DummyTask needs the flag to correctly test task execution filters appropriately

It looks like the remaining failure is unrelated to the changes here - though I didn't catch it on other branches so there may be something I've missed. Errorpants.build_graph.address_mapper.AddressMapper.BuildFileScanError: PathGlobs expansion failed: While expanding link "z/w/y": Failed to read_link for Link("z/w/y"): Os { code: 2, kind: NotFound, message: "No such file or directory" } |

@codealchemy agreed. I found no existing flaky-test issues matching so I've snapshotted the full test failure and re-started the shard. If it goes green I'll file the flaky-test issue. |

commit efaae09 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 23:41:55 2019 -0700 Add debugging to release.sh for linux ucs2 It looks like the bootstrap part now works completely as intended! It's consistently using UCS2. But the release script is failing for some reason. Turn on debugging to wake up to hopefully some insight tomorrow morning.. commit 4cb6cae Author: Eric Arellano <[email protected]> Date: Tue Feb 26 18:27:22 2019 -0700 Squashed commit of the following: commit 9c754dc Merge: 3f30d39 7819724 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 17:17:34 2019 -0700 Merge branch 'master' of github.com:pantsbuild/pants into pex-interpreter-constraints commit 3f30d39 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 17:12:01 2019 -0700 Fix issue with compatibility_or_constraints() returning a tuple add_interpreter_constraints() expects a str, so we must unpack the tuple when calling it. commit ff17f73 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 22:46:16 2019 -0700 Revert "Constrain ci.sh to the exact Python interpreter version" This reverts commit 887a8ef. This change is necessary to fix the original motivation for this PR, but it does not really belong in this PR anymore. Instead, it should be in the Py2 ABI PR (7235). This PR should be kept more generic, and there is no logical connection to the changes being made with ci.sh, beyond that original motivating problem. commit 6b07abd Author: Eric Arellano <[email protected]> Date: Mon Feb 25 21:49:52 2019 -0700 Remove bad import My bad for not catching this before pushing. commit 2c6fdb0 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 21:37:41 2019 -0700 Generify solution by using compatibility_or_constraints() Instead of applying a bandaid for only `./pants binary`, John proposed fixing the issue with our PexBuilderWrapper itself. So, we use `compatibility_or_constrains()`, which will first try to return the target's compatibility, else will return the Python Setup subystem's value. The wrapper still is not ideal and John proposes killing add_interpreter_constraint() and add_interpreter_constraints_from() to instead automatically be setting the interpreter constraints from the targets graph. This PR does not make that change for the scope, but this should be noted. commit b71f164 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 21:03:46 2019 -0700 Fix typo commit 3bca020 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 20:31:14 2019 -0700 Add global interpreter constraints to Python binary creation commit 887a8ef Author: Eric Arellano <[email protected]> Date: Fri Feb 22 21:05:50 2019 -0700 Constrain ci.sh to the exact Python interpreter version Earlier we allowed the patch version to float. We discovered in pantsbuild#7235 with the CI run https://travis-ci.org/pantsbuild/pants/jobs/497208431#L891 that PEX was building with 2.7.10 but running with 2.7.13. The fix will require having Pants pass interpreter constraints to Pex. Even with that change though, the CI shard would still have the issue because the constraint would be floating. Now, we have the constraint be exact. commit 0d25bcc Merge: 373ffee 7819724 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 17:41:10 2019 -0700 Merge branch 'master' of github.com:pantsbuild/pants into py2-wheels-abi-specified commit 373ffee Author: Eric Arellano <[email protected]> Date: Tue Feb 26 17:39:25 2019 -0700 Configure PEX_PYTHON on linux UCS2 It looks like ./pants binary now completely builds the PEX with 2.7.15 / UCS2! But then when trying to run `./pants.pex -V`, it resolves the runtime interpreter to 2.7.13 :/ I'm not sure how the runtime interpreter selection is supposed to work, but there is an env var PEX_PYTHON that allows passing a path to the value you always want to use. So, we use this