Issue #20397 has been reported by vo.x (Vit Ondruch). ---------------------------------------- Bug #20397: The nkf license in LEGAL file seems to be obsolete https://bugs.ruby-lang.org/issues/20397 * Author: vo.x (Vit Ondruch) * Status: Open * ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- The LEGAL file seems to contain [obsolete information](https://github.com/ruby/ruby/blob/a69f0047cb489c136001937442c1… about nkf license. It seems that nkf indeed use such license, but in upstream, it was first changed to [MIT](https://github.com/nurse/nkf/commit/c12280757bfb275d6f9e6b0bf6293a28b0… and then immediately to [zlib](https://github.com/nurse/nkf/commit/2ed3e1c270f1deb9487f7bc7d7586030f… license. Ruby has picked up that change with commit:git|13313688b243882aff7815598ddd9fcbae69bc17 Maybe @naruse can comment about this. -- https://bugs.ruby-lang.org/

Issue #19056 has been updated by ioquatix (Samuel Williams). Status changed from Assigned to Closed I released this as a gem. https://github.com/ioquatix/fiber-annotation Maybe it can be adopted if it proves itself to be useful. ---------------------------------------- Feature #19056: Introduce `Fiber.annotation` for attaching messages to fibers. https://bugs.ruby-lang.org/issues/19056#change-107880 * Author: ioquatix (Samuel Williams) * Status: Closed * Assignee: ioquatix (Samuel Williams) ---------------------------------------- It's useful to know what a fiber is doing especially when they have a temporal execution (i.e. sockets connecting vs connected, binding vs accepting, queue popping, etc) Let's introduce `Fiber.annotate` and `Fiber#annotation` for logging a short message attached to Fibers. ```ruby Fiber.annotate "Counting to 10" 10.times{|I| puts I} # Fiber.current.annotation => "Counting to 10" ``` Pull Request: https://github.com/ruby/ruby/pull/6554 ---Files-------------------------------- clipboard-202210160132-n7lzp.png (865 KB) -- https://bugs.ruby-lang.org/

However, you can clearly see from the order of the sample code it's not possible for such an error to occur. `#close` is only invoked after a successful `#read` which is only possible after a successful `#write`. Yet, the error implies that the write failed because it was already closed. -- https://bugs.ruby-lang.org/

[ruby-core:117487] [Ruby master Bug#18455] `IO#close` has poor performance and difficult to understand semantics.

Issue #18455 has been updated by ioquatix (Samuel Williams). Assignee set to ioquatix (Samuel Williams) ---------------------------------------- Bug #18455: `IO#close` has poor performance and difficult to understand semantics. https://bugs.ruby-lang.org/issues/18455#change-107877 * Author: ioquatix (Samuel Williams) * Status: Open * Assignee: ioquatix (Samuel Williams) * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- `IO#close` should be responsible for closing the file descriptor referred to by the IO instance. When dealing with buffered IO, one can also expect this to flush the internal buffers if possible. Currently, all blocking IO operations release the GVL and perform the blocking system call using `rb_thread_io_blocking_region`. The current implementation takes a file descriptor and adds an entry to the VM global `waiting_fds` list. When the operation is completed, the entry is removed from `waiting_fds`. When calling `IO#close`, this list is traversed and any threads performing blocking operations with a matching file descriptor are interrupted. The performance of this is O(number of blocking IO operations) which in practice the performance of `IO#close` can take milliseconds with 10,000 threads performing blocking IO. This performance is unacceptable. ``` ruby #!/usr/bin/env ruby require 'benchmark' class Reading def initialize @r, @w = IO.pipe @thread = Thread.new do @r.read rescue IOError # Ignore. end end attr :r attr :w attr :thread def join @thread.join end end def measure(count = 10) readings = count.times.map do Reading.new end sleep 10 duration = Benchmark.measure do readings.each do |reading| reading.r.close reading.w.close end end average = (duration.total / count) * 1000.0 pp count: count, average: sprintf("%0.2fms", average) readings.each(&:join) end measure( 10) measure( 100) measure( 1000) measure(10000) ``` In addition, the semantics of this operation are confusing at best. While Ruby programs are dealing with IO instances, the VM is dealing with file descriptors, in effect performing some internal de-duplication of IO state. In practice, this leads to strange behaviour: ``` ruby #!/usr/bin/env ruby r, w = IO.pipe r2 = IO.for_fd(r.to_i) pp r: r, r2: r2 t = Thread.new do r2.read rescue nil r2.read # EBADF end sleep 0.5 r.close t.join rescue nil pp r: r, r2: r2 # r is closed, r2 is valid but will raise EBADF on any operation. ``` In addition, this confusing behaviour extends to Ractor and state is leaked between the two: ``` ruby r, w = IO.pipe ractor = Ractor.new(r.to_i) do |fd| r2 = IO.for_fd(fd) r2.read # r2.read # EBADF end sleep 0.5 r.close pp take: ractor.take ``` I propose the following changes to simplify the semantics and improve performance: - Move the semantics of `waiting_fds` from per-fd to per-IO. This means that `IO#close` only interrupts blocking operations performed on the same IO instance rather than ANY IO which refers to the same file descriptor. I think this behaviour is easier to understand and still protects against the vast majority of incorrect usage. - Move the details of `struct rb_io_t` to `internal/io.h` so that the implementation details are not part of the public interface. ## Benchmarks Before: ``` {:count=>10, :average=>"0.19ms"} {:count=>100, :average=>"0.11ms"} {:count=>1000, :average=>"0.18ms"} {:count=>10000, :average=>"1.16ms"} ``` After: ``` {:count=>10, :average=>"0.20ms"} {:count=>100, :average=>"0.11ms"} {:count=>1000, :average=>"0.15ms"} {:count=>10000, :average=>"0.68ms"} ``` After investigating this further I found that the `rb_thread_io_blocking_region` using `ubf_select` can be incredibly slow, proportional to the number of threads. I don't know whether it's advisable but: ``` c BLOCKING_REGION(blocking_node.thread, { val = func(data1); saved_errno = errno; }, NULL /* ubf_select */, blocking_node.thread, FALSE); ``` Disabling the UBF function and relying on `read(fd, ...)`/`write(fd, ...)` blocking operations to fail when `close(fd)` is invoked might be sufficient? This needs more investigation but after making this change, we have constant-time IO#close. ``` {:count=>10, :average=>"0.13ms"} {:count=>100, :average=>"0.06ms"} {:count=>1000, :average=>"0.04ms"} {:count=>10000, :average=>"0.09ms"} ``` Which is ideally what we want. -- https://bugs.ruby-lang.org/

