(LMDB) Correct use of mdb_env_sync
by Pierre Chapuis 16 Dec '15

16 Dec '15

I am having a hard time understanding how exactly mdb_env_sync should be used. Suppose I have an environment with MDB_NOSYNC and I do not use MDB_WRITEMAP. I still want to sync at some points, which is why mdb_env_sync exists. But I wonder: - How does it interact with transactions? Is it safe (or necessary) to call it outside of a transaction? During a read-only transaction? During a write transaction? - What about thread safety? Can it be called concurrently with writes? Can it be … [View More]

Hello guys! I tried to deploy openldap replica on Ubuntu 14.04. I copy database via slapcat(slapadd) and slapd.conf from another replica(Centos 6.7 with OpenLDAP: slapd 2.4.40).

ldapmodify failing with large attribute
by Geoff Swan 15 Dec '15

15 Dec '15

I have a problem appearing where a large (16.6MB approx) value is to be saved to an attribute (certificateRevocationList). Prior to the value being this large, ldapmodify had no problems updating it. However it appears to have crossed some magic threshold where it will no longer be accepted, and aborts with: ldap_modify: Can't contact LDAP server (-1) The ldapmodify operation is being performed on the ldap host machine using the ldap root user with simple password authentication.

by Angel L. Mateo 14 Dec '15

14 Dec '15

Hello, I have a few ubuntu 14.04 servers running slapd 2.4.31 installed from ubuntu packages. Now I want to upgrade these servers to last openldap version, so I I have downloaded 2.4.43 and compiled from myself. Since then, whenever I tri to make a change in the config, slapd crashes with: Dec 11 08:34:56 canis30 slapd[9640]: conn=1000 op=0 RESULT tag=97 err=0 text= Dec 11 08:34:56 canis30 slapd[9640]: conn=1000 op=1 MOD dn="olcDatabase={3}hdb,cn=config" Dec 11 08:34:56 canis30 slapd[… [View More]

(LMDB) read-only transactions and DBI handles
by Viacheslav Usov 11 Dec '15

11 Dec '15

I have a question about mdb_dbi_open and the handles it returns. The official documentation suggests to me that mdb_dbi_open is supposed to be called early on and then the obtained handle should just be reused by other transactions without any further calls to mdb_dbi_open and mdb_dbi_close. The code in sample-mdb.txt does that (ignoring the final close-all sequence). The sample also uses mdb_txn_abort to end a read-only transaction, which I take as the recommended way to end read-only … [View More]

LMDB transcations - how
by Christian Sell 11 Dec '15

11 Dec '15

Hello, I am looking for advice about how to best handle LMDB transactions and to avoid pitfalls. Our application is multi-threaded, with several threads accessing persistent data in a streaming fashion (reading lots of data sequentially). I am also not sure that it will be practical to stick with one transaction per thread, so MDB_NOTLS may be needed. In this scenario, there are few "natural" transaction boundaries, which is why I am asking when or how often a commit/abort (or reset/renew) … [View More]
