2012-10-04tdb: add tdb_rescue()Rusty Russell1-0/+22
This allows for an emergency best-effort dump. It's a little better than strings(1). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2011-03-15tdb: use system include style for system headersAndrew Tridgell1-1/+1
2011-01-19tdb: Added doxygen documentation.Andreas Schneider1-25/+693
Autobuild-User: Andreas Schneider <asn@samba.org> Autobuild-Date: Wed Jan 19 11:26:34 CET 2011 on sn-devel-104

2010-10-23tdb: Revert re-addition of tdb_set_logging_function.Jelmer Vernooij1-1/+0
I accidentally committed this patch which we carry in the Debian packages. Autobuild-User: Jelmer Vernooij <jelmer@samba.org> Autobuild-Date: Sat Oct 23 18:37:16 UTC 2010 on sn-devel-104
2010-10-21Lowercase socket_wrapper name.Jelmer Vernooij1-0/+1
Avoid linking against socket_wrapper outside of developer mode. Autobuild-User: Jelmer Vernooij <jelmer@samba.org> Autobuild-Date: Thu Oct 21 20:26:11 UTC 2010 on sn-devel-104
2010-10-21tdb: Set _PUBLIC_ in C file rather than header files (Debian bug 600898)Jelmer Vernooij1-62/+62

2010-09-27tdb: TDB_INCOMPATIBLE_HASH, to allow safe changing of default hash.Rusty Russell1-0/+1
This flag to tdb_open/tdb_open_ex effects creation of a new database: 1) Uses the Jenkins lookup3 hash instead of the old gdbm hash if none is specified, 2) Places a non-zero field in header->rwlocks, so older versions of TDB will refuse to open it. This means that the caller (ie Samba) can set this flag to safely change the hash function. Versions of TDB from this one on will either use the correct hash or refuse to open (if a different hash is specified). Older TDB versions will see the nonzero rwlocks field and refuse to open it under any conditions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-09-27tdb: add Bob Jenkins lookup3 hash as helper hash.Rusty Russell1-0/+1
This is a better hash than the default: shipping it with tdb makes it easy for callers to use it as the hash by passing it to tdb_open_ex(). This version taken from CCAN and modified, which took it from http://www.burtleburtle.net/bob/c/lookup3.c. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-04-20tdb: update tdb ABI to use hide_symbols=TrueAndrew Tridgell1-65/+64
We now use -fvisibilty=hidden to hide symbols from outside the tdb shared library. This also moved tdb_transaction_recover() into the tdb_private.h header, as it should never have been a public API. For that reason we are changing the version number. We're only doing a minor version increment as it is extremely unlikely that anyone was actually using tdb_transaction_recover() as its locking requirements were rather unusual.

2010-03-26tdb: Add a non-blocking version of tdb_transaction_startVolker Lendecke1-0/+1
2009-12-21tdb: Also build and install tdb manpages from standalone tdb.Jelmer Vernooij1-1/+1
2009-11-20tdb: add TDB_DISALLOW_NESTING and make TDB_ALLOW_NESTING the default behaviorStefan Metzmacher1-0/+1
We need to keep TDB_ALLOW_NESTING as default behavior, so that existing code continues to work. However we may change the default together with a major version number change in future. metze
2009-11-20New attempt at TDB transaction nesting allow/disallow.Ronnie Sahlberg1-1/+3
Make the default be that transaction is not allowed and any attempt to create a nested transaction will fail with TDB_ERR_NESTING. If an application can cope with transaction nesting and the implicit semantics of tdb_transaction_commit(), it can enable transaction nesting by using the TDB_ALLOW_NESTING flag. (cherry picked from ctdb commit 3e49e41c21eb8c53084aa8cc7fd3557bdd8eb7b6) Signed-off-by: Stefan Metzmacher <metze@samba.org>
2009-10-22lib/tdb: add tdb_check()Rusty Russell1-0/+3
ctdb wants a quick way to detect corrupt tdbs; particularly, tdbs with loops in their hash chains. tdb_check() provides this. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-10-22lib/tdb: wean off TDB_ERRCODE.Rusty Russell1-2/+0
It was a regrettable hack which I used to reduce line count in tdb; in fact it caused confusion as can be seen in this patch. In particular, ecode now needs to be set before TDB_LOG anyway, and having it exposed in the header is useless (the struct tdb_context isn't defined, so it's doubly useless). Also, we should never set errno, as io.c was doing. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-03-31Add tdb_transaction_prepare_commit()Howard Chu1-0/+1
Using tdb_transaction_prepare_commit() gives us 2-phase commits. This allows us to safely commit across multiple tdb databases at once, with reasonable transaction semantics Signed-off-by: tridge@samba.org
2008-12-16imported the tdb_repack() code from CTDBAndrew Tridgell1-1/+4
The tdb_repack() function repacks a TDB so that it has a single freelist entry. The file doesn't shrink, but it does remove all freelist fragmentation. This code originated in the CTDB vacuuming code, but will now be used in ldb to cope with fragmentation from re-indexing
2008-09-19Add shared-build target to tdb.Simo Sorce1-0/+1
Useful to build multiple standalone libraries that depend on each other without having to install them to the final install dir during the build.
