Why not to pass the destination as a third argument to CREATE_MARIADB_SYMLINK? As far as I can see, everywhere where you use CREATE_MARIADB_SYMLINK the destination is available. The rest is okay. I'd still suggest to simplify by splitting the list in two, like macro(REGISTER_SYMLINK from to) list(APPEND MARIADB_SYMLINK_FROMS from) list(APPEND MARIADB_SYMLINK_TOS to) endmacro() REGISTER_SYMLINK(mysql mariadb) REGISTER_SYMLINK(mysqladmin mariadb-access) ...etc... Then you won't need to do math on indexes, you simply search in MARIADB_SYMLINK_FROMS and get the same element in MARIADB_SYMLINK_TOS. Also you will need to search only in MARIADB_SYMLINK_FROMS, not like now, when you search in the complete list, risking to get spurious matches on mariadb* names. Same in manpages, you'll only iterate over MARIADB_SYMLINK_FROMS list. > + > + CREATE_MARIADB_SYMLINK_IN_DIR(${src} ${dest} ${symlink_install_dir} ${comp}) > + endif() > +endmacro(CREATE_MARIADB_SYMLINK) Regards, Sergei Chief Architect MariaDB and security(a)mariadb.org

[Maria-developers] GSoC [MDEV-5092]
by Мирослав Коберский 14 Jun '19

14 Jun '19

Hello, I'm working in implementing UPDATE .. RETURNING. For beginning i'm working on single-table update. I've made parser to parse RETURNING clause in UPDATE. There was a problem that columns that should be updated and columns that should be returned were stored in the same list in lex named item_list. I'm trying now to divide them. Not sure that swapping lists two times during parsing between each other is the best idea. I've implemented primitive returning of result set every time doing an update (even without RETURNING clause) to understand how client understands such response. It successfully returns result set in very simple updates. https://github.com/Mup0c/server/commits/MDEV-5092 -- Miroslav Koberskii

So, the test is always false, unless you re-run cmake after the build, which is not a normal build procedure. 2. you create a symlink _at install time_ but in a CMAKE_CURRENT_BINARY_DIR. This is strange decision. Normally, build step creates files in CMAKE_CURRENT_BINARY_DIR, and install step creates files in INSTALL_BINDIR. Basically, to fix that you should either create symlinks as a new build target that dependents on binaries being created first. And then install these symlinks normally. Or create symlinks during install time directly at the correct install location, not in the binary dir. > diff --git a/debian/mariadb-client-10.4.links b/debian/mariadb-client-10.4.links > index 4a504969246..b93d2d7f8fd 100644 > --- a/debian/mariadb-client-10.4.links > +++ b/debian/mariadb-client-10.4.links > @@ -1,6 +1,44 @@ > +usr/bin/mysql_find_rows usr/bin/mariadb-find-rows > +usr/bin/mysql_fix_extensions usr/bin/mariadb-fix-extenstions > +usr/bin/mysql_plugin usr/bin/mariadb-plugin Why there's a separate rpm with symlinks, but no separate deb with symlinks (they're direcly in the client deb) ?

Hi, Aleksey! Looks ok, thanks! No requests to change anything, but still a couple of "why" questions, see below On Jun 07, Aleksey Midenkov wrote: > revision-id: 66f931bcd69 (mariadb-10.3.12-100-g66f931bcd69) > parent(s): f4484dfdbf2 > author: Aleksey Midenkov <midenok(a)gmail.com> > committer: Aleksey Midenkov <midenok(a)gmail.com> > timestamp: 2019-03-26 15:04:52 +0300 > message: > > MDEV-18727 improve DML operation of System Versioning > MDEV-18957 UPDATE with LIMIT clause is wrong for versioned partitioned tables > > UPDATE, DELETE: replace linear search of current/historical records > with vers_setup_conds(). > > diff --git a/sql/sql_parse.cc b/sql/sql_parse.cc > index b8ed887b52d..a00cc2a8fb0 100644 > --- a/sql/sql_parse.cc > +++ b/sql/sql_parse.cc > @@ -4975,8 +4975,10 @@ mysql_execute_command(THD *thd) > { > result= new (thd->mem_root) multi_delete(thd, aux_tables, > lex->table_count); > - if (unlikely(result)) > + if (likely(result)) heh, good catch > { > + if (unlikely(select_lex->vers_setup_conds(thd, aux_tables))) > + goto multi_delete_error; > res= mysql_select(thd, > select_lex->get_table_list(), > select_lex->with_wild, > diff --git a/sql/sql_select.cc b/sql/sql_select.cc > index 6915d4d23ca..28b54e0b3b1 100644 > --- a/sql/sql_select.cc > +++ b/sql/sql_select.cc > @@ -779,20 +781,35 @@ int SELECT_LEX::vers_setup_conds(THD *thd, TABLE_LIST *tables) > } > } > > + bool is_select= false; > + switch (thd->lex->sql_command) > + { > + case SQLCOM_SELECT: > + case SQLCOM_INSERT_SELECT: > + case SQLCOM_REPLACE_SELECT: > + case SQLCOM_DELETE_MULTI: > + case SQLCOM_UPDATE_MULTI: > + is_select= true; > + default: > + break; > + } > + > for (table= tables; table; table= table->next_local) > { > - if (!table->table || !table->table->versioned()) > + if (!table->table || table->is_view() || !table->table->versioned()) why? > continue; > > vers_select_conds_t &vers_conditions= table->vers_conditions; > > #ifdef WITH_PARTITION_STORAGE_ENGINE > - /* > - if the history is stored in partitions, then partitions > - themselves are not versioned > - */ > - if (table->partition_names && table->table->part_info->vers_info) > + Vers_part_info *vers_info; > + if (is_select && table->table->part_info && > + (vers_info= table->table->part_info->vers_info)) > + { > + if (table->partition_names) Why is that? You don't seem to use vers_info anywhere.

Sachin, salute!

I can bet the failure was also exposed by reset @@global.'connection_name'.'rule_type' variables, which the test is really missing.

Hello. This is the thread where I would like to publish my weekly reports every Monday. During preparatory weeks I set up development environment. I briefly examined testing framework, debugging process and now I am ready to start work. Work progress will be available on my github repository in branch "MDEV-6017" https://github.com/ZeroICQ/server/tree/MDEV-6017

[Maria-developers] Weekly Report
by Rucha Deodhar 10 Jun '19

10 Jun '19

Report for week 2: Hello! This week I ran the test case for parser written in last week and made changes in the parser according to the suggestions given, tried making insert...select..returning work. I analysed how RETURNING in delete is implemented, how insert is implemented, and how the data can be sent, which functions are responsible and what those functions do, to carry out various steps and what these steps are in order to send the data to the client. I came up with a plan where code for RETURNING should go and files where the code has to be written. There were few things which weren't very clear initially. So I referred to some documents on the internet and some source code document. My github repo is up to date with the changes in the code, result and test files. Regards, Rucha

Hi Serg, I've addressed general review requests by Wlad and review requests by Otto related to Debian packaging. The latest commit is here: https://github.com/MariaDB/server/commit/030c299f76fac044d43325abb02b5751fe… Could you give it final review to see if it can be pushed to main 10.4?
