[Swift CI] Build Failure: 2. Swift Source Compatibility Suite (master) #1014

Vedant, this appears to be a result of your changes.

I’ve opened https://github.com/apple/swift/pull/13709 to revert the later clean-up change which appears to be required before it will be possible to revert the change below.

This is a bit surprising, since I wouldn't expect this suite of tests to stress the code coverage logic.

How were you able to determine that the #13597 caused the break? I'm having a hard time understanding what the logs mean. For example, I see this failure, but I'm not sure how my change relates to it:

Can I reproduce the issue with `build-script -t`?

edit: lib/IDE/CodeCompletion.cpp

This is a bit surprising, since I wouldn't expect this suite of tests to stress the code coverage logic.

How were you able to determine that the #13597 caused the break?

I’m seeing this in the failing builds:

Assertion failed: (std::all_of(Mappings.begin(), Mappings.end(), [](const SILCoverageMap &M) { return M.hasSymtabEntry(); }) && "Missing symtab entry for coverage mapping"), function emitCoverageMapping, file /Users/buildnode/jenkins/workspace-private/swift-master-source-compat-suite/swift/lib/IRGen/GenCoverage.cpp, line 53.

I'm having a hard time understanding what the logs mean. For example, I see this failure, but I'm not sure how my change relates to it:

It’s non-obvious, but the easiest thing to do is download the build artifacts via a couple clicks from https://ci.swift.org/job/swift-master-source-compat-suite/1014/, and then look at the logs named FAIL_*.

You should be able to reproduce by building and then following the instructions here to run a single project build: https://github.com/apple/swift-source-compat-suite/blob/master/README.md

[code-complete] Don't suggest trailing closure for autoclosure

edit: test/IDE/complete_trailing_closure.swift
edit: lib/IDE/CodeCompletion.cpp

This is a bit surprising, since I wouldn't expect this suite of tests to stress the code coverage logic.

How were you able to determine that the #13597 caused the break?

I’m seeing this in the failing builds:

Assertion failed: (std::all_of(Mappings.begin(), Mappings.end(), [](const SILCoverageMap &M) { return M.hasSymtabEntry(); }) && "Missing symtab entry for coverage mapping"), function emitCoverageMapping, file /Users/buildnode/jenkins/workspace-private/swift-master-source-compat-suite/swift/lib/IRGen/GenCoverage.cpp, line 53.

I added this assert as a debugging tool, with plans on making it a defensive measure. I.e, we'd use the check to avoid emitting broken coverage mapping data. Instead of reverting, it might be easier to finish that up. Wdyt?

I'm having a hard time understanding what the logs mean. For example, I see this failure, but I'm not sure how my change relates to it:

It’s non-obvious, but the easiest thing to do is download the build artifacts via a couple clicks from https://ci.swift.org/job/swift-master-source-compat-suite/1014/, and then look at the logs named FAIL_*.

Thanks, I see the failures now.

Is that something you can do quickly?

It’s blocking PR testing for source compatibility, which means we get no coverage for people that want to run those tests until this is fixed or reverted.

[code-complete] Don't suggest trailing closure for autoclosure

edit: test/IDE/complete_trailing_closure.swift
edit: lib/IDE/CodeCompletion.cpp

This is a bit surprising, since I wouldn't expect this suite of tests to stress the code coverage logic.

How were you able to determine that the #13597 caused the break?

I’m seeing this in the failing builds:

Assertion failed: (std::all_of(Mappings.begin(), Mappings.end(), [](const SILCoverageMap &M) { return M.hasSymtabEntry(); }) && "Missing symtab entry for coverage mapping"), function emitCoverageMapping, file /Users/buildnode/jenkins/workspace-private/swift-master-source-compat-suite/swift/lib/IRGen/GenCoverage.cpp, line 53.

I added this assert as a debugging tool, with plans on making it a defensive measure. I.e, we'd use the check to avoid emitting broken coverage mapping data. Instead of reverting, it might be easier to finish that up. Wdyt?

Is that something you can do quickly?

I think so, I should have it done tonight. If it's looking unlikely, I can finish up the revert of #13597. Is that ok?

To follow up on this thread, I reverted #13597 (the profiling refactor) because I couldn't get a clean run of the source compat suite.

