Issue:
Use std::allocator_traits<ContainerAllocator>::template rebind instead of ContainerAllocator::template rebind
`allocator_traits` is not available till C++11, so this might be in the backlog for a while. Switching conditionally on the compiler version might be reasonable.

Using `::rebind` directly on the type is deprecated as of C++17.

Thankfully, no changes are needed to `ContainerAllocator` to make this work.


Discussion:
Please consider to provide a pull request for this.
Is there precedent elsewhere in ROS for checking for C++ features before using them?
I don't think that is necessary. Assuming that the change is within a `.cpp` file ROS Kinetic and newer already require a C++11 compiler. So it should be safe to use.
I really need to start pushing to move off indigo!

Issue:
roslaunch gives deceptive error if chmod +x isn't set
Trying to `roslaunch pack_name launcher.launch` fails with the following error if your source file exists in the appropriate spot, but does not have `+x` permission set. 

```
ERROR: cannot launch node of type [pack_name/node_name.py]: 
can't locate node [node_name.py] in package [pack_name]
```

Looks like it is from: 

https://github.com/ros/ros_comm/blob/eb7e686a9a58109087c956eed3cfa6f2ed3eec3d/tools/roslaunch/src/roslaunch/node_args.py#L256

I spent a lot of time mucking around with path, ENV, packages.xml, namespaces, and the launch file, thinking it is a problem with a path or naming scheme. Once you know what you are looking for, it is obvious from questions on the wiki that this is a [commonly](https://answers.ros.org/question/244463/errorcannot-launch-node-of-typetesttestcannot-locate-node-test-in-package-test/) [encountered](https://answers.ros.org/question/209426/i-cant-launch-a-node/) [problem](https://answers.ros.org/question/241690/roslaunch-error-error-cannot-launch-node-of-type/). 

If the file is `+x` but lacks a shebang, the more helpful error occurs:

```
Unable to launch [foo/image_nexus_node-2]. 
If it is a script, you may be missing a '#!' declaration at the top.
```
Could someone add a more useful helper text here to indicate that this might be a permission error and not a path error? Perhaps: 

```
raise NodeParamsException("can't locate node [%s] in package [%s]. 
Make sure file exists in package path and permission is set to executable (chmod +x)"
%(node.type, node.package))
```

Issue:
 ROSBagException should call the base constructor
In python 2.7 there is a subtle bug with unpickling custom exceptions; this was fixed in 3.3, see https://bugs.python.org/issue1692335.  As a workaround for 2.7 we can re-define these exceptions as below.

```java
class ROSBagException(Exception):
    """
    Base class for exceptions in rosbag.
    """
    pass
 
class ROSBagFormatException(ROSBagException):
    """
    Exceptions for errors relating to the bag file format.
    """
    pass

class ROSBagUnindexedException(ROSBagException):
    """
    Exception for unindexed bags.
    """
    def __init__(self, *args):
        ROSBagException.__init__(self, 'Unindexed bag')
```

For context, I came across this issue when a `ROSBagUnindexedException` was raised in a `multiprocessing.Pool.map` thread.  It throws the `__init__` exception and hangs, as described here: https://lists.gt.net/python/bugs/1025933


Discussion:
Can you please provide a pull request with the proposed patch against the current default branch (`lunar-devel`). Thanks.

Issue:
Coverity - forward null
Event null_check: Comparing "f" to a null-like value implies that "f" might be null-like.
https://github.com/ros/ros_comm/blob/29053c4832229efa7160fb944c05e3bc82e11540/tools/rosgraph/src/rosgraph/roslogging.py#L61-L62

Event property_access: | Accessing a property of null-like value "f".
https://github.com/ros/ros_comm/blob/29053c4832229efa7160fb944c05e3bc82e11540/tools/rosgraph/src/rosgraph/roslogging.py#L76

There is a path for a null-valued variable to be dereferenced. But "f" might still be None
