* | | Do not cache ActiveSupport::TimeZone#utc_offsetAlexey Shein2016-04-251-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This can be an issue when TZInfo::TimeZone#current_period is refreshed due to timezone period transition, but it's not reflected in ActiveSupport::TimeZone object. For example, on Sun, 26 Oct 2014 22:00 UTC, Moscow changed its TZ from MSK +04:00 to MSK +03:00 (-1 hour). If ActiveSupport::TimeZone['Moscow'] happens to be initialized just before the timezone transition, it will cache its stale utc_offset even after the timezone transition. This commit removes cache and fixes this issue. Signed-off-by: Jeremy Daer <jeremydaer@gmail.com>

* | Make getlocal and getutc always return instances of TimeAndrew White2016-04-232-22/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 White2016-04-237-7/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | Update delegate to use newer Ruby syntaxTodd Lynam2016-04-201-5/+2
|/ / | | | | This commit updates `delegate` to use the keyword argument syntax added in Ruby 2. I left the `ArgumentError` when `to` is missing, because it better explains how to correctly use `delegate`. We could instead rely on the default `ArgumentError` that would be raised if `to` were a required keyword argument.
* | Speed up String#blank? Regexschneems2016-04-201-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow up on https://github.com/rails/rails/commit/697384df36a939e565b7c08725017d49dc83fe40#commitcomment-17184696. 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
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See the rationale in the comment in this patch. To benchmark this I ran a number of variations, ultimately narrowing to require 'benchmark/ips' str = '' regexp = /\A[[:space:]]*\z/ Benchmark.ips do |x| x.report('regexp') { regexp === str } x.report('empty') { str.empty? || regexp === str } x.compare! end This benchmark has consistently reported speedups around 3.5x: Calculating ------------------------------------- regexp 69.197k i/100ms empty 115.468k i/100ms ------------------------------------------------- regexp 2. 6.3%) i/s - 13.839M empty 9. 8.8%) i/s - 47.804M Comparison: empty: 9642607.6 i/s regexp: 2768351.9 i/s - 3.48x slower Sometimes even reaching 4x. 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.

* | | Ruby 2.4: compat with new Array#sumJeremy Daer2016-04-181-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ruby 2.4 introduces `Array#sum`, but it only supports numeric elements, breaking our `Enumerable#sum` which supports arbitrary `Object#+`. 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`.
