(ITS#8193) error in ldap logs
by JB0035697＠techmahindra.com 09 Jul '15

09 Jul '15

Full_Name: Bourguignon J-L Version: 2.4.35 OS: Sun OS 5.10 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (195.89.32.88) Hi all, I've searched on the web for this kind of error but I've not find any relevant answer. Is someone can explain what does means this following error : slapd(58): setsockopt(SO_KEEPALIVE) failed errno=22 (Invalid argument) It seems that when it appears, the process is still running but slapd process doesn't answer to queries anymore. The only way to solve it, it's to restart the process. Thx in advance for help. Brgds, Jean-Luc.

I only meant to talk about where mdb.c explicitly picks errno codes, like it does with EIO/ENOSPC.

In particular, if the error code comes from an underlying system call and accurately describes that failure, we should pass it through. If the failure is LMDB-specific, and not related to any particular system call, then we should define an MDB_* code for it. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

(ITS#8192) liblmdb confuses Windows error code with errno values
by h.b.furuseth＠usit.uio.no 08 Jul '15

08 Jul '15

Full_Name: Hallvard B Furuseth Version: LMDB_0.9.15 OS: Windows 7 with cygwin URL: Submission from: (NULL) (81.191.45.5) Submitted by: hallvard mdb_env_write_meta() loops to retry_write if ErrCode() == EINTR. That's ERROR_TOO_MANY_OPEN_FILES = 4 on Windows. New in 0.9.15. == This one is older, in mdb_env_setup_locks(). Also wrong on Windows: rc = ErrCode(); if (rc && rc != EACCES && rc != EAGAIN) I don't know what that code is doing. I think that belongs under if ((rc = mdb_env_excl_lock(env, excl))) goto fail; where it would read as if (*excl <= 0 && (rc = ErrCode()) && rc != EACCES && rc != EAGAIN) ==D%D ENOENT confusion: mdb_env_read_header() can explicitly return ENOENT, but only as an internal code. So mdb_strerror() should drop ENOENT. We can rename/renumber it to avoid confusion: /* Internal result codes, not exposed outside liblmdb */ #define MDB_FILE_NEW (MDB_LAST_ERRCODE + 9) (above instead of MDB_NO_ROOT for easier cherry-picking.) OTOH lmdb.h lists "ENOENT - the directory specified by the path parameter doesn't exist." That's not related to the above. It should be "ENOENT (Unix) or ERROR_PATH_NOT_FOUND (Windows) - ..." Or maybe the doc for this code should say something more general, or simply be omitted. I found the Windows code by testing @ Windows. Reading Windows doc did not help. == Finally, I suggest we replace the explicit EIO/ENOSPC returns with either a new MDB code or #define MDB_EIO EIO on Unix and something else on Windows. (I think ENOSPC should be EIO too, there could be other reasons for a short write.) Then we can drop those from mdb_strerror() too.

(ITS#8191) mdb_txn_commit(empty txn) does not sync
by h.b.furuseth＠usit.uio.no 07 Jul '15

Full_Name: Hallvard B Furuseth Version: LMDB_0.9.15 OS: URL: Submission from: (NULL) (81.191.45.5) Submitted by: hallvard mdb_txn_commit(txn which made no changes) does not mdb_env_sync(), but lmdb.h says several times that Commit flushes buffers to disk. My feeling is that this is a quirk the user should not need to know about, and it's cleaner to sy r rather than to document it. OTOH I don't know if "fast commit of no-change txns" is a feature which someone expects to work, and if sync can be expensive even when there is no new data to flush. (I don't know what BDB does.)

(ITS#8190) LMDB cursor bug
by hyc＠openldap.org 07 Jul '15

07 Jul '15

Full_Name: Howard Chu Version: LMDB 0.9.15 OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (78.155.234.0) Submitted by: hyc In mdb_cursor_set(SET_RANGE) a call to mdb_cursor_sibling is used if the matching key wasn't found on the current page. If this call fails, the EOF flag should be set on the cursor but isn't. Subsequent attempts to call mdb_cursor_next() will read garbage data. A fix is coming shortly.

Re: (ITS#8185) Clarification/enhancement request: purging stale pwdFailureTime attributes

Ok -- I'm probably not understanding enough about your particular scenario to fully appreciate the concerns that you express. But I think there could be ways to address them in this enhancement -- for instance, by adding optional parameter(s) like ppolicy_purge_failures <nfailures> and/or ppolicy_purge_olderthan <timestamp>, which could then be configured to accommodate the scenario you describe. At this point, I'll think I'll leave it up to the OpenLDAP developers as to how they want to proceed on this, and/or to ask for more information. Thanks for the discussion Michael. Regards, -Kartik
