Deprecated functionality in EasyBuild v5.0

(for a full overview of changes in EasyBuild v5.0, see here)

Some functionality is being deprecated in EasyBuild v5.0, and will no longer be supported in EasyBuild v6.0:

If you trigger any deprecated functionality when using EasyBuild v5.0, a warning message will be printed.

parallel easyconfig parameter

Use of the parallel easyconfig parameter was deprecated because it's semantics are ambiguous, the max_parallel easyconfig parameter should be used instead.

run_cmd and run_cmd_qa functions

The run_cmd and run_cmd_qa functions have been deprecated, and are scheduled to be removed in EasyBuild v6.0.

You should migrate to the new run_shell_cmd function instead.

'source' step

'source' step was renamed to 'extract', affects skipsteps easyconfig parameter + --stop configuration option

(renamed to post_processing_step, more info soon)

make_module_req_guess method in EasyBlock class

(replaced with module_load_environment class attribute, more info soon)

  • run method has been replaced with install_extension
  • prerun method has been replaced with pre_install_extension
  • postrun method has been replaced with post_install_extension
  • run_async has been replaced with install_extension_async

Older checksum types

The following checksum types are deprecated and should no longer be used: md5, adler32, crc32, sha1, and size.

EnvironmentModulesC or EnvironmentModulesTcl modules tools

The use of the older Environment Modules versions is deprecated. This corresponds to setting the module tool in EasyBuild to either EnvironmentModulesC or EnvironmentModulesTcl.

Those using Environment Modules should use at least version 4.3 or newer.

GC3Pie as job backend

The use of the GC3Pie job backend is deprecated. Those generating jobs from EasyBuild should use one of the other available backends instead, such as Slurm or PBS Python.

COMPILER*_FLAGS attributes in Compiler class

In the Compiler class, the COMPILER*_FLAGS attributes were renamed to change FLAGS to OPTIONS. This change was made to make it clearer as to the function of these attributes.

Easyconfig parameter modextrapaths_append

The functionality of modextrapaths_append is now implemented in modextrapaths through its prepend option:

modextrapaths = {
    'ENV_VAR_NAME': {
        'paths': 'path/to/extra/subdir',
        'prepend': False,
    },
}

Easyconfig parameter allow_append_abs_path

The functionality of allow_append_abs_path is now implemented in modextrapaths, which now accepts absolute paths by default and the position of paths can be controlled through its prepend option:

modextrapaths = {
    'ENV_VAR_NAME': {
        'paths': '/absolute/path/to/extra/subdir',
        'prepend': False,
    },
}

Easyconfig parameter allow_prepend_abs_path

The functionality of allow_prepend_abs_path is now implemented in modextrapaths, which now accepts absolute paths by default:

modextrapaths = {
    'ENV_VAR_NAME': '/absolute/path/to/extra/subdir',
}
