[lldb-dev] [Bug 48806] New: TestProcessAttach.py fails and hangs on Windows
https://bugs.llvm.org/show_bug.cgi?id=48806 Bug ID: 48806 Summary: TestProcessAttach.py fails and hangs on Windows Product: lldb Version: unspecified Hardware: PC OS: Windows NT Status: NEW Severity: enhancement Priority: P Component: All Bugs Assignee: lldb-dev@lists.llvm.org Reporter: sti...@microsoft.com CC: jdevliegh...@apple.com, llvm-b...@lists.llvm.org This test occasionally fails on Windows by failing to attach to the process. This causes the test to time out and the test suite to fail. On the buildbot, this causes cascading failures because future builds will fail to clean the files that are still in use by the hanging process. -- You are receiving this mail because: You are the assignee for the bug.___ lldb-dev mailing list lldb-dev@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
[lldb-dev] lldb/test/API/commands/help/TestHelp.py not running just-built lldb
On Linux (Ubuntu) + cmake + ninja, it seems this test isn't testing the checked-out lldb, but instead running the system (or user-dir, in my case) installed lldb (see examples at the end of this email) If I remove the user-dir installed lldb then the test fails differently - complaining that it can't find the lldb python bindings, it seems. So it's not even falling back to the just-built lldb, by the looks of it. Any ideas? Anyone else come across this? Should something in the testing be setting PYTHONPATH to include (preferentially/early) the just-built python lldb package? - Dave $ ./bin/llvm-lit -v tools/lldb/test/API/commands/help/TestHelp.py -- Testing: 1 tests, 1 workers -- FAIL: lldb-api :: commands/help/TestHelp.py (1 of 1) TEST 'lldb-api :: commands/help/TestHelp.py' FAILED Script: -- /usr/bin/python3 /usr/local/google/home/blaikie/dev/llvm/src/lldb/test/API/dotest.py -u CXXFLAGS -u CFLAGS --env ARCHIVER=/usr/bin/ar --env OBJCOPY=/usr/bin/objcopy --env LLVM_LIBS_DIR=/usr/local/google/home/blaikie/dev/llvm/build/default/./lib --arch x86_64 --build-dir /usr/local/google/home/blaikie/dev/llvm/build/default/lldb-test-build.noindex --lldb-module-cache-dir /usr/local/google/home/blaikie/dev/llvm/build/default/lldb-test-build.noindex/module-cache-lldb/lldb-api --clang-module-cache-dir /usr/local/google/home/blaikie/dev/llvm/build/default/lldb-test-build.noindex/module-cache-clang/lldb-api --executable /usr/local/google/home/blaikie/dev/llvm/build/default/./bin/lldb --compiler /usr/local/google/home/blaikie/dev/llvm/build/default/./bin/clang --dsymutil /usr/local/google/home/blaikie/dev/llvm/build/default/./bin/dsymutil --filecheck /usr/local/google/home/blaikie/dev/llvm/build/default/./bin/FileCheck --yaml2obj /usr/local/google/home/blaikie/dev/llvm/build/default/./bin/yaml2obj --lldb-libs-dir /usr/local/google/home/blaikie/dev/llvm/build/default/./lib /usr/local/google/home/blaikie/dev/llvm/src/lldb/test/API/commands/help -p TestHelp.py -- Exit Code: -11 Command Output (stdout): -- lldb version 12.0.0 (g...@github.com:llvm/llvm-project.git revision d49974f9c98ebce5a679eced9f27add138b881fa) clang revision d49974f9c98ebce5a679eced9f27add138b881fa llvm revision d49974f9c98ebce5a679eced9f27add138b881fa -- Command Output (stderr): -- Fatal Python error: Segmentation fault Current thread 0x7fe870b7d740 (most recent call first): File "/usr/local/google/home/blaikie/install/lib/python3/dist-packages/lldb/__init__.py", line 3098 in HandleCommand File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/packages/Python/lldbsuite/test/lldbtest.py", line 2146 in runCmd File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/test/API/commands/help/TestHelp.py", line 62 in test_help_memory_read_should_not_crash_lldb File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/packages/Python/lldbsuite/test/decorators.py", line 345 in wrapper File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/case.py", line 413 in runMethod File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/case.py", line 383 in run File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/case.py", line 458 in __call__ File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/suite.py", line 117 in _wrapped_run File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/suite.py", line 115 in _wrapped_run File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/suite.py", line 85 in run File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/suite.py", line 66 in __call__ File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/third_party/Python/module/unittest2/unittest2/runner.py", line 165 in run File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/packages/Python/lldbsuite/test/dotest.py", line 1008 in run_suite File "/usr/local/google/home/blaikie/dev/llvm/src/lldb/test/API/dotest.py", line 7 in -- Failed Tests (1): lldb-api :: commands/help/TestHelp.py Testing Time: 5.03s Failed: 1 $ ./bin/llvm-lit -v tools/lldb/test/API/commands/help/TestHelp.py -- Testing: 1 tests, 1 workers -- FAIL: lldb-api :: commands/help/TestHelp.py (1 of 1) TEST 'lldb-api :: commands/help/TestHelp.py' FAILED Script: -- /usr/bin/python3 /usr/local/google/home/blaikie/dev/llvm/src/lldb/test/API/dotest.py -u CXXFLAGS -u CFLAGS --env ARCHIVER=/usr/bin/ar --env OBJCOPY=/usr/bin/objcopy --env LLVM_LIBS_DIR=/usr/local/google/home/blaikie/dev/llvm/build/default/./lib --arch x86_64 --build-dir /usr/local/google/home/blaikie/dev/llvm/build/default/lldb-t
Re: [lldb-dev] lldb/test/API/commands/help/TestHelp.py not running just-built lldb
Jonas helped me out here (Thanks!)
Seems I was setting LD_LIBRARY_PATH for, so far as I recall, good reasons
(I have some things installed locally in $HOME/install and I thought
somewhere in the mists of time the executables ($HOME/install/bin) didn't
naturally find some shared libraries in $HOME/install/lib{,64}) but it was
definitely messing up the lldb test execution - so for now I've unset
LD_LIBRARY_PATH and I'll leave it that way/see if I rediscover what
motivated me to set it in the first place - if that comes up I'll have
something more concrete to discuss. But for now I'm unblocked/not hitting
this issue anymore.
Thanks again,
- Dave
