Trac to Gitlab Migration Information
by Alexander Færøy 15 Jun '20

15 Jun '20

# tl;dr Trac is retiring; we're moving to gitlab. We wanted to do this in a more elegant way, but we're low on resources, and there are going to be some bumps in the road here. If you use or engage with the Tor bugtracking system or our wiki, this email may be relevant to you. If you don't, you can stop reading now. # Why migrate? We're hoping gitlab will be a good fit because: * Gitlab will allow us to collect our different engineering tools into a single application: Git repository handling, Wiki, Issue tracking, Code reviews, and project management tooling. * Gitlab is well-maintained. * Gitlab will allow us to build a more modern approach to handling CI for our different projects. This is going to happen after the ticket and wiki migration. (Note that we're only planning to install and use the freely licensed version of gitlab. There is an "enterprise" version with additional features, but we prefer to use free software whenever possible.) # What's the plan? On Friday June 12th, we're going to put trac into read-only mode. You'll be able to read trac, but not make any changes to it. That's when we'll start migrating to gitlab. We have been doing a bunch of trial migrations and we may need to do a few more until we get it right. We anticipate that gitlab will be pretty unstable over the weekend. We hope we'll be in a stable position on Tuesday, and our gitlab installation will be open for people to use it. It will be up on https://gitlab.torproject.org This won't be as smooth a process as we would like: we're going to lose some features -- but, no data. In the coming weeks, we're going to try to put extra time aside to fix whatever issues come up. We are migrating tickets and wiki from Trac into Gitlab issues and wiki. We will continue having https://git.torproject.org/ as canonical git server. People will be able to move repos into gitlab whenever they are ok with it. # What will break, and when will you fix it? Most notably, we're going to have an interruption in the ability to open new accounts and new tickets. We _did not_ want to migrate without a solution here; we'll try to have at least a stop-gap solution in place soon, and something better in the future. For now, we're planning for people that want to get a new account please send a mail to <gitlab-admin(a)torproject.org>. We hope to have something else in place once the migration is succesful. We're not going to migrate long-unused accounts. Some wiki pages that contained automated listings of tickets will stop containing those lists: that's a trac feature that gitlab doesn't have. We'll have to adjust our workflows to work around this. In some cases, we can use gitlab milestone pages or projects that do not need a wiki page as a work around. # What will keep working the same as in Trac? We're not going to throw away any ticket data; it'll all be migrated on the new system. We're going to try to keep most old URLs working on systems such as https://bugs.torproject.org/ All existing tickets will keep their current numbers. # How can I... ... report an issue in Tor software? For now, just use one of the mailing lists, if it can't wait till the bugtracker is open again. tor-dev(a)lists.torproject.org is the best mailing list to use for now. ... report an issue in the bugtracker itself? Please hold off till the migration is finished. At that point you can email <gitlab-admin(a)torproject.org>. ... fix a bug? If you have a patch you want to make sure we know about, and it can't wait till the bugtracker is open again, please use one of the mailing lists: tor-dev(a)lists.torproject.org would be best. ... get an account if I'm already an active contributor? Please send a mail to <gitlab-admin(a)torproject.org>. We hope to have something else in place once the migration is successful. All the best, The Gitlab migration folks -- Alexander Færøy

