Add 'deprecated' warning options type, to allow setting
CMAKE_WARN_DEPRECATED via the -W '-Wdeprecated' and
'-Wno-deprecated' options.
Add tests for new options and updated documentation.
Refactor the -Wdev and -Wno-dev options parser to use a generic -W
parser that follows the GCC pattern, excluding support for
-Werror=TYPE and -Wno-error=TYPE formats for now.
Explicitly enable author warnings by default, via the
cmake::GetSuppressDevWarnings method, which signals suppression
is turned off unless the CMake variables are set as required.
Add test cases for author and deprecated messages displayed by
default.
Make the message suppression more consistent, by adding a check
for the message related CMake variables in cmake::IssueMessage,
which allows callers of IssueMessage other than the message
command to behave as expected. Also added a check for
CMAKE_SUPPRESS_DEVELOPER_WARNINGS in the message command to
mirror the deprecated message type behaviour.
Added a 'force' flag to the cmake::IssueMessage method, to
make the message suppression consistent, when setting the
message related CMake variables directly in a CMake file.
Expand message command tests to cover the AUTHOR_WARNING message
type as well.
We enforce policy push/pop balance around any scope that pushes/pops a
snapshot. Therefore a snapshot may never reference entries of
PolicyStack that were created in nested scopes. Free storage of
short-lived policy stack entries when they are popped.
Add a method to increment an iterator (follow the "up" pointer) to the
previous level in the stack of scopes and free storage of the top of the
stack if possible. This will allow short-lived scopes to be created and
destroyed by matching Push/Pop pairs without accumulating storage.
Logically the method pushes a nested scope on top of a given scope
because the "up" pointer sequence forms a stack independent of any
other branches of the tree.
Everywhere we use cmMakefile::ScopePushPop to manage variable scopes
also expects policy scopes to be balanced. There is no place that we
use cmMakefile::PolicyPushPop without also using ScopePushPop. Relieve
PolicyPushPop of responsibility for policy scope balance checks by
moving it to ScopePushPop.
The PolicyPushPop constructor arguments and Quiet method were used to
pass non-default arguments to PushPolicy and PopSnapshot, but no clients
use them anymore.
The `PopPolicyBarrier` method is actually responsible for closing any
scope opened by creating a snapshot. Rename it to `PopSnapshot` and add
a comment explaining the purpose of the poilcy-scope-specific part of
the method.
Since commit v3.4.0-rc1~179^2~1 (cmState: Add a VariableScope snapshot
type, 2015-08-23) the snapshot stack may have a VariableScopeType entry.
Skip over these when constructing the call stack, just as we do for
policy scopes. Otherwise we report the command causing the variable
scope to be entered twice (e.g. find_package while loading a package
version file).
The property cannot be implemented on other generators because the
corresponding native build tools (VS IDE, Xcode, Ninja) all implement
their own `clean` operations that affect all outputs. Document this
limitation.
Change the Cobertura handler to look for an environment variable
called "COBERTURADIR" which contains the directory where the
coverage.xml file is found. If that variable doesn't exist,
continue to use the default of the binary directory.
Update the test to use an appropriate value in the environment
variables.
The change in commit f88533cc (CPackDMG: Add support for multilingual
SLAs, 2015-10-19) accidentally used CPACK_DMG_LANGUAGES in its
implementation instead of the intended CPACK_DMG_SLA_LANGUAGES added to
the documentation.
In commit v3.4.0-rc1~18^2 (Disable shared library support when compiler
links statically, 2015-09-30) we tried to detect when the compiler is
not capable of linking shared libraries (possibly due to flags in use).
However, the approach is not robust against flags like `-nostdlib`.
Revert it for now pending another solution to the original problem.
