* Remove (another) array allocationschneems2015-07-301-5/+14
| | | | | | We don't always need an array when generating a url with the formatter. We can be lazy about allocating the `missing_keys` array. This saves us: 35,606 bytes and 889 objects per request
* Remove array allocationschneems2015-07-301-2/+2
| | | | | | THe only reason we were allocating an array is to get the "missing_keys" variable in scope of the error message generator. Guess what? Arrays kinda take up a lot of memory, so by replacing that with a nil, we save: 35,303 bytes and 886 objects per request
* Avoid hash duplication by skipping mutationschneems2015-07-301-2/+2
| | | | | | If we don't mutate the `recall` hash, then there's no reason to duplicate it. While this change doesn't get rid of that many objects, each hash object it gets rid of was massive. Saves 888 string objects per request, 206,013 bytes (thats 0.2 mb which is kinda a lot).
* Only allocate new string when neededschneems2015-07-301-1/+7
| | | | | | Instead of calling `sub` on every link_to call for controller, we can detect when the string __needs__ to be allocated and only then create a new string (without the leading slash), otherwise, use the string that is given to us. Saves 888 string objects per request, 35,524 bytes.
* Freeze a string in comparatorschneems2015-07-301-1/+1
| | | | Saves 888 string objects per request.
* Avoid calling to_s on nil in journey/formatterschneems2015-07-301-2/+2
| | | | | | | | When `defaults[key]` in `generate` in the journey formatter is called, it often returns a `nil` when we call `to_s` on a nil, it allocates an empty string. We can skip this check when the default value is nil. This change buys us 35,431 bytes of memory and 887 fewer objects per request. Thanks to @matthewd for help with the readability
* Reduce hash allocations in route_setschneems2015-07-291-1/+1
| | | | | | | | When generating a url with `url_for` the hash of arguments passed in, is dup-d and merged a TON. I wish I could clean this up better, and might be able to do it in the future. This change removes one dup, since it's literally right after we just dup-d the hash to pass into this constructor. This may be a breaking, change but the tests pass...so :shipit: we can revert if it causes problems This change buys us 205,933 bytes of memory and 887 fewer objects per request.
* Decrease route_set allocationsschneems2015-07-291-3/+7
| | | | | | | | In handle_positional_args `Array#-=` is used which allocates a new array. Instead we can iterate through and delete elements, modifying the array in place. Also `Array#take` allocates a new array. We can build the same by iterating over the other element. This change buys us 106,470 bytes of memory and 2,663 fewer objects per request.
* Speed up journey missing_keysschneems2015-07-291-3/+15
| | | | | | | | Most routes have a `route.path.requirements[key]` of `/[-_.a-zA-Z0-9]+\/[-_.a-zA-Z0-9]+/` yet every time this method is called a new regex is generated on the fly with `/\A#{DEFAULT_INPUT}\Z/`. OBJECT ALLOCATIONS BLERG! This change uses a special module that implements `===` so it can be used in a case statement to pull out the default input. When this happens, we use a pre-generated regex. This change buys us 1,643,465 bytes of memory and 7,990 fewer objects per request.
* Speed up journey extract_parameterized_partsschneems2015-07-291-2/+3
| | | | | | | | Micro optimization: `reverse.drop_while` is slower than `reverse_each.drop_while`. This doesn't save any object allocations. Second, `keys_to_keep` is typically a very small array. The operation `parameterized_parts.keys - keys_to_keep` actually allocates two arrays. It is quicker (I benchmarked) to iterate over each and check inclusion in array manually. This change buys us 1774 fewer objects per request

| * | Remove unnecessary `dup` from Mapper `add_route`Roque Pinel2015-07-011-1/+1
| | | | | | | | | | | | | | | | | | | | | The `dup` was introduced by c4106d0c08954b0761726e0015ec601b7bc7ea4b to work around a frozen key. Nowadays, the string is already being duplicated by the `tr` in `options[:action] ||= action.tr('-', '_')` and later joined into a new string in `name_for_action`.

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`.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Rack implements `redirect?` so we don't need itAaron Patterson2015-07-141-3/+0
| | | | | | | | | | | | Rack [already implements `redirect?` on the response object](https://github.com/rack/rack/blob/1569a985e17d9caaf94d0e97d95ef642c4ab14ba/lib/rack/response.rb#L141) so we don't need to implement our own.
* | | use a lookup table for `assert_response`Aaron Patterson2015-07-131-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | We shouldn't depend on specific methods imlemented in the TestResponse subclass because the response could actually be a real response object. In the future, we should either push the aliased predicate methods in TestResponse up to the real response object, or remove them
