signal hang
2013-12-10 04:47:13 +08:00
What changed:
-------------
Bug Fixes
---------
- Signals should no longer hang when they occur within a low-level
Windows DLL.
Fixes: http://cygwin.com/ml/cygwin/2013-12/threads.html#00151
* syscalls.cc (NT_TRANSACTIONAL_ERROR): Define. (stop_transaction): Take "trans" HANDLE by reference and set it to NULL after closing it. (unlink_nt): If NtOpenFile fails due to a transactional error, stop transaction and retry NtOpenFile. Simplify check for having to call stop_transaction. (rename): If NtOpenFile fails due to a transactional error, stop transaction and retry NtOpenFile in both affected cases. Simplify check for having to call stop_transaction and add comment from unlink_nt.

- If it turns out that transactions don't work during unlink(2) or rename(2),
despite the fact that the filesystem claims to handle them, stop transaction
and try again without.
