Change History for MHonArc ========================== Change history for MHonArc. Changes listed are brief. Consult the documentation for further information/clarification. It is possible that not all changes are documented here. MM/DD/YYYY ======================================================================= ####################################################################### ======================================================================= 04/13/2001 (2.4.8) o Added the following resources: KEEPONRMM Do not remove message files from disk when messages are removed from the archive. o m2h_text_plain::filter now uses CHARSETCONVERTERS for translating text data with a specified charset parameter. The only exception is iso-2022-jp, which is handled directly to properly support nourl flag. o m2h_external::filter new arguments: excludeexts=ext1,... A comma separated list of message specified filename extensions to exclude. I.e. If the filename extension matches an extension in excludeexts, the content will not be written. The return markup will contain the name of the attachment, but no link to the data. This option is best used with application/octet-stream to exclude unwanted data that is not tagged with the proper content-type. The m2h_null::filter can be used to exclude content by content-type. o m2h_null::filter will now output a one line description of the excluded content. This is so the reader knows that there was message content not saved within the archive. o m2h_text_plain::filter new arguments: usename If extracting uuencoded data, the filename specified should be used. o m2h_text_html::filter new arguments: allowcomments Preserve any comment declarations. Normally Comment declarations are munged to prevent SSI attacks or comments that can conflict with MHonArc processing. Use this option with care. (NOTE: Comment declarations were completely stripped before, but the regex used was known to crash perl on large comment declarations, so a simplier expression is now used to modify comment declarations to prevent possible attacks.) Bug Fixes --------- See BUGS. ======================================================================= 10/28/2000 (2.4.7) o Added the following options to m2h_text_plain::filter: attachcheck Honor attachment disposition. By default, all text/plain data is displayed inline on the message page. If attachcheck is specified and Content-Disposition specifies the data as an attachment, the data is saved to a file with a link to it from the message page. htmlcheck Check if message is actually an HTML message (to get around abhorrent MUAs). The message is treated as HTML if the first non-whitespace data looks like the start of an HTML document. o FROMFIELD resource default value is now: from:mail-reply-to:reply-to:return-path:apparently-from: sender:resent-sender The change is the addition of "mail-reply-to." o Added the following resource variables: $MSGTORDNUM$ Ordinal number of message in current thread. o Added the following resource variable message specificiers: TEND Last message of current discussion thread. TTOP Top/root message of current discussion thread. o Changes to readmail.pl: - %Cid hash keys are now URLs. Content-Ids are denoted as "cid:..." Hash also contains Content-Location values of message parts. This allows filters (like the HTML filter) to check for external URL references where the data for the reference is included with the message. - More robust handling of malformed multipart messages. o The null filter is applied to application/ms-tnef by default. o Lowercase tag names are now used in default resource values that contain HTML markup. o Bug fixes to the documentation. Bug Fixes --------- See BUGS. ======================================================================= 04/24/2000 (2.4.6) o Stricter check is made when decoded quoted-printable data. An escape sequence is only converted to a raw character if a it is a valid escape sequence. I.e. Any '=' not followed by two hexadecimal characters is left as-is. o Call to Digest::MD5::md5_hex() wrapped in eval block in case of bad installations of Digest::MD5 module. Bug Fixes --------- See BUGS. ======================================================================= 02/14/2000 (2.4.5) Enhancements/Changes -------------------- o Following changes to m2h_text_html::filter: - All comment declarations are removed. This avoid potential SSI attacks and declarations that may conflict with MHonArc. - Additional tags have been added to the to-strip list to avoid potential client-side scripting attacks. See MIMEFILTERS docs for list. - Added "nofont" option to strip out any tags. o Added application/x-bzip2 to known mime types (mhmimetypes.pl). o Simple modification to get_time_from_date() in mhutil.pl to handle abhorrent case of message date