2016-03-06Fix segmentation fault by backtrace and GCKouhei Sutou
GitHub: fix #3122 It reverts #3126. #3126 fixes the segmentation fault but generates broken backtrace. This change fixes the segmentation fault and generates correct backtrace. The strategy of this change is "generating backtrace while irep is alive". /tmp/test.rb: def gen e0 = nil begin 1.times { raise 'foobar' } rescue => e e0 = e end e0 end e = gen GC.start gen GC.start puts e.backtrace.join("\n") Run: % bin/mruby /tmp/test.rb /tmp/test.rb:5:in Object.gen /home/kou/work/ruby/mruby.kou/mrblib/numeric.rb:77:in Integral#times /tmp/test.rb:4:in Object.gen /tmp/test.rb:13 FYI: % ruby -v /tmp/test.rb ruby 2.3.0p0 (2015-12-25) [x86_64-linux-gnu] /tmp/test.rb:5:in `block in gen' /tmp/test.rb:4:in `times' /tmp/test.rb:4:in `gen' /tmp/test.rb:13:in `<main>'
2015-12-29Support backtrace after method callsKouhei Sutou
GitHub: fix #2902, #2917 The current implementation traverses stack to retrieve backtrace. But stack will be changed when some operations are occurred. It means that backtrace may be broken after some operations. This change (1) saves the minimum information to retrieve backtrace when exception is raised and (2) restores backtrace from the minimum information when backtrace is needed. It reduces overhead for creating backtrace Ruby objects. The space for the minimum information is reused by multiple exceptions. So memory allocation isn't occurred for each exception.

2015-07-16use mrb_str_cat_str() instead of mrb_str_append()cremno
If the argument is always a string, then mrb_str_cat_str() can be directly called instead of indirectly by mrb_str_append(). mrb_any_to_s(), mrb_obj_as_string(), mrb_inspect() always return a string.
2015-07-13refactor mrb_bob_missing to share raising NoMethodError code; fix #2878Yukihiro "Matz" Matsumoto
Note: arguments of mrb_no_method_error() has changed. You need to replace 3rd and 4th argument (say n, argv) to mrb_ary_new_from_values(mrb, n, argv).

mrb_exc_backtrace since this is a backtrace method implementation of Exception; mrb_get_backtrace_at() -> removed; mrb_get_backtrace() -> added to get backtrace in array (like caller)

2014-01-31use mrb_bool, FALSE and TRUE morecremno
It doesn't matter to me if one is using FALSE/TRUE instead of 1/0 but I prefer a type (alias) which emphasizes boolean vars to int. I changed 1/0 to FALSE/TRUE anyway.

remove unused and unneeded: - sysexit_status - type (a global variable) add mrb_ prefix to: - codedump_all - class_instance_method_list - parser_dump make various functions static, incl.: - yyparse - make_exception
2014-01-07remove superfluous includescremno
- reduce compile time by a little bit (full-core: ~0.7s for me) - thanks to 'include-what-you-use' for some help - include Standard C header files before any other (coding style)

2013-11-18renamed mrb_exc_new3 to mrb_exc_new_strcremno
- more descriptive name (there's no mrb_exc_new2) - no wrapper (macro/static inline function) for backwards compatibility because nothing besides mruby itself seems to be calling this function: <http://mruby-code-search.ongaeshi.me/home?query=mrb_exc_new3>
