wouldn't happen if MUAs used in-reply-to.
                   1667: 
                   1668:     I've done a quick tweak to duplicate msgid handling in addhash.  Now
                   1669:     replaces duplicate msgids with a locally constructed one.  This keeps
                   1670:     things happier.

                   1676:   o (May 12th)
                   1677:     - Added the tests/stdintest.pl script. It is a small perl hack that passes
                   1678:       a series of generated mails into hypermail on stdin. One by one. I've
                   1679:       got reports about bugs in that area, but I can't seem to repeat any
                   1680:       with this tool. I thought I'd better include this here anyway to better
                   1681:       enable others to run more torture tests on hypermail.

                   1685:   o (May 6th)
                   1686:     - Here's a patch that allows the user to decide on the format used to
                   1687:       present dates on the generated pages.  If dateformat is set then it uses
                   1688:       that (that's the new functionality) otherwise it uses the standard
                   1689:       format or euro format depending on the config file.
                   1690: 
                   1691:       I've not given the option to use the date string as originally given in
                   1692:       the mail message.  This could be done without too much hassle.

                   1697:     - Corrected a crash in parse.c
                   1698: 
                   1699:     - Added a missing "From:" in print.c
                   1700: 
                   1701:     - Made the bin-names get prefixed with "att-" too.
                   1702: 
                   1703:     - Adjusted getname() to skip all starting white spaces and quotes, and
                   1704:       to skip trailing quotes as well as white spaces.
                   1705: 
                   1706:   o (May 4th)

                   1714:    - Implementing my new From:-parser into the new source file: getname.c.
                   1715:      This should hopefully not only be much better at parsing from lines,
                   1716:      but also to it in a more stable manner.
                   1717: 
                   1718:    - Found some additional problems with From-lines I've tried to correct.
                   1719:      Like a single-mail archive or mails with no From:-lines at all.

                   1731: 
                   1732:   o Several errors correct, most of them by Paul Haldane.

                   1740:     - Added 'locktime' as a configurable item. It defines the maximum number
                   1741:       of seconds to wait for an existing lock to dissapear before it is
                   1742:       overridden. If this is 0 or less, the lockfile will lose its power
                   1743:       completely. locktime is 3600 by default.
                   1744: 
                   1745:     - I made the 'indextable' option work as Glen Steward wanted it to (that
                   1746:       March 30 patch apply wasn't such a big hit). You can either set
                   1747:       "indextable = on" in the config file or use the -T command line option
                   1748:       to get the indexes in "table" version.

                   1761:   o (Mar 30, 1999)
                   1762:     - First atttempt at applying Glen Steward's table patches. It wasn't
                   1763:       a complete success but it can be adjusted from here.
                   1764: 
                   1765:   o (Mar 29, 1999)
                   1766:     - Ashley M. Kirchner found a silly bug that occured if the last mail
                   1767:       in the box was a double message-id (or similar that makes that
                   1768:       particular function return NULL).
                   1769: 
                   1770:   o (Mar 25, 1999)
                   1771:     - Threaded index seems to work yet again!
                   1772:     - Paul Haldane <Paul.Haldane@newcastle.ac.uk> brought me lots of
                   1773:       various patches that made hypermail do better! 
                   1774: 
                   1775:   o (Mar 25, 1999)
                   1776:     - Corrected the problem with "re: subject" and "subject" being sorted
                   1777:       differently. The explanation was that the "re:" subject had a space
                   1778:       left in the beginning of the string!
                   1779: 
                   1780:   o (Mar 25, 1999)
                   1781:     My giant work of redoing things now finally seems to work a little at
                   1782:     least. What's been done the last week:
                   1783:     - All emails now get only ONE single struct allocated for it.
                   1784:     - Remade the hash stuff. Hashed entries in the table only stores a struct,
                   1785:       links it in the list and POINTS to the email struct.
                   1786:     - Added a hash on the 'inreplyto' string to better enable finding mails
                   1787:       a mail replies to.
                   1788:     - Rewrote the whole darned threaded index functions. threadprint.c is a
                   1789:       new source file for threaded index functions.
                   1790:     - All indexes will now have full access to the complete email struct and
                   1791:       will thus enable dates all over etc. This will enable me to introduce
                   1792:       a template feature for how to write an entry in an index. I.e what to
                   1793:       include for each entry, subject, author, date, charset, bla bla bla...
                   1794:     - Changed the way single mail's "next in thread" links are found.
                   1795:     - As a "side-effect" I added a filter to prevent the same message ID
                   1796:       twice. The reason for this is that it is more likely for it to be able
                   1797:       to screw up the threading if I allow them to co-exist.
                   1798: 
                   1799:   o Ashley M. Kirchner <ashley@pcraft.com> works on the bug report web.
                   1800: 
                   1801:   o (Mar 15, 1999)
                   1802:     Roman Shterenzon <roman@xpert.com> pointed out a bug in the HTML-reader
                   1803:     that made hypermail crash if the variables were set to "". I mailed back
                   1804:     a patch to him I think will correct this problem.

