[deb] Avoid `UTF-8` roundtrip for `{pre,post}-{inst,rm}` hooks (#1054)

This change allows the Debian package hooks to be arbitrary files (including
executable binary files), which failed with the following error before:

Bazel package building

Bazel rules for building tar, zip, deb, and rpm for packages.

For the latest version, see Releases (with WORKSPACE setup) / Documentation

Use rules-pkg-discuss@googlegroups.com for discussion.

CI:

Basic rules

Package building rules

pkg - Rules for building packages of various types.
examples - Cookbook examples for using the rules.

As of Bazel 4.x, Bazel uses this rule set for packaging its distribution. Bazel still contains a limited version of pkg_tar but its feature set is frozen. Any new capabilities will be added here.

WORKSPACE setup

Sample, but see releases for the current release.

To use pkg_rpm(), you must provide a copy of rpmbuild. You can use the system installed rpmbuild with this stanza.

load("@rules_pkg//toolchains/rpm:rpmbuild_configure.bzl", "find_system_rpmbuild")

find_system_rpmbuild(
    name = "rules_pkg_rpmbuild",
    verbose = False,
)

MODULE.bazel setup

bazel_dep(name = "rules_pkg", version = "0.0.10")

To use pkg_rpm(), you must provide a copy of rpmbuild. You can use the system installed rpmbuild with this stanza.

find_rpm = use_extension("//toolchains/rpm:rpmbuild_configure.bzl", "find_system_rpmbuild_bzlmod")
use_repo(find_rpm, "rules_pkg_rpmbuild")
register_toolchains("@rules_pkg_rpmbuild//:all")
