Functions to work with Miniconda python environment.

See http://conda.pydata.org/miniconda.html

class CondaApi(RecipeApi):

def install(self, version, path):

Downloads Miniconda installer for given version and executes it.

Args: version: version of Miniconda to install, e.g. ‘Miniconda2-3.18.3’. path: prefix to install Miniconda into.

Returns: Instance of CondaEnv, that also optionally acts as context manager that deletes the environment on exit.

recipe_modules / infra_checkout

DEPS: depot_tools/bot_update, depot_tools/gclient, depot_tools/git, depot_tools/presubmit, infra_system, recipe_engine/buildbucket, recipe_engine/context, recipe_engine/file, recipe_engine/json, recipe_engine/path, recipe_engine/platform, recipe_engine/python, recipe_engine/raw_io, recipe_engine/step

class InfraCheckoutApi(RecipeApi):

Stateless API for using public infra gclient checkout.

def checkout(self, gclient_config_name, patch_root=None, path=None, internal=False, named_cache=None, generate_env_with_system_python=False, **kwargs):

Fetches infra gclient checkout into a given path OR named_cache.

Arguments:

  • gclient_config_name (string) - name of gclient config.

  • patch_root (path or string) - path inside infra checkout to git repo in which to apply the patch. For example, ‘infra/luci’ for luci-py repo. If None (default), no patches will be applied.

  • path (path or string) - path to where to create/update infra checkout. If None (default) - path is cache with customizable name (see below).

  • internal (bool) - by default, False, meaning infra gclient checkout layout is assumed, else infra_internal. This has an effect on named_cache default and inside which repo's go corner the ./go/env.py command is run.

  • named_cache - if path is None, this allows to customize the name of the cache. Defaults to PUBLIC_NAMED_CACHE or INTERNAL_NAMED_CACHE, depending on internal argument value. Note: your cr-buildbucket.cfg should specify named_cache for swarming to prioritize bots which actually have this cache populated by prior runs. Otherwise, using named cache isn't particularly useful, unless your pool of builders is very small.

  • generate_env_with_system_python uses the bot “infra_system” python to generate infra.git‘s ENV. This is needed for bots which build the “infra/infra_python/${platform}” CIPD packages because they incorporate the checkout’s VirtualEnv inside the package. This, in turn, results in the CIPD package containing absolute paths to the Python that was used to create it. In order to enable this madness to work, we ensure that the Python is a system Python, which resides at a fixed path.

    No effect on arm64 because the arm64 bots have no such python available.

  • kwargs - passed as is to bot_update.ensure_checkout.

Returns: a Checkout object with commands for common actions on infra checkout.

recipe_modules / infra_cipd

DEPS: recipe_engine/buildbucket, recipe_engine/context, recipe_engine/json, recipe_engine/python, recipe_engine/runtime, recipe_engine/step

recipe_modules / support_3pp

DEPS: depot_tools/git, depot_tools/osx_sdk, depot_tools/windows_sdk, recipe_engine/archive, recipe_engine/buildbucket, recipe_engine/cipd, recipe_engine/context, recipe_engine/file, recipe_engine/json, recipe_engine/path, recipe_engine/platform, recipe_engine/python, recipe_engine/raw_io, recipe_engine/runtime, recipe_engine/step

Allows uniform cross-compiliation, version tracking and archival for third-party software packages (libs+tools) for distribution via CIPD.

The purpose of the Third Party Packages (3pp) recipe/module is to generate CIPD packages of statically-compiled software for distribution in our continuous integration fleets, as well as software distributed to our develepers (e.g. via depot_tools).

Target os and architecture uses the CIPD “${os}-${arch}” (a.k.a. “${platform}”) nomenclature, which is currently defined in terms of Go's GOOS and GOARCH runtime variables (with the unfortunate exception that CIPD uses ‘mac’ instead of ‘darwin’). This is somewhat arbitrary, but has worked well so far for us.

Package Definitions

The 3pp module loads package definitions from a folder containing subfolders. Each subfolder defines a single software package to fetch, build and upload. For example, you might have a folder in your repo like this:

my_repo.git/
  3pp/  # "root folder"
    .vpython             # common vpython file for all package scripts
    zlib/                # zlib "package folder"
      3pp.pb             # REQUIRED: the Spec.proto definition for zlib
      install.sh         # a script to build zlib from source
      extra_resource_file
    other_package/
      3pp.pb             # REQUIRED
      fetch.py           # a script to fetch `other_package` in a custom way
      install.sh
      install-win.sh     # windows-specific build script
    ...