                   1811:     "text_types" is now a recognized config file item, where you can specify
                   1812:     MIME types that should be treated by hypermail _exactly_ as if they were
                   1813:     text/plain.
                   1814: 
                   1815:   o Corrected the list-check routine, so that the items in the list are the
                   1816:     ones using wildcards. This means that suddenly, all those mime-list items
                   1817:     support wildcards!
                   1818:

                   1820:     Craig A Summerhill <craig@cni.org> found a bug. It turned out to be the
                   1821:     fact that parse.c wronly assumed content-type text/plain to use
                   1822:     ENCODE_NORMAL. It was really silly, since the Content-Transfer-Encoding
                   1823:     header could've already appeared and stated another encoding!
                   1824: 
                   1825:   o Adjusted configure.in to do a slightly better -libnsl check.
                   1826: 
                   1827:   o (Mar 11, 1999)
                   1828:     CVS server is up again. Added the UPGRADE file to the tree. Thanks to
                   1829:     Glen Stewart.
                   1830: 
                   1831:   o (Mar 10, 1999)
                   1832:     Pretty extensive re-write of parse.c to deal with the
                   1833:     "Content-Disposition" headers better. That line can give a hint whether
                   1834:     the file should be stored as a file or showed inlined. It can also
                   1835:     have the filename (RFC1806 for details).
                   1836:

                   1838:     The CVS server is down due to admin work there.
                   1839: 
                   1840:   o (Mar 10, 1999)
                   1841:     Fixed parseurl(). It now deals with <www.foobar.com> and similar
                   1842:     constructions better. Craig A Summerhill <craig@cni.org> reported.
                   1843: 
                   1844:   o (Mar 8, 1999)
                   1845:     Corrected src/Makefile.in to not use options.h anymore!
                   1846:     Roman Shterenzon <roman@xpert.com> made me aware of this.

                   1852:   o (Mar 5, 1999) Made "text" equal text/plain in content-type: header
                   1853:     lines.
                   1854: 
                   1855:   o Removed options.h completely to reduce the number of mistakes from
                   1856:     people trying to edit it!
                   1857: 
                   1858:   o (Mar 4, 1999) Applied Glen Stewart's patch to remove a few <li> tags.
                   1859: 
                   1860:   o Bailey, Raymond <bailey9@MARSHALL.EDU> pointed out a problem in the
                   1861:     getname() function. When you got a mail with a From: line where there
                   1862:     is a name within quotes that were "attached" to the email part without
                   1863:     spaces in between as in "name"<email@email.com> the parser failed to
                   1864:     get a name part of this and caused hypermail to dump core.
                   1865: 
                   1866:   o Alisdair Davey <ard@mithra.physics.montana.edu> Helped me point out
                   1867:     a bug in mprintf.c. It made the *printf() routines fail on %.*s
                   1868:     constructions. I am considering an upgrade of the mprintf stuff to
                   1869:     my newer "trio" stuff...
                   1870: 
                   1871:   o Made %f insert the file name of the generated HTML file in headers

                   1879:     a "in-relpy-to" header but the replied-to mail was not present in the

                   1897: 
                   1898:   o Updated the "name/email" scanner.

                   1909: 
                   1910:   o (parse.c) now the QP decoder accepts question marks in the encoded-words
                   1911: 
                   1912:   o Corrected the mprintf() replacement define in mprintf.h
                   1913: 
                   1914:   o Added some more missing free()s in print.c

                   1923: 
                   1924:   o List types in the config were insanely written and caused memory
                   1925:     disaster at times. Byron C. Darrah <bdarr@sse.FU.HAC.COM> and
                   1926:     Jenni Baier <jenni@renewed.net> both probably experienced this.
                   1927: 
                   1928:   o Decreased the amount of memory allocations used when building hash
                   1929:     tables for index sorting. (see addhash() in struct.c)

                   1943: 
                   1944:   o %c is recognized and replaced with a charset tag in mail headers. It
                   1945:     should be set as early as possible within the HEAD tag.
                   1946: 
                   1947:   o Saves <!-- charset=blablabla --> in articles.
                   1948: 
                   1949:   o dprintf() was not a successful name, Linux uses it for some odd purpose
                   1950:     even in stdio.h! :-/ Renamed my line of functions to m*.
                   1951: 
                   1952:   o Adjusted getname() to be slightly smarter.
                   1953: 
                   1954:   o Started working at adding charset to each single mail. It should be stored
                   1955:     per-mail basis now, even though it is never used anywhere...  It should
                   1956:     now make a proper META HTTP-EQUIV tag!

                   1962: 
                   1963:   o Added a new -o option that can set any config options on the command line.
                   1964:     E.g set label with -o "label=my new label".
                   1965: 
                   1966:   o Major rewrites of struct.c. There were just too many functions that
                   1967:     passed data between them by strcpy()ing them to char buffers. They now
                   1968:     pass char pointers in a lot higher degree. In fact, there aren't that
                   1969:     many strcpy()s left in the source now. Not that I notice any faster
                   1970:     operations, I just know it is neater code.
                   1971: 
                   1972:   o I really don't like the way proto.h has *ALL* prototypes and therefore
                   1973:     everything is dependent on that file. I've stared to slowly extract the
                   1974:     protos for each .c file into its own .h file. This will allow me to
                   1975:     change prototype for a single function without having to recompile the
                   1976:     whole lot.
                   1977: 
                   1978:   o Added general "Re:" - awareness functions. isre() returns TRUE if the
                   1979:     input string starts with a re-thing and findre() returns the position
                   1980:     of the first instance of re in the input string, or NULL if there is
                   1981:     none.
                   1982: 
                   1983:     It knows and recognizes "Re:", "Fw:" and "Re[<number>]:" strings. If we
                   1984:     ever intend to support local variations of this, I've now made that
                   1985:     easier...
                   1986: 
                   1987:   o The new getname() had problems with parens in the real name part when
                   1988:     quoted. As in 
                   1989:     From: "Windle, Alan M. (PA62)" <test@site.com>
                   1990:     It shouldn't be a problem now. It should also work with from-lines like:
                   1991:     From: ("Windle, Alan M. (PA62)") test@site.com
                   1992: 
                   1993:     There might be an idea to simply ignore everything within that level of
                   1994:     parentheses. I mean, not add that text to the name.
                   1995: 
                   1996:   o The sorted datelist was broken because I must've destroyed unre() when I
                   1997:     turned it dynamic. I improved printsubjects() to deal with pointers and
                   1998:     it now strcpy()s a lot less data.
                   1999:     
                   2000:     Did the same change to the printauthors() too.
                   2001: 
                   2002:   o increment and readone are now separate options. Read stdin or use mailbox
                   2003:     are mutually exclusive but don't modify increment or readone. The
                   2004:     previous system was very confusing and didn't allow e.g updating an
                   2005:     archive with two mails passed on stdin!
                   2006: 
                   2007:     I've now tried to update an existing archive with 3 mails passed on stdin
                   2008:     and it seemed to work. Works if read from a mailbox too. Even works with
                   2009:     the new -1 flag (to indicate there's one mail only). It has an
                   2010:     accompanying config file keyword named 'readone'. I think the new -v flag
                   2011:     is really great for this, cause it shows all built-in variables and kind
                   2012:     of automatically documents them!
                   2013: 
                   2014:   o Ok, I wasn't aware the config file did assume quotes around the strings.
                   2015:     I've added support for that (too) now. Distributed this small change
                   2016:     to Kent, Tom and John as a patch for 2b8.
                   2017:

