This is a squash of the following commits, from first to last:
-
Fix minor, random things I’ve come across lately that individually
did not seem worth making a PR for, so I saved them for one commit.
One common error is using “it’s” (which is an abbreviation of “it is”)
when the possessive “its” should be used for indicating possession.
-
Changes include the name of a test, so remove the `[skip ci]` (thanks @senny).
-
Line wrap the changes at 80 chars and add one more doc fix.
-
Add a missing line wrap in the Contributing to Ruby on Rails Guide.
-
Line wrap the `TIP` section in the Contributing to Ruby on Rails Guide as well.
Rendering the guide locally with `bundle exec rake guides:generate` did
not show any change in on-screen formatting after adding the line wrap.
The HTML generated is (extra line added to illustrate where the line
wrap takes place):
<div class="info"><p>Please squash your commits into a single commit
when appropriate. This
simplifies future cherry picks and also keeps the git log
clean.</p></div>
-
Squash commits.
This reverts commit 524d40591eaa2f4d007409bfad386f6b107492eb, reversing
changes made to 34d3a6095100245283861ef480a54d0643bbee4c.
Reasoning behind the revert are in the PR discussion:
https://github.com/rails/rails/pull/19755
- This means that types can no longer cast to/from `Set`, and reasonably
work with `where` (we already have this problem for `array`/`json`
types on pg)
- This adds precedent for every other `Enumerable`, and we can't target
`Enumerable` directly.
- Calling `to_a` on a `Set` is reasonable.
Previously `#where` used to treat `Set`objects as nil, but now it treats
them as an array:
set = Set.new([1, 2])
Author.where(:id => set)
# => SELECT "authors".* FROM "authors" WHERE "authors"."id" IN (1, 2)
We don't actually need to enumerate the possible types here any more;
that dates back to before e105e599e706780905d4c348394da989de3b200f, when
they were symbols, and indistinguishable from other options.
The implementation of the generation of the foreign key name was changed
between Rails 4.2.0 and 4.2.1 from a random to a deterministic behavior,
however the documentation still describes the old randomized behavior.
[fixes#18606]
Make belongs_to use touch over touch_later when running the callbacks.
Add more tests and small method rename
Thanks Jeremy for the feedback.
test case for use singular table name if pluralize_table_names is setted as false while creating foreign key
refactor references foreign key addition tests
use singular table name while removing foreign key
merge foreign key singular table name methods
remove unnecessary drop table from test
`sql_runtime` was getting invoked even when the logger was set to fatal.
This ensures that does not happen by checking that the logger is set to
info level before logging the view runtime.
This reduces the number of times `sql_runtime` is called for integration
tests with a fatal logger from 6 to 2.
When replacing a has_many association with the same one, there is nothing to do with database but a setter method should still return the substituted value for backward compatibility.
https://github.com/ruby/ruby/pull/579 - there is a new optimization
since ruby 2.2
Previously regexp patterns were faster (since a string was converted to
regexp underneath anyway). But now string patterns are faster and
better reflect the purpose.
Benchmark.ips do |bm|
bm.report('regexp') { 'this is ::a random string'.gsub(/::/, '/') }
bm.report('string') { 'this is ::a random string'.gsub('::', '/') }
bm.compare!
end
# string: 753724.4 i/s
# regexp: 501443.1 i/s - 1.50x slower
- Eager loading was not working for the default_scope (class method)
for 'find' & 'find_by' methods.
- Fixed these by adding a new check 'respond_to?(:default_scope)'.
We were never clearing the `PG::Result` object used to query the types
when the connection is first established. This would lead to a
potentially large amount of memory being retained for the life of the
connection.
Investigating this issue also revealed several low hanging fruit on the
performance of these methods, and the number of allocations has been
reduced by ~90%.
Fixes#19578
When set to an integer, a warning will be logged whenever a result set
larger than the specified size is returned by a query. Fixes#16463
The warning is outputed a module which is prepended in an initializer,
so there will be no performance impact if
`config.active_record.warn_on_records_fetched_greater_than` is not set.
