    • erp5: ERP5 and Jupyter integrated together · 519a575d
      This patch series teaches ERP5 software release to automatically instantiate
      Jupyter notebook web UI and tune it to connect to ERP5 by default. When Jupyter
      is enabled, it also installs on-server erp5_data_notebook bt5 (see
      erp5!29 and erp5@f662b5a2) which handles code execution requested
      for Jupyter.
      
      For ERP5 - for security and backward compatibility reasons - Jupyter
      instantiation and erp5_data_notebook bt5 install happen only if jupyter is
      explicitly enabled in instance parameters. The default is not to have Jupyter
      out of the box.
      
      On the other hand for Wendelin SR, which inherits from ERP5 SR, the
      default is to have Jupyter out of the box, because Wendelin SR is fresh
      enough without lots of backward compatibility needs, and Jupyter is
      usually very handy for people who use Wendelin.
      
      --------
      
      NOTE Currently erp5-data-notebook bt5 has the following limitations (see
      details on !43 and erp5!29):
      
      - errors are not reported properly to users;
      - state is not fully saved to ZODB.
      
      the latter point means notebook works only if it is connected to Zope family
      with only 1 zope process. Hopefully this will be resolved some day.
      
      Technical overview about how the integration is done itself on slapos part and
      other notes are in 0a446263.

    • Jupyter: ERP5 kernel sends code using POST · cf117ccd
      Query strings used on GET requests have size limitations
      on servers and this causes big code cells to not be executed
      at all, returning only an Internal Server Error with no
      further explanation.

    • erp5: Provide pandas, scikit-learn & matplotlib out of the box · 5cd3fc51
      Pandas and scikit-learn are handy to have for data processing which we
      are going to do more and more in ERP5 context. Matplotlib is very handy
      to have when one works with Jupyter, but also can be used by just
      backend code to generate graphs.
      
      From this point of view it makes sense to have this eggs always
      available out of the box. To do so move them from Wendelin to ERP5.

      ~~~~
      
      For integration, we reuse already established in ERP5 infrastructure, to
      request various slave instances, and request Jupyter in a way so it
      automatically tunes and connects to balancer of one of Zope family.
      
      Jupyter code itself is compiled by reusing
      software/ipython_notebook/software.cfg, and Jupyter instance code is
      reused by hooking software/ipython_notebook/instance.cfg.in into ERP5 SR
      properly (the idea to override instance-jupyter not to render into
      default template.cfg is taken from previous work by @tiwariayush).
      
      ~~~~
      
      I tested this patch inside webrunner with create-erp5-site software type and
      various configurations (whether to have or not have jupyter, to which zope
      family to connect it, etc).
      
      I have not tested frontend instantiation fully - because tests were done only
      in webrunner, but I've tried to make sure generated buildout code is valid for
      cases with frontend.
      
      NOTE the code in this patch depends erp5_data_notebook bt5 (erp5!29) which just got merged to erp5.git recently (see erp5@f662b5a2)
      
      NOTE even when erp5_data_notebook bt5 is installed, on a freshly installed ERP5, it
      is required to "check site consistency" first, so that initial bt5(s) are
      actually installed and erp5 is ready to function.

    • GitLab Software Release - first version · 866d9051
      Hello up there,
      
      Here comes SlapOS port of GitLab. We start from GitLab 8.2.X as that is what we
      currently run on KVM on lab.nexedi.com, so that our data can be
      straightforwardly migrated.
      
      The SR compiles all needed software and organized all (sub-)services in one
      partition and interconnects them with unix sockets for security and speed
      reasons (see patch "gitlab: Make a plan to base instance layout on
      gitlab-omnibus and to interconnect all internal services").
      
      Services configuration files are originally taken from omnibus-gitlab
      "distribution" and incrementally ported to slapos variant. This way we
      establish a (imho) good path on how to track upstream changes and minimize our
      delta & effort supporting it.
      
      GitLab itself is patched (above patches that were already applied by upstream):
      
        - to support HTTP(S) only
        - to show site's ICP number
        - to speedup raw blob downloading ~ 17x times
          ( see patch "gitlab: Optimize raw blob downloading" for details and
            https://gitlab.com/gitlab-org/gitlab-workhorse/merge_requests/17 )
      
      Overall it should work and we should finally be able to migrate slapos.git
      (because of raw blob downloading is not slow now) to GitLab and all other
      Nexedi git repositories.
      
      Thanks,
      Kirill
      
      P.S.
      
      Somewhat outdated, but this picture on GitLab architecture might help to
      understand how parts are glued together:
      
      https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/development/architecture.md
      
      P.P.S.
      
      Native resiliency is not implemented yet, but we should be able to use gitlab
      inside resilient webrunner already.

    • gitlab: First SR version works - freeze md5 sums · 729be3b8
      We've reached a state where first gitlab SR version should work. So as
      promised let's freeze the md5 checksums.
      
      All later patches should update corresponding md5 info when they change
      a file.

    • gitlab: Optimize raw blob downloading · a913c2e4
      In slapos we do a lot of automated software rebuild constantly, and thus
      there is constant flow of requests to get raw blobs from git service,
      e.g. like this
      
          https://lab.nexedi.com/nexedi/slapos/raw/master/software/wendelin/software.cfg
      
      A lot of requests comes to slapos.git repository and currently gitlab,
      out of the box, cannot keep up with that load.
      
      I've prepared patches to offload raw blobs download requests handling
      from unicorn (ruby) to gitlab-workhorse (go), and that resulted in ~ 17x
      speedup - e.g. previously our std shuttle can handle ~ 70 raw-blob
      requests/s and with my changes it is now ~ 1200 requests/s.
      
