Before, we'd open files and feed bytes to yaml.load(). When a str
is fed to yaml.load(), it attempts to guess the encoding. It defaults
to UTF-8 unless somebody set us up the BOM. This is probably OK.
Except if the file isn't valid UTF-8, the exception will be raised
in the bowels of YAML parsing and it may not be obvious the failure
is due to invalid UTF-8 input versus say Python str/unicode
coercion foo.
We change all call sites that load YAML from a file to use
codecs.open() to open the file in UTF-8 and perform UTF-8
decoding/validation at file read time. This should make any UTF-8
failures more obvious. Furthermore, it reinforces that our YAML files
are UTF-8 and not some other encoding.
I discovered this issue as part of trying to get emoji symbols to
render on Treeherder. Unfortunately, it appears pyyaml detects
many emoji as unprintable characters and refuses to load them. This
makes me sad and makes me want to abandon pyyaml/YAML in favor of
something that supports emoji :P

I was looking at some decision task logs and noticed lines like:
Connection pool is full, discarding connection: taskcluster
I also noticed lines like:
Starting new HTTP connection (153): taskcluster
In this case, we had established 153 TCP connections to a server.
Looking at the requests source code, a requests.session by default
creates a connection pool with capacity of 10. There are actually 2
components to the capacity: idle connections and active connections.
What appeared to be happening was we could obtain an idle connection,
use it, and then it would be discarded when put back in the idle
pool because the idle pool was at capacity. Furthermore, it also
appears that connections were sitting around waiting for a TCP
connection.
This commit uses a custom "adapter" with an increased pool size that
matches the concurrency level of the code issuing the HTTP requests.
This should increase the number of concurrent TCP connections / requests,
decreease the number of TCP connections being used overall, and make
decision tasks complete faster.

This commit does a lot. But it's really not too difficult to comprehend
once you focus on the final state, which is basically the same as the
"lint" image and derived tasks.
Before, the "decision" image contained a "checkout-gecko" script and
"run-action" and "run-decision" scripts. The latter 2 invoked the first
script.
The "run-task" script basically does what the combination of these
scripts were doing before. So we switch to it.
While we're here, we also replaced the custom Mercurial installation in
this image with the shared install-mercurial.sh script. The
system-setup.sh script for the decision image is now short and sweet.
The YAML files for tasks using this image have been updated to use
"run-task." We no longer have to pass an environment variable to hold
command arguments. So we revert to putting these arguments inline in
the task's command. Dustin never liked passing the arguments as
environment variables, so it should make him happy ;) We add
--log-no-times because "run-task" prefixes its own timestamps on output
lines.
The path to the Gecko checkout has been changed from
/home/worker/workspace to /home/worker/checkouts to match changes made
in bug 1289643.
Finally, since "checkout-gecko-and-run" is no longer used, we delete it.
The Docker image version has been bumped accordingly.

Now that Docker image building is called from Python, we can start to
do advanced stuff with it.
With this commit, we switch from building Docker images directly from
the source directory ("the Docker way") to using our custom Docker image
build contexts.
The main advantage of this is that locally-built Docker images can now
use our custom Dockerfile syntax to include extra files in the build
context!
The code for building a Docker image from a context has been extracted
to its own standalone function. I have nefarious plans for this in the
future, such as the ability to override the FROM syntax to specify
URLs of images. This would allow us to host base images on our own
server, which removes a dependency on Docker Hub and improves
determinism, since images on Docker Hub change all the time.

Docker image building will soon need to use Python in order to produce
the image build context archive.
As the first step towards this, we introduce a Python function that
calls out to build.sh. We also implement a mach command that calls it
so we can test the functionality.
I'm not keen about introducing a new mach command. I'd prefer to have
a sub-command instead. I'm not sure what all uses
`mach taskcluster-load-image`. Perhaps we could make a `taskcluster`
top-level command. Or perhaps we could fold these image commands into
`mach taskgraph`? Either way, the mach side of this isn't terribly
important to the commit series: most of the code will live inside a
Python module outside of mach.

Previously, the VCS checkout cache would be optimized away on Try. This
meant every task on Try had to create its own checkout from scratch. This
meant writing ~150,000 files. By allowing use of the cache, we minimize

Currently, the gecko-decision and action tasks maintain a separate cache
for each "project" (Firefox repo) source checkout. In my opinion, this
is not necessary.
Separate caches/source checkouts mean a lower chance for a cache hit:
a lower chance that any given worker will have a source checkout readily
available for the "project" being built. They also mean workers store
more data and files in caches.
By using a shared cache for source checkouts, workers will ideally
only have a single source checkout cache and will be pretty much
guaranteed to have a checkout readily available (the main exception
being the first task on a freshly-provisioned worker).
A downside of a shared cache is that workers may spend more time doing
`hg update` operations. e.g. if the last task was from mozilla-release
and the current task is from mozilla-central, thousands of files will
be updated. However, I believe we will still be better off because
separate caches *increase* the probability for a full checkout, which
involves writing ~150,000 files! So I believe this change will lower
the overall amount of VCS work done by workers while possibly
sacrificing the lowest possible execution time (which is achieved by
minimizing the `hg update` work).
It's worth noting that `hg robustcheckout` (which is used by these
tasks) does the equivalent of an `hg purge --all`. This ensures that all
untracked and ignored files from previous tasks are deleted. So there
should be no contamination from previous tasks.

