* btest: assign $stderr = STDOUT instead of IO#reopen to be more portableYuta Saito2021-12-161-2/+2
| | | | | | `IO#reopen` internally uses dup syscall but some platforms don't support the syscall. re-assigning `$stderr` is enough to capture the interpreter's errors and warnings.
* Lazily create singletons on instance_{exec,eval} (#5146)John Hawthorn2021-12-021-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Lazily create singletons on instance_{exec,eval} Previously when instance_exec or instance_eval was called on an object, that object would be given a singleton class so that method definitions inside the block would be added to the object rather than its class. This commit aims to improve performance by delaying the creation of the singleton class unless/until one is needed for method definition. Most of the time instance_eval is used without any method definition. This was implemented by adding a flag to the cref indicating that it represents a singleton of the object rather than a class itself. In this case CREF_CLASS returns the object's existing class, but in cases that we are defining a method (either via definemethod or VM_SPECIAL_OBJECT_CBASE which is used for undef and alias). This also happens to fix what I believe is a bug. Previously instance_eval behaved differently with regards to constant access for true/false/nil than for all other objects. I don't think this was intentional. String::Foo = "foo" "".instance_eval("Foo") # => "foo" Integer::Foo = "foo" 123.instance_eval("Foo") # => "foo" TrueClass::Foo = "foo" true.instance_eval("Foo") # NameError: uninitialized constant Foo This also slightly changes the error message when trying to define a method through instance_eval on an object which can't have a singleton class. Before: $ ruby -e '123.instance_eval { def foo; end }' -e:1:in `block in <main>': no class/module to add method (TypeError) After: $ ./ruby -e '123.instance_eval { def foo; end }' -e:1:in `block in <main>': can't define singleton (TypeError) IMO this error is a small improvement on the original and better matches the (both old and new) message when definging a method using `def self.` $ ruby -e '123.instance_eval{ def self.foo; end }' -e:1:in `block in <main>': can't define singleton (TypeError) Co-authored-by: Matthew Draper <matthew@trebex.net> * Remove "under" argument from yield_under * Move CREF_SINGLETON_SET into vm_cref_new * Simplify vm_get_const_base * Fix leaf VM_SPECIAL_OBJECT_CONST_BASE Co-authored-by: Matthew Draper <matthew@trebex.net>
* Turn class variable warnings into exceptionsJeremy Evans2020-04-101-2/+6
| | | | | | | | | | | | | | | | | | This changes the following warnings: * warning: class variable access from toplevel * warning: class variable @foo of D is overtaken by C into RuntimeErrors. Handle defined?(@@foo) at toplevel by returning nil instead of raising an exception (the previous behavior warned before returning nil when defined? was used). Refactor the specs to avoid the warnings even in older versions. The specs were checking for the warnings, but the purpose of the related specs as evidenced from their description is to test for behavior, not for warnings. Fixes [Bug #14541]

* * iseq.c, vm_eval.c: set th->base_block properly.ko12012-06-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | th->base_block is information for (a) parsing, (b) compiling and (c) setting up the frame to execute the program passed by `eval' method. For example, (1) parser need to know up-level variables to detect it is variable or method without paren. Befor (a), (b) and (c), VM set th->base_block by passed bindng (or previous frame information). After execute (a), (b) and (c), VM should clear th->base_block. However, if (a), (b) or (c) raises an exception, then th->base_block is not cleared. Problem is that the uncleared value th->balo_block is used for irrelevant iseq compilation. It causes SEGV or critical error. I tried to solve this problem: to clear them before exception, but finally I found out that it is difficult to do it (Ruby program can be run in many places). Because of this background, I set th->base_block before compiling iseq and restore it after compiling. Basically, th->base_block is dirty hack (similar to global variable) and this patch is also dirty. * bootstraptest/test_eval.rb: add a test for above. * internal.h: remove unused decl. * iseq.c (rb_iseq_compile_with_option): add base_block parameter. set th->base_block before compation and restore it after compilation. * ruby.c (require_libraries): pass 0 as base_block instead of setting th->base_block * tool/compile_prelude.rb (prelude_eval): apply above changes. * vm.c, vm_eval.c: ditto. * vm_core.h: add comments. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36179 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | | | Divide big array (or hash) literals into several blocks and concatetene them. There was a problem that a big array (hash) literal causes SystemStackError exception (stack overflow) because VM push all contents of the literal onto VM stack to make an array (or hash).
