MySQL does not work with thoth --migrate #3

Closed gusandrianos closed 7 years ago

gusandrianos commented 7 years ago

It will not work at all without the changes in #2 as it cannot find the MySQL installation. But even if it finds the installation this happens,

And if I manually create the db, it throws this.

Can you please post your thoth.conf file from your testone project here

I can see that you are in directory t1 but the exception refers to testone.

  1. Did you do thoth --create t1 or thoth --create testone? Looks like something is out of sync there. For example the error message refers to testone whereas the thoth.conf refers to t1. Can you do it again from the start and post the steps here please?

  2. Can you see what tables have been generated in MySQL please?

  3. Are the user:password@hostname set to the correct credentials?

  4. Have you created a user in MySQL with these credentials? (are there in the MySQL users table?)

gusandrianos commented 7 years ago

Okay, I created a new one.

  1. I did thoth --create t1, I just thought not to name the db t1.

Steps. thoth --create test cd test change to mysql2 and enter my credentials, doing /test for the database name. thoth --migrate E [2017-07-06 12:39:49 $28409] ERROR | : Unable to connect to database: Mysql2::Error: Unknown database 'test'

Manually creating a database named test and then running the migration causes this.

Error: Mysql2::Error: Table 'test.posts' doesn't exist

The credentials are correct.

pagojo commented 7 years ago

@GusAndrianos it seems from the first error message that you didn't create the database.

However, the last part of your post is relevant to the problem here because it suggests that the database was then created successfully.

Please paste here the steps/commands for how you created the test database and how you granted the credentials to it.

What happens after you create the database and you run the migration?

Does the migration run ok? What does it say?

In MySQL what is the schema of that database after the migration?

gusandrianos commented 7 years ago

I created the database myself through mysql server with create database test; The credentials I gave were the same I give when launching mysql like mysql -u user -p I described at the end of my last comment what happens when I run the migration again. The schema remains the same throughout the process, that is, empty.

pagojo commented 7 years ago

First of all, just to clarify. When not using SQLite3, a database must be created manually by the database admin with the right credentials. Therefore this must always be the case before migrations are run.

Try this. create a new MySQL database testx with the right credentials and access rights.

then

thoth --create testx
cd testx
thoth --log-sql sqllog --migrate 01
thoth --irb

In the IRB type

Thoth::open_db

and please post here what is the result of the open_db as well as the contents of the sqllog.

gusandrianos commented 7 years ago

The result of thoth --log-sql sqllog --migrate 01 is Error: Mysql2::Error: Table 'testx.posts' doesn't exist

and the result of Thoth::open_db is => #<Sequel::Mysql2::Database: "mysql2://user:mypassword@localhost/testx" {:encoding=>"utf8"}>

So I assume that it finds the database, has access to it, but cannot complete the migration.

pagojo commented 7 years ago
  1. Silly questions but does the "mysql2://user:mypassword@localhost/testx" really have user and mypassword as credentials?

  2. Migration 01 only creates the tables, so the error message is a bit odd. Can you please check the sqllog inside the testx folder and copy it here please?

gusandrianos commented 7 years ago

Silly indeed. Have you tried it yourself and got a different result?

The database I create is empty, but, after the migration

+-----------------+
| Tables_in_testx |
+-----------------+
| schema_info     |
+-----------------+
1 row in set (0,00 sec)

Which implies that the credentials are indeed correct (and they are) and thoth has access to mysql.

Here's the log.

pagojo commented 7 years ago

I assume you posted the whole log right?

This is very interesting, we may have stumbled on a bug outside our control.

Please can you list the exact versions of your mysql2 gem, Sequel gem and MySQL server?

gusandrianos commented 7 years ago

Of course I did. Here are the versions.

pagojo commented 7 years ago

It seems that when Sequel tries to check that a table is not there (before it attempts to create it during the migration) the database driver throws an exception, which Sequel cannot handle.

