When extsort.Strings() cannot create temporary files (e.g. due to
apparmor restrictions or permission denied), it returns a nil sorter
with the error on errChan. The code then called Sort() on the nil
sorter, causing a panic.
Check for nil sorter and return the error instead of panicking.
Fixes#9244
The format field was read in Handle() without synchronization while
setFormat() could write it concurrently from InitLogging(). This
caused a data race detected by the race detector, failing
TestListBucketsAuthProxy in cmd/serve/s3.
Fix by protecting all access to format with the existing mutex.
This adds 11 previously-missing rc params for newer bisync features.
It also makes optional parameters truly optional. (Previously, callers were
required to supply every single one, even if using the default value.)
This reduces the number of go routines which can get out of hand when
using large --transfers and --multi-thread-streams from potentially
--multi-thread-streams * --transfers Go routines to --max-memory /
--multi-thread-chunk-size
It serializes the memory allocator in each transfer which should be
good for performance and reduce lock contention.
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.
Fixes#5063 by documenting that S3 object keys containing
consecutive forward slashes (//) are not supported by rclone.
The issue occurs because rclone normalizes paths like "a//b" to "a/b",
causing "object not found" errors when trying to access the original
object. This documentation addition explicitly warns users about this
limitation and provides workarounds.
Changes:
- Added new subsection "Important note about double slashes (//)"
under "Restricted filename characters" in S3 documentation
- Explains the normalization behavior and its consequences
- Provides clear examples and workarounds
