What kind of locking does sqlite use on Cygwin: [ ] POSIX fcntl locks [ ] BSD flock locks [ ] Old POSIX lockf locks? Here's a proposal: - Only add optional mandatory locking to fcntl and flock locks, not for lockf locks. - Add a flag F_MDLCK which can be or'ed to struct flock's l_type. - Add a flag LOCK_MD which can be or'ed to the 2nd parameter to flock(2). - Using these flags, I'll resurrect the old pre-Cygwin 1.7 locking code which does NOT support F_GETLK. I will try, but I can also not guarantee that a blocking, mandatory lock call will be interruptible by signals. - For anything else, http://cygwin.com/acronyms/#PTC Does that sound ok?
