PHP RFC: Better type names for int64 RFC

- Status: Under Discussion
The int64 RFC introduced a number renames for common types, macros and zpp specifiers, which are both unnecessary and confusing. This RFC proposes to revert the bulk of these renames and use a naming scheme that is consistent with our original types and the terminology used by the C community at large.
The most significant naming changes introduced by the int64 RFC are:
zend_uint_tare the new 64bit-on-64bit-platforms types.
IS_LONGis changed to
Z_STRLENis changed to
These changes are disapproved of for the following reasons:
- These naming changes serve no purpose and will only create additional headaches when porting code to phpng or merging between branches.
- There now exists a
zend_int_ttype (which is a 64bit-on-64bit type) and
zend_int(which is a 32bit type). Apart from the
_tsuffix the name is the same, but the meaning is totally different.
- PHP and the Zend Engine do not use
_tsuffixes for types. This introduces a new type naming convention that is not used anywhere else. (Probably this is done to avoid clashing with the previous point.)
- Furthermore all types ending in
_tare reserved by the POSIX standard.
- Using the term
intfor an 64bit type goes against the normal expectations of a C programmer (ILP64 systems are rare). The meaning of the
zend_int_ttype is much closer to the
Instead the following alternative naming is proposed:
zend_uintas 32bit types (same as 64bit RFC)
zend_ulongas the 64bit-on-64bit-platforms type. As such this type stays the same as previously, with the tweak that it will be 64bit on LLP64 platforms as well.
- Revert all type/macro/zpp renames, like
I, etc. The original names will be used instead.
As this is just search&replace renaming a patch will be provided once we have reached a descision on naming.