for now. commit 7819724 Author: Alex Schmitt <[email protected]> Date: Tue Feb 26 13:42:36 2019 -0800 Allow tasks to opt-in to target filtering (pantsbuild#7283) Followup to pantsbuild#7275 following [discussion](pantsbuild#7275 (comment)) that the target filter was being applied to tasks that do not support it (e.g. tasks that don't access targets via `get_targets()`) This adds a class property to `Task` that allows subclasses to effectively opt-in to the new behavior - and sets that flag to `True` for `fmt` and `lint` tasks. commit 3bf2d28 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 12:11:17 2019 -0700 Add Pyenv back to Travis path Even though we directly pass $PY, later processes expect the 2.7.15 interpreter to be discoverable so Pyenv must be on the path. commit 2166efe Author: Eric Arellano <[email protected]> Date: Tue Feb 26 09:52:10 2019 -0700 Set $PY to disambiguate which Py2.7 version to use Interpreter constraints don't work, as previously noted. commit 8dd215d Author: Eric Arellano <[email protected]> Date: Tue Feb 26 09:43:42 2019 -0700 Allow user to set $PY in ci.sh If not set, will resolve to the Python version being used. We should allow the user to set it though in cases like this PR, where we may have to set $PY to a very specific interpreter path. commit 49fe576 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 09:41:35 2019 -0700 Stop hardcoding interpreter constraints Let ci.sh determine them based on the $PY value. While working on the Linux UCS2 shard, it became clear that what really matters is which interpreter $PY (i.e. `python2`) resolves to. Setting the interpreter constraints will not impact what this resolves to nor how we bootstrap Pants. So, we should focus on setting $PY and let the interpreter constraints be resolved accordingly. commit c3dd843 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 08:49:44 2019 -0700 Improve wording. commit f810849 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 08:43:42 2019 -0700 Move interpreter constraints to Docker env entry Docker does not pull in external env vars. Instead, we must specify this in the Dockerfile. This change has added benefit that it moves all of the Py2 logic into the Dockerfile out of .travis.yml, and leaves .travis.yml solely to call the Dockerfile. commit b9efbf0 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 01:03:21 2019 -0700 Also set PANTS_PYTHON_SETUP_INTERPRETER_CONSTRAINTS for OSX Even though it was resolving correctly already, explicit is better than implicit. commit 8402c1f Author: Eric Arellano <[email protected]> Date: Tue Feb 26 01:01:03 2019 -0700 Ensure Linux UCS2 always uses Py2.7.15 (UCS2) It was not enough to install 2.7.15 and use Pyenv global. The 2.7.13 (UCS2) interpreter was still being recognized. commit 225f153 Author: Eric Arellano <[email protected]> Date: Tue Feb 26 00:53:56 2019 -0700 Remove bad merge lines commit 1be9e90 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 22:41:04 2019 -0700 Squashed commit of the following: commit 6b07abd Author: Eric Arellano <[email protected]> Date: Mon Feb 25 21:49:52 2019 -0700 Remove bad import My bad for not catching this before pushing. commit 2c6fdb0 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 21:37:41 2019 -0700 Generify solution by using compatibility_or_constraints() Instead of applying a bandaid for only `./pants binary`, John proposed fixing the issue with our PexBuilderWrapper itself.

We still keep them high up relative to others because several major workflows require wheel building output. commit 223541e Author: Eric Arellano <[email protected]> Date: Mon Feb 25 22:35:02 2019 -0700 Fix Linux UCS2 using 2.7.13 with UCS4 instead of UCS2 sometimes There were two versions of 2.7.13 installed on the system, so Pants would sometimes choose an unintended version and would be inconsistent. commit 8428376 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 21:03:22 2019 -0700 Fix typo from squashed pex-constraints commit 48ef4dd Author: Eric Arellano <[email protected]> Date: Mon Feb 25 20:44:37 2019 -0700 Squashed commit of the following: commit 3bca020 Author: Eric Arellano <[email protected]> Date: Mon Feb 25 20:31:14 2019 -0700 Add global interpreter constraints to Python binary creation commit 887a8ef Author: Eric Arellano <[email protected]> Date: Fri Feb 22 21:05:50 2019 -0700 Constrain ci.sh to the exact Python interpreter version Earlier we allowed the patch version to float.

