[darkserver] darkclient is not packaged + it is slow

[Jan Kratochvil]

Hi,

I wanted to use darkserver/darkclient for the core file
	https://bugzilla.redhat.com/show_bug.cgi?id=926099#c16
but

(1) I haven't found darkclient packaged in Fedora, so I used:
	git clone git://github.com/kushaldas/darkclient.git
    also it took me some time before I found it.

(2) It is very very slow.  First I generated list of NVRAs from build-ids
    ./darkclient >1 -i 1c07c6884a1cb3c93486fd902e656b3fd492cb19 ...
dd7d265b52c0fedd7fb5e5c48e6e39b8581fe8cb
    which is reasonably fast (0m3.388s).

    But then to get the URLs is terribly slow.  I haven't found how to run
    darkclient with multiple arguments for -p so I had to run it for each one:
    time for i in `cat 1`;do ./darkclient -p $i;done|tee 2

    But it took 11m23.545s.  That was yesterday - today it took just 0m39.128s;
    that's also not great but it is at least usable.

(3) I had to somehow merge the lists of NVRA packages - each build-id
    generates possibly multiple NVRAs.  But the final list of NVRAs should be
    intersection of all NVRAs for each N (name) across all the build-ids.
    Maybe this could be a part of the darkclient; although
    darkserver/darkclient is not a whole solution - that ABRT tries to do.
    Attached FYI.

Jan
