SCons 4.9.0 Released
by Bill Deegan March 2, 2025

March 2, 2025

A new SCons release, 4.9.0, is now available on the SCons download page: https://scons.org/pages/download.html Here is a summary of the changes since 4.8.1: NOTE: Since SCons 4.9.0, Python 3.7.0 or above is required. CHANGED/ENHANCED EXISTING FUNCTIONALITY --------------------------------------- - Expose the `extra_libs` keyword argument in `CheckLibWithHeader` and 'CheckLib' - Removed Python 3.6 support. - Override environments, created when giving construction environment keyword arguments to Builder calls (or manually, through the undocumented Override method), were modified not to "leak" on item deletion. The item will now not be deleted from the base environment. - Added support for tracking beamer themes in the LaTeX scanner. - MSVS: msvs project files are always generated before the corresponding msvs solution files. This changes the behavior of clean for a project generated with auto_build_solution disabled and explicit solution generation: when the solution files are cleaned, the project files are also cleaned. The tests for vs 6.0-7.1 were updated accordingly. - MSVS: Add an optional keyword argument, auto_filter_projects, to MSVSSolution. Accepted values for auto_filter_projects are: - None [default]: raise an exception when solution file names or nodes are detected in the projects argument list. - True or evaluates True: automatically remove solution file names and nodes from the project argument list. - False or evaluates False: leave solution file names and nodes in the project argument list. An exception is not raised. Solution file names and/or nodes in the project argument list cause erroneous Project records to be produced in the generated solution file. As a convenience, a user may elect to ignore solution file names and nodes in the projects argument list rather than manually removing solution file names and nodes from the MSVSProject return values. - SCons C preprocessor: - Update the optional integer suffixes to include the z|Z and wb|WB suffixes. - Add support for binary integer constants. - Add support for octal integer constants. Previously, octal integers were evaluated as decimal integers. A literal zero (0) is treated as an octal number. - Change the method for attempted conversion of a define expansion value to an integer from a literal to a constant expression evaluation. - Add a tag to each CacheDir to let systems ignore backing it up (per https://bford.info/cachedir/). Update the way a CacheDir is created, since it now has to create two files. - The Dictionary method now has an as_dict flag. If true, Dictionary always returns a dict. The default remains to return different types depending on whether zero, one, or multiple construction - A Variables object now makes available a "defaulted" attribute, a list of variable names that were set in the environment with their values taken from the default in the variable description (if a variable was set to the same value as the default in one of the input sources, it is not included in this list). - If a build Variable is created with no aliases, the name of the Variable is no longer listed in its aliases. Internally, the name and aliases are considered together anyway so this should not have any effect except for being visible to custom help text formatters. FIXES ----- - PackageVariable now does what the documentation always said it does if the variable is used on the command line with one of the enabling string as the value: the variable's default value is produced (previously it always produced True in this case). - Temporary files created by TempFileMunge() are now cleaned up on scons exit, instead of at the time they're used. Fixes #4595. - AddOption now correctly adds short (single-character) options. Previously an added short option would always report as unknown, while long option names for the same option worked. Short options that take a value require the user to specify the value immediately following the option, with no spaces (e.g. -j5 and not -j 5). - Fix a problem with compilation_db component initialization - the entries for assembler files were not being set up correctly. - On Darwin, PermissionErrors are now handled while trying to access /etc/paths.d. This may occur if SCons is invoked in a sandboxed environment (such as Nix). - Added error handling when creating MSVC detection debug log file specified by SCONS_MSCOMMON_DEBUG. - MSVS: Modify select msvs test scripts to run on platforms not supported by the msvs/msvc tool implementation via a default host architecture for unsupported platforms. - MSVS: Fixed early loop exit in select msvs test scripts. Select msvs test scripts were being invoked