* iseq.c: add a map from encoded insn to insn datamame2018-08-234-35/+54
| | | | | | | | | | This enhances rb_vm_insn_addr2insn which retrieves a decoded insn number from encoded insn. The insn data table include not only decoded insn number, but also its len, trace and non-trace version of encoded insn. This table can be used to simplify trace instrumentation. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64518 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* check trace flags at loading [Bug #14702]ko12018-08-234-4/+28
| | | | | | | | | | | | * iseq.c (iseq_init_trace): at ISeq loading time, we need to check `ruby_vm_event_enabled_flags` to turn on trace instructions. Seprate this checking code from `finish_iseq_build()` and make new function. `iseq_ibf_load()` calls this funcation after loading. * test/ruby/test_iseq.rb: add a test for this fix. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64514 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* parse.y (arg_append): support NODE_ARGSCAT casemame2018-08-221-0/+5
| | | | | | | | | | Because of the lack of this case, `[*ary,1,2,3,4,5,6]` was parsed into an inefficient AST like `ary + [1,2] + [3,4] + [5,6]`. A patch from Anmol Chopra <anmolchopra@rocketbox.in>. Fixes [Bug #15018]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64510 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* compile.c: remove tracecoverage instruction for line coveragemame2018-08-225-26/+19
| | | | | | | 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
* parse.y: remove coverage-related code fragmentsmame2018-08-226-31/+13
| | | | | | | | | | | | | 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

* thread.c (rb_reset_coverages): remove coverage counters from all ISeqsmame2018-08-223-0/+22
| | | | | | | | | | | | | When coverage measurement is enabled, the compiler makes each iseq have a reference to the counter array of coverage. Even after coverage measurement is disabled, the reference is kept. And, if coverage measurement is restarted, a coverage hook will increase the counter. This is completely meaningless; it brings just overhead. To remove this meaninglessness, this change removes all the reference when coverage measuement is stopped. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64504 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* spec/ruby/core/io/select_spec.rb: workaround stuck IO.selectnormal2018-08-201-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under pipe page memory pressure on Linux, a pipe may only be created with a single buffer[1]. And as of Linux v4.18, the fs/pipe.c::pipe_poll callback does not account for merging done in fs/pipe::pipe_write; only the number of usable buffers in the pipe. Thus it is possible for a pipe to be writable (if only by a small amount) despite IO.select saying it is not. With the default 16384 /proc/sys/fs/pipe-user-pages-soft value and the pipe having 16 pages of buffers, this issue is trivially reproducible by creating 1024 pipes in a background process before running the spec: $ ulimit -n 2053 # or something higher $ ./miniruby -e '1024.times.map { IO.pipe }; sleep' & $ make test-spec MSPECOPT=spec/ruby/core/io/select_spec.rb So, we create a new pipe we never write to for testing writability of IO.select. This may cause the test to fail with ENFILE on an overloaded system, but at least that's an obvious failure (unlike having a test get stuck). This should reduce failures on our overloaded CI machines: http://ci.rvm.jp/results/trunk-nopara@silicon-docker/1239426 [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/fs/pipe.c?h=v4.18#n642 git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64478 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | This is needed to reliably fix ConditionVariable#wait on Thread#kill [Bug #14999] because there is still a chance an interrupt could fire and prevent lock acquisition after an ensure statement.
