[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.

This works fine: ``` puts <<' ABC' marker with spaces ABC ``` But this is not: ``` puts <<-' ABC' marker with spaces ABC ``` as well as ``` puts <<~' ABC' marker with spaces ABC ``` I would expect it to wok properly, even in case: ``` puts <<-' ABC' marker with spaces ABC ``` -- https://bugs.ruby-lang.org/

[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/

Issue #18743 has been updated by marcper (Marcelo Pereira). Hello again. I've modified the patch to also link to the old exception via `cause`. Let me know if it's now a reasonable solution. Thanks, Marcelo ---------------------------------------- Bug #18743: Enumerator#next / peek re-use each others stacktraces https://bugs.ruby-lang.org/issues/18743#change-102465 * Author: sos4nt (Stefan Schüßler) * Status: Open * Priority: Normal * Assignee: ko1 (Koichi Sasada) * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- I encountered an odd behavior. If I rescue the `StopIteration` exception from `peek` and call `next` afterwards: (or vice-versa) ```ruby # enum.rb # 1 # 2 enum = [].each # 3 enum.peek rescue nil # 4 enum.next # 5 ``` it will show the stacktrace from the rescued `peek` call: ``` $ ruby enum.rb enum.rb:4:in `peek': iteration reached an end (StopIteration) from enum.rb:4:in `<main>' ``` Whereas the error should refer to `next` on line number 5. The same happens when calling `peek` after `next` or when having muliple `peek` / `next` calls: ```ruby # enum.rb # 1 # 2 enum = [].each # 3 enum.peek rescue nil # 4 enum.next rescue nil # 5 enum.peek rescue nil # 6 puts "line #{__LINE__}" # 7 enum.next # 8 ``` The stacktrace from the first (rescued) `peek` or `next` call will be shown which doesn't reflect the actual error location: ``` $ ruby enum.rb line 7 enum.rb:4:in `peek': iteration reached an end (StopIteration) from enum.rb:4:in `<main>' ``` This is very confusing when debugging code. ---Files-------------------------------- 01-Recreate-stacktrace-enumerator.patch (1.29 KB) -- https://bugs.ruby-lang.org/

[ruby-core:112634] [Ruby master Bug#19469] Crash when resizing generic iv list

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/

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] ... [13927, "ASCII-8BIT", true] ``` -- https://bugs.ruby-lang.org/

[ruby-core:112924] [Ruby master Bug#18580] Range#include? inconsistency for beginless String ranges
by mame (Yusuke Endoh) 17 Mar '23

17 Mar '23

Issue #18580 has been updated by mame (Yusuke Endoh). Unfortunately, this change broke an existing program: #19533. The lesson here is that it would be best to avoid changing any behavior just for the sake of consistency unless it is proven that the behavior actually confuses a large number of people. ---------------------------------------- Bug #18580: Range#include? inconsistency for beginless String ranges https://bugs.ruby-lang.org/issues/18580#change-102445 * Author: zverok (Victor Shepelev) * Status: Closed * Priority: Normal * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- The follow-up of #18577. `Range#include?` is [specialized for strings](https://github.com/ruby/ruby/blob/master/range.c#L1782). For all I can tell, this behavior is relatively new: it emerged when switching `#===` to use `#cover?` instead of `#include?`: * in 2.6, it was decided that String Ranges should continue to use `#include?` (#14575) * ...but in 2.7, it was decided that they should use `#cover?` as all others (#15449) The "despecialization" in 2.7 was actually done by adding more specialization in `range_include_internal`. This leads to the following: ```ruby # default Range behavior: (..Date.today).include? Date.today # (irb):10:in `each': can't iterate from NilClass (TypeError) # String Range behavior: (..'z').include?('w') # => true ``` Why I think **it is bad**: 1. This is a leftover of the relatively recent change; why it is 3 versions old, I doubt there is a lot of code relying on this quirk (only beginless ranges are affected) 2. The more "invisible specialization", the more possibility of bugs (as #18577 shows) 3. It is easy to stumble upon while learning Ruby/experimenting (strings and ranges are the most basic objects to be seen in many examples and courses), and to become confused, because there is no reasonable explanation for the semantics other than "well... for String, it is so" 4. It *can* be said that the String ranges behavior have the same specialization as Numeric ones, but it is not so; while Numeric Ranges specialization is long-living legacy, it is at least consistent (`#include?` just behaves like `#cover?` for them, always): Numerics: ```ruby (1...3).include? 1.5 # => true, like #cover? (...3).include? 1.5 # => true, same, the explanation is "just like #cover?" ``` Strings: ```ruby ('a'..'z').include?('ww') # => false, like #include? for any other type (..'z').include?('ww') # => true, this is deeply confusing ``` -- https://bugs.ruby-lang.org/
