2018-06-20Update license notices in all C filesAndy Wingo1-17/+17
Update to newest recommended license notices from the FSF. Everything stays LGPLv3+ except guile-readline which is GPLv3+.
2018-06-20Remove (C) from copyright statementsAndy Wingo1-1/+1
As the FSF advises, 'There is no legal significance to using the three-character sequence “(C)”, but it does no harm.' It does take up space though! For that reason, we remove it here from our C files.

2012-02-23Revert "add pthread_atfork helpers to our threading shims"Andy Wingo1-9/+1
This reverts commit 2f745b64a1eb06e9e175a1b497d5270bebff9097.
2012-02-17add pthread_atfork helpers to our threading shimsAndy Wingo1-1/+9
* libguile/null-threads.h: * libguile/pthread-threads.h (SCM_DEFINE_ATFORK_HANDLERS_FOR_MUTEX) (scm_i_pthread_atfork): Define a pthread_atfork shim, and a helper to declare procedures to lock and unlock a mutex. * libguile/threads.h (SCM_PTHREAD_ATFORK_LOCK_STATIC_MUTEX): New macro, causes the snarfer to emit a pthread_atfork call to lock a mutex, if threads are enabled.
2011-05-26remove gc pthread redirects entirelyAndy Wingo1-18/+2
* libguile/pthread-threads.h: As an experiment, just define scm_i_pthread_create et al to their pthread_* functions, instead of the GC_ ones. It seems sufficient, given that all uses of Guile have to go through scm_with_guile anyway... Passes tests on my machine. Committing to give buildbots a go at it.
2011-04-03pthread-threads.h: only redirect to GC_pthread_sigmask if it is presentAndy Wingo1-0/+4
* configure.ac: Check for pthread_sigmask. * libguile/gen-scmconfig.c: Create SCM_HAVE_GC_PTHREAD_SIGMASK. * libguile/pthread-threads.h (scm_i_pthread_sigmask): Only redirect to GC_pthread_sigmask if GC_pthread_sigmask is present.
2011-03-29fix compilation with libgc 7.0, 7.1Andy Wingo1-0/+11
* configure.ac: Check for GC_pthread_exit and GC_pthread_cancel. * libguile/gen-scmconfig.c: Write HAVE_GC_PTHREAD_CANCEL and HAVE_GC_PTHREAD_EXIT into scmconfig.h. * libguile/pthread-threads.h (scm_i_pthread_exit, scm_i_pthread_cancel): Only redefine to their GC_pthread_* variants if we have those functions, which is not the case in libgc < 7.2.
2011-03-25threading / with_guile refactor to use more GC_stack_baseAndy Wingo1-7/+7
* libguile/init.h: * libguile/init.c (scm_i_init_guile): Change arg to this internal function from SCM_STACKITEM* to void*. Actually it's a struct GC_stack_base*. * libguile/bdw-gc.h: Don't do pthread redirects, because we don't want to affect applications' pthread_* bindings. * libguile/pthread-threads.h (scm_i_pthread_create) (scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel) (scm_i_pthread_sigmask): Do pthread redirects here, in this internal header. * libguile/threads.h: Remove declaration of internal scm_i_with_guile_and_parent. Remove declaration of undefined scm_threads_init_first_thread. Make declaration of internal scm_threads_prehistory actually internal, and take a void* (actually a struct GC_stack_base*). * libguile/threads.c (GC_get_stack_base): Implement a shim if this function is unavailable, and fold in the implementations of get_thread_stack_base. (GC_call_with_stack_base): Actually implement. (guilify_self_1): Take a GC_stack_base* as an arg. (scm_i_init_thread_for_guile): Likewise, and set up libgc for registration of other threads. (scm_init_guile): Use GC_get_stack_base instead of our own guesswork. (with_guile_and_parent, scm_i_with_guile_and_parent): Rework to trampoline through a GC_call_with_stack_base. (scm_threads_prehistory): Pass the "base" arg on to guilify_self_1.
2009-09-14Rename "boehm-gc.h" to "bdw-gc.h"; add to the distribution.Ludovic Courtès1-1/+1
* libguile/Makefile.am (modinclude_HEADERS): Add `bdw-gc.h'. * libguile/bdw-gc.h: Rename from "boehm-gc.h"; users updated. Update to LGPLv3+.

