| | | | | | | Comb out all code that supported earlier versions of Python. Most such code is in snippets of only a few lines and can be identified by having a Python version string in it. Such snippets add up; this combing pass probably got rid of over 500 lines of code.
* http://scons.tigris.org/issues/show_bug.cgi?id=2345Greg Noel2010-04-151-2/+1
| | | | | | | | | Fixes due to running the regression tests with the '-3' option to Python2.6, which causes the run-time to look for potential compatibility problems with Python 3.x. In some cases, all we can do is quiet the warning since we still support Python versions that can't use the newer idiom. In other cases, we fix the problem. This patch contains a mix of quieting and fixing, plus a little lint.

* http://scons.tigris.org/issues/show_bug.cgi?id=2329Greg Noel2010-03-271-2/+2
| | | | | | | | | | | | | | | Applied a number of idiomatic changes. Uses of the 'sort()' method were converted into calls of 'sorted()' when possible and the sorted() expression was inserted into a subsequent statement whenever that made sense. The statement 'while 1:' was changed to 'while True:'. Names from the 'types' module (e.g., 'types.FooType') were converted to the equivalent build-in type (e.g., 'foo'). Comparisons between types were changed to use 'isinstance()'.

Had a small effect on output formatting in many tests but no significant change to behavior. I reworked the patch a little to keep SCons exit status values the same as before; this patch could make it simpler to change them in some cases, e.g. exit with the errno of the failed action if desired. One nice side effect of this patch is that more scons errors print the node that caused the error now.

This involves failing each candidates along with their waiting parents. This is necessary because the waiting parents might be in the pending_children set() that is used by the taskmaster to determine if cycles exist in the dependency graph. Failure to do so leads to confusing error messages such as: scons: *** Found dependency cycle(s): Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/DynamicProperty.h (<SCons.Node.FS.File instance at 0x95d230c>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Fault/NotSupported.h (<SCons.Node.FS.File instance at 0x960634c>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Fault/InvalidRequest.h (<SCons.Node.FS.File instance at 0x95d2bac>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Fault/RequestCanceled.h (<SCons.Node.FS.File instance at 0x960648c>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Fault/InvalidType.h (<SCons.Node.FS.File instance at 0x95d2cec>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Core/InvalidProperty.h (<SCons.Node.FS.File instance at 0x9606d2c>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Fault/SecurityError.h (<SCons.Node.FS.File instance at 0x96065cc>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Core/PropertyCollector.h (<SCons.Node.FS.File instance at 0x9606e6c>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/Fault/InvalidArgument.h (<SCons.Node.FS.File instance at 0x95d2a6c>) Internal Error: no cycle found for node /bld/vmkernel-main/scons/build/vmodl/obj/generic/Vmodl/Vmomi/DynamicData.h (<SCons.Node.FS.File instance at 0x95d21cc>) Changes made: Job.py: ------ o Implemented an InterruptState object that allows the sharing of the interrupt state between the Jobs, the Serial/Parallel and the Worker thread object. This allows for somewhat faster interruption when Ctrl-C is pressed because the Worker thread will not start any new task, i.e. the ones siting in the request queue. Taskmaster.py: -------------- o Moved the code contained the function Task.fail_continue() to the function Taskmaster.will_not_build(). This function perform the clean-up for nodes that will never be built. This includes failing these nodes along with their waiting parents and removing them from the list of pending children. o Improved the taskmaster tracing so that the pending children ref counts of nodes is also printed. o When stopping the taskmaster, no_next_candidate() now calls will_not_build() repetitively to make sure that all candidate nodes that will never be build are properly cleaned-up. test/Parallel/multiple-parents.py --------------------------------- Improved the test to also exercise the following functionality: o Nodes with multiple targets (not just aliases as it was before). o SideEffect() o Interrupting the build.

Our scripts didn't test for direct importing of the submodules, so this broke when I implemented backwards comptability with a SCons/Options.py module, instead of a full SCons/Options/*.py package. This restores the SCons/Options/*.py package files with stub modules that provide backwards compatibility (by referring to the new SCons.Variables functions and classes) and allow for importing all of The test/Deprecated/Options/*Option.py scripts have had specific submodule imports added. To make sure this corresponding "feature" continues to work in the future, I'll be following this with another checkin that adds submodule imports for the SCons.Variables.*Variable modules. I ran this with the SCons/Options.py file in place, and also with a compiled SCons/Options.pyc file in place, to try to make sure it works regardless. We've seen issues on Debian where their packaging doesn't clean up old *.pyc files when a Python *.py module is removed.
