2023-10-16Fix method coverage comparisonsNobuyoshi Nakada
Although Ruby's hashes preserve the insertion order, the ordering of method coverage results is inherently nondeterministic, because they are collected using `ObjectSpace`.
2023-09-04Revert "Don't reset line coverage for evaled code. (#8330)"Yusuke Endoh
This reverts commit 7e0f5df2f99693267d61636d23da47f79924e9d5. https://bugs.ruby-lang.org/issues/19857#note-7

This adds oneshot_lines as a mode of coverage that is supported. Notes: Merged-By: ioquatix <samuel@codeotaku.com>
2022-11-08Fix false LocalJumpError when branch coverage is enabledYusuke Endoh
`throw TAG_BREAK` instruction makes a jump only if the continuation of catch of TAG_BREAK exactly matches the instruction immediately following the "send" instruction that is currently being executed. Otherwise, it seems to determine break from proc-closure. Branch coverage may insert some recording instructions after "send" instruction, which broke the conditions for TAG_BREAK to work properly. This change forces to set the continuation of catch of TAG_BREAK immediately after "send" (or "invokesuper") instruction. [Bug #18991] Notes: Merged: https://github.com/ruby/ruby/pull/6688

2022-07-11Fix a regression of b2e58b02aec73f9c350bf109c021c180fc699cccYusuke Endoh
At that commit, I fixed a wrong conditional expression that was always true. However, that seemed to have caused a regression. [Bug #18906] This change removes the condition to make the code always enabled. It had been enabled until that commit, albeit unintentionally, and even if it is enabled it only consumes a tiny bit of memory, so I believe it is harmless.

2021-06-23Check type of instruction - can be INSN or ADJUSTeileencodes
If the type is ADJUST we don't want to treat it like an INSN so we have to check the type before reading from `insn_info.events`. [Bug #18001] [ruby-core:104371] Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org> Notes: Merged: https://github.com/ruby/ruby/pull/4601

2019-12-04compile.c: stop wrong peephole optimization when covearge is enabledYusuke Endoh
jump-jump optimization ignores the event flags of the jump instruction being skipped, which leads to overlook of line events. This changeset stops the wrong optimization when coverage measurement is neabled and when the jump instruction has any event flag. Note that this issue is not only for coverage but also for TracePoint, and this change does not fix TracePoint. However, fixing it fundamentally is tough (which requires revamp of the compiler). This issue is critical in terms of coverage measurement, but minor for TracePoint (ko1 said), so we here choose a stopgap measurement. [Bug #15980] [Bug #16397] Note for backporters: this changeset can be viewed by `git diff -w`.

2019-02-01Revert r63383, r63248 "compile.c: copy a short insn with leave"nobu
When copying `leave` insn, TRACE also should be copied if it is present, but this optimization is trivial and not worth the complexity. [ruby-core:91366] [Bug #15578] 4cae5353c03009beb1e0a1619422072773580609 5afd479de63b6609ddcd1510da94d2c1ac384f7f git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66977 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2019-01-01compile.c (iseq_set_sequence): fix branch coverage tablemame
Not only TRACE_ELEMENT but also INSN_ELEMENT may have events. The old pc2branchindex was created using only events of TRACE_ELEMENTs. This change uses events of INSN_ELEMENTs too for pc2branchindex table. [Bug #15476] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66676 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-12-20ext/coverage/lib/coverage.rb (Coverage.line_stub): use only line eventsmame
It wrongly used all linenos of ISeq#trace_points which includes not only line events but also call, return, and other events. So, the result included some linenos that can not be covered at all by line coverage. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66468 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-10-20ext/coverage/: add the oneshot modemame
This patch introduces "oneshot_lines" mode for `Coverage.start`, which checks "whether each line was executed at least once or not", instead of "how many times each line was executed". A hook for each line is fired at most once, and after it is fired, the hook flag was removed; it runs with zero overhead. See [Feature #15022] in detail. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65195 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-22compile.c: remove tracecoverage instruction for line coveragemame
Line coverage was based on special instruction "tracecoverage". Now, instead, it uses the mechanism of trace hook [Feature #14104]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64509 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-22parse.y: remove coverage-related code fragmentsmame
The code fragments that initializes coverage data were scattered into both parse.y and compile.c. parse.y allocated a coverage data, and compile.c initialize the data. To remove this cross-cutting concern, this change moves the allocation from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c. For the sake, parse.y just counts the line number of the original source code, and the number is passed via rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64508 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-12-18iseq.c (finish_iseq_build): fix coverage leakage [Bug #14191]mame
Before this change, coverage.so had failed to measure some multiple-line code fragments. This is because removing trace instructions (#14104) changed TracePoint's lineno (new lineno), and coverage counter array was based on old lineno. This change initializes coverage counter array based on new lineno. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61313 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-12-05ext/coverage/coverage.c: method coverage has column info. of method def.mame
This change makes method coverage result have not only first lineno of method defintion, but also code range (i.e. first lineno, first column, last lineno, and last column). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61026 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-12-05Revamp method coverage to support define_methodmame
Traditionally, method coverage measurement was implemented by inserting `trace2` instruction to the head of method iseq. So, it just measured methods defined by `def` keyword. This commit drastically changes the measuring mechanism of method coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t* to runs (i.e., it counts the runs per method entry), and at `Coverage.result`, it creates the result hash by enumerating all `rb_method_entry_t*` objects (by `ObjectSpace.each_object`). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61023 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
