Takashi Yano via Cygwin-patches 5755870f7c Cygwin: pty: Reduce buffer size in get_console_process_id().
- The buffer used in get_console_process_id(), introduced by commit
  72770148, is too large and ERROR_NOT_ENOUGH_MEMORY occurs in Win7.
  Therefore, the buffer size has been reduced.

Takashi Yano via Cygwin-patches a776a0ce26 Cygwin: pty: Set input_available_event only for cygwin pipe.
- cat exits immediately in the following senario.
    1) Execute env CYGWIN=disable_pcon script
    2) Execute cmd.exe
    3) Execute cat in cmd.exe.
  This is caused by setting input_available_event for the pipe for
  non-cygwin app. This patch fixes the issue.

Takashi Yano via Cygwin-patches 25ce7a6245 Cygwin: pty: Make master thread functions be static.
- The functions pty_master_thread() and pty_master_fwd_thread()
  should be static (i.e. should not access class member) because
  the instance is deleted if the master is dup()'ed and the first
  master is closed. In this case, because the dup()'ed instance
  still exists, these master threads are also still alive even
  though the instance has been deleted. As a result, accesing
  class members in these functions causes accessi violation.

Takashi Yano via Cygwin-patches 72770148ad Cygwin: pty: Prevent pty from changing code page of parent console.
- After commit 232fde0e, pty changes console code page when the first
  non-cygwin app is executed. If pty is started in real console device,
  pty changes the code page of root console. This causes very annoying
  result because changing code page changes the font of command prompt
  if console is in legacy mode. This patch avoids this by creating a
  new invisible console for the first pty started in console device.

- The function close_pseudoconsole() should be static so that it

  instance has been deleted. That is, there is a problem with the
  current code. This patch fixes the issue.

Takashi Yano via Cygwin-patches 974e6d76d8 Cygwin: console: Revise the code to switch xterm mode.
- If application changes the console mode, mode management introduced
  by commit 10d8c278 will be corrupted. For example, stdout of jansi
  v2.0.1 or later is piped to less, jansi resets the xterm mode flag
  ENABLE_VIRTUAL_TERMINA_PROCESSING when jansi is terminated. This
  causes garbled output in less because less needs this flag enabled.
  This patch fixes the issue.

Fabian Schriever cf1ef2dc5b Fix error in powf for x close to 1 and large y
This patch fixes the error found by Paul Zimmermann (see
https://homepages.loria.fr/PZimmermann/papers/#accuracy) regarding x
close to 1 and rather large y (specifically he found the case
powf(0x1.ffffeep-1,-0x1.000002p+27) which returns +Inf instead of the
correct value). We found 2 more values for x which show the same faulty
behaviour, and all 3 are fixed with this patch. We have tested all
combinations for x in [+1.fffdfp-1, +1.00020p+0] and y in
[-1.000007p+27, -1.000002p+27] and [1.000002p+27,1.000007p+27].

Mark Geisert 9e573ba50f Cygwin: Allow to set SO_PEERCRED zero (v2)
The existing code errors as EINVAL any attempt to set a value for
SO_PEERCRED via setsockopt() on an AF_UNIX/AF_LOCAL socket.  But to
enable the workaround set_no_getpeereid behavior for Python one has
to be able to set SO_PEERCRED to zero.  Ergo, this patch.  Python has
no way to specify a NULL pointer for 'optval'.

This v2 of patch allows the original working (i.e., allow NULL,0 for
optval,optlen to mean turn off SO_PEERCRED) in addition to the new
working described above.  The sense of the 'if' stmt is reversed for
readability.

Corinna Vinschen aec6479820 Cygwin: add flag to indicate reparse points unknown to WinAPI
https://cygwin.com/pipermail/cygwin/2020-December/246938.html
reports a problem where, when adding a Cygwin default symlink
to $PATH since Cygwin 3.1.5, $PATH handling appears to be broken.

3.1.5 switched to WSL symlinks as Cygwin default symlinks.

A piece of code in path handling skips resolving reparse points
if they are the last component in the path.  Thus a reparse point
in $PATH is not resolved but converted to Windows path syntax
verbatim.

If you do this with a WSL symlink, certain WinAPI functions fail.
The underlying $PATH handling fails to recognize the reparse
point in $PATH and returns with STATUS_IO_REPARSE_TAG_NOT_HANDLED.
As a result, the calling WinAPI function fails, most prominently
so CreateProcess.

Fix this problem by adding a PATH_REP_NOAPI bit to path_types
and a matching method path_conv::is_winapi_reparse_point().

Right now this flag is set for WSL symlinks and Cygwin AF_UNIX
sockets (new type implemented as reparse points).

The aforementioned code skipping repare point path resolution calls
is_winapi_reparse_point() rather than is_known_reparse_point(),
so now path resolution is only skipped for reparse points known
to WinAPI.
