Prevents double submission by making disable_with the default. Default disable_with option will only be applied if user has not specified her/his own disable_with option, whether that is in the `data-disable-with` string form or the `:data => { :disable_with => "Saving..." }` hash form. disable_with will default to the value attribute. A configuration option was added to opt out of this functionality if the user so desires. `config.action_view.automatically_disable_submit_tag = false`

Sometimes you need a specific break sequence while using word wrap and as today the only option we have is "\n" and is hardcoded. With this change you will be able to specify any break sequence ("\r\n" for example) as an option. adding proper documentation for break_sequence in ActionView::Helpers::TextHelper.word_wrap adding some more documentation for word_wrap custom break sequence and making sure we use new hash syntax

If, doing a test like this: ``` class BugTest < ActionView::TestCase def test_foo omg end ``` Will raise with: ``` RuntimeError: In order to use #url_for, you must include routing helpers explicitly. For instance, `include Rails.application.routes.url_helpers`. ``` Thats a bit confusing, as we are not calling url_for at all.

Browsers have not been limited to two connections per host for quite some time now. With more connections allowed, the trade-off involved in asset host distribution isn't so clear and it becomes more important that developers measure actual performance before and after.

In the `tag_options` method, strings are continuously added to the `output` string. Previously, we concatenated two strings and added the generated string to `output`. By adding each of the strings to `output`, one after the other, we will save the allocation of that concatenated string. Benchmark: require 'benchmark/ips' sep = " ".freeze Benchmark.ips do |x| x.report("string +") { output = "" output << sep + "foo" } x.report("string <<") { output = "" output << sep output << "foo" } x.compare! end Results (Ruby 2.2.2): Calculating ------------------------------------- string + 88.086k i/100ms string << 94.287k i/100ms ------------------------------------------------- string + 2.407M (± 5.8%) i/s - 12.068M string << 2.591M (± 7.0%) i/s - 12.917M Comparison: string <<: 2591482.4 i/s string +: 2406883.7 i/s - 1.08x slower

In the `tag_options` method an array is used to build up elements, then `Array#*` (which is an alias for `Array#join` is called to turn the array into a string. Instead of allocating an array to build a string, we can build the string we want from the beginning. Saved: 121,743 bytes 893 objects

content_tag's first argument is will generate a string with an html tag so `:a` will generate: `<a></a>`. When this happens, the symbol is implicitly `to_s`-d so a new string is allocated. We can get around that by using a frozen string instead which This change buys us 74,236 bytes of memory and 1,855 fewer objects per request.

The instrument method creates new strings, the most common action to instrument is "!render_template` so we can detect when that action is occurring and use a frozen string instead. This change buys us 113,714 bytes of memory and 1,790 fewer objects per request.

No idea why on earth this hash key isn't already optimized by MRI, but it isn't.

When an unknonwn key is passed to the hash in `PRE_CONTENT_STRINGS` it returns nil, when you call "#{nil}" it allocates a new empty string. We can get around this allocation by using a default value `Hash.new { "".freeze }`. We can avoid the `to_sym` call by pre-populating the hash with a symbol key in addition to a string key. We can freeze some strings when using Array#* to reduce allocations. Array#join can take frozen strings. This change buys us 86,600 bytes of memory and 1,857 fewer objects per request.

I wrote a utility that helps find areas where you could optimize your program using a frozen string instead of a string literal, it's called [let_it_go](https://github.com/schneems/let_it_go). After going through the output and adding `.freeze` I was able to eliminate the creation of 1,114 string objects on EVERY request to [codetriage](codetriage.com). How does this impact execution? To look at memory: ```ruby require 'get_process_mem' mem = GetProcessMem.new GC.start GC.disable 1_114.times { " " } before = mem.mb after = mem.mb GC.enable puts "Diff: #{after - before} mb" ``` Creating 1,114 string objects results in `Diff: 0.03125 mb` of RAM allocated on every request. Or 1mb every 32 requests. To look at raw speed: ```ruby require 'benchmark/ips' number_of_objects_reduced = 1_114 Benchmark.ips do |x| x.report("freeze") { number_of_objects_reduced.times { " ".freeze } } x.report("no-freeze") { number_of_objects_reduced.times { " " } } end ``` We get the results ``` Calculating ------------------------------------- freeze 1.428k i/100ms no-freeze 609.000 i/100ms ------------------------------------------------- freeze 14.363k (± 8.5%) i/s - 71.400k no-freeze 6.084k (± 8.1%) i/s - 30.450k ``` Now we can do some maths: ```ruby ips = 6_226k # iterations / 1 second call_time_before = 1.0 / ips # seconds per iteration ips = 15_254 # iterations / 1 second call_time_after = 1.0 / ips # seconds per iteration diff = call_time_before - call_time_after number_of_objects_reduced * diff * 100 # => 0.4530373333993266 miliseconds saved per request ``` So we're shaving off 1 second of execution time for every 220 requests. Is this going to be an insane speed boost to any Rails app: nope. Should we merge it: yep. p.s. If you know of a method call that doesn't modify a string input such as [String#gsub](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37) please [give me a pull request to the appropriate file](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37), or open an issue in LetItGo so we can track and freeze more strings. Keep those strings Frozen ![](https://www.dropbox.com/s/z4dj9fdsv213r4v/let-it-go.gif?dl=1)

Avoid computing the same fragment digest many times when looping over templates. The cache is cleared on every request so template changes are still picked up.

This will silence deprecation warnings. Most of the test can be changed from `render :text` to render `:plain` or `render :body` right away. However, there are some tests that needed to be fixed by hand as they actually assert the default Content-Type returned from `render :body`.

This is another take at #14384 as we decided to wait until `master` is targeting Rails 5.0. This commit is implementation-complete, as it guarantees that all the public methods on the hash-inherited Parameters are still working (based on test case). We can decide to follow-up later if we want to remove some methods out from Parameters.

If a template includes `# Template Collection: ...` anywhere in its source, that name will be used as the cache name for the partial that is rendered for the collection. This allows users to enable collection caching even if the template doesn't start with `<% cache ... do %>`. Moreover, the `# Template Collection: ...` notation is recognized in all template types (and template types other than ERB can define a resource_cache_call_pattern method to allow the `cache ... do` pattern to be recognized too).

Adds the `virtual_path` option to `cache_fragment_name` so it can be provided when needed. That allows `cache_collection_render` to get the appropriate cache key with the digest generated based on the template and prevent collision with other templates that cache the same collection.

The regular expression which was used to detect partial templates that begin with a `<% cache ... do %>` call missed some cases. This commits attempts to improve the detection for some cases such as multi-line comments at the beginning of the template. The different templates are listed in two new unit test methods. Note that specially crafted Ruby code can still evade such `cache`-call detection: for example, a user might have its own method which itself calls the Rails `cache` helper. In such a case, the template's code doesn't start with a literal `cache` string and therefore will not be eligible for collection caching.
