Before this change if using --fast-list on a directory with more than
a few thousand directories in it DirTree.CheckParents became very slow
taking up to 24 hours for a directory with 1,000,000 directories in
it.
This is because it becomes an O(N²) operation as DirTree.Find has to
search each directory in a linear fashion as it is stored as a slice.
This patch fixes the problem by scanning the DirTree for directories
before starting the CheckParents process so it never has to call
DirTree.Find.
After the fix calling DirTree.CheckParents on a directory with
1,000,000 directories in it will take about 1 second.
Anything which calls DirTree.Find can potentially have bad performance
so in the future we should redesign the DirTree to use a different
underlying datastructure or have an index.

This reverts commit 9065e921c1.
It turns out the problem for the failing fs/sync tests was the
policies being different for search and create which meant that the
file was being created in one union branch but a diferent one was
found in another branch.
The API seems to have changed and the `totalFileCount` item no longer
tracks the number of files in the directory so is useless for seeing
if the directory is empty.
This patch fixes the problem by seeing whether there are any files or
directories in the folder instead.
This problem was detected by the integration tests.
For some unknown reason the API sometimes returns the name already
exists on a server side copy.
{
"error_id": null,
"error_message": "Name already exist",
"error_type": "NAME_ALREADY_EXIST",
"error_uri": "http://api.put.io/v2/docs",
"extra": {},
"status": "ERROR",
"status_code": 400
}
This patch uploads to a temporary name then renames it which works
around the problem.
This was spotted by the integration tests.
The integration tests spotted that modification times are no longer
being preserved by the putio API in server side move and copy.
This patch explicitly sets the modtime after the server side move or
copy.
In this commit we enabled PartialUploads for the union backend.
3faa84b47c combine,compress,crypt,hasher,union: support wrapping backends with PartialUploads
This turns out to cause test failures in fs/sync so this commit
disables them again pending further investigation.
At some point the sharefile API changed to require the size of the
file in the initial transaction which makes the streaming upload fail
with this error:
upload failed: file size does not match (-2)
This was discovered by the integration tests.
In this commit we discovered a problem with objects being uploaded to
the incorrect object name. It added an integration test for the
problem.
65b2e378e0 drive: fix incorrect remote after Update on object
This test was tripped by the putio backend and this patch fixes the
problem.
Before this patch the Update method had a 50/50 chance of returning
the old object rather than the new updated object.
This was discovered in the integration tests.
This patch fixes the problem by deleting the duplicate object before
we look for the new object.
In this commit we discovered a problem with objects being uploaded to
the incorrect object name. It added an integration test for the
problem.

This test was tripped by the Storj backend and this patch fixes the
problem.
Storj has a rate limit of 1 per second when uploading to the same
file.
This was being tripped by the integration tests.
This patch fixes it by detecting the error and sleeping for 1 second
before retrying.

Before this change a server side copy did not preserve the modtime.
This used to work on nextcloud but at some point it started ignoring
the `X-Oc-Mtime` header.
This patch sets the modtime explicitly after a server side copy if the
`X-Oc-Mtime` wasn't accepted.
This problem was discovered in the integration tests.
when multi-thread downloading is enabled, rclone used
to send a write to disk after every read, resulting in a lot
of small writes to different locations of the file.
depending on the underlying filesystem or device, it can be more
efficient to send bigger writes.
Before this change we were incorrectly identifying the root directory
of the listing and adding it into the listing.
This caused higher layers of rclone to emit the error above.

This commit
3567a47258 fs: make ConfigString properly reverse suffixed file systems
made fs.ConfigString() return the full config of the backend. Because
mount was using this to make a volume name it started to make volume
names with illegal characters in which couldn't be mounted by macOS.
This fixes the problem by making a separate fs.ConfigStringFull() and
using that where appropriate and leaving the original
fs.ConfigString() function untouched.
Fixes#7063
