a search() function, instead each module now only implements the
bytree method, and the expression based search is handled generically
by the modules code. This makes for more consistency and less code
duplication.
fixed the tdb backend to handle BASE searches much more
efficiently. They now always only lookup one record, regardless of the
search expression
(This used to be commit 7e44f9153c5578624e2fca04cdc0a00af0fd9eb4)
do not autostart transactions on ldb operations if a transaction is already in place
test transactions on winsdb
all my tests passes so far
tridge please confirm this is ok for you
(This used to be commit c2bb2a36bdbe0ec7519697a9a9ba7526a0defac2)
locking code in the ldb_tdb backend, except for a single read lock
during searches to ensure searches don't cross transaction boundaries
The tdb transactions code would map these extra locks to noops anyway
(as locking makes no sense inside a transaction), but the work in
setting up the locking keys still costs something, and it makes the
code needlessly complex
(This used to be commit 1b8d368a6771360fb0626127c02b3eb95f3eae59)
transactions are synchronous or not on the command line.
add LDB_FLG_NOSYNC flag to ldb_connect() so we can make our temporary
ldb databases non-synchronous
(This used to be commit dba41164e0c52f1e4351bd9057b16661cee3a822)
samba-technical posting for more details on the transactions design.
This also adds a number of command line arguments to tdbtorture,
making it more flexible, and fixes some lock deadlock conditions in
the tdbtorture code.
(This used to be commit 06bd8abba942ec9f1e23f5c5d546cbb71ca3a701)
changed the prioivate modules API
error string are now not spread over all
modules but are kept in a single place.
This allows a better control of memory
and error reporting.
(This used to be commit 3fc676ac1d6f59d08bedbbd9377986154cf84ce4)
private ldb API
ldb_sqlite3 is already working with this model and ldb_tdb will do
as soon as tridge finishes the tdb transaction code.
currently the transactions are always implicit and wrap any single
ldb API call except searching, the transaction functions are
currently not made public on purpose.
Simo.
(This used to be commit 1da4ac2cdcb7e54076f85242a93784260dced918)
just involves splitting up the core tdb.c code into separate files on
logical boundaries, but there are some minor functional changes as well:
- move the 'struct tdb_context' into tdb_private.h, hiding it from
users. This was done to allow the structure to change without
breaking code that uses tdb.
- added accessor functions tdb_fd(), tdb_name(), and tdb_log_fn() to
access the elements of struct tdb_context that were used by
external code but are no longer visible
- simplied tdb_append() to use tdb_fetch()/tdb_store(), which is just
as good due to the way tdb locks work
- changed some of the types (such as tdb_off to tdb_off_t) to make
syntax highlighting work better
- removed the old optional spinlock code. It was a bad idea.
- fixed a bug in tdb_reopen_all() that caused tdbtorture to sometimes
fail or report nasty looking errors. This is the only real bug
fixed in this commit. Jeremy/Jerry, you might like to pickup this
change for Samba3, as that could definately affect smbd in
Samba3.
The aim of all of these changes is to make the tdb
transactions/journaling code I am working on easier to write. I
started to write it on top of the existing tdb.c code and it got very
messy. Splitting up the code makes it much easier to follow.
There are more cleanups we could do in tdb, such as using uint32_t
instead of u32 (suggested by metze). I'll leave those for another day.
(This used to be commit 4673cdd0d261614e707b72a7a348bb0e7dbb2482)
I must say that writing a new module is a very good way
to find lot of subtle bugs laying in the code
We need more tests!
commit oLschema2ldif.c to keep it safe from data losses (rm -fr :-)
update test generic to reflect the fix made on comparsion functions
(This used to be commit 4357a2db5eadb15519ed93b957b2bad25ebf2a7d)
avoid the horrors of posix locking, but it was preventing us having an
ldb open twice with different options. Now each ldb open of the same
file shares the same underlying tdb, but uses a different ldb
structure
(This used to be commit 4e090c66dfa1d2764e4693578d3845be3b8893f6)
better pares filters
Approx is currently only a stub need to dig more info to
understand what it really means and how it works exactly
(This used to be commit a9e8cd0bad27ed2b3c6a12302e787ba3c9a70a3c)
S390. This is an attempt to avoid the panic we're seeing in the
automatic builds.
