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. Regards, Jan
