Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
Clang Static Analyzer is so smart that it reports a defect when this
intended null-deref is encountered. Use sizeof instead which has no
runtime effects.
With CMAKE_C_COMPILER=clang and CMAKE_C_FLAGS='-Wall -Werror', this test
breaks with -Werror,-Wuninitialized. Fix this by getting rid of the
temporary variable.
There are many style errors in these files. This patch fixes only
the syntactical errors.
The script which ported these to rst tripped on some incorrectly
formatted blocks in the original input documentation. Use a new
script to find problematic code (and then fix them manually):
#!/usr/bin/env python
import os
rootDir = '.'
def checkFile(fname):
f = open(fname)
lines = f.readlines()
started = False
counter = 0
for l in lines:
if "#" in l:
started = True
elif started:
return
lin = l.find("(")
if lin != -1 and l.find(")", lin) == -1 and \
not "(To distribute this file outside of CMake, substitute the full" in l:
for lp in lines[counter+1:]:
if lp == "# ::\n":
print "\n\n######### " + fname + "\n\n"
print ''.join(lines[max(counter-2, 0):counter+6])
break
elif lp == "#\n" :
continue
break
counter += 1
for dirName, subdirList, fileList in os.walk(rootDir):
for fname in fileList:
checkFile(os.path.join(dirName, fname))
Previously if headers required to check if a struct has a member can be
compiled with C++ compiler only, the check would fail because the C
compiler fails. As a consequence, the result variable would be set to
false, even if the struct has that particular member.
Teach CHECK_STRUCT_HAS_MEMBER to accept a new optional argument LANGUAGE
that allows one to explicitly set the compiler to use. The new
signature is therefore:
CHECK_STRUCT_HAS_MEMBER (<struct> <member> <header> <variable>
[LANGUAGE <language>])
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
This adds copyright/license notification blocks CMake's non-find
modules. Most of the modules had no notices at all. Some had notices
referring to the BSD license already. This commit normalizes existing
notices and adds missing notices.
