2021-01-14organize std lib concurrency primitives and add RwLockAndrew Kelley
* move concurrency primitives that always operate on kernel threads to the std.Thread namespace * remove std.SpinLock. Nobody should use this in a non-freestanding environment; the other primitives are always preferable. In freestanding, it will be necessary to put custom spin logic in there, so there are no use cases for a std lib version. * move some std lib files to the top level fields convention * add std.Thread.spinLoopHint * add std.Thread.Condition * add std.Thread.Semaphore * new implementation of std.Thread.Mutex for Windows and non-pthreads Linux * add std.Thread.RwLock Implementations provided by @kprotty

... and mem.copy operations. Requires slightly larger input buffers than result length. Add helper functions std.mem.alignInBytes and std.mem.alignInSlice.

2021-01-11std.os.windows.GetFinalPathNameByHandle: replace kernel32 by ntdll callRohlem
Removes the call to kernel32.GetFinalPathNameByHandleW in favor of NtQueryObject, which means we can reuse the other codepath's logic for DOS naming.

The NtQueryInformationFile with .FileNormalizedNameInformation is only available in Windows 10 1803 (rs4) and later, however there is probably still another route we can go via ntdll.

2021-01-06fix LRESULT and LPARAM typedefsJonathan Marler
LRESULT and LPARAM are currently typedef'd as ?*c_void, however, they are supposed to be typedef'd as LONG_PTR which is equivalent to isize in Zig.

2020-12-29std.ChildProcess: improvements to collectOutputPosixAndrew Kelley
* read directly into the ArrayList buffers. * respect max_output_bytes * std.ArrayList: - make `allocatedSlice` public. - add `unusedCapacitySlice`. I removed the Windows implementation of this stuff; I am doing a partial merge of LemonBoy's patch with the understanding that a later patch can add the Windows implementation after it is vetted.

2020-12-29std: Avoid deadlocking in ChildProcess.execLemonBoy
Reading stdin&stderr at different times may lead to nasty deadlocks (eg. when stdout is read before stderr and the child process doesn't write anything onto stdout). Implement a polling mechanism to make sure this won't happen: we read data from stderr/stdout as it becomes ready and then it's copied into an ArrayList provided by the user, avoiding any kind of blocking read.

2020-12-23Truncate user and group ids for 64 bit Linux systems (#7466)Andreas Linz
* Truncate user and group ids Calls to `getuid`, `getgid` and their `eid` variants fail to compile on 64bit Linux systems because the return value of the syscall is of `usize` and needs to be truncated to fit the size of `uid_t` that is 32 bit. Thanks to @FireFox317 for figuring this out in Zig's Discord channel! * Add a regression test for user and group ids * Replace @truncate with @intCast This should be safe because `uid_t` will be 32-bit. * Add missing import for getauxval * Add missing package names * Revert "Add missing import for getauxval" This reverts commit 38f93dc89effdf657f2b81a56b96527ce4083f52. * Skip user and group test if builtin.link_libc

2020-12-18std.crypto.random: introduce fork safetyAndrew Kelley
Everybody gets what they want! * AT_RANDOM is completely ignored. * On Linux, MADV_WIPEONFORK is used to provide fork safety. * On pthread systems, `pthread_atfork` is used to provide fork safety. * For systems that do not have the capability to provide fork safety, the implementation falls back to calling getrandom() every time. * If madvise is unavailable or returns an error, or pthread_atfork fails for whatever reason, it falls back to calling getrandom() every time. * Applications may choose to opt-out of fork safety. * Applications may choose to opt-in to unconditionally calling getrandom() for every call to std.crypto.random.fillFn. * Added `std.meta.globalOption`. * Added `std.os.madvise` and related bits. * Bumped up the size of the main thread TLS buffer. See the comment there for justification. * Simpler hot path in TLS initialization.
2020-12-18std: Properly fix the TLS alignment problemLemonBoy
ad05509 introduced a fix for the wrong problem, the logic to align the start of main_thread_tls_buffer was already there but was flawed. Fix it for good and avoid wasting too many bytes for alignment purposes.
