* Cut string allocations in content_tag_stringschneems2015-07-296-20/+20
| | | | | | 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.
* Optimize hash keyschneems2015-07-291-1/+1
| | | | | | No idea why on earth this hash key isn't already optimized by MRI, but it isn't. :shit: This change buys us 74,077 bytes of memory and 1,852 fewer objects per request.
* Decrease string allocation in content_tag_stringschneems2015-07-291-6/+7
| | | | | | | | | | 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.

* | Freeze string literals when not mutated.schneems2015-07-192-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* | 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`.

* | Support explicit defintion of resouce name for collection caching.Dov Murik2015-07-071-0/+15
|/ | | | | | | | | | | | | | 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).

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 documentation previously stated that calling `translate(".foo")` was equivalent to calling `I18n.translate("people.index.foo")` which is incorrect due to the various other functions of the `translate` view helper. This has been fixed. Additionally, a note about forcing the view helper to re-raise exceptions was added to the section detailing the handling of missing translations. Other cleanup includes: * Consistent formatting of code * Stop indenting bulleted list as a code sample * Tighten some of the language * Wrap at 80 characters.
