Avoid duplicating the normal ctest output matching expression. Use
literal newlines instead of "\n" to improve readability. Integrate
matching of guard-malloc lines at the end of the output with expressions
matching tool output like lines for BullseyeCoverage.
Since commit 58e52416 (Warn about arguments not separated by whitespace,
2013-02-16) we warn about arguments not separated by spaces. Loosen the
warning to not complain about left parens not separated by spaces from
the preceding token. This is common in code like "if(NOT(X))".
Teach the RunCMake.Syntax test to cover cases of left parens not
separated by spaces and check that no warning appears.
Since commit 95f78e08 (OS X: Search for SDK based on deployment target,
2013-08-02) we select the default OS X SDK path to match the deployment
target. Fix this behavior in the case that the matching SDK does not
exist and fall back to the SDK for the current host OS X version.
Set the minimum required version of CMake high enough to avoid the
warning for CMAKE_LEGACY_CYGWIN_WIN32. The warning appears on stderr
and breaks the expected output matching.
The extendResult method expects a non-empty parameters vector, as
assured by the normal case. Avoid calling the method when the parser
finds an incomplete generator expression, but has already entered
the state of expecting to find parameters.

fc7c3b4 variable_watch: Store client data as pointers
The command itself is owned by the cmMakefile class, but the
cmVariableWatch which holds a pointer to the cmVariableWatchCommand via
the client_data for the callback outlives the cmMakefile class in the Qt
GUI. This means that when the cmMakefile is destroyed, the variable
watch is still in effect, but with a stale pointer.
To fix this, each callback is now a separate entity completely and
doesn't rely on the command which spawned it at all.
An example CMakeLists.txt which demonstrates the issue (only displayed
in cmake-gui, so no tests can be written for it):
set(var 0)
variable_watch(var)
When removing a watch on a variable, using the operator [] on the
internal map will create an empty watch if the variable doesn't have any
existing watches. Rather than creating this empty structure in the map,
return if there isn't a watch on the variable already.
If a callback has the same data as another call, we don't want to delete
the old callback. This is because if the client_data is the same, it
might get deleted causing the new client_data to be bogus. Now, AddWatch
will return true if it will use the watch, false otherwise. Callers
should check the return value to know whether client_data was adopted by
the watch or not.
The client data is arbitrary and the callback may be called an
unspecified number of times, so the cmVariableWatch must be the one to
delete the client data in the end (if it is needed at all).
In the future CMake will introduce Lua-style long bracket syntax.
Warn about unquoted arguments that in the future will be treated
as opening long brackets.
Teach the RunCMake.Syntax test to cover such cases and ensure that the
warning appears.
Teach the lexer to return tokens for whitespace. Teach the parser to
tolerate the space tokens where whitespace is allowed. Also teach the
parser to diagnose and warn about cases of quoted arguments followed
immediately by another argument. This was accidentally allowed
previously, so we only warn.
Update the RunCMake.Syntax test case StringNoSpace expected stderr to
include the warnings.
Replace the boolean value that indicates whether an argument is unquoted
or quoted with a generalized enumeration of possible argument types.
For now "Quoted" and "Unquoted" remain the only types.
If a line inside a string ends in a backslash count the following
newline character as a line increment. Add a test covering this case to
verify that subsequent line numbers are correct.
Test basic unquoted and quoted argument parsing cases including failure
on an unterminated string and an unterminated command invocation. Also
cover arguments not separated by any spaces, which is accidentally
allowed by the current parser.
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 Borland-built CTest binary has trouble running many instances of
itself in parallel, making the test unreliable. No particular recent
change appears to be the culprit and the failure is not reliably
reproducible. Just silence the failure for now by skipping the test.
