In practice the buffer is more than large enough, since all we substitute are process ids, but gcc can't know that.

openldap: check ld structure before passing it to ldap_unbind()

configure.ac: detect compiler vendor
I'll use this in followup patches to detect if the compiler supports
various warning flags. For example, a long standing issue is that older
version of the Sun studio compiler doesn't support -Werror.

curl_json plugin: Refactor the way trees/keys are stored.
Previously, keys had a "magic" as their first member which was used to
differentiate between the two types when they were returned from the
binary search tree.
This patch creates a new struct, cj_tree_entry_t, which includes an enum
identifying which union member is valid.
Florian Forster [Mon, 15 May 2017 12:40:26 +0000 (14:40 +0200)]
curl_json plugin: Fix array index and key handling.
Previously, the "key" was loaded by calling cj_cb_map_key() from
cj_cb_inc_array_index(). That means that the key for the previous element
was loaded as the array index was updated for the next element, resulting
in an off-by-one error. Also the key was not unset in time, resulting in
two metrics with the same identifier being created.
This patch fixes this with the following changes:
* cj_advance_array() (nee cj_cb_inc_array_index()) now loads the key for
the new index position instead of the previous one.
* The initial "0" key is loaded from cj_cb_start_array().
* cj_advance_array() always updates the key. The "update_key" argument
has been removed.
* Refactoring: key loading has been moved out of cj_cb_map_key() and
into its own function, cj_load_key().
Unit tests are in a separate commit for easier cherry-picking.

virt plugin: Replace virTypedParamsFree() with virTypedParamsClear() and sfree().
The parameters are allocated with calloc(), freeing them with a library
function is unintuitive at best. Also, the library functions appears to
be missing the appropriate function attribute to tell clang / GCC that
it will free the pointer, resulting in a false-positive scan-build
report.