2002-12-16* pthread-threads.c, pthread-threads.h (SCM_DEBUG_THREADS): AddedMikael Djurfeldt1-1/+10
support for debugging mutex operations.
2002-12-16* threads.c (scm_thread): Removed filed joining_threads.Mikael Djurfeldt1-11/+41
(thread_print): Print thread number as well as address of thread structure. (scm_join_thread): Bugfix. (scm_lock_mutex, scm_try_mutex, scm_unlock_mutex, scm_timed_wait_condition_variable, scm_signal_condition_variable, scm_broadcast_condition_variable): Use the low-level API. (scm_all_threads): Return copy of thread list (to prevent unintended destruction). (scm_threads_prehistory): Initialize heap_mutex of fake thread.
2002-12-16* pthread-threads.c, pthread-threads.h, threads.c: Fixes toMikael Djurfeldt1-7/+13
pthread "native" recursive mutex support.
2002-12-15* __scm.h (SCM_DEFER_INTS, SCM_ALLOW_INTS): New definitions.Mikael Djurfeldt1-0/+24
Simply lock a thread C API recursive mutex. (SCM_NONREC_CRITICAL_SECTION_START, SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, SCM_REC_CRITICAL_SECTION_END): Removed. * eval.c: Replaced SOURCE_SECTION_START / SOURCE_SECTION_END with direct calls to scm_rec_mutex_lock / unlock around the three calls to scm_m_expand_body. * eval.c, eval.h (promise_free): New function. (scm_force): Rewritten; Now thread-safe; Removed SCM_DEFER/ALLOW_INTS. * pthread-threads.h: Added partially implemented plugin interface for recursive mutexes. These are, for now, only intended to be used internally within the Guile implementation. * pthread-threads.c: New file. * threads.c: Conditionally #include "pthread-threads.c". * eval.c, eval.h (scm_makprom, scm_force): Rewritten to be thread-safe; * snarf.h (SCM_MUTEX, SCM_GLOBAL_MUTEX, SCM_REC_MUTEX, SCM_GLOBAL_REC_MUTEX): New macros. * eval.c, threads.c, threads.h, snarf.h: Rewrote critical section macros---use mutexes instead. * tags.h (SCM_IM_FUTURE): New tag. * eval.c (scm_m_future): New primitive macro. (SCM_CEVAL): Support futures. (unmemocopy): Support unmemoization of futures. * print.c (scm_isymnames): Name of future isym.
2002-12-09* __scm.h (SCM_ALLOW_INTS_ONLY): Removed.Mikael Djurfeldt1-30/+33
(SCM_NONREC_CRITICAL_SECTION_START, SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START, SCM_REC_CRITICAL_SECTION_END): New macros. (SCM_CRITICAL_SECTION_START/END): Defined here. * eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around the three calls to scm_m_expand_body. * gc.h: #include "libguile/pthread-threads.h"; (SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros. * gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type scm_t_key; * gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist access. * gc-freelist.c (scm_gc_init_freelist): Create freelist keys. * gc-freelist.c, threads.c (really_launch): Use SCM_FREELIST_CREATE. * gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory): * gc.c (scm_i_expensive_validation_check, scm_gc, scm_gc_for_newcell): Put threads to sleep before doing GC-related heap administration so that those pieces of code are executed single-threaded. We might consider rewriting these code sections in terms of a "call_gc_code_singly_threaded" construct instead of calling the pair of scm_i_thread_put_to_sleep () and scm_i_thread_wake_up (). Also, we would want to have as many of these sections eleminated. * init.c (scm_init_guile_1): Call scm_threads_prehistory. * inline.h: #include "libguile/threads.h" * pthread-threads.h: Macros now conform more closely to the pthreads interface.

(USE_PTHREAD_THREADS): Define if pthreads configured.
2002-12-02* pthread-threads.h: New, implement pthread-like API by deferring toMarius Vollmer1-0/+99
pthread itself.
