This patch changes a lot of the code in ldb_dn.c, and also
removes and add a number of manipulation functions around.
The aim is to avoid validating a dn if not necessary as the
validation code is necessarily slow. This is mainly to speed up
internal operations where input is not user generated and so we
can assume the DNs need no validation. The code is designed to
keep the data as a string if possible.
The code is not yet 100% perfect, but pass all the tests so far.
A memleak is certainly present, I'll work on that next.
Simo.
(This used to be commit a580c871d3)
exposed.
Unfortunately this generates a large number of type punning
warnings. We'll have to find some magic to hide those.
(This used to be commit 254cbf09de)
appropriate.
Note that I also removed the error checks that were being done on the
result of talloc_steal(). They are pointless as talloc_steal() doesn't
have any failure modes that wouldn't cause a segv anyway, and they
tend to clutter the code
(This used to be commit c0d9e7d473)
Finally acknowledge that ldb is inherently async and does not have a dual personality anymore
Rename all ldb_async_XXX functions to ldb_XXX except for ldb_async_result, it is now ldb_reply
to reflect the real function of this structure.
Simo.
(This used to be commit 25fc735404)
r15944.
Hey idra I think a better rename would be to keep the LDB_REQ suffix
here to remain consistent with the other enums (e.g ldb_reply_type,
ldb_async_wait_type and ldb_async_state).
(This used to be commit d44ee8c43b)
the whole ldb structure.
Because the sequence number was a fn pointer on the main ldb context,
turn it into a full request (currently sync).

my previous patch added it for modules). This is the next step towards
LDB backends and modules as run-time loadable .so files.
(This used to be commit fb2f70de4f)
The module was just used to get to the ldb so it was meningless.
Also add LDB_WAIT_ONCE e relative code in ldb_ildap.c
(This used to be commit d5b467b7c1)
Currently only ldb_ildap is async, the plan
is to first make all backend support the async calls,
and then remove the sync functions from backends and
keep the only in the API.
Modules will need to be transformed along the way.

(This used to be commit 1e2c13b2d5)
to correctly support utf8 comparisons
add an ldb_attr_Casefold function for attribute names and use it
instead of casefold in the right places
(This used to be commit 3b4eb2413b)
Also add a way to provide utf8 compliant functions
by registering them with ldb_set_utf8_fns()
Next comes code to register samba internal utf8 functions.
Simo.
(This used to be commit ac9b8a41ff)
This patch changes the way lsb_search is called and the meaning of the returned integer.
The last argument of ldb_search is changed from struct ldb_message to struct ldb_result
which contains a pointer to a struct ldb_message list and a count of the number of messages.
The return is not the count of messages anymore but instead it is an ldb error value.
I tryed to keep the patch as tiny as possible bu as you can guess I had to change a good
amount of places. I also tried to double check all my changes being sure that the calling
functions would still behave as before. But this patch is big enough that I fear some bug
may have been introduced anyway even if it passes the test suite. So if you are currently
working on any file being touched please give it a deep look and blame me for any error.
Simo.
(This used to be commit 22c8c97e6f)
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 7e44f9153c)
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 c2bb2a36bd)
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 dba41164e0)
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 3fc676ac1d)
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 1da4ac2cdc)
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 4357a2db5e)
It is still far from being usable in samba4 but I want to commit
so that the work does not get lost by mistake.
This is also a good way to get comments if somebody is interested.
Sorry Derrell I ended up rewriting large parts of the code but I find
this style much more readable. Thanks for the hard work done. Your
work was a good reference for me.
ah the current code also shows some good numbers
sqlite3 generic test:
uid search took 0.05 seconds
real 0m12.492s
user 0m0.492s
sys 0m0.345s
with tdb we still get better numbers:
uid search took 0.46 seconds
real 0m0.892s
user 0m0.360s
sys 0m0.468s
but most of the time is spent in adding operations and I think
there's still a lot of space for improvement.
Simo.
(This used to be commit ace9990060)
in tests/test-sqlite3.sh (tests/test-generic.sh).
There are lots of optimizations still TBD, and some things are REALLY slow
right now (e.g. each add() operation takes 1/3 - 1/2 second) but it's ready for
interested parties to poke it and prod it and see how (un)reasonable it is.
Play away.
Still to be implemented or improved:
- tdb specials (@MODULES, @SUBCLASSES, etc.)
- all DNs are case-folded in their entirty right now (since doing otherwise
would require @ATTRIBUTES to be implemented)
- speed improvements and optimizations. I am quite confident that the
excessively slow add() operation can be much improved, and other areas
can be somewhat improved.
(This used to be commit 1dd8650055)
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 f648fdf187)
