[Maria-discuss] Can not build MariaDB 10.0.30 and 10.1.22 with Visual Studio 2013
by Ayano Kosaka 22 Mar '17

22 Mar '17

Hi, I can not build MariaDB 10.0.30 and 10.1.22 with Visual Studio 2013 on Windows 7 Pro 64 bit. `identifier "int64_t" is undefined` occurs at `storage/xtradb/btr/btr0cur.cc`. It is probably caused by the following merge commit: [Merge branch 'merge-xtradb-5.6' into 10.0] https://github.com/MariaDB/server/commit/83da1a1e572d67588b66724b34fdb7f079… Before this commit, `ib_int64_t` (the typedef, which wraps compiler differences, in `../include/univ.i`) is used instead of `int64_t`. This error does not occur on VS2015, because it has `int64_t`. But VS2013 does not have `int64_t`. Were the supported compilers changed? Or, a bug or my environmental problem? Regards, Ayano Kosaka

Thanks for your answer, I understand perfectly, but this is an old system, I understand the procedure of the update, but I thought there was some old_mode configuration only to run that database with the options of mariadb 5.5.52 in mariadb 10.1.22.

[Maria-discuss] Missing MariaDB Seal logos?
by Colin Charles 20 Mar '17

20 Mar '17

Hi! Visiting: https://mariadb.com/kb/en/mariadb/branding-guidelines/ You’ll note that the Powered by MariaDB badges still exist (https://mariadb.org/about/logos/) — they should really say Powered by MariaDB Server But what is missing are all the seal logos? Currently beyond the archives at Wikimedia Commons (https://commons.wikimedia.org/wiki/File:Mariadb-seal-browntext.svg) they seem to have disappeared Is this just an oversight and something that needs fixing? Thanks -- Colin Charles, http://bytebot.net/blog/ twitter: @bytebot | skype: colincharles "First they ignore you, then they laugh at you, then they fight you, then you win." -- Mohandas Gandhi

[Maria-discuss] Questions to temporary myisam table files
by Hempel, Sebastian 20 Mar '17

20 Mar '17

Hallo, there is a known issue with the repair table function (MDEV-5871, MDEV-8475), which was fixed in MariaDB 10. Which is fine, but we have still MariaDB 5.5 server running. So we created our own repairtable function to work around this problem. For that function I like to know all possible file extensions for temporary myisam table files. For me temporary myisam table files are these files which are generated when calling "check table", "repair table" or other database functions. Thanks Sebastian

[Maria-discuss] Exclusive lock not working
by Jesse Schalken 20 Mar '17

20 Mar '17

I have a transaction that checks if a row exists with a particular value and if not, generates the data for that row and inserts it: -- schema CREATE TABLE test ( col INT, data TEXT, KEY (col) ); -- transaction START TRANSACTION; SELECT * FROM test WHERE col = 4 FOR UPDATE; -- If no results, generate data and insert INSERT INTO test SET col = 4, data = 'generated data goes here'; COMMIT; The problem I have is that if two copies of this transaction run concurrently (with the queries interleaved), they both pass the SELECT and deadlock on the INSERT. I would expect that the SELECT would acquire an exclusive lock on "col = 4" so only one transaction will proceed to insert, but the "FOR UPDATE" seems to behave as a shared lock instead. What is the correct way to write this transaction so only one copy proceeds to generate the "data" string and insert the row? (I originally posted this on Stack Overflow here <https://stackoverflow.com/questions/42547629/insert-row-if-not-exists-witho…> .) Thanks

[Maria-discuss] Fix different gtid-positions on domain 0 in multi-master
by Reinder Cuperus 17 Mar '17

17 Mar '17

Hello, After moving half of the databases on our primary master-master-cluster to a different cluster, we have a problem on our backup-server which is now a slave of both servers. Topology before: master1 <-> master2 -> backup-slave Topology during migrations: master1 <-> master2 -> backup-slave <-> master3 <-> master4 Final topology: master1 <-> master2 -> backup-slave <- master3 <-> master master4 The gtid_domain_ids before/during the migration were: master1/master2 : 0 master3/master4 : 20 Replication-settings: master2 -> backup: Replicate_Do_Domain_Ids: 0 master3 -> backup: Replicate_Do_Domain_Ids: 20 backup->master3: Replicate_Do_DB: DbToMigrate1,DbToMigrate2,etc Server version: 10.1.9 So after the migration, a typical gtid_position would be on: master1/2: 0-1-12345 master3/4: 0-1-12345,20-21-5678 As long as I keep the connection backup->master running (safe, because no new transactions on the migrated databases are occurring anymore on master1/2), the position on domain 0 gets recorded on master3. The problem is, as soon as I stop that connection, that master2 and master3 have different gtid-positions for domain0, and stop/start on replication master3->backup results in the error: "Got fatal error 1236 from master when reading data from binary log: 'Error: connecting slave requested to start from GTID 0-1-3898746614, which is not in the master's binlog' I have tried moving master1/2 to domain_id:1, and removing the domain_id:0 from the gtid_slave_pos on backup, but starting the replication master2->backup results in the error: Got fatal error 1236 from master when reading data from binary log: 'Could not find GTID state requested by slave in any binlog files. Probably the slave state is too old and required binlog files have been purged.' I have tried to find a way to insert an empty transaction, with the last gtid on domain_id:0 on the master3, to bring master2/master3 in sync again on that domain, but I could not find a way to do that on MariaDB. I tried finding a way to purge domain:0 from master3/master4, but the only way sofar I have found is doing a "RESET MASTER" on master3, which would break replication between master3 and master4. Are there other ways to fix this issue, so I can have reliable replication master3->backup without having to keep the dummy replication backup->master3 indefinitely? Regards, Reinder Cuperus