[ruby-core:117484] [Ruby master Feature#18915] New error class: NotImplementedYetError or scope change for NotImplementedError
by nithinbekal (Nithin Bekal) 10 Apr '24

10 Apr '24

Issue #18915 has been updated by nithinbekal (Nithin Bekal). > What name candidate do you have? What do you think about the name `SubclassResponsibilityError`? As @citizen428 explains [here](https://ruby.social/@citizen428@chaos.social/112239323523258221): > Smalltalk had the idiom of implementing abstract methods with the body `self subclassResponsibility` which raises an error. The name gives a pretty clear indication of what is wrong, and it seems fitting considering Ruby's Smalltalk heritage. ---------------------------------------- Feature #18915: New error class: NotImplementedYetError or scope change for NotImplementedError https://bugs.ruby-lang.org/issues/18915#change-107873 * Author: Quintasan (Michał Zając) * Status: Open ---------------------------------------- # Abstract Introduce `NotImplementedYetError` exception that should be used in case when the codepath has not been implemented by the developer for some reason (maybe they're designing an abstract class or are designing some sort of interface to reuse later on) OR extend the meaning of `NotImplementedError` to cover those usecases so we don't have to introduce another exception # Background `NotImplementedError` is supposed to be raised `if the underlying operating system or Ruby runtime does not support them` (https://ruby-doc.org/core-3.1.2/NotImplementedError.html) However it appears that many people are misusing this exception by raising this in a superclass from which they later inherit from. I do realize that Ruby promotes duck-typing (the default RuboCop style guide has a cop for this – https://github.com/rubocop/ruby-style-guide#duck-typing) However I have seen this being discussed numerous times: * https://github.com/rubocop/ruby-style-guide/issues/458 * http://chrisstump.online/2016/03/23/stop-abusing-notimplementederror/ * https://oleg0potapov.medium.com/ruby-notimplementederror-dont-use-it-dff1fd… * https://gitlab.com/gitlab-org/gitlab/-/issues/354314 (which I'm the author of) * https://github.com/rmosolgo/graphql-ruby/issues/2067 (here the author actually confused it with Python's `NotImplementedError`) * https://stackoverflow.com/questions/13668068/how-to-signal-not-implemented-… # Proposal Create `NotImplementedYetError` exception OR Allow raising `NotImplementedError` in cases other than OS or Ruby runtime incompatibilities # Evaluation ### Add `NotImplementedYetError` I think a new exception is a better idea than changing the usage of an existing one just because "everyone is using it". That said it would require people to refactor their code which might prevent wider adoption of the new exception. ### Change scope of `NotImplementedError` This would require the least amount of changes possible (only a documentation change) and I believe there would be no compatibility problems whatsoever. ---Files-------------------------------- not-implemented-error-docs.patch (1.57 KB) -- https://bugs.ruby-lang.org/

