[PATCH v7 4/4] Cygwin: pty: Allow multiple apps to enable pseudo console simultaneously.

- After commit bb428520, there has been the disadvantage: 7) Pseudo console cannot be activated if it is already activated for another process on same pty. This patch clears this disadvantage. --- winsup/cygwin/fhandler.h | 7 +- winsup/cygwin/fhandler_tty.cc | 344

[PATCH v7 3/4] Cygwin: pty: Make apps using console APIs be able to debug with gdb.

- After commit bb428520, there has been the disadvantage: 2) The apps which use console API cannot be debugged with gdb. This is because pseudo console is not activated since gdb uses CreateProcess() rather than exec(). Even with this limitation, attaching gdb to native app, in

[PATCH v7 1/4] Cygwin: pty: Inherit typeahead data between two input pipes.

- PTY has a problem that the key input, which is typed during windows native app is running, disappears when it returns to shell. This is beacuse pty has two input pipes, one is for cygwin apps and the other one is for native windows apps. The key input during windows native program is

[PATCH v7 0/4] Improve pseudo console support.

The new implementation of pseudo console support by commit bb428520 provides the important advantages, while there also has been several disadvantages compared to the previous implementation. These patches overturn some of them. The disadvantage: 1) The cygwin program which calls console API

[PATCH] Cygwin: getdtablesize: always return OPEN_MAX_MAX

According to the Linux man page for getdtablesize(3), the latter is supposed to return "the maximum number of files a process can have open, one more than the largest possible value for a file descriptor." The constant OPEN_MAX_MAX is the only limit enforced by Cygwin, so we now return that.

[PATCH v2] Cygwin: fchmodat: add limited support for AT_SYMLINK_NOFOLLOW

Allow fchmodat with the AT_SYMLINK_NOFOLLOW flag to succeed on non-symlinks. Previously it always failed, as it does on Linux. But POSIX permits it to succeed on non-symlinks even if it fails on symlinks. The reason for following POSIX rather than Linux is to make gnulib report that fchmodat