The main fixes are:
- assumptions that sizeof(size_t) == sizeof(int), mostly in printf formats
- use of NULL format statements to perform dn searches.
- assumption that sizeof() returns an int
(This used to be commit a58ea6b3854973b694d2b1e22323ed7eb00e3a3f)
This code applies correct ldap standard wildcard matching code
removes WILDCARD matching from tdb @ATTRIBUTES, that's now handled independently
adds some more tests for wildcard matching
fixes dn comparison code in ldb_match
(This used to be commit 4eb5863042011988d85092d7dde3d809aa15bd59)
- we do not support multpiple attribute components anymore, makes code a lot easier
they will be readded later if we found out they are really used, so far my tests
show w2k3 do not handle them as well
- fix escaping issues, move component value to be in an ldb_val structure
still need to handle binary values case
- make cononicalize functions leak less memory by giving a specific memory context
- fix tests scripts so that test-ldap can start
- make test not delete databases on completion so that I can inspect them
(This used to be commit 624a73148d125690ce18515f19231d26df207738)
- added support for recognising the S- form of objectsid in search
expressions. I thought this could be done with just a comparison
modified comparison function, but it turns out it also needs a
canonicalisation function so that indexing can work
(This used to be commit 7d2bee2c5619f284375ecbed14371c5e8639ed1c)
- moved the knowledge of attribute types out of ldb_tdb and into the
generic ldb code. This allows the ldb_match() message match logic
to be generic, so it can be used by other backend
- added the generic ability to load attribute handlers, for
canonicalisation, compare, ldif read and ldif write. In the future
this will be used by the schema module to allow us to correctly
obey the attributetype schema elements
- added attribute handlers for some of the core ldap attribute types,
Integer, DirectoryString, DN, ObjectClass etc
- added automatic registration of attribute handlers for well-known
attribute names 'cn', 'dc', 'dn', 'ou' and 'objectClass'
- converted the objectSid special handlers for Samba to the new system
- added more correct handling of indexing in tdb backend based on the
attribute canonicalisation function
- added generic support for subclasses, moving it out of the tdb
backend. This will be used in future by the schema module
- fixed several bugs in the dn_explode code. It still needs more
work, but doesn't corrupt ldb dbs any more.
(This used to be commit 944c5844ab441b96d8e5d7b2d151982139d1fab9)
bug was being silently ignored with the tdb backend because of this
bug. A case where the ldap backend was right, and the tdb backend was
wrong!
(This used to be commit ddb26db763c314049043d80d27113226c0f2e656)
cmdline credentials code (which will be done soon)
- added a ldb_init() call, and changed ldb_connect() to take a ldb
context. This allows for much better error handling in
ldb_connect(), and also made the popt conversion easier
- fixed up all the existing backends with the new syntax
- improved error handling in *_connect()
- fixed a crash bug in the new case_fold_required() code
- ensured that ltdb_rename() and all ltdb_search() paths get the read lock
- added a ldb_oom() macro to make it easier to report out of memory
situations in ldb code
(This used to be commit f648fdf187669d6d87d01dd4e786b03cd420f220)
Old way was ugly and had a bug, you couldn't add an attribute named
dn or distinguishedName and search for it, tdb would change that search in a dn search.
This makes it also possible to search by dn against an ldap server as the old method was
not supported by ldap syntaxes.

(This used to be commit a614466dec2484a0d39bdfae53da822cfcf80926)
using to perform such things as bitop tests on integers.
So far I have only added support for the 1.2.840.113556.1.4.803 and
1.2.840.113556.1.4.804 rules, which are for bitwise and/or
(This used to be commit 5f773b065f1db959e59c02de68bcf30cef1a6c2c)
instead of a search expression. This allows our ldap server to pass
its ASN.1 parsed search expressions straight to ldb, instead of going
via strings.