The decision task configures a /home/worker/workspace cache. However,
the command we run in the container references a "workspace" relative
path. From logs in automation, it appears that PWD during execution
is "/" because "workspace" is being resolved to "/workspace." The

A limitation of traditional docker build context generation is it
only includes files from the same directory as the Dockerfile. When
repositories have multiple, related Dockerfiles, this limitation
results file duplication or putting all Dockerfiles in the same
directory (which isn't feasible for mozilla-central since they would
need to be in the root directory).
This commit enhances Dockerfiles to allow *any* file from the
repository checkout to be ADDed to the docker build context.
Using the syntax "# %include <path>" you are able to include paths
or directories (relative from the top source directory root) in the
generated context archive. Files add this way are available under the
"topsrcdir/" path and can be ADDed to Docker images.
Since context archive generation is deterministic and the hash of
the resulting archive is used to determine when images need to be
rebuilt, any extra included file that changes will change the hash
of the context archive and force image regeneration.
Basic tests for the new feature have been added.

This introduces a completely new way of specifying test task in-tree,
completely replacing the old spider-web of YAML files.
The high-level view is this:
- some configuration files are used to determine which test suites to run
for each test platform, and against which build platforms
- each test suite is then represented by a dictionary, and modified by a
sequence of transforms, duplicating as necessary (e.g., chunks), until
it becomes a task definition
The transforms allow sufficient generality to support just about any desired
configuration, with the advantage that common configurations are "easy" while
unusual configurations are supported but notable for their oddness (they
require a custom transform).
As of this commit, this system produces the same set of test graphs as the
existing YAML, modulo:
- extra.treeherder.groupName -- this was not consistent in the YAML
- extra.treeherder.build -- this is ignored by taskcluster-treeherder anyway
- mozharness command argument order
- boolean True values for environment variables are now the string "true"
- metadata -- this is now much more consistent, with task name being the label
Testing of this commit demonstrates that it produces the same set of test tasks for
the following projects (those which had special cases defined in the YAML):
- autoland
- ash (*)
- willow
- mozilla-inbound
- mozilla-central
- try:
-b do -p all -t all -u all
-b d -p linux64,linux64-asan -u reftest -t none
-b d -p linux64,linux64-asan -u reftest[x64] -t none[x64]
(*) this patch omits the linux64/debug tc-M-e10s(dt) test, which is enabled on
ash; ash will require a small changeset to re-enable this test.

The JSON output is suitable for processing with `jq` to extract features of
interest.

Currently, Gecko decision tasks spend ~8 minutes making HTTP requests to the
queue API. Let's throw a thread pool at it so tasks are submitted faster.
This could possibly be faster if there were a single batch submit API in
the queue. However, that isn't implemented for technical reasons described
in the bug.

* Implement & document optimization (although legacy kind doesn't do much of it)
* Introduce `optimize_target_tasks` parameter to control whether tasks in the
target set can be optimized (no for try, yes for most other branches)
* Refactor to include resolved taskIds in the optimized task graph
* Include a `label-to-taskid.json` artifact.
* Introduce {'task-reference': '... <dependency-name> ...'} for referring to
parent tasks' taskId.

This adds support for the `-t`/`--talos` option, matching such jobs against
`talos_try_name`. There are no such tasks just yet.

Currently, jobs which has 'file_patterns' set will only be run if a file matching one
of those patterns has been modified. This means that unless the task definition of the
job was explicitly included in those 'file_patterns', the job won't run when we modify
it!
I think it is safe to assume that when making changes to a job's task, we want it to be
run no matter what. So let's add the task definition to 'file_patterns' automatically.
Here's a try run which modifies the marionette harness task:

This monkey-patches the old taskcluster_graph code to avoid impacting branches
that are still using that support for decision graphs. All of this will go
away when docker image builds become their own kind.

The `taskgraph` package generates TaskCluster task graphs based on collections
of task "kinds". Initially, there is only one kind, the "legacy" kind, which
reads the YAML files from `testing/taskcluster/tasks` to generate the task
graph.
Try syntax is implemented by filtering the tasks in the taskgraph after it has
been created, then extending the result to include any prerequisite tasks.
A collection of `mach taskgraph` subcommands are provided for developers to
extend or debug the task-graph generation process.
