[ruby-core:111610] [Ruby master Bug#19305] TracePoint#parameters segfaults when certain method creation pattern is used

Issue #19305 has been reported by st0012 (Stan Lo). ---------------------------------------- Bug #19305: TracePoint#parameters segfaults when certain method creation pattern is used https://bugs.ruby-lang.org/issues/19305 * Author: st0012 (Stan Lo) * Status: Open * Priority: Normal * ruby -v: 3.2.0, 3.1.3 * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- ### Reproduction Steps 1. Create a `test.rb` with: ``` class Foo attr_reader :bar alias_method :bar?, :bar remove_method :bar end f = Foo.new TracePoint.trace(:a_call) do |tp| puts tp.method_id puts tp.parameters end f.bar? ``` 2. Run `ruby test.rb` 3. Ruby would crash (an example crash report is attached below) ### Implication I learned this pattern from the [bootsnap gem](https://github.com/Shopify/bootsnap). It defines `Bootsnap::LoadPathCache.enabled?` this way, which is used to patch [`Kernel.require`](https://github.com/Shopify/bootsnap/blob/main/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb#L9). This means when users use `bootsnap` (likely a Rails app) with `TracePoint#parameters` (e.g. uses the [debug gem's tracer](https://github.com/ruby/debug/blob/master/lib/debug/tracer.rb#L204)) Ruby would crash whenever `require` is called. ### Crash Report ``` <internal:trace_point>:329: [BUG] Segmentation fault at 0x0000000000000010 ruby 3.2.0 (2022-12-25 revision a528908271) [arm64-darwin21.5.0] -- Crash Report log information -------------------------------------------- See Crash Report log file in one of the following locations: * ~/Library/Logs/DiagnosticReports * /Library/Logs/DiagnosticReports for more details.

[ruby-core:112457] [Ruby master Feature#19443] Cache `Process.pid`
by byroot (Jean Boussier) 20 Mar '23

20 Mar '23

Issue #19443 has been reported by byroot (Jean Boussier). ---------------------------------------- Feature #19443: Cache `Process.pid` https://bugs.ruby-lang.org/issues/19443 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- It's not uncommon for database client and similar network libraries to protect themselves from Process.fork by regularly checking Process.pid Until recently most libc would cache `getpid()` so this was a cheap check to make. However as of glibc version 2.25 the PID cache is removed and calls to `getpid()` always invoke the actual system call which significantly degrades the performance of existing applications. The reason glibc removed the cache is that some libraries were bypassing `fork(2)` by issuing system calls themselves, causing stale cache issues. That isn't a concern for Ruby as bypassing MRI's primitive for forking would render the VM unusable, so we can safely cache the PID. An example of the issue: https://github.com/rails/rails/issues/47418 -- https://bugs.ruby-lang.org/

[ruby-core:112634] [Ruby master Bug#19469] Crash when resizing generic iv list
by peterzhu2118 (Peter Zhu) 18 Mar '23

Issue #19469 has been reported by peterzhu2118 (Peter Zhu). ---------------------------------------- Bug #19469: Crash when resizing generic iv list https://bugs.ruby-lang.org/issues/19469 * Author: peterzhu2118 (Peter Zhu) * Status: Open * Priority: Normal * Backport: 2.7: DONTNEED, 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED ---------------------------------------- GitHub PR: https://github.com/ruby/ruby/pull/7407 The following script can sometimes trigger a crash: ```ruby GC.stress = true class Array def foo(bool) if bool @a = 1 @b = 2 @c = 1 else @c = 1 end end end obj = [] obj.foo(true) obj2 = [] obj2.foo(false) obj3 = [] obj3.foo(true) ``` This is because vm_setivar_default calls rb_ensure_generic_iv_list_size to resize the iv list. However, the call to gen_ivtbl_resize reallocs the iv list, and then inserts into the generic iv table. If the st_insert triggers a GC then the old iv list will be read during marking, causing a use-after-free bug. -- https://bugs.ruby-lang.org/

