# blocklist_imports is a simple check against unwanted packages. The following
|
|
# packages are banned:
|
|
#
|
|
# * Package errors is replaced by our own package in the
|
|
# github.com/AdguardTeam/golibs module.
|
|
#
|
|
# * Packages log and github.com/AdguardTeam/golibs/log are replaced by
|
|
# stdlib's new package log/slog and AdGuard's new utilities package
|
|
# github.com/AdguardTeam/golibs/logutil/slogutil.
|
|
#
|
|
# * Package github.com/prometheus/client_golang/prometheus/promauto is not
|
|
# recommended, as it encourages reliance on global state.
|
|
#
|
|
# * Packages golang.org/x/exp/maps, golang.org/x/exp/slices, and
|
|
# golang.org/x/net/context have been moved into stdlib.
|
|
#
|
|
# * Package io/ioutil is soft-deprecated.
|
|
#
|
|
# * Package reflect is often an overkill, and for deep comparisons there are
|
|
# much better functions in module github.com/google/go-cmp. Which is
|
|
# already our indirect dependency and which may or may not enter the stdlib
|
|
# at some point.
|
|
#
|
|
# See https://github.com/golang/go/issues/45200.
|
|
#
|
|
# * Package sort is replaced by package slices.
|
|
#
|
|
# * Package unsafe is… unsafe.
|
|
#
|
|
# Currently, the only standard exception are files generated from protobuf
|
|
# schemas, which use package reflect. If your project needs more exceptions,
|
|
# add and document them.
|
|
#
|
|
# NOTE: Flag -H for grep is non-POSIX but all of Busybox, GNU, macOS, and
|
|
# OpenBSD support it.
|
|
#
|
|
# NOTE: Exclude the permission_windows.go, because it requires unsafe for the
|
|
# OS APIs.
