* Fix segfault from inconsistent macro use.Gravatar Edward Z. Yang2016-09-07

* Don't use readdir_r if deprecatedGravatar Erik de Castro Lopo2016-09-07
| | | | | | | | | | | | | | | GNU glibc 2.23 and later deprecate `readdir_r` in favour of plain old `readdir` which in some upcoming POSIX standard is going to required to be re-entrant. Eventually we want to drop `readder_r` all together, but want to be compatible with older unixen which may not have a re-entrant `readdir`. Solution is to make systems with *known* re-entrant `readir` use that and use `readdir_r` whereever we have it and don't *know* that `readdir` is re-entrant. Closes: https://github.com/haskell/unix/issues/70
* Use `#const` rather than FFI wrapper for PATH_MAXGravatar Herbert Valerio Riedel2016-01-31
| | | | This has the side-effect of making two more modules `Safe`-inferred

|
* Avoid redundant prototypes for ptsname(3) et alGravatar Herbert Valerio Riedel2016-01-31
| | | | | This is now possible since we now use `AC_USE_SYSTEM_EXTENSIONS`, which indirectly enables _XOPEN_SOURCE
* Replace `__hsunix_nanosleep` wrapper with CApiFFIGravatar Herbert Valerio Riedel2016-01-31
|
* Remove obsolete windows-related #ifdefsGravatar Herbert Valerio Riedel2016-01-31
| | | | | | We haven't properly supported Windows for some time now, and we wouldn't have any way to test anyway, since GHC doesn't support Cygwin anymore either.

|
* Simplify code via AC_USE_SYSTEM_EXTENSIONSGravatar Herbert Valerio Riedel2015-12-03
| | | | | `AC_USE_SYSTEM_EXTENSIONS` takes care of defining feature_test_macros(7) thereby allowing us to remove a few manual `#define`s
* Don't assume non-POSIX `WCOREDUMP(x)` macro existsGravatar Herbert Valerio Riedel2015-11-16
| | | | This fixes #50
* Fix SIGINFO and SIGWINCH.Gravatar Erik de Castro Lopo2014-12-19
| | | | | | | | | | | | It seems these two signals have not been working since at least 2009. Detection of these signals seems to have never been added to the configure.ac script and the code guarded by #ifdef then bit-rotted (the idiom used to handle these signals seems to have been abandoned for something simpler/better in 2009). This fix simply handles these signals the same way the other signals are handled in System/Posix/Signals.hsc. Closes #30 and #31
* Tweak execvpe.h hack (see 256b19184bcb) some moreGravatar Herbert Valerio Riedel2014-12-07

* Have "execvpe.h" provide execvpe() againGravatar Herbert Valerio Riedel2014-12-06
| | | | | | Turns out `process` reuses `unix`'s execvpe() implementation, and the refactoring in f24ba78f68b2cbc4f4afadc8dd60fc2935357255 broke process.
* Retry process execution in case of ENOTDIRGravatar Iku Iwasa2014-12-06
| | | | | | | If `PATH` environment variable contains non directory component, `__hsunix_execvpe()` failed by `ENOTDIR`. This fixes #11 for all platforms.
* Refactor local `execvpe(3)` implementationGravatar Herbert Valerio Riedel2014-12-06
| | | | | | | | | | | | | | | | | The previous code was prone to conflicts with when the platform happens to expose a `execvpe(3)` implementation in its libc. This commit renames the internal implementation to `__hsunix_execvpe` as well as adding an autoconf-detection for the presence of `execvpe(3)`, in which case `__hsunix_execvpe()` forwards the call to `execvpe(3)`. Moreover, the code has been cleaned up to remove likely bitrotted CPP conditionals. This should fix #22 (This also partially addresses #11 on platforms which have a libc-provided `execvpe(3)`)
* Indicate whether a process dumped core in the ProcessStatusGravatar Simon Marlow2013-01-25
| | | | | | | | | | | | | | | The Bool field of Terminated is new, as is the documentation: data ProcessStatus = Exited ExitCode -- ^ the process exited by calling -- @exit()@ or returning from @main@ | Terminated Signal Bool -- ^ the process was terminated by a -- signal, the @Bool@ is @True@ if a core -- dump was produced | Stopped Signal -- ^ the process was stopped by a signal deriving (Eq, Ord, Show) This is an API change, hence will need a major version bump.

* NetBSD does not have support for symbol versioning, so updated systenGravatar Simon Marlow2009-07-23
| | | | | | | | | | | | | | | | | | functions need to be given a new name, and the header files contain some __asm hackery in order to let the program call the correct function. This mean that you need to use the header files in order to call the correct system functions, which prevents things like "foreign import ccall" from working. Ghc solves this with wrapper functions for some of the renamed functions, but it has not been updated for newer versions of NetBSD that has recently versioned some more functions. The attached patches introduces wrapper functions for all currently NetBSD-versioned functions used in libraries/unix. Solves ~20 testsuite failures.

* Move directory stuff from base to hereGravatar Simon Marlow2009-06-25
| | | | leaving out Windows-specific hacks
* Don't put inline'd functions in HsUnix.h; fixes trac #2969Gravatar Ian Lynagh2009-02-11
| | | | | | If they are included into a C file which also has certain symbols defined, then the behaviour of the HsUnix.h functions can change (e.g. lstat can become the 32bit, rather than 64bit, version).
* move some stuff here from System.Directory, now the dependencies are reversedGravatar Simon Marlow2008-08-21

* in pPrPr_disableITimers (who made up that name?) call the RTS to disable the ↵Gravatar Simon Marlow2007-09-12
| | | | | | | | | timer Since we switched to using timer_create() in the RTS, this function has been failing to disables the timer interrupts. This turns out to be the cause of the random framework failures in the test suite. Invoking the RTS to turn off the timer signal is the right thing.

* [project @ 2004-09-29 15:50:54 by simonmar]Gravatar simonmar2004-09-29
| | | | | | | | | | | | | | Process reorganisation: the System.Process library moves into base, and System.Cmd is re-implemented in terms of it. Thanks to Krasimir Angelov, we have a version of System.Process that doesn't rely on the unix or Win32 libraries. Normally using unix/Win32 would be the right thing, but since we want to implement System.Cmd on top of this, and GHC uses System.Cmd, we can't introduce a bunch of .hsc dependencies into GHC's bootstrap libraries. So, the new version is larger, but has fewer dependencies. I imagine it shouldn't be too hard to port to other compilers.
