alterMIME CHANGELOG:
--------------------------------------------------------------------------
-Abbreviations Used:
DEV = This update was released as a DEVELOPMENT release of alterMIME
the change will be included in the next STABLE release as well.
STA = This update was released as a STABLE release of alterMIME
--------------------------------------------------------------------------
16 Nov 2008:
PLD-REL: 0.3.10
15 Nov 2008:
PLD-DEV:
Storing line delimeter in the alterMIME global struct. Saves
having to redefine/locate/check it all the time.
Added CR, CRLF and CRCR occurance counters in MIME_headers
Fixed up problem with AM_adapt_linebreak which caused
total stripping of delimeters
06 Nov 2008:
PLD-DEV:
Moved AM_globals structure to the mime_alter.h file so that
we can prepare for 0.4.x series which will provide an API
change forcing us to pass an AM_global struct into every
AM_* function. This will allow for multiple instances of
the alterMIME engine in a given process without clashing
issues of various global vars. Should have done this
years ago.
PLD-DEV:
Added an output filter AM_adapt_linebreak() to feed disclaimers
through so that their linebreaks match the last break type
detected with the FFGET() reading.
30 Oct 2008:
PLD-REL:
Cleaned up compile warnings (against Ubuntu's 8.10's gcc,
including fread/fwrite return values and the PLD_strlower()
signed parameter issues.
14 Oct 2008:
PLD-DEV:
qpe.c updated to handle broken Outlook issue.
07 Oct 2008:
-PLD:DEV:
Added altermime_status_flags global to allow for easy inspection of
the result of a disclaimer or xheader insertion run.
15 Aug 2008:
-PLD:DEV:
Extended the search depth of the segment-3+ insertion of disclaimers
allowing it to find potential HTML/Text disclaimer segments that may
have been burried deeper in a non-forwarded email. Insertion search
will terminate immediately if a RFC822 forwarded email header is
located.
20 Jul 2007:
-PLD:DEV:
Added closing of open file handles in AM nullify.
(this would cause files to be zeroed if one performed
an operation after nullifying attachments).
Fixed small memory leak from regex compilation in AM nullify.
13 Jul 2007:
-PLD:REL:
Release as 0.3.8
-PLD:DEV:
Updated ffget module.
Corrected some code where hard-coded buffer sizes were present rather
than properly referenced sizes.
09 Jun 2007:
-PLD:DEV:
Temporary file removal if insertion is aborted due to signed
email - Carlos Velasco
-PLD:DEV:
Added text/calendar detection to prevent mutating outlook
calendars (and others)
-PLD:DEV:
Preparing for STABLE release
09 Mar 2007:
-PLD:DEV:
Fixed bug that can cause crashing on QP decoding where the
charout size wasn't 1. Thanks to Yossi Gottlieb for suppling
the patch.
07 Mar 2007:
-PLD:DEV:
Added text/calendar detection, this allows us to implicitly
avoid adding disclaimers into these bodies by virtue of the
fact that alterMIME won't detect it as a "plain or HTML"
text body.
12 Feb 2007:
-PLD:DEV:
Patch applied for QP encoding problem of chars as hex.
(Patch provided by Julian Schneider)
30 Jan 2007:
-PLD:DEV:
Fixed missing boundary situation after BASE64 encoded
disclaimer insetion.
Fixed non-MIME BASE64 disclaimer insertion routines
(ie, for emails with only a single segment and no
boundary).
28 Jan 2007:
-PLD:DEV:
Added BASE64 _encoded_ disclaimer option so that
it's possible to insert a BASE64 pre encoded dislciamer
file into BASE64 bodies ONLY (ie, it won't be applied
to plain or QP encoded bodies).
--disclaimer-b64=
23 Jan 2007:
-PLD:DEV:
Added BASE64 disclaimer insertion routines (NAB)
Requires the use of --force-into-b64 to activate
Currently only works for text/plain and text/html
content-type segments. Using for other segment
types may cause unpredictable results (as it is the
results are not proven).
14 Jul 2006:
-PLD:DEV:
Rolled in new FFGET module with cleaner code.
