nathanw ee45767b84 printf format fixes. 2003-01-27 20:54:26 +00:00
nathanw 9ff1e2d385 Make pthread_barrier_wait() handle spurious wakeups from pthread__block() 
by adding a generation number to the barrier structure and incrementing it
when the barrier fires.

XXX this is an ABI change for anything using barriers, but the library is
new enough and nothing in the tree uses barriers so I'm going to let it
slide. Using the private data pointer for a field that will always be present
would be excessive.

nathanw fe8e8dad4a More signal rearranging: 
- Signal handlers now simply continue executing the current thread,
   rather than trying to put themselves back on the queue that they came
   from, which was rather fragile. As a result, all callers of
   pthread__block() must be prepared to handle spurious wakeups.

 - When a signal arrives for a thread that is blocked in the kernel,
   note this in another field in pthread_st and set a flag. Process the
   signal and set up the trampoline for the handler *after* the thread
   unblocks, so that both the trampoline and the returned state from
   the kernel are preserved.

 - Factor out some code into a pthread__deliver_signal() routine;
   the signal-taking code in pthread_sigmask() should be able to use this
   soon.

This is still gross, and there are still some terrible MP issues lurking here,
but progress crawls along.

scw b5ca8aee09 Yay! Working pthreads for sh5. 2003-01-22 13:52:48 +00:00
scw 04c6e0b141 pthread__lock_ras_start and pthread__lock_ras_end need to be declared 
as function pointers, not character arrays, for the benefit of
platforms (e.g. SH5) where the two types are quite distinct.

scw 5f7bdeae84 Need to include <string.h> for memcmp() prototype. 2003-01-22 13:49:14 +00:00
nathanw dc651e62df Don't bother acquiring the tsd_lock and reading the destructor function 
if the corresponding TSD entry is empty.

Cuts down lock/unlock pairs for this operation from 256 to the number
of active TSD entries; sicne this is done when every thread exits, it saves
many total lock/unlock pairs.

thorpej 7dc01dbfab Add some threadlib stubs that are used by X: 
* thr_create() (stub in libc aborts)
* thr_exit() (stub in libc calls exit())
* thr_yield() (stub in libc does nothing)

Also make the libc thr_self() stub not abort.

XXX Should we add thrattr_*() stubs for setting the detach-state?

thorpej 9b29af3e07 Remove the dummy stack attr routines -- best to catch broken applications 
and fix them to use the proper feature test instead (as has already been
done with the openldap package).
 2003-01-19 20:58:00 +00:00
thorpej 592409d356 Add mutexattr_init(), mutexattr_destroy(), and mutexattr_settype() (recursive 
mutexes are used by the X libraries).
 2003-01-19 20:46:11 +00:00
thorpej 439830cb08 Always allow includes to be installed. This makes it easier for 
people to get straggling ports bootstrapped (pthread.h is required
in order to build libc).
 2003-01-19 19:55:13 +00:00
skrll 023fed95bf Move _POSIX_THREADS to the right place and define a few other symbolic 
constants for the features we gained with the merge of the nathanw_sa
branch.

Ok'd by thorpej.

Closes my PR 19930.

wiz d44e858cbb Remove another variable name. 2003-01-19 19:21:49 +00:00
christos 1b36c15f8d - constify the get functions 
- remove argument variable names since they pollute the namespace
- add mock implementation of the missing stack functions
XXX: we need to do this right [i.e. actually get and set sizes and addresses]
but the current stack setup makes this a bit complicated.

jdolecek 0b3f936d86 'destructor' is a bit too generic; use 'destruct' instead for
