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).

2019-08-05Use 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.

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.

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.
