The introduction of ActiveJob and `deliver_now` in 7f214cee7 caused a race
condition where the mailer would be invoked before the project was committed
to the database, causing the transfer e-mail notification to show the old
path instead of the new one.
Closes#4670
This removes the need for Sidekiq and any overhead/problems introduced
by TCP. There are a few things to take into account:
1. When writing data to InfluxDB you may still get an error if the
server becomes unavailable during the write. Because of this we're
catching all exceptions and just ignore them (for now).
2. Writing via UDP apparently requires the timestamp to be in
nanoseconds. Without this data either isn't written properly.
3. Due to the restrictions on UDP buffer sizes we're writing metrics one
by one, instead of writing all of them at once.
Downcased user or email search for avatar_icon.
GitLab users are defined with their mail address which is enforced to be lower case. When a commit is listed in the history whose committer mail address is not written in all lower case, the corresponding GitLab user won't be found because the search is case sensitive resp. the mail address to search for not downcased.

This is a temporary hotfix that allows to access build artifacts created
before 8.3. See #5257.
This needs to be changed after migrating CI build files.
Note that `ArtifactUploader` uses `artifacts_path` to create a storage
directory before and after parsisting `Ci::Build` instance, before and
after moving a file to store (save and fetch a file).
Storing of application metrics in InfluxDB
This adds support for tracking metrics in InfluxDB, which in turn can be visualized using Grafana. For more information see #2936.

Disable --follow in `git log` to avoid loading duplicate commit data in infinite scroll
`git` doesn't work properly when `--follow` and `--skip` are specified together. We could even be **omitting commits in the Web log** as a result.
Here are the gory details. Let's say you ran:
```
git log -n=5 --skip=2 README
```
This is the working case since it omits `--follow`. This is what happens:
1. `git` starts at `HEAD` and traverses down the tree until it finds the top-most commit relevant to README.
2. Once this is found, this commit is returned via `get_revision_1()`.
3. If the `skip_count` is positive, decrement and repeat step 2. Otherwise go onto step 4.
4. `show_log()` gets called with that commit.
5. Repeat step 1 until we have all five entries.
That's exactly what we want. What happens when you use `--follow`? You have to understand how step 1 is performed:
* When you specify a pathspec on the command-line (e.g. README), a flag `prune` [gets set here](https://github.com/git/git/blob/master/revision.c#L2351).
* If the `prune` flag is active, `get_commit_action()` determines whether the commit should be [scanned for matching paths](https://github.com/git/git/blob/master/revision.c#L2989).
* In the case of `--follow`, however, `prune` is [disabled here](https://github.com/git/git/blob/master/revision.c#L2350).
* As a result, a commit is never scanned for matching paths and therefore never pruned. `HEAD` will always get returned as the first commit, even if it's not relevant to the README.
* Making matters worse, the `--skip` in the example above would actually skip a every other entry after `HEAD` N times. If README were changed in these skipped commits, we would actually miss information!
Since git uses a matching algorithm to determine whether a file was renamed, I
believe `git` needs to generate a diff of each commit to do this and traverse
each commit one-by-one to do this. I think that's the rationale for disabling
the `prune` functionality since you can't just do a simple string comparison.
