* Don't blank pad day of the month when formatting datesSean Griffin2016-06-021-3/+3
| | | | | | | | | | | We are currently using `%e` which adds a space before the result if the digit is a single number. This leads to strings like `February 2, 2016` which is undesireable. I've opted to replace with 0 padding instead of removing the padding entirely, to preserve compatibility for those relying on the fact that the width is constant, and to be consistent with time formatting. Fixes #25251.

| | | | | | | | | | | | | | This reverts commit 28492204ee59a5aca2f3bc7b161d45724552686d. Reason: `suppress` without an argument doesn't actually tell what is supressing. Also, it can be confused with ActiveRecord::Base#suppress.

* | | Make getlocal and getutc always return instances of TimeAndrew White2016-04-231-14/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously these methods could return either a DateTime or a Time depending on how the ActiveSupport::TimeWithZone instance had been constructed. Changing to always return an instance of Time eliminates a possible stack level too deep error in to_time where it was wrapping a DateTime instance. As a consequence of this the internal time value is now always an instance of Time in the UTC timezone, whether that's as the UTC time directly or a representation of the local time in the timezone. There should be no consequences of this internal change and if there are it's a bug due to leaky abstractions.

* | | Move `DateTime#getlocal` to `/core_ext/date_time/calculations.rb`yui-knk2016-04-232-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | `DateTime#getlocal` is newly added public API. It's responsible is same as `DateTime#utc`, so `calculations.rb` is a best plase to define this method. For keeping consistency with `DateTime#utc`, defines `#localtime` and defines `getlocal` as an alias method.
* | | Add compatibility for Ruby 2.4 `to_time` changesAndrew White2016-04-236-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Ruby 2.4 the `to_time` method for both `DateTime` and `Time` will preserve the timezone of the receiver when converting to an instance of `Time`. Since Rails 5.0 will support Ruby 2.2, 2.3 and later we need to introduce a compatibility layer so that apps that upgrade do not break. New apps will have a config initializer file that defaults to match the new Ruby 2.4 behavior going forward. For information about the changes to Ruby see: https://bugs.ruby-lang.org/issues/12189 https://bugs.ruby-lang.org/issues/12271 Fixes #24617.
* | | just say nothing about why this regexp is slower [ci skip]Xavier Noria2016-04-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Further investigation seems to disprove that backtracking is the reason why the positive variant is slower, see https://github.com/rails/rails/pull/24658#issuecomment-213079710 so, just say nothing about it, only assert it is slower.
* | | restores code comments in String#blank? [ci skip]Xavier Noria2016-04-211-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you come here without context, it is important to hightlight that checking the predicate is worthwhile due to the observation that blank strings are often empty. So you complicate the code (which has a cost in terms of readability and aesthetics), but statistically makes sense. Then, you also need to explain why the second operand is so convoluted. Otherwise, you wonder why this line is written precisely this way. That is what code comments are for.

|/ / / | | | | | | This commit updates `delegate` to use the keyword argument syntax added in Ruby 2.

We could instead rely on the default `ArgumentError` that would be raised if `to` were a required keyword argument.

The regex to detect a blank string `/\A[[:space:]]*\z/` will loop through every character in the string to ensure that all of them are a `:space:` type. We can invert this logic and instead look for any non-`:space:` characters. When that happens, we would return on the first character found and the regex engine does not need to keep looking. Thanks @nellshamrell for the regex talk at LSRC. By defining a "blank" string as any string that does not have a non-whitespace character (yes, double negative) we can get a substantial speed bump. Also an inline regex is (barely) faster than a regex in a constant, since it skips the constant lookup. A regex literal is frozen by default. ```ruby require 'benchmark/ips' def string_generate str = " abcdefghijklmnopqrstuvwxyz\t".freeze str[rand(0..(str.length - 1))] * rand(0..23) end strings = 100.times.map { string_generate } ALL_WHITESPACE_STAR = /\A[[:space:]]*\z/ Benchmark.ips do |x| x.report('current regex ') { strings.each {|str| str.empty? || ALL_WHITESPACE_STAR === str } } x.report('+ instead of * ') { strings.each {|str| str.empty? || /\A[[:space:]]+\z/ === str } } x.report('not a non-whitespace char') { strings.each {|str| str.empty? || !(/[[:^space:]]/ === str) } } x.compare! end # Warming up -------------------------------------- # current regex # 1.744k i/100ms # not a non-whitespace char # 2.264k i/100ms # Calculating ------------------------------------- # current regex # 18.078k (± 8.9%) i/s - 90.688k # not a non-whitespace char # 23.580k (± 7.1%) i/s - 117.728k # Comparison: # not a non-whitespace char: 23580.3 i/s # current regex : 18078.2 i/s - 1.30x slower ``` This makes the method roughly 30% faster `(23.580 - 18.078)/18.078 * 100`. cc/ @fxn
* | | ~3.5x speedup of String#blank? for empty stringsXavier Noria2016-04-201-1/+6

Running the same bechmark on strings of 10 or 100 characters (with whitespace or present) has shown a slowdown of just about 1.01/1.02. Marginal, we seem to have a worthwhile trade-off here.

To fix, override `Array#sum` with our compatible implementation. Native Ruby 2.4: %w[ a b ].sum # => TypeError: String can't be coerced into Fixnum With `Enumerable#sum` shim: %w[ a b ].sum # => 'ab' We tried shimming the fast path and falling back to the compatible path if it fails, but that ends up slower even in simple causes due to the cost of exception handling. Our only choice is to override the native `Array#sum` with our `Enumerable#sum`.
