This returns a cached version of the new rtutil.RT class,
so that a single process can easily grab references to one
instance with one cache of ticket/attachment data, etc.
For now, this is basically the Python version of
ledger-tag-convert.plx. It knows how to create RT web links from
ticket and attachment IDs. It confirms that those objects actually
exist too. It may grow to encompass other functionality in the
future.
The socks package in Debian buster does a deprecated import from
the collections module. That's not directly relevant to our own
code (Conservancy has no business requirement for SOCKS support)
so ignore it.
This loads settings from the same environment variables and ~/.rtrc
file as the rt CLI.
Note that it does *not* support RTCONFIG and the config file
searching, because right now that seems like more work for more
trouble to me.
As we start reading more sensitive user configuration (like RT credentials),
this fixture makes it simpler to ensure that the tests never read the user's
real configuration, which could lead to problems like passwords in tracebacks.
Our version of Posting is interface-compatible with Beancount's,
but makes stronger guarantees about the data types for our
higher-level code to rely on.
As I'm pushing to reimplement payment-report/income-report, I see query and
reporting tools will want easy access to these kinds of views, so here it
starts.
* Rename _typing to beancount_types to better reflect what it is.
* LessComparable isn't a Beancount type, so move that to
plugin.core with its dependent helper classes.
* Errors are a core Beancount concept, so move that module to the
top level and have it include appropriate type definitions.
I feel like posting hooks a case of premature optimization in early
development. This approach reduces the number of special cases in
the code and allows us to more strongly reason about hooks in the
type system.
