* 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.

* Freeze string literals when not mutated.schneems2015-07-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

* Fix regression in #20017: wrong number of arguments errorJon Atack2015-05-301-3/+3

* Reduce the number of times `#clean_path_info` is calledeileencodes2015-02-181-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | It's unnecessary to call `#clean_path_info`. It doesn't need to be called on the path with each extension. This reduces allocations to `Rack::Utils` in integration tests. Before `#clean_path_info` from `Rack::Utils` (line 622) was number 2 in top 5 allocations: ``` [["rack/lib/rack/utils.rb", 499, :T_STRING], [51034, 4539, 71559, 0, 12, 1791120]] [["rack/lib/rack/utils.rb", 662, :T_STRING], [33012, 0, 27930, 0, 1, 1226009]] [["rails/activesupport/lib/active_support/notifications/fanout.rb", 55, :T_DATA], [29998, 0, 25380, 0, 1, 3230600]] [["rails/activesupport/lib/active_support/subscriber.rb", 99, :T_STRING], [29996, 0, 25378, 0, 2, 1113840]] [["rails/activesupport/lib/active_support/notifications/instrumenter.rb", 52, :T_HASH], [29994, 147, 27014, 0, 11, 4897784]] ``` After `#clean_path_info` from `Rack::Utils` (line 622) does not appear in the top 5 highest allocations: ``` [["rack/lib/rack/utils.rb", 499, :T_STRING], [47617, 2414, 68969, 0, 12, 1667360]] [["rack/lib/rack/body_proxy.rb", 34, :T_ARRAY], [28230, 0, 26060, 0, 1, 1046800]] [["rails/activesupport/lib/active_support/notifications/fanout.rb", 55, :T_DATA], [28208, 0, 26042, 0, 1, 3034096]] [["rails/activesupport/lib/active_support/subscriber.rb", 99, :T_STRING], [28204, 0, 26040, 0, 1, 1046080]] [["rails/activesupport/lib/active_support/callbacks.rb", 165, :T_DATA], [28200, 0, 26046, 0, 2, 3451800]] ```
* FileHandler should not be called for files outside the rootAaron Patterson2014-10-101-2/+12
| | | | | FileHandler#matches? should return false for files that are outside the "root" path.
* Refactor out Dir.glob from ActionDispatch::Staticschneems2014-08-271-20/+5
| | | | | | | | Dir.glob can be a security concern. The original use was to provide logic of fallback files. Example a request to `/` should render the file from `/public/index.html`. We can replace the dir glob with the specific logic it represents. The glob {,index,index.html} will look for the current path, then in the directory of the path with index file and then in the directory of the path with index.html. This PR replaces the glob logic by manually checking each potential match. Best case scenario this results in one less file API request, worst case, this has one more file API request. Related to #16464 Update: added a test for when a file of a given name (`public/bar.html` and a directory `public/bar` both exist in the same root directory. Changed logic to accommodate this scenario.

* Enable gzip compression by defaultschneems2014-08-201-14/+40
| | | | | | If someone is using ActionDispatch::Static to serve assets and makes it past the `match?` then the file exists on disk and it will be served. This PR adds in logic that checks to see if the file being served is already compressed (via gzip) and on disk, if it is it will be served as long as the client can handle gzip encoding. If not, then a non gzip file will be served. This additional logic slows down an individual asset request but should speed up the consumer experience as compressed files are served and production applications should be delivered with a CDN. This PR allows a CDN to cache a gzip file by setting the `Vary` header appropriately. In net this should speed up a production application that are using Rails as an origin for a CDN. Non-asset request speed is not affected in this PR.

* Fix Encoding::CompatibilityError when public path is UTF-8Andrew White2013-12-291-3/+3
| | | | | | | | | | | | | | In #5337 we forced the path encoding to ASCII-8BIT to prevent static file handling from blowing up before an application has had chance to deal with possibly invalid urls. However this has a negative side effect of making it an incompatible encoding if the application's public path has UTF-8 characters in it. To work around the problem we check to see if the path has a valid encoding once it has been unescaped. If it is not valid then we can return early since it will not match any file anyway. Fixes #13518

* Invert precedence of content in ActionDispatch::StaticAndrew White2012-12-061-7/+11
| | | | | | | | | | This commit inverts the precedence in ActionDispatch::Static so that dynamic content will be served before static content. This is so that precompiled assets do not inadvertently get included when running in development mode - it should have no effect in production where static files are usually handled by the web server.

| | | | | | | | | | | RFC 3986[1] allows sub-delim characters in path segments unencoded, however Rack::File requires them to be encoded so we use URI's unescape method to leave them alone and then escape them again. Also since the path gets passed to Dir[] we need to escape any glob characters in the path. [1]: http://www.ietf.org/rfc/rfc3986.txt
