            Bug ID: 15989
           Summary: Native support for compressed core files
           Product: gdb
           Version: 7.6
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: corefiles
          Assignee: unassigned at sourceware dot org
          Reporter: sourceware-bugs at trk dot nickurak.ca

In my environment, cores are huge, so naturally we have them compressed all the
time.

It would be really *really* convenient to not have to decompress the core files
and store them on disk (a process that can take several minutes) just to spend
10 seconds looking at a backtrace to go "a ha!". If GDB supported reading
especially gzipped core files natively, it would be a big help.

You should be able to get that transparently at the filesystem level, with
something like fuse's archivemount.

One (probably easy to solve) problem with something like fuse archivemount is,
that it only mounts archives, so you have to create a tar.gz from it. Those
file formats complicate things somewhat, and generally people do just want to
compress the files (I do it with xz btw., which makes them factors smaller than
gz)

Another point is (and I stumbled over this report because I wanted such a
feature too) that you often have to debug on systems where this is not
possible. In a company you don't have the necessary priviliges to install the
fuse stuff, your kernel and/or userspace tools are too old. And you have to
debug on the system where the core file is, because you have no other system
with the same .so files and other stuff installed. It might be on a customers
machine where all you have is your statically linked gdb...

It might not be desireable to pull dependencies of compression libraries in,
but maybe gdb can support them via dlopen, and then support gz/bz2/xz/whatever
if it is present.

Using fuse would just be a hack, native support inside gdb would be much more
useful.

Opening and Writing coredumps compressed would be really useful, even if
opening it just means that there's an automated uncompress under $TMP and then
the resulting file is opened as "normal" coredump.
