2010-09-27Change to using TDB_INCOMPATIBLE_HASH (the jenkins hash) on allJeremy Allison1-4/+4
TDB_CLEAR_IF_FIRST tdb's. For tdb's like gencache where we open without CLEAR_IF_FIRST and then with CLEAR_IF_FIRST if corrupt this is still safe to use as if opening an existing tdb the new hash will be ignored - it's only used on creating a new tdb not opening an old one. Jeremy.
2010-03-28s3: Use tdb_transaction_start_nonblock in gencache_stabilizeVolker Lendecke1-1/+10
This avoids the thundering herd problem when 5000 smbds exit simultaneously because the network went down.
2010-03-28Revert "s3: Optimize gencache for smbd exit"Volker Lendecke1-75/+14
This reverts commit 5ca63676dc59e83ffd9560fdcfa26063f267f283. That does not fully fix the problem, adding a tdb_transaction_start_nonblock to fix it.
2010-03-24s3: Optimize gencache for smbd exitVolker Lendecke1-14/+75
If thousands of smbds try to gencache_stabilize at the same time because the network died, all of them might be sitting in transaction_start. Don't do the stabilize transaction if nothing has changed in gencache_notrans.tdb. Volker
2009-12-07s3: let gencache_init() use tdb_check()Stefan Metzmacher1-0/+25
If the check fails we try to clear the tdb and start with an empty cache. metze
2009-11-02s3-gencache: restore gencache_get behavior with NULL args (with torture test).Günther Deschner1-4/+8
Without this, we panic in wins_srv_is_dead() and fail to start nmbd with wins support. Volker, please check. Guenther
2009-09-28s3:gencache: Add my copyrightVolker Lendecke1-0/+1
2009-09-23s3:gencache: Make gencache_del() return success for expired entriesVolker Lendecke1-4/+13
This fixes nasty error messages from "net cache flush"
2009-09-23s3:gencache: Remove some over-paranoid lockingVolker Lendecke1-6/+0
2009-09-23s3:gencache: Add a "was_expired" argument to gencache_get_data_blobVolker Lendecke1-10/+19
This is set to true if the routine returns failure due to an existing but expired entry.
2009-07-15Consolidate gencache also every 100 writes in a single processVolker Lendecke1-0/+14
2009-07-15Consolidate string and data_blob routines in gencacheVolker Lendecke1-138/+56
2009-07-15Make gencache more stableVolker Lendecke1-15/+268
This provides a compromise between stability and performance: gencache is a persistent database these days that for performance reasons can not use tdb transactions for all writes. This patch splits up gencache into gencache.tdb and gencache_notrans.tdb. gencache_notrans is used with CLEAR_IF_FIRST, writes to it don't use transactions. By default every 5 minutes and when a program exits, all entries from _notrans.tdb are transferred to gencache.tdb in one transaction.
2009-07-15Remove gencache_init/shutdownVolker Lendecke1-20/+1
gencache_get/set/del/iterate call gencache_init() internally anyway. And we've been very lazy calling gencache_shutdown, so this seems not really required.
2009-07-15Remove gencache_[un]lock_keyVolker Lendecke1-25/+0
2009-07-15TDB_CONTEXT -> "struct tdb_context"Volker Lendecke1-1/+1
2009-07-15Replace ASSERTs in gencache with "return false"Volker Lendecke1-12/+18
It's a bit strong to panic here I think.
2009-01-19simplify gencache_iterate a bit, fix nonempty blank linesVolker Lendecke1-86/+84
2008-07-11Revert "Return timed out entries from gencache_get if timeout param != NULL"Volker Lendecke1-15/+10
This reverts commit 2954b2be563149380e1fae7fe088b98d6cbd42e7. (This used to be commit 77ab2fb306a7ad59447a3e1591c2af03447e09c5)
2008-07-11Revert "Remove gencache_[un]lock_entry"Volker Lendecke1-0/+25
This reverts commit 7a5a575ffe5196caecedc93970a25abfbe6f8059. (This used to be commit 62e444dd50ae974c2ab9a553cdf7f188a8f2c538)
2008-07-03Remove gencache_[un]lock_entryVolker Lendecke1-25/+0
Günther agreed that it might be unnecessary in dsgetdcname_cache_store() :-) (This used to be commit 7a5a575ffe5196caecedc93970a25abfbe6f8059)
2008-07-03Return timed out entries from gencache_get if timeout param != NULLVolker Lendecke1-10/+15
net cache get was the only one interested in the timeout. That single caller can take care of the timeout itself then. With this API change idmap_cache.c can be converted to gencache. (This used to be commit 2954b2be563149380e1fae7fe088b98d6cbd42e7)

2007-10-10r17928: Implement the basic store for CLDAP sitenameJeremy Allison1-2/+0
support when looking up DC's. On every CLDAP call store the returned client sitename (if present, delete store if not) in gencache with infinate timeout. On AD DNS DC lookup, try looking for sitename DC's first, only try generic if sitename DNS lookup failed. I still haven't figured out yet how to ensure we fetch the sitename with a CLDAP query before doing the generic DC list lookup. This code is difficult to understand. I'll do some experiments and backtraces tomorrow to try and work out where to force a CLDAP site query first. Jeremy. (This used to be commit ab3f0c5b1e9c5fd192c5514cbe9451b938f9cd5d)
