Database running VERY hot
by Darren Smith 12 Mar '18

12 Mar '18

Hello all, We had an old installation of Mailman 2.1 across three servers with over 32,000 mailing lists on them. Due to circumstances beyond my control, we had to shut them down and quickly set up Mailman 3 on a new server. We have Mailman3 set up on a single server this time, as we were having problems with a 3-server setup and Hyperkitty and archives. Long story short, it is up and running, and our users are starting to come back. However, we do not have very many users hitting Postorius and Hyperkitty yet, and we are seeing a distressing number of 504 gateway timeouts. We noticed that there is a significant number of queries to the API whenever hitting Postorius's front page to load the mailing lists, and then on every load. It looks as if it makes a single call to the API to get information about a single list, and does this 10 times - once for each list - to render the page. This gets much worse when users set the view to 200 per page, as they are inclined to do with 32,000 mailing lists... What we've done, actually, is to override the front page and point the users to a different set of static pages where we have all of our lists categorized and searchable, and when they find the list they are looking for, we have a link back to postorius. It has taken a lot of the stress off of the server. However, I still see where the database at times can run VERY hot. We have set up this server to run with PostgreSQL. When I do a ps aux | grep postgres, I find a lot of processes that have been spawned to take care of mailman - a dozen or so. However, one of the threads is taking up about 85% of the load, another thread about 14%, and little dribbles here and there from the rest of the threads. Here are the questions: 1) Has anyone run into problems like these? I would think that maybe this is an issue having so many mailing lists, but honestly there aren't that many people using the system yet. It is going to ramp up as the users realize that we are live again, but we aren't getting that much traffic. 2) Is there any configuration that I can set, especially with regards to the database, so that it can be used more efficiently and not throttle through one or two threads? Please let me know what further information I can provide. Thanks in advance for any help or advice! Silas

Deactivate list without deleting it?
by Colin Watson 03 Mar '18

03 Mar '18

Hi, I'm experimenting with a port of Launchpad's mailing list infrastructure to Mailman 3. If Barry's reading, he may remember that this is no trivial task, so I'm very definitely not promising that it will be done any time soon. :-) However, for the most part it looks relatively tractable with the aid of the plugin improvements in Mailman 3.2.0; I have the rough outline of a plugin that implements much the same feature set as our current pile of monkey-patches against Mailman 2.1 in a much nicer way. One of the major things I haven't figured out yet is list deactivation and reactivation. In our current 2.1-based code, you can deactivate a list in a reversible way, which basically tars up the list directory so that the list archives can be restored later. This isn't a native operation in 2.1, but it could be done because everything lived on the filesystem. In 3, it's less trivial. We could go to some effort to dump things out of the HyperKitty database and restore it on reactivation, but that seems rather complex and a bit silly. Ideally, I'd like mailing lists to have a "deactivated" state in addition to full deletion. In this state, the list would appear nonexistent for most purposes: incoming email would be rejected, Postorius would deny its existence, etc. There'd need to be corresponding extensions to the IArchiver interface which caused the archiver to put its archives of that list into a corresponding deactivated state, in which it would retain the messages but queries for them would return 404 or similar; these extensions would need to be optional, since while it should be relatively easy to do this in HyperKitty it could be hard or impossible for other archivers, and perhaps this should be a separate operation from deactivating the list itself since people may want to close a list while leaving its archives accessible. Has there been any discussion of this in the past, or any advice as to implementation strategy? Thanks, -- Colin Watson [cjwatson(a)ubuntu.com]

import21: A string literal cannot contain NUL (0x00) characters.

Docker-mailman 0.1.1. I am facing errors when using import21 to import list archives. The error message is "A string literal cannot contain NUL (0x00) characters." and the import stops, thus importing only mails up to 2009. The dublicates is mails already imported when retrying.

Hi, When starting mailman in a terminal, then it works: --8<---------------cut here---------------start------------->8--- $ mailman start Starting Mailman's master runner $ --8<---------------cut here---------------end--------------->8--- But from "cron", it seems to hang.

How could I solve this issue please? TIA for any hints, -- Peter

Hi, I would like to point "https://my-domain.org/" to the list of mailing-lists of this domain. How should I setup my Apache configuration and/or the urlpatterns please? With my actual configuration, the above URL is always rewritten to https://my-domain.org/postorius/lists/ These are my urlpatterns: urlpatterns = [ url(r'^$', RedirectView.as_view( url=reverse_lazy('list_index'), permanent=True)), url(r'^postorius/', include('postorius.urls')), url(r'^archive/', include('hyperkitty.urls')), url(r'', include('django_mailman3.urls')), url(r'^accounts/', include('allauth.urls')), url(r'^admin/', include(admin.site.urls)), ] TIA for any help, -- Peter