for msvc version 8.0 only. Additional msvs tool and test changes due to the msvs test scripts being run for all msvc versions (i.e., minor test and tool issues went undetected). - MSVS: for variant build configurations, msvs solution files are generated in the source directory and a placeholder file is generated in the variant build directory. This mirrors the behavior of generated msvs project files. - MSVS: msvs project files are generated before the corresponding msvs solution file. User-specified project GUIDs should now be correctly written to the solution file. - SCons C preprocessor: Preserve literals that contain valid integer substring specifications. Previously, the integer suffix could be stripped from a symbol that contained an integer and suffix substring. - SCons C preprocessor: Update the optional integer suffixes to include support for the alternate orderings of unsigned with long or long long as defined in the c/cpp grammar. - SCons C preprocessor: Update the optional integer suffixes for case insensitive specifications as defined in the c/cpp grammar. - Fix nasm test for missing include file, cleanup. - Skip running a few validation tests if the user is root and the test is not designed to work for the root user. - Make sure unknown variables from a Variables file are recognized as such. Previously only unknowns from the command line were recognized (issue #4645). - Update ninja tool to use ninja.BIN_DIR to find pypi packaged ninja binary. python ninja package version 1.11.1.2 changed the location and previous logic no longer worked. - The (optional) C Conditional Scanner now does limited macro replacement on the contents of CPPDEFINES, to improve finding deps that are conditionally included. Previously replacement was only done on macro definitions found in the file being scanned. Only object-like macros are replaced (not function-like), and only on a whole-word basis; recursion is limited to five levels and does not error out if that limit is reached (issue #4523). - Minor modernization: make use of stat object's st_mode, st_mtime and other attributes rather than indexing into stat return. - Ninja's TEMPLATE rule pool changed from `local_pool` to `install_pool` hoping it will fix a race condition that can occurs when Ninja defers to SCons to build. - Renamed env.Help() & Help()'s argument `keep_local` to `local_only`, previously the documentation specified `local_only`, but the code and tests were using `keep_local`. The functionality more closely matches local only. NOTE: It doesn't seem like any code in the wild was using local_only as we'd not received any reports of such until PR #4606 from hedger. - Fix Issue #2281, AddPreAction() & AddPostAction() were being ignored if no action was specified when the Alias was initially created. - Handle case of "memoizer" as one member of a comma-separated --debug string - this was previously missed. IMPROVEMENTS ------------ - For consistency with the optparse "add_option" method, AddOption accepts an SConsOption object as a single argument (this failed previously). Calling AddOption with the full set of arguments (option names and attributes) to set up the option is still the recommended approach. - Add clang and clang++ to the default tool search orders for POSIX and Windows platforms. These will be searched for after gcc and g++, respectively. Does not affect explicitly requested tool lists. Note: on Windows, SCons currently only has builtin support for clang, not for clang-cl, the version of the frontend that uses cl.exe-compatible command line switches. DOCUMENTATION ------------- - Some manpage cleanup for the gettext and pdf/ps builders. - Some clarifications in the User Guide "Environments" chapter. - Clarify documentation of Repository() in manpage and user guide. - Many grammatical and spelling fixes in the documentation. - Update Clean and NoClean documentation. - Improved Variables documentation. - Update the User Guide Command() example which now shows a target name being created from '${SOURCE.base}.out' to use a valid special attribute and to explain what's being done in the example. DEVELOPMENT ----------- - Ruff/Mypy: Excluded items now synced. - Ruff: Linter includes new rules - `FA`, `UP006`, `UP007`, and `UP037` - to detect and upgrade legacy type-hint syntax. - Removed "SCons.Util.sctyping.py", as the functionality can now be substituted via top-level `from __future__ import annotations`. - Implemented type hints for Nodes. - Added TestSCons.NINJA_BINARY to TestSCons to centralize logic to find ninja binary - Refactored SCons.Tool.ninja -> SCons.Tool.ninja_tool, and added alias so env.Tool('ninja') will still work. This avoids conflicting with the pypi module ninja.
