If the call fails because O_DIRECT, in a "tmpfs" in my Fedora 19 '/tmp', the file is left created anyway! so the retry fails because O_EXCL|O_CREAT. I consider this undocumented behavior for "open", buggy or at least ugly. (A simple test program in ftp://ftp.msg.com.mx/pub/varios/o_direct.c) I propose the following: ======== --- a/liblmdb/mdb.c 2013-09-05 17:31:01.498090281 -0500 +++ b/liblmdb/mdb.c 2013-09-13 14:45:00.918717292 -0500 @@ -4250,9 +4250,16 @@ /* The OS supports O_DIRECT, try with it */ newfd = open(lpath, O_WRONLY|O_CREAT|O_EXCL|O_DIRECT, 0666); /* But open can fail if O_DIRECT isn't supported by the file system - * so retry without the flag + * so retry without the flag. + * + * Sept 13 2013. + * On a tmpfs, at least, an open with O_DIRECT fails, + * BUT the file is created anyway!! + * Fortunately seems that other errors are reported before EINVAL + * So, we need to remove it before retry open. */ if (newfd == INVALID_HANDLE_VALUE && ErrCode() == EINVAL) + (void)unlink(lpath) , #endif newfd = open(lpath, O_WRONLY|O_CREAT|O_EXCL, 0666); #endif ========= What do you think?

This is why, again, you could use the LTB packages I pointed you at. They don't replace the existing ldap libraries, etc, on the server. They install into their own location (/usr/local I believe). Then you don't have to build it yourself, and you can actually be on something current. --Quanah -- Quanah Gibson-Mount Lead Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration

That's not so easy how you think because this is a running producive Server and i don't have the time to build OpenLDAP 2.4 for CentOS 5.9, thats why i try to use an ProxyCache.

Just use one of the freely available source rpm and build from that.

And my Destination LDAP where the ProxyCache works in on LDAP 2.4.23.

Hi Stef, Thanks! In the future then, if it is an issue with the current 2.4 release series still, you can just put RE24 as the version. ;) Then I won't spend time trying to see if it's a known issue already fixed via the changes log. --Quanah -- Quanah Gibson-Mount Lead Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration

This patch is against master. However master cldap support is broken in additional ways, and I'll be filing further bugs/patches. Cheers, Stef