minutes from the sysadmin meeting
by Antoine Beaupré 10 Jun '20

# Roll call: who's there and emergencies Present: anarcat, hiro, weasel. Small emergency with Gitlab. ## Gitlab We realized that the GitLab backups were not functionning properly because GitLab omnibus runs its own database server, separate from the one ran by TPA. In the long term, we want to fix this, but in the short term, the following should be done: 1. that it works without filling up the disk ;) (probably just a matter of rotating the backups) 2. that it backs up *everything* (including secrets) 3. that it stores the backup files *offsite* (maybe using bacula) 4. that it is documented The following actions were undertaken: * make new (rotating disk) volume to store backups, mount it some place (weasel; done) * tell bacula to ignore the rest of gitlab /var/opt/.nobackup in puppet (hiro; done) * make the (rotating) cronjob in puppet, including the secrets in ./gitlab-rails/etc (hiro, anarcat; done) * document ALL THE THINGS (anarcat) - specifically in a new page somewhere under [tsa/howto/backup][], along with more generic gitlab documentation ([34425][]) [tsa/howto/backup]: https://help.torproject.org/tsa/howto/backup/ [34425]: https://trac.torproject.org/projects/tor/ticket/34425 # Roadmap review We proceeded with a review of the [May and June roadmap][]. [May and June roadmap]: https://trac.torproject.org/projects/tor/wiki/org/teams/SysadminTeam#May We note that this roadmap system will go away after the gitlab migration, after which point we will experiment with various gitlab tools (most notably the "Boards" feature) to organize work. alex will ask hiro or weasel to put trac offline, we keep filing tickets in Trac until then. weasel has taken on the kvm/ganeti migration: * [moly](https://bugs.torproject.org/29974) * [majus](https://bugs.torproject.org/31784) * [kvm5](https://bugs.torproject.org/33084) hiro will try creating the next ganeti node to get experience on that [34304][]. [34304]: https://trac.torproject.org/projects/tor/ticket/34304 anarcat should work on documentation, examples: * how to add a disk on a ganeti node (done) * [LDAP / ud-ldap][] * [gitlab][] [LDAP / ud-ldap]: https://trac.torproject.org/projects/tor/ticket/34426 [gitlab]: https://trac.torproject.org/projects/tor/ticket/34425 # Availability planning We are thinking of setting up an alternating schedule where hiro would be available Monday to Wednesday and anarcat from Wednesday to Friday, but we're unsure this will be possible. We might just do it on a week by week basis instead. We also note that anarcat will become fully unavailable for two months starting anywhere between now and mid-july, which deeply affects the roadmap above. Mainly, anarcat will focus on documentation and avoid large projects. # Other discussions We discussed TPA-RFC-2, "support policy" ([tsa/policy/tpa-rfc-2-support][]), during the meeting, because someone asked if they could contact us over signal (the answer is "no"). [tsa/policy/tpa-rfc-2-support]: https://help.torproject.org/tsa/policy/tpa-rfc-2-support/ The policy seemed to be consistent with what people in the meeting expected and it will be sent for approval to tor-internal shortly. # Next meeting TBD. First wednesday in July is a bank holiday in Canada so it's not a good match. # Metrics of the month * hosts in Puppet: 74, LDAP: 77, Prometheus exporters: 128 * number of apache servers monitored: 29, hits per second: 163 * number of nginx servers: 2, hits per second: 2, hit ratio: 0.88 * number of self-hosted nameservers: 6, mail servers: 12 * pending upgrades: 35, reboots: 48 * average load: 0.55, memory available: 346.14 GiB/952.95 GiB, running processes: 428 * bytes sent: 207.17 MB/s, received: 111.78 MB/s * planned buster upgrades completion date: 2020-08-18 Upgrade prediction graph still lives at https://help.torproject.org/tsa/howto/upgrades/ Now also available as the main Grafana dashboard. Head to <https://grafana.torproject.org/>, change the time period to 30 days, and wait a while for results to render. -- Antoine Beaupré torproject.org system administration

Planet Testing
by Alexander Færøy 05 Jun '20

05 Jun '20

Hello Core Tor Members, (This email was also sent to tor-internal@ some days ago, but it is not secret, so we can share it here as well. Feel free to ignore if you have already read it) Antonela made progress on a theme for a "Planet Tor" blog aggregator over the weekend. We still need to tune a few things, but we can do that over the next weeks or so. We are looking for some core Tor members who occasionally write about Tor stuff on their blogs. Right now, all articles should be in English, but we can later add an aggregator for posts in other languages, too, if there is an interest in that. Please reply directly to me (not a list reply) with the following information if you are interested: 1. Your name formatted in the way you want it listed. 2. Your nickname (if any) formatted in the way you want it listed. 3. A link to your blog's "front page." 4. A link to your blog's RSS and/or Atom feed. If you have a Tor specific "category" or "tag" and your blog engine supports it, you can give us a direct link to that feed such that "only" things you tag explicitly with Tor will show up here. Up to you. 5. (optionally) A link to your Twitter handle. 6. (optionally) A link to your Mastodon handle. Thanks! Antonela and I will continue to experiment a bit with this over the next period of time. The repository for the work can be found at https://gitlab.torproject.org/ahf/planet and is tracked in https://bugs.torproject.org/9721 Have a nice weekend! All the best, Alex. -- Alexander Færøy

