• Remove deprecated createmodule.sh and createmodule.py tools as shell script to modulefile conversion is now achieved with the sh-to-mod sub-command.
• Remove mention of the init* sub-commands in module usage message to put focus on the collection handling sub-commands.
• Do not declare anymore the chdir, module, module-trace, module-verbosity, module-user and module-log commands under the modulerc Tcl interpreter as no-op commands. A clear error message is obtained if these commands are still used in modulerc files instead of silently ignoring them.
• Return by default an empty string rather _UNDEFINED_ on getenv modulefile command if passed environment variable is not defined.
• Align empty directory name error message obtained on use sub-command with message obtained when module or collection name is empty.
• Accept non-existent modulepath on use sub-command.
• Install: installation option --enable-auto-handling is set on by default which enables the automated module handling mode (see MODULES_AUTO_HANDLING).
• Install: installation option --enable-extended-default is set on by default which allows partial module version specification (see MODULES_EXTENDED_DEFAULT).
• Install: installation option --enable-advanced-version-spec is set on by default which activates the Advanced module version specifiers
• Install: installation option --enable-color is set on by default which enables the auto output color mode (see MODULES_COLOR).
• Install: installation option --with-icase is set to search by default to activate case insensitive match on search contexts (see MODULES_ICASE).
• Install: installation option --enable-new-features has been reset following major version change as all the options it implied are now enabled by default.
• Install: installation option --enable-set-shell-startup is set off by default but could be enabled once installed through the initrc configuration file.
• Install: installation option --with-initconf-in is set to etcdir by default to locate configuration files in the directory designated by the --etcdir option. Therefore the initialization configuration file is named initrc in this directory, and the modulepath-specific configuration file is named modulespath.
• Only look at configuration files found in the location designated by the --etcdir or --initdir option (depending on the value of --with-initconf-in option). Configuration files were previously searched in both locations.
• Install: remove installation option --enable-compat-version. Compatiblity version co-installation is discontinued. switchml shell function and MODULES_USE_COMPAT_VERSION are thus removed as well.
• Testsuite: introduce the non-regression quick test mode. When the QUICKTEST environment variable is set to 1, only the main tests from the non-regression testsuite are run. When first argument of the mt script is quick, tests are run in quick mode.
• Install: run non-regression testsuite in quick mode in RPM spec file.
• Rename the environment variables that are used by Modules to track loaded environment state (variables whose name starts with MODULES_LM). A __ prefix is added to the name of these variables to indicate that they are intended for internal use only.
• Rename the environment variables used to indirectly pass to modulecmd.tcl the value of variables set in quarantine (variables whose name finishes with _modquar). A __MODULES_QUAR_<VAR> prefix is applied to the name of these variables instead of the _modquar suffix to indicate they are intended for Modules internal use of only.
• Update Tcl requirement to version 8.5 as Tcl 8.4 is deprecated since a long time and this version is not available anymore on recent OS distributions. Update internal code of modulecmd.tcl to take benefit from the features brought by Tcl 8.5.
• Split source code in several Tcl files hosted in tcl directory. When building Modules, the Tcl files are concatenated to make the modulecmd.tcl script.
• Record auto-loaded tag of loaded modules in __MODULES_LMTAG environment variable rather set a specific entry for module in the __MODULES_LMNOTUASKED environment variable.
• Rename the environment variables used by the reference counting mechanism of path-like environment variables. A __MODULES_SHARE_<VAR> prefix is applied to the name of these variables instead of the _modshare suffix to clearly indicate they are intended for Modules internal use of only.
• Reference counting mechanism is not anymore applied to the Modules-specific path variables (like LOADEDMODULES). As a result no __MODULES_SHARE_<VAR> variable is set in user environment for these variables. Exception is made for MODULEPATH environment variable where the mechanism still applies.
• When an element is added to a path-like variable through the append-path or prepend-path modulefile commands, add this element to the associated reference counter variable (named __MODULES_SHARE_<VAR>) only when this element is added multiple times to the path-like variable. When an element is removed from a path-like variable, this element is removed from the reference counter variable when its counter is equal to 1.
• When the use and unuse module sub-commands are not called during a modulefile evaluation, the reference counter associated with each entry in MODULEPATH environment variable is ignored. In such context, a module use will not increase the reference counter of a path entry already defined and a module unuse will remove specified path whatever its reference counter value.
• When the append-path, prepend-path and remove-path module sub-commands are not called during a modulefile evaluation, the reference counter associated with each entry in targeted environment variable is ignored. In such context, a module append-path/prepend-path will not increase the reference counter of a path entry already defined and a module remove-path will remove specified path whatever its reference counter value.
• Fix unuse sub-command when sereval modulepaths are specified as a single argument (i.e., /path/to/dir1:/path/to/dir2). Enabled modulepaths were not correctly detected when specified this way.
