There are many ways how to solve this problem, unfortunately nobody knows what
is your problem, there are too many close but still different problems in this
basket. You have delivered solution without stating the problem first.
(1) There are two kinds of developers:
(a) PC (instruction) of the crash only
(b) full context with parameters, variables and wanting even more.
(2) There are also two different kinds of developers:
(a) dependency on network services (like ABRT Retrace Server) is OK
(b) everything must work with full feature set even offline.
(3) And yet more two different kinds of developers:
(a) we must not upload anything for security reasons
(b) we can freely upload anything because Fedora already has no security.
- we already freely download+execute Mozilla binary plugins not reviewed
+ signed by Fedora Project, 99%(?) people install Flash anyway etc.
(4) And yet more two different kinds of developers:
(a) desktop ones who have thousands of BZs and ignore any ABRT BZ anyway
They are more interested in stats in which parts it crashes the most.
(b) at least Tools ones who check each BZ and have more problem that some
crashes repeat but they are not reproducible and even rich backtraces in
many cases do not contain enough info and it would be best to extend the
backtraces/bugreports even more.
There are various other solutions still keeping high quality backtraces such
(x) Already stated fast core files upload to ABRT Retrace Server via gdbserver.
(y) With F-18 shorted .debug files
downloading specific .debug.xz files can be much faster than whole
(z) Symbol server for GDB - no need to download full debuginfos, GDB fetches
only parts on demand.
Maybe other solutions but it depends which of the 16 combinations of the (1),
(2), (3) and (4) use cases above you choose.
