| * | Make digest cache work in development.Kasper Timm Hansen2015-07-182-4/+16
| | | | | | | | | | | | | | | | | | 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.

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)
* | | Stop using deprecated `render :text` in testPrem Sichanugrist2015-07-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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`.

* | Make AC::Parameters not inherited from HashPrem Sichanugrist2015-07-151-0/+10
| | | | | | | | | | | | | | | | 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.
* | Change AC::TestResponse to AD::TestResponsePrem Sichanugrist2015-07-141-1/+1
|/ | | | | ActionController::TestResponse was removed in d9fe10c and caused a test failure on Action View as its test case still refers to it.

* | Support explicit defintion of resouce name for collection caching.Dov Murik2015-07-073-6/+37
|/ | | | | | | | | | | | | | 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.

| * | Improve detection of partial templates eligible for collection caching.Dov Murik2015-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Previously, passing a falsey value to `include_blank` would be ignored if the field was required, and a blank line would still be inserted. The following will now raise instead of quietly failing: `select("post", "category", %w(a required field), { include_blank: false }, required: 'required')`

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit a9d58c77da800bb0052c9bfa432828b02526022c, reversing changes made to 041c2c879a3c4086ad3aa6d30fed1eede1d53c11. Reason: The old behavior is how it was working in previous version of Rails since 4.0.x so it is not safe to backport to a stable branch.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | When one rendered a partial template without specifying an object or a collection (e.g. <%= render partial: 'partial_name' %>), Rails would make an object called :partial_name available in local_assigns. I don't think this was the intended behavior, since no local variable called 'partial_name' gets defined in the view.
