[pbs-devel] [PATCH proxmox-backup] http_client: keep renewal future running on failed re-auth

[Fabian Grünbichler]

there's a small typo in the commit message (necesarrily). in general, it
could have been structured a bit more readable ;) e.g.,

It is okay to treat a failure to refresh the authentication ticket as
non-fatal, since it is either spurious and other requests including the
next refresh will work (in which case, erroring out the whole client is
premature), or all requests will fail, in which case the client will
error out shortly anyway.

a second pair of eyes to ensure I haven't missed any peculiarity here
wouldn't hurt, since this is potentially security sensitive code, albeit
the chances should be low.
