CreateJunction and DeletePath are now more
resilient to errors:
- CreateJunction opens the junction path to check
its target requesting fewer rights and with
greater sharing permission. This way it can
check junction targets even if the junction name
is opened by another process with no sharing.
- DeletePath attempts to call FindFirstFileW if
GetFileAttributesW fails with
ERROR_ACCESS_DENIED. There's hardly any info
about this error mode online, except for a code
comment in the .NET CoreFX library. (See new
code comments in this commit.)
Also:
- Change the error codes for DeletePath.
- Wrap the DeletPath error codes in a struct for
better readability.

The owning labels are the labels of the top-level configured targets that requested this artifact to be built (there may be many such targets). In cases where the artifact is added not through a configured target (build-info artifacts and coverage artifacts), the label of the artifact's owner is used.

contain a large set of files required for a particular toolchain that are added
to every single compile action. Some exeutors in turn sort all action inputs in
order to properly cache, deduplicate and serialize them.
Sorting the expansion of these middlemen needs to be done only once and a later
sorting together with a bunch of other action input files is much faster (as
Java's TimSort algorithm is effectively linear with mostly sorted inputs).

This change allows local files referenced by the BEP/BES protocol
to be uploaded to a ByteStream gRPC service.
The ByteStreamUploader is now implicitly also used by the BES
module which has a different lifecycle than the remote module.
We introduce reference counting to ensure that the channel is
closed after its no longer needed. This also fixes a bug where
we currently leak one socket per remote build until the Bazel
server is shut down.

Refactor handling of API generation in JavaPluginInfoProvider
Instead of keeping two copies of state for the API-generating and
non-API-generating cases, create a 'JavaPluginInfo' abstraction to contain all
state for each case, and then keep two copies in the top-level
JavaPluginInfoProvider provider.
This will make it easier and less error-prone to add additional state to the
provider.

than the graph version when that is feasible.
* It's not feasible when the computation accesses outside state, i.e. is non-hermetic, so see below.
* It's also more complicated (and not worth the trouble) when the computation is taking place just for the error status.
Have SkyFunctionName declare whether the function it corresponds to is hermetic or non-hermetic. Only non-hermetically-generated SkyValues can be directly marked changed, and non-hermetic SkyFunctions have their values saved at the graph version, not the max of the child versions. All SkyFunctions are hermetic except for the ones that can be explicitly dirtied.
A marked-hermetic SkyFunction that has a transient error due to filesystem access can be re-evaluated and get the correct version: if it throws an IOException at version 1 and then, when re-evaluated at version 2 with unchanged dependencies, has a value, the version will be version 1.
All Skyframe unit tests that were doing non-hermetic things to nodes need to declare that those nodes are non-hermetic. I tried to make the minimal set of changes there, so that we had good incidental coverage of hermetic+non-hermetic nodes. Also did some drive-by clean-ups around that code.
Artifacts are a weird case, since they're doing untracked filesystem access (for source directories). Using max(child versions) for them gives rise to the following correctness bug: 1. do a build at v1 that creates a FileStateValue for dir/ at v1. Then at v2, add a file to dir/ and do a build that consumes dir/ as a source artifact. Now the artifact for dir/ will (incorrectly) have v1. Then at v1, do that build again. We'll consume the "artifact from the future". However, this can only have an effect when using the local action cache, since the incorrect value of the artifact (the mtime) is only consumed by the action cache. Bazel is already broken in this way (incremental builds don't invalidate directories), so this change doesn't make things worse.

FilesetOutputSymlink whenever available.
In this change I'm simply plumbing the FileArtifactValue we requested within RecursiveFilesystemTraversalFunction to the FilesetOutputSymlink.
This does not work when the targets are output directories (or symlink to output dirs). The main scenarios this happens is when:
1. Fileset depends on the output dir created by a genrule.
2. Fileset depends on a GoAppengineBinary which creates an output dir.
3. Fileset depends on another Fileset in the non-recommended way (Fileset.entry.files = [<another_fileset>]) instead of the recommended way (FilesetEntry.srcdir = <another_fileset>).

