mgmt xlators: store boolean fields using integer

2018-09-11T07:10:48+00:00

Surprisingly, there is not set_boolean() as there is a get_boolean()
In fact, it is stored as an INT dictionary type.

In some occasions it was stored using a string, and this caused
errors such as:
key gfproxy-server, integer type asked, has string type [Invalid argument]

I've fixed what I saw in some logs, I'm sure there are more.
The CORRECT fix is to create a boolean set and use it, but this
requires a bit more work. I'll see if I can do it later on.

Only compile-tested!

glusterd: NULL pointer dereferencing clang fix

2018-09-11T05:57:54+00:00

problem: NULL point dereferencing

solution: Adding a conditional statement before and then dereferencing it.

Some (mgmt) xlators: use dict_{setn|getn|deln|get_int32n|set_int32n|set_strn}

2018-09-09T01:53:59+00:00

In a previous patch (https://review.gluster.org/20769) we've
added the key length to be passed to dict_* funcs, to remove the need
to strlen() it. This patch moves some xlators to use it.

- It also adds dict_get_int32n which was missing.
- It also reduces the size of some key variables.
They were set to 1024b or PATH_MAX, where sometimes 64 bytes were
really enough.

Please review carefully:
1. That I did not reduce some the size of the key variables too much.
2. That I did not mix up some keys.

Compile-tested only!

Move to GF_MALLOC() instead of GF_CALLOC() when possible

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!

.. and allocate memory as much as needed.

xlators/nfs/server/src/mount3.c :

Don't blindly allocate PATH_MAX, but strlen() the string and allocate
appropriately.
Also, align error messges.

mgmt/glusterd: Fix memory leaks in glusterd-op-sm.c

2018-08-23T03:44:18+00:00

Addresses the following CIDs:

- 1124704: Removed an unessential variable that caused a memory
leak in glusterd_op_set_volume(). Nuked an unnecessary log message upon
error as well since failure logging is being done in the caller

- 1124772: Memory leak in an error path of
glusterd_op_ac_send_brick_op()

- 1175021: Removed an unessential variable that caused a memory leak in
glusterd_op_build_payload()

Also addressed a memory leak in an error path of
glusterd_dict_set_volid()

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.
