This reverts commit dc51d89ac22acc60b9bfeed87115863565b74085.
|
|
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
|
|
Addressed an issue where existing programs linking `libmruby.a` could only
be built by adding `<build-dir>/include` to compiler's include path.

Fix invalid pointer free inside other heap's block
1. `e = mrb_obj_alloc(...)`
2. `e->stack = mrb->c->stack` (`mrb->c->stack` is anywhere in the range `stbase...stend`)
3. And raised exception by `mrb_malloc()`!
4. `mrb_free(e->stack)` by GC part (wrong free)

Fix memory leak for string object when out of memory
The `mrb_str_pool()` function has a path to call `malloc()` twice.
If occurs `NoMemoryError` exception in second `malloc()`,
first `malloc()` pointer is not freed.

Fix stack overflow when out of memory
As a result of this change, no backtrace information is set
for NoMemoryError (`mrb->nomem_err`).
Detailes:
When generating a backtrace, called `mrb_intern_lit()`,
`mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with
`exc_debug_info()` function in `src/error.c`.
If a `NoMemoryError` exception occurs at this time,
the `exc_debug_info()` function will be called again,
and in the same way `NoMemoryError` exception raised will result
in an infinite loop to occurs stack overflow (and SIGSEGV).

Fix NULL pointer dereference `mrb->nomem_err` when not initialized
Add internal functions (not `static`):
* `mrb_raise_nomemory()`
* `mrb_core_init_abort()`
|
|
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)
```

changes:
* rename DISABLE_STDIO -> MRB_DISABLE_STDIO
* rename ENABLE_DEBUG -> MRB_ENABLE_DEBUG_HOOK
* no more opposite macro definitions (e.g. ENABLE_STDIO, DISABLE_DEBUG).
* rewrite above macro references throughout the code.
* update documents

mrb_inspect() also calls mrb_obj_as_string() after #inspect to ensure
the mrb_value is a string.

C API mrb_p() is always callable.
- But it will do nothing when ENABLE_STDIO is not defined.
Kernel#__printstr__ is always callable.
- But it will do nothing when ENABLE_STDIO is not defined.
