orbiter 1f300217f8 more protection for the cleanup thread
14 years ago
orbiter d13103a0a7 changed the way how the index cache is flushed: do not flush when a put was made because that could cause that many put calls synchronize for a long time when the dump or a merge is performed. Instead a watchdog thread is doing the dump and therefore puts cannot block any more which is good when a put happens during a search result preparation.

orbiter 1912d0cccc changed handling of RowSet element retrieval: until today all elements had been copied from the underlying byte[] arrays into a new Entry object that again had a copy of a portion of that byte[] in its own bye[]. There was an option to just refer to the underlying byte[] with a pointer but that was almost never used. This commit now changes an interface to the Row class where it is now necessary to tell if a copy is always required. Fortunately the copy is only needed in very rare cases. That means that this change should cause much less memory allocation; it is expected that this happens especially during search situations.

orbiter b666a929e7 fixed Semaphore handling in case of interruptions
14 years ago
orbiter 267290a821 removed the semaphores from the cache dump process because I believe some of the semaphores may be lost somewhere which then causes that the cache is never flushed and then the peer dies from a OOM. The re-introduced synchronization may not be the best solution but should ensure that the caches are flushed.
