2010-04-11subunit: Support formatting compatible with upstream subunit, for consistency.Jelmer Vernooij1-1/+1
Upstream subunit makes a ":" after commands optional, so I've fixed any places where we might trigger commands accidently. I've filed a bug about this in subunit.
2010-04-06s4-waf: fixed waf distcheck for our standalone libs and s4Andrew Tridgell1-0/+4
2010-04-06s4-waf: added simple 'waf test' support for tdb, talloc and ldbAndrew Tridgell1-0/+6

2010-04-06s4-waf: move to a universal method of recursing into subdirsAndrew Tridgell1-3/+3
This works with both standalone lib builds and bundled builds

2010-04-06s4-waf: avoid having to run waf configure before waf distAndrew Tridgell1-2/+3
This should be useful for building tarballs from a clean checkout
2010-04-06s4-waf: allow standalone tarball build of librariesAndrew Tridgell1-2/+9
2010-04-06s4-waf: added 'waf dist' to our standalone libs as wellAndrew Tridgell1-1/+3
2010-04-06s4-waf: added implied_deps for system librariesAndrew Tridgell1-1/+2
when we use a system version of a library such as talloc, then we no longer get the automtica dependency propogation of talloc implying libreplace. That means we don't get the includes for libreplace, which means things can fail to build. To fix this this change adds an implied_deps option to CHECK_BUNDLED_SYSTEM(), which tells the samba_deps module to add an implied dependency on the listed targets if the system library is chosen.
2010-04-06s4-waf: support the use of system librariesAndrew Tridgell1-5/+10
distros can set --bundled-libraries=NONE to force use of all system libraries. If the right version isn't found then configure will fail. Users may choose which libraries to use from the system, and which to use bundled libs. The default is to try system libs, and use them if their version matches the one in the source tree.

2010-02-24tdb: handle processes dying during transaction commit.Rusty Russell3-0/+86
tdb transactions were designed to be robust against the machine powering off, but interestingly were never designed to handle the case where an administrator kill -9's a process during commit. Because recovery is only done on tdb_open, processes with the tdb already mapped will simply use it despite it being corrupt and needing recovery. The solution to this is to check for recovery every time we grab a data lock: we could have gained the lock because a process just died. This has no measurable cost: here is the time for tdbtorture -s 0 -n 1 -l 10000: Before: 2.75 2.50 2.81 3.19 2.91 2.53 2.72 2.50 2.78 2.77 = Avg 2.75 After: 2.81 2.57 3.42 2.49 3.02 2.49 2.84 2.48 2.80 2.43 = Avg 2.74 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-02-24tdb: add -k option to tdbtortureRusty Russell1-57/+142
To test the case of death of a process during transaction commit, add a -k (kill random) option to tdbtorture. The easiest way to do this is to make every worker a child (unless there's only one child), which is why this patch is bigger than you might expect. Using -k without -t (always transactions) you expect corruption, though it doesn't happen every time. With -t, we currently get corruption but the next patch fixes that. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: don't truncate tdb on recoveryRusty Russell1-10/+0
The current recovery code truncates the tdb file on recovery. This is fine if recovery is only done on first open, but is a really bad idea as we move to allowing recovery on "live" databases. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: remove lock opsRusty Russell4-40/+22
Now the transaction code uses the standard allrecord lock, that stops us from trying to grab any per-record locks anyway. We don't need to have special noop lock ops for transactions. This is a nice simplification: if you see brlock, you know it's really going to grab a lock. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: rename tdb_release_extra_locks() to tdb_release_transaction_locks()Rusty Russell3-13/+9
tdb_release_extra_locks() is too general: it carefully skips over the transaction lock, even though the only caller then drops it. Change this, and rename it to show it's clearly transaction-specific. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: cleanup: remove ltype argument from _tdb_transaction_cancel.Rusty Russell1-17/+13
Now the transaction allrecord lock is the standard one, and thus is cleaned in tdb_release_extra_locks(), _tdb_transaction_cancel() doesn't need to know what type it is. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: tdb_allrecord_lock/tdb_allrecord_unlock/tdb_allrecord_upgradeRusty Russell3-29/+62
Centralize locking of all chains of the tdb; rename _tdb_lockall to tdb_allrecord_lock and _tdb_unlockall to tdb_allrecord_unlock, and tdb_brlock_upgrade to tdb_allrecord_upgrade. Then we use this in the transaction code. Unfortunately, if the transaction code records that it has grabbed the allrecord lock read-only, write locks will fail, so we treat this upgradable lock as a write lock, and mark it as upgradable using the otherwise-unused offset field. One subtlety: now the transaction code is using the allrecord_lock, the tdb_release_extra_locks() function drops it for us, so we no longer need to do it manually in _tdb_transaction_cancel. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: suppress record write locks when allrecord lock is taken.Rusty Russell1-0/+9
Records themselves get (read) locked by the traversal code against delete. Interestingly, this locking isn't done when the allrecord lock has been taken, though the allrecord lock until recently didn't cover the actual records (it now goes to end of file). The write record lock, grabbed by the delete code, is not suppressed by the allrecord lock. This is now bad: it causes us to punch a hole in the allrecord lock when we release the write record lock. Make this consistent: *no* record locks of any kind when the allrecord lock is taken. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: cleanup: always grab allrecord lock to infinity.Rusty Russell1-7/+3
We were previously inconsistent with our "global" lock: the transaction code grabbed it from FREELIST_TOP to end of file, and the rest of the code grabbed it from FREELIST_TOP to end of the hash chains. Change it to always grab to end of file for simplicity and so we can merge the two. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: remove num_locksRusty Russell2-11/+2
This was redundant before this patch series: it mirrored num_lockrecs exactly. It still does. Also, skip useless branch when locks == 1: unconditional assignment is cheaper anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: use tdb_nest_lock() for seqnum lock.Rusty Russell1-3/+3
This is pure overhead, but it centralizes the locking. Realloc (esp. as most implementations are lazy) is fast compared to the fnctl anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: use tdb_nest_lock() for active lock.Rusty Russell2-5/+18
Use our newly-generic nested lock tracking for the active lock. Note that the tdb_have_extra_locks() and tdb_release_extra_locks() functions have to skip over this lock now it is tracked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-22tdb: use tdb_nest_lock() for open lock.Rusty Russell3-15/+10
This never nests, so it's overkill, but it centralizes the locking into lock.c and removes the ugly flag in the transaction code to track whether we have the lock or not. Note that we have a temporary hack so this places a real lock, despite the fact that we are in a transaction. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: use tdb_nest_lock() for transaction lock.Rusty Russell2-32/+23
Rather than a boutique lock and a separate nest count, use our newly-generic nested lock tracking for the transaction lock. Note that the tdb_have_extra_locks() and tdb_release_extra_locks() functions have to skip over this lock now it is tracked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: find_nestlock() helper.Rusty Russell1-28/+23
Factor out two loops which find locks; we are going to introduce a couple more so a helper makes sense. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
