Fix in extreme cases, when the job is executing finish(), the listener added by calling OnFinish() will never be executed.
This change should not cause compatibility issues, as consumers should not make assumptions about whether listeners will be run in a new goroutine
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
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.
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.
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.
This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

Some changes about test cases:
Because MiddlewareCORS will return early on OPTIONS request,
this middleware should only be used once at NewServer function.
Test cases should pass AllowOrigin config instead of adding
this middleware again.
A new test case was added to test CORS preflight request with
an authenticator. Preflight request should always return 200 OK
regardless of autentications.

In this commit we accidentally removed the global --rc flags.
0df7466d2b cmd/rcd: Fix command docs to include command specific prefix (#6675)
This re-instates them.
This change addresses two issues with commands that re-used
flags from common packages:
1) cobra.Command definitions did not include the command specific
prefix in doc strings.
2) Command specific flag prefixes were added after generating
command doc strings.
The BSD-style license that Go uses requires the license to be included
with the source distribution; so add it as LICENSE.wasmexec (to avoid
confusion with the other licenses in rclone) and note the location of
the license in wasm_exec.js itself.
Solves link error while running rclone's wasm version. Go's `walltime1` function was renamed to `walltime`. This commit updates wasm_exec.js with the new name.
The directory created by `T.TempDir` is automatically removed when the
test and all its subtests complete.

This patch adds rclone_http_status_code counter vector labeled by
* host,
* method,
* code.
It allows to see HTTP errors, backoffs etc.
The Metrics struct is designed for extensibility.
Adding new metrics is a matter of adding them to Metrics struct and including them in the response handling.
This feature has been discussed in the forum [1].
