| 2020-12-30 | libthread: simplify | Russ Cox | 1 | -207/+10 | |
| Now that everything uses pthreads and pthreadperthread, can delete various conditionals, all the custom context code, and so on. Also update documents. Fixes #355. | |||||

| 2020-12-30 | libthread: add threadmaybackground | Russ Cox | 1 | -1/+1 | |
| Programs that want to background themselves now need to define threadmaybackground returning 1. This avoids a confusing (to people and debuggers) extra parent process for all the threaded programs that will never want to background themselves. | |||||
| 2020-12-15 | libthread: fix use after free of first thread in each proc | Russ Cox | 1 | -1/+9 | |
| This was causing sporadic but frequent crashes at startup in 9pserve on the new M1 Macs, correctly diagnosing a use-after-free. | |||||
| 2020-05-17 | libthread: handle spurious _procsleep wakeups, fix $LIBTHREAD handling | Russ Cox | 1 | -5/+23 | |
| 2020-05-17 | libthread: add pthreadperthread mode and use under ASAN | Russ Cox | 1 | -6/+64 | |
| ASAN can't deal with the coroutine stacks. In theory we can call into ASAN runtime to let it know about them, but ASAN still has problems with fork or exit happening from a non-system stack. Bypass all possible problems by just having a full OS thread for each libthread thread. The threads are still cooperatively scheduled within a proc (in thos mode, a group of OS threads). Setting the environment variable LIBTHREAD=pthreadperthread will enable the pthreadperthread mode, as will building with CC9FLAGS='-fsanitize=address' in $PLAN9/config. This solution is much more general than ASAN - for example if you are trying to find all the thread stacks in a reproducible crash you can use pthreadperthread mode with any debugger that knows only about OS threads. | |||||

| 2020-01-14 | libthread: use mmap to allocate OpenBSD stacks | Russ Cox | 1 | -2/+7 | |
| Should fix faults on OpenBSD. Fixes #218. Fixes #226. | |||||
| 2020-01-13 | libthread: fix fault in teardown of proc | Russ Cox | 1 | -0/+1 | |
| Fixes #332. | |||||
| 2020-01-12 | libthread: run first thread in proc on system stack | Russ Cox | 1 | -14/+45 | |
| For pthread systems that are fussy about which stack is used, this makes sure that threadmain runs on a system stack. If you only use proccreate (never threadcreate), all threads run on system stacks. | |||||
| 2020-01-10 | Trivial changes: whitespace and modes. | Dan Cross | 1 | -13/+11 | |
| Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net> | |||||

| 2005-01-23 | Apparently SuSE 9.1's X distribution uses even bigger | rsc | 1 | -1/+1 | |
| buffers than the standard ones. 64kB appears to be enough for a stack in that case, but let's just go nuts and make the stacks enormous, so that it takes a few more doublings of X's stack needs before we run into this problem again. The VM system should take care of not actually using most of the memory anyway. | |||||
