Only redirect to homepage url when its not the root url
It was possible to create an infi redirect when the user set up the
`home_page_url` to redirect to the main URL of the gitlab instance.
This fix makes sure this redirect is not possible.

Remove duplicate orders
This changes the default order from `created_at DESC, id DESC` to just `id DESC` as this achieves the same results without the overhead of having to sort data twice (we've seen queries go from 200ms to just a few ms by removing the double sort).

Extend yml syntax for only and except to support specifying repository path
This allows to limit execution of jobs to specific repository.
For example:
```yaml
job:
only:
- branches@gitlab-org/gitlab-ce
except:
- master@gitlab-org/gitlab-ce
```
The above will run `job` for all branches on `gitlab-org/gitlab-ce`, except master.
@dzaporozhets @JobV @vsizov Please review.
See merge request !1720
Sorting by both "created_at" and "id" in descending order is not needed
as simply sorting by "id" in descending order will already sort rows
from new to old. Depending on the query and data involved sorting twice
can also introduce significant overhead.
It was possible to create an infi redirect when the user set up the
`home_page_url` to redirect to the main URL of the gitlab instance.
This fix makes sure this redirect is not possible.

Prior, the value of the Ace editor was only being persisted if the user
physically clicked the submit button, which the "quick submit" behavior
doesn't do.
Now the value will be properly transferred before any form is submitted.
This further improves performance of User.find_by_any_email and is
roughly twice as fast as the previous UNION setup.
Thanks again to @dlemstra for suggesting this.
This is significantly faster than using a sub-query, at least when run
on the GitLab.com production database. The benchmarks are a lot slower
now with these changes, most likely due to PostgreSQL choosing a
different (and less efficient) plan based on the amount of data present
in the test database.
Thanks to @dlemstra for suggesting the use of a UNION.
This query used to rely on a JOIN, effectively producing the following
SQL:
SELECT users.*
FROM users
LEFT OUTER JOIN emails ON emails.user_id = users.id
WHERE (users.email = X OR emails.email = X)
LIMIT 1;
The use of a JOIN means having to scan over all Emails and users, join
them together and then filter out the rows that don't match the criteria
(though this step may be taken into account already when joining).
In the new setup this query instead uses a sub-query, producing the
following SQL:
SELECT *
FROM users
WHERE id IN (select user_id FROM emails WHERE email = X)
OR email = X
LIMIT 1;
This query has the benefit that it:
1. Doesn't have to JOIN any rows
2. Only has to operate on a relatively small set of rows from the
"emails" table.
Since most users will only have a handful of Emails associated
(certainly not hundreds or even thousands) the size of the set returned
by the sub-query is small enough that it should not become problematic.
Performance of the old versus new version can be measured using the
following benchmark:
# Save this in ./bench.rb
require 'benchmark/ips'
email = 'yorick@gitlab.com'
def User.find_by_any_email_old(email)
user_table = arel_table
email_table = Email.arel_table
query = user_table.
project(user_table[Arel.star]).
join(email_table, Arel::Nodes::OuterJoin).
on(user_table[:id].eq(email_table[:user_id])).
where(user_table[:email].eq(email).or(email_table[:email].eq(email)))
find_by_sql(query.to_sql).first
end
Benchmark.ips do |bench|
bench.report 'original' do
User.find_by_any_email_old(email)
end
bench.report 'optimized' do
User.find_by_any_email(email)
end
bench.compare!
end
Running this locally using "bundle exec rails r bench.rb" produces the
following output:
Calculating -------------------------------------
original 1.000 i/100ms
optimized 93.000 i/100ms
-------------------------------------------------
original 11.103 (± 0.0%) i/s - 56.000
optimized 948.713 (± 5.3%) i/s - 4.743k
Comparison:
optimized: 948.7 i/s
original: 11.1 i/s - 85.45x slower
In other words, the new setup is 85x faster compared to the old setup,
at least when running this benchmark locally.
For GitLab.com these improvements result in User.find_by_any_email
taking only ~170 ms to run, instead of around 800 ms. While this is
"only" an improvement of about 4.5 times (instead of 85x) it's still
significantly better than before.

Simply type a name with a `/` directory separator and new directories
will be created. This does not do the fancy UI work that github.com
does, but it will get the job done.
I could not find tests for file creation, so I didn't add a test for
this slight behaviour modification. I did test directory traversals
though, using both absolute paths like `/tmp/foo.txt` and relative paths
like `../../foo.txt`. Neither case escaped the repository, though
attempting to traverse with a relative path resulted in a 500 error that
did not affect application stability upon reload.
