/**
* This class implements EOF stack pooling including EOF stack synchronizing.
* It provides a special ERXEC.Factory in order to work without any changes in
existing
* applications. The number of EOObjectStoreCoordinators can be set with the
* system Property
<code>er.extensions.ERXObjectStoreCoordinatorPool.maxCoordinators</code>.
* Each Session will become one EOObjectStoreCoordinator and the method
* <code>newEditingContext</code> will always return an
<code>EOEditingContext</code>
* with the same <code>EOObjectStoreCoordinator</code> for the same
<code>WOSession</code>.
* This first release uses round-robin pooling, future versions might use
better algorithms
* to decide which <code>EOObjectStoreCoordinator</code> will be used for the
next new
* <code>WOSession</code>.<br>The code is tested in a heavy multithreaded
application
* and afawk no deadlock occures, neither in EOF nor directly in Java.

Hello there,
since I wrote an awk script to check whether my OSCs get unlocked properly,
I've bumped into one very strange thing in the locks.
First, my code is pretty straightforward (assuming we should lock OSC at all,
which is debatable -- based on http://terminalapp.net/dr-optimistic-locking/;
Chuck says well all right, though it should be sufficient to catch some
notifications instead):
===
EOEditingContext ec=auction.editingContext()
EOObjectStore osc=ec.rootObjectStore()
osc.lock()
try {
logln "$osc LOCKED FOR CU $sess.currentUser.login"
EOEditingContext tempec=ERXEC.newEditingContext()
... creating localInstanceIn as needed, updating them as
appropriate ...
tempec.saveChanges()
println "... saved successfully!"
} catch (exc) {
... reporting and logging error -- does not happen ...
} finally {
osc.unlock()
println "$osc UNLOCKED FOR CU $sess.currentUser.login"
}
===
and in one place in my logs, there is
===
26.1 14:06:03:
er.extensions.eof.ERXObjectStoreCoordinator@5d5e3b92[name=unnamed] LOCKED FOR
CU CEZProdej
... saved successfully!
26.1 14:06:03:
er.extensions.eof.ERXObjectStoreCoordinator@5d5e3b92[name=unnamed] LOCKED FOR
CU EPETas
... saved successfully!
er.extensions.eof.ERXObjectStoreCoordinator@5d5e3b92[name=unnamed] UNLOCKED FOR
CU CEZProdej
er.extensions.eof.ERXObjectStoreCoordinator@5d5e3b92[name=unnamed] UNLOCKED FOR
CU EPETas
===
What the darn?!? This should not be possible, or am I completely missing the
point of osc.lock()?!? :-O
In the vicinity, all the other logs looks all right, no exception not other
error reported.
As usual, I'll be pretty grateful for any insight,
OC