• Doc: clarify that an already defined path is not added again or moved when passed to the use sub-command or the append-path/prepend-path modulefile commands. (fix issue #60)
• Change the refresh sub-command to evaluate all loaded modulefiles and re-apply the non-persistent environment changes they define (i.e., shell aliases and functions). With this change the refresh sub-command is restored to the behavior it had on Modules version 3.2.
• Evaluate the modulefile commands resulting from a source-sh command through the current modulefile Tcl interpreter in order to evaluate them according to the current modulefile evaluation mode.
• When initializing Modules, refresh the loaded modules in case some user environment is already configured. This is especially useful when starting a sub-shell session as it ensures that the loaded environment in parent shell is correctly inherited, as the refresh sub-command re-applies the non-persistent environment configuration (i.e., shell alias and function that are not exported to the sub-shell). (fix issue #86)
• Init: add example code in default initrc, the initialization script of Modules, to either restore user's default collection if it exists or load a predefined module list at the end of the initialization process.
• When initializing Modules, evaluate the initrc configuration file in addition to the the modulespath configuration file and not instead of this file. initrc is evaluated after modulespath file.
• When the installation option --enable-modulespath is set, the list of modulepath to enable by default is now only defined in the modulespath configuration file and not anymore in the initrc configuration file.
• No error is raised when evaluating in display mode a modulefile without a value specified for the variant it defines. This change helps to learn all the variant a modulefile defines. As a result, the unspecified variant is not instantiated in the ModuleVariant array variable. (fix issue #406)
• When running the unsetenv modulefile command on an unload evaluation, do not unset designated environment variable if no value to restore is provided.
• Fix unsetenv to distinguish between being called on a unload evaluation without a value to restore or with an empty string value to restore.
• Make system modulefile command available from a modulerc evaluation context whatever the underlying module evaluation mode.
• Make is-used modulefile command available from a modulerc evaluation context.
• Remove internal state tcl_version_lt85 as Tcl 8.5+ is now a requirement.
• Forbid use of module source<source> command in modulefile or in an initialization rc file, the source Tcl command should be used instead. source sub-command should only be called from the command-line.
• Report the modules loading and unloading during the module command initialization (i.e., during the evaluation of the initrc configuration file). These report messages are disabled when the verbosity configuration option is set to concise or silent.
• During a module restore or source, only report the module load and unload directly triggered by these sub-commands. Load and unload triggered by other modules are reported through the automated module handling messages of the main modules.
• Enforce use of the module magic cookie (i.e., #%Module) at the start of global or user rc files, initrc configuration file or any scriptfile passed for evaluation to the source sub-command. These files are not evaluated and an error is produced if the magic cookie is missing or if the optional version number placed after the cookie string is higher than the version of the modulecmd.tcl script in use.
• Doc: alphabetically sort installation option in INSTALL document.
• Update the --enable-quarantine-support installation option to control a quarantine_support configuration option. When this option is enabled, the autoinit sub-command produces the shell code for the module shell function definition with quarantine mechanism support. When disabled, code is generated without quarantine support.
• Install: installation option --enable-quarantine-support is set off by default.
• Introduce the MODULES_QUARANTINE_SUPPORT environment variable to control the quarantine_support configuration option once Modules is installed. To enable the quarantine mechanism, MODULES_QUARANTINE_SUPPORT should be set to 1 prior Modules initialization or quarantine_support configuration option should be set to 1 in the initrc configuration file.
• Quarantine mechanism code in the Modules shell initialization scripts is now always defined and mechanism always applies if some environment variables are defined in MODULES_RUN_QUARANTINE.
• Code in the modulecmd.tcl script to restore environment variables put in quarantine is now always generated and applies if the __MODULES_QUARANTINE_SET environment variable is set to 1. This variable is set by the Modules initialization script prior calling the autoinit sub-command or by the module shell function if it has been generated with quarantine support enabled.
• Install: installation option --enable-silent-shell-debug-support is set off by default.
• Code to silence shell debug properties in the Modules shell initialization scripts is now always defined and mechanism applies if MODULES_SILENT_SHELL_DEBUG environment variable is set to 1.
• Code to silence shell debug properties in the module shell function could now be enabled if MODULES_SILENT_SHELL_DEBUG is set to 1 prior Modules initialization or if the silent_shell_debug configuration option is set to 1 in the initrc configuration file.
• Doc: clarify TOC and title of MIGRATING document.
• Doc: extend description of Modules configuration steps of in INSTALL document.
• Doc: document initrc and modulespath configuration files in module(1) man page.
• Install: replace example.txt by INSTALL.txt guide in RPM.
• Doc/Install: rename diff_v3_v4 document into changes.
• Doc: reorganize changes document to let room to describe Modules 5 changes.
