Modules 4.6.1 released

2020-11-14T20:30:00.001Z

Modules 4.6.1 is out. This release brings a significant performance improvement for the dynamic hiding/forbidding feature and several other fixes.

The changes introduced in this bugfix release are:

Lib: implement initStateClockSeconds as a Tcl command in libtclenvmodules to provide an optimized way to retrieve current Epoch time.
Lib: implement parseDateTimeArg as a Tcl command in libtclenvmodules to provide an optimized way to convert a datetime string into an Epoch time.
When full module specification is equal to @, raise an error as no module name is provided. (fix issue #362)
Optimize internal recording of hidden module and tag specification when parsing modulerc files in order to reduce the time taken to test if a given module is hidden or if a given tag applies to it.
Script: add the ability to select the benchmark test to perform on mb utility.
Doc: add Use new features without breaking old module command cookbook recipe
Doc: rework option description for module-hide and module-forbid commands in modulefile(4) document.
Doc: describe in diff_v3_v4 document that shell special characters like backticks are escaped when used in values starting Modules 4.0. (fix issue #365)
Doc: make the ENVIRONMENT section from modulefile(4) man page point to the ENVIRONMENT section of module(1) man page.
Fix clear sub-command to unset the MODULES_LMSOURCESH environment variable. (fix issue #367)
Correctly return on avail sub-command a symbolic version defined in a global RC file when specifically searched. (fix issue #368)
Fix module hiding resolution for symbolic versions defined in a global RC file when module-hide statements are set in the modulepath where the modulefiles targeted by these symbols are located. (fix issue #369)
When a module fails to unload during a purge sub-command, preserve loaded the modules it requires to keep environment consistent. (fix issue #370)
Doc: add Hide and forbid modules cookbook recipe.

Modules 4.5.3 released

2020-08-31T18:44:00.001Z

Version 4.5.3 of Modules has just been released. It provides fixes for the few issues recently spotted.

The changes introduced in this bugfix release are:

Install: take into account the --build, --host, --target, --enable-dependency-tracking and --disable-dependency-tracking configure options to transmit them to the configure scripts of Modules Tcl extension library and Modules compatibility version. (fix issue #354)
Install: ignore some regular options of an Autoconf configure script that are useless for this project but usually implied in build macros (like RPM %configure macro).
Install: ignore unsupported --enable-* and --with-* options on configure script rather raise an error and add support to define environment variable and build system type as configure script arguments to comply with GNU configuration recommendations.
Install: fix modulecmd pre-alternatives check in RPM spec file.
Install: use %make_build and %make_install macros in RPM spec file.
When module switch command is used in modulefile, do not state when processing it a conflict over switched-off module if its specification on the module switch command also matches switched-on module’s specification. Allow this way the replacement of any loaded version of a module for a specific one required by currently loading module. (fix issue #355)
Correctly report failed attempts to load module requirements expressed with advanced version specifiers. (fix issue #356)

Modules 4.4.1 released

2020-01-03T20:57:00.001Z

Modules version 4.4.1 is out and provides substantial performance improvements as well as fixes for the few issues spotted in the 4.4 serie.

The changes introduced in this bugfix release are:

Fix error and warning messages relative to dependency management to enclose dependency specification in single quotes to clearly distinguish specification from each other.
Skip output of module loading message if module is already loaded.
Doc: add demonstration material played at SC19 to promote the new features of Modules.
Contrib: add playdemo script to play recorded demonstration cast.
Doc: add a web anchor to each modulefile Tcl command, module sub-command and module environment variable documentation.
Install: update RPM spec file to enable build on el8.
Doc: fix RST syntax for bullet lists in design docs. (fix issue #306)
In case module avail query does not match a directory but only its contained elements (for instance module av mod/7 matches mod/7.1 and mod/7.2 but not mod/), fix query processing to correctly return latest or default element in case --latest or --default flags are set.
In case a module avail query performed in a no-indepth mode with --latest or --default flags either enabled or disabled, fix query processing to return directory elements if they are part of result.
When a module avail query performed in no-indepth mode targets a virtual module, fix result to filter-out the directory holding the virtual module from result.
Fix module avail --default queries when modulefile default version does not match query: select latest version from modulefiles matching query unless implicit_default configuration is disabled in which case no default version is returned.
Improve highlighting of module avail and whatis search result by coloring module names matching search query expressed with the advanced version specifiers. name@1,3 or name@1:3 queries now highlight name/1 and name/3 strings found in search result.
Contrib: add the mlprof script which wraps modulecmd.tcl to collect profiling information on its execution.
Contrib: adapt mb script to profile modulecmd.tcl run tests rather bench them when profile argument is passed to the script.
Improve overall performances of module names and versions comparison by introducing optimized procedures and caching in memory module search results.

Modules 4.3.1 released

2019-09-21T14:45:00.001Z

Modules version 4.3.1 is out. This new release provides fixes for the issues found recently on the 4.3 serie.

The changes introduced in this bugfix release are:

Contrib: add mb script to bench Modules versions.
Correct modulecmd.tcl script startup to correctly report error in case Tcl extension library fails to load. (fix issue #284)
Install: fix typo on CFLAGS definition in lib/Makefile. (fix issue #287 with contribution from Felix Neumärker)
Remove useless code in Modules Tcl extension library
Make URLs in README correctly rendered in HTML. (contribution from Per Persson)
Doc: clarify modulefile evaluation modes in modulefile.4 man page. (fix issue #289)
When looking at the closest match among loaded modules when switching module with just a single module argument specified, load the information on the currently set environment to get the alternative names of loaded modules prior to look at closest module match. (fix issue #290)
Doc: describe the way to determine the site-specific configuration script location in cookbook recipes implying the installation of such a file. (fix issue #266)
Doc: add Log module command recipe to cookbook. (fix issue #283)
Doc: add Expose procedures and variables to modulefiles recipe to cookbook.
Doc: add Make defined modulepaths persist over sudo recipe to cookbook.
Doc: add Ensure user fully qualify the modules they use recipe to cookbook.
Introduce the wa_277 configuration option to workaround an issue with Tcsh history mechanism. Default module alias definition for Tcsh hits an issue with shell history mechanism: erroneous history entries are recorded each time the module command is called. When wa_277 option is enabled (which sets the MODULES_WA_277 environment variable to 1), an alternative module alias is defined which fixes the history mechanism issue. However the alternative definition of the module alias weakens shell evaluation of the code produced by modulefiles. Characters with special meaning for Tcsh shell (like { and }) may not be used anymore in shell alias definition elsewhere the evaluation of the code produced by modulefiles will return a syntax error. (fix issue #277)
Doc: add Tips for Code Reuse in Modulefiles recipe to cookbook. (contribution from Tom Payerle)
Fix the whatis and paths sub-command results for module symbolic versions targeting a directory when implicit_default configuration option is disabled. No error is returned and same result is now obtained whether the symbolic name or its target is used as argument for those two sub-commands. (fix issue #294)
Fix the whatis and paths sub-command results for module aliases targeting a directory when implicit_default configuration option is disabled. No error is returned and same result is now obtained whether the alias name or its target is used as argument for those two sub-commands. (fix issue #295)
Rework all the ternary operator expressions in modulecmd.tcl that may result in a nan value (whatever the case used to write this string) as the expr Tcl command raises an error when it returns such a value, which breaks Modules as soon as a modulefile, an alias or a symbolic version is named nan. (fix issue #296)