This is because we have been patching together collections of these resources "by hand", without applying any higher-level structure (explicitly constructing each `path_entries` and `library_dirs` field for every executable, every time, for example). This was done to avoid creating abstractions that might break down due to the rapidly evolving code. We can now take the step of more clearly defining the relationships between the toolchains we construct hierarchically. ### Solution - Add an `ExtensibleAlgebraic` mixin which allows declaring list fields which can be immutably modified one at a time with `prepend_field` and `append_field`, or all at once with `sequence`. - Add a `for_compiler` method to `BaseLinker` to wrap the specific process required to prep our linker for a specific compiler. - Apply all of the above in `native_toolchain.py`. ### Result The compilers and linkers provided by `@rule`s in `native_toolchain.py` are composed with consistent verbs from `ExtensibleAlgebraic`, leading to increased readability. commit cd4c773 Author: Nora Howard <[email protected]> Date: Mon Feb 25 17:22:08 2019 -0700 [zinc-compile] fully adopt enum based switches for hermetic/not; test coverage (pantsbuild#7268) @cosmicexplorer wrote this as part of pantsbuild#7227. This patch is pulling out just the Zinc changes, with a few differences. I also added a new test for hermetic failures and some additional assertions to ensure that the right message is being communicated on failures, while doing that I discovered that hermetic/non-hermetic appear to produce error messages on different streams. commit c095f3b Author: Alex Schmitt <[email protected]> Date: Mon Feb 25 10:49:57 2019 -0800 Update TargetFiltering args for applying criteria (pantsbuild#7280) Update the class to take the criteria in the constructor, and helper methods take the targets against which to apply said criteria. From suggestion https://github.com/pantsbuild/pants/pull/7275\#discussion_r259554586 commit a87a01b Author: Danny McClanahan <[email protected]> Date: Fri Feb 22 18:53:52 2019 -0800 don't do a pants run on osx (pantsbuild#7278) ### Problem Fixes pantsbuild#7247, catching a case that was otherwise missed. ### Solution - Don't do a `./pants run` on osx using the gnu toolchain in testing, as it doesn't work yet. ### Result As noted in pantsbuild#7249, it's strange that that PR passes but the nightly job fails -- it may be nondeterministic. commit a86639e Author: Alex Schmitt <[email protected]> Date: Fri Feb 22 16:52:32 2019 -0800 Add filtering subsystem to permit skipping targets by tags (pantsbuild#7275) This subsystem is responsible for handling options meant to exclude targets from specific tasks The application of the logic itself is contained in the TargetFiltering class - which currently only handles excluding targets with provided tags and can be expanded upon for additional filtering options. commit b34d66f Author: John Sirois <[email protected]> Date: Fri Feb 22 16:46:32 2019 -0800 Prepare the 1.15.0.dev1 release. (pantsbuild#7277) commit 8069653 Author: Danny McClanahan <[email protected]> Date: Fri Feb 22 11:41:58 2019 -0800 cache python tools in ~/.cache/pants (pantsbuild#7236) ### Problem This runs for (on my laptop) about 16 seconds every time I do a `clean-all`: ``` 22:27:23 00:02 [native-compile] 22:27:23 00:02 [conan-prep] 22:27:23 00:02 [create-conan-pex] 22:27:39 00:18 [conan-fetch] ``` It doesn't seem like we need to be putting this tool in the task workdir as the python requirements list is pretty static. Conan in particular will be instantiated by invoking almost every goal, and it is a nontrivial piece of software to resolve each time. Also, we aren't mixing in interpreter identity to the generated pex filename, which is a bug that has so far