- When renaming a column concurrently, drop any existing trigger before
attempting to create a new one.
When running migration specs multiple times (as it happens during
local development), the down method of previous migrations are called.
If any of the called methods contains a call to
rename_column_concurrently, a trigger will be created and not removed.
So, the next time a migration spec is run, if the same down method is
executed again, it will cause an error when attempting to create the
trigger (since it already exists). Dropping the trigger if it already
exists will prevent this problem.
This improves the `add_timestamps_with_timezone` helper by allowing the
column names to be configured. This has the advantage that unnecessary
columns can be avoided, saving space.
A helper for removing the columns is also provided, to be used in the
`down` method of migrations.
So funny story, true story. I tried to run the test locally, but
didn't make it past setting up Gitaly.
Here's what I tried:
First attempt:
`git clone gitlab-ce`
`cd gitlab-ce && bundle install`
`be rspec`
This didn't work because I was missing the config/database.yml, I
didn't see a `script/bootstrap` so I looked in the readme which
redirected me to a webpage which redirected me to the
gitlab-development-kit.
Second attempt:
`gem install gitlab-development-kit`
cd gitlab-development-kit
gdk init
gdk isntall
This broke somwhere along the way because it couldn't install Gitaly
because my go version was too low. But it did clone the gitlab repo
again and this time it did have a config/database.yml.
So I tried to cd into it and `be rspec
spec/lib/gitlab/database/migration_helpers_spec.rb` which complained
about the database not being configured so I:
- Changed the socket to localhost (in the config/database.yml)
- `createdb <dev_db>` `createdb test_db`
- `be rake db:test:prepare`
Great success, it was doing things! But then failed when it came at
the Gitaly step.
Since I only want to change these three lines, at the point I gave up
and entrusted the pipeline to do its thing.
What I would have liked:
- A 'It's a Rails system, I know this' readme/docs (It's in there
somewhere just couldn't find it)
- A way to run tests without having to use Gitaly
- Not having too install all the things for a small fix (I get why'd
you want this, but to me it's overkill)
The rather cryptic:
"fk_#{Digest::SHA256.hexdigest("#{table}_#{column}_fk").first(10)}"
Was too much for emacs too handle*, since it was coming from the Rails
codebase I took their way of doing the same thing and applied it here.
I think it's easier to read and it also makes emacs render the
migration helpers pretty again.
* not true, emacs can handle anything, leave emacs alone!
