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.
bf5a5bc bootstrap: Do not suppress CMAKE_OSX_SYSROOT if CFLAGS have -isysroot (#14324)
95f78e0 OS X: Search for SDK based on deployment target (#14324)
Revert commit a1c032b9 (bootstrap: Suppress CMAKE_OSX_SYSROOT if CFLAGS
have -isysroot, 2012-09-21). If MACOSX_DEPLOYMENT_TARGET is set then
CMAKE_OSX_DEPLOYMENT_TARGET will be set and Darwin.cmake will complain
if no CMAKE_OSX_SYSROOT is set. Just allow both -isysroot flags to
appear. The one generated by CMAKE_OSX_SYSROOT appears after and
overrides the one from CFLAGS/CXXFLAGS.
When available, use CMAKE_OSX_DEPLOYMENT_TARGET instead of the host OS X
version to select the default SDK. This makes sense because one should
use the SDK matching the deployment target.

* The ALIAS name must match a validity regex.
* Executables and libraries may be aliased.
* An ALIAS acts immutable. It can not be used as the lhs
of target_link_libraries or other commands.
* An ALIAS can be used with add_custom_command, add_custom_target,
and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET
target property.
* An ALIAS does not appear in the generated buildsystem. It
is kept separate from cmMakefile::Targets for that reason.
* A target may have multiple aliases.
* An ALIAS target may not itself have an alias.
* An IMPORTED target may not have an alias.
* An ALIAS may not be exported or imported.
Fix generation of the AdditionalIncludeDirectories element content to
escape for XML syntax. We already escape content of other elements,
this one was simply missing by accident.
Use the WIN32_EXECUTABLE target property only to set the SubSystem build
attribute default. When user-specified flags are later parsed they may
then override it.
