That makes it easier when you have to modify the script along with the code in the source three: old branches continue to use the old version of the script with the old source version, new branches can use the new script with the new source changes. (But it's up to you what works best in this particular case). > + "nextBuild": myNextBuild, The myNextBuild() function selects among mariadb branches, that's probably not very useful for a jdbc builder? > see. Maybe you can have a quick look, if you got time? Would be a great > help. Ok, I will go through it all and try to get everything working. It's probably better to add a separate configuration (branch map, schedulers, builders) for the jdbc driver to not get it mixed up with the mariadb source builds. - Kristian.

[Maria-developers] API Documentaion for Replication Features
by Gordan Bobic 03 Dec '12

03 Dec '12

Hi, I have a need for replicating data from multiple masters (independent data going to different tables). I have looked into the following with no success: Tungsten: Slow, CPU hungry, outrageously bloated, and unacceptably unreliable (replication will stall silently at times, and the only way to resume it is to offline and online the replication service). mysql-replication-listener: Just about got it to work with local binlogs, but haven't managed to get it to connect via TCP to a MySQL server. So what I was hoping to do is write something based on the existing MySQL code since at least that should "just work". The problem is - I am completely unfamiliar with MySQL internals, and I haven't found any function level API documentation. So, would anyone here be kind enough to point me at the specific bits of code in MySQL that handle: 1) Slave TCP connections to the master and binlog fetching 2) Binlog parsing 3) Config file parsing In the longer term I'd like to write a patch that adds multiple-master functionality into MySQL itself. For configuring it, I was thinking about the following WRT configuration in my.cnf with multiple section instances, e.g.: [replicator] server-id=12345 master-host=server1 master-port=3306 master-user=user1 master-password=password1 replicate-do-table=db1.table1 [replicator] server-id=12345 master-host=server2 master-port=3306 master-user=user2 master-password=password2 replicate-do-table=db2.table2 etc. Any pointers would be greatly appreciated. If somebody here is already undertaking a similar effort, I would rather like to lend a hand. TIA. Gordan
