NOTE: This changes the Decider() function arguments. - From: - def my_decider(dependency, target, prev_ni): - To: - def my_decider(dependency, target, prev_ni, repo_node): - Where repo_node is the repository (or other) node to use to check if the node is out of date instead of dependency. - - - Enhanced --debug=explain output. Now the separate components of the dependency list are split up - as follows: - - scons: rebuilding `file3' because: - the dependency order changed: - ->Sources - Old:xxx New:zzz - Old:yyy New:yyy - Old:zzz New:xxx - ->Depends - ->Implicit - Old:/usr/bin/python New:/usr/bin/python - - - Changed: Pseudo-builders now inherit OverrideEnvironments. For - example when calling a pseudo-builder from another - pseudo-builder the override variables passed to the first - pseudo-builder call had to be explicitly passed on to the - internal pseudo-builder call. Now the second pseudo-builder call - will automatically inherit these override values. + - Update Command() function to accept target_scanner, source_factory, and target_factory arguments. + This makes Command act more like a one-off builder. + - Added support for "-imacros" to ParseFlags + - EXPERIMENTAL NEW FEATURE: Enable caching MSVC configuration + If SCONS_CACHE_MSVC_CONFIG shell environment variable is set, + SCons will cache the results of past calls to vcvarsall.bat to + a file; integrates with existing memoizing of such vars. + On vs2019 saves 5+ seconds per SCons invocation, which really + helps test suite runs. FIXES - - Fix Issue #3350 - SCons Exception EnvironmentError is conflicting with Python's EnvironmentError. - - Fix spurious rebuilds on second build for cases where builder has > 1 target and the source file - is generated. This was causing the > 1th target to not have it's implicit list cleared when the source - file was actually built, leaving an implicit list similar to follows for 2nd and higher target - ['/usr/bin/python', 'xxx', 'yyy', 'zzz'] - This was getting persisted to SConsign and on rebuild it would be corrected to be similar to this - ['zzz', 'yyy', 'xxx', '/usr/bin/python'] - Which would trigger a rebuild because the order changed. - The fix involved added logic to mark all shared targets as peers and then ensure they're implicit - list is all cleared together. - - Fix Issue #3349 - SCons Exception EnvironmentError is conflicting with Python's EnvironmentError. - Renamed to SConsEnvironmentError - - Fix Issue #3350 - mslink failing when too many objects. This is resolved by adding TEMPFILEARGJOIN variable - which specifies what character to join all the argements output into the tempfile. The default remains a space - when mslink, msvc, or mslib tools are loaded they change the TEMPFILEARGJOIN to be a line separator (\r\n on win32) - - Additional fix to issue #3135 - Also handle 'pure' and 'elemental' type bound procedures - - - Fix handling of Visual Studio Compilers to properly reject any unknown HOST_PLATFORM or TARGET_PLATFORM - - Enable LaTeX scanner to find more than one include per line - - under which they would be observed), or major code cleanups - - Thanks to CURLY, LARRY, and MOE for their contributions to this release. - Contributors are listed alphabetically by their last name. + - Fix suncxx tool (Oracle Studio compiler) when using Python 3. Previously would throw an exception. + Resolved by properly handling tool version string output as unicode. + - Resolved a race condition in multithreaded Windows builds with Python 2 + in the case where a child process is spawned while a Python action has a + file open. Original author: Ryan Beasley. + - Fix CheckFunc detection code for Visual 2019. Some functions + (e.g. memmove) were incorrectly recognized as not available. + - Fix stacktrace when using SCons with Python 3.5+ and SunOS/Solaris related tools. + - Latex: Avoid crash with UnicodeDecodeError on Python 3 when a Latex log file in + non-UTF-8 encoding (e.g. containing umlauts in Latin-1 encoding when + the fontenc package is included with \usepackage[T1]{fontenc}) is read. + - CmdStringHolder fix from issue #3428 + + IMPROVEMENTS + - Improved threading performance by ensuring NodeInfo is shared + across threads. Results in ~13% improvement for parallel builds + (-j# > 1) with many shared nodes. + - Improve performance of Entry.disambiguate() by making check for + most common case first, preventing unnecessary IO. + - Improved DAG walk performance by reducing unnecessary work when + there are no un-visited children. + + + PACKAGING + + - N/A + + DOCUMENTATION + + - N/A + + DEVELOPMENT + + - N/A + + +Thanks to the following developers for their contributions to this release. +git shortlog --no-merges -ns 3.1.1..HEAD + 59 Mats Wichmann + 21 William Deegan + 8 Edoardo Bezzeccheri + 5 Adam Gross + 5 maiphi + 4 Ivan Kravets + 4 Mathew Robinson + 2 Jakub Kulík + 2 Jacek Kuczera + 2 Rob Boehne + 2 Jason Kenny + 2 Tim Gates + 1 Jakub Kulik + 1 Theogen Ratkin + 1 jw0k + Copyright (c) 2001 - 2019 The SCons Foundation -src/RELEASE.txt e724ae812eb96f4858a132f5b8c769724744faf6 2019-07-21 00:04:47 bdeegan +src/RELEASE.txt bee7caf9defd6e108fc2998a2520ddb36a967691 2019-12-17 02:07:09 bdeegan |