using a 2 digit year. o Under VMS, the default lock file name has been changed to "mhonarc_lck" for directory based locking will work. o mhonarc::htmlize/entify now translates the double-quote character (") to ". o Added VARREGEX resource to allow customization of resource variable matching. Mainly for use with resource files written on multibyte charsets like SJIS. Use with caution. Bug Fixes --------- See BUGS. ======================================================================= 10/01/1999 (2.4.4) Enhancements/Changes -------------------- o Added the following resources: MIMEDECODERS Content-Transfer-Encoding decoding functions. o Added the following resource variables: $PGLINKLIST$ Print out a list of index page links. o New content filter for message/external-body. o Message/delivery-status content handled by mhtxtplain.pl o Support for "Zone[+-]DDDD" timezone specification. o MAILparse_parameter_str() function added to readmail.pl. Function supports parsing parameter value strings with support for RFC 2184 extensions. Function added to provide support for message/external-body filter. Bug Fixes --------- See BUGS. ======================================================================= 08/15/1999 (2.4.3) Enhancements/Changes -------------------- o Added the following resources: POSIXSTRFTIME Use POSIX::strftime() or not for processing time format strings o The "latin[1-6]" character sets defined in the default value of CHARSETCONVERTERS. iso8859::str2sgml modified to use proper iso8859 map for specified latin[1-6] specification. o The text/html filter now strips out scripting markup by default. To allow scripting markup to be preserved, the "allowscript" option can be used. o Unknown media-types are now treated as application/octet-stream, which will invoke the application/octet-stream filter. Because of this, an explicit entry for application/octet-stream has been added to the default value of MIMEFILTERS. o If in a multipart/alternative entity, and no known media-types exists, the last part is treated as application/octet-stream. Bug Fixes --------- See BUGS. ======================================================================= 08/11/1999 (2.4.2) Enhancements/Changes -------------------- o Added the following resources: STDIN Source for standard input o Added the following resource variables: $ENV$ Print an environment variable o Added support for decoding uuencoded data within text messages in mhtxtplain.pl. Decoding activated via the "uudecode" option. o For processing time format strings, POSIX::strftime() is used, if available. If not, MHonArc implementation is used. o The default value of FROMFIELDS now includes "return-path". o Description section moved before Options section in -help message. Bug Fixes --------- See BUGS. ======================================================================= 07/25/1999 (2.4.1) Enhancements/Changes -------------------- o Added the following resources: MSGEXCFILTER Perl expressions for excluding messages from archive. SAVERESOURCES Flag if resource values should be saved in database. o Added the following resource variables: $HTMLEXT$ Value of HTMLEXT resource. o Documentation corrections an additions. o Use of typeglobs removed from mhdb.pl. o mhtime.pl explicitly defined in mhonarc package. Bug Fixes --------- See BUGS. ======================================================================= 06/25/1999 (2.4.0) Enhancements/Changes -------------------- o Added the following resources: ADDRESSMODIFYCODE Perl expressions to apply to addresses during message header conversion. CHECKNOARCHIVE Check "no archive" flag in messages. LOCKMETHOD The type of archive locking performed. SPAMMODE Perform actions to deter email address harvesters. SSMARKUP Markup at the *very* beginning of any generated page. STDOUT Destination of stdout messages/data. STDERR Destination of stderr messages/data. SUBJECTTHREADS To check, or not to check, subjects when computing threads. o Added the following resource variables: $FROMADDRNAME$ Username portion of From email address. $FROMADDRDOMAIN$ Domain portion of From email address. $TOADDRNAME$ Username portion of an email address (applicable in MAILTOURL only). $TOADDRDOMAIN$ Domain portion of an email address (applicable in MAILTOURL only). o A new utility program: mha-decode. The program functions as a MIME message decoder. Can be used against mail folders or single messages. o The "PARENT" argument to applicable resource variables is now called "TPARENT". This change should not affect anyone since the "PARENT" argument did not work properly in previous releases. o SUBJECTHEADER and HEADBODYSEP resource changes will now affect existing messages that are edited during normal operations or via EDITIDX. Note, messages created from old versions of MHonArc may not be