                   2021:   Daniel
                   2022: 
                   2023:   (Nov 24, 1998)
                   2024:   o So, just before I was gonna announce the b7 to the guys I got another
                   2025:     report from John Petrakis that pointed out two bugs. One bad free() which
                   2026:     he identified and one From:-line that b7 couldn't get name and email from
                   2027:     properly. I got really tired and rewrote the whole getname() function to
                   2028:     work with all the combinations mentioned in the source, and more. I think
                   2029:     this function also has another benefit: it is easier to read than the old
                   2030:     one.
                   2031: 
                   2032:   o I found some other bugs with my new setup system which caused the
                   2033:     hm_htmlbody = NONE to not work. I am actually against that a line that
                   2034:     says NONE sets it to the default. NONE should be NONE, if the keyword
                   2035:     isn't used at all it should use the default. Well well, one thing at a
                   2036:     time I guess.
                   2037:     
                   2038: 
                   2039: 2.0b7
                   2040: =====
                   2041: 
                   2042:   Daniel (getting deeper and deeper into this now ;-)
                   2043: 
                   2044:   o Entirely new config file parser. Does make adding new config items a
                   2045:     lot easier and smoother. Run hypermail -v to make it output a fully
                   2046:     working config file (after reading the given input parameters).
                   2047: 
                   2048:     There is no need for the "hm_" prefix on keywords in the config file. You
                   2049:     can still use it if you want, but you don't have to.
                   2050: 
                   2051:     Internally, all configurable variables are now named 'set_XXXXX' to better
                   2052:     make it visible in the code.
                   2053: 
                   2054:   o readoldheaders() is a lot more robust now. The order of the variables are
                   2055:     not set and empty files no longer cause it to dump core.
                   2056: 
                   2057:   o Hypermail from now on only stores the variables inside HTML files that
                   2058:     are actually set. name="" is not needed to store.
                   2059: 
                   2060: 2.0b6
                   2061: =====
                   2062: 
                   2063:   Daniel continues:
                   2064: 
                   2065:   o parseemail() and ConvURLs() needed to deal with NULLs better.
                   2066: 
                   2067:   o loadoldheaders() are no longer dependent on the order of the variables
                   2068:     in previously written HTML files.
                   2069: 
                   2070:   o Mails with no subject confused the parser.c
                   2071: 
                   2072:   o Tom von Alten <Tom_vonAlten@boi.hp.com> sent me two files he appearantly
                   2073:     got from Kent after the b4 he sent me. (date.c and msg2archive.c)
                   2074: 
                   2075:   o All kinds of lists like hm_show_headers, hm_inline_types and
                   2076:     hm_ignore_types now offer the below mentioned wildcards.
                   2077: 
                   2078:   o Added dmatch.c for dos-style * and ? wildcard matching.
                   2079: 
                   2080:   o Cleaning up more memory leaks.

                   2083: ==========================================
                   2084: 
                   2085:   Daniel:
                   2086: 
                   2087:   o Added 'maketgz' to the archive. It is for creating release archives,
                   2088:     without having to remove a lot of files first.
                   2089:     * first asks for the version number of choice
                   2090:     * uses the file FILES to know what files to include.
                   2091:     * updates the patchlevel.h file to the entered version number
                   2092:     * creates the archive with a directory based on the entered version number 
                   2093:     * names the archive based on the entered version number
                   2094: 
                   2095:   o Added a whole bunch of more free() calls.
                   2096: 
                   2097:   o Inlined HTML that was base64 or uuencoded were not previously dealt with
                   2098:     properly.
                   2099: 
                   2100:   o Mails with no Message-Id: caused a crash in the hash function.
                   2101: 
                   2102:   o HM_INLINEHTML can now be set to 0 to prevent hypermail from inlining
                   2103:     mail parts in HTML.

