Working on ori

Getting Dependencies

• install go 1.18 https://go.dev/doc/install

• If on windows, install mingw-gcc. This is to support building libsass on windows https://github.com/wellington/go-libsass/issues/37

  There are two ways to do this right now:

  1. Via Chocolatey:

     • Install Chocolatey
     • Install mingw from chocolatey choco install mingw. At time of writing this installs mingw 11.2.0.07112021

  2. Manually: do this only if you encounter issues with the version distributed by chocolatey:

     • Get a build from https://www.mingw-w64.org/downloads/#mingw-builds (the sourceforge link)
     • If the live installer fails, you can download the prebuilt binaries directly and add those to your path https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/
     • Prebuilt binaries require 7zip to extract https://www.7-zip.org/
     • I installed x86_64-posix-seh

• Add the path of mingw-gcc's bin to your path (in my case /c/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin)

• (Optional, but recommended) Install the go vscode plugin, and click "Install All" when it prompts you to install missing golang components (godef, gopkgs, gopls)

Running ori from this repo

1. Set up a ori.json and patches directory in your target project.

   See above for the ori.json fields

   TODO: document the patches directory

   TODO: make a an example of an oribuild project + config (#10)

2. Building and Running

   cd oribuild
   go run . -c ../path/to/ori.json`
   

   The first time you run this, go will fetch and build all the dependencies in oribuild/go.mod

Catches

Add more here as you hit unexpected situations

• in client-web: yarn gulp gqlgen:generate needs to be run manually after any graphql change.

• node_modules are not monitored and assumed to be always stable. If you edit node_modules, you will need to save another file to refresh. Once separate builds are implemented (#8), you will have to restart the whole build agent, unless you specifically omit that node_module from the build cache

• ori exits with error 0xc0000139 on windows

  $ go run . -h
  exit status 0xc0000139
  

  This translates to STATUS_ENTRYPOINT_NOT_FOUND https://pkg.go.dev/golang.org/x/sys/windows

  This might mean you have the wrong mingw install version and windows can't find the entrypoint symbols for the libsass binary at runtime? not 100% sure but changing the mingw version to the one specified above fixes the issue.

Useful Snippets

# with mingw on your path

# Build entries
go run . -config=../ori.json

# Build an entry named "OWA Mail" from the entrypoints map, with codesplitting
# Note that this has to be loaded with a script type="module" entrypoint,
# since esbuild codesplitting forces esm modules
go run . -config=../ori.json -entry="OWA Mail" -split

# Generate a cpu profile for initial and incrmental builds (the traces directory must already exist)
go run . -config=../ori.json -entry="OWA Mail" -traceInitialBuild -traceIncrementalBuilds -cpuprofile=traces/cpu.pprof

# Analyse cpu profiles (constains overview of CPU time)
go tool pprof -http=localhost:8080 traces/cpu.pprof.initial*
go tool pprof -http=localhost:8080 traces/cpu.pprof.incremental*

# Analyse traces
go tool trace traces/trace.out.*

# cutting a new release, from root dir
# first, update the version numbers in js/packages/oribuild/package.json,
# and update the dependency versions to the same version number.
git commit -m "bump to 0.0.0-pre-alpha.4"
git tag v0.0.0-pre-alpha.4
git push
git push --tags
# this reads the version numbers from js/packages/oribuild/package.json
# and generates new packages.
./scripts/build-nonmac.sh
# this publishes to npm (you'll have to npm login separately)
./scripts/publish-nonmac.sh

FAQs

• Why not use the esbuild node API?

  In short, we tried it and it was slow. Initial build times were several minutes, compared to the 40-odd seconds we see with the go api because of all the time plugins spent waiting to run on the node main thread.

• Can I customize ori for my monorepo?

  For now, ori will remain extremly opinionared on what the monorepo shape must look like. As much as possible, we want to prefer convention over configuration.

  In the same vein, rather than implementing plugins or encouraging people to fork and make their own custom builds of ori, new functionality will be added to the same ori binaries as needed.

• Why is it called ori?

  ori was started by the Outlook Web team, and is short for OWA Rapid Innerloop.

  It can also be easily typed on a single row of a QWERTY keyboard without using your fifth fingers, which I value because I have ulnar neuropathy.