gone undetected: see pantsbuild#7236 (comment). ### Solution - Take the `stable_json_sha1()` of the requirements of each python tool generated by `PythonToolPrepBase` to generate a fingerprinted pex filename. - Stick it in the pants cachedir so it doesn't get blown away by a clean-all. - Add an `--interpreter-constraints` option to pex tools (where previously the repo's `--python-setup-interpreter-constraints` were implicitly used). - Ensure the selected interpreter identity is mixed into the fingerprinted filename. - Add a test for the pex filename fingerprinting and that the pex can be successfully executed for python 2 and 3 constraints. ### Result A significant amount of time spent waiting after clean builds is removed, and pex tools can have their own interpreter constraints as necessary. commit 04c4ee0 Author: Eric Arellano <[email protected]> Date: Fri Feb 22 12:36:56 2019 -0700 Move debugging to proper location It's failing before the release.sh script is even called. The bootstrap command is what's failing. commit e502f58 Author: Eric Arellano <[email protected]> Date: Fri Feb 22 12:24:33 2019 -0700 Fix linux ucs4 stage being overriden to cron instead of test commit 2cd72e4 Author: Eric Arellano <[email protected]> Date: Fri Feb 22 09:47:16 2019 -0700 Add back logging to debug osx ucs4 commit c9e1650 Merge: 7da092b 4097052 Author: Eric Arellano <[email protected]> Date: Fri Feb 22 09:40:38 2019 -0700 Merge branch 'master' of github.com:pantsbuild/pants into py2-wheels-abi-specified commit 4097052 Author: Stu Hood <[email protected]> Date: Thu Feb 21 13:49:16 2019 -0800 Prepare 1.14.0rc3 (pantsbuild#7274) commit ea33c36 Author: Nora Howard <[email protected]> Date: Wed Feb 20 12:43:32 2019 -0700 [jvm-compile] fix typo: s/direcotry/directory/ (pantsbuild#7265) Fix a typo in `jvm_compile.py` commit 761849e Author: Danny McClanahan <[email protected]> Date: Wed Feb 20 11:38:39 2019 -0800 Fix nightly cron ctypes enum failure (pantsbuild#7249) ### Problem Resolves pantsbuild#7247. `ToolchainVariant('gnu')` does not in fact `== 'gnu'`. ### Solution - Use `.resolve_for_enum_variant()` instead of comparing with equality in that one failing test (I missed this in pantsbuild#7226, I fixed the instance earlier in the file though). - Raise an error when trying to use `==` on an enum to avoid this from happening again. - Note that in Python 3 it appears that `__hash__` must be explicitly implemented whenever `__eq__` is overridden, and this appears undocumented. ### Result The nightly cron job should be fixed, and enums are now a little more difficult to screw up. # Open Questions It's a little unclear why this didn't fail in CI -- either the test was cached, or some but not all travis osx images are provisioned with the correct dylib, causing a nondeterministic error, or something else? commit 0e6a144 Author: Daniel Wagner-Hall <[email protected]> Date: Wed Feb 20 04:14:23 2019 +0000 Node is Display (pantsbuild#7264) Use standard traits, rather than our own methods which happen to do the same thing. commit 904e3f3 Author: Ekaterina Tyurina <[email protected]> Date: Wed Feb 20 01:03:42 2019 +0000 Allow passing floating point numbers from rust to python (pantsbuild#7259) PR allows passing float points from Rust to Python. ``` externs::store_f64(v: f64) ``` commit 7da092b Author: Eric Arellano <[email protected]> Date: Tue Feb 19 17:03:59 2019 -0700 Fix platform default shards bootstrapping - OSX UCS2 shard no longer was setting RUN_PANTS_FROM_PEX anywhere - Linux UCS4 had its before_script entry being override by travis_image. commit 38e1cf7 Author: Eric Arellano <[email protected]> Date: Tue Feb 19 15:35:15 2019 -0700 Remove unncessary RUN_PANTS_FROM_PEX=0 Now that we don't it in the base_build_wheels_env, we don't need to set this.