Implemented FFGET_ftell / FFGET_fseek in the FFGET routines to
allow for better debugging and potential features in alterMIME
22 Jun 2006:
-PLD:DEV:
Fixed --help output to indicate that --remove=<filename regex>
is the correct notion, as apposed to the non-existant
"--remove-regex". Thanks to Alex Samorukov for pointing this out.
29 Mar 2006:
-PLD:REL:
Released as 0.3.7
27 Mar 2006:
-PLD:DEV:
Added SEGMENT 3 disclaimer insertion attempt to handle emails that
have both text and HTML representations of the email message.
02 Mar 2006:
-PLD:DEV:
Applied patch from Tim Jackson which solves a BASE64 induced
mail truncation if disclaimer insertion fails.
01 Mar 2006:
-PLD:DEV:
Added Quoted-printable encoding to disclaimers if required by
the transfer-encoding header of the MIME segment.
14 Feb 2006:
-PLD:DEV:
Fixed disclaimer insertion issue in emails with both HTML
and attachment.
27 Mar 2005:
-PLD:REL:
Release as 0.3.6
-PLD:DEV:
-Added -O2 option to Makefile for optimised binary
-Added --no-qmail-bounce parameter to alterMIME to allow people
to disable the email body search for files/attachments during
a remove/removeall operation.
-Added filename searching for the name= header parameters for
remove facility.
-Added headers-longsearch (qmail bounce) type detection for
remove facility.
24 Mar 2005:
-PLD:DEV:
-Fixed multipart[-insert] discrepency between help output and
actual functionality. --multipart-insert is the now correct
parameter.
-PLD:DEV:
-Fixed incorrect parsing of body data when a header could not
be inserted on the first segment, causing alterMIME to start
reading the body text as if it was header data. Thanks to
Pieter Vanmeerbeek for pointing this out and providing a
set of data that reliably produced the problem.
-PLD:DEV:
-Fixed help output to display 'suffix' rather than 'postfix' for
header alteration feature.
04 Feb 2005:
-PLD:DEV:
-Changed header insertion line from using a hard coded \r\n
to using the contents of the 'true blank' separator line.
(see AM_insert_Xheader)
20 Nov 2004:
-PLD:DEV:
-Fixed mistake in AM_add_disclaimer_cleanup(), where it
incorrectly tests the input file for stdin using
strcmp() causing alterMIME to not rename the new file.
04 Nov 2004:
-PLD:DEV:
Changed \n to \r\n delimeter for the X-header insertion routine
19 Oct 2004
-PLD:DEV:
Fixed up \r\n issues with UNIX created disclaimers showing up
fine in UNIX but as a single line in Windows. This one was for
Neil Wilson of ZA.
-PLD:DEV:
Added patch from Tim Bruylants to allow for forcing of
disclaimers in HTML MIME segments even if the segment doesn't
terminate with /body /html. The patch also permits the use of
disclaimers from STDIN (to STDOUT). Many thanks Tim.
Fixed misspelling of 'filname' in alterMIME help/usage
18 Sep 2004
-PLD:REL:
Release 0.3.5
-PLD:DEV:
Rewrite the AM_add_disclaimer() function, breaking it down into
smaller functions in an attempt to make it readable.
AM_add_disclaimer now calls;
AM_load_disclaimers() - Load the disclaimers required to insert.
AM_read_to_boundary() - read input file till a boundary is hit.
AM_add_disclaimer_no_boudary() - Insert into a non-boundary email.
AM_insert_disclaimer_into_segment() - Insert into a MIME segment
17 Sep 2004
-PLD:DEV:
Added content type and content transfer encoding types
to NOT insert disclaimers into. See the function AM_read_headers()
where the switch hinfo.content_type and .content_transfer_encoding
is listed.
This prevents some potential infinite loops when alterMIME tried to
read the data as headers, rather than as a MIME body.
Added BS_set_hold_limit() to limit the number of boundaries
held in the stack to a certain limit (in the case of alterMIME, 1).
This is done so that alterMIME doesn't try to traverse into
nested segments.
16 Sep 2004
-PLD:DEV:
Changed boundary tests from strstr() to BS_cmp()
Updated MIME_headers code to match the ripMIME engine
Fixed bug where some infinite loops occured while trying to
insert a HTML disclaimer
06 May 2004
-PLD:DEV:
Stopped alterMIME from inserting a disclaimer in a B64 encoded
main body.
