Upgrade to MariaDB 10.2
by Huji Lee 02 Jun '19

02 Jun '19

Hi all, Does anyone know when we will be upgrading the Clouds replica DBs to MariaDB 10.2? I am asking mainly because we are on 10.1.33, 10.3 is now out, and since 10.2 support for CTEs (WITH statements) has been added which is very handy. Thanks, Huji

[Cloud-announce] NFS maintenance next week
by Brooke Storm 29 Aug '18

29 Aug '18

We will be performing some updates (including reboots) on the tools NFS servers for Toolforge and CloudVPS instances that use project NFS (with the exception of dumps) at 1500 UTC on Wed Aug 29. The maintenance window will be two hours and more than one NFS server failover is expected during that time. This could cause some temporary impact to performance and load on the various connected servers during failovers.

[Cloud-announce] VPS users, please claim your projects (second notice)
by Andrew Bogott 26 Aug '18

26 Aug '18

In an attempt to identify abandoned VPS projects, I've created a wiki page that lists all existing projects, here: https://wikitech.wikimedia.org/wiki/Cloud_VPS_2018_Purge Currently 85 projects[2] on that list are unclaimed. If you are a VPS user, please visit that page and mark any projects that you use as {{Used}}. Note that it's not necessary for you to be a project admin to mark something -- if you know that you're currently using a resource and want to keep using it, go ahead and mark it accordingly. If you /are/ a project admin, please take a moment to mark which VMs are or aren't used in your projects. When October arrives, I will shut down and begin the process of reclaiming unused projects. If you think you use a VPS project but aren't sure which, I encourage you to poke around on https://tools.wmflabs.org/openstack-browser/ to see what looks familiar. You can also log in to http://horizon.wikimedia.org which will provide you with a handy menu of projects that you are currently a member of. Thank you! -Andrew and the WMCS team [1] https://phabricator.wikimedia.org/phame/post/view/112/neutron_is_finally_co… [2] Here, for good measure, is that list.

Open beta testing period for PHP 7.2 webservices in Toolforge
by Kunal Mehta 26 Aug '18

26 Aug '18

Hi, I'm happy to announce that PHP 7.2 webservices are available in Toolforge for beta testing. PHP 7.2 brings in 3 years of improvements since 5.6 (released back in 2014), including new features and performance improvements. How to try it out: $ webservice stop; webservice --backend=kubernetes php7.2 start If you need to run something on the command line for setup, like composer, you'll need to enter the shell instance: $ webservice --backend=kubernetes php7.2 shell While most code should just work, not all will. You should read the upstream migration guides[1] for help on porting your code. Some PHP extensions have been removed, notably `mysql` (use `mysqli` or PDO instead). Beta period notes: * I'm not going to be on hand to monitor your tool 24/7 (this is a free time project for me too). * Expect bugs, don't switch tools over that need to be up 100% of the time. * #wikimedia-cloud on freenode is a great place to ask for help! * If you do find bugs, please file subtasks of [2] or comment there (I can file separate tasks if necessary). * Documentation on-wiki is probably out of date. I'll work on that soon. * If everything goes well, I plan to declare 7.2 out of beta and stable in about 2-3 weeks. Technical details: * You can see installed PHP 7.2 extensions/configuration with the phpinfo tool.[3] * PHP 7.2 is running on top of Debian Stretch, which will pull in newer versions of many system libraries. ** Notably lighttpd 1.4.45 (vs 1.4.35 previously). And, thank you to all the people who have already helped with testing and finding issues during the alpha period.

regarding PHP client code for bots
by Yetkin Sakal 25 Aug '18

25 Aug '18

Hello, My client code for YBot (in PHP) working fine locally refuses to log in on Toolforge servers. What I get upon a login request is the following: [login] => Array ( [result] => NeedToken [token] => 6c254247bcaf8d7ad98dbfdabbb96bfa5b819379+\ ) I do get a successful login response locally, though. Is there any chance we are affected by a configuration issue on Toolforge servers? Any ideas?

[Mediawiki-api-announce] Deprecations and changes in API action=compare
by Brad Jorsch (Anomie) 23 Aug '18

23 Aug '18

In preparation for multi-content revisions (MCR), we've made[1] several changes to action=compare. These changes should be deployed to Wikimedia wikis with 1.32.0-wmf.19 or later. The changes should also be available on the Beta Cluster[2] soon for testing. *== Supplying content using templated parameters ==* For MCR, when specifying content (as with the `fromtext` and `totext` parameters) we need the ability to specify content for each "slot" in the page. The way this works for action=compare is that (1) the base revision is determined using the parameters that identify the page and/or revision (`fromtitle`/`totitle`, `fromrev`/`torev`, and so on), then (2) the new `fromslots`/`toslots` parameter specifies which slots are being changed, and then (3) new parameters for each value of `fromslots`/`toslots` specify the content for each of those slots. In the API help, these new parameters for each value of `fromslots`/`toslots` are described as "templated parameters" and have a placeholder in their names. Where the help describes "totext-{slot}", it's meaning that if you supply "toslots=foo|bar" then there would be corresponding parameters "totext-foo" and "totext-bar" to supply the text for those two slots. In Special:ApiSandbox, input fields for "totext-foo" and "totext-bar" will appear when you enter those value for "toslots". In the future templated parameters will be introduced for action=edit and action=parse as well, and other modules as the need arises. *== Deprecations and changes in action=compare ==* The following parameters are deprecated, with replacements as indicated. - `fromtext` is replaced with `fromtext-main` with `fromslots=main`. - `fromcontentmodel` is replaced with `fromcontentmodel-main` with `fromslots=main`. - .`fromcontentformat` is replaced with `fromcontentformat-main` with `fromslots=main`. - `totext` is replaced with `totext-main` with `toslots=main`. - `tocontentmodel` is replaced with `tocontentmodel-main` with `toslots=main`. - .`tocontentformat` is replaced with `tocontentformat-main` with `toslots=main`. The `fromsection` and `tosection` parameters are also deprecated with no direct replacement. The intended use case for these parameters was to simulate a diff of a section edit, by supplying the edited section's text as `totext` and supplying `fromsection` to extract just the section being edited from the current revision. This use case is now supported by specifying `totext-main` as the edited section's text and supplying `tosection-main` to identify the section being edited, which will be combined into the existing content as for a section edit. This will result in a diff more closely matching that returned for a section edit from the web UI with respect to line numbers and context lines. By default action=compare will return one HTML blob combining the diffs of all slots, much as is shown in the web UI. The new `slots` parameter may be used to get separate HTML blobs for each slot's diff and to limit which slots' diffs are returned.. *== Other notes ==* Note that the already-deprecated[3] diffing parameters to revision-related modules, such as the rvdifftotext parameter to action=query&prop=revisions, will not be updated for MCR. Code using these parameters should be updated to use action=compare instead.
