Re: [cdt-dev] Improved reliability of Index tests
|
Hi Marc-André
Please see https://git.eclipse.org/r/#/c/24080/ again. It is now rebased
to master. The new build even got +1 from hudson.
I actually do not exactly know at what point the
workspace.build(IncrementalProjectBuilder.FULL_BUILD) method helps the
cdt index tests. It seems to refresh resources and hence get rid of
outdated cache stuff. This then makes the index more up to date than
without rebuilding.

Hi Lukas,
Can you explain what is the purpose of the build? Also, if you rebase
your patch, I made changed to CDescriptorTests and codan so that they
run more reliably.

Hello Everyone
I created a small patch ( https://git.eclipse.org/r/24080 ) that
improves the reliability of index tests.
When running the 65 IndexBugsTests 50 times (total 3250 test runs)
from a test suite, I got 90 to 100 random test failures.
After my adaptions, failures are reduced to 0-5 failures (sadly not to
0). Meaning a failure reduction of ~95%. When running all core tests,
I never saw an index test fail (in 10+ runs). Those CDescriptorTests
do still fail (I did not touch these).
The adaptions do not have any impact on run-time (+/- 3%). And I was
able to remove the very ugly part that called Thread.sleep() in a loop.
The better result is achieved by having two additional calls to
workspace.build(IncrementalProjectBuilder.FULL_BUILD) which basically
is similar to a "clean..." call from the "Project" eclipse ui-menu.
I hope that some of you guys can try the patch and check if it does
not have any negative effects somewhere (I only checked the cdt-core
and codan tests).
Cheers
Lukas
PS: I will most likely not be active in CDT development in the near
future since I'm leaving HSR and moving on to IBM.
