|
|
# run tests that only work on PCs.

# unixOrPc - 1 means this is a UNIX or PC platform.
|
|
# macOrPc - 1 means this is a Mac or PC platform.
|
|
# nonPortable - 1 means this the tests are being running in
|
|
# the master Tcl/Tk development environment;
|
|
# Some tests are inherently non-portable because
|
|
# they depend on things like word length, file system
|
|
# configuration, window manager, etc. These tests
|
|
# are only run in the main Tcl development directory
|
|
# where the configuration is well known. The presence
|
|
# of the file "doAllTests" in this directory indicates
|
|
# that it is safe to run non-portable tests.
|
|
# tempNotPc - The inverse of pcOnly. This flag is used to
|
|
# temporarily disable a test.
|
|
# nonBlockFiles - 1 means this platform supports setting files into
|
|
# nonblocking mode.
|
|
# asyncPipeClose- 1 means this platform supports async flush and
|
|
# async close on a pipe.
|
|
# unixExecs - 1 means this machine has commands such as 'cat',
|
|
# 'echo' etc available.