10 Mar 2004
-PLD:REL:
Release 0.3.4
09 Mar 2004
-PLD:DEV: Fixed up header clobbering where the fields were ISO encoded
and duly un-encoded when filtered via alterMIME.
Thanks to Viktoras Rynkevicius for persuing this one.
16 Jan 2003
-PLD:DEV: Added initializers for some hinfo fields to pacify valgrind
-PLD:DEV: Added AM_done() function to clear any remaining disclaimer
malloc'd data produced from the strdup() call inside of
AM_set_disclaimer_*()
30 Nov 2003
-PLD:DEV: Implementing regex matching for attachment removal
14 Nov 2003
-PLD:REL: Released alterMIME 0.3.3
30 Oct 2003
26554
-PLD:DEV: Added x-header string filtering to prevent dubious strings
getting through, such as ones containing \n\r sequences or
0 length strings.
21 Oct 2003
-PLD:DEV: Reimplementing S/MIME detection (development)
26 Jun 2003
-PLD:DEV: Applied patch from Ludwig Pummer to fix up stdin/out streaming
for the --remove facility
11 Jun 2003
-PLD:DEV: Applied fix from Jorge Jimenez to resolve issues with HTML
disclaimer insertion in certain situations.
14 May 2003
-PLD: Fixed attachment-replace path inclusion into the MIME-headers
-PLD: Removed spurilous parameters off AM_add_disclaimer() call which
caused some segfault behavior in other external applications which were
using the alterMIME engine
04 May 2003
-PLD: Release as 0.3.1
28 April 2003
-PLD: replaced the attachment replacement code. Uses a very similar structure
to the code as used by the nullification/remove system [ with some minor
changes ]. There are still some outstanding issues, like how to cleanly
deal with the 'main' headers of each MIME, mostly in regards to the fact
that unlike the per-attachment headers, the main headers typically contain
a lot of other email-related information.
Overall the code works a lot better than the old one, despite the current
limitations.
Now, if an attachment is replaced, its old headers are also replaced.
The new headers are just Content-Type, Content-Disposition and
Content-Transfer-Encoding. There may be more headers added later
depending on the needs encountered.
Additionally, we can currently only add attachments in BASE64 encoding
format, I will extend this in the future to support QuotedPrintable
and plain-text.
27 April 2003
-PLD: Fixed header-alteration in Suffix mode problem where it would split
a doubleCR or singleCR line incorrectly, because it was looking for a LF
but didn't find one.
-PLD: Changed the nullification logic slightly so that the first MIME
segment can be 'nullified'. Rathern than being able to remove the
actual headers which specify the file details, it's been currently
chosen to clobber the filename in the headers by prefixing with either
a _ or X character and then proceeding to nullify the contents
-PLD: Nullification specification via --nullify= can be a regex expression.
This means that you can now remove multiple files, ie
--remove='\.exe$'
--remove-all has been retained, despite the fact that the feature can be
achived using --remove='.*'
26 April 2003
- Changed/replaced the AM_section1() call into AM_read_headers() in which
I then call MIMEH_parse_headers(), which does a vastly superior job of
detecting the /right/ headers.
- Replaced the AM_nullify_attachment() with a far more compact version
which does a far cleaner job of nullifying, removing the entire
attachment and headers [ except for attachments which are the entire
email body, in which case I have yet to still decide/workout how
best to handle the situation ]
25 April 2003
- Releasing as 0.2.2, this will be the last [ feature ] release for the
0.2.2 series. After this I will rip out a lot of the code dealing with
the header parsing and replace it with that which is now being used in
ripMIME - The new series will be 0.3.x
21 March 2003
- Added generic header replacement tool:
alterMIME now allows you to change headers [if they already exist] so
that you can do things like change subject headers.
A future extention will be to allow the modification of headers on all
the MIME segments rather than just the main headers.