- Previously we would zip the output of dsymutil and then proceed to unzip it.
Due to the size of dSYM files, this could add a few seconds to all builds
with dSYMs.
- There's no need to have a DsymOutputType or even Info.plist as all we need
is the DWARF symbol file; the dSYM is repackaged later on by the bundler.
This change is synchronized with the CROSSTOOL and wrapped_clang via the
`no_dsym_create_zip` feature, which Bazel sets on the CROSSTOOL to inform
wrapped_clang that no zip file should be created for the dSYM.

Calculating the throughput of a digest operation and using it to assess whether
I/O is slow or not only makes sense when we're doing sequential I/O. With
parallel hashing, it's expected that individual operations are slow due to how
the scheduler works, but it doesn't mean that the overall progress is slow.

Refocus synchronization mechanism to cope with file descriptor set fork-
induced races to more tightly constrain concurrent fork/exec pairs. This
problem has been observed in bazel proper repeatedly, exhibiting as the
iconic ETXTBSY - Text file busy in wide worker pool builds and tests.
Evidence that this was discovered by @buchgr is in the comment and change
to the embedded ExecutionService implementation, and the description of
the race and the need for the synchronization was lifted from that scope
to the JavaSubprocessFactory. This factory is a singleton and represents
the gateway to all worker process execution, and serves as the correct
lock primitive to ensure that file descriptor sets are not duplicated
across forks, which gave rise to this issue.
To test this, I demonstrated a reproducer presented at
https://bugs.java.com/view_bug.do?bug_id=8068370
with 2.4% of invocations in that pathological case exhibiting the issue.
With a functionally equivalent change - synchronizing around a
processBuilder.start() call - as the only modification to the reproducer,
no further failures of any kind were observed, over several hundred runs.
Closes #5556.

compose a nested set encompassing both). The current prunableHeaders were used
in various places, at least two of which let to a duplicate iteration through
the comparatively large declaredIncludeSrcs: CppCompileAction.computeKey() and
CppCompileAction.getAllowedDerivedInputs().
Also do some other minor optimizations:
- CcCompileActionBuilder.buildAllInputs() now just returns a NestedSet with the
same order as its parameter. As inputsForValidation is almost always empty,
this makes this NestedSet pass the underlying one through.
- CcCompilationContext.directModuleMaps is just a list of the module maps of
direct dependencies. As such, there is no use for keeping them in a
NestedSet.

commit 59f17d6e0550bf63a0b6ef182e2d63474e058ede updated files to use
try-with-resources when dealing with streams.
The change also got rid of asByteSource, replacing
it with throw-away ByteSource instances wrapping a
try-with-resources-guarded InputStream. Doing so
was unnecessary though, because all ByteSource
methods (except for open[Buffered]InputStream)
close the stream. Thanks to @jbduncan to point
that out and explain in detail [1].

Follow-up to commit 09d20311d982606093ed881d779bb05a5ee70ed3.
Use try-with-resources to ensure Writer objects
are closed eagerly.
Eagerly closing Writers avoids hanging on to
file handles until the garbage collector finalizes
the object, meaning Bazel on Windows (and
other processes) can delete or mutate these files.
Hopefully this avoids intermittent file deletion
errors that sometimes occur on Windows.

- Don't use NestedSets of NestedSets. Not sure whether this is a performance
improvement or has serialization benefits, but it does make understanding the
structure a lot easier.
- Use the same large NestedSet for all header information (whether or not they
are modular and what pregrepped headers might exist). This speeds up the
include scanner calls getLegalGeneratedScannerFileMap and getModularHeaders
because they now iterate over just a single NestedSet and the second
evaluation of a NestedSet is much cheaper. In a subsequent change, we can
likely fold all three iterations over this NestedSet into one (in
getLegalGeneratedScannerFileMap, getModularHeaders and getUsedModules).
Measurements show a small reduction in heap usage.
