Hello,
It's my first post on a mailing list, and non-native English speaker, so
sorry for any inconveniences.
There is an old e-mail (May 2012), viewable on
sourceforge.net/p/cygwin-ports/mailman/message/29275412, about a problem
running lrzip on Cygwin. The only response says "will look into it further",
and I could not find anything on the net. As I really want to run lrzip on
Cygwin, I decided to try my luck on this issue. Got the latest version from
lrzip's git and built it, fired up GDB and started looking for the error.
This is my progress on the issue, so if anybody is interested and wants to
help, too:
As it seems, in rzip.c, function hash_search, there is a mutex that is
locked on one thread and then unlocked in another. This is undefined
behavior. So what I found is that the error occurs because thread A locks
the mutex, thread B tries to unlock it and fails because it belongs to A. In
Linux this may be working but not in Windows.
Out of time now, but I will try rewriting these locks soon.
Thanks,
Caio
