For fixing the observed problem: Improving the indexer sounds great in any case, go ahead:-) No idea how much work it is. tpool.c was code I knew how to change, so I did. Will it then be as reactive as ordinary tasks, also for large databases? Merely "much faster than now" might be very different from "fast enough to not be a problem". In general: I do think slapd should recognize that some tasks can be notably slower that others. Latency is in part a scheduling issue, and it can hit particularly hard at pauses. Currently tpool does not help with that. Setspeed can help. Except if a run-time config change removes the database/overlay, I'm not up to date about whether that can happen. But that's so for rescheduling the indexer as well. back-sock/back-shell can also be slow, so I expect they have the same issue. If they "fix" that with pool_idle() before reading results, I expect config changes could hose the operation badly. Same with setspeed() in the backend, it'd be too late. Maybe if the database declared itself "slow", then slapd could setspeed() before dispatching the operation to the database.

So there's nothing safe about letting the > fast task progress while the slow task is still running Fast tasks still wait for *running* slow tasks. And when there is no pause involved, slow tasks get scheduled normally. This is only about scheduling when something wants a pause. setspeed() does CHECK_PAUSE, standing aside for faster tasks. Then, a fast task which wants a pause (cn=config change #2) won't block other fast tasks while a slower task (indexer) is running. So normal tasks will keep getting scheduled, instead of slapd locking up for them. This all depends on there being only a few config changes/slow tasks at any time, since they do occupy a thread. -- You are receiving this mail because: You are on the CC list for the issue.

I'll put a suggestion here that we discussed previously: to support this checkpointing for pauses/shutdowns, the indexer could be writing to a "scratch" database (whatever that means for each backend) along with resume data and move them into place when finished. You mentioned that for liblmdb, this would need support for a database to be renamed. -- You are receiving this mail because: You are on the CC list for the issue.

We should just be fixing this specific case of the indexer being a slow task, by implementing checkpointing into the indexer.

https://bugs.openldap.org/show_bug.cgi?id=9618 Issue ID: 9618 Summary: Sync'ing is not happening in MDB_WRITEMAP mode on Windows with mdb.master3 Product: LMDB Version: 0.9.29 Hardware: All OS: Windows Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: kriszyp(a)gmail.com Target Milestone: --- Created attachment 831 --> https://bugs.openldap.org/attachment.cgi?id=831&action=edit Revert back to using standard FlushViewOfFile/FlushFileBuffers to sync data with WRITEMAP mode on Windows With ITS#9017, Windows sync'ing is performed by using the write-through (and overlapped) writes, as it performs much better than FlushViewOfFile/FlushFileBuffers. However, this functionality has regressed on mdb.master3 because performing the writes is dependent on tracking and writing the list of dirty pages, which is not tracked in WRITEMAP mode. This means that on mdb.master3, with MDB_WRITEMAP, sync'ing is not really happening on Windows. I think it is probably preferable to not try to maintain an exception for dirty page tracking in WRITEMAP mode just for Windows. The attached patch reverts back to using the standard map/file sync procedure (FlushViewOfFile/FlushFileBuffers) to sync data when in WRITEMAP on Windows. This still maintains the (better performing) write-through based sync technique for standard, non-WRITEMAP mode on Windows. -- You are receiving this mail because: You are on the CC list for the issue.

Steps to Reproduce: connect to 2.5.5 slapd over IPv6 with tcp-wrappers enabled. Actual Results: access is always denied Expected Results: access permitted for IP addresses in /etc/hosts.allow Additional information: The problem seems to be that an IPv6 address is passed to hosts_ctl (~line 2324 in servers/slapd/daemon.c) as "[ipv6-address]" (with enclosing '[' and ']') - rather than "ipv6-address", e.g. the logged output is: warning: can't resolve hostname ([2001:630:3c1:212:a2d3:c1ff:fe25:eec3]): Name or service not known fd=19 DENIED from unknown ([2001:630:3c1:212:a2d3:c1ff:fe25:eec3] ... when compared to a 2.4.59 slapd: fd=19 DENIED from unknown (2001:630:3c1:212:a2d3:c1ff:fe25:eec3) IPv4 connections work OK.
