When a Proton Drive file has no active revision attributes,
readMetaDataForLink returns a nil FileSystemAttrs and Object.originalSize
is left as nil. Object.Open then dereferenced this nil pointer when
calling fs.FixRangeOption, causing a SIGSEGV during copy.
Use Object.Size() instead, which already implements the correct fallback
to the link size when originalSize is unavailable.
This updates the github.com/rclone/Proton-API-Bridge package to fix a
segfault when reading files with no metadata.
Fixes#9377Fixes#9117
Previously all log output produced by Proton-API-Bridge (stdlib log)
and go-proton-api (logrus + resty's logger) bypassed rclone's
logging: it ignored -v / -vv levels and didn't reach --log-file.
Add a small adapter implementing the resty.Logger / bridge Logger
shape that calls fs.Errorf / fs.Logf / fs.Debugf, and pass it via
the new Config.Logger hook. The bridge in turn forwards the same
value to go-proton-api's WithLogger option, so HTTP-layer warnings
and the formerly-hardcoded logrus warnings inside go-proton-api
also surface through rclone's log levels.
The Proton Drive backend constructed the upstream Proton-API-Bridge
without ever passing rclone's HTTP transport. As a result none of
rclone's HTTP flags reached Proton: --dump headers, --dump bodies,
--no-check-certificate, --user-agent, --bind, --ca-cert, --header,
--tpslimit etc. all silently did nothing for this remote, and HTTP
traffic was invisible to -vv.
Pass fshttp.NewTransport(ctx) through the new Config.Transport hook on
the bridge, which forwards it to the updated go-proton-api's
WithTransport option and so to the underlying resty client.
This updates rclone to use forks of the upstream proton drive modules
in preparation for making changes.
The go-proton-api modules has had changes from master merged so rclone
and Proton-API-Bridge are using the same version.
This change removes redundant calls to the Proton Drive Bridge when
creating Objects. Specifically, the function List() would get a
directory listing, get a link for each file, construct a remote path
from that link, then get a link for that remote path again by calling
getObjectLink() unnecessarily. This change removes that unnecessary
call, and tidies up a couple of functions around this with unused
parameters.