Whereas for most shards we specify if they run with Py36 vs Py27 in parantheses, it is actually very important we make explicit the wheel building config, as it impacts which wheels we end up producing. commit 170e9c8 Author: Eric Arellano <[email protected]> Date: Sat Feb 16 19:10:24 2019 -0800 Install OpenSSL on OSX UCS4 shard The shard was failing when trying to build cryptography from an sdist because it could not find openssl. So, we now explicitly install it with Brew and modify the env vars to expose it. This is identical to how we install Py3 on OSX. commit e87f567 Author: Eric Arellano <[email protected]> Date: Sat Feb 16 18:14:57 2019 -0800 Fix typo in Dockerfile path The folder path is py27, not py2! commit cb50136 Author: Stu Hood <[email protected]> Date: Fri Feb 15 20:04:46 2019 -0800 Prepare 1.14.0.rc2 instead.

Fixes pantsbuild#7229, and fixes pantsbuild#5802. commit 594f91f Author: Ekaterina Tyurina <[email protected]> Date: Fri Feb 15 01:54:51 2019 +0000 Add checks if values of flags zipkin-trace-id and zipkin-parent-id are valid (pantsbuild#7242) ### Problem When pants are called with flags zipkin-trace-id and zipkin-parent-id an assertion error is raised if the values of the flag are of the wrong format. The error is not informative. ### Solution Checks of values of flags zipkin-trace-id and zipkin-parent-id are added with a better error explanation. Users of the pants are asked to use 16-character or 32-character hex string. Also, tests are added for these checks. commit bc0536c Author: Stu Hood <[email protected]> Date: Thu Feb 14 13:59:26 2019 -0800 Remove deprecated test classes (pantsbuild#7243) ### Problem `BaseTest` and the v1-aware `TaskTestBase` are long deprecated. Additionally, the `GraphTest` classes used v2 APIs that existed before `TestBase` came around. ### Solution Delete deprecated classes, and port `GraphTest` to `TestBase`. commit e4456fd Author: Danny McClanahan <[email protected]> Date: Tue Feb 12 18:09:35 2019 -0800 fix expected pytest output for pytest integration after pinning to 3.0.7 (pantsbuild#7240) ### Problem pantsbuild#7238 attempted to fix an upstream pytest issue (and therefore unbreak our CI) by pinning the default pytest version in our pytest subsystem to `pytest==3.0.7`. This worked, but broke a few of our other tests which relied on specific pytest output, and master is broken now (sorry!). I also hastily merged pantsbuild#7226, which introduced another test failure, which I have fixed. These are the only failing tests, and these all now pass locally on my laptop. ### Solution - Fix expected pytest output in pytest runner testing. ### Result I think it's still a good idea to string match pytest output unless we suddenly have to change pytest versions drastically like this again. commit e382541 Author: Danny McClanahan <[email protected]> Date: Tue Feb 12 12:54:49 2019 -0800 Canonicalize enum pattern matching for execution strategy, platform, and elsewhere (pantsbuild#7226) ### Problem In pantsbuild#7092 we added [`NailgunTask#do_for_execution_strategy_variant()`](https://github.com/cosmicexplorer/pants/blob/70977ef064305b78406a627e07f4dae3a60e4ae4/src/python/pants/backend/jvm/tasks/nailgun_task.py#L31-L43), which allowed performing more declarative execution strategy-specific logic in nailgunnable tasks. Further work with rsc will do even more funky things with our nailgunnable task logic, and while we will eventually have a unified story again for nailgun and subprocess invocations with the v2 engine (see pantsbuild#7079), for now having this check that we have performed the logic we expect all execution strategy variants is very useful. This PR puts that pattern matching logic into `enum()`: https://github.com/pantsbuild/pants/blob/84cf9a75dbf68cf7126fe8372ab9b2f48720464d/src/python/pants/util/objects.py#L173-L174, among other