# This is the configuration for golangci-lint for the restic project.

# A sample config with all settings is here:

linters:
# only enable the linters listed below
disable-all: true
enable:
# make sure all errors returned by functions are handled
- errcheck
# find unused code
- deadcode
# show how code can be simplified
- gosimple
# # make sure code is formatted
- gofmt
# examine code and report suspicious constructs, such as Printf calls whose
# arguments do not align with the format string
- govet
# make sure names and comments are used according to the conventions
- golint
# detect when assignments to existing variables are not used
- ineffassign
# run static analysis and find errors
- staticcheck
# find unused variables, functions, structs, types, etc.
- unused
# find unused struct fields
- structcheck
# find unused global variables
- varcheck
# parse and typecheck code
- typecheck
issues:
# don't use the default exclude rules, this hides (among others) ignored
# errors from Close() calls
exclude-use-default: false
# list of things to not warn about
exclude:
# golint: do not warn about missing comments for exported stuff
- exported (function|method|var|type|const) `.*` should have comment or be unexported
# golint: ignore constants in all caps
- don't use ALL_CAPS in Go names; use CamelCase

locally as a pre-commit hook checks formatting before committing automatically,
just copy this script to `.git/hooks/pre-commit`.
The project is using the program
[`golangci-lint`](https://github.com/golangci/golangci-lint) to run a list of
linters and checkers. It will be run on the code when you submit a PR. In order
to check your code beforehand, you can run `golangci-lint run` manually.
Eventually, we will enable `golangci-lint` for the whole code base. For now,
you can ignore warnings printed for lines you did not modify, those will be
ignored by the CI.
For each pull request, several different systems run the integration tests on
Linux, macOS and Windows. We won't merge any code that does not pass all tests
for all systems, so when a tests fails, try to find out what's wrong and fix

Enhancement: Add more error checks
We've added a lot more error checks in places where errors were ignored before
(as hinted by the static analysis programm `errcheck` via `golangci-lint`).
