Summary:
Added a python script to parse combined stdout/stderr of legocastle
steps. Previously we just matched words like 'Failure', which didn't work since
even our test names matched that pattern.
I went through all the legocastle steps to come up with strict failure regexes
for the common failure cases. There is also some more complex logic to present
gtest failures, since the test name and failure message are not on the same
line.
There will definitely be error cases that don't match any of these patterns, so
we can iterate on it over time.
Test Plan:
no end-to-end test. I ran the legocastle steps locally and piped to
my script, then verified output, e.g.,
$ set -o pipefail && TEST_TMPDIR=/dev/shm/rocksdb COMPILE_WITH_ASAN=1 OPT=-g make J=1 asan_check |& /usr/facebook/ops/scripts/asan_symbolize.py -d |& python build_tools/error_filter.py asan
