* pass the path ast downAaron Patterson2015-08-141-3/+2
| | | | | now we don't need to add it to a hash and delete it from the hash later just to pass it around
* stop adding path_info to the conditions hashAaron Patterson2015-08-141-1/+0
| | | | we don't need to keep adding it and deleting if from hashes.
* `build_path` doesn't need the path variable anymoreAaron Patterson2015-08-131-2/+2
| | | | | It just constructs a Path::Pattern object with the AST that it already has
* remove StrexpAaron Patterson2015-08-131-7/+1
| | | | | This was a useless object. We can just directly construct a Path::Pattern object without a Strexp object.
* pass anchor directly to `Pattern`Aaron Patterson2015-08-131-3/+2
| | | | | the caller already has it, there is no reason to pack it in to an object and just throw that object away.
* we already have access to the AST, so just use itAaron Patterson2015-08-131-3/+3

* remove default arguments that aren't usedAaron Patterson2015-08-131-1/+1
| | | | | we always pass all parameters, so there is no reason to provide default arguments.
* Remove wrong commentRafael Mendonça França2015-08-091-1/+0
| | | | | This method raises conditionally not always so we should not documment as it always raise.
* Remove the conditional since it is done in the methodRafael Mendonça França2015-08-091-4/+4
|
* Execute the block when the controller doesn't existRafael Mendonça França2015-08-091-0/+1
| | | | | We should return when the contoller key is not present or if the controller doesn't exist and we didn't raised an error.
* stop calling `scope` internallyAaron Patterson2015-08-081-6/+1
| | | | | | | we need to get a grip on what `scope` actually does. This commit removes some of the internal calls to `scope`. Eventually we should add public facing methods that provide the API that `scope` is trying to accomplish.
* remove useless conditionalAaron Patterson2015-08-081-1/+1
| | | | | | `prepare_params!` would raise an exception if `params` wasn't initialized, so it must always be available. Remove the existence conditional from the `controller` method.
* eliminate assignment in conditionalAaron Patterson2015-08-081-1/+3
| | | | | The method we called already has the conditional we need. Just add an else block so that we don't need two tests.
* Remove `defaults` hash from `Dispatcher`Aaron Patterson2015-08-081-7/+7
| | | | | | | `Dispatcher` doesn't need to hold on to the defaults hash. It only used the hash to determine whether or not it should raise an exception if there is a name error. We can pass that in further up the stack and alleviate Dispatcher from knowing about that hash.

* | 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.
* 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)

| * Fallback to RAILS_RELATIVE_URL_ROOT in `url_for`.Yasyf Mohamedali2015-02-241-1/+3
| | | | | | | | | | | | 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
* | use arg size for parallel iterationAaron Patterson2015-03-021-1/+1
| | | | | | | | | | we already know the length of the args, so we can use that length for parallel iteration and cut down on allocations for `url_for` calls.
* | ask the routes objects for its Rack env keyAaron Patterson2015-03-021-0/+2
|/ | | | | | this centralizes the logic for determining the script name key and drops object allocations when calling `engine_script_name` (which is called on each `url_for`).
* Cache url_helpers instead of creating each timeEvan Phoenix2015-02-191-1/+3
| | | | | | | | | 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.

* `RouteSet` should not be listed in the public API [ci skip]Sean Griffin2015-02-031-10/+10
| | | | | The use of `# :startdoc:` inside of the class was overriding the outer-most `# :nodoc:`, causing it to be listed in the documented API.
* Cache `url_helpers` separately for mailersAndrew White2015-02-011-44/+50

* Cache `url_helpers`eileencodes2015-02-011-42/+44
