----------------------------------
Summary: Macros to wrap malloc(), realloc(), free()
Key: PROTON-726
URL: https://issues.apache.org/jira/browse/PROTON-726
Project: Qpid Proton
Issue Type: Wish
Components: proton-c
Affects Versions: 0.8
Reporter: Adam Nemcek
Priority: Trivial
As we are porting ProtonC across various platforms, we take the trunk code and
use it in a specific project. I would like to be able to take any newer version
from SVN and use it, without the need to modify it each every time, to suit the
target system specifics.
Therefore, I would like to kindly ask for an official support of macros to
replace the memory allocation functions.
Create a single global header file (or reuse some existing one, like the
platform.h), and add a three new macros to it.
Having macros in place of general malloc(), realloc() and free() calls, will
allow to keep the ported version easily update-able when new ProtonC version
comes out (there won't be no need to manually go through all the files and
replacing the calls with other calls).
For Linux (or Windows), the macros will directly link to the default functions.
For other OS(es), the developer will be able to just rewrite three lines of
code and be all set.
Example:
{{pn_buffer_t *buf = (pn_buffer_t *)malloc(sizeof(pn_buffer_t));}}
will get replaced with something like this
{{pn_buffer_t *buf = (pn_buffer_t *)MALLOC_MACRO(sizeof(pn_buffer_t));}}
where (for Linux) it will be:
{{#define MALLOC_MACRO malloc}}
or for other OS it might then be:
{{#define MALLOC_MACRO customMalloc}}
Of course, I do not care about the naming of the macros, or the actual code
style.
I will leave all this on the official developers, I just ask to get such a
functionality in.
This change should have no impact on functionality, code size or speed.
