* NEWS.md: Add memory view entryKenta Murata2020-09-251-0/+11
| | | | | | | | | The memory view interface added at 890bc2cdde is experimental new C-API set. This feature permits extension libraries to share a memory area that contains such a numerical array and a bitmap image. This is designed by referring to Python's buffer protocol. [[Feature #13767]] [[Feature #14722]]

* Support passing a category to `Warning.warn`eileencodes2020-09-011-0/+8
| | | | | | | | | | | | | | | | | | | | | | This change adds a `category` kwarg to make it easier to monkey patch `Warning.warn`. Warnings already have a category, but that warning isn't exposed. This implements a way to get the category so that warnings with a specific category, like deprecated, can be treated differently than other warnings in an application. The change here does an arity check on the method to support backwards compatibility for applications that may already have a warning monkey patch. For our usecase we want to `raise` for deprecation warnings in order to get the behavior for the next Ruby version. For example, now that we fixed all our warnings and deployed Ruby 2.7 to production, we want to be able to have deprecation warnings behave like they would in 3.0: raise an error. For other warnings, like uninialized constants, that behavior won't be removed from Ruby in the next version, so we don't need to raise errors.

This reverts commit 9b8825b6f94696c9659f93f5da9bf02644625f67. I found that combining sweep and move is not safe. I don't think that we can do compaction concurrently with _anything_ unless there is a read barrier installed. Here is a simple example. A class object is freed, and during it's free step, it tries to remove itself from its parent's subclass list. However, during the sweep step, the parent class was moved and the "currently being freed" class didn't have references updated yet. So we get a segv like this: ``` (lldb) bt * thread #1, name = 'ruby', stop reason = signal SIGSEGV * frame #0: 0x0000560763e344cb ruby`rb_st_lookup at st.c:320:43 frame #1: 0x0000560763e344cb ruby`rb_st_lookup(tab=0x2f7469672f6e6f72, key=3809, value=0x0000560765bf2270) at st.c:1010 frame #2: 0x0000560763e8f16a ruby`rb_search_class_path at variable.c:99:9 frame #3: 0x0000560763e8f141 ruby`rb_search_class_path at variable.c:145 frame #4: 0x0000560763e8f141 ruby`rb_search_class_path(klass=94589785585880) at variable.c:191 frame #5: 0x0000560763ec744e ruby`rb_vm_bugreport at vm_dump.c:996:17 frame #6: 0x0000560763f5b958 ruby`rb_bug_for_fatal_signal at error.c:675:5 frame #7: 0x0000560763e27dad ruby`sigsegv(sig=<unavailable>, info=<unavailable>, ctx=<unavailable>) at signal.c:955:5 frame #8: 0x00007f8b891d33c0 libpthread.so.0`___lldb_unnamed_symbol1$$libpthread.so.0 + 1 frame #9: 0x0000560763efa8bb ruby`rb_class_remove_from_super_subclasses(klass=94589790314280) at class.c:93:56 frame #10: 0x0000560763d10cb7 ruby`gc_sweep_step at gc.c:2674:2 frame #11: 0x0000560763d1187b ruby`gc_sweep at gc.c:4540:2 frame #12: 0x0000560763d101f0 ruby`gc_start at gc.c:6797:6 frame #13: 0x0000560763d15153 ruby`rb_gc_compact at gc.c:7479:12 frame #14: 0x0000560763eb4eb8 ruby`vm_exec_core at vm_insnhelper.c:5183:13 frame #15: 0x0000560763ea9bae ruby`rb_vm_exec at vm.c:1953:22 frame #16: 0x0000560763eac08d ruby`rb_yield at vm.c:1132:9 frame #17: 0x0000560763edb4f2 ruby`rb_ary_collect at array.c:3186:9 frame #18: 0x0000560763e9ee15 ruby`vm_call_cfunc_with_frame at vm_insnhelper.c:2575:12 frame #19: 0x0000560763eb2e66 ruby`vm_exec_core at vm_insnhelper.c:4177:11 frame #20: 0x0000560763ea9bae ruby`rb_vm_exec at vm.c:1953:22 frame #21: 0x0000560763eac08d ruby`rb_yield at vm.c:1132:9 frame #22: 0x0000560763edb4f2 ruby`rb_ary_collect at array.c:3186:9 frame #23: 0x0000560763e9ee15 ruby`vm_call_cfunc_with_frame at vm_insnhelper.c:2575:12 frame #24: 0x0000560763eb2e66 ruby`vm_exec_core at vm_insnhelper.c:4177:11 frame #25: 0x0000560763ea9bae ruby`rb_vm_exec at vm.c:1953:22 frame #26: 0x0000560763ceee01 ruby`rb_ec_exec_node(ec=0x0000560765afa530, n=0x0000560765b088e0) at eval.c:296:2 frame #27: 0x0000560763cf3b7b ruby`ruby_run_node(n=0x0000560765b088e0) at eval.c:354:12 frame #28: 0x0000560763cee4a3 ruby`main(argc=<unavailable>, argv=<unavailable>) at main.c:50:9 frame #29: 0x00007f8b88e560b3 libc.so.6`__libc_start_main + 243 frame #30: 0x0000560763cee4ee ruby`_start + 46 (lldb) f 9 frame #9: 0x0000560763efa8bb ruby`rb_class_remove_from_super_subclasses(klass=94589790314280) at class.c:93:56 90 91 *RCLASS_EXT(klass)->parent_subclasses = entry->next; 92 if (entry->next) { -> 93 RCLASS_EXT(entry->next->klass)->parent_subclasses = RCLASS_EXT(klass)->parent_subclasses; 94 } 95 xfree(entry); 96 } (lldb) command script import -r misc/lldb_cruby.py lldb scripts for ruby has been installed.

