Bug List
------------------------------------------------------------------------
Version:	2.4.9, and earlier
Problem:   	Links to thread index from message page do not
		link to the correct thread index page when MULTIPG
		and TREVERSE is active.
Solution:	OPEN: The problem is that a listing for a message
		in a thread index is not "fixed" due to how threads
		are organized.  Non-related messages can move the
		location of a message listing, but currently MHonArc
		is unable to detect this.  A possible solution is
		to compare old ordinal location with new ordinal
		location for each message.  If different, see if new
		position cause message to move to another index page.
		If so, mark message to be edited.  This kind of check
		would cause a performance hit, but it may be
		unavoidable inorder to fix the problem.
Version Fixed:	OPEN
------------------------------------------------------------------------
Version:	2.4.5 - 2.4.9
Problem:   	Numerous '$' characters are scattered throughout
		archive pages.
Solution:	This problem can occur with a bad VARREGEX resource
		setting, or if set to the empty string.  mhrcfile.pl
		updated to only honor a VARREGEX setting if it is
		non-blank.  It is still up to the user to be extremely
		careful when setting this resource.  A big warning
		has been added to the VARREGEX resource reference
		page about the usage of the resource.
Version Fixed:	2.5.0b
------------------------------------------------------------------------
Version:	2.4.9, and earlier
Problem:   	Default value of TSLICE resource was "0:0".
Solution:	The docs say the default should be "0:4", so code
		fixed in mhinit.pl to reflect docs.  Note, existing
		archives that used the default value will have 0:0
		and would require an explicit setting of TSLICE to
		correct.  Fixed default will only affect new archives.
Version Fixed:	2.5.0b
------------------------------------------------------------------------
Version:	2.4.9, and earlier
Problem:   	M2H_RCFILE envariable setting had no affect.
Solution:	Bug introduced when multiple rcfiles could be
		specified on the command-line.  Fixed in mhinit.pl.
Version Fixed:	2.5.0b
------------------------------------------------------------------------
Version:	2.4.9
Problem:   	Image URLs in HTML data are stripped out.
Solution:	Fixed in mhtxthtml.pl
Version Fixed:	2.5.0b
------------------------------------------------------------------------
Version:	2.4.8, and earlier
Problem:   	Default CHARSETCONVERTERS values for latin[1-6] charsets
		causing require error.
Solution:	This was supposedly fixed in 2.4.8 in mhinit.pl, but
		apparently was not.  The def-mime.mrc file in the
		example directory did have the correct mappings.
Version Fixed:	2.4.9
------------------------------------------------------------------------
Version:	2.4.8
Problem:   	MHonArc aborts with Perl syntax errors if mhnull.pl
		filter is loaded.
Solution:	Dump typo errors that should have been caught before
		release.  Syntax errors fixed in mhnull.pl.
Version Fixed:	2.4.9
------------------------------------------------------------------------
Version:	2.4.7, and earlier
Problem:   	Message with HTML content can cause perl to crash.
		Other symptom would be that a stale .mhonarc.lck
		directory would exist preventing further archive
		updates.
Solution:	There appears to be a bug in perl's regex engine.
		The fix was to change mhtxthtml.pl comment declaration
		removal expression into a simplier one that just
		munges (removes parts) to avoid crashes.
Version Fixed:	2.4.8
------------------------------------------------------------------------
Version:	2.4.7, and earlier
Problem:   	Prefixing second argument to $PGLINKLIST()$ with
		a 'T' cause no thread page links to be rendered after
		current thread index page.
Solution:	Fixed in mhrcvars.pl: Make sure to strip 'T' from
		both arguments before evaluating numeric values.
Version Fixed:	2.4.8
------------------------------------------------------------------------
Version:	2.4.7, and earlier
Problem:   	Default CHARSETCONVERTERS values for latin[1-6] charsets
		causing require error.
Solution:	Fixed in mhinit.pl (typo in library filename).
Version Fixed:	2.4.8
------------------------------------------------------------------------
Version:	2.4.6, and earlier
Problem:   	ADDRESSMODIFYCODE not stored in database.
Solution:	Fixed in mhdb.pl (a dumb typo)
Version Fixed:	2.4.7
------------------------------------------------------------------------
Version:	2.4.6, and earlier
Problem:   	TPARENT message specifier for applicable resource
		variables will cause a resource variable to expand
		to the empty string if there is no parent message
		to the current message.
