MySQL Bugs: #75366: mysql_install_db requires explicit --lc-messages-dir if non-default PREFIX used

Bug #75366	mysql_install_db requires explicit --lc-messages-dir if non-default PREFIX used
Submitted:	31 Dec 2014 12:18	Modified:	30 Jan 2015 8:00
Reporter:	Valeriy Kravchuk	Email Updates:
Status:	Won't fix	Impact on me:	None

Version:	5.7.5	OS:	Any

Description:
I've build MySQL 5.7 from git with non-default -DCMAKE_INSTALL_PREFIX like this:

2072     cmake . -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_CONFIG=mysql_release -DFEATURE_SET=community -DWITH_EMBEDDED_SERVER=OFF -DCMAKE_INSTALL_PREFIX=/home/openxs/dbs/5.7 -DWITH_BOOST=/home/openxs/boost

In previous versions mysql_install_db when called from that prefix/basedir like this:

bin/mysql_install_db --no-defaults

just worked and was able to use proper default datadir etc. Now one has top specify datadir (and manual explains that, see http://dev.mysql.com/doc/refman/5.7/en/mysql-install-db.html#option_mysql_install_db_datad...), but it seems in my case one has to specify --lc-messages-dir explicitly as well:

openxs@ao756:~/dbs/5.7$ bin/mysql_install_db --no-defaults --datadir=/home/openxs/dbs/5.7/data/ --lc-messages-dir=/home/openxs/dbs/5.7/share

Otherwise mysql_install-db does not work. Maybe one has just to set --basedir explicitly, but in both cases manual does NOT say these options are mandatory for my case. So, this can be considered like a regression in your new implementation of mysql_install_db.

Server started with --no-defaults is able to find/get lc_messages_dir without problem:

mysql> show variables like 'lc%';
+-----------------+-----------------------------+
| Variable_name   | Value                       |
+-----------------+-----------------------------+
| lc_messages     | en_US                       |
| lc_messages_dir | /home/openxs/dbs/5.7/share/ |
| lc_time_names   | en_US                       |
+-----------------+-----------------------------+
3 rows in set (0,00 sec)

How to repeat:
Try to build from source and then install MySQL 5.7.5 using commands like these:

cmake . -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_CONFIG=mysql_release -DFEATURE_SET=community -DWITH_EMBEDDED_SERVER=OFF -DCMAKE_INSTALL_PREFIX=/home/openxs/dbs/5.7 -DWITH_BOOST=/home/openxs/boost
make -j 2
make install && make clean
cd /home/openxs/dbs/5.7
rm -rf data/*
bin/mysql_install_db --no-defaults --datadir=/home/openxs/dbs/5.7/data/

Enjoy the output of the last command and then try to find explanation in the manual.

Suggested fix:
Either fix build scripts/mysql_install_db code to take -DCMAKE_INSTALL_PREFIX into account properly while checking location for messages, or explain in the manual what options for this utility are mandatory in this case.

http://bugs.mysql.com/bug.php?id=73845

I do not agree with "Not a Bug" status for bug #73845. I do not see this change documented anywhere and I fail to see any reason to NOT infer the location of messages for mysql_install_db from the same information that lets mysqld to get it properly.

So, let's try again with this report...

Hello Valeriy,

Thank you for the report.

Thanks,
Umesh

mysql_install_db is deprecated. WL#7307 is pushed into the trunk that does not suffer this problem. Please consider using --initialize instead.