* Reduce allocations for keyword argument hashesJeremy Evans2020-03-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, passing a keyword splat to a method always allocated a hash on the caller side, and accepting arbitrary keywords in a method allocated a separate hash on the callee side. Passing explicit keywords to a method that accepted a keyword splat did not allocate a hash on the caller side, but resulted in two hashes allocated on the callee side. This commit makes passing a single keyword splat to a method not allocate a hash on the caller side. Passing multiple keyword splats or a mix of explicit keywords and a keyword splat still generates a hash on the caller side. On the callee side, if arbitrary keywords are not accepted, it does not allocate a hash. If arbitrary keywords are accepted, it will allocate a hash, but this commit uses a callinfo flag to indicate whether the caller already allocated a hash, and if so, the callee can use the passed hash without duplicating it. So this commit should make it so that a maximum of a single hash is allocated during method calls. To set the callinfo flag appropriately, method call argument compilation checks if only a single keyword splat is given. If only one keyword splat is given, the VM_CALL_KW_SPLAT_MUT callinfo flag is not set, since in that case the keyword splat is passed directly and not mutable. If more than one splat is used, a new hash needs to be generated on the caller side, and in that case the callinfo flag is set, indicating the keyword splat is mutable by the callee. In compile_hash, used for both hash and keyword argument compilation, if compiling keyword arguments and only a single keyword splat is used, pass the argument directly. On the caller side, in vm_args.c, the callinfo flag needs to be recognized and handled. Because the keyword splat argument may not be a hash, it needs to be converted to a hash first if not. Then, unless the callinfo flag is set, the hash needs to be duplicated. The temporary copy of the callinfo flag, kw_flag, is updated if a hash was duplicated, to prevent the need to duplicate it again. If we are converting to a hash or duplicating a hash, we need to update the argument array, which can including duplicating the positional splat array if one was passed. CALLER_SETUP_ARG and a couple other places needs to be modified to handle similar issues for other types of calls. This includes fairly comprehensive tests for different ways keywords are handled internally, checking that you get equal results but that keyword splats on the caller side result in distinct objects for keyword rest parameters. Included are benchmarks for keyword argument calls. Brief results when compiled without optimization: def kw(a: 1) a end def kws(**kw) kw end h = {a: 1} kw(a: 1) # about same kw(**h) # 2.37x faster kws(a: 1) # 1.30x faster kws(**h) # 2.19x faster kw(a: 1, **h) # 1.03x slower kw(**h, **h) # about same kws(a: 1, **h) # 1.16x faster kws(**h, **h) # 1.14x faster