affected. o The default TIMEZONES settings now has a more complete list. o Timezone acronym settings now support [+-]HHMM specifications. o Support for ISO-2022-JP encoded strings in message headers is now supported. It does assume that HTML viewer supports ISO-2022-JP. o If Digest::MD5 is installed, md5_hex() will be used to create message-ids for messages without message-ids. This allows MHonArc to ignore non-message-id archived messages in ADD mode. The MD5 digest is computed only on message header for efficieny. If Digest::MD5 is not installed, a message-id will still be assigned if none present, but MHonArc will not be able to detect if message has already been archived in subsequent ADD operations. o Text/html filter supports the "noscript" option. If specified, any script-related markup will be removed. This provides added security to avoid sites being compromised with foreign client-side scripting. o Added the following options to mhexternal.pl (the save-to-file filter): forceattach, forceinline, and inlineexts. o Recognize mailing list headers as defined by RFC 2369 and hyperlink URLs listed. o If no boundaries exist in a multipart message (even though a boundary is defined in the header), MHonArc will treat the entire body as the first part. This prevents "unable to process" warnings. o The "" is now inserted between the message header and body. Helps in the building of some search indexes to restrict searches on message data. o Many resource settings are no longer stored in database if the resource is the default value. Save some disk space and allows resources to self adjust when a dependent resource is changed. o The text/plain filter in mhtxtplain.pl has the following enhancements: - Check for charset to control character conversion. - Integrated iso-2022-jp filter (keys off charset) - Filter option "quote" cause quoted text in message to be italicized. - Filter option "asis" defines a list of charsets to not convert to sgml entitites. Example usage: asis=iso-8859-1:iso-8859-2 o mhtxt2022.pl has been removed since the code has been integrated into mhtxtplain.pl. o Resource file elements that have textual content (ie. no line oriented content) can specify the "chop" attribute to have the last end-of-line stripped from the content. Example usage: [Next] o Fixed bug in creating links of message-ids. Mhonarc blindingly made links of message-ids when editting messages w/o consideration that the message-ids may already be linked. This caused markup like the following to occur: ...... Browsers handle the invalid markup with no problems, causing the bug to go unnoticed for a long time. Now, only new added message-ids are scanned for when creating links. o $readmail'FieldSep should now be used instead of $FieldSep for separating duplicate fields in a parsed message header. o The -scan output now prints a 4 digit year. o Bogus space no longer appears in subjects and dates. o Outdir permissions are not checked if -single specified. o Some internal changes to how data is stored in databases (needed for 1522 support). v2.0 will automatically modify 1.x databases to the 2.0 format. o The -single option utilizes the same mail output routine utilized by regular archive processing. o MhonArc will now handle numbers with leading zeros when the -rmm option is specified. o New resources: CHARSETCONVERTERS - Specify character set filters CONLEN - Honor content-lengths DECODEHEADS - Decode 1522 encoded data, set for decode only, as message headers are read (see note below) DEFINEVAR - Define resource variables DEFINEDERIVED - Define user defined derived file EXPIREDATE - Message cut-off date EXPIREAGE - Time in seconds from current if msg expires FIELDSBEG - Begin markup of converted mail header FIELDSEND - End markup of converted mail header FLDBEG - Begin markup of mail header field text FLDEND - End markup of mail header field text FOLREFS - Print links to explicit follow-ups & refs GMTDATEFMT - Format of $GMTDATE$ HEADBODYSEP - Markup between converted mail header & body IDXPREFIX - Prefix for multi-page main index filenames INCLUDE - Read resources from other files LABELBEG - Begin markup of mail header label LABELEND - End markup of mail header label LOCALDATEFMT - Format of $LOCALDATE$ MAIN - Create main index MHPATTERN - Expression for mesg files in a directory MODTIME - Set file times to message dates MONTHS - Full month names: EOL or ':' separated MONTHSABR - Abbrieviated month names: EOL or ':' separated MULTIPG - Create multi-page indexes NEXTPGLINK - Link to next page in main index NEXTPGLINK - Inactive link to next page in main index NOCONLEN - Ignore content-lengths NODECODEHEADS - Leave message headers "as is" when read (see note below) NOFOLREFS - Do not print links to follow-ups & refs NOMAIN - Do not create main index NOMODTIME - Do not set file times to message dates NOMULTIPG - Do not create multi-page indexes PREVPGLINK - Link to previous page in main index PREVPGLINKIA - Inactive link to previous page in main index SUBJECTHEADER - Markup for subject header in converted mail TIDXPREFIX - Prefix for multi-page thread index filenames TSUBLISTBEG - List begin in sub-thread TSUBLISTEND - List end in sub-thread TSUBJECTBEG - Begin markup for subject-based sub-thread TSUBJECTEND - End markup for subject-based sub-thread TSINGLETXT - Markup for mesg not part of a thread TTOPBEGIN - Begin for top of a thread TTOPEND - End for a thread TLINONE - Markup for missing message in a thread TLIEND - Thread idx list item end TNEXTBUTTON - Thread next button template TNEXTBUTTONIA - Inactive thread next button template TNEXTLINK - Thread next link template TNEXTLINKIA - Inactive thread next link template TNEXTPGLINK - Link to next page in thread index TNEXTPGLINKIA - Inactive link to next page in thread index TPREVBUTTON - Thread previous button template TPREVBUTTONIA - Inactive thread previous button template TPREVLINK - Thread previous link template TPREVLINKIA - Inactive thread previous link template TPREVPGLINK - Link to prev page in thread index TPREVPGLINKIA - Inactive link to prev page in thread index WEEKDAYS - Full weekday names: EOL or ':' separated WEEKDAYSABR - Abbrieviated weekday names: EOL or ':' separated NOTE 1522 processing is done when creating HTML output and the (relevant) data stored in the database stays in encoded form. The DECODEHEADS resource can be set to decode decode-only charsets when message headers are read. Hence, the decode-only charsets will be stored in decoded form. Regular 1522 processing is still done to still-encoded data when generating output. The default is NODECODEHEADS. o List of removed resources: NOTSUBSORT, TSUBSORT o New resource variables: (NOTE: Some variables are only valid in certain contexts) $FIRSTPG$ - Filename of first page of main index $IDXPREFIX$ - Prefix to main index pages' filenames $LASTPG$ - Filename of last page of main index $NEXTPG$ - Filename of next main index page $NEXTPGLINK$ - Link to next page of main index $NUMOFPAGES$ - Total number of pages in index $PAGENUM$ - Current page number of index $PREVPG$ - Filename of previous main index page $PREVPGLINK$ - Link to previous page of main index $TFIRSTPG$ - Filename of first page of thread index $TIDXPREFIX$ - Prefix to thread index pages' filenames $TLASTPG$ - Filename of last page of thread index $TNEXTBUTTON$ - Button for next mesg in thread $TNEXTFROM$ - From of next mesg in thread $TNEXTFROMADDR$ - From address of next mesg in thread $TNEXTFROMNAME$ - From name of next mesg in thread $TNEXTLINK$ - Link for next mesg in thread $TNEXTMSG$ - Next mesg filename in thread $TNEXTMSGNUM$ - Next mesg number in thread $TNEXTPG$ - Filename of next thread index page $TNEXTPGLINK$ - Link to next page of thread index $TNEXTSUBJECT$ - Next mesg subject in thread $TPREVBUTTON$ - Button for prev mesg in thread $TPREVFROM$ - From of previous mesg in thread $TPREVFROMADDR$ - From address of previous mesg in thread $TPREVFROMNAME$ - From name of previous mesg in thread $TPREVLINK$ - Link for prev mesg in thread $TPREVMSG$ - Previous mesg filename in thread $TPREVMSGNUM$ - Previous mesg number in thread $TPREVPG$ - Filename of previous thread index page $TPREVPGLINK$ - Link to previous page of thread index $TPREVSUBJECT$ - Previous mesg subject in thread o Removed resources: NOTSUBSORT, TSUBSORT o Some changes to default resource settings. o Reorganized code. Some new libraries have been created to help in maintenance. o Source code has been put under SCCS revision control. ======================================================================= 07/12/96 (1.2.3) o Extracted initialization of data structures into mhinit.pl. The file is just required from the main source. o Use q{} instead of qq{} when trying to read database file. Should fix require problem under MS-DOS. o Added comments at beginning of messages. May aid in database recovery techniques. o ';'s are now deleted in filenames in mhexternal.pl (applicable only when "usename" option specified) o Added recognition of '/' when converted e-mail addresses to mailto links in message headers. o Simple fix to mhtxt2022.pl for execution under Perl 5. ======================================================================= 04/18/96 (1.2.2) o Increased the speed performance of base64 decoding. Speed increase is much greater under Perl 4 than Perl 5. o Added -time option to print out total CPU execution time. Mainly used for debugging reasons (like checking on base64 decoding times). Time information is sent to standard error. o Added M2H_LOCKDELAY envariable and -lockdelay option. Either can be used to adjust the sleep time