Running with default set of checks, except disabling the following
- appendAssign: append result not assigned to the same slice (diagnostics check, many false positives)
- captLocal: using capitalized names for local variables (style check, too opinionated)
- commentFormatting: not having a space between `//` and comment text (style check, too opinionated)
- exitAfterDefer: log.Fatalln will exit, and `defer func(){...}(...)` will not run (diagnostics check, to be revisited)
- ifElseChain: rewrite if-else to switch statement (style check, many occurrences and a bit opinionated, to be revisited)
- singleCaseSwitch: should rewrite switch statement to if statement (style check, many occurrences and a bit opinionated, to be revisited)

75dfdbf211 ci: revert revive settings back to fix lint
We accidentally disabled all the revive linters. Unfortunately setting
the rules clears the default set of rules so it is necessary to
mention all rules that we need.
golang.org/x/oauth2/jws is deprecated: this package is not intended for public use and
might be removed in the future. It exists for internal use only. Please switch to another
JWS package or copy this package into your own source tree.
github.com/golang-jwt/jwt/v4 seems to be a good alternative, and was already
an implicit dependency.
This changes crypt's use of sync.Pool: Instead of storing slices
it now stores pointers pointers fixed sized arrays.
This issue was reported by staticcheck:
SA6002 - Storing non-pointer values in sync.Pool allocates memory
A sync.Pool is used to avoid unnecessary allocations and reduce
the amount of work the garbage collector has to do.
When passing a value that is not a pointer to a function that accepts
an interface, the value needs to be placed on the heap, which means
an additional allocation. Slices are a common thing to put in sync.Pools,
and they're structs with 3 fields (length, capacity, and a pointer to
an array). In order to avoid the extra allocation, one should store
a pointer to the slice instead.
See: https://staticcheck.io/docs/checks#SA6002
The three linters deadcode, structcheck and varcheck we have been using are as of
gitlabci-lint version 1.49.0 (24 Aug 2022) marked as deprecated, and replaced by unused.
The linters staticcheck, gosimple, stylecheck and unused should combined correspond to
the checks performed by the stand-alone staticcheck tool, which is by default used for
linting in Visual Studio Code with the Go extension. We previously enabled the first
three, but skipped unused due to many reported issues.
See #6387 for more information.
These combined should correspond to the checks performed by the stand-alone
staticcheck tool, which is by default used for linting in Visual Studio Code
with the Go extension. One exception is the unused checks, which staticcheck
tool performs, but chose to not enabled here in rclone due to many reported
occurrences.
See #6387 for more information.
The upstream revive repo changed the default settings for this linter.
We use this through golangci-lint.
This change meant lots of errors appearing all at once. We should
probably fix these in due course, but for the time being this disables
those settings.
