Re: [Maria-developers] [Commits] 9ed264a391b160ef84121c8699bb3ff61c0059ce Fixed bug mdev-11072. In a general case the conditions with outer fields cannot be pushed into materialized views / derived tables. However if the outer field in the condition refers to a single row table then the condition may be pushable. In this case a special care should be taken for outer fields when pushing the condition into a materialized view / derived table.

[Maria-developers] Mdev-10715 -- Galera: Replicate MariaDB GTID to other nodes in the cluster
by Sachin Setiya 15 Nov '16

15 Nov '16

Hi Nirbyay, Serg, Kristian, In this mail I am answering some questions raised by Kristian and blue print for this task. 1. Questions of Kristian <knielsen> sachin_setiya_7: so maybe the problem is - that a node broadcasts its write set before the commit order has been determined? I do not think , this is the problem. Galera enforces the commit order. Yes, it broadcast write set in prepare phase. but it also guarantees that t1->t2 order will be maintained in all participating N nodes. <knielsen> sachin_setiya_7: how is the galera internal transaction id allocated and broadcast? I am here assuming that we are talking about gtid-sequence no. Suppose our initial seqno is S. So basically at this time all N have same sequence no. Some transaction T is executed at node Ni .It broadcast the writeset with its current sequence no S. At all Node Nj (including Ni).It receives this message. It checks some conditions Like it “totally ordered action”. If yes then Nj updates its sequence no to + 1. Here is the relevant code. if (gu_likely(GCS_ACT_TORDERED == rcvd->act.type && GCS_GROUP_PRIMARY == group->state && group->nodes[sender_idx].status >= GCS_NODE_STATE_DONOR && !(group->frag_reset && local) && commonly_supported_version)) { /* Common situation - * increment and assign act_id only for totally ordered actions * and only in PRIM (skip messages while in state exchange) */ rcvd->id = ++group->act_id_; } In function static inline ssize_t gcs_group_handle_act_msg (gcs_group_t* const group, const gcs_act_frag_t* const frg, const gcs_recv_msg_t* const msg, struct gcs_act_rcvd* const rcvd, bool commonly_supported_version) So basically It is like certification(generated at each node ) but done in quite early phase. Blueprint of task:- We can do something like galera GTID, we will take initial sequence no from server. We will add one more variable in gcs_group_t Named s_sequence_no and will increment it at each node. We also have to Create a gtid event and append it to message received at Nj , so that on late stages wsrep_apply_cb() can take care of gtid. Please let me know what you think. -- Regards Sachin Setiya Software Engineer at MariaDB

[Maria-developers] Changing the error message for ER_LOCK_WAIT_TIMEOUT
by Sergey Petrunia 12 Nov '16

12 Nov '16

Hi Sergei and everyone, MariaDB defines ER_LOCK_WAIT_TIMEOUT as share/errmsg-utf8.txt: eng "Lock wait timeout exceeded; try restarting transaction" facebook/mysql-5.6 has an enhancement: it also shows what kind of lock is held: share/errmsg-utf8.txt: eng "Lock wait timeout exceeded; try restarting transaction: %-.256s" the new error messages have more info and look like this: https://gist.github.com/spetrunia/266272c384a1b43081572e1ba2baf3f3 note that MyRocks also provides extra information. So, the questions are: - Is it (generally) possible to change error message texts in 10.2 still? - Can/should we change the ER_LOCK_WAIT_TIMEOUT error text? - (non-question) I assume that adding another error code with the new error text is not a good solution: two error codes for the same error will be very confusing. The number of times ER_LOCK_WAIT_TIMEOUT is used in the source is actually quite small: https://gist.github.com/spetrunia/2bc2ed7040a930d75b39162becbc7963 (25 occurences, and most of them actually dont care about the error message). There are lots of .result files to update, though. Any opinions? BR Sergei -- Sergei Petrunia, Software Developer MariaDB Corporation | Skype: sergefp | Blog: http://s.petrunia.net/blog

[Maria-developers] No MTR tests for --encrypt-binlog feature?
by Laurynas Biveinis 11 Nov '16

11 Nov '16

MariaDB - On 10.1 branch, grep on mysql-test for encrypt.binlog returns ./r/mysqld--help.result:180: --encrypt-binlog Encrypt binary logs (including relay logs) ./r/mysqld--help.result:1179:encrypt-binlog FALSE ./suite/sys_vars/r/sysvars_server_embedded.result:698:VARIABLE_NAME ENCRYPT_BINLOG ./suite/sys_vars/r/sysvars_server_notembedded.result:712:VARIABLE_NAME ENCRYPT_BINLOG Thus it does not look that the feature has actual tests. How do you know it works? Thanks, -- Laurynas

[Maria-developers] Deleting unused branches on github
by Kristian Nielsen 10 Nov '16

10 Nov '16

We currently have more than 200 branches in the MariaDB Server github repo, most of which look like they are no longer used. I would like to remove the unused ones to remove clutter. Eg. in `git branch -la` or the drop-downs on the github webpage. Below is a list of a little less than two-thirds of the branches that I determined to be probably unused. I was fairly conservative in my criteria, ie. if there was reasonable doubt, I omitted a branch from the list to delete. Please take a look at the list and see if there is any branch that should _not_ be deleted from the github repository. Or if someone objects to deleting anything on principle grounds, let me know as well, of course. (I Cc'ed people that were the last to commit on a branch to be deleted). Note that if one of these branches should become needed again later, eg. some bb-XXX branch not used for a long time, there is no problem re-creating it. The only problem with removing a branch should be if it contains contents that will be needed in the future, and which is not available anywhere else (and I tried to avoid putting such branches on the list in the first place). Also note that once these are deleted, a simple `git pull` will not remove them from the local clone. The `git fetch --prune` can be used to effect this. If there are no objections, I will do the deletions in two weeks. - Kristian. ----------------------------------------------------------------------- These branches have not been updated for a long time, and looked like they were not used any more.

Hello Sanja, Elena, Wlad, Sanja, please review a patch for MDEV-10780. The patch is for 10.1. I could not reproduce it in 10.0. But it should be safe to push it into 10.0 anyway. This patch is most likely fixing MDEV-10806 (assigned to Sanja) and MDEV-10910 (assigned to Elena). Thanks!