Solution:	If there is no parent message, TPARENT resolves to
		to the current message.
Version Fixed:	2.4.7
------------------------------------------------------------------------
Version:	2.4.5, maybe earlier
Problem:   	Using message-ids with -rmm does not remove messages.
Solution:	Fixed in mhrmm.pl

Problem:   	<PRE> tags are printed when decoding ISO-2022-JP
		encoded header text.
Solution:	Fixed in iso2022jp.pl
Version Fixed:	2.4.5
------------------------------------------------------------------------
Version:	2.4.3, and earlier
Problem:   	Text/html filter died with a "Modification of
		non-creatable array" error when a relative URL
		exists in body data, but no base URL defined for
		the html data.
Solution:	Fixed in mhtxthtml.pl
Version Fixed:	2.4.4
------------------------------------------------------------------------
Version:	2.4.0 - 2.4.3
Problem:   	Error "Can't modify keys in scalar assignment" occurs
		when using older version of Perl 5.
Solution:	Later Perl 5 releases support keys operator as an
		lvalue to preallocate a hash.  Assignment put in
		an eval block to avoid program termination.
Version Fixed:	2.4.4
------------------------------------------------------------------------
Version:	2.3.0 - 2.4.3
Problem:   	Setting IDXSIZE < MAXSIZE for a single page index
		causes the generation of incorrect list entries and
		null list entries.
Solution:	Fixed in mhindex.pl
Version Fixed:	2.4.4
------------------------------------------------------------------------
Version:	2.4.3, and earlier
Problem:   	Using entity references within MONTHS, WEEKDAYS, et al,
		not supported and caused names to be incorrect.
Solution:	The semi-colon, ';', was treated as an undocumented
		list separator in resource files.  "Feature" removed.
Version Fixed:	2.4.4
------------------------------------------------------------------------
Version:	2.4.2
Problem:   	$*GMTDATE$ and $*LOCALDATE$ expand to the empty string
		if using default time format string settings.
Solution:	Fixed in mhtime.pl
Version Fixed:	2.4.3
------------------------------------------------------------------------
Version:	2.4.2, and earlier
Problem:   	Multipart processing is done inproperly if nested
		multiparts exist and "outer" multipart entity has a
		boundary which is a substring prefix of an "inner"
		multipart entity.
Solution:	Fixed in readmail.pl
Version Fixed:	2.4.3
------------------------------------------------------------------------
Version:	2.4.2, and earlier
Problem:   	Cid URL in multipart/related is not resolved if message
		part being referenced is at a higher "level" (due to
		nested multiparts) than the referrer.
Solution:	Fixed in readmail.pl
Version Fixed:	2.4.3
------------------------------------------------------------------------
Version:	2.4.2, and earlier
Problem:   	-tnosort and -tnosubsort should be -notsort and
		-notsubsort.  Also, bogus -tnoreverse and -notgziplinks
		options listed in -help message.
Solution:	Fixed.
Version Fixed:	2.4.3
------------------------------------------------------------------------
Version:	2.4.2, and earlier
Problem:   	Charset parameter value not properly extracted when
		no space after value and next parameter
		(Example: charset=us-ascii;name="file.txt").
Solution:	Fixed in mhtxtplain.pl
Version Fixed:	2.4.3
------------------------------------------------------------------------
Version:	2.4.1, and earlier
Problem:   	M2H_URL envariable does not properly affect the URL
		resource.  M2H_SORT does affect it.
Solution:	Fixed (typo).
Version Fixed:	2.4.2
------------------------------------------------------------------------
Version:	2.4.1, and earlier
Problem:   	%c does not work in time format resources.
Solution:	Fixed.
Version Fixed:	2.4.2

Solution:	Fixed.
Version Fixed:	2.4.1
------------------------------------------------------------------------
Version:	2.4.0
Problem:   	Default filehandle changed to STDERR after call to
		get_resources().  Can cause problems for Perl apps
		calling MHonArc via API.
Solution:	Fixed.
Version Fixed:	2.4.1
------------------------------------------------------------------------
Version:	2.4.0
Problem:   	MHonArc under BSD OS would go into Win/MS-DOS mode.
Solution:	Make check for "dos" platform stricter in osinit.pl.
Version Fixed:	2.4.1
------------------------------------------------------------------------
Version:	2.3.3
Problem:   	Duplicate message-ids in a message's reference list
		were not removed.
