Support execution constraints per exec group #13110

quval · 2021-02-25T20:40:39Z

When computing exec properties from the execution platform for an action, take into account only the properties that are relevant to the action's exec groups. In particular, allow setting exec properties for arbitrary exec groups on platforms. Previously, any such properties were rejected.

With this change, the following becomes possible:

cc_test(
    name = "my_test",
    ...,
    exec_properties = {
        "test.key": "value",
    },
)

This will apply {"key": "value"} for the test-runner action only (i.e., compilation and linkage won't be affected). The following also becomes possible:

platform(
    name = "test_platform",
    constraint_values = [":test_constraint"],
    exec_properties = {
        "test.key": "value",
    },
)

cc_test(
    name = "my_test",
    ...,
    exec_compatible_with = [":test_constraint"],
)

This achieves the same in a more succinct way.

I am rolling forward the test exec change separately (#13119) so it can be separated from this. Once that is in place, can you rebase and update the commits to make the CLA bot happy?

quval · 2021-02-26T14:17:08Z

Sure, will do (in fact, I believe this PR only includes those changes, but I originally based it on #12719).

Previously, exec groups were rejected on platforms. This change allows setting arbitrary exec groups on platforms, and applying only the relevant ones to actions after platform resolution. Also fixes a bug where the default execution platform for the "test" execution group did not take into account execution constraints set on targets.

…r specific groups take precedence.

@katre: rebased and double-checked everything's in order. Thanks!

katre · 2021-03-03T21:30:34Z

Thanks! I've taken a quick look at this and it seems okay, but I want to think about it some more. One thing that would really help would be if you could add a test case to https://cs.opensource.google/bazel/bazel/+/master:src/test/shell/bazel/toolchain_test.sh: this will a) test the code, and b) show how it's intended to be used.

It would also be useful to add tests to https://cs.opensource.google/bazel/bazel/+/master:src/test/java/com/google/devtools/build/lib/analysis/StarlarkExecGroupTest.java

quval · 2021-03-03T21:38:25Z

Great, will do. I've been wondering where would tests actually go. Thank you!

quval · 2021-03-03T23:24:01Z

Added a couple of test cases. I think that just about covers it, but do let me know if you think any more could be helpful.

katre

Looks good, just a few comments and then this will be ready to merge. Thanks for working with me to get this in shape!

I didn't know this syntax existed. I see the benefits, but it's very different than all the other tests, so can you please change this back to the previous style, and use the same style in your new tests? I think consistency is better in this case.

Done. I couldn't figure out why, but one of the tests failed with that style (and I missed the test case with expected failure). I ended up removing it, as there is a positive test anyway.

Wow, I hate Map> so much, but I see this predates your change so leave it. I will probably send a followup shortly to change this to a Table.

Acknowledged. I didn't know about Table (never wrote Java at Google). I would be happy to fix this - please let me know if you'd like me to do this as part of this PR - but you probably have more context.

quval · 2021-03-04T16:23:06Z

Thanks for the review! It's been a while since I made this change, and initially I intended it as a sketch - glad it can be merged.

katre · 2021-03-05T17:34:09Z

I'm merging this today. Thanks for your patience!

The internal reviewer did have one request: can you send a separate PR to update the docs for exec groups (at https://github.com/bazelbuild/bazel/blob/master/site/docs/exec-groups.md) to mention the new functionality?

See #12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.

See bazelbuild#12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.

(Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.

(Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.

Does this only work for test actions of native rules? I'm noticing that rust_test rules from bazelbuild/rules_rust do not get test.foo attributes set on their executions, while native rules like sh_test seem to work correctly. Since test rules just return an executable, I'm not sure how a rule author would go about adding the test exec group to the test runner action.

katre · 2021-09-13T14:23:48Z

Hmm, all test rules should get the "test" exec group added, but I'm not sure I've ever tested that with Starlark rules. Can you open a separate issue and ping me?

quval · 2021-09-13T15:41:50Z

@katre @djmarcin This isn't instead of a new issue, and it's probably better if you take a look, but I've actually taken a look yesterday and thought I might share my findings - looks like this line is missing here (or possibly better, here, to prevent breaking those who have already added a test exec group manually). I started preparing a PR, but for some reason couldn't get the tests to pass even though a manual run with the patched Bazel did work correctly.

katre · 2021-09-13T15:46:15Z

This is a pull request, so I'd prefer to have an issue I can track and attach pull requests to. Unless there's another issue you think already fits this?

quval · 2021-09-13T16:07:15Z

No, I was just sharing my thoughts in the meantime until @djmarcin opens an issue.

See #12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Fabian Meumertzheim, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Noa Resare, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, Xavier Bonaventura, Yannic Bonenberger, Yuval, Yuval Kaplan, bjacklyn, bromano, wisechengyi.

See #12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Fabian Meumertzheim, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Noa Resare, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, Xavier Bonaventura, Yannic Bonenberger, Yuval, Yuval Kaplan, bjacklyn, bromano, wisechengyi.

See bazelbuild#12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Fabian Meumertzheim, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Noa Resare, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, Xavier Bonaventura, Yannic Bonenberger, Yuval, Yuval Kaplan, bjacklyn, bromano, wisechengyi.

(#16450) (#16459) Incompatible changes: - GrpcRemoteDownloader only includes relevant headers instead of sending all credentials. Closes #16439. Important changes: - Multiplex persistent workers can now use the JSON protocol. - enforce config_setting visibility. See #12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bjacklyn, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Fabian Meumertzheim, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, Lauri Peltonen, Noa Resare, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.

Closes #16439. Important changes: - Multiplex persistent workers can now use the JSON protocol. - enforce config_setting visibility. See #12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bjacklyn, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Fabian Meumertzheim, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, kshyanashree, Lauri Peltonen, Noa Resare, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.

Closes bazelbuild#16439. Important changes: - Multiplex persistent workers can now use the JSON protocol. - enforce config_setting visibility. See bazelbuild#12932 for details. - The minimum Android build tools version for the Android rules is now 30.0.0 - Updates worker protocol with cancellation fields, and adds experimental_worker_cancellation flag to control cancellation. - If all strategies of one branch (the local or remote execution branch) of the `dynamic` strategy fail to even accept (via the response they give from `canExec`) the action, `dynamic` will now try to see if the other branch can accept it. (Trying to run it and it failing will still cause a failure if it was the first result, this is about strategies claiming they can't even try the action) This release contains contributions from many people at Google, as well as Alex Eagle, Austin Schuh, Benjamin Peterson, bjacklyn, bromano, Christopher Peterson Sauer, Christopher Sauer, Cristian Hancila, Daniel Wagner-Hall, Denys Kurylenko, Ed Schouten, Fabian Meumertzheim, Finn Ball, George Gensure, Greg Estren, Johannes Abt, Keith Smiley, Kevin Hogeland, kshyanashree, Lauri Peltonen, Noa Resare, Philipp Schrader, Ryan Beasley, Thi Doan, ThomasCJY, Timothy Klim, Trustin Lee, Ulf Adams, Vaidas Pilkauskas, Vertexwahn, wisechengyi, Xavier Bonaventura, Yannic Bonenberger, Yuval Kaplan, Yuval.
