16 hoursCygwin: console: Fix for GNU screen/tmux in ConEmuHEADgithub/mastergithub/mainmastermainTakashi Yano1-1/+18
If the master process of GNU screen or tmux is started in ConEmu and ConEmu is closed, reattaching to the GNU screen/tmux in another console will not work correctly. This is because the ConEmu master process was already closed even though some console APIs are hooked by ConEmuHk64.dll to communicate with ConEmu master process. With this patch, to make them unhooked, DllMain() of ConEmuHk64.dll is called with DLL_PROCESS_DETACH. Fixes: 3721a756b0d8 ("Cygwin: console: Make the console accessible from other terminals.")

16 hoursCygwin: console: Fix race issue on allocating console simultaneously.Takashi Yano6-56/+57
Previously, if two or more processes request to allocate a console at the same time, the same device number could be accidentally allocated. This patch fixes the issue by creating a named mutex (input_mutex) and checking if GetLastError() is ERROR_ALREADY_EXIST or not to ensure the unit number will be allocated in an atomic way. Thanks to this, EnumWindow() is not necessary anymore to scan console units. This also makes minor device numbers unique and console devices visible across sessions. This disallows duplicated device number for different sessions, so the MAX_CONS_DEV has been increased from 64 to 128. Additionally, the console allocation and scanning will be faster as a side effect of eliminating EnumWindows().

The commit baf2764dca43 has a serious bug that shared_info_state is common for all console devices despite it should be individual for each console device. This patch fixes that.

After the commit c77a5689f7bd, tmux can not run on the console. This patch replaces the countermeasure for the race issue between console setup and close with another mechanism using a mutex.

6 daysCygwin: console: Fix conflict on shared names between sessions.Takashi Yano2-4/+14
Previously, shared names in the console were created using get_minor(). However, get_minor() was not unique to the console across sessions. This is because EnumWindows(), which is used to look for console windows, cannot enumerate windows across sessions. This causes conflict on the shared names between sessions (e.g. sessions of different users, different services, a service and a user session, etc.). With this patch, GetConsoleWindow() is used instead of get_minor(). GetConsoleWindow() has been used for the name of shared memory, which should be unique to each console.

8 daysCygwin: pty: Avoid client deadlock when pty master stops to read.Takashi Yano2-3/+26
Previsouly, the following commands hangs: mintty -e timeout 1 dash -c 'yes aaaaaaaaaaaaaaaaaaaaaaaaa | cat' The mechanism is as follows. When the child process (timeout) is terminated, mintty seems to stop reading pty master even if yes or cat still alive. If the the pipe used to transfer output from pty slave to pty master is full due to lack of master reader, WriteFile() to the pipe is blocked. WriteFile() cannot be canceled by cygwin signal, therefore, pty slave hangs. This patch avoids hanging by checking pipe space before calling WriteFile() and prevents writing data more than space.

2024-05-22arc: libc, libgloss: Remove .file directive from .S filesYuriy Kolerov2-5/+2
Assembler for ARCv2 always extends the name provided by .file directive to an absolute form. On ARCv3 targets .file directive forces assembler to put a provided string to DW_AT_name field as is without extending to an absolute path. Then GDB cannot find source files because of it. The best way to fix this issue is just delete lines with .file directive in .S files and let the compiler to decide what DW_AT_name must contain. Particularly, the compiler fills this filed by an absolute path to a .S file because only absolute paths are used in toolchain's build process. Signed-off-by: Yuriy Kolerov <kolerov93@gmail.com>

Commit 80f722e97cf7 ("Cygwin: opendir(3): move ENOTDIR check into main function") introduced a bug in fhandler_virtual handling. While the assertion that path_conv::check() already calls exists() and sets FILE_ATTRIBUTE_DIRECTORY accordingly, the exists() function is called on a fhandler_virtual object created for just this code snippet. The side effect of this is that the fileid member in the calling fhandler_virtual object is not set after path_conv::check(). Move the fhandler_virtual::fileid member to path_conv::_virt_fileid and create matching path_conv::virt_fileid() and fhandler_virtual::fileid() methods. Let path_conv::check() propagate the fileid set in the local fhandler_virtual::exists() call to its own _virt_fileid. Use new fhandler_virtual::fileid() method throughout.