                   2107: 
                   2108:   Daniel:
                   2109: 
                   2110:   o Dynamic strings all over. I added a generic dynamic-string system which
                   2111:     I think works pretty good. Using functions and macros it should also be
                   2112:     pretty easy to extend, modify and optimize without any other source
                   2113:     modifications. 
                   2114: 
                   2115:     I had to modify stuff all over the place and pretty much too. I hope I've
                   2116:     removed at least the worst uses of static buffers and my initial tests
                   2117:     prove me right. No lenght limits of any fields of a mail is my goal, and
                   2118:     I think it is a fair goal.
                   2119: 
                   2120:     Beware of leaking memory now though. We need to setup some debug-system
                   2121:     to track them easily.
                   2122: 
                   2123:     The dynamic string routines could very well be optimized too.
                   2124: 
                   2125:   o My dsprintf system was added. This system offers snprintf() - sprintf with
                   2126:     a buffer length parameter and aprintf() - returns an allocated string with
                   2127:     the text. I did this to better deal with fully dynamic buffers.
                   2128: 
                   2129:   o Corrected the swedish texts. All 8bit letters were gone!
                   2130: 
                   2131:   o (Nov 16) I recevied the 981013-b4 version. Started work.
                   2132: 
                   2133: 2.0b4
                   2134: ====================
                   2135: 
                   2136:   Kent:
                   2137:  
                   2138:   o Date routine corrections.  
                   2139: 
                   2140:        - Y2K capable. Hypermail used a two digit representation
                   2141:          for the year through out. It now uses a 4 digit representation.
                   2142: 
                   2143:        - In hypermail.h, October was listed in monthdays as only having
                   2144:          30 days.
                   2145: 
                   2146:        - hypermail did not deal with all the major date string formats. 
                   2147:          Date: formats starting with a digit (09 Sep 1998 01:27:30 +0300)
                   2148:          would cause parsing and threading problems. It now supports
                   2149:          that format.
                   2150: 
                   2151:        - Added code to deal correctly with two digit years.
                   2152:          The idea as to how to approach this and the basis for
                   2153:          the solution is thanks to Byron Darrah.
                   2154: 
                   2155:        - Corrected an off by one day error in getyearsecs(). It was 
                   2156:          adding the current day && adding the hours, minutes, and seconds 
                   2157:          for that day as well. It only needed to count all the days UP TO
                   2158:          the current day and then add the hours, minutes, and seconds for
                   2159:          the current day.
                   2160: 
                   2161:        - Incorrect data type passed to fprint_summary(), needed to be
                   2162:          long instead of int.
                   2163: 
                   2164:        - Corrected an off by one day in getdatestr(). Days in a month
                   2165:          start at 1, not 0.
                   2166: 
                   2167:  
                   2168:   o Add the ability to save hypermail generated html files with any 
                   2169:     configurable html suffix such as ".htm", ".html" or ".shtml", etc.
                   2170:     This works for the index files as well as the message files. (New 
                   2171:     .hmrc variable, hm_htmlsuffix, new environment variable HM_HTMLSUFFIX, 
                   2172:     and HTMLSUFFIX define in options.h.)
                   2173: 
                   2174:   o Removed a conditional "if (use_mbox) increment = 0;" that was 
                   2175:     preventing the ability to read one message from a file and update 
                   2176:     an existing archive and its indexes.
                   2177: 
                   2178:   o Corrected parseurl to allow for a ',' (comma) character to be embedded
                   2179:     in the URL.
                   2180: 
                   2181:   o Corrected parseurl to allow for a '&' (ampersand) character to be embedded
                   2182:     in the URL.
                   2183: 
                   2184:   o Using -p with -iu on a new archive directory caused a core dump
                   2185:     begause 'bignum' was zero.  Corrected to assure bignum > 0.
                   2186: 
                   2187:   o Added language abilities to hypermail. 
                   2188:          English  - en
                   2189:          Spanish  - es
                   2190:          German   - de
                   2191:          Swedish  - se
                   2192:     initially supported. (lang.c and lang.h added.)
                   2193: 
                   2194:     Thanks to Francisco Iacobelli <fiacobelli@ibersis.cl> for the
                   2195:     "es" message table translation.
                   2196: 
                   2197:     Thanks to Martin Schulze <joey@kuolema.Infodrom.North.DE> for the
                   2198:     "de" message table translation.
                   2199: 
                   2200:     Thanks to Daniel Stenberg <Daniel.Stenberg@sth.frontec.se> for the
                   2201:     "se" message table translation.
                   2202: 
                   2203:   o Changed how error messages are displayed so options message
                   2204:     only displayed where appropriate instead of for every message.
                   2205: 
                   2206:   o Corrected getname() to parse yet another funky name format.
                   2207: 
                   2208:   o Corrected printing error when a invalid domain was encountered in
                   2209:     an email address.
                   2210: 
                   2211:   o Converted some static internal buffers to dynamically allocated ones
                   2212:     at startup saving 6+K. Also resulted in setstrval() not being needed
                   2213:     so it was removed.
                   2214: 
                   2215:   o Corrected MIME parsing problem with previously parsed headers.
                   2216: 
                   2217:   o Corrected default labeling problem with stdin generated archives
                   2218:     when no label is supplied.
                   2219: 
                   2220:   o Fixed hypermail so it would not crash if started with no arguments
                   2221:     and an article on stdin.
                   2222: 
                   2223:   o Added locking to the archive so that there is less chance of corruption
                   2224:     of the archive due to multiple copies of hypermail trying to update
                   2225:     the same archive at the same time with multiple messages.  This could
                   2226:     be improved so as to check for pid of process that owns it...
                   2227: 
                   2228:   o Extended the configure support.
                   2229: 
                   2230:   o Extended the use of hm_progress so that more information about
                   2231:     attachment files can be displayed.
                   2232: 
                   2233:   o Updated documentation to reflect changes
                   2234: 
                   2235:   o Corrected getname to deal with names that are all spaces.
                   2236: 
                   2237:   o Corrected configuration variable setting. Moved checks to the
                   2238:     right place in the code.
                   2239: 
                   2240:   o Hypermail now supports listproc mailboxes as well as general Unix
                   2241:     formated mailboxes. It does not require that a blank line exists 
                   2242:     between mail messsages in a mailbox. Thanks to Craig A Summerhill 
                   2243:     <craig@cni.org> for the push and the test data.
                   2244: 
                   2245: 2.0b3  - 8/15/98 
                   2246: =================
                   2247: 
                   2248:   o Added validation of domains so that the generation of mailto: is
                   2249:     much more accurate than the previous method.
                   2250: 
                   2251:   o Added support for Content-Disposition MIME Header so as to get the
                   2252:     filename from the header.
                   2253: 
                   2254:   o Added verification of filenames to assure they are safe to use and
                   2255:     will not cause filesystem problems
                   2256: 
                   2257:   o Fixed a problem with parsing the ending MIME boundary (it expended headers
                   2258:     following that)
                   2259: 
                   2260:   o Found and removed a one-byte buffer overflow in the line continuation code.
                   2261: 
                   2262:   o Corrected docs/hypermail.1 and TODO to reflect the proper RFC 822
                   2263:     parsing was actually included in version 2.0b1
                   2264: 
                   2265:   o Corrected a typo in string.c that prevented the proper generation 
                   2266:     of mailto: links for email names with numbers [0-9] in them. 
                   2267: 
                   2268:   o Corrected the base64 decoder error which caused files to get an 
                   2269:     extra zero-byte appended at times. (When storing attachments to disk.)
