changes:
- chunker: remove GetTier and SetTier
- remove wdmrcompat metaformat
- remove fastopen strategy
- make hash_type option non-advanced
- adverise hash support when possible
- add metadata field "ver", run strict checks
- describe internal behavior in comments
- improve documentation
note:
wdmrcompat used to write file name in the metadata, so maximum metadata
size was 1K; removing it allows to cap size by 200 bytes now.
In 53a1a0e3ef we introduced a problem where if there was an
error on the file being transferred then the file was re-opened and
the old one wasn't closed.
This was partially fixed in bfbddab46b however this didn't
address the case of the old file being closed.
This is now fixed by
- marking the file as open again in UpdateReader
- moving the stopping the accounting machinery to a new method Done
Before this change you could only configure the local backend flags
which don't have the local prefix (eg `--copy-links`) with
`RCLONE_LOCAL_COPY_LINKS`.
This change makes `RCLONE_COPY_LINKS` valid too which is much more
logical for the users.
Fixes#3534
Before this change it was possible to make a remote with an invalid
name in the config file, either manually or with `rclone config
create` (but not with `rclone config`).
When this remote was used, because it was invalid, rclone would
presume this remote name was a local directory for a very suprising
user experience!
This change checks remote names more carefully and returns errors
- when the user tries to use an invalid remote name on the command line
- when an invalid remote name is used in `rclone config create/update/password`
- when the user tries to enter an invalid remote name in `rclone config`
This does not prevent the user entering a remote name with invalid
characters in the config manually, but such a remote will fail
immediately when it is used on the command line.
Before this change, using -P occasionally deadlocked on the Transfer
mutex when Transfer.Done() was called with a non nil error and the
StatsInfo mutex since they mutually call each other.
This was fixed by making sure that the Transfer mutex is always
released before calling any StatsInfo methods.
This improves on: 6f87267b34Fixes#3505
Before this change if -u/--update was in effect we compared the size
of the files to see if the transfer should go ahead. This was
comparing -1 with an actual size so the transfer always proceeded.
After this change we use the existing `sizeDiffers` function which
does the correct comparison with -1 for files of unknown length.

Without this patch the resulting error is first converted to string and then recreated.
This makes it impossible to use the defined error types to figure out the cause of the error,
and may result in invalid HTTP status codes.
This patch adds a test TestExecuteJobErrorPropagation to validate that the errors are
properly propagated.
Before this change we didn't calculate or check hashes of transferred
files if --size-only mode was explicitly set.
This problem was introduced in 20da3e6352 which was released with v1.37
After this change hashes are checked for all transfers unless
--ignore-checksums is set.
Before this change we calculated the checkums when using
--ignore-checksum but ignored them at the end.
Now we don't calculate the checksums at all which is more efficient.
Before this change for a post copy Hash check we would run the hashes sequentially.
Now we run the hashes in parallel for a useful speedup.
Note that this refactors the hash check in Copy to use the standard
hash checking routine.
The error "tls: bad record MAC" is very likely to be caused by
hardware issues. It indicates that a packet got corrupted somewhere.
As a work around, this change treats it as retriable error which
allows the chunk to get retried and the transfer to continue.
See: https://forum.rclone.org/t/rc-rc-job-expire-interval-bug/11188
rclone was ignoring the --rc-job-expire-duration and --rc-job-interval
flags. This turned out to be an initialization order problem and was
fixed by moving those flags out of global config into rc config.
