The previous wording "Already have a token - refresh?" was misleading
because answering yes triggers a full re-authorization flow, not an
OAuth2 refresh token grant. Updated to "Token already configured -
replace it?" to accurately describe what happens.
Also updated the SugarSync backend which has its own copy of the prompt,
and the docs for box, drive, and onedrive that reference it.
URLPathEscapeAll was only passing [A-Za-z0-9/] through unencoded, causing
it to percent-encode RFC 3986 unreserved characters (-, ., _, ~). Per RFC
3986 §2.3, unreserved characters MUST NOT be percent-encoded, and a URI
that unnecessarily encodes them is not equivalent to one that does not.
Servers that perform strict path matching without normalising
percent-encoded characters will reject the over-encoded form with a 404.
Before: /files/my-report.pdf → /files/my%2Dreport%2Epdf
After: /files/my-report.pdf → /files/my-report.pdf
Reserved characters (spaces, semicolons, colons, etc.) continue to be
encoded as before.
Before this change server side copies would show at 0% until they were
done then show at 100%.
With support from the backend, server side copies can now be accounted
in real time. This will only work for backends which have been
modified and themselves get feedback about how copies are going.
If the transfer fails, the bytes accounted will be reversed.
Add gzip compression for directory listings and text assets served over HTTP.
This reduces the rclone repository file listing from 40 kB to 8 kB and reduces
the rclone MANUAL.txt from 2.7 MB to 700 kB.
This makes listings and assets served across the network load faster.
The compression level of 5 should be a good balance between size and speed.
The WebDAV implementation already permits redirects on PROPFIND for
listing paths in the `listAll` method but does not permit this for
metadata in `readMetaDataForPath`. This results in a strange experience
for endpoints that heavily use redirects -
```
rclone lsl endpoint:
```
functions and lists `hello_world.txt` in its output but
```
rclone lsl endpoint:hello_world.txt
```
Fails with a HTTP 307.
The git history for this setting indicates this was done to avoid
an issue where redirects cause a verb change to GET in the Go HTTP
client; it does not appear to be problematic with HTTP 307.
To fix, a new `CheckRedirect` function is added in the `rest` library
to force the client to use the same verb across redirects, forcing this
for the PROPFIND case.
Before this change we read sleepTime before acquiring the pacer token
and uses that possibly stale value to schedule the token return. When
many goroutines enter while sleepTime is high (e.g., 10s), each
goroutine caches this 10s value. Even if successful calls rapidly
decay the pacer state to 0, the queued goroutines still schedule 10s
token returns, so the queue drains at 1 req/10s for the entire herd.
This can create multi‑minute delays even after the pacer has dropped
to 0.
After this change we refresh the sleep time after getting the token.
This problem was introduced by the desire to skip reading the pacer
token entirely when sleepTime is 0 in high performance backends (eg
s3, azure blob).
It was possible in the presence of --max-connections and recursive
calls to the pacer to deadlock it leaving all connections waiting on
either a max connection token or a pacer token.
This fixes the problem by making sure we return the pacer token on
schedule if we take it.
This also short circuits the pacer token if sleepTime is 0.
* Adds "aix/ppc64" to the cross-compile target list.
* Including AIX in the build tag of "metadata_other.go".
* Excluding AIX from the main ncdu build tags.
* Marking AIX as an unsupported platform for ncdu.
* Excluding AIX from the fallback redirect implementation.
* Excluding AIX from unix build tags to avoid undefined unix.WNOHANG.
If the pacer was used recursively and --max-connections was in use
then it could deadlock if all the connections were in use at the time
of recursive call (likely).
This affected the azureblob backend because when it receives an
InvalidBlockOrBlob error it attempts to clear the condition before
retrying. This in turn involves recursively calling the pacer.
This fixes the problem by skipping the --max-connections check if the
pacer is called recursively.
The recursive detection is done by stack inspection which isn't ideal,
but the alternative would be to add ctx to all >1,000 pacer calls. The
benchmark reveals stack inspection takes about 55nS per stack level so
it is relatively cheap.
This turned out to be a problem in the tests. The tests used to do
1. allocate
2. increment
3. free
4. decrement
But if one goroutine had just completed 2 and another had just
completed 3 then this can cause the test to register too many
allocations.
This was fixed by doing the test in this order instead:
1. allocate
2. increment
3. decrement
4. free
The 4 operations are atomic.
Fixes#8813
Before this change we used an overcomplicated method of memory
reservations in the pool.RW which caused deadlocks.
This changes it to use a much simpler reservation system where we
actually reserve the memory and store it in the pool.RW. This allows
us to use the semaphore.Weighted to count the actually memory in use
(rather than the memory in use and in the cache). This in turn allows
accurate use of the semaphore by users wanting memory.
Because multipart transfers can need more than one buffer to complete,
if transfers was set very high, it was possible for lots of multipart
transfers to start, grab fewer buffers than chunk size, then deadlock
because no more memory was available.
This fixes the problem by introducing a reservation system which the
multipart transfer uses to ensure it can reserve all the memory for
one chunk before starting.
All user visible Durations should be fs.Duration rather than time.Duration. Suffix is then optional and defaults to s. Additional suffices d, w, M and y are supported, in addition to ms, s, m and h - which are the only ones supported by time.Duration. Absolute times can also be specified, and will be interpreted as duration relative to now.