                   2270: 
                   2271:   o Added additional ported systems to the README
                   2272: 
                   2273:   o Removed the "#ifndef" from the defines in options.h. We do not want to
                   2274:     inherit any define values from other places. If there are confilcts
                   2275:     then I need to correct them. Inheriting defines can lead to unforeseen
                   2276:     results.
                   2277: 
                   2278:   o attachments:
                   2279:        - comments are now generated in the output mail for each attachment 
                   2280:          that is written in a separate file. The comment looks like:
                   2281:             '<!-- attachment="filename" -->' in the standard comment style. 
                   2282: 
                   2283:   o buffers and overflows
                   2284:     - mdecodeRFC2047() now has an output buffer size argument
                   2285:     - had to remove the use of rmcr() at two places, since that function uses
                   2286:       a very strict static buffer limiting the maximum line length pretty bad.
                   2287:     - parseurl() now features an output buffer size argument
                   2288:     - parseemail() now features an output buffer size argument
                   2289:   
                   2290:   o multipart/alternative 
                   2291:     - added awareness and parser "intelligence" to pick the last prefered
                   2292:       content-type within a series of alternatives (as MIME tells us to
                   2293:       do). This has not yet been very thoroughly tested.
                   2294:     - added the preferedcontent() function that returns wether a content-type
                   2295:       is prefered or not (as set with hm_prefered_types). Default prefered 
                   2296:       type is 'text/plain' (if hm_prefered_types is unused).
                   2297:   
                   2298:   o output
                   2299:     - added the experiment function printhtml(). It strips off unwanted html
                   2300:       tags from the output, even if they are used in attached HTML files. I.e
                   2301:       <HTML> and </HTML>.
                   2302:     - made 'showheaders' not use <BR> or newlines since the BRs are ignored
                   2303:       anyway, and the newlines are already present in each header line.
                   2304:     - added 'hm_show_headers' which is a list of what headers to include when 
                   2305:       the 'showheaders' option is used. For now, it also controls which 
                   2306:       headers to show when attached mails are shown. Although I can imagine 
                   2307:       that you'd like separate lists (since for attached mails, you'd like i.e
                   2308:       subject which you may not need for the main mail itself). If 
                   2309:       'hm_show_headers' isn't used, all headers will be shown.
                   2310:     - made the <PRE> system in the printbody() function a little smarter, and
                   2311:       now it prevents multiple </PRE> and <P> tags better. It did however
                   2312:       introduce another side effect (although a less serious one imho) and 
                   2313:       that is an extra pair of <PRE></PRE> after the last attachment when 
                   2314:       using 'showhtml'.
                   2315:   
                   2316:   o parsing
                   2317:     - made the multi-line merger function to make all lines get a regular 
                   2318:       white space between them when they're put together. Previously, this 
                   2319:       character was left as-is, which could be a space or a tab (or any other 
                   2320:       isspace()) letter.
                   2321:     - check changed to check for "<!-- received" as the start of parsing
                   2322:       previous html files in the event that the archive maintainer whishes
                   2323:       to add comments in the header template HTML files.
                   2324:     - in_list() now checks for list items case insensitive
                   2325:     - corrected so Message-ID:, References and Supersedes: lines are not
                   2326:       converted into mailto: URLs.
                   2327:     - corrected off-by-one in isquote that was causing array boundary read 
                   2328:       errors.
                   2329:     - corrected off-by-one in printbody line output that was causing array
                   2330:       boundary read errors.
                   2331: 
                   2332: Real thanks are in order for Daniel Stenberg and David D. Kilzer. They helped
                   2333: greatly with making this release possible by sending in enhancements, comments
                   2334: and bug fixes.  Thanks Guys!
                   2335:   
                   2336: 2.0b2  - 6/07/98 
                   2337: =================
                   2338: 
                   2339:   o Corrected command line processing for individual messages received 
                   2340:     on standard input.
                   2341: 
                   2342:   o Corrected formating of Next message links when incremental updating 
                   2343:     is done.
                   2344: 
                   2345:   o Corrected the template filenames in docs/hmrc.html. Added "file" 
                   2346:     to them.
                   2347: 
                   2348:   o Added additional systems to the list of ported systems.
                   2349: 
                   2350:   o Reset certain options back to the proper defaults.
                   2351: 
                   2352:   o Corrected problem in printbody in regards to printing HTML embedded
                   2353:     in a message. Still work to do here.
                   2354: 
                   2355:   o Changed address options to assure I didn't get landfield.com 
                   2356:     information inadvertantly set in hundreds of archives because
                   2357:     the admins just took the defaults. ;)
                   2358: 
                   2359: 2.0b1  6/05/98 - Kent Landfield
                   2360: ===============================
                   2361: 
                   2362: WARNING: There have been too many changes to this version to list them
                   2363:          all here.  What appears below are some of the highlights.
                   2364: 
                   2365:   o Command line settings override what is in the config file. In the
                   2366:     past the command line variables were read and set before the config
                   2367:     file was read. (Needed to get the name of the config file from the
                   2368:     command line.) This made it hard to have a default list configuration
                   2369:     file and make single runs with only one variable changed. Now processing
                   2370:     sets the hypermail internal options by:
                   2371:   
                   2372:        Using Compiled in defaults specified in options.h,
                   2373:             then reads Hypermail Environment variables if set,
                   2374:             then looks for and reads any Configuration file specified
                   2375:         and finally uses the Command line settings specified by the user.
                   2376: 
                   2377:     NOTE: THIS IS DIFFERENT THAN PAST HYPERMAIL USAGE.
                   2378:   
                   2379:   o Configurable Setting (.hmrc file) or Compile Time Variable to 
                   2380:     Domain-ize Addresses -- addresses appearing in the RFC822 field 
                   2381:     which lack hostname can't be made into proper HREFs when Hypermail
                   2382:     does it's thing.  They are coded with:  mailto:(no%20email)
                   2383:   
                   2384:     Because the MTA resides on the same host as the list, it is 
                   2385:     often not require to domain-ize these addresses for delivery.
                   2386:     In such cases, I think it would nice if Hypermail could be 
                   2387:     programmed to output:  mailto:kent@landfield.com  instead.
                   2388:     This would probably work well as a *required* definition 
                   2389:     during compilation; however, it should not simply rely on 
                   2390:     the output from `hostname` in case you want to override with 
                   2391:     an MX entry or alternate domain (if you run virtual domains)
                   2392:   
                   2393:   o Added capability to have customizable index html headers, message
                   2394:     html headers and html footers.  Able to use substitution cookies in 
                   2395:     the header and footer template files.
                   2396:   
                   2397:        Substitution cookies supported:
                   2398:   
                   2399:            %% - '%' character
                   2400:            %~ - storage directory
                   2401:            %e - email addr of message author - Not valid on index pages
                   2402:            %h - HMURL
                   2403:            %i - Message-id - Not valid on index pages
                   2404:            %l - archive label
                   2405:            %m - Mailto address
                   2406:            %p - PROGNAME
                   2407:            %s - Subject of message or Index Title
                   2408:            %v - VERSION
                   2409:            %u - Expanded version link (HMURL,PROGNAME,VERSION)
                   2410:            \n - newline character
                   2411:            \t - tab character

