This ensures all user-installed gems persist across Workstation package upgrades. Changes: - GemForwarder sets GEM_HOME/GEM_PATH to user gem dir in Habitat mode - habitat_user_gem_dir helper returns version-specific path - habitat_env updated to include user gem dir in PATH/GEM_PATH - plan.sh wrapper resolves Ruby ABI version at runtime - plan.ps1 sets CHEF_GEM_HOME_ENABLED for Ruby-level handling - binstub_patch.rb includes user gem dir in GEM_PATH - plan.sh adds bundle config unset with to avoid build conflicts Signed-off-by: nitin sanghi --- binstub_patch.rb | 3 +- habitat/plan.ps1 | 5 + habitat/plan.sh | 19 ++- lib/chef-cli/command/gem.rb | 37 +++++- lib/chef-cli/helpers.rb | 17 ++- spec/unit/command/gem_spec.rb | 175 +++++++++++++++++++++++++++ spec/unit/command/shell_init_spec.rb | 13 +- spec/unit/helpers_spec.rb | 25 +++- 8 files changed, 272 insertions(+), 22 deletions(-) create mode 100644 spec/unit/command/gem_spec.rb diff --git a/binstub_patch.rb b/binstub_patch.rb index 00599425f..1ef6a1afd 100644 --- a/binstub_patch.rb +++ b/binstub_patch.rb @@ -1,4 +1,5 @@ unless ENV["APPBUNDLER_ALLOW_RVM"] ENV["APPBUNDLER_ALLOW_RVM"] = "true" - ENV["GEM_PATH"] = [File.expand_path(File.join(__dir__, "..", "vendor")), ENV["GEM_PATH"]].compact.join(File::PATH_SEPARATOR) + user_gem_home = File.expand_path(File.join("~", ".chef", "ruby", RbConfig::CONFIG["ruby_version"], "gems")) + ENV["GEM_PATH"] = [user_gem_home, File.expand_path(File.join(__dir__, "..", "vendor")), ENV["GEM_PATH"]].compact.join(File::PATH_SEPARATOR) end diff --git a/habitat/plan.ps1 b/habitat/plan.ps1 index bf92f0b74..73b1693e1 100644 --- a/habitat/plan.ps1 +++ b/habitat/plan.ps1 @@ -36,6 +36,11 @@ function Invoke-SetupEnvironment { Set-RuntimeEnv FORCE_FFI_YAJL "ext" Set-RuntimeEnv LANG "en_US.UTF-8" Set-RuntimeEnv LC_CTYPE "en_US.UTF-8" + + # Allow user-installed gems to persist across package upgrades. + # The actual GEM_HOME/GEM_PATH will be resolved at runtime to include + # ~/.chef/ruby//gems via the chef-cli Ruby code. + Set-RuntimeEnv CHEF_GEM_HOME_ENABLED "true" } function Invoke-Build { diff --git a/habitat/plan.sh b/habitat/plan.sh index fc42c5808..3e6523451 100644 --- a/habitat/plan.sh +++ b/habitat/plan.sh @@ -17,6 +17,11 @@ do_setup_environment() { set_runtime_env APPBUNDLER_ALLOW_RVM "true" # prevent appbundler from clearing out the carefully constructed runtime GEM_PATH set_runtime_env LANG "en_US.UTF-8" set_runtime_env LC_CTYPE "en_US.UTF-8" + + # Allow user-installed gems to persist across package upgrades. + # The actual GEM_HOME/GEM_PATH will be resolved at runtime via the wrapper + # script to include ~/.chef/ruby//gems. + set_runtime_env CHEF_GEM_HOME_ENABLED "true" } do_prepare() { @@ -43,6 +48,7 @@ do_build() { build_line "Setting GEM_PATH=$GEM_HOME" export GEM_PATH="$GEM_HOME" + bundle config unset with bundle config --local without integration deploy maintenance test development profile bundle config --local jobs 4 bundle config --local retry 5 @@ -89,10 +95,17 @@ do_install() { #!$(pkg_path_for core/bash)/bin/bash set -e -export PATH="$(pkg_path_for ${ruby_pkg})/bin:/sbin:/usr/sbin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:$pkg_prefix/vendor/bin:\$PATH" +# Determine Ruby version for user gem path +RUBY_ABI_VERSION=\$($(pkg_path_for ${ruby_pkg})/bin/ruby -e 'puts RbConfig::CONFIG["ruby_version"]') +USER_GEM_HOME="\${HOME}/.chef/ruby/\${RUBY_ABI_VERSION}/gems" + +# Create user gem directory if it does not exist +mkdir -p "\${USER_GEM_HOME}" + +export PATH="$(pkg_path_for ${ruby_pkg})/bin:/sbin:/usr/sbin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin:\${USER_GEM_HOME}/bin:$pkg_prefix/vendor/bin:\$PATH" export LD_LIBRARY_PATH="$(pkg_path_for core/libarchive)/lib:\$LD_LIBRARY_PATH" -export GEM_HOME="$pkg_prefix/vendor" -export GEM_PATH="$pkg_prefix/vendor" +export GEM_HOME="\${USER_GEM_HOME}" +export GEM_PATH="\${USER_GEM_HOME}:$pkg_prefix/vendor" exec $(pkg_path_for ${ruby_pkg})/bin/ruby $pkg_prefix/libexec/chef-cli "\$@" EOF diff --git a/lib/chef-cli/command/gem.rb b/lib/chef-cli/command/gem.rb index 0ddd6f344..0116d3e41 100644 --- a/lib/chef-cli/command/gem.rb +++ b/lib/chef-cli/command/gem.rb @@ -1,5 +1,4 @@ -# -# Copyright (c) 2019-2025 Progress Software Corporation and/or its subsidiaries or affiliates.
