Date: 2019-05-20T15:43:42+00:00 Subject: [ruby-core:92730] [Ruby trunk Bug#15856] Idempotent performance of Kernel.require with many activated gems is slow Issue #15856 has been updated by deivid (David Rodr�guez). I had a look at this. I manage to reproduce the issue only when requiring `openssl`. In general, I think it can be reproduced when a ruby feature requires an extension of the same name. In this case, `require "openssl"` resolves to requiring `openssl.rb`, which internally requires among other stuff `openssl.so`. To reproduce, I required openssl a lot of times, expecting that after the first time the require would have no overhead. However, ``` $ time ruby --disable-gems -e '100000.times { require "openssl" }' real 0m3,075s user 0m1,732s sys 0m1,301s ``` The problem can be workaround by explicitly specifying the extension ``` $ time ruby --disable-gems -e '100000.times { require "openssl.rb" }' 2>&1 real 0m0,137s user 0m0,113s sys 0m0,029s ``` I took a lot at fixing it and came up with this patch ```diff diff --git a/load.c b/load.c index 576464fb68..ae89f63820 100644 --- a/load.c +++ b/load.c @@ -908,6 +908,11 @@ search_required(VALUE fname, volatile VALUE *path, int safe_level, feature_func if (loading) *path = rb_filesystem_str_new_cstr(loading); return 'r'; } + else if ((ft = rb_feature_p(ftptr, 0, FALSE, FALSE, &loading)) == 's') { + if (loading) *path = rb_filesystem_str_new_cstr(loading); + return 's'; + } + tmp = fname; type = rb_find_file_ext_safe(&tmp, loadable_ext, safe_level); switch (type) { ``` However, that breaks the following spec: ```ruby it "loads a .rb extensioned file when a C-extension file of the same name is loaded" do $LOADED_FEATURES << File.expand_path("load_fixture.bundle", CODE_LOADING_DIR) $LOADED_FEATURES << File.expand_path("load_fixture.dylib", CODE_LOADING_DIR) $LOADED_FEATURES << File.expand_path("load_fixture.so", CODE_LOADING_DIR) $LOADED_FEATURES << File.expand_path("load_fixture.dll", CODE_LOADING_DIR) path = File.expand_path "load_fixture", CODE_LOADING_DIR @object.require(path).should be_true ScratchPad.recorded.should == [:loaded] end ``` I'm not sure that spec is expected behavior, though. It was introduced during [this refactoring](https://github.com/ruby/spec/commit/3f03b2989b9bc6d92c4c60989d0cafe604d20d50), but I think the refactoring changed the expectations, because the previous spec I think this spec comes from reads like this: ```ruby it "will load file.rb when given 'file' if it exists even if file. is loaded" do $LOADED_FEATURES << "require_spec_3.#{Config::CONFIG['DLEXT']}" require('require_spec_3.rb').should be_true $LOADED_FEATURES.grep(/require_spec_3\.rb/).should_not == [] end ``` and while the description is what the spec tests nowadays, the implementation explictly included an extension, while the current spec does not. Essentially I think it comes down to whether the correct behavior is the current one: ``` irb(main):001:0> require 'openssl.so' => true irb(main):002:0> require 'openssl' => true irb(main):003:0> ``` or the one after my patch: ``` irb(main):001:0> require 'openssl.so' => true irb(main):002:0> require 'openssl' => false ``` If the expected behavior is the current one, then obviously my patch doesn't work. ---------------------------------------- Bug #15856: Idempotent performance of Kernel.require with many activated gems is slow https://bugs.ruby-lang.org/issues/15856#change-78092 * Author: lamont (Lamont Granquist) * Status: Assigned * Priority: Normal * Assignee: hsbt (Hiroshi SHIBATA) * Target version: * ruby -v: ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- With many activated gems the performance of Kernel.require (aka Kernel.gem_original_require after rubygems is loaded) is very slow, even in the case where the require has already been loaded (the idempotent case). What it looks like is happening is every time it needs to resolve the string argument to a pathname in order to compare against a cache of already loaded paths. Since require and require_relative need to be able to share state this makes sense to do, but this becomes very expensive with lots of activated gems, particularly on windows (where open/stat on windows is 10x more expensive than on linux). What probably needs to happen is that for require (but not require_relative which is already fairly fast) there needs to a be another layer of idempotency checking that happens which compares only the string argument in a Hash to see if the key exists or not (which I believe is likely the old way that require used to work before require_relative was introduced). That means that on the second time a require line was processed it would find that value was true and would short circuit without doing any File I/O to resolve the filename. Of course the first time it still would need to do the check resolve to the full path and still maintain that cache so that require and require_relative were still idempotent between them. After doing some testing I don't think this would introduce any user-visible behavior changes, since requires lines should always be idempotent. I thought it would fix some actual bugs in behavior but I was unable to "trick" the existing loader into double-loading a requires line even though I tried installing and activating gems after having already required system libs. Since I couldn't find any bugs, though, that also means that this should be backwards compatible with existing behavior. An strace of the process of a single `require "openssl"`, after it has been already required looks like this: open("/opt/chef/embedded/lib/ruby/gems/2.6.0/gems/uuidtools-2.1.5/lib/openssl.rb",
