src/xpdev/filewrap.c
Log Message:
Get rid of the fcntl() usage in sopen()

You can't lock a file on a Samba share via both fcntl() and flock() (the interact/collide).

This code was in a !BSD block which means they guy that wrote/committed
it wasn't using it either.

Modified Files:
src/xpdev/filewrap.c
Log Message:
Log a build warning if building for Linux without OFD lock support

OFD locks are needed on Linux for appropriate multi-threaded shared file
access (using fcntl record locks to prevent corruption), so log a warning if building for Linux without that support.

lock() now mimics DOS/Windows again: the result lock is an "all access" lock regardless of what mode the file was open in. I'm not sure why this change was made (commit 11b73134563ce26), but I don't think it was necessary or appropriate (though I can't think of any immediate negative effects). At minimum it makes the code a little more understandable and eliminates an
extra call to fcntl().

Revert the lock() change in commit 043feff8

So this change is needed or else fcntl() will fail with errno=BADF if trying
to write-lock a file that was opened read-only. Oh well. Added a comment explaining the rationale.

Modified Files:
src/xpdev/filewrap.c
Log Message:
Don't use flock() in sopen() since it ends up using non-OFD fcntl() locks

When OFD locks are available, that's what we should be using.
Otherwise, we suffer the horrible behavior of POSIX file/region locks and
a subsequent open/close of the file releases any/all locks on it.

This is currently in an !BSD block, which appears to include macOS, but
macOS *does* support OFD locks, so I'll be fixing that here shortly.
