This commit updates `VerifyOrQuit()` and `SuccessOrQuit()` macros to
include the failed condition in the error message that is printed on
a failure (in addition to function name and line number where the
error happened). This commit also changes the second parameter
(`aMessage`) to in these macros to be optional.
This commit also updates unit tests to remove the second `aMessage`
string in cases where the failure can be inferred from the condition
itself.
This commit adds a new core header files `common/error.hpp` which
defines `ot::Error` (mirroring `otError`) and `kError{Name}` constants
(mirroring the public `OT_ERROR_{NAME}` definitions). The new (C++
style) definitions are used by core modules. This commit also moves
`otThreadErrorToString()` (from `logging.hpp` to `error.hpp`) and
renames it to `ErrorToString()` which is used as the internal (to
core) function to covert an `Error` to a string.
This commit adds new methods in `LinkedList` to search in the list for
an entry matching a given entry indicator (specified with a template
`Indicator` type). To use these methods, users are expected to provide
method `bool Matches(const Indicator &aIndicator) const` on the entry
`Type` itself (which is then used to match each entry in the list with
the indicator). This commit also changes the linked-list methods to
use `Find()` internally. Finally it updates the linked-list unit test
to cover behavior of the newly added methods.
This commit fixes the `LinkedList::Find()` implementation when list is
empty. It also updates the unit test for linked-list to verify the
`Find()` (particularly when it is expected to fail and not find the
entry in the list).
This commit changes `LinkedList::PopAfter()` method to accept a
pointer to a previous entry as a parameter. If the previous entry
pointer is NULL the entry at the head of the list is popped.
The `LinkedList::Find()` method searches for a given entry in the
linked list and if found returns a pointer to the previous entry
behind it. The `LinkedList::GetTail()` returns the tail of the list
(last entry in the list). This commit also updates the unit test
`test_linked_list` to verify the behavior of newly added methods.
This commit adds a linked list module which provides a template
implementation of a singly linked list. The new class is then used in
different core modules (netif (unicast/multicast addresses), UDP6
sockets/receiver, coap resources, etc). This commit also adds a
unit test `test_linked_list` for the linked list module.
