#2086: Fix test openFile008(ghci) by changing testlib.py to apply cmd_prefix
also
for way ghci
----------------------------+-----------------------------------------------
Reporter: thorkilnaur | Owner:
Type: bug | Status: new
Priority: normal | Component: Test Suite
Version: 6.9 | Severity: normal
Keywords: | Testcase: openFile008
Architecture: Unknown | Os: MacOS X
----------------------------+-----------------------------------------------
The test openFile008(ghci) currently fails on PPC Mac OS X 10.4 as
follows:
{{{
openFile008: openFile008_testdir/file247: openFile: resource exhausted
(Too many open files)
}}}
openFile008 opens 1000 files. And since
{{{
$ ulimit -n
256
$
}}}
on the machine where this happens, we get the error. To be sure, in
{{{testsuite/tests/ghc-regress/lib/IO/all.T}}} we find that this
eventuality has been prepared for:
{{{
test('openFile008', cmd_prefix('ulimit -n 1024; '), compile_and_run, [''])
}}}
But the testsuite {{{driver/testlib.py}}} does not apply the cmd_prefix
for way ghci. As a result, openFile008 succeeds for other ways, but not
for the ghci way.
The attached patch changes {{{driver/testlib.py}}} to apply the cmd_prefix
also for way ghci, which is one possible solution to this problem. I have
verified that other tests that use cmd_prefix have not been affected by
this change.
Best regards
