...a Tcl extension. What happens is that fcntl with F_SETLK fails to get the lock, but reports success. If anyone is using the Tcl bindings you might need to be aware of this. Has anyone seen this with the Tcl (or any other) bindings? (Or indeed in any other context?) Thanks, Eric -- ms fnd in a lbry

...fail (and does for me) like so: > > terminate called after throwing an instance of 'Xapian::DatabaseLockError' > Aborted Got exactly that. Finally, it appears that it does work with Tcl 8.5 (actually a tclkit, but does not work with an 8.6 tclkit). Thanx, Eric -- ms fnd in a lbry

...nd it too has the problem. However with the very new Tcl 8.6.5rc2 it works! I still intend to try to find out what the problem was, but I can use the 8.5 tclkit for what I was doing when this all started, and then move to 8.6.5 when it becomes a real release. Thanx very much, Eric -- ms fnd in a lbry

...nce is definitely: open fork lock execl with the file showing up in lsof as 5w after the open, staying through the fork, changing to 5ww with the lock, and back to 5w with the execl. Which isn't supposed to happen according to any docs I can find. Thanx, Eric -- ms fnd in a lbry

...ases: * fork + exec being expected to need to preserve a file lock. * early creation of a notifier thread expected to be without undesirable side-effects Anyway, the answer is to use Tcl versions as above, or to use Xapian/kernel combinations where OFD locks are available.
