2023-08-09Fix memory leak for incomplete lambdasPeter Zhu
[Bug #19836] The parser does not free the chain of `struct vtable`, which causes memory leaks. The following script reproduces this issue: ``` 10.times do 100_000.times do Ripper.parse("-> {") end puts `ps -o rss= -p #{$$}` end ``` Notes: Merged: https://github.com/ruby/ruby/pull/8192
2023-08-09Fix memory leak in parser for incomplete tokensPeter Zhu
[Bug #19835] The parser does not free the `tbl` of the `struct vtable` when there are leftover `lvtbl` in the parser. This causes a memory leak. The following script reproduces this issue: ``` 10.times do 100_000.times do Ripper.parse("class Foo") end puts `ps -o rss= -p #{$$}` end ``` Notes: Merged: https://github.com/ruby/ruby/pull/8192

2023-06-30Handle unterminated unicode escapes in regexpsJeremy Evans
This fixes an infinite loop possible after ec3542229b29ec93062e9d90e877ea29d3c19472. For \u{} escapes in regexps, skip validation in the parser, and rely on the regexp code to handle validation. This is necessary so that invalid unicode escapes in comments in extended regexps are allowed.

2023-06-30Don't check for null pointer in calls to freePeter Zhu
According to the C99 specification section 7.20.3.2 paragraph 2: > If ptr is a null pointer, no action occurs. So we do not need to check that the pointer is a null pointer. Notes: Merged: https://github.com/ruby/ruby/pull/8004

2023-06-18Remove coverage_enabled from parser_paramsyui-knk
`yyparse` never changes the value of `coverage_enabled`. `coverage_enabled` depends on only return value of `e_option_supplied`. Therefore `parser_params` doesn't need to have `coverage_enabled. Notes: Merged: https://github.com/ruby/ruby/pull/7951

After 6c0925ba7017efde6091e2ec4f1a6be268166696, it was impossible to distinguish between the presence or absence of `*`. # Before the commit Ripper.sexp('0 in []')[1][0][2][1] #=> [:aryptn, nil, nil, nil, nil] Ripper.sexp('0 in [*]')[1][0][2][1] #=> [:aryptn, nil, nil, [:var_field, nil], nil] # After the commit Ripper.sexp('0 in []')[1][0][2][1] #=> [:aryptn, nil, nil, nil, nil] Ripper.sexp('0 in [*]')[1][0][2][1] #=> [:aryptn, nil, nil, nil, nil] This commit reverts it.
2023-03-31Fix gc_verify_internal_consistency error for pattern_matching in ripperyui-knk
`gc_verify_internal_consistency` reports "found internal inconsistency" for "test_pattern_matching.rb". http://ci.rvm.jp/results/trunk-gc-asserts@ruby-sp2-docker/4501173 Ruby's parser manages objects by two different ways. 1. For parser * markable node holds objects * call `RB_OBJ_WRITTEN` with `p->ast` as parent * `mark_ast_value` marks objects 2. For ripper * unmarkable node, NODE_RIPPER/NODE_CDECL, holds objects * call `rb_ast_add_mark_object`. This function calls `rb_hash_aset` then `RB_OBJ_WRITTEN` is called with `mark_hash` as parent * `mark_hash` marks objects However in current pattern_matching implementation * markable node holds objects * call `rb_ast_add_mark_object` This commit fix it to be #2. This was inconsistency however always `mark_hash` is made young by `rb_ast_add_mark_object` call then objects are not collected. Notes: Merged: https://github.com/ruby/ruby/pull/7627
