      erp5: ERP5 and Jupyter integrated together · 519a575d
      Kirill Smelkov authored
      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
      nexedi/erp5!29 and nexedi/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 nexedi/slapos!43 and nexedi/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
      Douglas authored
      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
      Kirill Smelkov authored
      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 (nexedi/erp5!29) which just got merged to erp5.git recently (see nexedi/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.

      wendelin: Remove bt5_list leftover · 9aa86470
      Kirill Smelkov authored
      @rafael added this in 971d0bb7 (erp5: Make possible extent the list of
      initial business templates to install), but we dropped that change while
      merging erp5-cluster to master - see:
      
          6bbb61a8 "Merge branch 'master' into erp5-cluster", and
          e84d5e83 "Merge branch 'erp5-cluster'"
      
      6bbb61a8 claimed that it
      
          Dropped commit 971d0bb7
          ("erp5: Make possible extent the list of initial business templates to install").
      
      but it actually dropped changes only under stack/erp5/ , not software/wendelin/
      
      Fix it.

      GitLab Software Release - first version · 866d9051
      Kirill Smelkov authored
      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
      Kirill Smelkov authored
      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
      Kirill Smelkov authored
      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
      Kirill Smelkov authored
      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
      Kirill Smelkov authored
      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.
