In Feb 2006, I submitted some libuwind patches [1], which were
motivated by my inability to tolerate a horribly outdated linux
distribution at my employer at the time. I was trying to develop on a
newer x86_64 distro that didn't have frame pointers and had to support
heap profiling.
A decade has passed, the world has moved on and as you may have
noticed, I haven't done a great job of keeping up with patches.
Fortunately, Dave Watson has stepped up to take over. As you may have
noticed he has been posting patches to the mailing list and has made a
queue of all patches posted to the list in the last year or so. He'll
be going through them, vetting them and will be looking to make a more
current release in the coming months.
I believe libunwind continues to have a special place in the community
after all these years because of the unique value it provides. Use it
anywhere you want -- that includes any hardware, anywhere in your code
(including malloc), many open source OSes, any type of software -- and
still get a stack trace.
I'll continue to be active on other open source projects. I've met a
lot of great people over the years due to my association with
libunwind. Thank you for everything. Please support Dave with testing
(I'm thinking of you aarch64 and mips folks) and reviews he needs to
make libunwind more awesome.
