As part of routine security maintenance, we'll be rebooting all VMs and
virtualization hosts next Wednesday starting at 14:00 UTC (7AM San
Francisco time).
Toolforge users should be largely unaffected by this activity. Other
projects (including deployment-prep) will experience sporadic downtime,
a few minutes for each interruption.
The entire process will take several hours. If you need a to-the-minute
advance schedule for any particular reboot, please let me know and I'll
put your system at the start.

ToolsDB will be undergoing maintenance and updates, Tuesday, June 5th at 1500 UTC to 1600 UTC.
Actual outage times should be fairly brief, but during this time the database will be taken offline and the system rebooted. Due to the expected brief nature of the outage and the fact that some tables are not replicated (see https://wikitech.wikimedia.org/wiki/Help:Toolforge/Database#ToolsDB_Backups… <https://wikitech.wikimedia.org/wiki/Help:Toolforge/Database#ToolsDB_Backups…>), we are not planning on failing over to the replica at this time.

Dumps consumers:
Forwarding this note from the xmldatadumps-l(a)lists.wikimedia.org list
about an upcoming change to the number of files generated for some
wikis (for example dewiki's stub-articles dumps).
If you use dumps regularly in your tool, please do subscribe to the
xmldatadumps-l(a)lists.wikimedia.org list [0] for future notices like
this. The list is generally low volume and high signal with
announcements of process change as well as operational issues that may
slow dumps generation.

Subject: [Xmldatadumps-l] change to output file numbering of big wikis
To: Wikipedia Xmldatadumps-l <Xmldatadumps-l(a)lists.wikimedia.org>,
Wikimedia developers <wikitech-l(a)lists.wikimedia.org>
TL;DR:
Scripts that reply on xml files numbered 1 through 4 should be updated
to check for 1 through 6.
Explanation:
A number of wikis have stubs and page content files generated 4 parts
at a time, with the appropriate number added to the filename. I'm
going to be increasing that thi month to 6.
The reason for the increase is that near the end of the run there are
usually just a few big wikis taking their time at completing. If they
run with 6 processes at once, they'll finish up a bit sooner.
If you have scripts that rely on the number 4, just increase it to 6
and you're done.
This will go into effect for the June 1 run and all runs afterwards.
Thanks!

We upgraded the Mono/.NET framework in Toolforge/GridEngine from the 3.x
version to 5.x [0].
We discovered that some tweaking is required due to some weird behavior
regarding memory allocation by the framework [1].
The first symptom you will see is your boot doing high CPU load (spins).
The fix is easy, just telling Mono that more memory is available when
running the tool/bot. But you require to cancel your job submissions and
resend. Please refer to the phabricator bug [1] for more details.
Sorry for the inconvenience.

Some subscribers to this list who also use MediaWiki APIs in their
tools may not know about the
mediawiki-api-announce(a)lists.wikimedia.org and
mediawiki-api(a)lists.wikimedia.org lists, so I am reposting this
announcement here. Please respond with any questions/concerns about
the API change on the mediawiki-api(a)lists.wikimedia.org rather than
this list.

Subject: [Mediawiki-api-announce] BREAKING CHANGE: Passing too many
values for a multi-valued parameter waring is becoming an error
To: mediawiki-api-announce(a)lists.wikimedia.org
The API has traditionally ignored values beyond the allowed limit,
returning a warning for this situation since 2008(!). It's long past
time for this error situation to actually raise an error, as requested
in https://phabricator.wikimedia.org/T41936.
This is happening in https://gerrit.wikimedia.org/r/433742. It should
be deployed to Wikimedia wikis with 1.32.0-wmf.6 or later, see
https://www.mediawiki.org/wiki/MediaWiki_1.32/Roadmap for the
schedule.
Logs indicate that few clients on Wikimedia wikis are hitting the
warning. You can check your client by seeing if you're receiving a
"Too many values supplied for parameter" warning, or by using
Special:ApiFeatureUsage for your client's user agent and looking for a
"too-many-X" code.
If your client is affected, the solution is to divide the values into
batches of the appropriate size. Generally the limit is 50 values for
clients without the apihighlimits right and 500 for clients with that
right. The limits for any particular parameter are documented in the
auto-generated help and are available in machine-readable format via
action=paraminfo.

Hi,
since the beginning of this month we found the need to upgrade the
version of mono framework in Toolforge to something newer [0].
Affected tools/boots maintainers were aware of the upcoming changes, but
in case some of you are developing a new tool/boot, please just note the
change:
mono-complete was upgraded:
* from 3.2.8+dfsg-4ubuntu1.1
* to 5.12.0.226-0xamarin3+ubuntu1404b1
Users that were using their own mono framework versions (because ours
was old) could try now using our new.
Please, if you detect any regression, let me know, we can rollback this
if required.

Hello!
The Cloud Services team is traveling quite a bit in the next few weeks:
the Hackathon, the OpenStack Summit, and some personal travel. There
will always be at least one person available for emergencies, but please
be patient if we're slow to respond to requests.
Everyone should be back by the first of the month.
- Andrew + the Cloud Services team

As part of some long-deferred routine maintenance, we need to update
(and, in one case, physically move) the network servers that handle all
traffic between WMCS instances. During each change, all WMCS network
traffic (including network access to all tools and VMs) will be
interrupted for several minutes.
The first outage will be:
Tuesday, May 15 at 13:00 UTC
The second outage will be three hours later:
Tuesday, May 15 16:00 UTC
In each case outages should last no more than ten to fifteen minutes.
More details about this move can be found at
https://phabricator.wikimedia.org/T193579 .
-Andrew
