A warning message is unsatisfying. But erroring out is too hard a failure,
especially since it may well work fine if the user has enabled passwordless
ssh.
I did think about falling back to one ssh connection at a time in this
case, but it would have needed a rework of every ssh call, which
seems far overboard for such a niche problem. There's no single place where
git-annex runs ssh, so no one place that it could block a concurrent call
on a semaphore. And, even if it did fall back to one ssh connection at a
time, it seems to me that doing so without warning the user about the
problem just invites bug reports like "git-annex is ignoring my -J2 and
only doing one download at a time". So a warning is needed, and I suppose
is good enough.
using git credential to get the password
One thing this doesn't do is wrap the password prompting inside the prompt
action. So with -J, the output can be a bit garbled.
Rather than leaking the name of the temp file, just say the config parse
failed, and where the config was downloaded from.
Not closing the bug report because two issues were reported in the same
bug report, because the universe wants me to continually re-read old
unclosed bug reports to waste my time determining what still needs to be
done.
Http remotes that do expose a git config file, but are not initialized
resulted in an ugly and unncessary error message, now sqelched.
When git-annex-shell configlist is run w/o the autoinit field, it may
not generate a uuid for the repository. So in that case, it's not
unexpected for the config it does list to not include a UUID, and
dumping out the config in a warning message is not needed.
If configlist is asked to autoinit and we don't get back a config with a
UUID in it, that suggests some problem, and what we got back may not be
a config at all but some diagnostic message, so it does make sense to
output it then.
The use case is basically the user having forgotten, so --help would be
best, but it would be quite hard to include this in --help, since it may
even have to spin up an external special remote program.
I also considered --umm but typoed it the first time I tried it as
--uum, and while memorable, it's too cutesy. --whatelse is good because
it explicitly asks, what other params, besides the ones I've given?
Special remote programs that use GETCONFIG/SETCONFIG are recommended
to implement it.
The description is not yet used, but will be useful later when adding a way
to make initremote list all accepted configs.
configParser now takes a RemoteConfig parameter. Normally, that's not
needed, because configParser returns a parter, it does not parse it
itself. But, it's needed to look at externaltype and work out what
external remote program to run for LISTCONFIGS.
Note that, while externalUUID is changed to a Maybe UUID, checkExportSupported
used to use NoUUID. The code that now checks for Nothing used to behave
in some undefined way if the external program made requests that
triggered it.
Also, note that in externalSetup, once it generates external,
it parses the RemoteConfig strictly. That generates a
ParsedRemoteConfig, which is thrown away. The reason it's ok to throw
that away, is that, if the strict parse succeeded, the result must be
the same as the earlier, lenient parse.
initremote of an external special remote now runs the program three
times. First for LISTCONFIGS, then EXPORTSUPPORTED, and again
LISTCONFIGS+INITREMOTE. It would not be hard to eliminate at least
one of those, and it should be possible to only run the program once.
This is a first step toward that goal, using the ProposedAccepted type
in RemoteConfig lets initremote/enableremote reject bad parameters that
were passed in a remote's configuration, while avoiding enableremote
rejecting bad parameters that have already been stored in remote.log
This does not eliminate every place where a remote config is parsed and a
default value is used if the parse false. But, I did fix several
things that expected foo=yes/no and so confusingly accepted foo=true but
treated it like foo=no. There are still some fields that are parsed with
yesNo but not not checked when initializing a remote, and there are other
fields that are parsed in other ways and not checked when initializing a
remote.
This also lays groundwork for rejecting unknown/typoed config keys.
