Description Jan Kratochvil 2007-08-03 13:25:17 EDT
Description of problem:
During the RHEL4.5->RHEL4.6 build the verification (rpmdiff) failed as the
generated strace64.debug is empty.

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

How reproducible:
Not tried.

Steps to Reproduce:
1. Build strace-4.5.16-1.el4.ppc64 in Brew.

Actual results:
-rwxr-xr-x  1 jkratoch jkratoch 301600 Aug  3 18:43
-rwxr-xr-x  1 jkratoch jkratoch   2640 Aug  3 18:43

(strace.debug correct, strace64.debug stripped)

Expected results:
-rwxr-xr-x  1 jkratoch jkratoch   2640 Aug  3 18:55
-rwxr-xr-x  1 jkratoch jkratoch 294216 Aug  3 18:55

(strace.debug stripped, strace64.debug unstripped)

Well, it is also broken but it does not hurt.
The correct way is to produce both the two .debug files unstripped.
ppc64 platform uses strace.ppc and strace64.ppc64.
The package strace.ppc64 is never used.

Additional info:
The problem is line:
ln %{buildroot}%{_bindir}/strace %{buildroot}%{_bindir}/strace64
/usr/lib/rpm/find-debuginfo.sh randomly chooses the first file and the second
one is already stripped so even its .debug file is empty/stripped.
Suggesting `ln' -> `cp -p'.

Regression on RHEL-4.5.
Problem is in debuginfo; so has no customer impact.
Workaround is trivial.
Tested automatically as part of errata process.

Recommend filling a separate bug against rpm, as I'm pretty sure this explains
why a few other programs also end up with empty debug info.
Comment 3 RHEL Product and Program Management 2007-08-03 13:45:24 EDT
This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.

Original debuginfo size:
-rwxr-xr-x  1 apache apache 263553 Aug  3 17:35
Proposed debuginfo size:

Comment 8 Jan Kratochvil 2007-08-08 09:45:46 EDT
Problem fixed in Rawhide rpm-build by the new Roland's find-debuginfo.sh,
reported for RHEL in the Bug 251333.