between attempts to lock the archive. o Added -force option to override a lock on an archive if attempts to lock fail. o Added image/x-bmp and image/x-pcx to the default supported MIME types. o Ignore "Sv:" at the beginning of subjects when sorting by subject. "Sv:" is Danish for "Re:". o Fixed bug in mhutil.pl where TIDXPGEND actually set TIDXPGBEG. o Dynamically define exclude_field routine after reading user options. exclude_field is utilized when formatting a message header in HTML. Defining the routine at run-time helps reduce the regular expression overhead the old version of the routine entailed. There should be an increase in overall execution time. ======================================================================= 03/22/96 (1.2.1) o Added support for x-uuencode content-transfer-encoding. o Added -locktries command-line option. o Added the resource variable $OUTDIR$. o mhexternal.pl filter will use the name parameter string on the content-type field as the anchor text to the file if there is no content-description. o application/x-patch is recognized and processed by the text/plain filter (mhtxtplain.pl). o Fixed bug in install.me and osinit.pl where setting $'PROG caused perl to terminate if $'DIRSEP was a backslash (occured under MS-DOS usage). o Fixed bug in install.me in the create_dir routine. If $DIRSEP was a backslash, the regular expression setting @a would cause perl to abort with an error. o Fixed database bug where the MIMEARGS resource setting was not being stored. o Fixed index listing bug where a reverse listing was not correct if an index size was specified less than the current size of the archive. ======================================================================= 03/01/96 (1.2.0) o Rewrote message parser routine so it will work under Perl 5 for multipart messages. The rewrite also allows some additional features that are mentioned below. o The -mbox and -mh options are no longer required. MHonArc will automatically determine which mode to operate in based upon the file arguments. Hence, one can specify MH folders and mailbox files on the same command-line. Both options are ignored if specified. o An HTML index of an archive contents can be generated to standard output (-genidx). o Message header lines not conforming to RFC 822 are ignored. (Eg: Those pesky "From " lines should not show up anymore -- please do not confuse this with the regular "From:" lines; note the colon vs the space). o New resources: BOTLINKS - May be used to completely customize the links at the bottom of messages. IDXPGBEGIN - Opening markup for main index page. Allows one to redefine opening HTML element, HEAD element, TITLE element, opening BODY element, etc. IDXPGEND - Closing markup for main index page. IDXSIZE - Set the maximum number of messages listed in index. This is different in MAXSIZE where MAXSIZE will remove older messages when the MAXSIZE limit is reached in the archive. MIMEARGS - Define arguments to filters MSGPGBEGIN - Opening markup for message pages. Allows one to redefine opening HTML element, HEAD element, TITLE element, opening BODY element, etc. MSGPGEND - Closing markup for message pages. NEXTBUTTON - Defines the 'Next' button. NEXTBUTTONIA - Defines the 'Next' button when it is inactive. NEXTLINK - Defines the 'Next' link. NEXTLINKIA - Defines the 'Next' link when it is inactive. NOTSUBSORT - Do not sort threads by subject. OTHERINDEXES - List other resource files defining other indexes to create when creating, or updating, an archive. PREVBUTTON - Defines the 'Prev' button. PREVBUTTONIA - Defines the 'Prev' button when it is inactive. PREVLINK - Defines the 'Prev' link. PREVLINKIA - Defines the 'Prev' link when it is inactive. TIDXPGBEGIN - Opening markup for thread index page. Allows one to redefine opening HTML element, HEAD element, TITLE element, opening BODY element, etc. TIDXPGEND - Closing markup for thread index page. TOPLINKS - May be used to completely customize the buttons at the top of messages. TSUBSORT - Sort threads listed by subject. o Removed resources: INDEXBL, INDEXFL, MBOX, MH, NEXTBL, NEXTFL, PREVBL, PREVFL, TINDEXBL, TINDEXFL Resource were removed because they were no longer applicable and/or have been superceded by other resources. MHonArc will still honor old resource settings (where applicable) of older archives and incorporate them into the new resource settings. o When specifying the resource file, mhonarc will now do the following to determine its location: 1. If its an absolute pathname, mhonarc uses it. 2. If it is a relative pathname, mhonarc checks for it relative to the current working directory. 3. Otherwise, mhonarc checks for it relative to location of the archive as specified by outdir. This resolution will allow you to place resource files with the archive if desired (can be useful when using the OTHERINDEXES resource element). o Because of the new resources available, many