[ruby-core:117481] [Ruby master Bug#18993] Inconsistent Range#size for Float and Rational
by jeremyevans0 (Jeremy Evans) 09 Apr '24

09 Apr '24

Issue #18993 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Open to Closed This appears fixed in Ruby 3.3: ``` $ ruby32 -ve "p (5.quo(3)...5).size" ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [x86_64-openbsd] 3 $ ruby33 -ve "p (5.quo(3)...5).size" ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-openbsd] 4 ``` ---------------------------------------- Bug #18993: Inconsistent Range#size for Float and Rational https://bugs.ruby-lang.org/issues/18993#change-107868 * Author: masasakano (Masa Sakano) * Status: Closed * ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-darwin20] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- The returned values of Range#size between Rational and Float and also with regard to `exclude_end` of true and false are inconsistent. The example below highlights the difference. The first and second should return the same value. The difference between the first and third seems strange - if this is the specification, it should be clearly described in the [doc](https://ruby-doc.org/core-3.1.2/Range.html#method-i-size "Ruby-3.1.2 official doc of Range"). This point may be related to the issue "Misc #18984". ```ruby (5.quo(3)...5).size # => 3 (5.quo(3).to_f...5).size # => 4 (5.quo(3)..5).size # => 4 (5.quo(3).to_f..5).size # => 4 ``` -- https://bugs.ruby-lang.org/

[ruby-core:117121] [Ruby master Bug#20332] AFter upgrading to ruby v 3.2.3 rb_scan_args() skips argument value
by praveenrocket (Praveen N) 09 Apr '24

Issue #20332 has been reported by praveenrocket (Praveen N). ---------------------------------------- Bug #20332: AFter upgrading to ruby v 3.2.3 rb_scan_args() skips argument value https://bugs.ruby-lang.org/issues/20332 * Author: praveenrocket (Praveen N) * Status: Open * ruby -v: 3.2.3 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- Hi, Note: I am not an expert at ruby. I am working on ibm_db gem, its an adapter developed using ruby C extension, which helps ruby & rails applications to connect to DB2 database. Here is a github link for its source https://github.com/ibmdb/ruby-ibmdb/tree/master As of now ibm_db gem is compatible with ruby v 3.1. Now I am trying to make ibm_db gem compatible with ruby v 3.2.3. All my test cases were working for ruby v 3.1, but post upgrading to ruby v 3.2.3, most of my test cases are failing. After debugging using gdb what I see is, my ruby test cases calls ruby C extension API passing required arguments, but inside C extension code arguments are not parsed, indeed nothing is read. Because of this most of test cases are failing. Below is a sample ruby script which when run calls ibm_db extension, `$ irb irb(main):001:0> require 'ibm_db' => true irb(main):002:0> conn = IBM_DB.connect("DATABASE=sample;HOSTNAME=waldevdbclnxtst06.dev.rocketsoftware.com;PORT=60000;PROTOCOL=TCPIP;UID=zurbie;PWD=A2m8test;",'','') (irb):2: warning: undefining the allocator of T_DATA class IBM_DB::Connection => #<IBM_DB::Connection:0x00007ff60314ce58> irb(main):003:0> stmt = IBM_DB.exec conn,'create table abc(C1 int)' => false irb(main):004:0> irb(main):005:0> IBM_DB.close(conn) => true irb(main):006:0> exit ` Above, If you observe IBM_DB.exec is called passing two arguments conn & string with create table query. In extension code https://github.com/ibmdb/ruby-ibmdb/blob/master/IBM_DB_Driver/ibm_db.c, below function will be called VALUE ibm_db_exec(int argc, VALUE *argv, VALUE self) { .... rb_scan_args(argc, argv, "21", &connection, &stmt, &options); ...... } Note: Please refer https://github.com/ibmdb/ruby-ibmdb/blob/master/IBM_DB_Driver/ibm_db.c for complete code. rb_scan_args used to parse arguments very well in ruby v 3.1, but now its failing to do so. I see stmt parameter doesnt hold anything. I just want to know whats issue here, Am I passing arguments in wrong way (in ruby script), or am I not using rb_scan_args properly ? To reproduce, Install ruby v 3.2.3, Install ibm_db gem version 5.4.1 (latest) Run above sample ruby script using IRB. Response at earliest is much appreciated. Thanks Praveen -- https://bugs.ruby-lang.org/
