v1.9.0

Fixed

• Fixed error propagation in version resolution: Commands like phpvm use latest and phpvm install latest now correctly propagate failures from phpvm_resolve_version instead of silently swallowing errors.
• Fixed state consistency in switch_to_system_php: State file (active_version=system) is now only written AFTER the switch operation succeeds, preventing state lies when brew link operations fail.
• Fixed apt install/uninstall symmetry: Uninstall now removes php${version}-cli, php${version}-common, and php${version}-fpm packages symmetrically with what install creates.
• Fixed alias directory reliability: Alias directory creation is now required (not best-effort). If $PHPVM_DIR/alias cannot be created, phpvm fails with a clear error message.
• Fixed symlink robustness: update_current_symlink now uses command -v php to resolve the actual binary path, ensuring the symlink points to what the shell would execute.
• Fixed path traversal vulnerability in alias resolution: phpvm_resolve_version now validates alias names before file access, preventing path traversal attacks like ../../../etc/passwd.
• Fixed path traversal vulnerability in alias commands: phpvm_alias now validates alias names BEFORE any file path operations.
• Fixed trap restoration in sourced shells: phpvm_with_lock now explicitly clears traps with trap - SIGNAL when user had no existing trap, preventing phpvm's cleanup traps from being permanently installed in the user's shell session.
• Fixed init ordering for help/version commands: Moved command parsing before phpvm_init_or_die so phpvm help and phpvm version work without requiring package manager detection or system initialization.
• Fixed Linux version listing accuracy: Unified all Linux package managers (apt/dnf/yum/pacman) to use phpvm_linux_installed_versions which scans actual binaries, eliminating inaccurate package name listings like 8.2-cli or 8.2-fpm.
• Fixed system PHP symlink consistency: System switching now calls update_current_symlink to maintain consistent $PHPVM_DIR/current symlink behavior across all switching modes.
• Fixed alias security vulnerability: Reordered validation in phpvm_alias to validate version format before using it in file path checks, preventing potential path traversal attacks with malicious alias targets.
• Fixed yum installation strategy: Implemented proper Remi repository detection and naming conventions (php82-php-cli format), replacing incorrect yum install php8.2 approach that would always fail.
• Fixed lock PID staleness: Added explicit lock_pid="" reset at top of each phpvm_lock loop iteration to prevent stale PID values in error messages.
• Fixed unversioned PHP formula detection: Homebrew's unversioned php formula is now correctly identified before any unlinking operations, preventing false version matches from system PHP.
• Fixed phpvm which for unversioned formulas: Correctly returns path to unversioned PHP installed as php formula.
• Fixed apt package search: pkg_search_php() now explicitly checks for Candidate: (none) to avoid false positives from apt-cache policy.
• Fixed echo usage in input validation: Replaced echo "$var" | grep with printf '%s\n' "$var" | grep throughout to prevent interpretation of strings like -n, -e, backslash escapes.
• Fixed phpvm_which() failure propagation: Now properly propagates failures from phpvm_current using || return $?.
• Fixed shellcheck SC2221/SC2222 warnings: Simplified phpvm_is_sourced() case pattern to avoid overlapping matches.

Changed

• Introduced command_exists() helper: Replaced 40+ instances of command -v X > /dev/null 2>&1 with single reusable function for cleaner command availability checks.
• Introduced ensure_phpvm_dirs() function: Consolidated repeated mkdir -p $PHPVM_DIR/X patterns into centralized directory creation function.
• Introduced brew_link_php_unversioned() function: Extracted duplicate brew link php --force --overwrite logic with error handling into single reusable function.
• Introduced is_valid_version_format() function: Consolidated duplicate version regex validation pattern into single validation helper.
• Added brew_php_major_minor() helper: Reads version directly from $HOMEBREW_PREFIX/opt/php/bin/php instead of PATH-based php -r, eliminating conflicts with system PHP.
• Reordered version switching flow: Now resolves target formula, then unlinks all PHP, then links resolved formula, preventing "version check breaks after unlink" bugs.
• Improved Linux binary scanning: Broadened skip patterns to prevent accidentally executing PHP helper binaries (*fpm*, *cgi*, *dbg*, *ize*, *config*).
• Ubuntu/Debian apt packages: Changed from non-existent php8.2 to actual php8.2-cli format used by ondrej/sury PPA.
• Fedora/RHEL dnf packages: Implemented correct module stream approach instead of fictional versioned packages.
• Brew availability check: Changed from fragile brew search | grep to stable brew info <formula> API.
• Trap preservation in phpvm_with_lock(): Now saves and restores user's existing trap handlers instead of clobbering them.
• Stale lock detection and auto-cleanup: Lock mechanism now checks if lock holder PID is still running and automatically removes stale locks.

Added

• Interactive shell guard: Auto-switch from .phpvmrc now only runs in interactive shells using case $- in *i*) pattern.
• Test mode package manager bypass: Test mode now sets sandbox defaults without requiring actual brew/apt/dnf.

Internal

• Bash-only support documented: Added explicit notice that script requires bash (uses bashisms).
• Intentional symlink behavior clarified: Added comment explaining update_current_symlink() links to resolved php binary by design.
• Dnf module stream workflow: Added inline documentation about RHEL/Fedora module stream management.
• Version bump: Updated to v1.9.0.
• All tests passing: 51 BATS tests pass (added 4 security tests for path traversal protection).

• Fixed execution detection logic in phpvm_should_execute_main(): The original detection method incorrectly identified script execution as "sourcing" on macOS/zsh environments, causing the script to only load functions without executing the main command handler.
• Enhanced shell compatibility with argument-based detection: Added more reliable execution detection by checking for script arguments as the primary indicator, with the original return test maintained as fallback for POSIX shell compatibility.
• Improved detection layer ordering: Reorganized execution detection logic to prioritize more reliable methods (argument presence) over shell-specific tests that behave inconsistently across different environments.
