Dairiki (dairiki) Assigned to: Nobody/Anonymous (nobody) Summary: Coerce posts to plain text. Initial Comment: This patch adds the ability to have all posts to a mailing list forced into a MIME text/plain format. Many mailing lists have a charter which forbids binary and HTML posts to the list. This patch allows such a charter to be enforced is a maximally transparent manner. The feature is configurable on a per-list basis. If enabled, all posts to the list are run through a filter which: Squashes multipart messages into a single flat message (it picks the most plain-text-like alternative from multipart/alternative entities.) Converts 'text/html', 'text/enriched', and 'text/richtext' entities to 'text/plain'. Deletes cruft headers from content of type 'message/rfc822'. Deletes any uuencoded files from 'text/plain' entities. Entities of any other types are assumed to be binary attachements are are deleted. This patch is on mailman-2.0.3. ----------------------------------------------------------------------

Message: Logged In: YES user_id=45814 I don't have strong feelings, but my druthers would be to wait until 2.1 is officially designated "stable". A link from the wiki would be great! (There is/was already a link from the FAQ.) ---------------------------------------------------------------------- Comment By: Barry A. Warsaw (bwarsaw) Date: 2002-08-13 08:29 Message: Logged In: YES user_id=12800 Since this patch is against 2.0.x and since MM2.1 provides support for stuff like this, I'm inclined to close this patch. I'd be willing to add a link to this from the unofficial patches wiki. What do you think? ---------------------------------------------------------------------- Comment By: Seb Wills (sebwills) Date: 2002-02-23 08:20 Message: Logged In: YES user_id=467580 This patch seems to leave any preamble above the first part of a multipart message intact. Many mailers put blurb such as "This is a MIME-encoded message; you will need a MIME- aware mail client to see all of this message." here, which it makes no sense to reproduce after the mail has be coerced into plaintext. Looks like it's easy enough to change this behaviour by commenting out the line mimetools.copybinary(infp, outfp) # copy preamble from Mailman/FilteringMimeWriter.py ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-12-15 10:15 Message: Logged In: YES user_id=45814 Another bug fix. Lines which contain nothing but the word 'end' mysteriously dissapear. (Reported by David Gibbs.) The only changed file in Mailman/FilteringMimeWriter.py, I've attached the latest version of that file to this page. As usual, patches on mailman 2.0.8 are also attached. Diffs and a patched Mailman-2.0.8 tarball are at ftp://www.dairiki.org/pub/mailman/ ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-09-08 13:08 Message: Logged In: YES user_id=45814 More fixes. * Mailman/FilteringMimeWriter.py: Fixes for bugs in python 1.5.2's quopri library module. The plaintext patches are at version 0.14. Look for the patches on Mailman 2.0.6, as well as a complete tarball of patched Mailman 2.0.6 code at ftp://www.dairiki.org/pub/mailman/ Patches on 2.0.6 are also attached to this page. ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-08-25 12:34 Message: Logged In: YES user_id=45814 More fixes: * Mailman/PlaintextMimeWriter.py: Change Message-ID: of filtered messages. * Mailman/pythonlib/multifile.py: Fix obscure but occasionally fatal bug. The first fix is very minor. The second fix fixes a bug which caused the plaintext filter to fail occasionally. Diffs from mailman-2.0.6 are available from this page and are also at: ftp://www.dairiki.org/pub/mailman/mailman-2.0.6-plaintext-0.13.patch.gz Pre-patched mailman-2.0.6 source code is at: ftp://www.dairiki.org/pub/mailman/mailman-2.0.6-plaintext-0.13.tgz ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2001-06-16 11:33 Message: Logged In: NO After applying this patch to 2.0.5, I found that I had to add this line manually to my existing config file $prefix/Mailman/mm_cfg.py... DEFAULT_FORCE_PLAIN_TEXT = 0 If this line is not added, any web requests and any messages posted will produce an error "AttributeError : DEFAULT_FORCE_PLAIN_TEXT". Not sure if I did something wrong or if this is normal, but I wanted to advise others just in case ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-05-19 16:49 Message: Logged In: YES user_id=45814 More fixes: * Mailman/FilteringMimeWriter.py: Handle 'content-type: multipart' (no subtype) gracefully. * Mailman/Handlers/PlainText.py: Catch exceptions (fatal errors) from plaintext filter. When exception is caught, an error is logged, but the message is passed on unfiltered. (A diagnostic message is added to the message headers.) This should make it so little piddly bugs in the filter will get noticed, but at the same time will not cause messages to get stuck in the queue. Patches from mailman-2.0.5 are available from this page and are also at: ftp://www.dairiki.org/pub/mailman/mailman-2.0.5-plaintext-0.10.patch.gz Pre-patched mailman-2.0.5 source code is at: ftp://www.dairiki.org/pub/mailman/mailman-2.0.5-plaintext-0.10.tgz ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-05-17 12:27 Message: Logged In: YES user_id=45814 Another minor bugfix: it turns out pythons mimetools doesn't treat the content-transfer-encoding is a case insensitive fashion --- so now we smash the case ourself. A new patch set on mailman-2.0.5 is available on this page. Pre-patched mailman source code can be found at: ftp://www.dairiki.org/pub/mailman/mailman-2.0.5-plaintext-0.9.tgz ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-05-07 21:38 Message: Logged In: YES user_id=45814 Disregard last. (Apparently one can't attache files bigger than 256 kb.) Mailman-2.0.5 with plaintext patches applied can be found (for a limited time) at: ftp://www.dairiki.org/pub/mailman/mailman-2.0.5-plaintext-0.8.tgz ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-05-07 21:33 Message: Logged In: YES user_id=45814 If you don't want to mess with patching the source, I've also attached (below) a tarball of the mailman-2.0.5 source with my patches already applied. ---------------------------------------------------------------------- Comment By: Geoffrey T. Dairiki (dairiki) Date: 2001-05-07 21:16 Message: Logged In: YES user_id=45814 Here's a rough outline of how to proceed: 1. Start by unpacking a fresh copy of mailman-2.0.5.tgz 2. Change into the top source directory (which was created in the previous step. 3. Try applying my patches with: patch -p1 < [where.ever]/mailman-2.0.5-plaintext-0.8.patch (that's "dash pee one") That should work --- you should not get any warnings or prompts from patch. If you do, something is fishy. 4. Run ./configure and 'make install' as usual (read mailman's INSTALL for instructions on this.) Feel free to write me at <dairiki@dairiki.org>. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2001-05-07 20:30 Message: Logged In: NO For *some* reason when I apply the patch (the newest one) to my freshly downloaded version of Mailman 2.0.5 and compile and install mail never reaches the list. I've tried without the patch and everything works fine... perhaps I'm patching wrong? I'm just saying: patch < name_of_patch It makes me fix a few paths to some of the files, but that's it... :-/ Any help would be appriciated! ---------------------------------------------------------------------- Comment By: Geoffrey T.