Solution:	Array changed to my() scope caused remove_dups()
		to not do anything (it takes a typeglob).  Array
		changed back to local().
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.0-3
Problem:   	TFIRST, TLAST, and PARENT arguments to resource
		variables always produced null values.
Solution:	Fixed.  Note, PARENT is now TPARENT to be consistent
		with other thread-related arguments.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.0-3
Problem:   	SUBJECTHEADER resource not printed when -savemem is
		used.
Solution:	Problem is due to the new resource variable handling
		in 2.3.  The solution is to support the editing of
		SUBJECTHEADER (and HEADBODYSEP) in existing message
		pages.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.3, and earlier versions
Problem:   	Multipart processing not done properly if boundary
		parameter not enclosed in quotes and is terminated
		by a semi-colon.
Solution:	Fixed in readmail.pl.
Version Fixed:	2.4.0

		having images inlined.
Solution:	Content-Disposition parsing fixed.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.3, and earlier versions
Problem:   	Clip length not handled properly in resource variables.
		Ie.  Characters that are translated into entity
		references are not handled properly when computing clip
		adjustment.  Incorrect clipping can occur.
Solution:	Fixed.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.3, and some possible earlier versions
Problem:   	MHonArc checking for writable OUTDIR in SINGLE mode.
Solution:	Fixed.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.3, and earlier
Problem:   	Default resource file not read if located in MHonArc
		lib directory.
Solution:	Fixed improper assumption of @INC setting.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.3, and earlier
Problem:   	TLIEND not generated at proper times when thread level
		goes beyond TLEVELS.
Solution:	A check is made in thread index printing to generate a
		TLIEND properly for TLITXT when deeper than TLEVELS.
Version Fixed:	2.4.0
------------------------------------------------------------------------
Version:	2.3.0-2.3.2
Problem:   	-otherindex and -perlinc command-line options do not
		work.  Using them has no affect.
Solution:	Subtle precedence issue in Perl variable operations;
		problem fixed.
Version Fixed:	2.3.3
------------------------------------------------------------------------
Version:	2.3.0-2.3.2
Problem:   	Resource variable expansion not working properly in
		MAILTOURL resource.
Solution:	Certain variables in read_mail_header() where put in
		my() declarations when they should stay as local()'s.
		Changed back.
Version Fixed:	2.3.3
------------------------------------------------------------------------
Version:	2.3.0-2.3.2
Problem:   	Next/previous message link resource variables are
		reversed when REVERSE is on.
Solution:	REVERSE check was left out in new v2.3 replace_li_var().
		Check added in.
Version Fixed:	2.3.3
------------------------------------------------------------------------
Version:	2.3.0, 2.3.1
Problem:   	Some resource variables (eg $SUBJECTNA$) expand to
		blank values when using -single.
Solution:	SINGLE mode sets @MListOrder and %Index2MLoc to support
		the new way in v2.3 replace_li_var() resolves resource
		variables.
Version Fixed:	2.3.2
------------------------------------------------------------------------
Version:	2.3.1 (maybe earlier versions also)
Problem:   	MHonArc does not handle message range specification
		with leading zeros in numbers in -rmm mode.
Solution:	int() is used within Perl's range operator to force
		the stripping of leading zeros.
Version Fixed:	2.3.2
------------------------------------------------------------------------
Version:	2.3.0
Problem:   	Attachments of the same type get written to the same
		filename.
Solution:	Another my/local gotcha.  Note, writing attachments
		has been redone so other filters besided mhexternal.pl
		can write data to files.
Version Fixed:	2.3.1
------------------------------------------------------------------------
Version:	2.0.0 - 2.2.0
Problem:   	A bogus TCONTBEGIN may get printed at the beginning
		of a thread index page.  Most common when TREVERSE
		specified.
Solution:	@TListOrder now serves as the basis for list iteration
		when printing a thread index page instead of the list
		returned by t_sort_messages().  Note, old method may
		cause other minor errors in thread index page
		generation.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.2.0, 2.3.0 beta
Problem:   	Duplicate index list entries are generating for threads
		indexes generated via OTHERINDEXES with TREVERSE active.
Solution:	All key data structures are now reset when recomputing
		threads.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.2.0, 2.3.0 beta
Problem:   	Threads are not listed in reverse order when THREAD
		and TREVERSE are set for an OTHERINDEXES resource file.
