Re: [Maria-developers] [Maria-discuss] Known limitation with TokuDB in Read Free Replication & parallel replication ?

So I took a look at the complete patch we have so far, thinking what remains to do to get this included in main MariaDB. Do you have any suggestions for how/whether to upstream the TokuDB parts? I assume the new kill_query functionality would make sense to upstream. The callback to report waits could be upstreamed, but would not be used in non-mariadb builds, probably. And the actual tokudb_lock_wait_needed_callback() would probably not be upstreamed (or would go in #ifdef MARIADB_BASE_VERSION perhaps). Any thoughts? I still need to look into the should_retry_lock_requests, currently I get hangs if it is enabled. And I want to see if the wait_needed_callback interface can be cleaned up a bit. Otherwise the patch looks fairly complete to me, do you agree? I think this could go in 10.1, to fix optimistic parallel replication with TokuDB (which does not currently work at all). - Kristian.

The details are below. * The wording of the warning feels odd: > Field or reference 'test.t10.b' of SELECT #3 was resolved in SELECT #1 > ... > Aggregate function 'max()' of SELECT #3 belongs to SELECT #1 + I like how the wording of the new warning is similar to the old one. - It is not immediately clear what does "belong to" mean. I would change it to " Aggregate function 'max()' of SELECT #3 is aggregated in SELECT #1 " This looks much clearer. OTOH, "Aggregate .. is aggregated" doesn't sound very good.

[Maria-developers] Aggregate Functions

Hi, As GSOC is nearing its end, I have written a blog which contains how can aggregate functions be written and executed to get the desired results.In the blog I also have added the technical details of this project on aggregate functions. Here are the links: Jira issue: https://jira.mariadb.org/browse/MDEV-7773 Blog Link: http://varunraiko.github.io/aggregate-functions/ Disclaimer: I hereby declare that all my work done so far (and future) by me on the Aggregate Functions’ project, is released under the NEW BSD licence.

Re: [Maria-developers] Sachin weekly report

Hi Sergei! Actually I completed the work on update and delete. Now they will use index for looking up records. But I am thinking I have done a lot of changes in optimizer which may break it , and also there are lots of queries where my code does not work, fixing this might take a long amount of time. I am thinking of a change in my existing code :- Suppose a table t1 create table t1 (a blob, b blob, c blob, unique(a,b,c)); In current code , for query like there will a KEY with only one keypart which points to field DB_ROW_HASH_1. It was okay for normal updates , insert and delete , but in the case of where optimization I have do a lot of stuff , first to match field (like in add_key_part), then see whether all the fields in hash_str are present in where or not, then create keys by calculating hash. I do this by checking the HA_UNIQUE_HASH flag in KEY , but this also makes (I think) optimizer code bad because of too much dependence. Also I need to patch get_mm_parts and get_mm_leaf function , which I think should not be patched. I am thinking of a another approach to this problem at server level instead of having just one keypart we can have 1+3 keypart. Last three keypart will be for field a, b, c and first one for DB_ROW_HASH_1 .These will be only at server level not at storage level. key_info->key_part will point at keypart containing field a , while key_part having field DB_ROW_HASH_1 will -1 index. By this way I do not have to patch more of optimizer code. But there is one problem , what should be the length of key_part? I am thinking of it equal to field->pack_length(), this would not work because while creating keys optimizer calls get_key_image() (which is real data so can exceed pack_lenght() in case of blob), so to get this work I have to patch optimizer where it calls get_key_image() and see if key is HA_UNIQUE_HASH . If yes then instead of get_key_image just use memcpy(key, field->ptr(), field->pack_length()); this wont copy the actual data, but we do not need actual data. I will patch handler methods like ha_index_read, ha_index_idx_read , multi_range_read_info_const basically handler methods which are related to index or range search. In these methods i need to calculate hash , which I can calculate from key_ptr but key_ptr doe not have actual data(in case of blobs etc).So to get the date for hash , I will make a field clone of (a,b,c etc) but there ptr will point in key_ptr. Then field->val_str() method will work simply and i can calculate hash. And also I can compare returned result with actual key in handler method itself. What do you think of this approach ?

Ok, so I implemented this, available in this branch: https://github.com/knielsen/server/commits/toku_opr3 With this code, I am no longer able to reproduce any hangs with the tests I've been running so far. > BTW, the current_lock_tree_mutex logic is broken.

Yes, and this is the main problem solved by doing the kill asynchronously. And from my tests, it looks like this was actually what was causing the problems - crash, assertion, and hangs. (I haven't determined this conclusively, but it seems at least plausible). It really was always an ugly hack around the locking problem with thd_report_wait_for() (InnoDB had a similar issue), it seems good to get rid of it. I still have the should_retry_lock_requests disabled in retry_all_lock_requests() - otherwise I get hangs. I haven't investigated this deeply yet. I also want to go back over the entire set of patches and see what needs cleaning up, and think about how this could go into 10.2 and possibly 10.1. - Kristian.

[Maria-developers] Commit emails reply-to maria-developers@lists.launchpad.net
by Sergey Vojtovich 24 Aug '16

24 Aug '16

Hi! Why do commit emails have "Reply-To: maria-developers(a)lists.launchpad.net"? I believe it is wrong at least for the following reasons: - I must be careful if I want to reply privately, e.g. something like "hold on, I'll review it in a few hours" doesn't deserve to hit maria-developers@ - I want a person, I'm replying to, to be primary recepient, but Reply-To substitutes his email with maria-devlopers@. Makes it easy to miss reviews. Sergei mentioned that one of reasons might be so that we want to keep commits(a)mariadb.org. I believe it doesn't work because: - if I do group reply, I end up with email that has CC: commits(a)mariadb.org Thanks, Sergey

Re: [Maria-developers] [Commits] 294961c: MDEV-10538: MariaDB fails to start without galera_recovery in systemd mode
by Sergey Vojtovich 24 Aug '16

Hi Nirbhay, Ok to push. I suggest that we avoid such overcomplicated constructs in our default systemd configuration. Consider integrating recovery into the server (I know it's not trivial) or creating "included" config for galera.

[Maria-developers] Please review MDEV-10604 Disable unstable MTR tests by default
by Elena Stepanova 24 Aug '16

24 Aug '16

Hi Sergey (Vojtovich), Please review the patch that we've discussed at length. Serg, FYI. The length of the "unstable" list shouldn't scare anyone. At the end, this task should cause no change in our current procedure, the tests will still be run in buildbot and hopefully on developers' local machines (and every external user who wants to run them can do it easily). The change should mainly help those who run tests as a part of their build process. The lists can be tuned later, now they have been created generously, to solve the most urgent issue in shortest time possible. Please note that it's still not a 100% guarantee that nothing will fail sporadically, I've already got an absolutely new random failure after disabling all known ones, so it will still require some iterations.
