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 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.
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
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
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
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.
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.
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
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.
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.
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
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
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()
I still think this URI syntax for a 'protocol' which has no network component
is stupid; it should just be
sqlite:local_file
or
sqlite:/full/path/to/file
but there is enough precedent to warrant the behavior that Simo wants that it
is not worth arguing.
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
