2020-01-31Avoid implicit integer casting in `backtrace.c` and `hash.c`.Yukihiro "Matz" Matsumoto
2019-12-18Simplify `print_backtrace()`KOBAYASHI Shuji
2019-12-17Refine output of `mrb_print_error()`KOBAYASHI Shuji
The following improvements are made according to Ruby's behavior: - Match location number to index. - Remove duplicate most recent call output. - Fix that first call is not output when array (unpacked) backtrace. ### Example ```ruby def a; raise "error!" end def b; a end begin b rescue => e e.backtrace if ARGV[0] == "unpack" # unpack backtrace raise e end ``` #### Before this patch: ``` $ bin/mruby example.rb unpack trace (most recent call last): [0] example.rb:2:in b [1] example.rb:1:in a example.rb:1: error! (RuntimeError) ``` #### After this patch: ``` $ bin/mruby example.rb unpack trace (most recent call last): [2] example.rb:4 [1] example.rb:2:in b example.rb:1:in a: error! (RuntimeError) ```
2019-12-16Remove unneeded null checks to `struct backtrace_location::filename`KOBAYASHI Shuji
`struct backtrace_location` is created only in `each_backtrace()`, and the `filename` field will never be null (it will be `(unknown)` if null).
2019-09-25Rename symbol-to-string functions; close #4684Yukihiro "Matz" Matsumoto
* mrb_sym2name -> mrb_sym_name * mrb_sym2name_len -> mrb_sym_name_len * mrb_sym2str -> mrb_sym_str

2019-08-05Use new specifiers/modifiers of `mrb_vfromat()`KOBAYASHI Shuji
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in my environment than before the introduction of new specifiers/modifiers (5116789a) with this change. ------------+-------------------+-------------------+-------- BINARY | BEFORE (5116789a) | AFTER (This PR) | RATIO ------------+-------------------+-------------------+-------- mruby | 593416 bytes | 593208 bytes | -0.04% libmruby.a | 769048 bytes | 767264 bytes | -0.23% ------------+-------------------+-------------------+-------- BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613, so I put it back.
2019-07-15Unify type of line number to `uint16_t`KOBAYASHI Shuji
2019-04-01Avoid keeping pointers from `mrb_sym2name_len()`; fix #4342Yukihiro "Matz" Matsumoto
The addresses for packed inline symbols reference `mrb->symbuf` that could be overridden by the later call of `mrb_sym2name_len`. Since file names in call stack information are kept as symbols, keeping the address in the C structures could cause problems like #4342. This changes small incompatible changes in function prototypes: * `mrb_parser_get_filename`: return value changed to `mrb_sym`. * `mrb_debug_get_filename`: add `mrb_state*` as a first argument. * `mrb_debug_get_line`: ditto. I believe above functions are almost internal, and no third-party mrbgem use them.
2019-03-27Remove unused variable in `each_backtrace()`KOBAYASHI Shuji
2019-02-25Refactor `src/backtrace.c`KOBAYASHI Shuji
- Move calling `mrb_debug_get_filename()` to after `lineno` check. - Remove unneeded array check in `print_backtrace()`. - Add a few `const` qualifier.

2017-05-23Simplify backtrace mechanism; fix #3633 #3634 #3644Yukihiro "Matz" Matsumoto
Instead of preserving a backtrace in `mrb_state`, `mrb_exc_set` keeps packed backtrace in an exception object. `#backtrace` unpacks it to an array of strings.

2016-02-26The original code crashed when mrb->backtrace.n grew to 16.Carlo Prelz
It looks like the logic to reallocate the backtrace was flawed, based on the wrong variable (loc_raw->i, which, as I have verified, decreases from 16 to 0 instead of increasing) I am not sure if this is the correct fix
2016-01-07Fix segfault on mrb_exc_backtrace.Simon Génier
The code to iterate over backtrace locations was changed in #3065, but unfortunately output_backtrace was not correctly updated to forward the callback.
