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?
Avoids the external program being started just to use LISTCONFIGS on an
already accepted config.
So initremote/enableremote will still run the external program an extra
time to use LISTCONFIGS, but everything that uses the special remote after
it's initialized will not any longer.
getRemoteConfigPassedThrough was never returning anything, Typeable
prevented the type checker from noticing a dumb mistake.
parseRemoteConfig was not adding Accepted values as PassedThrough
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 code worked as intended, but only by accident, because of this
instance:
instance Monoid b => Monoid (x -> b) where mempty = const (mempty :: b)
Let's be explicit that we throw away the error message.
The benefit here is that external special remotes will need a
LISTCONFIGS request and response to generate their config parser,
and this avoids it being done for all the ones that don't have any
configs.
Note that, a config parser could in theory fail to parse if there are no
configs (none currently do), but a parse failure is already thrown away
when generating the remote list because it's too late. Such problems
have to be caught at initremote/enableremote time, not here.
Not yet added anything to the protocol to get a list of remote config
fields; any fields will be accepted and are available for the external
remote to use as before.
There is one minor behavior change.. Before, GETCONFIG could be passed a
field such as type, externaltype, encryption, etc, and would get the
value of that. Now, GETCONFIG only works on fields that don't have a
defined meaning to git-annex, so are passed through to the external
remote. This seems unlikely to affect any external special remotes in
practice.
preferreddir can be used with any special remote, so its parser needs to
be included in the commonFieldParsers.
initremote with uuid= changed to delete that field, so it does not
need to be included in commonFieldParsers. Note that, existing remotes
initialized before this change will have the field in remote.log.
This will not cause problems parsing, because the value will be
Accepted.
Grepping for 'Accepted "' found these, and I'm pretty sure this is all of
them.
Using field functions consistently avoids possibility of typos and also
helps ensure that all fields are added to RemoteConfigParsers (as long
as I have remembered to add them when writing the functions).
Avoids parse error when the fields are added to RemoteConfig at setup
time and it then gets parsed, also at setup time. After setup time, such
internally added fields are not a problem, because they're Accepted. So
it may not be necessary in all cases to list such internally added
fields, but I think it's a good idea to always do so.
