* The previous code is correct, but hard to verify: The libmpdec documentationStefan Krah2012-04-181-1/+2
| | | | | | | | | | | rightfully states that an mpd_t with a coefficient flagged as MPD_CONST_DATA must not be in the position of the result operand. In this particular case several assumptions guarantee that a resize will never occur in all possible code paths, which was the reason for using MPD_CONST_DATA and saving an instruction by omitting the initialization of tmp.alloc. For readability, tmp is now flagged as MPD_STATIC_DATA and tmp.alloc is initialized.

* | 1) Remove claim of an input invariant that is only true for static mpd_t.Stefan Krah2012-04-102-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resizing is used _inside_ libmpdec functions, and it is permitted to change x->alloc several times while setting x->len at the end of the function. Therefore, for dynamic mpd_t x->alloc can _temporarily_ drop below x->len. Of course the final result always has x->len <= x->alloc. For static mpd_t this cannot happen, since resizing to a smaller coefficient is a no-op. 2) Remove micro optimization in mpd_switch_to_dyn(): Previously only the valid initialized part of the existing coefficient up to x->len was copied to the new dynamic memory area. Now copying does the same as realloc() and the entire old memory area is copied. The rationale for this change is that it is no longer needed to memorize the explanation given in 1).

Because it is intended for logging sensitive log messages, it is better that a program trying to log such messages fail than that it log them insecurely. Initial patch by Federico Reghenzani.
