  • 85272c48b9 Improve some comments, minor tweaks to GC. theraven 2011-06-23 10:30:10 +0000
  • 1f681c8464 Added some GC docs to the readme. theraven 2011-05-30 15:14:20 +0000
  • 61a2ae0f54 Make the canary check look at the address where the canary was stored, not the word before where the canary was stored. theraven 2011-05-30 11:19:44 +0000
  • 1c847cedd1 Remove GC_no_dls for now. This can be safely set if all static variables used to store pointers are id or are explicitly marked __strong, which is not (yet) the case in GNUstep. theraven 2011-05-30 11:13:25 +0000
  • 851328268c Expand the coverage of canaries to object allocations, expand logging to object allocations and all deallocations. It's now possible to implement malloc_history entirely parsing the dump file (or doing /dev/fd style tricks send it straight to a monitoring process). theraven 2011-05-29 22:13:35 +0000
  • c9e54c382d Tweak auto-copy code. Now it only copies classes that are explicitly registered to be copied on heap assignment. By default, this is just _NSConcreteStackBlock. Other classes can be registered (LanguageKit should register BlockClosure to make sure that Smalltalk works). theraven 2011-05-29 21:59:50 +0000
  • b296b18571 Improvements to GC mode: theraven 2011-05-29 21:28:27 +0000
  • ff1e691c3b And some more... theraven 2011-05-29 14:38:14 +0000
  • 4a78269815 Removed debugging line accidentally committed. theraven 2011-05-29 14:36:05 +0000
  • 4ffb19230f Make sure that the statics used to store internal tables are marked as roots. theraven 2011-05-29 14:27:41 +0000
  • 8f530849fd When assigning a pointer to an object that is allocated on the stack to the heap, send a -copy message. This lets you cast blocks to id and then assign them to ivars without anything breaking. Apple's 'solution' to this is to segfault, which is not particularly elegant. This code is also quite an ugly hack (it just checks whether the object is allocated within a couple of pages of the current stack frame), so I might remove it before release. theraven 2011-05-29 13:53:15 +0000
  • e7767baf50 Don't send retain / release messages in GC mode when copying object pointers into blocks. theraven 2011-05-29 13:50:46 +0000
  • d1199844cb Lock the GC mode once something has queried it. All of the GNUstep code that does run-time detection of whether to use GC calls objc_collecting_enabled() (sometimes indirectly, via NSGarbageCollector) to see if we're in GC mode. After any of these calls, it is not safe to switch modes. theraven 2011-05-28 15:10:03 +0000
  • fe5d1b892a Tweak GC check, make sure GC_init() is called even when ObjC code isn't using GC (stuff internal to the runtime may be) theraven 2011-05-28 14:38:02 +0000
  • d73eb8f634 Expose another function in the header. theraven 2011-05-28 13:24:24 +0000
  • 6d78040180 Initial support for running finalizers in a separate thread. theraven 2011-05-28 13:07:11 +0000
  • 0c8faf1961 Sometimes people assign things like classes to __weak pointers. This confuses the GC, because it expects to be able to finalize / delete things that are the target of disappearing links. theraven 2011-05-28 11:04:47 +0000

  • 0c72e2e418 Use typed allocations for the hash table entries. This makes sure that the GC won't treat the jump table bitfield as a pointer. theraven 2011-05-27 17:40:58 +0000
  • 32b4432ebc Add correct defines for threaded boehm-gc on linux. thebeing 2011-05-27 15:27:05 +0000
  • 2d9f41aa94 If we're linking against Boehm GC, then we may as well allow it to collect the runtime's hash tables, rather than doing that manually. theraven 2011-05-27 14:54:06 +0000
  • 7deef6854a Tweaked release announcement to reflect the fact that GC is built by default unless explicitly disabled. theraven 2011-05-27 14:30:57 +0000

  • 3769a48cd7 Add an ugly hack to prevent a clever optimiser from realising that it can completely optimise objc_clear_stack() away. theraven 2011-05-27 09:44:12 +0000
  • 5b2c24bed3 If LIBOBJC_DUMP_GC_STATUS_ON_SIGNAL is set, dump the GC state in response to kill -$(LIBOBJC_DUMP_GC_STATUS_ON_SIGNAL) {pid}. theraven 2011-05-26 22:08:27 +0000

  • fcc47bc7ce Fix building without GC support. Still need to make sure that some of the GC functions always work, since they are expected to be no-ops in non-GC mode. theraven 2011-05-25 12:25:27 +0000
  • 01237af0fc Add GC-aware property accessors (in GC mode, we don't need all of the atomic juggling, because the GC looks after that stuff for us). theraven 2011-05-25 12:15:58 +0000
