| * Remove duplicated `Array#to_param`yui-knk2015-08-011-4/+2
| | | | | | | | | | `Array#to_param` is defind in active_support/core_ext/object/to_query.rb, so we can call `to_param` if value is_a Array.
* | Use #start_with? and #[] for speedBenjamin Quorning2015-08-021-2/+2

* | 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.
* | 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.

| * 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`.
* | Freeze string literals when not mutated.schneems2015-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* | Make AC::Parameters not inherited from HashPrem Sichanugrist2015-07-151-0/+4
|/ | | | | | | | 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.
* [ci skip] Improve the url_for documentationRoque Pinel2015-07-011-3/+19
| | | | | | | | | Clarify the `url_for` usage in mailers. Re-add the documentation about `url_for` and Route's path parameters, first introduced by 5c4f1859970d06228a0b67cad6d4486c1526ef2a. This was reported on #15097 and until it is decided to deprecate it or not, I believe the documentation should exist.

| | | | | | | | | | | | | | | | | | Fixed an issue where the `RAILS_RELATIVE_URL_ROOT` environment variable is not prepended to the path when `url_for` is called. If `SCRIPT_NAME` (used by Rack) is set, it takes precedence.
* | | be optimistic about missing route keysAaron Patterson2015-03-021-13/+15
| | | | | | | | | | | | | | | | | | | | | this patch makes errors slightly more expensive when someone is missing a route key, but in exchange it drops 4 allocations per `url_for` call. Since missing a route key is an error, optimizing for the non-error path seems like a good trade off

| * | Improve shorthand matching for routesbrainopia2015-01-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shorthand route match is when controller and action are taken literally from path. E.g. get '/foo/bar' # => will use 'foo#bar' as endpoint get '/foo/bar/baz' # => will use 'foo/bar#baz' as endpoint Not any path with level two or more of nesting can be used as shortcut. If path contains any characters outside of /[\w-]/ then it can't be used as such. This commit ensures that invalid shortcuts aren't used. ':controller/:action/postfix' - is an example of invalid shortcut that was previosly matched and led to exception: "ArgumentError - ':controller/:action' is not a supported controller name"

| | | | | | | | | | | | | | | | | | | | | | | | | | | This has 2 effects: 1. RoutesProxy is CRAZY faster because it's no longer creating a new Module each time method_missing is hit. 2. It bypasses an existing bug in ruby that makes `class << obj` unsafe to be used in threading contexts.
