* push `action` option extraction up one frame.Aaron Patterson2015-08-111-3/+5
|
* pull up the "options.delete(:controller)" logicAaron Patterson2015-08-111-12/+14
| | | | | | we want to try to pull this logic up to where the user actually passed in "controller" so that it's close to the related call. That way when we're down the stack, we don't need to wonder "why are we doing this?"

* Only use path if the key is not presentRafael Mendonça França2015-08-101-1/+1
| | | | | There are some cases where :path is nil on option and we should respect that.
* try to pass fewer options to `scope`Aaron Patterson2015-08-101-2/+3
| | | | We already know how to handle `path`, so lets just handle it on our own.
* always cast `name` to a symbol, and never to_s itAaron Patterson2015-08-101-2/+1
| | | | | | | All callers of `action_path` interpolate the return value in to a string, so there is no need for the method to to_s it. to_sym on a symbol will return the same symbol, though I think `action_path` may always be called with a symbol so this might not be necessary.
* pull path conditional upAaron Patterson2015-08-101-4/+6
| | | | we only need to check for `path` once.
* pull `defaults` extraction up the stack.Aaron Patterson2015-08-101-2/+6
| | | | Now we can see where `defaults` options originate
* avoid calling `scope` on `defaults` methodsAaron Patterson2015-08-101-3/+6
|
* let the `controller` method push / pop the stackAaron Patterson2015-08-101-11/+5
| | | | | since `controller` and `controller_scope` were the same, just combine them
* remove another call to `scope`Aaron Patterson2015-08-101-3/+4
|
* remove dead codeAaron Patterson2015-08-101-12/+0
| | | | | This method isn't used internally, isn't tested, isn't documented. We should delete it.
* avoid is_a? callsAaron Patterson2015-08-101-1/+5
| | | | | add a predicate method so that we can avoid is_a? calls on the resource object.
* avoid another call to `scope`Aaron Patterson2015-08-101-1/+1
| | | | | calling `scope` isn't cheap, so try to call cheaper methods that do the same thing for those particular parameters (in this case `path_scope`)
* push `with_scope_level` up so resource_scope doesn't knowAaron Patterson2015-08-101-25/+27
| | | | | `resource_scope` should just put resource scopes on the stack, and doesn't need to know what a `scope_level` is.
* reuse the same frame so we don't need a singleton hashAaron Patterson2015-08-101-2/+1
| | | | | We just want to augment the scope level, not the frame itself, so just copy the frame to the new scope object.
* add a null node at the top of the stackAaron Patterson2015-08-101-13/+9
| | | | this gives us an easier way to iterate the stack
* remove `@nesting` ivarAaron Patterson2015-08-101-9/+21
| | | | | The same information is stored in the `@scope` linked list, so just get it from there.
* pass `shallow` in to the resource constructorAaron Patterson2015-08-101-10/+5
| | | | this lets us remove the setter and make the Resource object Read-Only
* we have the resource on the stack, so just use itAaron Patterson2015-08-101-1/+1
| | | | | We don't need to ask `scope` for the resource because we already have it right here.
* 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.
* Name the argument according with its jobRafael Mendonça França2015-08-091-2/+2

* push `scope` calls up one frameAaron Patterson2015-08-091-5/+13
| | | | | | eliminates calling `scope` in one method, pushes the other calls up one frame. This goes a little way towards eliminating the internal calls to `scope`.
* remove useless hashAaron Patterson2015-08-081-2/+2
| | | | we don't really need this hash.
* stop calling `scope` internallyAaron Patterson2015-08-082-13/+24
| | | | | | | 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 Patterson2015-08-082-9/+9
| | | | | | | `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.
* eliminate runtime conditionalAaron Patterson2015-08-081-10/+9
| | | | | | We know in advance whether the object is a dispatcher or not, so we can configure the Constraints object with a strategy that will call the right method.

* | 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.

* | 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.

| | | | | | | | | | | | | | 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.