To use:
--alter-header="header-you-want-to-change" --alter-mode=prefix|suffix|replace --alter-with="text to use"
--alter-mode= modes explanation:
prefix: prefixes the text defined with --alter-with before the current existing
text for the header
suffix: suffixes the text defined with --alter-with after the current existing
text for the header
replace: replaces all the currently existing header text with the text provided
by --alter-with
16 March 2003
- Released v0.2.1
23/02/2003
- Unified logging output routines ( all logging now goes via LOGGER )
- Added logging output mode option ( stdout / stderr / syslog )
- Added description of available options for alterMIME in verbose/help
mode
- Cleaned up altermime.c source code, placing all loose global vars into
single passed struct
22/02/2003
- Replaced strlower, XAM_strtok and zstr with a single module 'pldstr'.
- Added new modules filename-filter and libmimedecoders
- Added --disclaimer-html option which allows you to have a seperate
plaintext and HTML disclaimer
- Added --multipart option to force alterMIME to insert disclaimers into
the first level multipart block in an email, this means that you
can effective insert disclaimers into forwarded emails.
12/11/2002
- Released as 0.1.14
- Corrected a FFGET module bug which caused terminating lines without a \n or \r to
contain data from the previous line ( ie, there was no terminating \0 at
the string ending, thus the previous data in the buffer simply filled up
the rest of the buffer )
- Corrected the insertion of disclaimers in situations where a file attachment
ends without a boundary line.
- Corrected the insertion of disclaimers in situations where a single file is
attached with no email bodies.
12/05/2002
- Released as 0.1.13
- Cleaned up disclaimer insertion routines so that disclaimers are not inserted into
the incorrect MIME segment
- Used ccmalloc to test the allocation of memory when running --xheader or --disclaimer
, I'm pleased to say that both operations returned with no under or over use
of memory :-) ccmalloc is a great program tool, I highly recommend it for when
you're tracking down wierd bugs, often, just by cleaning up the memory spillages
you fix you bugs. - ccmalloc is by Armin Biere. (biere at inf.ethz.ch)
26/04/2002
- Released as 0.1.12
- Corrected segfault issue with x-header insertion, would occur once every 1000 or so emails
was caused by using snprintf() in alterMIME with one byte too high a buffer size value
this in turn cased the FFGET_FILE variable to be overwritten with a \0 byte causing
the program to crash on exit (which was rather interesting to watch).
- Improved the disclaimer insertion routines. Hopefully now it'll correctly put in the right
style of disclaimer (HTML or Plain) based on header information.
19/04/2002
- Corrected x-header insertion code, problem actually resided in the FFGET module
which was returning NULL on FFGET_fgets() one call too early.
06/03/2002
- Replaced AM_build_table() with a static decoding table at compile time
- Added FFGET library for file input and correct \n\r detections in headers
- Updated AM_insert_Xheader() routine.
22/10/2001
- Release 0.1.10
- Moved strlower() call into mime_alter codebase and
renamed it to AM_strlower. Also improved the speed
of the strlower call by removing the testing for
uppercase on each char.
- Makefile: Added strip command to make install
- mime_alter:AM_add_disclaimer: Added logic to deal with broken AOL emails [missing BODY tag]
- Thanks to Sean Kelly for supplying the mailpack.
21/10/2001
- Released 0.1.9
- Corrected boundary quotation closure issue.
20/10/2001
- Release 0.1.8
- Changed location detection algorithm for disclaimer insertion,
specifically to deal with emails which are [in effect] nested
one level down despite being new emails.
- No longer alters signed messages [for disclaimer addtion] without
being forced via --altersigned option
- Thanks to Raymond Bramwell for providing the assortment
of mailpacks showing up these intersting issues
17/10/2001
- Improved HTML disclaimer addition, prevented spurilous line addtion
in emails which had no additional attachments
15/10/2001
- Added ability to nullify all named attachments (feature Plead by Estaga)
- Improved disclaimer insertion technique so as not to break files
which didn't have </body> tag on a seperate line
- Made disclaimer addition remove the temp file after completion
09/03/2001
- Reworked replacement file section, making it buffer the headers before
writing out, this allows us to then change the headers to suit the
new file name without requiring two passes of the file.
- Got rid of the spurilous alterMIME decoding messages (why did I leave
them there in the first place!!#@$!!!
03/08/2001
