[Bug #20649] Allow `nil` as 2nd argument of `assign_error`
Fallback to the last token element in that case, for the backward
compatibilities.
|
|
Our current implementation of rb_postponed_job_register suffers from
some safety issues that can lead to interpreter crashes (see bug #1991).
Essentially, the issue is that jobs can be called with the wrong
arguments.
We made two attempts to fix this whilst keeping the promised semantics,
but:
* The first one involved masking/unmasking when flushing jobs, which
was believed to be too expensive
* The second one involved a lock-free, multi-producer, single-consumer
ringbuffer, which was too complex
The critical insight behind this third solution is that essentially the
only user of these APIs are a) internal, or b) profiling gems.
For a), none of the usages actually require variable data; they will
work just fine with the preregistration interface.
For b), generally profiling gems only call a single callback with a
single piece of data (which is actually usually just zero) for the life
of the program. The ringbuffer is complex because it needs to support
multi-word inserts of job & data (which can't be atomic); but nobody
actually even needs that functionality, really.
So, this comit:
* Introduces a pre-registration API for jobs, with a GVL-requiring
rb_postponed_job_prereigster, which returns a handle which can be
used with an async-signal-safe rb_postponed_job_trigger.
* Deprecates rb_postponed_job_register (and re-implements it on top of
the preregister function for compatability)
* Moves all the internal usages of postponed job register
pre-registration

All kind of AST nodes use same struct RNode, which has u1, u2, u3 union members
for holding different kind of data.
This has two problems.
1. Low flexibility of data structure
Some nodes, for example NODE_TRUE, don’t use u1, u2, u3. On the other hand,
NODE_OP_ASGN2 needs more than three union members. However they use same
structure definition, need to allocate three union members for NODE_TRUE and
need to separate NODE_OP_ASGN2 into another node.
This change removes the restriction so make it possible to
change data structure by each node type.
2. No compile time check for union member access
It’s developer’s responsibility for using correct member for each node type when it’s union.
This change clarifies which node has which type of fields and enables compile time check.
This commit also changes node_buffer_elem_struct buf management to handle
different size data with alignment.

In `rb_ruby_ripper_parser_allocate`, `r->p` is NULL between creating
`self` and `parser_params` assignment. As GC can happen there, the
typed-data functions for it need to consider the case.

Introduce Universal Parser mode for the parser.
This commit includes these changes:
* Introduce `UNIVERSAL_PARSER` macro. All of CRuby related functions
are passed via `struct rb_parser_config_struct` when this macro is enabled.
* Add CI task with 'cppflags=-DUNIVERSAL_PARSER' for ubuntu.

The socket extensions rubysocket.h pulls in the "private" include/gc.h,
which now depends on vm_core.h. vm_core.h pulls in id.h
when tool/update-deps generates the dependencies for the makefiles, it
generates the line for id.h to be based on VPATH, which is configured in
the extconf.rb for each of the extensions. By default VPATH does not
include the actual source directory of the current Ruby so the
dependency fails to resolve and linking fails.
We need to append the topdir and top_srcdir to VPATH to have the
dependancy picked up correctly (and I believe we need both of these to
cope with in-tree and out-of-tree builds).
I copied this from the approach taken in
https://github.com/ruby/ruby/blob/master/ext/objspace/extconf.rb#L3

Implementation for Language Server Protocol (LSP) sometimes needs token information.
For example both `m(1)` and `m(1, )` has same AST structure other than node locations
then it's impossible to check the existence of `,` from AST. However in later case,
it might be better to suggest variables list for the second argument.
Token information is important for such case.
This commit adds these methods.
* Add `keep_tokens` option for `RubyVM::AbstractSyntaxTree.parse`, `.parse_file` and `.of`
* Add `RubyVM::AbstractSyntaxTree::Node#tokens` which returns tokens for the node including tokens for descendants nodes.
* Add `RubyVM::AbstractSyntaxTree::Node#all_tokens` which returns all tokens for the input script regardless the receiver node.

This commit adds a `capacity` field to shapes, and adds shape
transitions whenever an object's capacity changes. Objects which are
allocated out of a bigger size pool will also make a transition from the
root shape to the shape with the correct capacity for their size pool
when they are allocated.
This commit will allow us to remove numiv from objects completely, and
will also mean we can guarantee that if two objects share shapes, their
IVs are in the same positions (an embedded and extended object cannot
share shapes). This will enable us to implement ivar sets in YJIT using
object shapes.

`"<*>"` is supported by Bison 2.3b (2008-05-27) or later.
https://git.savannah.gnu.org/cgit/bison.git/commit/?id=12e3584054c16ab255672c07af0ffc7bb220e8bc
Therefore developers need to install Bison 2.3b+ to build ruby from
source codes if their Bison is older.
Minimum version requirement for Bison is changed to 3.0.

Fixes id.h error during updating ripper.c by `make after-update`.
While it used to update id.h in the build directory, but was trying to
update ripper.c in the source directory. In principle, files in the
source directory can or should not depend on files in the build
directory.

The old code of IRB still uses this method. The warning is noisy on
rails console.
In principle, Ruby 3.1 deprecates nothing, so let's avoid the
deprecation for the while.
I think It is not so hard to continue to maintain it as it is a trivial
shim.

