Re: Firefox/libthread_xu issue with pthread_attr_setschedparam
:> THR_MAX_PRIORITY(31), both defined in
:> lib/libthread_xu/thread/thr_private.h. When a value in the range [-20;
:> -1] is used, pthread_attr_setschedparam returns an error code of
:> ENOTSUPP, which NSPR doesn't like. More precisely, when Firefox is
:> compiled with the 'debug' pkgsrc option, an assert fails, abort() is
:> called and a coredump written.
:I thought we had fixed that some time ago already?
Nope, I'm looking at the code and it is definitely a problem. There
are a bunch of THR_ defines that are essentially not used by
the library at all, except for that (broken) range check.
The only thing that uses THR_MAX_PRIORITY is the m_ceiling
attribute in the mutex attribute structure, which we don't use
at all (and I think it operates in a private scheduling domain
I'll have a patch for people w/ the firefox setup to try in a moment.
