CHANGELOG

Unreleased - Unreleased

4.3 - Pending

  • fix boost_thread tool to cache libs after first configure check
  • try to optimize how added methods are called to improve speed and debug tracing
  • use a global cache for pkg-config results, rather than per-Environment, presuming that all Environments in the same build will want to use the same settings for pkg-config dependencies
  • the deprecated file-backed-store for VariableCache has been removed, and now VariableCache works to cache variables globally, especially for the Qt tool
  • eol_scons can now be installed as a python package from source, in particular to create a scons build environment with pipenv that does not require a site_scons directory. See README.md.
  • relicense as MIT, update copyright info everywhere
  • make tests more robust on platforms with different package installations
  • prevent build_rpms from listing debug packages when disabled
  • fix staticlink.py tool when LIBPATH is not set: fixes error message NoneType object is not subscriptable trying to evaluate ${_replace_static_libraries(__env__)}
  • many obsolete and (presumed) unused tools have been removed
  • gcc.py tool: Sanitized output no longer needs to be translated, so AsanFilter() has been removed. See gcc.py for details.
  • testing.py tool: simplify SpawnerLogger and LogAction and make their arguments more consistent, but the changes are not backwards compatible and could change the console output. SpawnerLogger is now in its own module, eol_scons.spawner, and will accumulate all output when multiple actions are spawned by it.
  • refactor testing to use less shell script and more pytest
  • eol_scons_tool.py is now in its own site_tools directory

4.2.5 - 2023-12-13

  • git clean copied source directories before archiving them
  • fix build_rpm.sh to work when SConstruct is not in the top directory
  • add errors to buildmode to add -Werror flag
  • skip netcdf configure checks if pkg-config succeeds
  • cache Qt5 check rather than repeating it over and over
  • remove support for xerces-c 2.7
  • fix key error in nidas tool when LIBS not set

4.2.4 - 2023-09-02

  • canfestival support for API-only when python2 not available
  • QtUiPlugin now a recognized Qt5 tool.
  • Fixes for Qt and other tools on Ubuntu.
  • Changes in library discovery on Darwin.
  • Use PrintProgress for kmake messages so they can be suppressed with -Q.

4.2.3 - 2022-12-15

  • Keep build_rpm.sh working with spec files which use %setup -n <pkgname>.

4.2.2 - 2022-12-10

  • build_rpm.sh removes scons artifacts left over from a source copy or from the versionfiles target.
  • Debian packaging cleans compiled python and now installs the python package into the new location site_scons/eol_scons/eol_scons.
  • build_rpm.sh now has a test method to stage the source archive from a hard linked copy of the source repo instead of a clone. The source archive directory now has the conventional name {name}-{version}, so %setup macros no longer need the -n option.

4.2.1 - 2022-08-30

Fixed

  • In the Install() method which adds the automatic install alias, restore the resolution of the destination as a directory node before passing the destination along as string path. This forces variables to be interpolated when the builder is created, since some projects have relied on that.

Added

  • build_rpm.sh can create snapshot packages from untagged source using the commit hash as the version identifier. It bumps a copy of the spec file to a new version with the commit hash embedded, then the rest of the rpm build works as before. In particular the specific source version to be packaged is extracted from the version in the spec file. The spec changelog is technically not quite correct because it only contains a single new entry for the snapshot being created, it does not mention if there were any snapshots prior to it.

    Example:

    scons build_rpm scripts/eol_scons.spec snapshot

    The primary purpose is to test packaging for the latest commit without requiring a tag, but it could also allow projects to release rolling package snapshots if desired, since the generated package versions should order correctly. The packages are still only built from clean source checkouts.

4.2 - 2022-08-26

Added

  • The eol_scons source now has its own SConstruct for installing files to a directory specified by the PREFIX variable.

  • Scripts can now be shared and executed through the eol_scons package. Call eol_scons.RunScripts() to look for known script names on the command line, and if found, execute the script with any succeeding arguments. So far the only script is build_rpm. New scripts can be added easily, but they cannot require single-hyphen arguments, since those will be handled by scons. Scripts can use words or double-hyphen options. Example:

    $ scons -Q build_rpm scripts/eol_scons.spec rpms
/home/granger/rpmbuild_piglet/SRPMS/eol_scons-4.2~alpha2-1.fc35.src.rpm
/home/granger/rpmbuild_piglet/RPMS/noarch/eol_scons-4.2~alpha2-1.fc35.noarch.rpm

  • Help option -h --list-installs prints all targets in FindInstalledFiles().

  • Some messages printed by eol_scons, especially the initial boilerplate about loading configs, can now be suppressed with the SCons -Q (no_progress) option. SConscript files and tools can call the PrintProgress() method to print messages which should be suppressed by -Q.

Tool changes: gitinfo

  • Add gitinfo variable. When set to off, the gitinfo tool will try to load repo version info from a generated header instead of running git tools. This allows builds in source archives to use the repo version info, like for RPM packages.
  • Add gitdump target. For each directory where the gitinfo tool collects repo info, there is a target which prints the repo info. The target must be named on the command-line, like scons ./gitdump.
  • All gitinfo targets are added to a versionfiles alias, so generic scripts can generate all versioned output with scons versionfiles. There is also a no-op for the versionfiles alias, so scons versionfiles does not cause an error on projects which do not use gitinfo.

Changed

  • The eol_scons override of the Install() method can be disabled by calling eol_scons.EnableInstallAlias(False). It still defaults to enabled, but someday could be deprecated. This allows projects to choose different install aliases, like install and install.root and install.doc. There was also a change to allow the Install() override to work with the standard SCons option --install-sandbox.
  • Consolidate the buildmode settings into the single tool rather than providing separate tools for warnings, debug, and so on. This fixes a problem with SCons 4.4 where a python built-in module actually tries to import warnings.

Deprecated

  • eol_scons should now be installed as a subdirectory of site_scons. Prior to this, the eol_scons repository was typically cloned into ~/.scons and named site_scons, or else it was added to a project as a git submodule named site_scons. This practice interferes with adding other SCons extensions under the site_scons directory, and it is confusing that the repository is cloned with a different name. Now the site_scons directory must be created first, either as part of the project or in ~/.scons, then the eol_scons repository can be cloned into that directory with the name eol_scons. The new __init__.py file in the top directory takes care of adding the eol_scons/eol_scons directory to the path of the eol_scons package. Importing eol_scons using the old scheme prints a deprecation message.
  • eol_scons now requires Python 3.6. SCons 4.0 requires Python 3.5, SCons 4.4 requires Python 3.6, so eol_scons is following suit. The biggest known issue with this is that on RHEL7 the default python and scons is still python 2.7. There is a scons package based on python3, python36-scons, but it must be invoked as scons-3. The RPM spec has been updated to force byte compiling with python3 with an install dependency on scons-python3.

Removed

  • Remove runtime ld path (-R link option) in many places, partly to facilitate MacOS builds.

4.1 - 2021-01-25

  • Refactor for Qt5 modules, providing tools named after the module which apply that module for the project Qt version.
  • In prefixoptions tool, make sure optional extra search paths are always added last to CPPPATH and LIBPATH.
  • Port to SCons 4.1, removing use of SCons.Warnings.Warning.
  • Add jsoncpp tool.

3.0 - 2017-12-21

  • Port to SCons 3.0 and python 3.

2.9 - 2017-12-18

  • last tagged release before scons 3.0 port

2.0 - 2015-10-05

  • first tagged release
