this is such a crude hack it is totally embarrassing....
the proper solution would probably be to move the `build_parser()`
function out of `Archiver` completely, but this is such an undertaking
that i doubt it is worth doing since we're looking at switching to
click anyways.
the main problem in moving build_parser() out is that it references
`self` all the time, so it *needs* an archiver context that it can
reuse. we could make the function static and pass self in there by
hand, but it seems like almost a worse hack... and besides, we would
need to load the archiver in order to do that, which would break usage
all over again...
this is an unfortunate rewrite of the manpage creation code mentionned
in #208. ideally, this would be rewritten into a class that can
generate both man pages and .rst files.
first off, this required ticking the `Install your project inside a
virtualenv using setup.py install` box in the advanced config.
then, i had to disable all the C extensions build and disable some
checks, based on whether we are running on RTD or not.
still missing: usage builds and possibly other stuff that is in our
Makefile and not in setup.py.
link to the locations of different tools when I know them. i marked
the ones I don't know about specially so we can document those as
well.
point to the Github releases for the standalone binaries upload
we stop supporting them, because there are better alternatives:
- use a distribution package (from your linux distribution), if available
- use a pyinstaller binary provided by us (they include all you need in 1 file and
thus have better compatibility properties and are easier to install than a wheel)
- install from source (pypi or git) if everything else fails
while SSH options can be specified through `~/.ssh/config`, some users
may want to use a completely different SSH command for their backups,
without overriding their $PATH variable. it may also be easier to do
ad-hoc configuration and tests that way.
plus, the POLA tells us that users expects something like this to be
supported by commands that talk to ssh. it is supported by rsync, git
and so on.
the reasoning behind this is that we may need to test a
RemoteRepository setup outside of the main archiver routines, which
the current default location makes impossible
by moving the umask and remote_path remotes into the RemoteRepository
the (reasonable) defaults are available regardless of the (currently
obscure) initialisation routine, and make unit tests easier to develop
and support
Code shared by read() and iter_objects() was moved into _read().
Compared to read()'s previous state, this improved:
- fixed size check to avoid read with negative size
- exception handler for struct unpack
- checking for short read
- more precise exception messages