Solution:	Thread data structures are now reset before each
		OTHERINDEXES index.  If an OTHERINDEXES resource file
		specified THREAD, than threads will be recomputed
		for the given index defined by resource file.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.3.0 beta
Problem:   	Mail addresses in message headers are not getting
		converted to mailto links.
Solution:	MHonArc still uses typeglobs for passing data around
		by "reference" (left-over from Perl 4 days).  One
		of the variables in the message header formatting
		routine was changed back to a local() variable to
		supporting passing it via a typeglob sub-routines.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.3.0 beta
Problem:   	Cannot copy file error occurs during installation when
		copy documentation to destination location.
Solution:	Updated install.cfg to reflect file changes to
		documentation.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.3.0 beta
Problem:   	Author index generated via the OTHERINDEXES resource
		does not list messages in proper order.  Other main
		indexes generated via OTHERINDEXES may suffer the
		same problem.
Solution:	The write_main_index() did not reset %Index2MLoc
		properly, affecting resource variable resolution.  If
		@MListOrder is recomputed, %Index2MLoc will be
		redefined.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.3.0 beta
Problem:   	PG(PREV) and PG(TPREV) did not resolve to IDXFNAME and
		TIDXFNAME, respectively.  They resolved to (T)IDXPREFIX
		with the page number 1.
Solution:	Simple fix to page number check.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.2.0, 2.3.0 beta
Problem:   	Messages grouped under wrong date in date-based index.
Solution:       The problem is related to a descrepency of GMT time
		and local time, and what time format is being used
		in the DAYBEGIN resource.  The resource USINGLOCALTIME
		has been added to give the choice betweem GMT or
		local time for determining day groups.
Version Fixed:	2.3.0
------------------------------------------------------------------------
Version:	2.2.0
Problem:   	Get "times not implemented at mhamain.pl line 74" error
		on Win32 systems.
Solution:	Call to times is put in an eval block.
Version Fixed:	2.3.0 alpha
------------------------------------------------------------------------
Version:	2.2.0
Problem:   	When a message that gets automatically deleted via
		MAXSIZE or the message expiration, related message
		sometimes do not get update -- causing messages to
		have links to non-existent messages.  Problem manifiest
		when main sort option is not by date.
Solution:	Automatic message deletion now properly marks related
		message by specified main sort option.
Version Fixed:	2.3.0 alpha
------------------------------------------------------------------------
Version:	2.1.2
Problem:   	The @TListOrder array is empty in .mhonarc.db when
		MULTIPG is set.  This may cause some messages not
		getting properly updated when new messages are added.
Solution:	Removed use of splice on @TListOrder when MULTIPG.
		Now, array slices are used so @TListOrder is preserved.
Version Fixed:	2.2.0
------------------------------------------------------------------------
Version:	2.1.2
Problem:   	Convert ISO-2022-JP messages can generate "Out of
		Memory" errors.
Solution:	The cleanup of mhtxtplain.pl's iso-2022-jp code
		introduced a bug that caused an infinite loop and
		to gobble memory until it ran out.  The fix was
		straight-forward.
Version Fixed:	2.2.0
------------------------------------------------------------------------
Version:	2.1.2
Problem:   	Quoted text that is broken due to maxwidth setting of
		the mhtxtplain.pl filter did not have the quote
		character prepended to broken the text.
Solution:	A regex updated to dealing with a leading space before
		quote character.
Version Fixed:	2.2.0
------------------------------------------------------------------------
Version:	2.1.1
Problem:   	Documentation of MAILTOURL incorrectly states that
		the $TO$ resource variable is the value of the
		To: message header field.
Solution:	Fixed documentation to state that $TO$ represents the
		address being hyperlinked.
Version Fixed:	2.1.2
------------------------------------------------------------------------
Version:	2.1.1
Problem:   	Attachments saved to files with spaces in filename
		(due to "usename" option set to m2h_external::filter),
		will cause anchors to the attachments in the HTML
		message contain spaces.
Solution:	Fixed m2h_external::filter to escape special characters
		in the URL linking to the external file.
Version Fixed:	2.1.2
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Message with dates after 2037, or before 1970, will hang
		MHonArc, not get processed, or listed in wrong order.
Solution:	The problem is that Perl's timelocal.pl library cannot
		handle dates out of those ranges (same applies to
		Time::Local).  Since get_time_from_date() is the only
		routine require the services of timelocal.pl, the
		routine will generate a warning of bad years and use
		the current year.