      The patches were sent upstream
      
          https://gitlab.com/gitlab-org/gitlab-workhorse/merge_requests/17
      
      and we discussed with GitLab people and made a plan how to proceed
      incrementally. It will probably take some time for gitlab team to fully
      accept the approach though.
      
      For now we can use our gitlab-workhorse fork. The patches itself are:
      
          kirr/gitlab-workhorse@1b274d0d

    • gitlab: Switch to "GitLab Nexedi Edition" · 74d4ea62
      GitLab Nexedi Edition is currently upstream 8.2.X + the following
      patches:
      
          - HTTP(S) is made to be default clone protocol
      
              kirr/gitlab-ce@5c1f2fb3
      
            and SSH info is completely removed from UI
      
              kirr/gitlab-ce@dfe9fb16
              kirr/gitlab-ce@f3f84743
      
            so essentially the only way to access a repository is via HTTP(S).
      
          - Rake check tasks are adjusted to exit with non-zero code if there
            is a failure
      
              kirr/gitlab-ce@a93ae418
      
            We need this for promises to work correctly with failures being
            detected, not silently skipped. The patch was sent upstream:
      
              https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/1885
      
          - GitLab supports setting up site's ICP License in gitlab.yml and
            shows it in appropriate places together with info about GitLab
            itself:
      
              kirr/gitlab-ce@e7e0fd88
              kirr/gitlab-ce@79c127e6
      
          + other cosmetic/minor changes.
      
      More patches will probably come (e.g. apply a single patch from a
      merge-request with `git am` without creating merge commit for just 1
      patch, etc) but for now that's all.
      
      NOTE ICP is non-ascii text with hieroglyphs. slapos.core was taught to
          be able to pass parameters with non-ascii values to instance:
      
              slapos.core@347d33d6
      
          That patch is included in slapos.core 1.3.15, but as we currently
          have a lot of older slapos.core deployed (e.g. 1.3.5 on my
          development webrunner) a workaround is (hopefully temporarily) used
          to pass non-ascii values as URL-encoded strings.

    • gitlab: Publish connection URL · 3c445ad3
      In the previous patch we setup nginx service which listens to the world
      and as such gitlab service becomes to be ready to used - so publish
      backend URL.
      
      NOTE we'll need to optimise and tweak gitlab a bit further in upcoming
          patches, so it can be really used under load and with our use-cases,
          but even now it listens to http ok and generally works.

    • gitlab/nginx: Slapos'ify config and turn nginx into a service · 85f7d7e3
      Go through nginx configuration templates and convert them to jinja2 with
      slapos parameters (reminder: names and default values are imported from
      omnibus-gitlab 8.2.3+ce.0-0-g8eda093), except commenting out features we
      do not want to support (yet ?).
      
      As nginx is a reverse-proxy, i.e. it integrates all internal services
      and works as frontend to them, our gitlab service is now ready to listen
      and talk to the world over (standard to slapos services backend) IPv6.
      
      Nginx also acts as SSL termination point - for it to work by default we
      setup self-signed certificate for the backend, which can be manually
      changed to proper certificate if needed. Backend certificate is used
      if gitlab is configured to work in HTTPS mode (and frontend certificate
      is another story).
      
      NOTE ssl certificate is generated with just `openssl req ...` - yes, there
          is slapos.cookbook:certificate_authority.request but it requires
          to start whole service and has up to 60 seconds latency to generate
          certificate. And we only need to run 1 command to do that...
      
      The features disabled are:
      
          - http -> https redirection
      
            not needed for us at nginx level - the frontend can do the
            redirection and also gitlab speaks HSTS on https port so when we access
            https port via http protocol, it gets redirected to https.
      
          - kerberos
          - ssl_dhparam
          - providing custom nginx configuration via instance parameter

    • gitlab: Import nginx http configuration from omnibus-gitlab · 61544d87
      Like with Rails configuration this first step is pristine import of
      nginx configuration files from omnibus-gitlab. All files were imported
      as-is in their ERB form and filenames from omnibus-gitlab
      8.2.3+ce.0-0-g8eda093 from here:
      
          https://gitlab.com/gitlab-org/omnibus-gitlab/tree/8eda093/files/gitlab-cookbooks/gitlab/templates/default
      
      We import only nginx main http configuration - nginx's CI and Mattermost
      configurations are not imported, as we do not support CI and Mattermost (yet ?).
      
      As with Rails configuration files, we will convert the templates to
      jinja2 and adjust them to slapos version in the following patches.  We
      will also use the same (commit from last-erb-mod commit + merge)
      approach to track upstream changes.

    • gitlab: Setup sidekiq service · 4c127fdd
      Sidekiq[1] is used in GitLab as background jobs manager - i.e. if a
      request handler needs to spawn some non-light job - it adds it to
      sidekiq queue (in Redis) and relies on sidekiq service to later pick
      this job up and execute it.
      
      The service is setup with just to run bin/gitlab-sidekiq with
      appropriate queues (extracted from omnibus-gitlab) and appropriate
      settings to controlling GitLab's sidekiq Out-Of-Memory killer[2].
      
      NOTE Unlike unicorn OOM killer, Sidekiq memory killer just makes sidekiq
          processes to be SIGKILL terminated and relies on managing service to
          restart it. In slapos we don't have mechanism to set autorestart=true,
          nor bang/watchdog currently work with slapproxy, so we setup to do
          such monitoring ourselves manually with here-introduced
          watcher-sigkill program.
      
      NOTE2 sidekiq promise, because it is rake/gitlab based, is slow to
          load/run and thus is put into etc/promise.slow/
