Before this patch chunker required that there is at least one
data chunk to start checking for a composite object.
Now if chunker finds at least one potential temporary or control
chunk, it marks found files as a suspected composite object.
When later rclone tries a concrete operation on the object,
it performs postponed metadata read and decides: is this a native
composite object, incompatible metadata or just garbage.
Before this change stable releases updated the current beta which mean
confusingly the current beta release would jump backwards from
1.54.0-beta to 1.53.3-beta say.
This commit stops any tagged build making a current beta release. They
will still make beta releases, they just won't update the
rclone*current*.zip and version.txt files.
This also means that a .0 release will not make a current beta like it
does at the moment.
This shouldn't be read as encouraging the use of math/rand instead of
crypto/rand in security sensitive contexts, rather as a safer default
if that does happen by accident.
For some reason the API started returning some integers as strings in
JSON. This is probably OK in Javascript but it upsets Go.
This is easily fixed with the `json:"name,size"` struct tag.
A security problem was discovered when using set-env and
set-path. This has been deprecated by GitHub and a new mechanism
introduced.
This patch switches to using the new mechanism which will stop GitHub
warning about the use of the old mechanism.

Occasionally the b2 tests fail because the integration tests don't
retry hard enough with their new setting of -list-retries 3. Override
this setting to 5 for the b2 tests only.
Before this change rclone returned the size from the Stat call of the
link. On Windows this reads as 0 always, however on unix it reads as
the length of the text in the link. This caused errors like this when
syncing:
Failed to copy: corrupted on transfer: sizes differ 0 vs 13
This change causes Windows platforms to read the link and use that as
the size of the link instead of 0 which fixes the problem.
The missed update can cause incorrect before-cleaning cache stats
and a pre-mature condition broadcast in purgeOld before the cache
space use is reduced below the quota.
Add an exponentially increasing delay during retries up ENOSPC error
to avoid exhausting the 10 retries too soon when the cache space
recovery from item resets is not available from the file system yet
or consumed by other large cache writes.
Item reset is invoked by cache cleaner for synchronous recovery
from ENOSPC errors. The reset operation removes the cache file and
closes/reopens the downloaders. Although most parts of reset and
other item operations are done with the item mutex held, the mutex
is released during fd.WriteAt and downloaders calls. We used preAccess
and postAccess calls to serialize Reset, ReadAt, and Open, but missed
some other item operations. The patch adds preAccess/postAccess
calls in Sync, Truncate, Close, WriteAt, and rename.
A failed item reset is saved in the errItems for retryFailedResets
to process. If the item gets closed before the retry, the item may
have been removed from the c.item array. Previous code did not
account for this condition. This patch adds the check for the
exitence of the retry items in retryFailedResets.
The downloaders.Close() call acquires the downloaders' mutex before
calling the wait group wait and the main downloaders thread has a
periodical (5 seconds interval) call to kick its waiters and the
waiter dispatch function tries to get the mutex. So a deadlock can
occur if the Close() call starts, gets the mutex, while the main
downloader thread already got the timer's tick and proceeded to
call kickWaiters. The deadlock happens when the Close call gets
the mutex between the timer's kick and the main downloader thread
gets the mutex first. So it's a pretty short period of time and
it probably explains why the problem has not surfaced, maybe
something like tens of nanoseconds out of 5 seconds (~10^^-8).
It took 5 days of continued stressing the Close calls for the
deadlock to appear.
Before this change rclone would emit the message
--checksum is in use but the source and destination have no hashes in common; falling back to --size-only
When the source or destination hash was missing as well as when the
source and destination had no hashes in common.
This first case is very confusing for users when the source and
destination do have a hash in common.
This change fixes that and makes sure the error message is not emitted
on missing hashes even when there is a hash in common.

Before this change we sorted transfers in the stats list solely on
time started. However if --check-first was in use then lots of
transfers could be started in the same millisecond. Because Windows
time resolution is only 1mS this caused the entries to sort equal and
bounce around in the list.
This change fixes the sort so that if the time is equal it uses the
name which should stabilize the order.
Fixes#4599
