* use a request object to access info from env in GetIpAaron Patterson2015-08-062-11/+19
| | | | | | | again, we want to hide the contents of `env` from the implementation. Allocate a request object to access the contents of env, but save allocations due to string literal allocations when accessing the env hash.
* ask the request if we should show exceptionsAaron Patterson2015-08-063-4/+13
| | | | | hide the env key in the request object so that other code doesn't need to know.
* ExceptionWrapper doesn't need to know about `env`Aaron Patterson2015-08-063-9/+7
| | | | | | ExceptionWrapper only cares about the backtrace cleaner, so lets just pass the cleaner to the wrapper. It does not need to know that env exists or what key the backtrace cleaner is stored in

* reuse the request object in the File serving middlewareAaron Patterson2015-08-061-9/+13
| | | | | | | Implement `serve` on the middleware. Nothing can be placed between the instance of FileHandler and Static because Static instantiates an instance of FileHandler. IOW there is no reason to implement the `call` API in this case.

| | | | | | | | | | `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.

* | | stop using an options hash with the cookie jarAaron Patterson2015-08-051-38/+30
| | | | | | | | | | | | | | | | | | | | | | | | The cookie jar can just ask the request object for the information it needs. This allows us to stop allocating hashes for options, and also allows us to delay calculating values in advance. Generating the options hash forced us to calculate values that we may never have needed at runtime
* | | move env access to the request object.Aaron Patterson2015-08-052-14/+46
| | | | | | | | | | | | | | | | | | Accessing a request object has nice advantages over accessing a hash. If you use a missing method name, you'll get an exception rather than a `nil` (is one nice feature)

* | 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

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

* | | 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`.