It looks like there's an issue unrelated to #13597 causing a few failures: https://ci.swift.org/view/Source%20Compatibility/job/swift-master-source-compat-suite/1017/

[code-complete] Don't suggest trailing closure for autoclosure

edit: test/IDE/complete_trailing_closure.swift
edit: lib/IDE/CodeCompletion.cpp

This is a bit surprising, since I wouldn't expect this suite of tests to stress the code coverage logic.

How were you able to determine that the #13597 caused the break?

I’m seeing this in the failing builds:

Assertion failed: (std::all_of(Mappings.begin(), Mappings.end(), [](const SILCoverageMap &M) { return M.hasSymtabEntry(); }) && "Missing symtab entry for coverage mapping"), function emitCoverageMapping, file /Users/buildnode/jenkins/workspace-private/swift-master-source-compat-suite/swift/lib/IRGen/GenCoverage.cpp, line 53.

I added this assert as a debugging tool, with plans on making it a defensive measure. I.e, we'd use the check to avoid emitting broken coverage mapping data. Instead of reverting, it might be easier to finish that up. Wdyt?

Is that something you can do quickly?

I think so, I should have it done tonight. If it's looking unlikely, I can finish up the revert of #13597. Is that ok?

vedant

Why don’t you just temporarily disable the assertion?

[code-complete] Don't suggest trailing closure for autoclosure

edit: test/IDE/complete_trailing_closure.swift
edit: lib/IDE/CodeCompletion.cpp

To follow up on this thread, I reverted #13597 (the profiling refactor) because I couldn't get a clean run of the source compat suite.

It looks like there's an issue unrelated to #13597 causing a few failures: https://ci.swift.org/view/Source%20Compatibility/job/swift-master-source-compat-suite/1017/
ld: warning: unable to create link snapshot directory: /tmp/AsyncNinja-2018-00-04-030527.ld-snapshot
ld: snapshot not created in 'l_protocol_conformances' from /Users/buildnode/jenkins/workspace-private/swift-master-source-compat-suite/project_cache/AsyncNinja/build/Build/Intermediates.noindex/AsyncNinja.build/Release-iphoneos/AsyncNinja.build/Objects-normal/arm64/iOS.o for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is probably mine. Trying to reproduce now.

[code-complete] Don't suggest trailing closure for autoclosure

edit: test/IDE/complete_trailing_closure.swift
edit: lib/IDE/CodeCompletion.cpp

This is a bit surprising, since I wouldn't expect this suite of tests to stress the code coverage logic.

How were you able to determine that the #13597 caused the break?

I’m seeing this in the failing builds:

Assertion failed: (std::all_of(Mappings.begin(), Mappings.end(), [](const SILCoverageMap &M) { return M.hasSymtabEntry(); }) && "Missing symtab entry for coverage mapping"), function emitCoverageMapping, file /Users/buildnode/jenkins/workspace-private/swift-master-source-compat-suite/swift/lib/IRGen/GenCoverage.cpp, line 53.

I added this assert as a debugging tool, with plans on making it a defensive measure. I.e, we'd use the check to avoid emitting broken coverage mapping data. Instead of reverting, it might be easier to finish that up. Wdyt?

Is that something you can do quickly?

I think so, I should have it done tonight. If it's looking unlikely, I can finish up the revert of #13597. Is that ok?

vedant

Why don’t you just temporarily disable the assertion?

I thought it'd be simpler to finish up the planned work. I've got the patch ready: https://github.com/apple/swift/pull/13711. If it'd be better to have a smaller change, I'm open to disable the assert.

It’s blocking PR testing for source compatibility, which means we get no coverage for people that want to run those tests until this is fixed or reverted.

I'm having a hard time understanding what the logs mean. For example, I see this failure, but I'm not sure how my change relates to it:

It’s non-obvious, but the easiest thing to do is download the build artifacts via a couple clicks from https://ci.swift.org/job/swift-master-source-compat-suite/1014/, and then look at the logs named FAIL_*.

Thanks, I see the failures now.

You should be able to reproduce by building and then following the instructions here to run a single project build: https://github.com/apple/swift-source-compat-suite/blob/master/README.md
