* Remove duplicates after autoloading modulesRobert Mosolgo2018-01-261-0/+1

* Enable autocorrect for `Lint/EndAlignment` copKoichi ITO2018-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Summary This PR changes .rubocop.yml. Regarding the code using `if ... else ... end`, I think the coding style that Rails expects is as follows. ```ruby var = if cond a else b end ``` However, the current .rubocop.yml setting does not offense for the following code. ```ruby var = if cond a else b end ``` I think that the above code expects offense to be warned. Moreover, the layout by autocorrect is unnatural. ```ruby var = if cond a else b end ``` This PR adds a setting to .rubocop.yml to make an offense warning and autocorrect as expected by the coding style. And this change also fixes `case ... when ... end` together. Also this PR itself is an example that arranges the layout using `rubocop -a`. ### Other Information Autocorrect of `Lint/EndAlignment` cop is `false` by default. https://github.com/bbatsov/rubocop/blob/v0.51.0/config/default.yml#L1443 This PR changes this value to `true`. Also this PR has changed it together as it is necessary to enable `Layout/ElseAlignment` cop to make this behavior.

* code gardening: removes redundant selfsXavier Noria2016-08-081-1/+1
| | | | | | | | | A few have been left for aesthetic reasons, but have made a pass and removed most of them. Note that if the method `foo` returns an array, `foo << 1` is a regular push, nothing to do with assignments, so no self required.

* Add comments to ActiveSupport::Dependencies to help understandingAaron Ang2016-03-161-0/+2
| | | | | | | | In a previous patch, all log-related stuff was removed. However, some logs are still useful to understand the code. Therefore, in this patch, I put those log messages back as comments. [ci skip]
* no need to clear an unusued collectionXavier Noria2016-03-161-1/+1
| | | | | | | | | | If the code reaches that line new_constants is no longer needed. We only need here to iterate over it to discard stuff and done. Note that constant_watch_stack.new_constants returns a new reference each time it is invoked, so that #clear call was not cleaning state in some internal structure (which would have been a bit dirty as well at this level of coupling).
* removes unreachable codeXavier Noria2016-03-161-2/+0
| | | | | | | | | | | | This array literal cannot be reached. The previous begin either returns to the caller via the explicit return in the ensure block if all goes well, or else propagates whatever make the begin block abort execution. I have investigated the origin of this a bit. In the past the ensure block didn't have a return call, see for example c08547d. Later on the return was added in 4da4506, but the trailing literal was left there.
* Remove log-related stuff from ActiveSupport::DependenciesAaron Ang2016-03-151-44/+0
| | | | | In this patch, all log-related stuff in `ActiveSupport::Dependencies` is removed because the logging is no longer useful.
* Deprecate `Module.local_constants`yui-knk2016-03-011-2/+2
| | | | | After Ruby 1.9, we can easily get the constants that have been defined locally by `Module.constants(false)`.
* Dependencies clean upSruli Rapps2016-02-191-3/+3
| | | | | | | | | | | | | | | | | | | | Cleans up four items I came across in ActiveSupport::Dependencies: - DependenciesTest# test_dependency_which_raises_exception_isnt_added_to_loaded_set: Fixes current implementation which will pass no matter what since the filepath is never added to "loaded" or "history" without being expanded first. - Remove DependenciesTest#test_unhook. Seems leftover from when alias_method_chain was used in Loadable and ModuleConstMissing. The test will always pass since Module never responds to those methods - WatchStack#new_constants documentation: update self to @stack. Looks like self was leftover from when WatchStack inherited from Hash - Remove ActiveSupport namespace from call to Dependencies.constant_watch_stack.watching? since the namespace is not needed, Dependencies is called two other times in the same method without it (even on the same line) and it brings the line to within 80 characters

* Merge pull request #20928 from matthewd/unload-interlockMatthew Draper2015-07-241-1/+8
|\ | | | | We need stricter locking before we can unload
| * We need stricter locking before we can unloadMatthew Draper2015-07-201-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | Specifically, the "loose upgrades" behaviour that allows us to obtain an exclusive right to load things while other requests are in progress (but waiting on the exclusive lock for themselves) prevents us from treating load & unload interchangeably: new things appearing is fine, but they do *not* expect previously-present constants to vanish. We can still use loose upgrades for unloading -- once someone has decided to unload, they don't really care if someone else gets there first -- it just needs to be tracked separately.
* | Don't apply locking around basic #load / #requireMatthew Draper2015-07-231-6/+4
|/ | | | | | That's outside our remit, and dangerous... if a caller has their own locking to protect against the natural race danger, we'll deadlock against it.
* 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)

* better error message for constants autoloaded from anonymous modules [fixes ↵Xavier Noria2013-12-061-7/+13
| | | | | | | | | | | | | | | | #13204] load_missing_constant is a private method that basically plays the role of const_missing. This method has an error condition that is surprising: it raises if the class or module already has the missing constant. How is it possible that if the class of module has the constant Ruby has called const_missing in the first place? The answer is that the from_mod argument is self except for anonymous modules, because const_missing passes down Object in such case (see the comment in the source code of the patch for the rationale). But then, it is better to pass down Object *if Object is also missing the constant* and otherwise err with an informative message right away.
