Cygwin: cwd: avoid releasing the cwdstuff SRW Lock twice cwdstuff::set has a code snippet handling the case where a process can't create a handle to a directory, e. g., due to permissions. Commit 88443b0a22589 ("cwdstuff: Don't leave from setting the CWD prematurely on init") introduced a special case to handle this situation at process initialization. It also introduces an early mutex release, which is not required, but ok, because we're in the init phase. Releasing the mutex twice is no problem since the mutexes are recursive. Fast forward to commit 0819679a7a210 ("Cygwin: cwd: use SRWLOCK instead of muto"). The mechanical change from a recursive mutex to a non-recursive SRWLOCK failed to notice that this very specific situation will release the SRWLOCK twice. Remove the superfluous release action. While at it, don't set dir to NULL, but h, since dir will get the value of h anyway later on. Setting h to NULL may not be necessary, but better safe than sorry.

Cygwin: let feraiseexcept actually raise an exception The exception handling inside of Cygwin functions marked as SIGFE covers exceptions and lets the library code handle them gracefully. If these functions want to raise an exception, they have to send a signal explicitely via raise(3). That's not what we want in feraiseexcept(). It triggers a floating point exception explicitely by calling the i387 op "fwait". Being marked as SIGFE, this exception will be suppressed and the normal exception handling won't kick in. Fix this by moving feraiseexcept into the NOSIGFE realm. Fixes: 0f81b5d4bcaa ("* Makefile.in (DLL_OFILES): Add new fenv.o module.") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

Fix profiler error() definition and usage Minor updates to profiler and gmondump, which share some code: - fix operation of error() so it actually works as intended - resize 4K-size auto buffer reservations to BUFSIZ (==1K) - remove trailing '\n' from 2nd arg on error() calls everywhere - provide consistent annotation of Windows error number displays Fixes: 9887fb27f6126 ("Cygwin: New tool: profiler") Fixes: 087a3d76d7335 ("Cygwin: New tool: gmondump") Signed-off-by: Mark Geisert <mark@maxrnd.com>

- Updates to profiler and gmondump: error display mechanics, buffer sizing,
and output formatting.
Cygwin: rand(3): implement in terms of random(3) This makes rand(3) ISO C compliant and adds locking to avoid race conditions. Reported-by: Bruno Haible <bruno@clisp.org> Fixes: 8a0efa53e4491 ("import newlib-2000-02-17 snapshot") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

Cygwin: posix_fallocate: return ENODEV The fhandler method ftruncate returns either EISDIR if it has been called on directories, or EINVAL if called on files other than regular files. This matches what ftruncate(2) is supposed to return, but it doesn't match posix_fallocate(3), which is supposed to return ENODEV in both cases. To accomplish that, return ENODEV from fhandler_base::ftruncate() and convert it to EINVAL in ftruncate(2). In posix_fallocate(3), convert EISDIR to ENODEV.

Cygwin: open(2): reset sparseness on O_TRUNCated files open(2) implements O_TRUNC by just reducing the size of the file to 0, to make sure EAs stay available. Turns out, file sparseness is not removed this way either, so add code to do just that.

sparse files.
