CHANGES for MHonArc <URL:http://www.oac.uci.edu/indiv/ehood/mhonarc.html> Revision history for MHonArc. Changes listed are brief. Consult the documentation for further information/clarification. MM/DD/YY ======================================================================= ####################################################################### ======================================================================= 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 <HR>'s are no longer hard-coded and are controllable by resources. <HR>'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: <mimefilters> image/*:myfilter'imagefilter:myfilter.pl </mimefilters> 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: <mimefilters> image/*:myfilter'imagefilter:myfilter.pl image/gif:myfilter'giffilter:myfilter.pl </mimefilters> "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: <mimeargs> image/gif:inline usename m2h_external'filter:usename </mimeargs> 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 <HR> 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, ehood@convex.com
