From a8a22295837aaadf39bfede6c92e9f9047bcaa34 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ccpp: add %h and %e parameter into abrt-hook-ccpp
Without this commit core_pattern's parameter %h and %e was not
translated at all.
If there is a white space in executable filename, %e replaced only by
the first part of executable name (till the space). Hence we decided
to get executable name from /proc/PID/exe symlink exist.
Example:
If 'core_pattern = core.%h.%p.%t.%e' the result was
core.%h.26284.1469805542.sleep not
core.myshostmane.26284.1469805542.sleep with spaces
Related to #1587891
