Around a year and a half ago, I’ve asked my former company for some time to
work on an issue that was impacting the debugging capabilities in our project:
gdbserver couldn’t debug multithreaded applications running on a PowerPC32
architecture. The connection to the gdbserver was broken and it couldn’t
control the debug session anymore. Multiple people have already investigated
this problem and I had a good starting point, but we still weren’t sure in
which software component the issue lied: it could have been the toolchain, the
gdbserver, the Linux kernel or the custom patches we applied on top of the
kernel tree. We were quite far away from finding the root cause.
Between the initial patch and the maintainer’s patch there was a private conversation between me and the maintainer (I don’t have access to it because I’ve used my work email and since then I switched companies). I posted my reworked patch only for visibility, since by then they have accepted the maintainer’s patch. But I sent the reworked patch in private to the PowerPC maintainer, before sending it to the powerpc mailing list.