                   2421:   o Generates META tags in articles Author and Subject.
                   2422:   
                   2423:   o Now uses "configure" to generate the makefiles. This is rather
                   2424:     weak at present and needs to be added to/tested on other systems
                   2425:     but at least it's a start.
                   2426:   
                   2427:   o The config.h was renamed to options.h to support configure usage.
                   2428:   
                   2429:   o patchlevel.h added to facilitate better patches in the future. Still

                   2431:   
                   2432:   o Added example .rc files to show how to customize list's and their
                   2433:     looks. 
                   2434:   
                   2435:   o Removed the _print.c files that had existed in the 103b2 release and 
                   2436:     replaced them with template headers/footer files. 
                   2437:   
                   2438:   o Extended archive path creation to make missing directories.
                   2439:   
                   2440:   o Added capabilities dir pathing to allow archive creation by date

                   2456:     Subsequent executions will put the messages in the directories 
                   2457:     according to the date the messages were received on the archive 
                   2458:     site.
                   2459:   
                   2460:   o All "mailto:" links can include the "subject" so that the Subject: 
                   2461:     line of netscape mailer is automatically filled in.
                   2462:   
                   2463:   o Fixed "Re:" and redundant "Re:" variation && MS FW... 
                   2464:   
                   2465:   o Greatly enhanced getname() to correctly deal with most all email 
                   2466:     addresses.  X.400 addresses are not well supported yet. 
                   2467:   
                   2468:   o Corrected getreply() to better support the In-Reply-To: formats. The 
                   2469:     routine needs to revisited when a readline routine is inserted to
                   2470:     properly deal with continuation lines.
                   2471:   
                   2472:   o Added additional documentation describing the Hypermail configuration 
                   2473:     file.
                   2474: 
                   2475:   o Added additional documentation describing how to customize HTML 
                   2476:     generated pages.
                   2477:   
                   2478:   o Corrected many petty problems such as:
                   2479:      - recursive '%' substitution.  A % in a subject line could cause 
                   2480:        an ugly recursion problem in a mail command expansion.
                   2481:      - title length problem.  Length of a title needs to be limited to 
                   2482:        less than 64 characters as indicated by HTML specs.
                   2483:      - Weblinted the generated output and corrected various things.
                   2484:      - Removed unused and unneeded variables
                   2485: 
                   2486:   o Change various storage length defines in hypermail.h

                   2497:   o Corrected one of the Message-ID bugs, 
                   2498:   
                   2499:   o Removed annoying #start/#end fragments that mess up the browser history.

