Description Miroslav Vadkerti 2016-04-18 15:24:32 UTC
Description of problem:

This package is showing ABI changes which need your attention. Note that this package is on ABI compatibility list [1] in level 2. The ABI changes were tested using libabigail - abipkgdiff [2], only for subpackage:

    libtevent

See

    http://gov-cert.brq.redhat.com/abidiff/results/level2_72vs70/72vs70_libtevent-0.9.18-6.el7_vs_libtevent-0.9.25-1.el7_libtevent.txt

for detailed results from the scan. Note that the results are merged for all architectures, thus there can be some duplicity.

To reproduce the issue run the abipkgdiff on the reported package libtevent:

    $ abipkgdiff --d1 OLD_DEBUGINFO --d2 NEW_DEBUGINFO OLD_RPM NEW_RPM

See the tool documentation for more information [2].

 *** Please, when closing bug as NOTABUG, provide a short justification ****

Comment 3 Jakub Hrozek 2016-04-18 15:55:51 UTC
Added functions are fine.

A size of an opaque structure changed, which is also safe, because the API user can only access it through a pointer.

Closing.