by romuloceccon 17 Mar '23

17 Mar '23

Issue #19468 has been reported by romuloceccon (Rômulo Ceccon). ---------------------------------------- Bug #19468: Ruby 3.2: net/http sets UTF-8 encoding for binary responses https://bugs.ruby-lang.org/issues/19468 * Author: romuloceccon (Rômulo Ceccon) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.1 (2023-02-22 revision 65ab2c1ef2) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- net/http on Ruby 3.2 has changed the encoding of binary responses from SSL connected hosts (non-SSL connections are not affected): ``` ruby # req.rb require 'openssl' require 'net/http' puts "openssl ext: #{OpenSSL::VERSION}" puts "openssl lib: #{OpenSSL::OPENSSL_VERSION}" puts "net-protocol: #{Net::Protocol::VERSION}" puts "net-http: #{Net::HTTP::VERSION}" puts Net::HTTP.get(URI(ARGV.first)).encoding ``` Ruby 3.1 (with updated net-protocol and net-http libs): ``` $ ruby -v ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux] $ ruby req.rb https://www.gnu.org/software/gzip/manual/gzip.pdf openssl ext: 3.0.0 openssl lib: OpenSSL 1.1.1n 15 Mar 2022 net-protocol: 0.2.1 net-http: 0.3.2 ASCII-8BIT # <== CORRECT ``` Ruby 3.2 (latest git revision): ``` $ ruby -v ruby 3.2.1 (2023-02-22 revision 65ab2c1ef2) [x86_64-linux] $ ruby req.rb https://www.gnu.org/software/gzip/manual/gzip.pdf openssl ext: 3.1.0 openssl lib: OpenSSL 1.1.1n 15 Mar 2022 net-protocol: 0.2.1 net-http: 0.3.2 UTF-8 # <== WRONG ``` I've tracked the problem down to the SSL socket call at https://github.com/ruby/ruby/blob/9557c8edf2dcf18fdece066c596a71696b2f2b30/…. The string returned has the encoding set to `ASCII-8BIT`, but `#ascii_only?` also always reports true, even when there are non-ascii bytes. This seems to be a bug, and is the probably cause of the change in behavior in net/http. On Ruby 3.1 concatenating the result of reading the SSL socket to a UTF-8 string produces an ASCII-8BIT string. On Ruby 3.2 the concatenation produces a UTF-8 string. Here's a program demonstrating the behavior of the SSL socket: ```ruby # ssltest.rb require 'openssl' require 'uri' url = URI(ARGV.first) path = url.path path += '?' + url.query if url.query req = "GET #{path} HTTP/1.1\r\nHost: #{url.hostname}\r\nAccept: */*\r\n\r\n" sock = OpenSSL::SSL::SSLSocket.open(url.hostname, url.port || HTTPS.default_https_port) sock.connect sock.write(req) sleep(1) loop do sleep(0.1) b = ''.b r = sock.read_nonblock(1024 * 16, b, exception: false) break unless String === r p [r.bytesize, r.encoding.to_s, r.ascii_only?] end ``` Ruby 3.1: ``` $ ruby ssltest.rb https://www.gnu.org/software/gzip/manual/gzip.pdf [475, "ASCII-8BIT", true] [16384, "ASCII-8BIT", false] # <== always false (except HTTP header): CORRECT [16384, "ASCII-8BIT", false] ... [13927, "ASCII-8BIT", false] ``` Ruby 3.2: ``` $ ruby ssltest.rb https://www.gnu.org/software/gzip/manual/gzip.pdf [475, "ASCII-8BIT", true] [16384, "ASCII-8BIT", true] # <== always true: WRONG [16384, "ASCII-8BIT", true] ...

[ruby-core:112213] [Ruby master Bug#19412] Socket starts queueing and not responding after a certain amount of requests

Issue #19412 has been reported by brodock (Gabriel Mazetto). ---------------------------------------- Bug #19412: Socket starts queueing and not responding after a certain amount of requests https://bugs.ruby-lang.org/issues/19412 * Author: brodock (Gabriel Mazetto) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Here is a an example code: ``` require 'socket' PORT = 8080 BACKLOG = 50 LISTEN = '127.0.0.1' def handle_connection(connection, _addrinfo) request = connection.gets puts request connection.write "HTTP/1.1 200\r\n" connection.write "Content-Type: text/html\r\n" connection.write "\r\n" connection.write "Hello world! Current time is #{Time.now}" ensure connection.close end begin socket = Socket.new(:INET, :STREAM) socket.bind(Addrinfo.tcp(LISTEN, PORT)) socket.listen(BACKLOG) puts "Requested queue size: #{BACKLOG} bigger then limit: #{Socket::SOMAXCONN}" if BACKLOG > Socket::SOMAXCONN loop do listening, = IO.select([socket]) io, = listening connection, addrinfo = io.accept handle_connection(connection, addrinfo) end ensure socket.close end ``` This tries to simulate a TCP server that responds as if it was an HTTP server. The amount of requests it can sustain seems to depend on the OS. On a Linux machine running ubuntu 20.04 I get something around 7.6K to 7.8K until it stops responding. ``` $ uname -a Linux ... 5.17.5-x86_64-linode154 #1 SMP PREEMPT Mon May 2 15:07:22 EDT 2022 x86_64 x86_64 x86_64 GNU/Linux $ ab -n 20000 -c 50 http://127.0.0.1:8080/ This is ApacheBench, Version 2.3 <$Revision: 1843412 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking 127.0.0.1 (be patient) Completed 2000 requests Completed 4000 requests Completed 6000 requests apr_pollset_poll: The timeout specified has expired (70007) Total of 7883 requests completed ``` on MacOS Ventura I get around 16K: ``` $ uname -a Darwin ... 22.2.0 Darwin Kernel Version 22.2.0: Fri Nov 11 02:04:44 PST 2022; root:xnu-8792.61.2~4/RELEASE_ARM64_T8103 arm64 $ ab -n 20000 -c 50 http://127.0.0.1:8080/ This is ApacheBench, Version 2.3 <$Revision: 1901567 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking 127.0.0.1 (be patient) Completed 2000 requests Completed 4000 requests Completed 6000 requests Completed 8000 requests Completed 10000 requests Completed 12000 requests Completed 14000 requests Completed 16000 requests apr_socket_recv: Operation timed out (60) Total of 16375 requests completed ``` in both cases when that limit reaches, if I abort the program (CTRL-C) and try to run it again it takes a while until the port is released: ``` ... GET / HTTP/1.0 GET / HTTP/1.0 GET / HTTP/1.0 ^Csocketserver.rb:29:in `select': Interrupt from socketserver.rb:29:in `block in <main>' from socketserver.rb:28:in `loop' from socketserver.rb:28:in `<main>' $ ruby socketserver.rb socketserver.rb:23:in `bind': Address already in use - bind(2) for 127.0.0.1:8080 (Errno::EADDRINUSE) from socketserver.rb:23:in `<main>' ``` After killing the process it seems no process is holding the port: ``` lsof -wni tcp:8080 ``` Running the command above does not return anything (it does when the program is still running). I think we may be failing to release something when interacting with the Socket on syscalls/kernel level and we endup filling up some queue/buffer that eventually gets freed. -- https://bugs.ruby-lang.org/

