| | | | | | | | | | | | Due to e25fdad2f147e6f368958f9a06a5ac9d10288408, we are correctly using path escaping for email addresses. This commit fixes the tests to expect path escaping.

| * Make disable_with default in submit_tagJustin Schiff2015-08-111-9/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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`

* Save a string allocation inside loopBenjamin Quorning2015-08-021-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Don't allocate array when not necessaryschneems2015-07-301-5/+6
| | | | | | 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
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