things. **Note:** `TypeCheckError` and other exceptions are moved up from further down in `objects.py`. ### Solution - add `resolve_for_enum_variant()` method to `enum` which does the job of the previous `do_for_execution_strategy_variant()` - make the native backend's `Platform` into an enum. - stop silently converting a `None` argument to the enum's `create()` classmethod into its`default_value`. - add `register_enum_option()` helper method to register options based on enum types. ### Result We have a low-overhead way to convert potentially-tricky conditional logic into a checked pattern matching-style interface with `enum()`, and it is easier to register enum options. commit d0432df Author: Danny McClanahan <[email protected]> Date: Tue Feb 12 12:50:59 2019 -0800 Pin pytest version to avoid induced breakage from more-itertools transitive dep (pantsbuild#7238) ### Problem A floating transitive dependency of pytest, `more-itertools`, dropped support for python 2 in its 6.0.0 release -- see pytest-dev/pytest#4770. This is currently breaking our and our users' CI: see https://travis-ci.org/pantsbuild/pants/jobs/492004734. We could pin that dep, but as mentioned in pytest-dev/pytest#4770 (comment), pinning transitive deps of pytest would impose requirement constraints on users of pytest in pants. ### Solution - Pin `pytest==3.0.7` for now. ### Result python tests should no longer be broken. commit 3d7a295 Author: Danny McClanahan <[email protected]> Date: Mon Feb 11 22:02:21 2019 -0800 add a TypedCollection type constraint to reduce boilerplate for datatype tuple fields (pantsbuild#7115) ### Problem *Resolves pantsbuild#6936.* There's been a [TODO in `pants.util.objects.Collection`](https://github.com/pantsbuild/pants/blob/c342fd3432aa0d73e402d2db7e013ecfcc76e9c8/src/python/pants/util/objects.py#L413) for a while to typecheck datatype tuple fields. pantsbuild#6936 has some thoughts on how to do this, but after realizing I could split out `TypeConstraint` into a base class and then introduce `BasicTypeConstraint` for type constraints which only act on the type, I think that ticket is invalidated as this solution is much cleaner. ### Solution - Split out logic for basic type checking (without looking at the object itself) into a `BasicTypeConstraint` class, which `Exactly` and friends inherit from. - Create the `TypedCollection` type constraint, which checks that its argument is iterable and then validates each element of the collection with a `BasicTypeConstraint` constructor argument. - Note that `TypedCollection` is a `TypeConstraint`, but not a `BasicTypeConstraint`, as it has to inspect the actual object object to determine whether each element matches the provided `BasicTypeConstraint`. - Move `pants.util.objects.Collection` into `src/python/pants/engine/objects.py`, as it is specifically for engine objects. - Use `TypedCollection` for the `dependencies` field of the datatype returned by `Collection.of()`. ### Result - `datatype` consumers and creators no longer have to have lots of boilerplate when using collections arguments, and those arguments can now be typechecked and made hashable for free! ### TODO in followup: `wrapper_type` See pantsbuild#7172. commit 1e83f37 Author: Eric Arellano <[email protected]> Date: Mon Feb 11 17:37:31 2019 -0700 Setup UCS2 vs UCS4 travis shards We must now build pantsbuild.pants with both unicode versions for Py2. So, we introduce Py2 to do this. We use Pyenv to install interpreter with the relevant encoding where necessary. See https://stackoverflow.com/questions/38928942/build-python-as-ucs-4-via-pyenv. commit a02dde1 Author: Eric Arellano <[email protected]> Date: Thu Feb 7 11:33:53 2019 -0700 Add ext_modules to BUILD entry This is going to be necessary to release Py3 with abi3. The line however results in the issue that this PR is going to aim to fix: now Python 2 will be