Python API equivalent of 'info sharedlibrary'

Python API equivalent of 'info sharedlibrary'

[Dominik Czarnota]

Hi,

Is there any Python API equivalent of getting information about shared
libraries through the `info sharedlibrary` command?

If not, is there any chance that this gets added?

I know there is `gdb.objfiles()` but it seems it goes over all object
files [0] and does not really provide as much information as the `info
sharedlibrary` command [1].

In our plugin we try to figure out the exact path of the glibc library
and we want to support all possible use cases (gdb, gdbserver,
LD_PRELOAD, gdbstub from QEMU-user etc.). Of course this will always
be a heuristic since we can never know if a libc.so is actually a libc
and so on. We are currently parsing the output of the `info
sharedlibrary` command but this gets more and more complicated which
is not great... [2].

No.

It would certainly be ok to add, but I don't know of anybody with plans
to work on it.
