Some webdav backends (eg rclone serve webdav) leave behind half
written files on error. This causes the integration tests to
fail. Here we remove the file if it exists.
This change to go1.11 causes the TestFsPutError test to fail
https://go-review.googlesource.com/c/go/+/114316
This is because it now passes the half written file to the backend
whereas it didn't previously because of the buffering.
In this commit the size of the data written was increased to 5k from
50 bytes to provoke the test failure under go1.10 also.
Sometimes it takes many more commit retries than expected to commit a
multipart file, so split this number into its own config variable and
default it to 100 which should always be enough.
vfs/refresh will walk the directory tree for the given paths and
freshen the directory cache. It will use the fast-list capability
of the remote when enabled.
this change adds the depth parameter to listAll and readMetaDataForPath.
this allows recursive calls of these methods with a different depth
header.
Sharepoint won't list files if the depth header is != 0. If that is the
case, it will just return a error 404 although the file exists.
Since it is not possible to determine if a path should be a file or a
directory, rclone has to make a request with depth = 1 first. On success
we are sure that the path is a directory and the listing will work.
If this request returns error 404, the path either doesn't exist or it
is a file.
To be sure, we can try again with depth set to 0. If it still fails, the
path really doesn't exist, else we found our file.
Before this change the Part structure had an int for the Offset and
uploading large files would produce this error
json: cannot unmarshal number 2147483648 into Go struct field Part.offset of type int
Changing the field to an int64 fixes the problem.
By default the timeout is 60s which isn't long enough for long
transactions. The symptoms are rclone just quitting for no reason.
Supplying the --daemon-timeout flag fixes this causing the kernel to
wait longer for rclone.