This defines two packages (zlib, and other_package). The 3pp.pb files have references to the fetch/build scripts, and describe what dependencies the packages have (if any).

NOTE: Only one layer of package folders is supported currently.

Packages are named by the folder that contains their definition file (3pp.pb) and build scripts. It's preferable to have package named after software that it contains. However, sometimes you want multiple major versions of the software to exist side-by-side (e.g. pcre and pcre2, python and python3, etc.). In this case, have two separate package definition folders.

Each package folder contains a package spec (3pp.pb), as well as scripts, patches and/or utility tools to build the software from source.

The spec is a Text Proto document specified by the spec.proto schema.

The spec is broken up into two main sections, “create” and “upload”. The create section allows you to specify how the package software gets created, and allows specifying differences in how it's fetched/built/tested on a per-target basis, and the upload section has some details on how the final result gets uploaded to CIPD.

Creation Stages

The 3pp.pb spec begins with a series of create messages, each with details on on how to fetch+build+test the package. Each create message contains a “platform_re” field which works as a regex on the ${platform} value. All matching patterns apply in order, and non-matching patterns are skipped. Each create message is applied with a dict.update for each member message (i.e. [‘source’].update, [‘build’].update, etc.) to build a singular create message for the current target platform. For list values (e.g. ‘tool’, ‘dep’ in the Build message), you can clear them by providing a new empty value (e.g. tool: "")

Once all the create messages are merged (see schema for all keys that can be present), the actual creation takes place.

Note that “source” is REQUIRED in the final merged instruction set. All other messages are optional and have defaults as documented in spec.proto.

The creation process is broken up into 4 different stages:

  • Source
  • Build
  • Package
  • Verify
Envvars

All scripts described below are invoked with the following environment variables set:

  • $_3PP_PACKAGE_NAME - the name of the package currently building
  • $_3PP_PATCH_VERSION - the patch_version set for the version we're building (if any patch version was set).
  • $_3PP_PLATFORM - the platform we're targeting
  • $_3PP_TOOL_PLATFORM - the platform that we‘re building on (will be different than _3PP_PLATFORM if we’re cross-compiling)
  • $_3PP_VERSION - the version we're building, e.g. 1.2.3
  • $GOOS - The golang OS name we're targeting
  • $GOARCH - The golang architecture we're targeting
  • $MACOSX_DEPLOYMENT_TARGET - On OS X, set to 10.10, for your semi-up-to-date OS X building needs. This needs to be consistently set for all packages or it will cause linker warnings/errors when linking in static libs that were targeting a newer version (e.g. if it was left unset). Binaries built with this set to 10.10 will not run on 10.9 or older systems.

Additionally, on cross-compile environments, the $CROSS_TRIPLE environment variable is set to a GCC cross compile target triplet of cpu-vendor-os.

Source

The source is used to fetch the raw sources for assembling the package. In some cases the sources may actually be binary artifacts (e.g. prebuilt windows installers).

The source is unpacked to a checkout directory, possibly in some specified subdirectory. Sources can either produce the actual source files, or they can produce a single archive file (e.g. zip or tarball), which can be unpacked with the ‘unpack_archive’ option. In addition, patches can be applied to the source with the ‘patch_dir’ option (the patches should be in git format-patch format, and will be applied with git apply).

  • git - This checks out a semver tag in the repo.
  • cipd - This fetches data from a CIPD package.
  • script - Used for “weird” packages which are distributed via e.g. an HTML download page or an API. The script must be able to return the ‘latest’ version of its source, as well as to actually fetch a specified version. Python fetch scripts will be executed with vpython, and so may have a .vpython file (or similar) in the usual manner to pull in dependencies like requests.

Additionally the Source message contains a patch_version field to allow symver disambiguation of the built packages when they contain patches or other alterations which need to be versioned. This string will be joined with a ‘.’ to the source version being built when uploading the result to CIPD.

Build

The build message allows you to specify deps, and tools, as well as a script install which contains your logic to transform the source into the result package.