For the testx project that you previously created (as discussed above), please try the following

cd testx
thoth --irb
Thoth::open_db
Thoth.db.table_exists?("schema_info")
Thoth.db.table_exists?("comments")
gusandrianos commented 7 years ago

The result is false and false...

pagojo commented 7 years ago

Can you please paste all the output from the IRB session?

gusandrianos commented 7 years ago

Sorry, true for schema_info

ok, now please check the following

    unless Thoth.db.table_exists?(:comments)
      Thoth.db.create_table :comments do
        primary_key :id

        varchar  :author,        :null => false
        varchar  :author_url
        varchar  :title,         :null => false
        text     :body,          :default => ''

        foreign_key :post_id, :table => :posts

This was expected to fail if you have a foreign key constraint on the posts table which it can't find. Can you provide code to create the posts table first?

pagojo commented 7 years ago

Super!

pagojo commented 7 years ago

The migrations are very old and adhere to the default mode of SQLite3 (and of the MySQL MyISAM engine I guess) where foreign key constraints are by default not enforced.

Just for completeness of the defect report can you please disable foreign key checks in MySQL, from the MySQL CLI:

SET GLOBAL FOREIGN_KEY_CHECKS=0;

and then run thoth --log-sql sqllog --migrate and post the sqllog here?

Did you set SET GLOBAL FOREIGN_KEY_CHECKS=0; can you check they have been globally applied please and not only on one session?

what does show global variables say?

gusandrianos commented 7 years ago

Of course I did... Maybe there's a compatibility problem? If I am not mistaken, mysql now uses InnoDB.

pagojo commented 7 years ago

Hmmm this is strange. Can you please switch on the MySQL logging on, repeat the migration and post the logs here?

Also can you post all the results of show global variables please?

Sorry, are the above global or local variables?

pagojo commented 7 years ago

ok, I can now reproduce this.

gusandrianos commented 7 years ago

Obviously global.

pagojo commented 7 years ago

There is nothing obvious in debugging! I'm on it. It looks like the session turns it ON :-/

pagojo commented 7 years ago

So what really happens...

The Sequel shared driver for MySQL checks the schema of the referenced tables to the table which is about to create through DESCRIBE. This fails the foreign key checks inside the adaptor, although such checks may have been disabled in the MariaDB/MySQL server.

This happens from create_table_sql which checks for the keys of the referenced table sequel-4.46.0/lib/sequel/adapters/shared/mysql.rb:394 in create_table_sql

which ends up in sequel-4.46.0/lib/sequel/adapters/shared/mysql.rb:493 in schema_parse_table

Why doesn't this happen with the SQLite3 adaptor?

Well, the create_table_sql from the common code (as in the case of few other DBs but not all) ends up in a DB specific create_table_sql (shared/mysql.rb in this case), whereas for Sqlite3 (and few other DBs) it doesn't follow that route.

What happens is that, in the case of Sqlite3, the generic code in sequel-4.46.0/lib/sequel/database/schema_methods.rb:213 in create_table prepares the statement in create_table_sql and ends up in query.rb:execute_dui and then in query.rb:execute and adapters/sqlite.rb:_execute without prior extra checks to the schema of the table (like in the case of the mysql adaptor). This is irrespective of whether one may have enabled foreign key checks in SQLite3 or not.

gusandrianos commented 7 years ago

So it is indeed out of our reach... It's a weird issue really, having no control over your settings for MySQL... We're better off using SQLite anyway, but MySQL support would be a "Nice to have" feature.

I will have to look at re-working the existing migrations. I need to think about it.

gusandrianos commented 7 years ago

I have plenty of time. I can help if you like.

pagojo commented 7 years ago

Fixed with Release 0.4.2

gusandrianos commented 7 years ago

Oh!!! Nice :)

gusandrianos commented 7 years ago

Actually, we have another problem :/

screenshot from 2017-09-21 19-22-14

Furthermore, since my fix isn't in the current version, thoth --migrate still throws an Unable to connect to database: LoadError: cannot load such file -- mysql error, until you change mysql to mysql2.

pagojo commented 7 years ago

Pulled #2 in the mainline. Actually it is not strict that you need mysql2, but it saves me from documenting it :-)

gusandrianos commented 7 years ago

Thanks for merging that. Did you see the error in the screenshot?

Error: Mysql2::Error: BLOB, TEXT, GEOMETRY or JSON column 'body' can't have a default value

I may have a clue what's going on with it, I'll try to fix it and report back.

pagojo commented 7 years ago

If this is a bug, then please first post it as a new issue and then we'll see about the pull request. On my setup I can't see anything. Please open a new issue to track this and report the versions of the server, the mysql2 adapter, Sequel etc.
