[ruby-core:113230] [Ruby master Bug#18947] Unexpected Errno::ENAMETOOLONG on Windows
by inversion (Yura Babak) 13 Apr '23

13 Apr '23

Issue #18947 has been updated by inversion (Yura Babak). Today rechecked that for the latest **ruby 3.2.2** (2023-03-30 revision e51014f9c0) [x64-mingw-ucrt] still we have same problems ( ---------------------------------------- Bug #18947: Unexpected Errno::ENAMETOOLONG on Windows https://bugs.ruby-lang.org/issues/18947#change-102777 * Author: inversion (Yura Babak) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- On Windows 10, I am working on a script to copy a complex folder structure. Pathname and FileUtils work fine for me until there is a folder with a **very long path** (>260 chars). Normally you cannot access such a folder with Ruby. The next operations will raise `Errno::ENOENT` ``` ruby Pathname.new(300_chars_path).children FileUtils.mkpath(300_chars_path) ``` But there is a way in Windows to remove the MAX_PATH limitation. You can find a small .reg file in this article: https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-lim… After changing this system option, things start to work strangely in Ruby. This will now raise `Errno::ENAMETOOLONG`: ``` ruby Pathname.new(300_chars_path).children ``` But at the same time, you can create a folder with such a long path and write-read a file in it ``` ruby FileUtils.mkpath(300_chars_path) file = Pathname.new(300_chars_path+'/file.txt') file.write 'oooooooooo' puts Pathname.new(300_chars_path+'/file.txt').read ``` So you can work with individual items but attempts to list such folders' content fail (`.children`, `.glob`, `.copy`, etc). In my case, deep `.glob` is broken for all the parent folders of that deep long-path folder (( The only way I found for listing is ``` ruby require 'win32ole' fso = WIN32OLE.new 'Scripting.FileSystemObject' for file in fso.GetFolder(300_chars_path).files file.name file.path.length end ``` But using this workaround breaks all my code workflow built on top of Pathname and FileUtils ((. So for me, it looks like some operations with long-path folders are not working just because in Ruby there is a check for the path length and not a real operation problem. And in some places (see .mkpath) there is no such check and all works fine. Also notice that other applications on Windows have no problems with long-path folders (like Total Commander). Please consider reviewing if we really need to raise `Errno::ENAMETOOLONG` if the `LongPathsEnabled` option is enabled in the Windows registry. -- https://bugs.ruby-lang.org/

[ruby-core:113209] [Ruby master Bug#19596] Decreased performance after upgrading from ruby 2.7.2 to ruby 3.2.2

Issue #19596 has been reported by silva96 (Benjamín Silva). ---------------------------------------- Bug #19596: Decreased performance after upgrading from ruby 2.7.2 to ruby 3.2.2 https://bugs.ruby-lang.org/issues/19596 * Author: silva96 (Benjamín Silva) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) +YJIT [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I just upgraded to ruby 3.2.2 from 2.7.2 in one Rails app in production. Tried with and without YJIT, but no matter what, I'm having worst performance. Time spent in ruby went from 20ms to more than 50ms and very inconsistent (peaks) - I'm using RVM - I've set MALLOC_ARENAS_MAX=2 I may be wrong, but I suspect I have worst performance because I see this chart in newrelic increased right after the upgrade ![](clipboard-202304130005-opyyk.png) In the picture, the chart has the "ruby" toggle, to see how much time is spent in ruby operations. But I don't see a noticeable impact on the overall response times. So that makes me think that maybe, ruby 3.2 reports differently than 2.7 in newrelic ![](clipboard-202304130014-vnb0h.png) Right now, I'm using YJIT, and I was expecting to see some kind of improvements in app performance upgrading from 2.7 to 3.2 YJIT, but there's no performance gain, is that even possible? The website is https://profe.social, it's a very standard content site, no super expensive ruby computations, most operations are rendering erb views pulling data from the database. Any Ideas how can I get performance improvements? Best regards. ---Files-------------------------------- clipboard-202304130005-opyyk.png (120 KB) clipboard-202304130014-vnb0h.png (134 KB) -- https://bugs.ruby-lang.org/

[ruby-core:112933] [Ruby master Feature#19538] Performance warnings

Issue #19538 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #19538: Performance warnings https://bugs.ruby-lang.org/issues/19538 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- Suggested by @Eregon. There are program behaviors that are supported, but that we know aren't good for performance, however it's hard for users to know about them. Now that we have warning categories, we could add a `:performance` category to allow the VM to emit warning in some situations. The category would be disabled by default, and users interested in optimizing their program could turn it on in development. ```ruby Warning[:performance] = true ``` -- https://bugs.ruby-lang.org/

