It seems to me that this synchronization also
affects other requests (not only Page). We have a page with images taken from
database. The images appear one by one instead of "simultaneous"...

not
unless all page targets return the same mutex instance :)
the point is
that only a single page is processed at a time because of pagemap, etc.
although i dont really know if the pagemap is affected all that much in
2.0.
but even then, lets say i double click a link really fast, i get
two different instances of pagetarget that are going to do processing on the
same page instance, so once again both of those page targets have to return
the same mutex instance. dont know how we are going to do that or if it will
be simpler/better then locking session.
the thing about the db locking
up is that it should have some sort of a timeout that throws an error, and the
sync block should then be broken. that doesnt happen? sounds like more of a
fault in your app? maybe we should build a timeout for our sync block.

Hi,
we
have a problem with session locking. Sometimes, the underlying
database
just hangs and the response is not processed properly. The
problem is
that HttpSession remains locked.
Wouldn't it be possible to replace
the current locking mechanism
( synchronized(lock) { doEverything()
} )
with something that would behave more like a
mutex?
e.g.
Mutext mutex =
getRequestTarget().getMutex();
mutex.lock();
processRequest();
mutex.unlock
();
and the code running the operation could look
like
RequestCycle().get().getReqeustTarget().getMutex().unlock();
doMySloooowOperation();
RequestCycle().get().getReqeustTarget().getMutex().lock();