Deps are libraries built for the target ${platform} and are typically used for linking your package.

Tools are binaries built for the host; they‘re things like automake or sed that are used during the configure/make phase of your build, but aren’t linked into the built product. These tools will be available on $PATH (both ‘$tools’ and ‘$tools/bin’ are added to $PATH, because many packages are set up with their binaries at the base of the package, and some are set up with them in a /bin folder)

Installation occurs by invoking the script indicated by the ‘install’ field (with the appropriate interpreter, depending on the file extension) like:

<interpreter> "$install[*]" "$PREFIX" "$DEPS_PREFIX"

Where:

  • The current working directory is the base of the source checkout w/o subdir.
  • $install[*] are all of the tokens in the ‘install’ field.
  • $PREFIX is the directory which the script should install everything to; this directory will be archived into CIPD verbatim.
  • $DEPS_PREFIX is the path to a prefix directory containing the union of all of your packages' transitive deps. For example, all of the headers of your deps are located at $DEPS_PREFIX/include.
  • All tools are in $PATH

If the ‘install’ script is omitted, it is assumed to be ‘install.sh’.

If the ENTIRE build message is omitted, no build takes place. Instead the result of the ‘source’ stage will be packaged.

During the execution of the build phase, the entire ‘root folder’ is copied into the source checkout in the .3pp directory, and the script will be invoked as /path/to/checkout/.3pp/$package_name/$script_name. Because the entire root folder is copied, you can have shared resources (like .vpython files or helper scripts) which are common to all package definitions and located relative to the install script.

Package

Once the build stage is complete, all files in the $PREFIX folder passed to the install script will be zipped into a CIPD package.

It is strongly recommended that if your package is a library or tool with many files that it be packaged in the standard POSIXey PREFIX format (e.g. bin, lib, include, etc.). If your package is a collection of one or more standalone binaries, it's permissible to just have the binaries in the root of the output $PREFIX.

If the build stage is skipped (i.e. the build message is omitted) then the output of the source stage will be packaged instead (this is mostly useful when using a ‘script’ source).

Verify

After the package is built it can be optionally tested. The recipe will run your test script in an empty directory with the path to the packaged-but-not-yet-uploaded cipd package file and it can do whatever testing it needs to it (exiting non-zero if something is wrong). You can use the cipd pkg-deploy command to deploy it (or whatever cipd commands you like, though I wouldn't recommend uploading it to CIPD, as the 3pp recipe will do that after the test exits 0).

Additionally, vpython for the tool platform will be guaranteed to be in $PATH.

Upload

Once the test comes back positive, the CIPD package will be uploaded to the CIPD server and registered with the prefix indicated in the upload message. The full CIPD package name is constructed as:

<prefix>/<pkg_name>/${platform}

So for example with the prefix infra, the bzip2 package on linux-amd64 would be uploaded to infra/bzip2/linux-amd64 and tagged with the version that was built (e.g. version:1.2.3.patch_version1).

You can also mark the upload as a universal package, which will:

  • Omit the ${platform} suffix from the upload name
  • Set the target platform for the package to linux-amd64, regardless of what platform you build the recipe on. This was chosen arbitrarially to ensure that “universal” packages build consistently. You can override this behavior (and bypass the normal docker environment entirely) by setting the no_docker_env flag to true in your Create.Build message.

Versions

Every package will try to build the latest identifiable semver of its source, or will attempt to build the semver requested as an input property to the 3pp recipe. This semver is also used to tag the uploaded artifacts in CIPD.

Because some of the packages here are used as dependencies for others (e.g. curl and zlib are dependencies of git, and zlib is a dependency of curl), each package used as a dependency for others should specify its version explicitly (currently this is only possible to do with the ‘cipd’ source type). So e.g. zlib and curl specify their source versions, but git and python float at ‘head’, always building the latest tagged version fetched from git.

When building a floating package (e.g. python, git) you may explicitly state the symver that you wish to build as part of the recipe invocation.

The symver of a package (either specified in the package definition, in the recipe properties or discovered while fetching its source code (e.g. latest git tag)) is also used to tag the package when it's uploaded to CIPD (plus the patch_version in the source message).

