With Errbit, you can set up your own server and host the information
regarding your exceptions there. You can also hire Airbrake's hosting
services or easily setup Errbit on Heroku.
We're still including the rollbar gem so we don't harm CONSUL users who
are using rollbar.
Note Errbit requires an old version of Airbrake which forced users to
configure the gem. So we're adding the current environtment to
`ignore_environments` when the project id isn't defined; this way the
application won't crash in this case.
We didn't upgrade Turbolinks when we upgraded to Rails 5 so we didn't
upgrade too many things at the same time, and postponed it... until now
:).
Note upgrading Turbolinks fixes an issue with foundation's sticky when
using the browser's back and forward buttons. We're adding tests for
these scenarios.

Using pg_search 2.0.1 with Rails 5.2 results in deprecation warnings:
DEPRECATION WARNING: Dangerous query method (method whose arguments used
as raw SQL) called with non-attribute argument(s):
"pg_search_978c2f8941354cf552831b.rank DESC, \"tags\".\"id\" ASC".
Non-attribute arguments will be disallowed in Rails 6.0. This method
should not be called with user-provided values, such as request
parameters or model attributes. Known-safe values can be passed by
wrapping them in Arel.sql().
We're not upgrading to the latest pg_search because it only supports
ActiveRecord >= 5.2.
With two concurrent requests, it's possible to create two ballot lines
when only one of them should be created.
The reason is the code validating the line is not thread safe:
```
if ballot.amount_available(investment.heading) < investment.price.to_i
errors.add(:money, "insufficient funds")
end
```
If the second request executes this code after the first request has
executed it but before the first request has saved the record to the
database, both records will pass this validation and both will be saved
to the database.
So we need to introduce a lock. Now when the second request tries to
lock the ballot, it finds it's already locked by the first request, and
will wait for the transaction of the first request to finish before
checking whether there are sufficient funds.
Note we need to disable transactions during the test; otherwise the
second thread will wait for the first one to finish.
Also note that we need to update a couple of tests because records are
reloaded when they're locked.
In one case, reloading the ballot causes `ballot.user` to be `nil`,
since the user is hidden. So we hide the user after creating all its
associated records (which is the scenario that would take place in real
life).
In the other case, reloading the ballot causes `ballot.user` to reload
as well. So we need to reload the user object used in the test too so it
gets the updates done on `ballot.user`.
I haven't been able to reproduce this behavior in a system test. The
following test works with Rails 5.0, but it stopped working when we
moved to system tests in commit 9427f014. After that commit, for reasons
I haven't been able to debug (reintroducing truncation with
DatabaseClaner didn't seem to affect this test, and neither did
increasing the number of threads in Puma), the two AJAX requests
executed here are no longer simultaneous; the second request waits for
the first one to finish.

Recent versions introduce the `Layout/SpaceAroundMethodCallOperator`,
which we are going to use. We aren't upgrading to the latest rubocop
version because it conflicts with the version of Capybara we're using
and because it isn't supported by Hound.
Some rules have been renamed:
Layout/IndentAssignment is now Layout/AssignmentIndentation
Layout/IndentHeredoc is now Layout/HeredocIndentation
Layout/LeadingBlankLines is now Layout/LeadingEmptyLines
Layout/Tab is now Layout/IndentationStyle
Layout/TrailingBlankLines is now Layout/TrailingEmptyLines
Lint/StringConversionInInterpolation is now Lint/RedundantStringCoercion
Metrics/LineLength is now Layout/LineLength
Note after upgrading we get a new "offense" in the `StartWith` rule, so
we're changing the code in order to fix it.
Rails 5.1 updated the `method_source` dependency, which is incompatible
with pry 0.12.x (which some developers are using), and upgrading pry and
pry-byebug requires a more recent version of byebug.
Rails 5.1 introduced certain changes in the way a record is touched when
the counter cache option is enabled in a belongs to association.
We need to upgrade acts-as-taggable-on so it keeps changing the
`updated_at` attribute when a new tag is added to a record.
Note we now need to reload the records in some cases to get the
`context_tag_list` method to return what we expect. Methods like
`context_tags` however work properly with no need to reload the record.
Note we need to upgrade the bullet gem, although another option would be
to remove it completely.
Now we don't need the rubocop rules for deprecated methods, since using
them will raise an error and we'll be notified immediately.
