2011-06-20tdb2: tdb_parse_record() returns negative errors, not -1.Rusty Russell1-2/+2
Fixup callers to tdb_parse_record() to be compatible with tdb2. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb2: #ifdef out TDB_ERR_NOLOCK and TDB_ERR_LOCK_TIMEOUT.Rusty Russell1-1/+6
These don't exist in tdb2. The former is used in one weird place in tdb1, and the latter not at all. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb_compat: use tdb_errorstr_compat()Rusty Russell1-6/+6
Since TDB2 functions return the error directly, tdb_errorstr() taken an error code, not the tdb as it does in TDB1. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb_traverse/tdb_traverse_read: check returns for negative, not -1.Rusty Russell1-1/+1
TDB2 returns a negative error number on failure. This is compatible if we always check for < 0 instead of == -1. Also, there's no tdb_traverse_read in TDB2: we don't try to make traverse reliable any more, so there are no write locks anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb_transaction_cancel: ignore return value.Rusty Russell1-11/+5
TDB2 returns void here. tdb_transaction_cancel will *always* return with the transaction cancelled, but it will complain via the log function if a transaction wasn't in progress. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb_transaction_commit: check returns for 0, not -1.Rusty Russell1-4/+4
TDB2 returns a negative error number on failure. This is compatible if we always check for != 0 instead of == -1. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb_delete: check returns for 0, not -1.Rusty Russell1-3/+3
TDB2 returns a negative error number on failure. This is compatible if we always check for != 0 instead of == -1. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-06-20tdb_fetch_compat: use instead of tdb_fetch.Rusty Russell1-1/+1
This is a noop for tdb1. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-04-19gencache: don't use CLEAR_IF_FIRST as fallback.Rusty Russell1-7/+3
CLEAR_IF_FIRST only works if *all* openers use that flag. So just truncate the file: it's racy, but that's what we're doing anyway. We'd really need a TDB_OPENCHECK_OR_CLEAR flag to do this properly (or in TDB2, a open hook at the right point). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-11-28s3: Add gencache_iterate_blobsVolker Lendecke1-57/+87
2010-11-28s3: Convert gencache_get_data_blob to gencache_parseVolker Lendecke1-59/+38
2010-11-28s3: Add gencache_parseVolker Lendecke1-0/+59
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)

2008-02-25Fix some warningsVolker Lendecke1-6/+6
warning: ignoring return value of 'asprintf', declared with attribute warn_unused_result (This used to be commit ad37b7b0aee265a3e4d8b7552610f4b9a105434d)
2007-12-28don't store cache_readonly in gencacheVolker Lendecke1-15/+0
tdb won't allow us to write anyway (This used to be commit 069cd6d63a61065be7926230235e198c456d38ae)
2007-10-18RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison1-11/+11
bugs in various places whilst doing this (places that assumed BOOL == int). I also need to fix the Samba4 pidl generation (next checkin). Jeremy. (This used to be commit f35a266b3cbb3e5fa6a86be60f34fe340a3ca71f)
2007-10-10r24733: Add support for storing DATA_BLOBs in gencache.tdb (including ↵Günther Deschner1-0/+157
torturetest). Mimir, please have a look. DATA_BLOBs will now just show up as "DATA_BLOB" values with "net cache list". Guenther (This used to be commit b8ad546d041a2a8cc85c7db8eba4d2d3b97df1a8)
2007-10-10r23784: use the GPLv3 boilerplate as recommended by the FSF and the license textAndrew Tridgell1-2/+1

2007-10-10r21976: make use of tdb_*_bystring() and string_term_tdb_data() in lib/Stefan Metzmacher1-17/+9
to avoid creating the TDB_DATA struct from strings "by hand" metze (This used to be commit c22b86595a502eb48c9d0038faee8a9ee41b8438)

2007-10-10r19414: gencache is getting really important now, make sure that lp_lockdirGünther Deschner1-1/+1
always exists so that the gencache.tdb can get created there. Guenther (This used to be commit e5ed286125d1f4b8b28bf143f987102071fd0de2)
