fs.CountError is called when an error is encountered. The method was
calling GlobalStats().Error(err) which incremented the error at the
global stats level. This led to calls to core/stats with group= filter
returning an error count of 0 even if errors actually occured.
This change requires the context to be provided when calling
fs.CountError. Doing so, we can retrieve the correct StatsInfo to
increment the errors from.
Fixes#5865
Before this change, when cache.GetFn was called on a file rather than a
directory, two cache entries would be added (the file + its parent) but only one
of them would get pinned if the caller then called Pin(f). This left the other
one exposed to expiration if the ci.FsCacheExpireDuration was reached. This was
problematic because both entries point to the same Fs, and if one entry expires
while the other is pinned, the Shutdown method gets erroneously called on an Fs
that is still in use.
An example of the problem showed up in the Hasher backend, which uses the
Shutdown method to stop the bolt db used to store hashes. If a command was run
on a Hasher file (ex. `rclone md5sum --download hasher:somelargefile.zip`) and
hashing the file took longer than the --fs-cache-expire-duration (5m by default), the
bolt db was stopped before the hashing operation completed, resulting in an
error.
This change fixes the issue by ensuring that:
1. only one entry is added to the cache (the file's parent, not the file).
2. future lookups correctly find the entry regardless of whether they are called
with the parent name or one of its children.
3. fs.ErrorIsFile is returned when (and only when) fsString points to a file
(preserving the fix from 8d5bc7f28b).
Note that f.Root() should always point to the parent dir as of c69eb84573
It fails to build on plan9, which is part of the rclone CI matrix, and
the PR fixing it upstream doesn't seem to be getting traction.
Stub it on our side, we can still remove this once it gets merged.
Instead of the listening addresses specified above, rclone will listen to all
FDs passed by the service manager, if any (and ignore any arguments passed by
`--{{ .Prefix }}addr`.
This allows rclone to be a socket-activated service. It can be configured as described in
https://www.freedesktop.org/software/systemd/man/latest/systemd.socket.html
It's possible to test this interactively through `systemd-socket-activate`,
firing of a request in a second terminal:
```
❯ systemd-socket-activate -l 8088 -l 8089 --fdname=foo:bar -- ./rclone serve webdav :local:test/
Listening on [::]:8088 as 3.
Listening on [::]:8089 as 4.
Communication attempt on fd 3.

This changes log statements from log to fs package, which is required for --use-json-log
to properly make log output in JSON format. The recently added custom linting rule,
handled by ruleguard via gocritic via golangci-lint, warns about these and suggests
the alternative. Fixing was therefore basically running "golangci-lint run --fix",
although some manual fixup of mainly imports are necessary following that.
Starting with go1.22 the standard os.MkdirAll has improved its handling of volume names,
and as part of that it now stops recursing into parent directory if it is a volume name
(see: cd589c8a73).
This is similar to what was our main change and reason for creating a custom version. When
building with go1.22 or newer we can therefore stop using our custom version, with the
advantage that we automatically get current and future relevant improvements from golang.
To support building with go1.21 the existing custom version is still kept, and therefore
also our wrapper function file.MkdirAll - but it now just calls os.MkdirAll with go1.22
or newer on Windows.
See #5401, #6420 and acf1e2df84 for details about the
creation of our custom version of MkdirAll.
We upgraded our minimum Go version in commit ca24447090. We can now use
the built-in `min` and `max` functions directly.

There were a lot of instances of this lint error
printf: non-constant format string in call to github.com/rclone/rclone/fs.Logf (govet)
Which were fixed by re-arranging the arguments and adding "%s".
There were quite a few genuine bugs which were found too.
reflect.SliceHeader is deprecated, however the replacement gives a go
vet warning so this disables the lint warning in one use of
reflect.SliceHeader and replaces it in the other.
This prevents an `rclone rcd` server from prematurely going into the
'deactivating' state, which was causing systemd to kill it with a
SIGABRT after the stop timeout.
Fixes#7540
The vfs use the hardcoded OS encoding when creating temp file,
but decode it with encoding for the local filesystem (--local-encoding)
when copying it to remote.
This caused failures when the filenames contained special characters.
The hardcoded OS encoding is now used uniformly.
On Windows, this change includes the `FILE_FLAG_BACKUP_SEMANTICS` in
all calls to `CreateFile`.
Adding this flag allows is useful when rclone is running within a
security context that has `SeBackupPrivilege` and/or `SeRestorePrivilege`
token privileges enabled.
Without this flag, rclone cannot properly leverage special security
groups such as Backup Operators who possess the these privileges.
See: https://forum.rclone.org/t/rclone-sebackupprivilege-file-flag-backup-semantics/45339
See: https://github.com/rclone/rclone/pull/7877.
When an external OAuth flow is being used (i.e. a client ID and an
OAuth token are set in the config), a client secret should not be set.
If one is, the server may reject a token refresh attempt.
But there's no way to clear out a backend's default client secret via
configuration, since empty-string config values are ignored.
So instead, when a client ID is set, we should clear out any default
client secret, since it wouldn't apply anyway.
Windows webdav does an OPTIONS request on the root even when given a
path and if we return 404 here then Windows refuses to use the path.
This patch allows OPTIONS requests only on the root to fix this.
This affects all the HTTP servers.
Before this change it wasn't possible to see where transfers were
going from and to in core/stats and core/transferred.
When use in rclone mount in particular this made interpreting the
stats very hard.
the field `raw` of `oauth2.Token` may be an uncomparable type(often map[string]interface{}), causing `*token != *ts.token` expression to panic(comparing uncomparable type ...).
the semantics of comparing whether two tokens are the same can be achieved by comparing accessToken, refreshToken and expire to avoid panic.
Before this change multi-thread copies using the FTP backend used to error with
551 Error reading file
This was caused by a spurious error being reported which this code silences.
Fixes#7532
See #3942
When f.opt.MaxAge == 0, f.db is never set, however several methods later assume
it is set and attempt to access it, causing an invalid memory address error.
This change fixes the issue in a few spots (there may still be others I haven't
yet encountered.)
Before this change, calling the `oauthutil.NewRenew` func may
cause goroutine leaks.
This change adds a `Shutdown` method to allow the caller to exit
the goroutine to avoid leaks.
