Since no one objected to my suggestion here:
http://thread.gmane.org/gmane.comp.emulators.libvirt/3956/focus=4039
> Given code like T *var = calloc (n, sizeof (T));
> I prefer this: T *var = calloc (n, sizeof (*var));
I've gone ahead with some first steps.
With the patch below, there are only two .o files with differences.
Mainly for my own reference, here's what I did:
make CFLAGS=-g
mkdir ../obj
for i in $(find . -name '*.o'); do cp -l --parents $i ../obj;done
make clean
patch -p1 < this-patch
make CFLAGS=-g
for i in $(find . -name '*.o'); do cmp $i ../obj/$i;done
The first difference was due to my minor factorization in xmlrpc.c.
That was expected. However, the second was not. The calloc stmt
below (from remote_internal.c) applies sizeof to the wrong type:
static int remoteAuthMakeCredentials(sasl_interact_t *interact,
virConnectCredentialPtr *cred)
{
int ninteract;
if (!cred)
return -1;
for (ninteract = 0 ; interact[ninteract].id != 0 ; ninteract++)
; /* empty */
*cred = calloc(ninteract, sizeof(virConnectCredential));
if (!*cred)
------------------------
We're lucky virConnectCredential is not smaller than sizeof void*.
If it had been, this would have been a real bug, rather than just an
over-allocation.
I've also removed all casts of malloc, realloc, calloc return values
on the touched lines, since they are universally unnecessary.
-----------------------
Subject: [PATCH] Use a variable name as sizeof argument, not a type name.
Given code like: T *var = calloc (n, sizeof (T));
Convert to this: T *var = calloc (n, sizeof (*var));
This first-cut change adjusts all malloc, calloc, and
realloc statements.
The only binary differences are in remote_internal.c
(due to the bug fix) and in xmlrpc.c (due to factorization).
