Only ivar reader and writer methods should need the shape ID set on the
inline cache. We shouldn't accidentally overwrite parts of the CC union
when it's not necessary.

Use plain paragraphs instead of a nested unordered list.
Remove some examples, including examples that produce warnings in
verbose mode or raise exceptions.
Explicitly document the common pitfall of using an expression as a
default value instead of using a block.
These files were to build libffi from the bundled source, but are no
longer used since we stopped bundling the libffi sources in commit
e4f5296f065110fa83eb450d3a861253e76e534f.
The gemspec file is unchanged because fiddle gem itself still supports
ruby 2.5.
[Bug #20654]
This commit fixes Integer#ceil and Float#ceil when the number is
negative and ndigits is large such that 10**ndigits is a bignum.
Previously, it would return 0 in such cases. However, this would cause
unexpected behaviour such as:
puts 1.ceil(-5) # => 100000
puts 1.ceil(-10) # => 10000000000
puts 1.ceil(-20) # => 0
This commit changes the last result so that it will return
100000000000000000000.
[Bug #20654]
This commit fixes Integer#floor and Float#floor when the number is
negative and ndigits is large such that 10**ndigits is a bignum.
Previously, it would return 0 in such cases. However, this would cause
unexpected behaviour such as:
puts -1.floor(-5) # => -100000
puts -1.floor(-10) # => -10000000000
puts -1.floor(-20) # => 0
This commit changes the last result so that it will return
-100000000000000000000.
28a1c4f33e3349a98c04b8e068d9c674eb936064 seems to call an improper
ensure clause. [Bug #20655]
Than fixing it properly, I bet it would be much better to simply revert
that commit. It reduces the unneeded complexity. Jumping into a block
called by a C function like Hash#each with callcc is user's fault.
It does not need serious support.
[Feature #20646]Improve Socket.tcp
This is a proposed improvement to `Socket.tcp`, which has implemented Happy Eyeballs version 2 (RFC8305) in PR9374.
1. Background
I implemented Happy Eyeballs version 2 (HEv2) for Socket.tcp in PR9374, but several issues have been identified:
- `IO.select` waits for name resolution or connection establishment in v46w, but it does not consider the case where both events occur simultaneously when it returns a value.
- In this case, Socket.tcp can only capture one event and needs to execute an unnecessary loop to capture the other one, calling `IO.select` one extra time.
- `IO.select` waits for both IPv6/IPv4 name resolution (in start), but when it returns a value, it doesn't consider the case where name resolution for both address families is complete.
- In this case, `Socket.tcp` can only obtain the addresses of one address family and needs to execute an unnecessary loop obtain the other addresses, calling `IO.select` one extra time.
- The consideration for `connect_timeout` was insufficient. After initiating one or more connections, it raises a 'user specified timeout' after the `connect_timeout` period even if there were addresses that have been resolved and have not yet tried to connect.
- It does not retry with another address in case of a connection failure.
- It executes unnecessary state transitions even when an IP address is passed as the `host` argument.
- The regex for IP addresses did not correctly specify the start and end.
2. Proposal & Outcome
To overcome the aforementioned issues, this PR introduces the following changes:
- Previously, each loop iteration represented a single state transition. This has been changed to execute all processes that meet the execution conditions within a single loop iteration.
- This prevents unnecessary repeated loops and calling `IO.select`
- Introduced logic to determine the timeout value set for `IO.select`. During the Resolution Delay and Connection Attempt Delay, the user-specified timeout is ignored. Otherwise, the timeout value is set to the larger of `resolv_timeout` and `connect_timeout`.
- This ensures that the `connect_timeout` is only detected after attempting to connect to all resolved addresses.
- Retry with another address in case of a connection failure.
- This prevents unnecessary repeated loops upon connection failure.
- Call `tcp_without_fast_fallback` when an IP address is passed as the host argument.
- This prevents unnecessary state transitions when an IP address is passed.
- Fixed regex for IP addresses.
Additionally, the code has been reduced by over 100 lines, and redundancy has been minimized, which is expected to improve readability.
3. Performance
No significant performance changes were observed in the happy case before and after the improvement.
However, improvements in state transition deficiencies are expected to enhance performance in edge cases.
```ruby
require 'socket'
require 'benchmark'
Benchmark.bmbm do |x|
x.report('fast_fallback: true') do
30.times { Socket.tcp("www.ruby-lang.org", 80) }
end
x.report('fast_fallback: false') do # Ruby3.3時点と同じ
30.times { Socket.tcp("www.ruby-lang.org", 80, fast_fallback: false) }
end
end
```
Before:
```
~/s/build ❯❯❯ ../install/bin/ruby ../ruby/test.rb
user system total real
fast_fallback: true 0.021315 0.040723 0.062038 ( 0.504866)
fast_fallback: false 0.007553 0.026248 0.033801 ( 0.533211)
```
After:
```
~/s/build ❯❯❯ ../install/bin/ruby ../ruby/test.rb
user system total real
fast_fallback: true 0.023081 0.040525 0.063606 ( 0.406219)
fast_fallback: false 0.007302 0.025515 0.032817 ( 0.418680)
