Description Robert Scheck 2004-08-19 00:29:26 UTC
Description of problem:
If I try rebuild php, some php tests freeze my system completely 
down at rebuilding time. The onliest, I can see is load > 7, then 
ca. 25-30 defunct processes, load > 15 - after that nothing happens 
for the next 15 minutes...okay then I did a hard reset :-(

That system is a Intel Pentium 1 GHz machine. At a AMD Athlon 2,4 
GHz I get a load of ~ 25 the system hangs up (soft freeze?) for ca. 
2 minutes, then the building goes on. I didn't try to reproduce that 
problem at other platforms, yet.

Version-Release number of selected component (if applicable):
(all Rawhide)

How reproducible:
Everytime, see below.

Steps to Reproduce:
1. rpmbuild --rebuild php-4.3.8-4.src.rpm
2. Get the freeze (or hangup) at php tests
Actual results:
After a change like the following, the rebuild runs fine without
any problem (behaviour at php < 4.3.7-4):

Expected results:
Rebuild without system hangup or freeze at running php tests.

Comment 1 Joe Orton 2004-08-19 09:41:04 UTC
Which of the bugs is causing the system load - what's the last test
result printed before the issues?

Comment 2 Robert Scheck 2004-08-19 12:41:50 UTC
Oh sorry, I forgot it. The last 5 lines before the freeze:

--- snipp ---
PASS is_*() and file_exists() return values are boolean. [ext/standard/tests/file/003.phpt]
PASS Bug #12556 (fgetcsv() ignores lengths when quotes not closed) [ext/standard/tests/file/bug12556.phpt]
PASS Bug #20424 (stream_get_meta_data crashes on a normal file stream) [ext/standard/tests/file/bug20424.phpt]
PASS Bug #22362: combinations of fseek() and fwrite() produce unexpected results. [ext/standard/tests/file/bug22362.phpt]
PASS Bug #22382 (fgetcsv() does not handle escaped quotes correctly) [ext/standard/tests/file/bug22382.phpt]
--- snapp ---

So I guess, the hangup/freeze is caused by:

-rw-r--r--    1 root     root          642 Jul 15  2003 bug22414.phpt

which would be the next test (if I am right)...

Comment 3 Joe Orton 2004-08-19 12:45:15 UTC
Ah, that's probably right, that test is usually a problem.  It invokes
/usr/bin/php with lots of recursion; I'll disable it again.
