[Bug 1096812] [NEW] Threading issues in mailman 3.0.0b2
by David Bell 23 May '15

23 May '15

Public bug reported: I am seeing concurrency issues when using mailman 3 in a threaded application server. Reading the Storm documentation it states that "Store objects are not threadsafe. [...] Therefore, the best policy is usually to create a Store object for each thread which needs one" (https://storm.canonical.com/Manual#Working_with_multiple_threads) In mailman/database/base.py:141 I see a Store being created and cached. As recommended in the storm docs, Stores should not be cached. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1096812 Title: Threading issues in mailman 3.0.0b2 To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1096812/+subscriptions

[Bug 1096066] [NEW] mailman raises exception if passed message not contains text/plain message part
by Robert Niederreiter 23 May '15

Public bug reported: If message sent to mailman not contains a text/plain message part (i.e. only text/html), an error is raised and the message gets swallowed.

[Bug 1023681] [NEW] bin/mailman -C config start does not work with a relativ config path
by AlexanderS 23 May '15

23 May '15

Public bug reported: During testing I encountered, that bin/mailman is not working correctly if you supply a relative path as -C argument. For the main process the path is converted into a absolute path during startup but the bin/master process is getting the relative filename but maybe a different working directory. The attached patch fixes that behavior by supplying the generated absolute pathname to the new process. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1023681 Title: bin/mailman -C config start does not work with a relativ config path To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1023681/+subscriptions

[Bug 987031] [NEW] archival hashes can be shortened
by Jeff Breidenbach 23 May '15

23 May '15

Public bug reported: The draft for archival hashes for mailman specifies 32 character, base 32 encoding. We can get away with 13 characters which expects the first collision at around 50 billion messages. The the wikipedia charts in their "birthday attack" article. It's not like an occasional collision is a big deal and this is not a security issue. ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 ** Tags added: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/987031 Title: archival hashes can be shortened To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/987031/+subscriptions

[Bug 856004] [NEW] "OperationalError: database is locked" encountered under very light load while using REST API
by Stephen A. Goss 23 May '15

23 May '15

Public bug reported: I've seen this error twice while running integration tests (of our own application) that access Mailman 3 using the API. The load on Mailman is very light, as all requests made to the API are serial, never in parallel. Of course the various processing queues in MM3 are separate processes and could be doing work concurrently. The platform is Centos 6.

[Bug 1082495] [NEW] Support bracketed prefixes in subject as filters
by Gordon P. Hemsley 23 May '15

23 May '15

Public bug reported: Many large mailing lists use bracketed prefixes in subjects as a way to filter messages into smaller buckets, allowing some subscribers to read all mail sent to the list while allowing others to filter messages (in their mail client) to read only the messages they are interested in. For example, the W3C's www-style mailing list uses these tags to filter messages based on which CSS spec they refer to. Thus, a subject line that begins "[css3-fonts]" will be assumed to be about only the css3-fonts spec, with a target audience of only those interested in that particular spec and not, say, the css3-flexbox spec (whose subject lines would be prefixed with "[css3-flexbox]"). To handle this, the Mailman archive interface would provide an option to filter only on particular prefixes (as well as messages that don't have any prefixes), allowing a user of the archive to use it as they otherwise would, but filtering the output such that they only see the messages they want to see, instead of the whole archive. In addition, it would be helpful to allow mailing lists to automatically prefix subject lines when the message is sent to an e-mail address using a plus alias. For example, sending mail to www-style+css3-fonts(a)w3.org would prefix the subject line of the message with "[css3-fonts]" in the message sent to subscribers and in the archive, whereas sending mail to www- style+css3-flexbox(a)w3.org would prefix the message with "[css3-flexbox]". It should also be allowed to have multiple prefixes on a message, and having such messages be treated as if they had any prefix individually. In terms of plus aliasing, there are two ways to handle it: (1) allow aliases to specify multiple prefixes in a plus alias using some separator (e.g. a comma: www-style+css3-fonts,css3-flexbox(a)w3.org); or (2) detecting and intercepting when a single message was sent to multiple e-mail addresses with different plus aliases for a single mailing list (e.g. sending the same e-mail to both www- style+css3-fonts(a)w3.org and www-style+css3-flexbox(a)w3.org), treating it as a single message with multiple subject prefixes when sent to subscribers or stored in the archive. Now, I understand that this is likely a huge undertaking, but I think it would go a long way to helping users with large and diverse mailing lists. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1082495 Title: Support bracketed prefixes in subject as filters To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1082495/+subscriptions

[Bug 1070064] [NEW] Add a 'policy' command
by Barry Warsaw 23 May '15

23 May '15

Public bug reported: It would be kind of nice for MM3 to implement a 'policy' command. If you issue this email command, you would receive a response containing an admin supplied policy text. This response should adhere to the general grace period timeouts, and the text should be retrieved via the generalized url retrieval and caching machinery. This way, the same policy text could be retrievable via email command or web ui. There should be a way to request policy documents in multiple languages. ** Affects: mailman Importance: Wishlist Status: New ** Tags: mailman3 ** Changed in: mailman Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1070064 Title: Add a 'policy' command To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1070064/+subscriptions

[Bug 956384] [NEW] Continuous integration and real-world testing
by Andrea Crotti 23 May '15

23 May '15

Public bug reported: This is not a real bug, I would just like to start a discussion about what can be done to set up a continuos integration system. Is there any Jenkins server which can be used? Another thing which I was thinking is if we have some real tests on real systems with various MTA such as Postfix/Exim. I haven't tried it yet but it seems that http://vagrantup.com/ and puppet could really be very nice tools for the job. And we could then 1. fire up a VM 2. install the different MTAs 3. create some complicated mailing lists and check that everything works correctly Other ideas? ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/956384 Title: Continuous integration and real-world testing To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/956384/+subscriptions
