This is the App Engine app that serves https://crashpad.chromium.org/. To work on this app, obtain the following packages: - Go, from https://golang.org/dl/. This is only necessary for local development and testing. The directory containing the “go” executable, such as /usr/local/go/bin, must appear in $PATH. It does not appear critical for the Go version used to match the Go runtime version used (for example, these instructions were tested with Go 1.14 locally but a Go 1.11 runtime when deployed), but if problems are encountered, it would be wise to use the same version for both local development and AppEngine deployment. - The Google Cloud SDK (gcloud CLI) from https://cloud.google.com/sdk/docs/install-sdk. This is necessary for both local development and for AppEngine deployment. Unpacking this package produces a google-cloud-sdk directory, whose bin child directory may be added to $PATH for convenience, although this is not strictly necessary. The commands in this README are expected to be run from the directory containing it. To test locally: % go get -d ./src/crashpad-home % python3 …/google-cloud-sdk/bin/dev_appserver.py src/crashpad-home dev_appserver.py must be invoked using Python 3, but internally will use Python 2, and a Python 2 interpreter must be available in the PATH as python2. Look for the “Starting module "default" running at: http://localhost:8080” line, which tells you the URL of the local running instance of the app. Test http://localhost:8080/ to ensure that it works. It would be good to test http://localhost:8080/doxygen as well, but it may fail with HTTP status 500 and the following error returned as the HTTP response body because memcache seems to not be available in the local dev_appserver environment: service bridge HTTP failed: Post "http://appengine.googleapis.internal:10001/rpc_http": dial tcp: lookup appengine.googleapis.internal: no such host The /doxygen URL can be tested in a verison of the app that’s been deployed before traffic has been migrated to it by visiting the staged deployed version from the App Engine console. To deploy: % version=$(git rev-parse --short=12 HEAD) % [[ -n "$(git status --porcelain)" ]] && version+=-dirty % …/google-cloud-sdk/bin/gcloud app deploy \ --project=crashpad-home --version="${version}" --no-promote \ "$(pwd)/src/crashpad-home" (Note: the $(pwd) is necessary for “gcloud app deploy” to recognize that the application is in GOPATH, putting it into “GOPATH mode”. This normally happens correctly on its own even with a relative path, but will fail for relative paths when $(pwd) is a symbolic link. Using an absolute path here will save you from this frustration, freeing you up to undoubtedly experience other frustrations.) Activate a newly-deployed version by visiting the App Engine console at https://console.cloud.google.com/appengine/versions?project=crashpad-home, selecting it, and choosing “Migrate Traffic”. It is also possible to delete old versions from this page when they are no longer needed.