built with abi `cp27m` or `cp27mu`, whereas earlier it was `none`. To test, try running `./pants setup-py --run="bdist_wheel --python-tag cp27 --plat-name=linux_x86_64" src/python/pants:pants-packaged` followed by `ls -l dist/pantsbuild.pants-1.14.0rc0/dist/`. Note also that ext_modules is deprecated in favor of distutils.Extension. We use this now as a temporary workaround until we add support for Extension. commit 874ce34 Author: Chris Livingston <[email protected]> Date: Mon Feb 11 13:27:50 2019 -0500 Validate and maybe prune interpreter cache run over run (pantsbuild#7225) * Purge stale interpreters from Interpreter Cache commit 5d28cf8 Author: Daniel Wagner-Hall <[email protected]> Date: Fri Feb 8 14:58:23 2019 +0000 Prep for 1.15.0.dev0 (pantsbuild#7230) commit 84cf9a7 Author: Danny McClanahan <[email protected]> Date: Wed Feb 6 13:56:35 2019 -0800 deprecate implicit usage of binary_mode=True and mode='wb' in dirutil methods (pantsbuild#7120) ### Problem *Resolves pantsbuild#6543. See also [the python 3 migration project](https://github.com/pantsbuild/pants/projects/10).* There has been [a TODO](https://github.com/pantsbuild/pants/blob/6fcd7f7d0f8787910cfac01ec2895cdbd5cee66f/src/python/pants/util/dirutil.py#L109) pointing to pantsbuild#6543 to deprecate the `binary_mode` argument to `pants.util.dirutil.safe_file_dump()`, which wasn't canonicalized with a `deprecated_conditional`. This is because `binary_mode` doesn't quite make sense the way it does with file read methods `read_file()` and `maybe_read_file()`, because a file can be appended to as well as truncated (as opposed to reads). Separately, defaulting `binary_mode=True` for file read methods means more explicit conversions to unicode in a python 3 world, ### Solution - Deprecate the `binary_mode` argument to `safe_file_dump()`, as well as not explicitly specifying the `mode` argument. - `safe_file_dump()` now also defaults `payload=''`. - Also deprecate not specifying the `mode='wb'` argument in `safe_file_dump()`. - Deprecate not explicitly specifying the `binary_mode` argument in `{maybe_,}read_file()` and `temporary_file()` so that it can be given a default of unicode when pants finishes [migrating to python 3](https://github.com/pantsbuild/pants/projects/10) -- see pantsbuild#7121. - Update usages of `safe_file_dump()` across the repo. ### Result Pants plugins will see a deprecation warning if they fail to explicitly specify the `binary_mode` for file read methods in preparation for switching the default to unicode for [the python 3 switchover](https://github.com/pantsbuild/pants/projects/10). Several ambiguities in the `safe_file_dump()` method are alleviated. pantsbuild#7121 covers the eventual switchover to a default of `binary_mode=False` after the python 3 migration completes. commit 224c2a0 Author: Borja Lorente <[email protected]> Date: Wed Feb 6 19:21:10 2019 +0000 Make Resettable lazy again (pantsbuild#7222) ### Problem In the context of pantsbuild#6817, there is a logging issue that manifests when the daemon forks. In particular, in `fork_context`, both the daemon and the client reset some services that implement `Resettable`. Some of those services log at startup, when the client hasn't had time to reconfigure its logging to stderr, and therefore all these startup logs are intermingled in the `pantsd.log` file. ### Solution If we make `Resettable` lazy again, since we are ensured to only enter `fork_context` under a lock, the logging can only happen when the client has had time to configure its loggers. ### Result `Resettable` is now lazy. `Resettable::get()` is now implemented in terms of `Resettable::with`. commit f281642 Author: Danny McClanahan <[email protected]> Date: Wed Feb 6 10:26:07 2019 -0800 fix _raise_deferred_exc() (pantsbuild#7008) ### Problem The `_raise_deferred_exc(self)` method in `daemon_pants_runner.py` hasn't