Alias `#inspect` as `#to_s` also in the new `Ripper::Lexer::Elem`
class, so that `puts Ripper::Lexer.new(code).scan` shows the
attributes.
|
|
Discussed in https://github.com/ruby/ruby/pull/5093#issuecomment-964426481.
> it would be enough to mimic only [] for almost all cases
This adds back the `Lexer::Elem#[]` and `Lexer::State#[]` and adds deprecation warnings for them.
|
|
The last element in the `@buf` may be either an array or an `Elem`. In the case it is an `Elem` we iterate over every element, when we do not need to. This check guards that case by ensuring that we only iterate over an array of elements.

## Concept
I am proposing we replace the Struct implementation of data structures inside of ripper with real classes.
This will improve performance and the implementation is not meaningfully more complicated.
## Example
Struct versus class comparison:
```ruby
Elem = Struct.new(:pos, :event, :tok, :state, :message) do
def initialize(pos, event, tok, state, message = nil)
super(pos, event, tok, State.new(state), message)
end
# ...
def to_a
a = super
a.pop unless a.empty?
a
end
end
class ElemClass
attr_accessor :pos, :event, :tok, :state, :message
def initialize(pos, event, tok, state, message = nil)
@pos = pos
@event = event
@tok = tok
@state = State.new(state)
@message = message
end
def to_a
if @message
[@pos, @event, @tok, @state, @message]
else
[@pos, @event, @tok, @state]
end
end
end
# stub state class creation for now
class State; def initialize(val); end; end
```
## MicroBenchmark creation
```ruby
require 'benchmark/ips'
require 'ripper'
pos = [1, 2]
event = :on_nl
tok = "\n".freeze
state = Ripper::EXPR_BEG
Benchmark.ips do |x|
x.report("struct") { Elem.new(pos, event, tok, state) }
x.report("class ") { ElemClass.new(pos, event, tok, state) }
x.compare!
end; nil
```
Gives ~1.2x faster creation:
```
Warming up --------------------------------------
struct 263.983k i/100ms
class 303.367k i/100ms
Calculating -------------------------------------
struct 2.638M (± 5.9%) i/s - 13.199M in 5.023460s
class 3.171M (± 4.6%) i/s - 16.078M in 5.082369s
Comparison:
class : 3170690.2 i/s
struct: 2638493.5 i/s - 1.20x (± 0.00) slower
```
## MicroBenchmark `to_a` (Called by Ripper.lex for every element)
```ruby
require 'benchmark/ips'
require 'ripper'
pos = [1, 2]
event = :on_nl
tok = "\n".freeze
state = Ripper::EXPR_BEG
struct = Elem.new(pos, event, tok, state)
from_class = ElemClass.new(pos, event, tok, state)
Benchmark.ips do |x|
x.report("struct") { struct.to_a }
x.report("class ") { from_class.to_a }
x.compare!
end; nil
```
Gives 1.46x faster `to_a`:
```
Warming up --------------------------------------
struct 612.094k i/100ms
class 893.233k i/100ms
Calculating -------------------------------------
struct 6.121M (± 5.4%) i/s - 30.605M in 5.015851s
class 8.931M (± 7.9%) i/s - 44.662M in 5.039733s
Comparison:
class : 8930619.0 i/s
struct: 6121358.9 i/s - 1.46x (± 0.00) slower
```
## MicroBenchmark data access
```ruby
require 'benchmark/ips'
require 'ripper'
pos = [1, 2]
event = :on_nl
tok = "\n".freeze
state = Ripper::EXPR_BEG
struct = Elem.new(pos, event, tok, state)
from_class = ElemClass.new(pos, event, tok, state)
Benchmark.ips do |x|
x.report("struct") { struct.pos[1] }
x.report("class ") { from_class.pos[1] }
x.compare!
end; nil
```
Gives ~1.17x faster data access:
```
Warming up --------------------------------------
struct 1.694M i/100ms
class 1.868M i/100ms
Calculating -------------------------------------
struct 16.149M (± 6.8%) i/s - 81.318M in 5.060633s
class 18.886M (± 2.9%) i/s - 95.262M in 5.048359s
Comparison:
class : 18885669.6 i/s
struct: 16149255.8 i/s - 1.17x (± 0.00) slower
```
## Full benchmark integration of this inside of Ripper.lex
Inside of this repo with this commit
```
$ cd ext/ripper
$ make
$ cat test.rb
file = File.join(__dir__, "../../array.rb")
source = File.read(file)
bench = Benchmark.measure do
10_000.times.each do
Ripper.lex(source)
end
end
puts bench
```
Then execute with and without this change 50 times:
```
rm new.txt
rm old.txt
for i in {0..50}
do
`ruby -Ilib -rripper -rbenchmark ./test.rb >> new.txt`
`ruby -rripper -rbenchmark ./test.rb >> old.txt`
done
```
I used derailed benchmarks internals to compare the results:
```
dir = Pathname(".")
branch_info = {}
branch_info["old"] = { desc: "Struct lex", time: Time.now, file: dir.join("old.txt"), name: "old" }
branch_info["new"] = { desc: "Class lex", time: Time.now, file: dir.join("new.txt"), name: "new" }
stats = DerailedBenchmarks::StatsFromDir.new(branch_info)
stats.call.banner
```
Which gave us:
```