                   2503: 
                   2504:   o Added a menu bar for a header and footer on all pages and removed 
                   2505:     the bulleted list items that it replaces.  
                   2506:   
                   2507:   o Reworked the general appearance of header and footer parts of html pages.
                   2508:   
                   2509:   o Added the "hm_hmail" configuration parameter and -n command line
                   2510:     option for specifying an email address for input to a hypermail
                   2511:     archive.
                   2512:   
                   2513:   o Added "New Message" and "Reply" buttons to the menu bar for submitting
                   2514:     messages to a hypermail based list.

                   2520:   
                   2521:   o SHOWBR, IQUOTES, SHOWHR, EURODATE, SHOWREPLIES, and MAILCOMMAND 
                   2522:     now run-time configurable.  
                   2523:   
                   2524:   o Fixed post leap-day error.  
                   2525:   
                   2526:   o More robust Message-ID parsing.  
                   2527:   
                   2528:   o Better SHOWHTML handling for indented lines.

                   2533: --------------------------------------------------------------------------
                   2534: 
                   2535:   o I had all calls to the decodeRFC2047() function moved to *after* the
                   2536:     merging of long lines.
                   2537:   
                   2538:   o decodeRFC2047() now correctly concatenates two succeeding "encoded words".
                   2539:     I now call the function mdecodeRfc2047() since it now allocates the new
                   2540:     string.
                   2541:   
                   2542:   o Now informs if the attachment wasn't properly decoded when stored to disk.
                   2543:     This happens if the Content-Transfer-Encoding specified isn't known to
                   2544:     the parser. When this happens, the attachment is stored as 8bit octet-
                   2545:     stream.
                   2546:   
                   2547:   o Now supports the encoding type 'x-uue' for uudecoding. I think there are
                   2548:     mailers that use different names for the same encoding type so we better
                   2549:     watch out for them in the future...
                   2550:   
                   2551:   o Added the 'demimed' field to the body struct to keep track of 
                   2552:     header lines+ that have been RFC2047 converted already.
                   2553:   
                   2554:   o Kent Landfield sent me an interesting mail that showed me several weird
                   2555:     bugs in the MIME area.
                   2556:      A. The Quoted-Printable decoder bugged. A quick fix solved that.
                   2557:      B. The quoted printable decoder didn't support unlimited size of the line
                   2558:         the encoded text decodes into. I wrote a new function that seems to do
                   2559:         it properly.
                   2560:      C. Some important headers were not properly supported if they were split
                   2561:         up on several lines. I had to rewrite the header parsing system to make
                   2562:         this work. It now scans all headers and concatenate them into single
                   2563:         lines before any function is trying to parse or decode them.
                   2564:      D. It also showed a need for a uudecoder for the 'x-uue' encode type. This
                   2565:         is only noted for the future as I haven't written any decoder for this
                   2566:         format [yet].
                   2567:   
                   2568:   o decodeRFC2047 replaces the former RFC1522 function. I made it support
                   2569:     'encoded-words' anywhere in the line and several different ones on the
                   2570:     same line is now supported. The only flaw I'm still aware of now, is that
                   2571:     if there are two encoded-words next to each other, the result should not
                   2572:     show the spaces between them. My function unfortunately still does.
                   2573:   
                   2574:   o renamed decodeRFC1522 to decodeRFC2045.
                   2575:   
                   2576:   o decodeRFC1522 (quoted printable header decoding) didn't do well if the
                   2577:     ending ?= sequence was in the middle of the line. I think this function
                   2578:     will need more extensive testing.
                   2579:   
                   2580:   o Attached mails' headers (To:, From:, Date: and Subject:) are now shown
                   2581:     in the html.
                   2582:   
                   2583:   o Attached mails that contains attachments did force me to add a stack system
                   2584:     for the multipart boundary strings. Seems to work now. (Can't wait to see
                   2585:     an attached mail that contains an attached mail that contains ... )
                   2586:   
                   2587:   o strcpymax() introduced to prevent buffer overflows on extra-long headers
                   2588:   
                   2589:   o Lines starting with 'from ' messed up the parser pretty badly. It now
                   2590:     checks for 'From ' lines (case sensitive) with an empty preceding line
                   2591:     to split mails.
                   2592:   
                   2593:   o Now extracts attachments to separate binary files.
                   2594:   
                   2595:   o Supports multiple lined headers.
                   2596:   
                   2597:   o Supports quoted-printable and base64 encoded headers.
                   2598:   
                   2599:   o Supports base64 encoded text/plain
                   2600:   
                   2601:   o Rewrote the URL and email parsing to allow multiple URLs and email
                   2602:     addresses on each line.
                   2603:   
                   2604:   o Extended the original functionality to much better deal with MIMEd
                   2605:     mails and the standards from RFC 1521 and 1522. There are still flaws in
                   2606:     compliance with those but the majority of all mails using mimed texts
                   2607:     will be presented in a fairly decent fashion.

