They use talloc_tos() internally: hoist that up to the callers, some
of whom don't want to us talloc_tos().
A simple patch, but hits a lot of files.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
talloc_stackframe() stacks, so if you forget to free one, the outer
one will free it. However, it's not a good idea to rely too heavily
on this behaviour: it can lead to delays in the release of memory or
destructors.
I had an elaborate hack to make sure every talloc_stackframe() was
freed in the exact same function it was allocated, however all bugs it
caught were simply lazy freeing, so this patch just checks for that.
This doesn't check for stackframes we don't free up on exit: that would
be nice, but uncovers some uncomfortable (but probably harmless) cases.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
The only reason we make one stackframe parent of the next is so we use
our parent's pool. That doesn't make sense if we're a new pool, and
wouldn't work anyway.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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>
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%.

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.

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.

(As suggested by Stefan Metzmacher, based on the change to ntdb.)
Since commit ec96ea690e, 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).

The first function is ntdb_new: this is preferred over ntdb_open, as
it makes the ntdb_context returned (and all NTDB_DATA returned from
ntdb_fetch) valid talloc pointers.
The API is very similar to tdb_wrap_open().

hack (and it's great for speeding up testing!).

In particular, this tests that we can store enough records to make the
database expand while we map the given record. We use a global lock for
this, but it could happen in theory with another process.
It also tests the that we can recurse inside ntdb_parse_record().
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Since we have a readlock, any write will grab a write lock: if it happens
to be on the same bucket, we'll fail.
For that reason, enforce read-only so every write operation fails
(even for NTDB_NOLOCK or NTDB_INTERNAL dbs), and document it!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
NTDB_INTERNAL databases need to malloc and copy to keep old versions
around if we expand, in a similar way to the manner in which keep old
mmaps around.
Of course, it only works for read-only accesses, since the two copies
are not synced.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This means keeping the old mmap around when we expand the database.
We could revert to read/write, except for platforms with incoherent
mmap (ie. OpenBSD), where we need to use mmap for all accesses.
Thus we keep a linked list of old maps, and unmap them when the last access
finally goes away.
This is required if we want ntdb_parse_record() callbacks to be able
to expand the database.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Since we can have multiple openers, we should leave the mmap in place
for the other openers to use. Enhance the test to check the bug (it
still works, because without mmap we fall back to read/write, but
performance would be terrible!).

Since we've given up on expansion, let them frob the hashsize again.
We have attributes, so we should use them for optional stuff like
this.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
TDB2 started with a top-level hash of 1024 entries, divided into 128
groups of 8 buckets. When a bucket filled, the 8 bucket group
expanded into pointers into 8 new 64-entry hash tables. When these
filled, they expanded in turn, etc.
It's a nice idea to automatically expand the hash tables, but it
doesn't pay off. Remove it for NTDB.
1) It only beats TDB performance when the database is huge and the
TDB hashsize is small. We are about 20% slower on medium-size
databases (1000 to 10000 records), worse on really small ones.
2) Since we're 64 bits, our hash tables are already twice as expensive
as TDB.
3) Since our hash function is good, it means that all groups tend to
fill at the same time, meaning the hash enlarges by a factor of 128
all at once, leading to a very large database at that point.
4) Our efficiency would improve if we enlarged the top level, but
that makes our minimum db size even worse: it's already over 8k,
and jumps to 1M after about 1000 entries!
5) Making the sub group size larger gives a shallower tree, which
performs better, but makes the "hash explosion" problem worse.
6) The code is complicated, having to handle delete and reshuffling
groups of hash buckets, and expansion of buckets.
7) We have to handle the case where all the records somehow end up with
the same hash value, which requires special code to chain records for
that case.
On the other hand, it would be nice if we didn't degrade as badly as
TDB does when the hash chains get long.
This patch removes the hash-growing code, but instead of chaining like
TDB does when a bucket fills, we point the bucket to an array of
record pointers. Since each on-disk NTDB pointer contains some hash
bits from the record (we steal the upper 8 bits of the offset), 99.5%
of the time we don't need to load the record to determine if it
matches. This makes an array of offsets much more cache-friendly than
a linked list.
Here are the times (in ns) for tdb_store of N records, tdb_store of N
records the second time, and a fetch of all N records. I've also
included the final database size and the smbtorture local.[n]tdb_speed
results.
Benchmark details:
1) Compiled with -O2.
2) assert() was disabled in TDB2 and NTDB.
3) The "optimize fetch" patch was applied to NTDB.

Analysis:
1) TDB wins on small databases, beating TDB2 by ~15%, NTDB by ~10%.
2) TDB starts to lose when hash chains get 10 long (fetch 10% slower
than TDB2/NTDB).
3) TDB does horribly when hash chains get 100 long (fetch 4x slower
than NTDB, 5x slower than TDB2, insert about 2-3x slower).
4) TDB2 databases are 40% larger than TDB1. NTDB is about 15% larger
than TDB1
This is designed to allow us to make ntdb_context (and NTDB_DATA returned
from ntdb_fetch) a talloc pointer. But it can also be used for any other
alternate allocator.

The performance numbers for transaction pagesize are indeterminate:
larger pagesizes means a smaller transaction array, and a better
chance of having a contiguous record (more efficient for
ntdb_parse_record and some internal operations inside a transaction).
On the other hand, large pagesize means more I/O even if we change a
few bytes.
But it also controls the multiple by which we will enlarge the file,
and hence the minimum db size. It's 4k for tdb1, but 16k seems
reasonable in these modern times.

If we create the database with a free record which pads it out to
NTDB_PGSIZE, we can remove this last-page-is-different logic.
Of course, the fake ntdbs we create in our tests now also need to be
multiples of NTDB_PGSIZE, so we change some numbers there too.

ntdb uses tdb's transaction code, and it has an undocumented but implicit
assumption: that the transaction recovery area is always aligned to the
transaction pagesize. This means that no block will overlap the recovery
area.
This is maintained by rounding the size of the database up, so do the same
for ntdb.

We were missing the last few bytes. Found by 100 runs of ntdbtorture
-t -k.
The transaction test code didn't catch this, because usually those
last few bytes are irrelevant to the actual contents of the database.
We fix the test.

Our external test helper is a bit primitive when it comes to doing STORE or
FETCH commands: let us specify the data we expect, instead of assuming it's
the same as the key.

This is a fairly common pattern in Samba, and if we log an error on
every open it spams the logs. On the other hand, other errors are
potentially more serious, so we still use NTDB_LOG_ERROR on them.

We document that the child of a fork() can do a brunlock() if the parent
does a brlock: we should not log an error when they do this.
Also, test the case where we fork() and return inside a parse function
(which is allowed).

In tdb, we grab the open lock immediately after we open the file. In
ntdb, we usually did some work first. tdbtorture managed to get in
before the creator grabbed the lock:
testing with 3 processes, 5000 loops, seed=1338246020
ntdb:torture.ntdb:IO Error:ntdb_open: torture.ntdb is not a ntdb file
29023:torture.ntdb:db open failed
At cost of a little duplicated code, we can reduce the race.

It was a hack to make compatibility easier. Since we're not doing that,
it can go away: all callers must use the return value now.

This renames everything from tdb2 to ntdb: importantly, we no longer
use the tdb_ namespace, so you can link against both ntdb and tdb if
you want to.
This also enables building of standalone ntdb by the autobuild script.

Judging by code it's tdb1, where you needed to free old key's dptr
manually.

This commit changes the default file server to be s3fs. Existing
installs wishing to keep the ntvfs file server need to set this in
their smb.conf:
server services = +smb -s3fs
dcerpc endpoint services = +winreg +srvsvc