[ruby-core:113213] [Ruby master Feature#18885] End of boot advisory API for RubyVM
by ioquatix (Samuel Williams) 13 Apr '23

Issue #18885 has been updated by ioquatix (Samuel Williams). Looking forward to using this. ---------------------------------------- Feature #18885: End of boot advisory API for RubyVM https://bugs.ruby-lang.org/issues/18885#change-102756 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- ### Context Many optimizations in the Ruby VM rely on lazily computed caches: Strings coderange, constant caches, method caches, etc etc. As such even without JIT, some operations need a bit of a warm up, and might be flushed if new constants are defined, new code is loaded, or some objects are mutated. Additionally these lazily computed caches can cause increased memory usage for applications relying on Copy-on-Write memory. Whenever one of these caches is updated post fork, the entire memory page is invalidated. Precomputing these caches at the end of boot, even if based on heuristic, could improve Copy-on-Write performance. The classic example is the objects generation, young objects must be promoted to the old generation before forking, otherwise they'll get invalidated on the next GC run. That's what https://github.com/ko1/nakayoshi_fork addresses. But there are other sources of CoW invalidation that could be addressed by MRI if it had a clear notification when it needs to be done. ### Proposal If applications had an API to notify the virtual machine that they're done loading code and are about to start processing user input, it would give the VM a good point in time to perform optimizations on the existing code and objects. e.g. could be something like `RubyVM.prepare`, or `RubyVM.ready`. It's somewhat similar to [Matz's static barrier idea from RubyConf 2020](https://youtu.be/JojpqfaPhjI?t=1908), except that it wouldn't disable any feature. ### Potential optimizations `nakayoshi_fork` already does the following: - Do a major GC run to get rid of as many dangling objects as possible. - Promote all surviving objects to the highest generation - Compact the heap. But it would be much simpler to do this from inside the VM rather than do cryptic things such as `4.times { GC.start }` from the Ruby side. It's also not good to do this on every fork, once you fork the first long lived child, you shouldn't run it again. So decorating `fork` is not a good hook point. Also after discussing with @jhawthorn, @tenderlovemaking and @alanwu, we believe this would open the door to several other CoW optimizations: #### Precompute inline caches Even though we don't have hard data to prove it, we are convinced that a big source of CoW invalidation are inline caches. Most ISeq are never invoked during initialization, so child processed are forked with mostly cold caches. As a result the first time a method is executed in the child, many memory pages holding ISeq are invalidated as caches get updated. We think MRI could try to precompute these caches before forking children. Constant cache particularly should be resolvable statically see https://github.com/ruby/ruby/pull/6187. Method caches are harder to resolve statically, but we can probably apply some heuristics to at least reduce the cache misses. #### Copy on Write aware GC We could also keep some metadata about which memory pages are shared, or even introduce a "permanent" generation. [The Instagram engineering team introduced something like that in Python](https://instagram-engineering.com/copy-on-write-friendly-python-gar… ([ticket](https://bugs.python.org/issue31558), [PR](https://github.com/python/cpython/pull/3705)) That makes the GC aware of which objects live on a shared page. With this information the GC can decide to no free dangling objects leaving on these pages, not to compact these pages, etc. #### Scan the coderange of all strings Strings have a lazily computed `coderange` attribute in their flags. So if a string is allocated at boot, but only used after fork, on first use its coderange will mayneed to be computed and the string mutated. Using https://github.com/ruby/ruby/pull/6076, I noticed that 58% of the strings retained at the end of the boot sequence had an `UNKNOWN` coderange. So eagerly scanning the coderange of all strings could also improve Copy on Write performance. #### malloc_trim This hook will also be a good point to release unused pages to the system with `malloc_trim`. -- https://bugs.ruby-lang.org/

[ruby-core:112818] [Ruby master Misc#19525] DevMeeting-2023-04-13
by mame (Yusuke Endoh) 13 Apr '23

13 Apr '23

Issue #19525 has been reported by mame (Yusuke Endoh). ---------------------------------------- Misc #19525: DevMeeting-2023-04-13 https://bugs.ruby-lang.org/issues/19525 * Author: mame (Yusuke Endoh) * Status: Open * Priority: Normal ---------------------------------------- # The next dev meeting **Date: 2023/04/13 13:00-17:00** (JST) Log: *TBD* - Dev meeting *IS NOT* a decision-making place. All decisions should be done at the bug tracker. - Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly. - Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue). - We will write a record of the discussion in the file or to each ticket in English. - All activities are best-effort (keep in mind that most of us are volunteer developers). - The date, time and place of the meeting are scheduled according to when/where we can reserve Matz's time. - *DO NOT* discuss then on this ticket, please. # Call for agenda items If you have a ticket that you want matz and committers to discuss, please post it into this ticket in the following format: ``` * [Ticket ref] Ticket title (your name) * Comment (A summary of the ticket, why you put this ticket here, what point should be discussed, etc.) ``` Example: ``` * [Feature #14609] `Kernel#p` without args shows the receiver (ko1) * I feel this feature is very useful and some people say :+1: so let discuss this feature. ``` - It is recommended to add a comment by 2023/04/10. We hold a preparatory meeting to create an agenda a few days before the dev-meeting. - The format is strict. We'll use [this script to automatically create an markdown-style agenda](https://gist.github.com/mame/b0390509ce1491b43610b9ebb665eb86). We may ignore a comment that does not follow the format. - Your comment is mandatory. We cannot read all discussion of the ticket in a limited time. We appreciate it if you could write a short summary and update from a previous discussion. -- https://bugs.ruby-lang.org/

