Yukihiro "Matz" Matsumoto e969229b77 Check backtrace info may not be set (esp. NoMemError); fix #3663 2017-05-25 12:56:19 +09:00
Yukihiro "Matz" Matsumoto 9644ad51b4 Simplify backtrace mechanism; fix #3633 #3634 #3644
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.

Kouhei Sutou d77c72dac5 Revert "Merge pull request #3126 from jbreeden/backtrace_irep_null_check"
This reverts commit bf7719fe8d, reversing
changes made to 4f4fa0ade0.

We should get backtrace while irep is alive.

Carlo Prelz d6cbe1bfc6 The original code crashed when mrb->backtrace.n grew to 16.
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

Simon Génier 146a9eeb38 Fix segfault on mrb_exc_backtrace.
The code to iterate over backtrace locations was changed in #3065, but
unfortunately output_backtrace was not correctly updated to forward the
callback.

Kouhei Sutou a561bdb25f Support backtrace after method calls
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.

 * no more opposite macro definitions (e.g. ENABLE_STDIO, DISABLE_DEBUG).
 * rewrite above macro references throughout the code.
 * update documents