's are no longer hard-coded and are controllable by resources.
's are still used in message pages to separate message data from mhonarc data. o Added resource variables: (NOTE: Some variables are only valid in certain contexts) $DDMMYY$ - Date of message in dd/mm/yy format $IDXSIZE$ - Max size of index list $MMDDYY$ - Date of message in mm/dd/yy format $MSGID$ - Message id $NEXTBUTTON$ - Next button markup $NEXTFROM$ - From field of next listed message $NEXTFROMADDR$ - From e-mail address of next listed message $NEXTFROMNAME$ - From name of next listed message $NEXTLINK$ - Next link markup $NEXTMSGNUM$ - Number of next listed message $NEXTSUBJECT$ - Subject text of next listed message $NUMOFIDXMSG$ - Number of messages in index list $PREVBUTTON$ - Previous button markup $PREVFROM$ - From field of previous listed message $PREVFROMADDR$ - From e-mail address of prev listed message $PREVFROMNAME$ - From name of previous listed message $PREVLINK$ - Previous link markup $PREVMSGNUM$ - Number of previous message $PREVSUBJECT$ - Subject text of previous listed message $YYMMDD$ - Date of message in yy/mm/dd format o Can specify a 'U' with variable length specifier to denote replacement string is to be used in a URL. Examples: $SUBJECTNA:40U$ $MSGID:U$ The 'U' causes the replace text to have special characters escaped as denoted by the URL spec. NOTE: Specify ":U" should NOT be used in the MAILTOURL resource; the variables will automatically be expanded according to the URL spec. Specifyind ":U" or a length specifier in the MAILTOURL resource will prevent mhonarc from detecting the variable. o New command-line options: -genidx - Generate HTML index of archive contents to stdout. -idxsize - Maximum number of messages shown in indexes -notsubsort - Do not sort threads listed by subject. -savemem - Write message data while processing -tsubsort - Sort threads listed by subject. o The library mhtxt2022.pl has been added that provides a filter to process ISO-2022 (Japanese) encoded mail messages. See mhtxt2022.pl on how to hook it in. o The mhexternal.pl filter by default ignores any filename specification in the message for creating derived files. This avoids name conflicts and security problems. The "usename" filter option may be used to override this. o Mime filters are now called with two additional arguments: $converted_data = &function( $header, *parsed_header_assoc_array, *message_data, $decoded_flag, $optional_filter_arguments); The $decoded_flag is set to 1 if the *message_data has been decoded. $optional_filter_arguments contains an optional argument string as determined by the filter. o Mime filters can now be registered for multipart types and message types. This allows one to override mhonarc's conversion of these types, and completely replace mhonarc's message->HTML conversion process. o Mime filters should now use $'FieldSep instead of $'X for accessing parsed message headers. o Mime filters can be registered for a base type. Ie. It is no longer required to explicitly list each possible subtype if a single filter is to be used for them all. Example: image/*:myfilter'imagefilter:myfilter.pl Registers "myfilter'filter" for all image data types, regardless of subtype. However, if an explicit entry exists for a subtype, then that filter is called. Example: image/*:myfilter'imagefilter:myfilter.pl image/gif:myfilter'giffilter:myfilter.pl "myfilter'giffilter" is called for all image/gif data. "myfilter'imagefilter" is called for all other image data. o A new resource, MIMEARGS, may be used to pass optional arguments to filters to control their behavior. The format of the argument string is controlled by the various filters. The arguments can be specified by a specific content-type, or for the filter routine in general. A content-type argument will be used over any arguments specified for a filter. Example usage: image/gif:inline usename m2h_external'filter:usename See the documentation for possible arguments to filters. o Installation program can now be invoked in batch mode. o Thread index properly includes docurl as main index. -nodocurl will prevent the inclusion as with the main index. o Fixed bug in mhtxthtml.pl on properly propogating a base URL to relative URLs starting with a "/". o Fixed bug where single quotes, and backslashed in keys of associative arrays in the database file were not getting escaped. o Fixed bug where spaces and special characters were not properly escaped in URL strings: spaces were left as-is, and special characters were deleted. o Removed illegal invocation choices in the Synopsis of the documentation. ======================================================================= 04/24/95 (1.1.1) o Fixed bug in -scan