This class can be used by F5 modules for raising exceptions.
This should be used to handle known errors and raise them so
that they can be printed in the fail_json method.
The common Exception class built-in should not be used because
it hides tracebacks that are necessary to have when debugging
problems with the module.
* Catch DistributionNotFound when pycrypto is absent
On Solaris 11, module `pkg_resources` throws `DistributionNotFound` on import if `cryptography` is installed but `pycrypto` is not. This change causes that situation to be handled gracefully.
I'm not using Paramiko or Vault, so I my understanding is that I don't
need `pycrpto`. I could install `pycrypto` to make the error go away, but:
- The latest released version of `pycrypto` doesn't build cleanly on Solaris (https://github.com/dlitz/pycrypto/issues/184).
- Solaris includes an old version of GMP that triggers warnings every time Ansible runs (https://github.com/ansible/ansible/issues/6941). I notice that I can silence these warnings with `system_warnings` in `ansible.cfg`, but not installing `pycrypto` seems like a safer solution.
* Ignore only `pkg_resources.DistributionNotFound`, not other exceptions.
With some earlier changes, continuing to forward failed hosts on
to the iterator with each TQM run() call was causing plays with
max_fail_pct set to fail, as hosts which failed in previous plays
were counting those old failures against the % calculation.
Also changed the linear strategy's calculation to use the internal
failed list, rather than the iterator, as this now represents the
hosts failed during the current run only.
This change makes it so we know when it is safe to get rid of the module
(when we stop supporting python2.4) and makes it easier for us to find
code that is using the functions in there to update.
If needed, we'll create a pycompat26 and pycompat27 as well. These
files are for functions that are needed on that python version to write
portable code. So python-2.4 compatible modules may need code in
pycompat24, python26+ modules may need code in pycompat26, etc. If
a function is needed in multiple python versions, we should implement it
in an internal common file and use import to put it in the namespace for
each pycompatXY module.
As noted in the comment, the TQM may be used for more than one play. As such,
after creating the new PlayIterator object it is necessary to mark any failed
hosts from previous calls to run() as failed in the iterator, so they are
properly skipped during any future calls to run().
Since the pyrax website say that only python 2.7 is tested,
I do not think it is worth to aim for python 2.4 compatibility
for the various rackspace modules.
Since this is now the default package manager, it got moved
to another location on Netbsd :
netbsd# type pkgin
pkgin is a tracked alias for /usr/pkg/bin/pkgin
netbsd# uname -a
NetBSD netbsd.example.org 6.1.4 NetBSD 6.1.4 (GENERIC) amd64
But since the package manager is also used outside of NetBSD, we
have to keep the /opt/local path too.
The change is needed to support the multiple include statements
inside the jinja2 template file, as in '{% include ['another.j2'] %}'.
statement. I need this capability, as OpenSwitch `switch` role needs
to handle multiple *.j2 files and supporting the include statement
inside jinja2 file is essential, otherwise I need to combine multiple
template files into a single file, which easily causes conflicts
between developers working on different parts of the teamplate, ports
and interface.
Since it depend on libcloud and libcloud requirements include python 2.6
since libcloud 0.4.0 (https://libcloud.apache.org/about.html), which
was released in 2011 Q2, and GCE drivers were added in 2013,
we can't run a libcloud version with GCE support on 2.4.
Since the modules can use a paramiko transport (ergo
python 2.4 syntax), we need to keep compat with 2.4 and python 3,
so we need to use the get_exception trick, even if the various juniper
libraries are not compatible with 2.4.
