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.
Refactor how cmCTestMemCheckHandler computes the memory tester command
line options to avoid encoding them in a single string just to parse
them again. The EscapeSpaces uses backslahes to escape spaces on UNIX
platforms, so replace other calls to it in CTest that are used to create
human-readable strings with simple double-quoting.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This class provides easy syntax to efficiently insert blocks of data
into XML documents with proper escapes. It replaces the old
cmCTest::MakeXMLSafe and cmSystemTools::MakeXMLSafe methods which
allocated extra memory instead of directly streaming the data.
This refactors generation of <Test> element headers and footers in
cmCTestTestHandler and re-uses it in cmCTestMemCheckHandler. The change
removes duplicate code and enables the new <Labels> element for MemCheck
results.