output where month in date was off by one. ======================================================================= 04/21/95 (1.1.0) o Made modifications to make MHonArc suitable to run under MS-DOS without modification. MHonArc will automatically detect if it is running under Unix or MS-DOS. o Added support for a thread index. MHonArc will create a complimentary index to the main index showing message threads. o Archive messages can be deleted. o A listing to stdout of an archives contents can be generated. o Maximum number of messages for an archive can be set. Older messages (based on sort method) are removed automatically during add operations. o MHonArc will now recognize if you try to add in a message that already exists in an archive. o The -editdx option will now also cause a updating of all mail messages. Guarantees resource changes to affect all messages. o Added the following resource file elements: MSGFOOT -- Footer text for converted messages MSGHEAD -- Header text for converted messages NODOC -- Do not put link to documentation NOTHREAD -- Do not create thread index TFOOT -- Text at bottom of thread index page THEAD -- Text at top of thread index page THREAD -- Create thread index TLEVELS -- Depth of thread listing TLITXT -- Template text for entry in thread index TIDXFNAME -- Thread index filename TINDEXBL -- Top button label in messages to thread index TINDEXFL -- Verbose label in message to thread index TTITLE -- Title of thread index page o Added the following command-line options: -maxsize -- Maxinum # messages in an archive -nodoc -- Do not put link to documentation -nothread -- Do not create thread index -rmm -- Remove messages from an archive -scan -- Listing of archive to stdout -thread -- Create thread index -tidxfname -- Thread index filename -tlevels -- Depth of thread listing -ttitle -- Title of thread index page o Added the following environment variables: M2H_MAXSIZE -- Maxinum # messages in an archive M2H_THREAD -- If non-zero, create thread index M2H_TIDXFNAME -- Thread index filename M2H_TLEVELS -- Depth of thread listing M2H_TTITLE -- Title of thread index page o Added the following variables for template resources (applicability of variables vary depending on the resource): $DOCURL$ -- URL to documentation $IDXFNAME$ -- Main index page filename $IDXTITLE$ -- Main index page title $NEXTMSG$ -- Next message filename $PREVMSG$ -- Previous message filename $PROG$ -- Program name $TIDXFNAME$ -- Thread index page filename $TIDXTITLE$ -- Thread index page title $VERSION$ -- Version number of the program o Added $FROM$, $MSGID$, and $SUBJECT$ variables to be used in the MAILTOURL resource. o The string `$$' in template resources will produce a `$' in the output. o Fixed problem with messages (with follow-ups) getting unnecessarily updated when messages are added to an archive. o Only a CR/LF, or LF, pair will terminate a message head. Before, MHonArc was terminating message heads when encountering an empty line or a line that only contained whitespace (which was incorrect behavior). o Fixed bug in mhexternal.pl dealing with the `name' parameter in the content-type field. Surrounding "s or 's were not being deleted causing filenames with quotes to be written. o mhexternal.pl: The head of a pathname in the `name' parameter in the content-type field is stripped off before writing the external file. I.e. Only the base filename is used. o Only one
after the H1 subject in messages will appear if no message header fields are printed. o Added recognition of the following content-types in mhexternal.pl: application/mac-binhex40 o Added a extras/ directory containing useful programs for MHonArc. See README in the directory for information on the programs contained in there. o To support -rmm, MIME filters now return an array. The first array value is the HTML for the message, and any other array values are filenames of files generated by the filter. This allows MHonArc to know of any extra files that must be deleted when a message is removed. o Some routines from the main mhonarc source file have been moved into a separate librarys: readmail.pl, mhdb.pl, mhutil.pl o The default URL to the documentation is now, http://www.oac.uci.edu/indiv/ehood/mhonarc.html The old URL, http://www.oac.uci.edu/indiv/ehood/mhonarc.doc.html is still valid. o There's probably other stuff, but I cannot remember. ======================================================================= 10/01/94 (1.0.0) o First release -- See RELNOTES about compatibility issues with mail2html. ======================================================================= ####################################################################### ======================================================================= Earl Hood, mhonarc@pobox.com @(#) CHANGES 01/04/13 12:33:07
