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names and years are hard to maintain and often out-of-date or plain wrong.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.
Run clang-tidy's modernize-use-override checker. This checker must have
issues in version 3.8. It has way too little matches. And it adds
override to destructors. Revert the changes on the destructors and
change override to CM_OVERRIDE.
Use clang-tidy's readability-simplify-boolean-expr checker.
After applying the fix-its, revise all changes *very* carefully.
Be aware of false positives and invalid changes.
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first). First
run `clang-format` with the config file:
---
SortIncludes: false
...
Commit the result temporarily. Then run `clang-format` again with:
---
SortIncludes: true
IncludeCategories:
- Regex: 'sys/types.h'
Priority: -1
...
Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:
$ git ls-files -z -- \
'*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
egrep -z -v '^Source/cm_sha2' |
egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
egrep -z -v '^Utilities/(KW|cm).*/' |
egrep -z -v '^Tests/Module/GenerateExportHeader' |
egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
xargs -0 clang-format -i
This selects source files that do not come from a third-party.

Remove use of cmXMLSafe from CTest when generating content that is later
handled by cmXMLWriter. This was broken by refactoring in the topic
merged by commit v3.3.0-rc1~22 (Merge topic 'ctest-xml-refactor',
2015-05-28).
In cmCTestMemCheckHandler::PostProcessBoundsCheckerTest return early
if the output file name is empty. We already do this in the similar
cmCTestMemCheckHandler::AppendMemTesterOutput method.
This showed up because scan-build noticed outputFull was basically
a constant. Logic should be output all valgrind output. Then output
regular test output until output limit is reached.
Since the Sanitizers write out one log file per process, a single
test might have more than one log file. This commit allows ctest
to read all of the log files found for a particual test.
Before this commit, you would have to run ctest -S mode to get
MemoryCheckType to work. This is because CMAKE_COMMAND was not set.
The fix is to use cmSystemTools::GetCMakeCommand instead.
This adds support for memory and leak sanitizers. This is built into
clang and gcc 4.8 and new compilers. It is activated with a -f switch
during compile.
This commit adds support for ThreadSanitizer to ctest. ThreadSanitizer
is part of the clang compiler and also gcc 4.8 and later. You have to
compile the code with special flags. Then your code gets the the
ThreadSanitizer ability built into it. To pass options to the
ThreadSanitizer you use an environment variable. This commit teaches
ctest to parse the output from ThreadSanitizer and send it to CDash.
For testing purposes CMake creates dummy memory checkers. The dummy checkers
are in the CMake build tree. Before this change when the path contained the
string valgrind, such as CMake-valgrind, all the checkers were thought to
be valgrind, and this caused tests to fail.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
The output file used for memory checker runs must be unique for every test run
in parallel, so simply make them unique for every test run. Simply use the test
index to avoid collisions.
The --workaround-gcc296-bugs has been part of the default Valgrind flags since
Valgrind support was added in commit 5b232ded15
(ENH: Add initial memory check support which works for Valgrind, 2003-12-15).
The Valgrind manpage says that this option should be avoided if not really
needed as it may cause real errors to get ignored. If someone uses a compiler
that really needs the flag this flag should be set by the user explicitely.
Most users will never set any flags and probably never notice that they use a
flag they shouldn't.
The memory checker command can't be quoted at this point, because previously it
has been tested that the given file exists, which will fail if the name is
quoted. The CTestTestMemcheckUnknown test aimed to test this case, has always
failed to do so and serves no useful purpose therefore.
If the checker was explicitely set with a "TypeCommand" variable (e.g.
ValgrindCommand) then we now just believe that this is valgrind, even if
nothing in the path matches "valgrind". Only when "MemoryCheckCommand" was used
we still scan the path to find out what checker we have.
The filename was escaped in cmCTestMemCheckHandler::InitializeMemoryChecking()
and again before it was written to output in
cmCTestRunTest::ComputeArguments().
Once someone uses e.g. a valgrind path with spaces this leads to double escaping
making the memory checker fail completely because of the invalid path.
Previous code was missing some matches in the output. This commit
fixes the regular expressions used for output matching to detect
numbers reported with commas in them, too.
