libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

Various files: strncpy()->sprintf(), reduce strlen()'s

2018-08-31T13:13:43+00:00

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(). Check for truncated output
where applicable.

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

Compile-tested only!

libglusterfs: Coverity Issue NEGATIVE_RETURNS

2017-09-29T12:37:26+00:00

Issue: Event negative_return_fn: Function "dup(handle->fd)" returns a
negative number. Event negative_returns: "dup(handle->fd)" is passed
to a parameter that cannot be negative.

With this change value of dup(handle->fd) is stored in duped_fd & if
condition checks the value of duped_fd is non-negative.

glusterd: Gluster should keep PID file in correct location

2017-08-11T07:36:41+00:00

Currently Gluster keeps process pid information of all the daemons
and brick processes in Gluster configuration file directory
(ie., /var/lib/glusterd/*).

These pid files should be seperate from configuration files.
Deletion of the configuration file directory might result into serious problems.
Also, /var/run/gluster is the default placeholder directory for pid files.

So, with this fix Gluster will keep all process pid information of all
processes in /var/run/gluster/* directory.

core: use syscall wrappers instead of direct syscalls - libglusterfs

2015-11-16T14:18:10+00:00

various xlators and other components are invoking system calls
directly instead of using the libglusterfs/syscall.[ch] wrappers.

If not using the system call wrappers there should be a comment
in the source explaining why the wrapper isn't used.

libglusterfs: pass buffer size to gf_store_read_and_tokenize function

2015-10-14T20:42:30+00:00

Previously if user set an option where length of key=value goes beyond
PATH_MAX (4096) character then tokenzing the option at the time of
reading configuration file will fail.
This is because of the we was having restraction in fgets to read maximum
of PATH_MAX (4096) length of character.
Consequence of this is when user try to restart glusterd, after setting
key=value length beyond PATH_MAX (4096) character, glusterd will not restart.

With this fix instead of PATH_MAX, consumer of gf_store_read_and_tokenize
function will decide the size of the buffer length.
