Before this change, if any code called fs.Fatal(f) then it would stop
rclone as designed. However this is not appropriate when using the RC
API - we want the error returned to the user.
This change turns the fs.Fatal(f) call into a panic which is caught by
the RC API handler and returned to the user as a 500 error.
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.
This was caused by an incorrect handler URL which was passing the
debug/* commands to the debug/pprof handler by accident. This only
happened when using unix sockets.
Some libraries use `application/json; charset=utf-8` as their `Content-Type`, which is valid.
However we were not decoding the JSON body in that case, resulting in issues communicating with the rcserver.
This commit modernizes Go usage. This was done with:
go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...
Then files needed to be `go fmt`ed and a few comments needed to be
restored.
The modernizations include replacing
- if/else conditional assignment by a call to the built-in min or max functions added in go1.21
- sort.Slice(x, func(i, j int) bool) { return s[i] < s[j] } by a call to slices.Sort(s), added in go1.21
- interface{} by the 'any' type added in go1.18
- append([]T(nil), s...) by slices.Clone(s) or slices.Concat(s), added in go1.21
- loop around an m[k]=v map update by a call to one of the Collect, Copy, Clone, or Insert functions from the maps package, added in go1.21
- []byte(fmt.Sprintf...) by fmt.Appendf(nil, ...), added in go1.19
- append(s[:i], s[i+1]...) by slices.Delete(s, i, i+1), added in go1.21
- a 3-clause for i := 0; i < n; i++ {} loop by for i := range n {}, added in go1.22
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.
