Mailman with Python 3.12
by Andrew Hodgson April 26, 2024

April 26, 2024

Hi. What's the latest on Mailman with Python 3.12? Looking at Ubuntu 24.04 upgrade plans and realised it comes with Python 3.12. Ubuntu are shipping Mailman packages from Debian so not sure if they have made any changes to make Python 3.12 work. I don't use those packages myself. Andrew.

Slow performance when listing members on Postorius
by Alan So April 24, 2024

April 24, 2024

We are about to upgrade to Mailman core 3.3.9 and Postorius 1.3.10. We notice that for setup with large number of members, the performance is much slower when listing members on web (Postorius). Further troubleshooting show that there are quite a number of API calls which do not appear in Mailman core 3.3.5 and Postorius 1.3.6 when we list members. [17/Apr/2024:14:12:22 +0800] "GET /3.1/members/33a6266d0a04472c8d5d6c78869a964c/preferences HTTP/1.1" 200 156 "-" "GNU Mailman REST client v3.3.5" [17/Apr/2024:14:12:22 +0800] "GET /3.1/members/7a18b7cb90a34ac98881a3f01b5488d1/preferences HTTP/1.1" 200 156 "-" "GNU Mailman REST client v3.3.5" [17/Apr/2024:14:12:22 +0800] "GET /3.1/members/61c6c3e2aaf443babd3bd191519b0424/preferences HTTP/1.1" 200 156 "-" "GNU Mailman REST client v3.3.5" [17/Apr/2024:14:12:22 +0800] "GET /3.1/members/8dd681165b8c436fac6793cae1ed2c27/preferences HTTP/1.1" 200 156 "-" "GNU Mailman REST client v3.3.5" Further tests showing that each database query using "_member_id" in table member can take as much as 0.3 to 0.5 seconds for some large installations. The default 25 members per page mean that it will take at least 7.5 to 12.5 seconds. Changing to 200 members per page will take even longer time. We wonder whether "_member_id" should be indexed just like most other id in the database mailman_core in order to solve the issue. Or are there any other workarounds? +----------------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | _member_id | char(32) | YES | | NULL | | | role | int(11) | YES | MUL | NULL | | | list_id | varchar(255) | YES | MUL | NULL | | | moderation_action | int(11) | YES | | NULL | | | address_id | int(11) | YES | MUL | NULL | | | preferences_id | int(11) | YES | MUL | NULL | | | user_id | int(11) | YES | MUL | NULL | | | bounce_score | int(11) | YES | | NULL | | | last_bounce_received | datetime | YES | | NULL | | | last_warning_sent | datetime | YES | | NULL | | | total_warnings_sent | int(11) | YES | | NULL | | +----------------------+--------------+------+-----+---------+----------------+

Change config to create a new list with all archives off
by Tibor Molnar April 21, 2024

April 21, 2024

Can archiving be changed anywhere in mailman3 configs, so then all new lists created do not archive by default?

Mailman 3 hosting query
by Bill Robertson April 18, 2024

April 18, 2024

Hi I'm investigating the possibility of transferring a fairly small mailing list I own from Google Groups to MM3 via a hosting service. I'd appreciate any pointers regarding what I should be looking out for with companies that offer this service It also seems very hard to find out which hosting companies are worth considering (In particular, reliability and support are important) Any help much is much appreciated Thanks

Mailman-web stop responding.
by Paul Rubin April 17, 2024

April 17, 2024

I was trying to administrate a list and discovered that mailman-web was unresponsive. I have tried stopping and restarting it. The error logs update for the startup, but not when anything connects to localhost:8000. The last entry in uwsgi.log was two hours ago and nothing has been added since. I tried both lynx http://localhost:8000 and telnet to http://localhost 8000 and GET request instantly closes the port and logs nothing. As far as I can tell both mailman and postgres are working fine. This is what logs on startup. ==> uwsgi-error.log <== *** Starting uWSGI 2.0.22 (64bit) on [Sun Apr 14 10:45:51 2024] *** compiled with version: 13.2.1 20230912 [revision b96e66fd4ef3e36983969fb8cdd1956f551a074b] on 05 October 2023 13:37:28 os: Linux-6.5.4-1-default #1 SMP PREEMPT_DYNAMIC Wed Sep 20 05:07:04 UTC 2023 (fdd7e9e) nodename: mail.rubinsoftware.com machine: x86_64 clock source: unix detected number of CPU cores: 4 current working directory: / detected binary path: /opt/mailman/venv/bin/uwsgi !!! no internal routing support, rebuild with pcre support !!! your processes number limit is 15246 your memory page size is 4096 bytes detected max file descriptor number: 1024 lock engine: pthread robust mutexes thunder lock: disabled (you can enable it with --thunder-lock) uwsgi socket 0 bound to TCP address 0.0.0.0:8000 fd 8 Python version: 3.11.5 (main, Aug 31 2023, 07:57:41) [GCC] PEP 405 virtualenv detected: /opt/mailman/venv/ Set PythonHome to /opt/mailman/venv/ Python main interpreter initialized at 0x7f2c3d709d58 python threads support enabled your server socket listen backlog is limited to 100 connections your mercy for graceful operations on workers is 60 seconds mapped 250128 bytes (244 KB) for 4 cores *** Operational MODE: preforking+threaded *** added /etc/mailman3/ to pythonpath.

mailman3 digest sending questions and also adding docker to the mix
by bob B April 17, 2024

April 17, 2024

So I have been down the digest rabbit hole. So to confirm my assumptions/findings: Digest size threshold---- means when the total size of held messages hits this setting, a digest is sent Digest Volume Frequency. ---- specifies when the digest volume number gets incremented for digest messages, IT DOES NOT send out digests based on the setting, daily, weekly ... So what does the GUI setting "Send Digest Periodically yes no" do? how periodically does it send digests, if this is set to yes? If I want to send a digest out for a list every day, or every week, how do I set that, especially in the docker environment? Is this something that can be configured in the GUI and configured by each of my list admins? I found that ”'mailman digests --periodic' via cron” should be set in googling, but does that mean I have to do a cron job for any list that wants a scheduled digest sent? My use case is, that I have a list admin who set a size threshold, but regardless of that, they also want their list digest sent out daily, they thought it was the "Digest Volume Frequency" setting but that is not correct. However in their testing they are not getting daily digest, they are getting digests only when the threshold is reached, BUT they have "Send Digest Periodically" set to "yes" and "Enable Digests" is set to "yes"
