Changelog for 66-tools

In 0.2.0.1

Overview

This is a bug fix release.

Bug Fixes

  • pam_userd: export DBUS_SESSION_BUS_ADDRESS into the login session (87cb9cf). The guardian builds that address for the scandir branch, but the session of the user never received it, so a D-Bus client started from the session was left to the fallback of its implementation. The module now exports the very address the guardian gives to the scandir, gated on the same runtime directory check as XDG_RUNTIME_DIR.
  • 66-olexec: suppress a compilation warning on the return value of dup() (e5e2283).
  • Fix the version comparison of the documentation deployment (7841edb).

In 0.2.0.0

  • Adapt to oblibs 0.4.0.0
  • Depends on lib66 0.9.0.0

Overview

This release makes 66-tools fully oblibs-native. The direct dependencies on skalibs and execline are both gone, the legacy configure/make build has been removed in favor of meson, and 66-ns has been rewritten with proper supervision under a pid namespace.

Breaking changes

  • The legacy configure and make build system has been removed. The project is now built exclusively with meson (1c01296). See INSTALL.md.
  • The skalibs dependency has been dropped entirely; oblibs is self-contained and does not depend on it (ff6bfbf).
  • The execline dependency has been dropped: execl-cmdline no longer links it (796df87). No binary links execline anymore.
  • 66-ns now needs lib66 at build time (1ab255e): it includes <66/config.h> for the compile-time paths. It links no symbol from it, so lib66 is not a runtime dependency of that binary.
  • lib66 is now a mandatory dependency of the project, and libpam becomes a new one: 66-userd, 66-userctl and pam_userd.so are built unconditionally.

New features

  • 66-userd, 66-userctl and pam_userd: session and user tracking for a 66 system, without D-Bus. A PAM module reports the opening and the closing of a login session to a daemon which, on the first login of a user, mounts the runtime directory of that user and starts their 66-scandir and enabled trees, and on the last logout stops them. 66-userctl is the query and power-action CLI. The module is installed but never wired into the PAM stack by the package: see pam_userd, that step is mandatory.

    When a scandir is already running for that user, a previous guardian died and left its own behind, the scandir@ module is still enabled, or one was started by hand — it is adopted rather than started a second time, and the enabled trees are brought up on it. Services already up are left running.

  • 66-ns: supervision under a pid namespace. When a pid namespace is requested, 66-ns runs as pid 1 and acts as a transparent proxy for the supervised daemon: it forwards the catchable control signals to the tracked main, follows the real daemon across a double-fork, mirrors its exit code back to the supervisor, and tears the namespace down once the service is gone. The new -p, --pidfile option makes supervision authoritative (4e8f4be, a38366d).

  • Long options are now available for every tool, e.g. -h, --help (92436f3, cdc900b). execl-toc is intentionally left short-only, as its options mirror mount(8).

Bug Fixes

  • execl-toc: detect a group name lookup failure that previously went unnoticed (4b4a0ba).
  • 66-dbus-launch: bind the socket behind an exclusive lock, so a concurrent launch on the same path gets a clean EBUSY instead of stealing the path from the running instance (3e4c272).
  • 66-dbus-launch: reject a notification file descriptor greater than INT_MAX (ca039f2).
  • 66-which: fix a leak of the realpath result (fa9db26).
  • 66-dbus-launch: fix a swapped io_read argument order (fa9db26).

Enhancements

  • Ported every tool from skalibs to the new oblibs interfaces (fa9db26).
  • 66-ns has been rewritten as a set of focused, modular translation units backed by oblibs and lib66 (1ab255e).
  • execl-cmdline reimplements el_semicolon/el_getstrict natively on oblibs (796df87).
  • 66-dbus-launch migrates its service hash table from uthash to the oblibs intrusive hash table (6866b5e).
  • Documentation and CI are aligned on the 66 project: lowdown HTML/man rules, a mkdocs stack and matching pipeline stages (dcaa800), and the build instructions are unified into a single INSTALL.md (7925ab1).

In 0.1.2.0

  • Adapt to oblibs 0.3.4.0

Overview

This is a bug fix and enhancement release.

Bug Fixes

  • Fixed type behavior and adapted to oblibs for hash.h file (0182864).
  • Suppressed compiler warning (0182864).
  • Fixed typos in documentation (0182864, a536fb9).

Enhancements

  • Switched to Meson build system for improved cross-platform support and efficiency (378e67f). Traditional configure and make remain functional during the transition but consider it as deprecated. See INSTALL_MESON.md for details.

In 0.1.1.0

  • Adapt to oblibs 0.3.1.0

New features
