Bug ID: 22488
Summary: abipkgdiff sometimes compares with wrong elf file when
multiple elf files with same name are available in a
package
Product: libabigail
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: default
Assignee: dodji at redhat dot com
Reporter: sinny at redhat dot com
CC: libabigail at sourceware dot org
Target Milestone: ---
It looks like abipkgdiff tool doesn't take into account relative elf file path
while doing ABI comparison on a binary file available in two packages to be
compared. Due to this, abipkgdiff may show false positive ABI changes if a
package has multiple binaries with same name.
For example:
We have seen false positive result in task-abicheck run on php-odbc sub-package
from php -
https://taskotron.fedoraproject.org/artifacts/all/3dd146e8-cf54-11e7-a1d7-525400817a8f/task_output/php-7.1.12-1.fc27.log
* Incompatible ABI changes between php-odbc-7.1.11-1.fc27.i686.rpm and
php-odbc-7.1.12-1.fc27.i686.rpm. ABI comparison took 0.56 second(s). Please
review them.

================ end of changes of 'odbc.so'===============
When we look inside one of php-odbc sub-package(
https://kojipkgs.fedoraproject.org//packages/php/7.1.11/1.fc27/i686/php-odbc-7.1.11-1.fc27.i686.rpm
), it contains twice odbc.so library in same package.
$ ls php-odbc-7.1.11-1/usr/lib/php/modules/
odbc.so pdo_odbc.so
$ ls usr/lib/php-zts/modules/
odbc.so pdo_odbc.so
