multiple xlators: strncpy()->sprintf(), reduce strlen()'s

2018-09-07T03:39:50+00:00

xlators/cluster/afr/src/afr-common.c
xlators/cluster/dht/src/dht-common.c

xlators/cluster/stripe/src/stripe-helpers.c

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.

Instead, use snprintf().
Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN (sizeof() ) for const strings.

Compile-tested only!

It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.

In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.

1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.

Only compile-tested!

multiple files: move from strlen() to sizeof()

tools/setgfid2path/src/main.c

{glusterfs-acl|glusterfs}.h

For const strings, just do compile time size calc instead of runtime.

stripe: FORWARD_NULL coverity fix

2018-08-24T05:42:35+00:00

Problem: frame could be NULL.

Solution: Added condition checks to avoid NULL pointer dereferencing.

All: remove memset() before sprintf()

2018-08-14T05:15:04+00:00

It's not needed.
There's a good chance the compiler is smart enough to remove it
anyway, but it can't hurt - I hope.

All: run codespell on the code and fix issues.

2018-07-22T14:40:16+00:00

Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...