                   2611: 
                   2612:   o Fixed problem with 'From: ' header lines in messages with the
                   2613:     following format: "From: <email@address.com>" wherein the "name"
                   2614:     from the previous email message would be used instead of reverting
                   2615:     to the address itself.
                   2616: 
                   2617:   o URLs can now include ampersands (&) if they are preceded by question
                   2618:     marks (?) in the URL string.
                   2619: 
                   2620:   o Email messages with no Subject line no longer grab the previous
                   2621:     email's subject.
                   2622: 
                   2623:   o Reworked the order of output so that "message" links are always at
                   2624:     the top of the page in article pages and date/thread/subject/author
                   2625:     pages.
                   2626: 
                   2627:   o Now escape '%' in mail URLs.
                   2628: 
                   2629:   o Escape for '+' was wrong, changed to '%2B' (was '%22').
                   2630: 
                   2631:   o Updated replace() function to recurse on 'afterstring' variable
                   2632:     rather than the whole 'newstring'.  More efficient and allows '%'
                   2633:     escaping.
                   2634: 
                   2635:   o config.h: Added configuration option for SHOW_MESSAGE_LINKS which
                   2636:     turns all message headers and footers off (except for the links to
                   2637:     the date, subject, thread and author pages).  SHOW_MESSAGE_LINKS
                   2638:     overrides the setting of SHOWREPLIES.
                   2639: 
                   2640:   o print.c (writearticles): Removed use of currentemail, currentid,
                   2641:     and currentsubject by forcing use of email2, msgid2, inreply2,
                   2642:     subject2, and name2 when calling struct.c (hashreplylookup).  This
                   2643:     was needed after I rearranged the order in which articles were
                   2644:     printed.
                   2645: 
                   2646:   o string.c (convurls): Added code in two locations for the 
                   2647:     Message-Id code segment to recurse on the remaining portion of the
                   2648:     line being processed.  Each Message-Id found forces a return from
                   2649:     convurls() after a recursive call.  This prevents infinite recursion
                   2650:     (a Bad Thing generally speaking).  Note: we assume that Message-Ids
                   2651:     and URLs/email addresses do NOT appear in the same line.
                   2652: 
                   2653:   o string.c (convurls): Changed format string from "%.3d" to "%.4d".
                   2654:     Fixed major bug in outputting links for Message-Ids.
                   2655: 
                   2656:   o string.c (convurls): Fixed assumption in code for identifying
                   2657:     Message-Ids that there was only one Message-Id per line.  We now
                   2658:     stop gobbling up text used for a link with a space (' ') or a tab
                   2659:     ('\t').
                   2660: 
                   2661:   o string.c (convurls): Added int got_question_mark in URL processing
                   2662:     code to permit an ampersand ('&') in a URL provided it comes after a
                   2663:     question mark in the same URL (a GET method with POST data).  Added
                   2664:     one line of code and changed another to accomplish this.
                   2665: 
                   2666:   o string.c (convurls): Added code to check whether the next item to
                   2667:     URL-ize is an email address (containing an at sign, '@').  If it is,
                   2668:     we break out of the URL for loop and go process the email address.
                   2669: 
                   2670:   o parse.c (loadoldheaders): Modified initial fgets() call to skip any
                   2671:     non-comment lines (i.e. "<html>" and "<head>").
                   2672: 
                   2673:   o string.c (makemailcommand): Added code to escape percent signs 
                   2674:     ('%') when escaping spaces (' ') and plus signs ('+').  Percent 
                   2675:     signs must be escaped first since other escape sequences use the
                   2676:     percent sign followed by a two-digit hexadecimal number.  We're now
                   2677:     a little more MIME-compliant.
                   2678: 
                   2679:   o string.c (replace): Changed the replace() function to recurse only
                   2680:     on the 'afterstring' portion of the URL instead of the whole rebuilt
                   2681:     URL.  This is both more efficient and prevents infinite recursion
                   2682:     problems when escaping percent signs ('%') with '%25'.  
                   2683: 
                   2684:   o string.c (makemailcommand): Fixed escape sequence for plus signs
                   2685:     ('+') from '%22' to '%2B'.
                   2686: 
                   2687: LOTS of other small patches from lots of other helpful people. I hope to 
                   2688: be able to more accurately list them in the final 2.0 version.
                   2689:

                   2691: =================================
                   2692: 
                   2693:   o Header corrections made, 
                   2694: 
                   2695:   o all current memory leaks plugged, 
                   2696: 
                   2697:   o variable initialization corrected, 
                   2698: 
                   2699:   o expanded response message recognition, 
                   2700: 
                   2701:   o fixed many threading related bugs. 
                   2702: 
                   2703:   o Restructuring directory layout for ease of support and to 
                   2704:     make adding utilities easier. 
                   2705: 
                   2706:   o Added additional archive utilities. 
                   2707: 
                   2708: 1.03b1  4/6/97 - Kent Landfield
                   2709: ================================
                   2710: 
                   2711:   o Corrected memory leaks, 
                   2712: 
                   2713:   o cleaned up HTML produced, 
                   2714: 
                   2715:   o ran purify, lint and insight and cleaned up output.  
                   2716: 
                   2717:   o Added the ability to customize header/footers via crude means
                   2718:     but hey, it works.
                   2719: 
                   2720: 1.02  8/1/94 - Kevin Hughes
                   2721: ============================
                   2722:         Fixed configfile problem, different usage() output, days[] space
                   2723:         fix, NODATE, stripzone() fix, insig fix, SHOWBR, SHOWHR, IQUOTES,
                   2724:         THRDLEVELS.
                   2725: 
                   2726: 1.01  7/29/94 - Kevin Hughes
                   2727: ============================
                   2728:         Printfooter declaration, getdate() and timezone names changed
                   2729:         to avoid library conflicts. Bad #define fixed (null) bug.
                   2730: 
                   2731: 1.0   7/29/94 - Kevin Hughes
                   2732: ============================
                   2733:         Configuration file, logic fixes, better "re:" stripping,
                   2734:         name tags, default index.html (HM_DEFAULTINDEX), default
                   2735:         directory name can be mailbox name, mailto: fix, better dates,
                   2736:         better error messages, numbered files are padded to four digits,
                   2737:         headers are always in <pre>, next in thread, maybe in reply and
                   2738:         maybe reply, MAILCOMMAND, EURODATE, commented source, chmods only
                   2739:         new files, <html>, custom mail command variables.
                   2740:

                   2751:         Hypermail rewritten in C. Because the source is so new and
                   2752:         relatively untested, it's still considered to be in beta
                   2753:         until feedback from users is received.
