2012-07-18talloc: don't allow a talloc_pool inside a talloc_pool.Rusty Russell2-1/+9
We explicitly call free() on a pool which falls to zero, assuming it's not inside another pool (we crash). Check on creation and explicitly document this case. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-07-18talloc: use a struct for pool headers.Rusty Russell2-106/+90
This neatens the code a bit (we should do a similar thing for all the TALLOC_CHUNK macros). Two subtler changes: (1) As a result of the struct, we actually pack object_count into the talloc header on 32-bit platforms (since the header is 40 bytes, but needs to be 16-byte aligned). (2) I avoid VALGRIND_MAKE_MEM_UNDEFINED on memmove when we resize the only entry in a pool; that's done later anyway. With -O2 on my 11.04 Ubuntu 32-bit x86 laptop, the talloc_pool speed as measured by testsuite.c actually increases 10%. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-07-16pytdb: Check if the database is closed before we touch itAndrew Bartlett2-10/+85
If .close() has already been called, we have to play dead - the self->ctx is just not valid any more, as we have been shut down to allow some other part of Samba to open the tdb.

2012-07-16pytdb: Check for errors parsing strings into TDB_DATAAndrew Bartlett1-0/+16
The call to PyStringAsString() can raise an exception, and we want to return that rather than following a NULL pointer later. Andrew Bartlett

2012-07-09lib/ldb: Bump ldb release due to pyldb changesAndrew Bartlett3-1/+261
We strictly need these changes to pass make test, and the concat change is backwards incompatible, so we really want to use the right version. Andrew Bartlett Autobuild-User(master): Andrew Bartlett <abartlet@samba.org> Autobuild-Date(master): Mon Jul 9 04:34:06 CEST 2012 on sn-devel-104

This now concatonates Dn(ldb, "cn=config") + Dn(ldb, "dc=samba,dc=org") as "cn=config,dc=samba,dc=org" Andrew Bartlett

2012-06-30ccan: make it a grouping library.Rusty Russell1-0/+10
Andrew Bartlett pointed out that making CCAN a non-library will break the build in a different way in future: when two separate private libraries start using the same CCAN module, the symbol duplicate detection will fire (since private libaries don't use any symbol hiding). That doesn't happen yet, but it will surely happen eventually. So, for now at least, we build as a private library again. This unfortunately means the top-level build creates a libccan.so, which contains all the ccan modules whether you need them or not. Given the size of the library, I don't think this is a win. But it's simple.

2012-06-29ccan: we're subsystems, not a library.Rusty Russell4-24/+39
Don't expose a libccan.so; it would produce clashes if someone else does the same thing. Unfortunately, if we just change it from a SAMBA_LIBRARY to a SAMBA_SUBSYSTEM, it doesn't create a static library as we'd like, but links all the object files in. This means we get many duplicates (eg. everyone gets a copy of tally, even though only ntdb wants it). So, the solution is twofold: 1) Make the ccan modules separate. 2) Make the ccan modules SAMBA_SUBSYSTEMs not SAMBA_LIBRARYs so we don't build shared libraries which we can't share. 3) Make the places which uses ccan explicit.

2012-06-27s3-param: Rename loadparm_s3_context -> loadparm_s3_helpersAndrew Bartlett2-3/+3
This helps clarify the role of this structure and wrapper function. The purpose here is to provide helper functions to the lib/param loadparm_context that point back at the s3 lp_ functions. This allows a struct loadparm_context to be passed to any point in the code, and always refer to the correct loadparm system. If this has not been set, the variables loaded in the lib/param code will be returned. As requested by Michael Adam.

We use to handle UTCtime and generalized time the same way. The thing is that it's not the case, they are different in the way they are set (most of the time) with different format and also stored and return in different format too.

It's not portable. While we could use ccan/err, it seems overkill since we actually only use it in one test (I obviously cut & paste the #include).

2012-06-22tdb: make TDB_NOSYNC merely disable sync.Rusty Russell3-15/+20
(As suggested by Stefan Metzmacher, based on the change to ntdb.) Since commit ec96ea690edbe3398d690b4a953d487ca1773f1c, we handle the case where a process dies during a transaction commit. Unfortunately, TDB_NOSYNC means this no longer works, as it disables the recovery area as well as the actual msync/fsync. We should do everything except the syncs. This also means we can do a complete test with $TDB_NO_FSYNC set; just to get more complete coverage, we disable it explicitly for one test (where we override the actual sync calls anyway).

2012-06-22dbwrap: remove get_flags().Rusty Russell5-24/+0
The flags returned were TDB-specific: this was only used for detecting the endianness of obsolete databases (the conversion code was put in in 2003, with reference to Samba 2.3). It's easier to remove it than to translate the NTDB flags to TDB flags, and it's a really weird thing to ask for anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
