            Bug ID: 21568
           Summary: Temporary directories created by abipkgdiff doesn't
                    get deleted when fedabipkgdiff runs with option -a
           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: ---

abipkgidiff tool creates temporary directory to keep extracted rpms to perform
ABI comparison against two set of packages. After successful execution,
temporary directory gets deleted unless option --keep-tmp-files is passed.
Normally, it works as per expectation but when fedabipkgdiff tool executes with
option -a, it doesn't.

Steps to reproduce: 
$ ls ~/.cache/libabigail/ |wc
0

$ tools/fedabipkgdiff -a --from fc25 --to fc26 libxcb

$ echo $?
0

$ ls ~/.cache/libabigail/ |wc
 7
$ $  du -chs  ~/.cache/libabigail/
404M    /home/skumari/.cache/libabigail/
404M    total

Expected behavior
-----------------
Directory ~/.cache/libabigail/ should be empty

Additional Information:
-----------------------
I don't see anywhere in fedabipgdiff source code passing option
--keep-tmp-files to abipkgdiff

When -a option is not used i.e running "tools/fedabipkgdiff --from fc25 --to
fc26 libxcb " deletes all temporary directories.
