[Issue 9735] New: [PATCH] try hard to find free space if database cannot grow

https://bugs.openldap.org/show_bug.cgi?id=9735 Issue ID: 9735 Summary: [PATCH] try hard to find free space if database cannot grow Product: LMDB Version: 0.9.24 Hardware: All OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: libor.peltan(a)nic.cz Target Milestone: --- Created attachment 851 --> https://bugs.openldap.org/attachment.cgi?id=851&action=edit Patch fixing the issue "try hard to find free space if database cannot grow" Note: - the issue is the same in version 0.9.70 (git) Situation: - the database had already grown to its limit (mapsize) in the past - overflow pages are used heavily as stored values are usually several pages long - free space got fragmented Problem: - attempt to insert new value results in MDB_MAP_FULL despite there is free space available Cause: there is a heursitic in mdb_page_alloc() that gives up searching for free space chunk if this would take too much time. This is useful when the database can still grow, as it balances performance with space usage. However, if the database can no longer grow, it prevents inserting new values. Solution: detect early on in mdb_page_alloc() if the database can grow, and if not, let it try hard to search for free space.

[Issue 9953] New: Push replication issue for the pwdHistory attribute
by openldap-its＠openldap.org 10 Jul '23

https://bugs.openldap.org/show_bug.cgi?id=9953 Issue ID: 9953 Summary: Push replication issue for the pwdHistory attribute Product: OpenLDAP Version: 2.4.57 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: overlays Assignee: bugs(a)openldap.org Reporter: dh(a)dotlan.net Target Milestone: --- Hello, I'm using a master ldap instance with a push replication instance to external slaves using the ldap backend on Debian 11 (2.4.57) and I came across some replication issues that forces me to drop the slave dbs and do a manually fullsync everything this error occurs. The problem =========== I know that replication and maintaining a password policy is a complicated task, especially since the ppolicy overlay must be loaded and active in every instance (master, push instance, slave). This problem leads to interesting challanges. First, I encountered a problem where pwdChangedTime would be duplicate because the ppolicy overlay of the push instance and the back_ldap/slave instance would like to set it (which leads to a duplicate attribute error). To fix problem I backported the patch [1] to my local version of the slapd packages. After this problem was fixed, I've encountered the next problematic attribute: "pwdHistory". I've play around with some syncrepl settings, but in the end, it seems to be a similar issue. It looks likes the pwdHistory attribute is not yet present on the slave and both instances (push and slave) try to add the pwdHistory Attributes which leads to a problem where both entries collied (pwdHistory: value #0 already exists). For whatever reason pwdHistory doesn't show up as modified field on the slave in the MOD request. But anyways. Something seems to be wrong, and it could a similar replication issue compared with pwdChangedTime I've lookup into the change history of the ppolicy.c file in the 2.5 and 2.6 branch but couldn't find a newer commit that would address this issue. Does anyone has encountered a similar issue? I've not played around with the 2.5 or 2.6 version, but looking at the code, I've either not seen a fix or the problem might still exist, hopefully I am wrong. Any suggestions? -- best regards Daniel Hoffend [1] https://github.com/openldap/openldap/commit/7a34f46d1cabe8e80937d5167b62152… Setup ===== Host Master - Debian 11 slapd 2.4.57+dfsg-3 - slapd master instance with cn=config - push replikation instance with simple config (syncrepl from localhost, write to backend ldap) Host Slave - Debian 11 slapd 2.4.57+dfsg-3 - Readonly slave On all 3 instances ppolicy is enabled otherwise the operational attributes would be not known/available and sync of locked accounts or per account selected password policy assignment wouldn't work.

[Issue 9736] New: pwrite bug in OSX breaking LMDB promise about the maximum value size
by openldap-its＠openldap.org 22 May '23

22 May '23

https://bugs.openldap.org/show_bug.cgi?id=9736 Issue ID: 9736 Summary: pwrite bug in OSX breaking LMDB promise about the maximum value size Product: LMDB Version: unspecified Hardware: All OS: Mac OS Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: renault.cle(a)gmail.com Target Milestone: --- Hi, I was working with LMDB and found an issue when trying to write a value of approximately 3.3GiB in the database, I dive into the LMDB source code of the mdb_put method using the lldb debugger and found out that it was not related to an issue in LMDB itself but rather a bug in the pwrite function of the Mac OS libc implementation. The pwrite function is given four parameters, the file descriptor, the buffer, the count of bytes to write from the buffer and, the offset of where to write it in the file. On Mac OS the count of bytes is a size_t that must be a 64bits unsigned integer but when you call pwrite with a number bigger or equal to 2^31 it returns an error 22 (invalid argument). LMDB was returning a 22 error from the mdb_put call and not an EINVAL because the error was cause by an internal issue and not something catchable by LMDB. I am not sure about what we can do, can we implement this single pwrite [1] as multiple pwrite with counts smaller than 2^31 in a loop, just for Mac OS? Like for Windows where we do specific things for this operating system too? I also found this issue on the RocksDB repository [2] about a similar problem they have with pwrite and write on Mac OS it seems. I understand that this is not a real promise that LMDB is specifying but rather an "in theory" rule [3]. Thank you for your time, kero [1]: https://github.com/LMDB/lmdb/blob/01b1b7dc204abdf3849536979205dc9e3a0e3ece/… [2]: https://github.com/facebook/rocksdb/issues/5169 [3]: http://www.lmdb.tech/doc/group__mdb.html#structMDB__val -- You are receiving this mail because: You are on the CC list for the issue.
