* static build: fix internal locking weaks to get pulled in alwaysTimo Teras2010-05-072-41/+0
| | | | | | | | | | | Linker is smart and does not pull in weaks.os, ever. This happens because that compilation unit does not get strong references and ld eliminates dead code. We really need the weaks for static build in a compilation unit that is always there, otherwise it won't work.

* nptl: fix libc internal, dynamically enabled lockingTimo Teräs2010-04-222-0/+41
| | | | | | | | | | | | | | | | | | | | | Final iteration to fix libc internal locking if libpthread is pulled in by dlopen call (directly or indirectly). We cannot really use the weak symbol trick for shared build, since the symbols won't get refreshed if libpthread is pulled in dynamically. In glibc, they have #ifdef SHARED magic to either use pthread_functions table, or weaks. But as we shared object files with both builds, this does not sounds good either. The reintroduces the libc weaks.c, but uses them now only with static build. For dynamic build, we still use the symbols with same name, but provide weaks in forward.c so they end up dereferencing the pthread_functions table indirectly if we are not linked to libpthread. Mutex initialization is hard coded as inline, as it needs to happen even if libpthread is not initially loaded.

* libc: remove libc weak __pthreads_* wrappersTimo Teras2010-04-163-73/+0
| | | | | | | | | | | | | | | | | It is not possible to override for libpthread to override the weak libc definitions. This has never worked in uclibc, and does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK). The proper thing to do is have weak prototypes in libc, and definitions in libpthread only. This way libc runs even if those functions are not defined, but just needs to protect against the NULL values (done by implementing __uclibc_maybe_call). This fix the problems if libc is linked before libpthread or if libpthread is pulled by a dependency library.

| | | | | | | | | | | Hi Erik It seems to me that __pthread_once and __pthread_initialize_minimal could be made WEAKs with no stub. The code in rpc_thread.c and __uClibc_main.c appears to expect this. Also, __pthread_return_0 __pthread_return_1 and __pthread_return_void can be static, not to pollute the name space. Jocke
* My mistake. We do need some weak pthread_* funcs. But we were previouslyManuel Novoa III2004-01-041-2/+87
| | | | | | | missing one in the glibc abi, and including a number of extras (which I left in commented). Unfortunately, this brings back the perl pthread bug. Fixing the incorrect weaks in libpthread wasn't sufficient to escape the shared loader bug. :-(
* Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III2003-12-271-69/+4
| | | | | | | | | | | | | | | | were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