Cross Compilation

Third party packages are currently compiled on linux using the ‘infra.tools.dockerbuild’ tool from the infra.git repo. This uses a slightly modified version of the dockcross Docker cross-compile environment. Windows and OS X targets are built using the ‘osx_sdk’ and ‘windows_sdk’ recipe modules, each of which provides a hermetic (native) build toolchain for those platforms.

For linux, we can support all the architectures implied by dockerbuild, including:

  • linux-arm64
  • linux-armv6l
  • linux-mips32
  • linux-mips64
  • linux-386
  • linux-amd64

Dry runs / experiments

If the recipe is run with force_build it will always build all packages indicated (and their dependencies), and will not upload any of them to the central server.

The recipe must always be run with a package_prefix (by assigning to the .package_prefix property on the Support3ppApi). If the recipe is run in experimental mode, ‘experimental/’ will be prepended to this. Additionally, you may specify experimental: true in the Create message for a package, which will have the same effect when running the recipe in production (to allow adding new packages or package/platform combintations experimentally).

Examples

As an example of the package definition layout in action, take a look at the 3pp folder in this infra.git repo.

Caches

This module uses the following named caches:

  • 3pp_cipd - Caches all downloaded and uploaded CIPD packages. Currently tag lookups are performed every time against the CIPD server, but this will hold the actual package files.
  • osx_sdk - Cache for depot_tools/osx_sdk. Only on Mac.
  • windows_sdk - Cache for depot_tools/windows_sdk. Only on Windows.

class Support3ppApi(RecipeApi):

def ensure_uploaded(self, packages=(), platform='', force_build=False):

Executes entire {fetch,build,package,verify,upload} pipeline for all the packages listed, targeting the given platform.

Args:

  • packages (seq[str]) - A sequence of packages to ensure are uploaded. Packages must be listed as either ‘pkgname’ or ‘pkgname@version’. If empty, builds all loaded packages.
  • platform (str) - If specified, the CIPD ${platform} to build for. If unspecified, this will be the appropriate CIPD ${platform} for the current host machine.

Returns (list[(cipd_pkg, cipd_version)], set[str]) of built CIPD packages and their tagged versions, as well as a list of unsupported packages.

def initialize(self):

def load_packages_from_path(self, path):

Loads all package definitions from the given path.

This will parse and intern all the 3pp.pb package definition files so that packages can be identified by their name. For example, if you pass:

path/ pkgname/ 3pp.pb install.sh

This would parse path/pkgname/3pp.pb and register the “pkgname” package.

Args:

  • path (Path) - A path to a directory full of package definitions. Each package definition is a directory containing at least a 3pp.pb file, whose behavior is defined by 3pp.proto.

Returns a set(str) containing the names of the packages which were loaded.

Raises a DuplicatePackage exception if this function encounters a package whose name is already registered. This could occur if you call load_packages_from_path multiple times, and one of the later calls tries to load a package which was registered under one of the earlier calls.

def package_prefix(self, experimental=False):

Returns the CIPD package name prefix (str), if any is set.

This will prepend ‘experimental/’ to the currently set prefix if:

  • The recipe is running in experimental mode; OR
  • You pass experimental=True

def set_package_prefix(self, prefix):

Set the CIPD package name prefix (str).

All CIPDSpecs for built packages (not sources) will have this string prepended to them.

Recipe to build CIPD package with sealed Conda environment.

Supposed to be used from manually triggered Buildbot builders. We aren't expecting rebuilding this environment often, so setting up and periodic schedule is a waste of resources.

To build a new package for all platforms:

  1. Manually trigger all builders by clicking buttons in Buildbot.
  2. Once they all complete, tag the with some release identifier by running: ./cipd set-tag infra/conda_python/scientific/ -tag=release: -version=latest
  3. Update Puppet configs to use ‘release:’ as a version.

See if we can avoid running the rest of the recipe, if there's no new commits to incorporate into the mirror. We should be conservative in the direction of “True” - the worst case is we update the mirror without any new commits, which will generate a new synthetic commit (with a different hash due to a different timestamp) at the same underlying commit. Unnecessary, but harmless.

Imports changes from web-platform-tests into Chromium.

This recipe runs the wpt-import script. The import process involves first fetching the latest changes from web-platform-tests, then running the tests via try jobs and and updating any baselines and expectations, before committing to Chromium.
