Build System Notes

CMake

1. Dependency binaries are pulled from Anaconda. CMake uses conda environment location to find packages.

2. Make targets can be listed with make help. Some convenience targets are:

   $ make help
   The following are some of the valid targets for this Makefile:
   ... .....
   ... .....
   ... PythonFiles
   ... test-rt
   ... test-py-compile
   ... test-verbose-broken
   ... test-progs
   ... test-verbose
   ... .....
   ... .....

3. libpython can be linked statically or dynamically when python is built. It is important for python extensions to be aware of the type of linking in order to avoid segfaults. This can be accomplished by querying Py_ENABLE_SHARED.

      1 python -c "import sysconfig; print(sysconfig.get_config_var('Py_ENABLE_SHARED'))"
   

   In EMAN, it is done in cmake/FindPython.cmake

4. OpenGL detection when Anaconda's compilers are used is done using a cmake toolchain file.

5. glext.h file needed for OpenGL related module compilation is already present on Linux and Mac. On Windows, it is manually copied once into C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\gl. On Appveyor it is downloaded as part of env setup every time a test is run.
6. Compiler warnings are turned off by default and can be turned on by setting ENABLE_WARNINGS=ON

      1 cmake <source-dir> -DENABLE_WARNINGS=ON
   

7. Setting compiler and linker options by include_directories, add_definitions that have global affects are avoided and target-focused design employing modern cmake concepts like interface libraries are used as much as possible.

Anaconda

Dependencies not available on anaconda or conda-forge are available cryoem. The binaries are built and uploaded using conda-forge's conda-smithy. conda-smithy takes care of generating feedstocks, registering them on GitHub and online CI services and building conda recipes.

Conda-smithy Workflow

Conda smithy uses tokens to authenticate with GitHub.

•    1 # conda-forge.yml
     2 
     3 channels:
     4   sources: [cryoem, defaults, conda-forge]
     5   targets:
     6   - [cryoem, main]
     7 
     8 github:
     9   user_or_org: cryoem
    10   repo_name: <package>-feedstock
    11 
    12 provider:
    13   linux: circle
    14   osx: travis
    15   win: appveyor
    16 
    17 azure:
    18   build_id: blank
  

     1 # recipe/conda_build_config.yaml
     2 
     3 channel_sources:
     4 - cryoem, defaults,conda-forge
     5 channel_targets:
     6 - cryoem dev
  

Conda-smithy commands:

•    1 conda create -n smithy conda-smithy
     2 conda activate smithy
     3 conda smithy init <recipe_directory>
     4 conda smithy register-github <feedstock_directory> --organization cryoem
     5 conda smithy register-ci --organization cryoem --without-azure --without-drone
     6 conda smithy rerender --no-check-uptodate
  

Continuous Integration

1. GitHub webhooks are setup to send notifications to blake. Blake forwards those to three build machines, although only Linux is sufficient. Linux runs the server that drives the the Jenkins jobs.

2. Binary builds on local build machines.

   1. Manually triggered by including "[ci build]" anywhere in the last commit message. Manually triggered builds on master branch are uploaded as continuous builds and builds triggered from any other branch are uploaded to testing area.

   2. Triggered by cron builds daily.

   3. Any branch in the form of "release-" triggers continuous builds without having to include "[ci build]" in the commit message. Once the release branch is ready, release binaries are manually copied from cont. builds folder into the release folder on the server.
3. CI configurations files:

   1. CircleCI: .circleci/config.yml

   2. TravisCI: .travis.yml

   3. Appveyor: appveyor.yml

   4. JenkinsCI: Jenkinsfile

      1. Secrets like ssh keys are stored locally in Jenkins
      2. Some env vars need to be set by agents:
         1. HOME_DIR, DEPLOY_PATH, PATH+EXTRA (to add miniconda to PATH).
         2. PATH+EXTRA is not set on win. (?)
            1. Now, it is set on win, too.

      3.  Launch method: via SSH
            Advanced:
              Prefix Start Agent Command: "D: && "

      4. On windows for sh calls in jenkins to work "Git for Windows" might need to be installed.

Jenkins Setup

1. Triggers

   1. GitHub webhooks

   2. Cron
   3. Binary build trigger
2. Jenkins master needs PATH prepended with $CONDA_PREFIX/bin
3. Jenkins Docker image, docker-coompose or docker stack deploy
4. docker-compose.yml at home dir in build machines

5. TZ: https://stackoverflow.com/a/46384925

6. plugins
7. config, jcasc, config.xml, users.xml, jobs/*.xml?, gpg encrypt
8. Agent nodes setup, agent nodes auto-start
9. Server and agent per machine vs single server and os agents
   1. Master only
   2. Master and agent per machine
   3. Single master and OS agents

Linux

Run as service: Open Task Manager(Ctrl+Shift+Esc), New task, Browse to agent.jnlp and run as admin does this work? This is when starting via Web Launcher doesn't work.

currently, task scheduler works need to have miniconda pn path, set it during miniconda installation, but do not(?) register python.

While installing miniconda register python and add to PATH. Then, conda init in cmd (git init cmd.exe) and git windows (git init bash). And, maybe restart???

BUG: miniconda3 conda-build=3.17.8 adds vc14 even if python2 is requested in build reqs
