The CopyFileIfDifferent, CopyFileAlways, CopyAFile and CopyADirectory
methods should always copy permissions. The special cases in which a
caller would pass copyPermissions=false should be handled at the call
site. The parameter needlessly complicates the interface and semantics
of these methods.
Use it from ExternalProject and the ExternalProject test's
CMakeLists file rather than having duplicate find_program calls.
Add logic so that we do not try to use *.cmd variants of git
programs when using the MSYS Makefiles generator. Should fix
the last remaining dashboard issue with the new ExternalProject
git support additions.
Also, correct minor problem regarding placement of the local git
repo during test execution. On clean builds, it was being placed
incorrectly because of the ../.. relative reference. Use an absolute
path to place the local git repo in the proper directory, and only
use the relative reference when referring to it.
If there is a .bat or .cmd file used as a custom command
then the Borland Makefiles generator (specifically) requires
using the "call " syntax before the name of the .bat or .cmd
file. This fix applies to all Makefile based generators where
WindowsShell is true.
On Windows 7 the file size reported by 'stat' on a new file sometimes
reports zero even though the real size is correct. This causes our
CopyFileAlways method to falsely detect copy failure. Work around the
problem by trusting the state of ofstream after writing the file.
Commit 0fafdb7e (Do not copy permissions of files when making the copy
in an install rule, 2008-12-18) added special behavior to KWSys file
copy methods for this special case. Use a local solution to avoid use
of the special behavior so it can be removed later.
Double quote executable names that may have spaces in them.
Do not run the new git portions of the test on machines that
have git < version 1.6.5 on them.
Add archives of these file types and add to the test
cases covered in the ExternalProject test.
Also add an "Example" directory in the Tests/ExternalProject
directory containing the canonical simplest example of
ExternalProject usage.
Improve FILE(DOWNLOAD ...):
- Add percent complete progress output to the FILE DOWNLOAD
command. This progress output is off by default to
preserve existing behavior. To turn it on, pass
SHOW_PROGRESS as an argument.
- Add EXPECTED_MD5 argument. Verify that the downloaded
file has the expected md5 sum after download is complete.
- Add documentation for SHOW_PROGRESS and EXPECTED_MD5.
When the destination file exists already and has the
expected md5 sum, then do not bother re-downloading
the file. ("Short circuit" return.)
Also, add a test that checks for the status output
indicating that the short circuit behavior is actually
occurring. Use a binary file for the test so that the
md5 sum is guaranteed to be the same on all platforms
regardless of "shifting text file line ending" issues.
Improve ExternalProject:
- Add argument URL_MD5.
- Add verify step that compares md5 sum of .tar.gz file
before extracting it.
- Add md5 check to download step, too, to prevent
unnecessary downloads.
- Emit a warning message when a file is not verified.
Indicate that the file may be corrupt or that no
checksum was specified.

Also, fix complaint that DOWNLOAD_COMMAND cannot contain arguments
consisting entirely of upper case letters. It validly does when,
for example, you construct a custom cvs command line and the module
name is all upper case, like VTK.