- updated all the ldb modules code to handle the new interface
- got rid of the separate ldb_parse.h now that the ldb_parse
structures are exposed externally
- moved to C99 structure initialisation in ldb
- switched ldap server to using ldb_search_bytree()
(This used to be commit 96620ab2ee5d440bbbc51c1bc0cad9977770f897)
called from multiple backends. (ldb_sqlite3 needs it too.) Added parameter
for a callback function that determines whether an attribute needs case
folding.
- begin to prepare for sqlite3 in build process
- work-in-progress updates, on ldb_sqlite3
(This used to be commit a80bced0b96ffb655559a43cf7f4d7a34deb5a7d)
this object properties are now used as multivalue attributes
now all values inserted are checked against a "valid values table"
eg:
this form is now accepted:
dn: @ATTRIBUTES
uid: CASE_INSENSITIVE
uid: WILDCARD
this form is now rejected:
dn: @ATTRIBUTES
uid: CASE_INSENSITIVE WILDCARD
please update your .ldb files if you make use of @ATTRIBUTES
(sam.ldb heavily uses it)
the code passes all make test tests for both tdb and ldap, it also
passes the new test to check for wrong @ATTRIBUTES attribute values
Simo.
(This used to be commit 1295b891a26c2cb2c34540f90ded83390cf87da2)
example:
*: CASE_INSENSITIVE
by placing it in the @ATTRIBUTES object you make all the matching be case insensitive
to make an excepion to the general rule now you just need to create an entry like:
name: CASE_SENSITIVE
the key CASE_SENSITIVE currently does not exist but has the effect of making the code
ignore the wildcard default flag and being ldb case sensitive by default it let the
"name" attribute be case sensitive again
Tridge, can you look at this commit?
Should we introduce a CASE_SENSITVE/BINARY flag and handle it in the code ?
Simo.
(This used to be commit 5f10707e8ac36db03f3aa3e1ee1c40a9d9da2016)
that ldb_search() sees a single consistent view of the database (by
blocking writes during a ldb_search)
(This used to be commit 917f2a8a073fd501f0626bea4f9deb91b95fdc90)
changes:
- ldb_wrap disappears from code and become a private structure of db_wrap.c
thanks to our move to talloc in ldb code, we do not need to expose it anymore
- removal of ldb_close() function form the code
thanks to our move to talloc in ldb code, we do not need it anymore
use talloc_free() to close and free an ldb database
- some minor updates to ldb modules code to cope with the change and fix some
bugs I found out during the process
(This used to be commit d58be9e74b786a11a57e89df36081d55730dfe0a)
the case sensitive/insensitive flags on sections of a dn. So if a dn
is made up of 4 attributes, and 2 of those are case insensitive and 2
are case sensitive, then all the attribute names are uppercases, but
only the values of the case insensitive attributes are uppercased when
forming the tdb key.
- added code to canonicalise the dn, removing leading and trailing
spaces from attribute names and values
- when the @ATTRIBUTES record changes, fix the dn keys of any records that should now have new
dn keys due to changes in the case sensitivity of the record
I really did this to allow me to make the WINS database properly case
insensitive, but it is also the correct general fix for ldb, as it
matches the LDAP specification (and w2k LDAP server behaviour)
(This used to be commit 0f034dc5636d182a1d9207ad662b3fc8df7ca3e4)
less likely that anyone will use pstring for new code
- got rid of winbind_client.h from includes.h. This one triggered a
huge change, as winbind_client.h was including system/filesys.h and
defining the old uint32 and uint16 types, as well as its own
pstring and fstring.
(This used to be commit 9db6c79e902ec538108d6b7d3324039aabe1704f)
- removed the u32 hack in events.c as I think this was only needed as
tdb.h defines u32. Metze, can you check that this hack is indeed no
longer needed on your suse system?
(This used to be commit 6f79432fe656164d4770dbce114a30dda5e7bf9a)
samba-technical posting), this is an interim solution that makes us
work pretty much like w2k3 does.
(This used to be commit 789325145651f2f6fc8716aa4bced83a2eb31994)
this helps standalone building of ldb
renew the schema module
split code into functions to improve readability and code reuse
add and modify works correctly but we need a proper testsuite
Simo
(This used to be commit a681ae365ff1b5a2771b42ebd90336651ce1e513)
