to link in. There's still a whole lot of random other junk (dcerpc, gensec,
ndr stuff, lp_foo - what a mess).
(This used to be commit b78cf1270bd7eda1aa84d238136a83e64ff3c088)
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)
at every single build. Run 'scons configure=1' or delete sconf.cache
to force checks to be re-run.
Jelmer, I think this stuff is cached in the .sconf_cache directory but
the message is still displayed and it looks like it caches the compiled
test object file not the actual result of the test.
(This used to be commit 9d001dc083937bbf5642af90bc8a8b1a27825de0)
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.

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)
otherwise we get the wrong result when comparing upper
case chars with lower case chars
(This used to be commit f6ea6e9382f954be819ec82e28598cdf9cf88661)
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.