ever been tested. As a result, it causes an easily fixable error: the issue can be easily reproduced if you register an option twice in the same task and then run with pantsd enabled (you get the wrong exception, because `exc_type` isn't needed to construct the exception again, that's what `exc_value` is for). ### Solution - Appropriately destructure `sys.exc_info()` (if that was what was used to populate `self._deferred_exception`) and re-raise the exception with its original traceback. ### Result This error is fixed, but not yet tested -- see pantsbuild#7220. commit f0a1a9f Author: Stu Hood <[email protected]> Date: Wed Feb 6 07:17:10 2019 -0800 Prepare 1.14.0rc1 (pantsbuild#7221) commit b6f045d Author: Daniel Wagner-Hall <[email protected]> Date: Wed Feb 6 10:47:30 2019 +0000 Resolve all platforms from all python targets (pantsbuild#7156) Don't just use the default configured targets. This means that _all_ transitive 3rdparty python will need to be resolvable in _all_ platforms in any target in the graph. This is not ideal (we really want to be doing per-root resolves), but because we currently do one global resolve, this is a decent fit. commit b08c1fd Author: Ekaterina Tyurina <[email protected]> Date: Wed Feb 6 10:40:35 2019 +0000 Add flag reporting-zipkin-sample-rate (pantsbuild#7211) ### Problem In the current implementation, every time the pants command is run with zipkin tracing turned on all the zipkin traces will be collected. It is not very convenient when the number of runs is very big. ### Solution Possibility to set the sample rate will allow us to have the number of traces that fits the constraints of Zipkin server. ### Result A flag `reporting-zipkin-sample-rate` was added that sets the sample rate at which to sample Zipkin traces. If flags `reporting-zipkin-trace-id` and `reporting-zipkin-parent-id` are set the sample rate will always be 100.0 (no matter what is set in `reporting-zipkin-sample-rate` flag). commit 95638d3 Author: Stu Hood <[email protected]> Date: Tue Feb 5 16:19:17 2019 -0800 Only lint the direct sources of a linted target. (pantsbuild#7219) ### Problem The thrift linter currently redundantly lints the transitive dependencies of each target, leading to repetitive errors, and larger tool invokes than necessary. ### Solution Lint only the directly owned sources of a target, and expand unit tests. commit 121f98c Author: Stu Hood <[email protected]> Date: Tue Feb 5 16:05:11 2019 -0800 Do not render the coursier workunit unless it will run. (pantsbuild#7218) ### Problem Currently the `bootstrap-coursier` workunit is rendered repeatedly, although it only actually runs once. ### Solution Only render the workunit if it will run. commit b2f5a49 Author: Marcin Podolski <[email protected]> Date: Wed Feb 6 00:17:09 2019 +0100 documentation for grpcio (pantsbuild#7155) ### Problem Documentation for grpcio generation tool commit f73f112 Author: Daniel Wagner-Hall <[email protected]> Date: Tue Feb 5 15:33:43 2019 +0000 Skip flaky test (pantsbuild#7209) Relates to pantsbuild#7199 commit f0bb0da Author: Stu Hood <[email protected]> Date: Mon Feb 4 20:51:34 2019 -0800 Only run master-dependent commithooks on master (pantsbuild#7214) ### Problem See pantsbuild#7213: some commit hooks are only valid in a context where master is present (and should otherwise be skipped). ### Solution Move more hooks that reference `master` under the check for the presence of `master`. ### Result Fixes pantsbuild#7213, and unblocks further iteration on the `1.14.x` stable branch.

Followup to #7275 following discussion that the target filter was being applied to tasks that do not support it (e.g. tasks that don't access targets via
get_targets())This adds a class property to
Taskthat allows subclasses to effectively opt-in to the new behavior - and sets that flag toTrueforfmtandlinttasks.