Version Fixed:	2.1.1 (Work-around)
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Anchors to attachments in a message converted via
		SINGLE do not contain OUTDIR if OUTDIR is specified.
		OUTDIR may want to be set to all attachments to be
		contained in a separate directory from the converted
		message.
Solution:	mhexternal.pl now checks $SINGLE variable set by the
		main code during startup.  If set, the value of
		$OUTDIR is prepending to any hrefs to external files.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	February is misspelled "Febuary" in mhtime.pl.
Solution:	Change the spelling so its correct.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Lowercase timezones in dates are not recognized.
Solution:	Code modified to convert zones to uppercase when
		performing hash lookups.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Specified filenames of attachments sometimes have a
		';' appended when utilizing the "usename" option is
		set for mhexternal.pl.
Solution:	Fixed MAILhead_get_disposition() in readmail.pl to
		strip off ';' parameter separator.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Specified filenames with spaces of attachments are not
		recognized properly.  Filename gets truncated to first
		occurance of a space.
Solution:	Fixed MAILhead_get_disposition() in readmail.pl to
		to handle filenames with spaces.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	The HTMLEXT resource does not affect the numbered index
		page filenames of a MUTLIPG archive.
Solution:	write_main_index() and write_thread_index() fixed.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Anchor text of MAILTOURL links is translated to URL
		escaped text.
Solution:	mailUrl() routine fixed.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Message 0 could not be deleted if specified with more
		than one 0 (eg: 00000);
Solution:	rmm() routine fixed.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	SUBJECTHEADER does not get stored in the db.
Solution:	output_db() routine updated to save SUBJECTHEADER.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Empty links can be created if there is no "From" defined
		for a message and it is used as link text.
Solution:	Use 'No Author' as "From" if not defined.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:	If a user defined resource variable is a string that
		Perl interprets as a false value, it will not be used.
Solution:	Changed code to used define() function in
		replace_li_vars().
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.1.0
Problem:   	Expired messages are not removed when a the main index
		is not sorted by date.
Solution:	Always sort message by date when doing expire check.
Version Fixed:	2.1.1
------------------------------------------------------------------------
Version:	2.0.1
Problem:   	An undefined subroutine error occured during an
		RMM operation when there are messages with non-ASCII
		encodings in message headers.
Solution:  	Proper libraries are now loaded for RMM operations.
Version Fixed:	2.1.0
------------------------------------------------------------------------
Version:	2.0.1
Problem:   	Subjects using the "... -Reply" convention started
		a new thread.
Solution:  	Fixed typo in regexp.
Version Fixed:	2.1.0
------------------------------------------------------------------------
Version:	2.0.1
Problem:   	Nested anchor markup occurs on index pages when
		a message's subject contains a URL and the subject
		is used to link to the message page.
Solution:  	Replaced default routine that converts subject text
		to HTML to a routine that does not hyperlink URLs.
Version Fixed:	2.1.0
------------------------------------------------------------------------
Version:	2.0.0
Problem:   	Bogus empty entry shows up in the database.  Bogus
		entry appears if a duplicate message is detected.
		Potential visible problems of bogus entry are: mailto
		links in headers corrupted; a blank listing in the
		index.  Maybe other potential problems.
Solution:  	There is a bug in some versions of Perl where a
		hash key gets added invalidly.  The section of code that
		this occurs has been modified to avoid the problem.
		For existing databases with a bogus empty entry,
		MHonArc now removes any empty key entries.
		However, it is recommed to rebuild the archive.
Version Fixed:	2.0.1
------------------------------------------------------------------------
Version:	2.0.0
Problem:   	Index pages are not properly updated if zero messages
		are in the archive (like through the -rmm option).
		Even -editidx cannot cause a proper update.
Solution:  	Page count was set to zero when no messages exist.  This
		caused problems in conditional checks in the write index
		routines.  To fix, page count is forced to 1 if their
		are no messages.
Version Fixed:	2.0.1
------------------------------------------------------------------------
Version:	2.0.0 beta 3
Problem:   	Index pages with last page links are not updated
		when a new page is added.
Solution:  	All index pages are regenerated if a new page
		is added.
Version Fixed:	2.0.0
------------------------------------------------------------------------
Version:	2.0.0 beta 3
Problem:   	"-idxsize 0" does not give unlimited page size.
Solution:  	Problem fixed and now works as documented.
Version Fixed:	2.0.0
