Based on the last three comments on this thread it was going to keep
collecting complaints from people who glanced at the thread, did not
notice it was for an old, solved issue, and decided to followup.
Also, the tone of this thread, while very constructive in some places,
is very very outraged in others. This apparently leads people to feel
that randomly saying they don't trust me is a reasonable thing to post
at the end of a long thread they have not bothered to read all of, by
their own admission.
So this thread seems to have become a source of confusion for users, and
a source of pain and disincentive to worm on git-annex for me. Yes, I'm
taking the rest of today to go do something actually fun obviously.
Fix bug that made enableremote of S3 and webdav remotes, that have
embedcreds=yes, fail to set up the embedded creds, so accessing the remotes
failed.
(Regression introduced in version 7.20200202.7 in when reworking all the
remote configs to be parsed.)
Root problem is that parseEncryptionConfig excludes all other config keys
except encryption ones, so it is then unable to find the
credPairRemoteField. And since that field is not required to be
present, it proceeds as if it's not, rather than failing in any visible
way.
This causes it to not find any creds, and so it does not cache
them. When when the S3 remote tries to make a S3 connection, it finds no
creds, so assumes it's being used in no-creds mode, and tries to find a
public url. With no public url available, it fails, but the failure doesn't
say a lack of creds is the problem.
Fix is to provide setRemoteCredPair with a ParsedRemoteConfig, so the full
set of configs of the remote can be parsed. A bit annoying to need to
parse the remote config before the full config (as returned by
setRemoteCredPair) is available, but this avoids the problem.
I assume webdav also had the problem by inspection, but didn't try to
reproduce it with it.
Also, getRemoteCredPair used getRemoteConfigValue to get a ProposedAccepted
String, but that does not seem right. Now that it runs that code, it
crashed saying it had just a String.
Remotes that have already been enableremoted, and so lack the cached creds
file will work after this fix, because getRemoteCredPair will extract
the creds from the remote config, writing the missing file.

One way this can be used is to remove all urls for some website that went
away:
git-annex whereis --format '${file} ${url}\0' | \
grep -z whatever.com | git-annex rmurl --batch -z
Combining ${url} and ${uuid} is a bit of a combinatorial explosion.
It didn't seem worth only outputting a uuid alongside an url belonging
to it, so each uuid is output beside each url.
Finishes the transition to make remote methods throw exceptions, rather
than silently hide them.
A bit on the fence about this one, because when renameExport fails,
it falls back to deleting instead, and so does the user care why it failed?
However, it did let me clean up several places in the code.

When storing content on remote fails, always display a reason why.
Since the Storer used by special remotes already did, this mostly affects
git remotes, but not entirely. For example, if git-lfs failed to connect to
the endpoint, it used to silently return False.
