* Warn default gems which will be gemified in futureNobuyoshi Nakada2023-07-281-0/+2

* Setup SyntaxSuggest as default gemschneems2022-08-191-0/+7
| | | | | | | | | | | | | | | | | Adds the `syntax_suggest` syntax error display tool to Ruby through the same mechanism as `error_highlight` and `did_you_mean`. Reference ticket: https://bugs.ruby-lang.org/issues/18159 close #4845 ## What is syntax_suggest? When a syntax error is raised by requiring a file, dead_end will use a combination of indentation and lexing to identify the problem. > Note: Previously this tool was named `dead_end`. ## Known issues - SyntaxSearch's approach of showing syntax errors only works through integration with `require`, `load`, `autoload`, and `require_relative` (since it monkeypatches them to detect syntax errors). It does not work with direct Ruby file invocations https://github.com/zombocom/dead_end/issues/31. - This causes failure in the test suite (test_expected_backtrace_location_when_inheriting_from_basic_object_and_including_kernel) and confusion when inspecting backtraces if there's a different error when trying to require a file such as measuring memory (https://github.com/zombocom/syntax_suggest/issues/124#issuecomment-1006705016). - Discussed fix. We previously talked about opening up `SyntaxError` to be monkeypatched in the same way that other gems hook into `NoMethodError`. This is currently not possible and requires development work. When we last talked about it at RubyKaigi Nobu expressed an ability to make such a change.

* Don't fail when 'did_you_mean' is not available.Vít Ondruch2020-12-021-1/+5
| | | | | | | | | | Although 'did_you_mean' is always available in upstream Ruby, it might not be available when speed, memory, disk or network bandwidth is a concern. This is typically the case for production environment, where 'did_you_mean' is of limited usage. Also it might not be available optionally when Ruby is delivered via packaging systems. E.g. Linux distributions.
* Do not call 'gem "did_you_mean"' for nowYuki Nishijima2019-11-301-8/+2
| | | | | | | | | | | | | | This will slow down the time that the +require+ method takes to load DYM, but this has caused a build failure in a certain situation: https://ci.appveyor.com/project/ruby/ruby/builds/29214253/job/r9u9c8p95tnlftt3#L24965 which is reported as a separate bug: https://bugs.ruby-lang.org/issues/16382?next_issue_id=16381 For now this commit should fix the builds, but we should come back and add back the 'gem' call.
* Reduce system calls by activating the `did_you_mean` gem.tenderlove2016-02-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Activating the gem puts the gem on the load path, where simply requiring the file will search every gem that's installed until it can find a gem that contains the `did_you_mean` file. Calling RubyGems' `require` will search each installed gem until it can find one that contains the file it should require. This means that the more gems you have installed, the longer it can take to require that gem. To see this in action, lets compare the number of `stat` calls for a "bare require" vs the number of `stat` calls for a require that follows a gem activation by using these two programs: ``` [aaron@TC rubygems (master)]$ cat req_dym.rb begin require 'did_you_mean' rescue LoadError end [aaron@TC rubygems (master)]$ cat gem_dym.rb begin gem 'did_you_mean' require 'did_you_mean' rescue Gem::LoadError, LoadError end ``` The first program just requires the `did_you_mean` gem, where the second one activates the gem, then requires it. We can count the number of `stat` calls using `dtrace`: ``` [aaron@TC rubygems (master)]$ ruby -v ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15] [aaron@TC rubygems (master)]$ sudo dtrace -q -n 'syscall::stat*:entry { printf("%s\n", copyinstr(arg0)); }' -c`rbenv which ruby`" --disable-did_you_mean req_dym.rb" | wc -l dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 283 [aaron@TC rubygems (master)]$ sudo dtrace -q -n 'syscall::stat*:entry { printf("%s\n", copyinstr(arg0)); }' -c`rbenv which ruby`" --disable-did_you_mean gem_dym.rb" | wc -l dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 13 ``` The "bare require" version does over 10x the number of stat calls compared to the "gem, then require" version. Of course the number for the first one depends on the number of gems you have installed that sort before the `did_you_mean` gem. Lets also look at trunk Ruby: ``` [aaron@TC rubygems (master)]$ ruby -v ruby 2.4.0dev (2016-02-25 trunk 53940) [x86_64-darwin15] [aaron@TC rubygems (master)]$ sudo dtrace -q -n 'syscall::stat*:entry { printf("%s\n", copyinstr(arg0)); }' -c`rbenv which ruby`" --disable-did_you_mean req_dym.rb" | wc -l dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 2325 [aaron@TC rubygems (master)]$ sudo dtrace -q -n 'syscall::stat*:entry { printf("%s\n", copyinstr(arg0)); }' -c`rbenv which ruby`" --disable-did_you_mean gem_dym.rb" | wc -l dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 dtrace: error on enabled probe ID 3 (ID 826: syscall::stat64:entry): invalid user access in action #1 at DIF offset 24 685 ``` This change will reduce the number of `stat` calls on trunk Ruby too, but since this installation doesn't have the `did_you_mean` gem, RubyGems is still reading every gem spec file so that it can raise a `Gem::LoadError` exception with a nice error message. If we can modify RubyGems a little, it may be possible to drop the number of stat calls even on a Ruby installation that doesn't have the `did_you_mean` gem. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@53941 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
