I had a couple of seg. faults when resync'ing my servers after upgrading to the upcoming 2.4.16 release. Looks as if a copy of the backend must be used when testing the filter in syncprov_matchops. See the gdb output at the end. Note, some function names are incorrect due to optimization. A fix is coming.
The fix makes no sense, or the problem has not yet been analyzed sufficiently. Nobody in that call chain should be zeroing out bd_info. And if someone *is*, then it will happen in *whatever* BackendDB structure is currently being used.
Explain the real cause of the problem, and why the fix is correct.
The problem is not zeroing of bd_info, it is that the entire op2.o_bd points to garbage, as the gdb output shows. I did forgot to print ss->s_op->o_bd though. op2 is a copy of *ss->s_op, but op2.o_bd and ss->s_op->o_bd differ. The content of *ss->s_op->o_bd looks reasonable.
The copying of *ss->s_op into op2 was introduced in rev 1.233 as a fix to ITS#5486. It doesn't say why this was the correct fix, but I assume it was done because something could modify *ss->s_op while the filter was being tested.
Yes of course, particularly op->o_callback.
Btw, the gdb output from ITS#5486 shows a db with similar garbage, so I suspect that these ITSes are related.
Assuming that something could mess with ss->s_op they might as well mess with ss->s_op->o_bd. The copying of the op->o_bd that takes place all around is a nightmare! I have no clue as to who modified *ss->s_op and/or *ss->s_op->o_bd, and I'm not very satisfied with the fact that something did. Finding out why this happened may be the correct fix.
Yes, that's my point.
Down the road we need to fix things so that all this copying is unnecessary; it just involves adding an op->o_bd_info field so that we no longer need to change anything in the op->o_bd itself.
YES! Would defining o_bd_info as o_bd->bd_info in the meantime ease the transition? That would allow us to fix the code that accesses bd_info step by step before actually making the real fix.
This would be a 2.5.x change; I'd rather not start this before we have a new 2.4 Stable release.
But in the meantime, we need to find out why an invalid op->o_bd is there. Most likely some lower function temporarily put a stack'd copy in there and didn't restore the original value before returning. And again, if that's the case, then it doesn't matter what value you set higher up, copy or not it will still point to garbage.
I'm more afraid we have a race condition here. I.e, thread A puts a pointer to a stack copy of the BackendDB into ss->s_op->o_bd. matchops in thread B copies this op into op2 before thread A restores the original o_bd. Leaving thread B with a pointer to junk in op2.o_bd.
Some more gdb output below, thread 2 looks suspicious here. Thread 1 was the failing one, its ss->s_op is the same as the op argument passed as argument in thread 2.
OK, that's the real problem. When a persistent search starts, it's recorded using the op of the active search (ss->s_op), while it's in refresh phase. When the refresh phase ends and it goes into persist, then the op is detached from the connection manager's control, and ss->s_op is replaced by a copy. But if writes occur while the refresh is still happening, they'll be referencing ss->s_op which is still the active refresh op.
The fix should be to use the current op's op->o_bd; each of the threads is executing in the same database so the current thread's o_bd should be functionally equivalent to the s_op's o_bd. There's no reason to make a new copy of the db.
