Feoramund fef5f526f3 Remove unneeded slicing in strings.clone 2025-03-05 13:54:31 -05:00
Feoramund 2ab1ca29e6 Fix data races in os2/env_linux.odin 
Switched to a recursive mutex so that procedures which need to perform
lookups can do so while also maintaining the lock across their entire
body in order to guarantee atomicity for each environment operation.
 2025-03-04 19:32:05 -05:00
Feoramund 179e5b9266 Fix typo 2025-03-04 19:12:45 -05:00

Feoramund 2d0dc44636 Shorten buffers used for os2.random_string results 
This is needed now that `os2.random_string` fills the whole slice.
 2025-03-03 19:18:54 -05:00
Feoramund d6002d68a2 Make os2.random_string use context.random_generator 
This removes the data race caused by multiple threads using the
unprotected global `random_string_seed`, so long as no two threads share
the same random generator; this is the default case.

Additionally, `os2.random_string` now takes into account the full buffer
slice given to it.

Feoramund 675bffce88 Add missing allocator in os2.file_info_clone 2025-03-02 17:22:43 -05:00
Feoramund 7d1fcfa09b Fix wrong path in os2.user_config_dir 2025-03-02 17:22:40 -05:00
Feoramund 6054b921db Add tests for new safe to_cstring 2025-02-27 18:54:38 -05:00
Feoramund b2e3b34ce0 Fix #4890 
`strings.to_cstring` previously would not check if the buffer could
handle the extra null byte and could lead to segmentation violations
when using the resulting string in an API expecting the terminator.
 2025-02-27 18:54:38 -05:00

Feoramund fec1ccd7a3 Fix data races in sync.Recursive_Benaphore 2024-09-11 08:39:23 -04:00
Feoramund b2c2235e58 Fix recursive_benaphore_try_lock 
Previously, if the owner called this, it would fail.
 2024-09-10 14:52:20 -04:00
Feoramund 3a60109180 Fix signalling test child threads crashing test 0 
A thread made inside a test does not share the test index of its parent,
so any time one of those threads failed an assert, it would tell the
runner to shutdown test index zero.
 2024-09-10 14:52:20 -04:00
Feoramund 074314b887 Fix data race in test_core_flags 2024-09-10 14:52:20 -04:00
Feoramund 8a14a656fb Fix chan.can_send for unbuffered channels 
`w_waiting` is the signal that says a caller is waiting to be able to
send something. It is incremented upon send and - in the case of an
unbuffered channel - it can only hold one message.

Therefore, check that `w_waiting` is zero instead.
 2024-09-10 14:52:20 -04:00
Feoramund e9a6a34480 Forbid chan.try_send on closed buffered channels 2024-09-10 14:52:20 -04:00
Feoramund 026aef69e3 Fix deadlock on sending to full, buffered, closed Chan 
This will also keep messages from being sent to closed, buffered
channels in general.
 2024-09-10 14:52:20 -04:00
Feoramund 73f5ab473c Keep chan.can_recv from deadlocking 2024-09-10 14:52:20 -04:00

Feoramund dbb783fbf2 Fix atomic memory order for sync.ticket_mutex_unlock 2024-09-09 16:19:15 -04:00
Feoramund 45da009377 Use more atomic handling of thread flags 
This can prevent a data race on Linux with `Self_Cleanup`.
 2024-09-09 16:19:15 -04:00
Feoramund 4d14b4257e Convert POSIX Thread to use semaphore instead 
One less value to store, and it should be less of a hack too.

Semaphores will not wait around if they have the go-ahead; they depend
on an internal value being non-zero, instead of whatever was loaded when
they started waiting, which is the case with a `Cond`.
 2024-09-09 16:19:14 -04:00
Feoramund cbd4d5e765 Fix data race in atomic_sema_wait_with_timeout 2024-09-09 16:19:14 -04:00
Feoramund 74b28f1ff9 Fix rare double-join possibility in POSIX thread._join 
This was occuring about 1/100 times with the test runner's thread pool.
 2024-09-09 16:19:14 -04:00
Feoramund 9d6f71fd2e Fix sync.Benaphore 
The calls to `atomic_add*` return the value before adding, not after, so
the previous code was causing the occasional data race.
 2024-09-09 16:19:14 -04:00
Feoramund 2f1228baa0 Add tests for Bit_Array 2024-09-03 17:23:42 -04:00

FeoramundandLaytan e7d6e2d163 Add documentation to os2.close 
Make it explicit that using a stream after closing is like a
use-after-free bug.
 2024-08-28 19:53:20 +02:00
FeoramundandLaytan 8b40be50b9 Update core:io tests 
- Relax return value requirements on errors. Only the error is checked,
  as there are multiple conflicting return styles throughout the `os`
  API.

  Some return the error along with `0`, `-1`, or another value. This can
  be smoothed out later.

- Test `os2` files now.
- No longer test streams after closing; this is considered similar to a
  use-after-free in `os2`.