[ruby-core:112541] [Ruby master Bug#19459] Is `length` of `IO::Buffer#read` required or optional?

Issue #19459 has been reported by nobu (Nobuyoshi Nakada). ---------------------------------------- Bug #19459: Is `length` of `IO::Buffer#read` required or optional? https://bugs.ruby-lang.org/issues/19459 * Author: nobu (Nobuyoshi Nakada) * Status: Assigned * Priority: Normal * Assignee: ioquatix (Samuel Williams) * Backport: 2.7: DONTNEED, 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED ---------------------------------------- io_buffer.c has warnings. http://ci.rvm.jp/logfiles/brlog.trunk-asserts.20230222-105209#L956 ``` /tmp/ruby/src/trunk-asserts/io_buffer.c: In function 'io_buffer_read': /tmp/ruby/src/trunk-asserts/io_buffer.c:2468:12: warning: 'length' may be used uninitialized in this function [-Wmaybe-uninitialized] 2468 | return rb_io_buffer_read(self, io, length, offset); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /tmp/ruby/src/trunk-asserts/io_buffer.c: In function 'io_buffer_write': /tmp/ruby/src/trunk-asserts/io_buffer.c:2681:12: warning: 'length' may be used uninitialized in this function [-Wmaybe-uninitialized] 2681 | return rb_io_buffer_write(self, io, length, offset); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /tmp/ruby/src/trunk-asserts/io_buffer.c: At top level: cc1: note: unrecognized command-line option '-Wno-self-assign' may have been intended to silence earlier diagnostics cc1: note: unrecognized command-line option '-Wno-parentheses-equality' may have been intended to silence earlier diagnostics cc1: note: unrecognized command-line option '-Wno-constant-logical-operand' may have been intended to silence earlier diagnostics ``` As the `argc` is checked already as `rb_check_arity(argc, 2, 3)`, `length` is a required argument. This means the condition `if (argc >= 2)` is always true and unnecessary, then `length` is initialized. However, in the rdoc of `io_buffer_read`, which has been added at 3.2, states `length` is optional. ```c * call-seq: read(io, [length, [offset]]) -> read length or -errno * * Read at most +length+ bytes from +io+ into the buffer, starting at * +offset+. If an error occurs, return <tt>-errno</tt>. * * If +length+ is not given, read until the end of the buffer. ``` Which is correct? -- https://bugs.ruby-lang.org/

[ruby-core:112438] [Ruby master Feature#19440] Deprecate ThreadGroup

Issue #19440 has been reported by Eregon (Benoit Daloze). ---------------------------------------- Feature #19440: Deprecate ThreadGroup https://bugs.ruby-lang.org/issues/19440 * Author: Eregon (Benoit Daloze) * Status: Open * Priority: Normal ---------------------------------------- I looked at the ThreadGroup methods, and none of them seem really useful. `enclose` has super confusing semantics, in that it surprisingly allows creating new threads from a thread already in that group, but forbids `#add`. So the new thread is not the same as "adding" a thread, very confusing. This weird restriction results for instance in `Timeout` not being able to move the Thread it creates to the default ThreadGroup: https://github.com/ruby/timeout/issues/24 And there is also no method to create a Thread in the given ThreadGroup. `add` and `list` could just be simulated with an Array. Maybe it's time we deprecate ThreadGroup or at least `enclose`/`enclosed?` since those seem to have unusable/useless semantics? If not, how do we cleanly solve https://github.com/ruby/timeout/issues/24? -- https://bugs.ruby-lang.org/
