[PATCH] date_core: RB_GC_GUARD temporary strings
ext/date/date_core.c (d_lite_inspect): RB_GC_GUARD temporary strings
test/date/test_date.rb: add test case with GC.stress=true
RSTRING_PTR() should not be used directly on function calls:
1) it may drop the VALUE reference from the stack/register set
and and allow GC to collect it
2) macros can evaluate the function call multiple times
If DNDEBUG is not defined, Date#inspect_raw also has the same issue.
However, I think removing the Date#inspect_raw code entirely is better.
If you prefer to use "git pull":
git pull git://bogomips.org/ruby date_core-gc-guard
#1 [ruby-core:38865] Updated by Eric Wong over 5 years ago
I also have an extra safety fix in case date_strftime_with_tmx() changes
in the future:
ext/date/date_strftime.c (date_strftime_with_tmx): RB_GC_GUARD safety fix
I don't think this has the potential to /currently/ cause errors
because the pointer is used immediately (before further
allocations). However it is still a risk if the code changes
and allocates later in the function.
There should also be a minor speedup from avoiding strlen().
