Maybe there should be an mdb_txn_info() function instead: typedef struct MDB_txninfo { int mt_lib_version; /* library version, set by liblmdb */ MDB_env *mt_env; } MDB_txninfo; #define mdb_txn_info(txn, ti) mdb_txn_xinfo(txn, ti, MDB_VERSION_FULL) int mdb_txn_xinfo(MDB_txn *txn, MDB_txninfo *ti, int api_version); The version parameter is so we can extend MDB_txninfo later, and liblmdb will know how much of MDB_txninfo it can fill in. The caller can zero out the txninfo before the call, so he'll be prepared if an older liblmdb does not support and set all fields. -- Hallvard

Re: (ITS#7660) LMDB: Proposing a small addition to the API: mdb_txn_env

by sog＠msg.com.mx

Sure! In fact I want the module to become the "oficial" Perl's LMDB module. Right now I'm writing an extensive test battery that is uncovering some bad assumptions, undocumented features, and/or bugs in the library. Please expect the announce of an alpha release early in the next week in openldap-devel. I'm Just waiting for a version of LMDB in git with the issues solved. Salvador.

(ITS#7660) LMDB: Proposing a small addition to the API: mdb_txn_env

by sog＠msg.com.mx

Full_Name: Salvador Ortiz Version: 24 OS: Linux URL: ftp://ftp.msg.com.mx/pub/varios/Add-mdb_txn_env-to-API.patch Submission from: (NULL) (187.162.45.111) I'm writing from scratch a wrapper of LMDB for the Perl language, the project is progressing fast and looks very promising. Thank you for a wonderful library! I want to avoid as much as possible the need to duplicate LMDB's state in perl, in particular dbi's flags, so I need a method to obtain the MDB_env from a MDB_txn, but the required API is missing. In the same spirit of mdb_cursor_txn or mdb_cursor_dbi I propose adding mdb_txn_env. Provided a patch against gitorious mdb.master. Any comments or questions more than welcome. Regards. Salvador

(ITS#7659) slapd refuses caseIgnoreMatch for Country String

by cyrille.maucci＠hp.com

Full_Name: Cyrille MAUCCI Version: 2.4.32 OS: RHEL5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (15.203.169.125) Hello openldap'ers, as a follow-up of our discussion on http://www.openldap.org/lists/openldap-technical/201307/msg00042.html, I'm creating an ITS to track the fact that slapd seems to refuse caseIgnoreMatch matching rule for Country String. Initial description of the bug can be found hereafter, to which Howard are ack'ed "Looks like a bug, schema_init.c doesn't list Country String as a compatible syntax here. You should submit an ITS for this." Many thanks in advance ++Cyrille BUG DESCRIPTION: When I have this piece of schema included in my slapd.conf file… attributetype ( 1.3.6.1.4.1.11.11.1.1.1.1.402 NAME ( 'TestCountryString' 'TestCountryStringSyn' ) DESC 'Test Country String' EQUALITY caseIgnoreMatch ORDERING caseIgnoreOrderingMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.11 SINGLE-VALUE ) … my 2.4.32 slapd –Tt complains with this error: line 8 attributetype: AttributeType inappropriate matching rule: "caseIgnoreMatch". My understanding of http://tools.ietf.org/html/rfc4517 is that caseIgnoreMatch is valid for country string: "The caseIgnoreMatch rule compares an assertion value of the Directory String syntax to an attribute value of a syntax (e.g., the Directory String, Printable String, Country String, or Telephone Number syntax) whose corresponding ASN.1 type is DirectoryString or one of its alternative string types. " Could you confirm whether this is a bug in openldap or simply a misunderstanding from me ?