Hi! Metrics Meetings are happening every Thursday at 15UTC in #tor-meeting in irc.oftc.net Here are the minutes for the meeting of June 4rd: http://meetbot.debian.net/tor-meeting/2020/tor-meeting.2020-06-04-15.00.log… Meeting pad: https://pad.riseup.net/p/tor-metricsteam-2020.1-keep And here is the pad notes: ----------------------------------------------------- Agenda Thursday, June 4th, 15 UTC ----------------------------------------------------- OnionPerf project: https://trac.torproject.org/projects/tor/wiki/org/sponsors/Sponsor59 Roadmap for June: Roadmap draft: https://people.torproject.org/~karsten/volatile/scalability-and-performance… What tasks are we missing in this roadmap draft? There are some tickets in Metrics/Cloud #33309->33313;#32725 Write some simple scripts to generate ID hexes of relays with certain properties as input for #33260. What should we include in the roadmap for the 4 weeks in June from 2020-06-05 to 2020-07-02 with 2.5 points per week or 10.0 points total capacity? Tickets that are almost done and that we can likely resolve quickly Add CDF-DL graph (#33257), 0.2 points remaining +1+1+1 Fix message logging and filtering (#29369), 0.2 points remaining +1+1+1 Make -o/-i arguments mutually exclusive (#34316), 0.1 points remaining +1+1+1 Find out why onion service measurements have gotten slower (#34303), 0.1 points remaining +1+1+1 Analyze unusual distribution of time to extend to first hop in circuit (#34257), 0.4 points remaining +1+1+1 Add digests and sizes to index.xml (#29365), 0.2 points remaining +1+1+1 Add single onion service mode (#29368), 0.2 points remaining +1+1+1 Enhancements related to TGen and Shadow Update OnionPerf to TGen 1.0.0 (#33974), 2.0 points remaining+1+1+1 Circuit build timeouts Add CBT events to Onionperf result files (#33420), 0.7 points remaining +1 Include more events about CBT in results (#33422), 0.5 points remaining +1 Long-running measurement instances Update metrics-web to only plot "official" data (#33397), 0.5 points remaining+1 Check OnionPerf instances from Nagios (#28271), 1.0 points remaining+1 Guards Measure static guard nodes with OnionPerf (#33399), 1.9 points remaining +1+1 Track which Guard is used for experimental measurements (#33421), 3.0 points remaining +1+1 Measurement mode Measure mode with arbitrary tgen traffic models (#29370), 0.9 points remaining +1+1 Multiple downloads for oneshot mode (#33432), 0.2 points remaining +1+1 What we're leaving for the next roadmap in July: Enhancements related to TGen and Shadow OnionPerf TGen parser needs reworking (#30362), 3.0 points remaining Replace TorCtlParser with OnionTrace's control log parser (#34213), 2.0 points remaining Long-running measurement instances Add new metadata fields and definitions (#33391), 1.0 points remaining Add new metadata fields to json output (#33392), 0.5 points remaining Guards Add analysis to support static guard measurements (#33419), 2.0 points remaining Measurement mode Develop and deploy tgen model resembling ping (#30798), 5.0 points remaining TGen/Tor integration Document and maybe improve how we're mapping TGen transfers to Tor streams/circuits (#34231), 1.0 points remaining Visualization mode Store measurements in a local database to reduce plotting time (#33259), 5.0 points remaining Split PROXY errors into whatever reasons are given in TorCtl logs (#34218), 0.3 points remaining Add option to filter graphed OnionPerf results by relay fingerprint (#33260), 3.0 points remaining New suggestions from above: There are some tickets in Metrics/Cloud #33309->33313;#32725 Write some simple scripts to generate ID hexes of relays with certain properties as input for #33260.