[ruby-core:113097] [Ruby master Feature#19573] Add Class#singleton_inherited
by jeremyevans0 (Jeremy Evans) 12 Apr '23

12 Apr '23

Issue #19573 has been reported by jeremyevans0 (Jeremy Evans). ---------------------------------------- Feature #19573: Add Class#singleton_inherited https://bugs.ruby-lang.org/issues/19573 * Author: jeremyevans0 (Jeremy Evans) * Status: Open * Priority: Normal ---------------------------------------- This would be similar to `Class#inherited`, but would be called with singleton classes of instances instead of subclasses. This could be used to warn or raise on singleton class creation, or modify the instance to change behavior, such as allow optimizations when a singleton class does not exist, but allow fallbacks if it does exist. ```ruby c = Class.new do def self.inherited(subclass) p :inherited end def self.singleton_inherited(singleton_class) # could use singleton_class.attached_object for modifying related object p :singleton_inherited end end Class.new(c) # prints :inherited c.new.singleton_class # prints :singleton_inherited ``` This could potentially be an instance method (e.g. `Kernel#singleton_class_created` or `BasicObject#singleton_class_created`) instead of a class method. However, that would not grant any additional flexibility, since per-object behavior first requires creation of a singleton class. If this is accepted, should the method be called for singleton classes created by `Kernel#clone` if the receiver has a singleton class? I think it should, as `Class#inherited` is called for `Class#clone`. -- https://bugs.ruby-lang.org/

[ruby-core:111780] [Ruby master Bug#19331] --enable-rpath results in incorrect RPATH in Ruby 3.1.3
by Kulikjak (Jakub Kulik) 12 Apr '23

12 Apr '23

Issue #19331 has been reported by Kulikjak (Jakub Kulik). ---------------------------------------- Bug #19331: --enable-rpath results in incorrect RPATH in Ruby 3.1.3 https://bugs.ruby-lang.org/issues/19331 * Author: Kulikjak (Jakub Kulik) * Status: Open * Priority: Normal * ruby -v: 3.1.3 * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I just updated Ruby from 3.1.2 to 3.1.3 and found out that all .so libraries from the enc directory have wrong RPATH/RUNPATH (when building with `--enable-rpath`). I first hit this on Solaris, but my testing on Linux resulted in the same thing. It can be easily reproduced with the following: ``` wget http://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.3.tar.gz tar xzf ruby-3.1.3.tar.gz cd ruby-3.1.3 ./configure --prefix=/usr/ruby/3.1 --mandir=/usr/ruby/3.1/share/man --bindir=/usr/ruby/3.1/bin --sbindir=/usr/ruby/3.1/sbin --libdir=/usr/ruby/3.1/lib/amd64 --with-rubylibprefix=/usr/ruby/3.1/lib/ruby --enable-shared --enable-rpath /usr/bin/make -j 16 -l 32 objdump -x ./.ext/x86_64-linux/enc/windows_31j.so | grep RPATH ``` While previously this resulted in the following output: `RPATH /usr/ruby/3.1/lib/amd64` in 3.1.3 it is wrongly set to the build directory: `RPATH /home/jkulik/rubytest/ruby-3.1.3` I tried looking for some obvious change but didn't find the core of this issue yet. All I found out is that generated `enc.mk` differs in `prefix` and `libdir` ``` -prefix = /usr/ruby/3.1 +prefix = /home/jkulik/rubytest/ruby-3.1.3 exec_prefix = $(prefix) -libdir = $(exec_prefix)/lib/amd64 +libdir = /home/jkulik/rubytest/ruby-3.1.3 ``` `rbconfig.rb` is similar in both versions, but when I print out `CONFIG` in `make_encmake.rb` right after `load File.expand_path("lib/mkmf.rb", dir)`, I can see the differences from above, so it's probably something in the `lib/mkmf.rb` file that changes that. I am seeing the same issue in the current latest ruby 3.1 branch cloned from github. -- https://bugs.ruby-lang.org/
