* Merge branch 'policy-CMP0022-fixes' into policy-CMP0022-fixes-for-masterBrad King2013-11-0313-12/+50
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolve conflict in Source/cmTarget.cxx by integrating the changes to the internal copy constructor from both sides. Also resolve a logical conflict by dropping the special case for INTERFACE_LIBRARY targets. Since cmTarget::SetMakefile already forces CMP0022 to NEW for such targets we need no special handling. Resolve conflict in Source/cmTargetLinkLibrariesCommand.h by dropping the documentation change. We will make the same change in the new location of the same documentation in a separate commit. Resolve conflicts in Tests/RunCMake/CMP0022/CMP0022-WARN-empty-old-stderr.txt Tests/RunCMake/CMP0022/RunCMakeTest.cmake by taking the side from the 'policy-CMP0022-fixes' branch.
| * CMP0022: Warn about a given target at most onceBrad King2013-11-036-1/+16
| | | | | | | | | | | | | | | | | | | | | | Since cmTarget::ComputeLinkInterface is called separately for each "head" target that links a target, the warning we produce when CMP0022 is not set could be repeated. Add explicit logic to allow the warning to appear at most once. Multiple copies of the warning for the same target are almost always identical and therefore redundant. In the rare case that two copies of the warning are different, the second can appear in a future run after the first is fixed.
| * Do not export INTERFACE_LINK_LIBRARIES from non-linkable targetsBrad King2013-11-023-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When cmExportFileGenerator::SetImportLinkInterface exports the old LINK_INTERFACE_LIBRARIES property values it skips doing so for non-linkable targets because target->GetLinkInterface returns NULL for such targets. Since cmExportFileGenerator::PopulateInterfaceLinkLibrariesProperty looks at the INTERFACE_LINK_LIBRARIES property directly instead of using the computed link interface, teach it to skip exporting the property if target->IsLinkable returns false. Extend the RunCMake.CMP0022 test with a case covering this. Simply export an executable target that links to a library that is not exported.
| * CMP0022: Plain target_link_libraries must populate link interfaceBrad King2013-11-027-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CMP0022 NEW behavior is that the INTERFACE_LINK_LIBRARIES property exactly defines the link interface. The plain target_link_libraries signature says linking is transitive by default, so it should populate the property. Teach the target_link_libraries plain signature to populate the INTERFACE_LINK_LIBRARIES regardless of the CMP0022 setting. Refactor the cmTarget::ComputeLinkInterface checks that warn when the policy is not set to compare the new property to either the explicitly set old link interface properties or the link implementation fallback for all linkable target types, not just static libraries. This fixes a regression in 2.8.12.0 that caused target_link_libraries to not implement transitive linking in the plain signature once the policy CMP0022 is set to NEW.

This will allow CMake<LANG>Information.cmake and other logic to assume the full path to the compiler tool is available. The Makefile generators already rejected CMAKE_<LANG>_COMPILER values that did not name an existing compiler. Extend this error message to all generators, make it occur as early as possible, and improve the message with advice about how to set the compiler. If the full path to the compiler is not known, finish enabling languages with a fatal error so configuration does not continue. For now, allow the RC language compiler to not be a full path. Later we will need to detect the full path to "rc" under the VS IDE. Add a RunCMake.CompilerNotFound test to cover failure cases. Fix the RunCMake.CompilerChange test EmptyCompiler case to work when configuration does not continue past enable_language.

Other content like link flags should still be added to that property (wrapped in config-specific generator expressions), but not wrapped in LINK_ONLY. Otherwise undue warnings would be issued for the policy CMP0022. The LINK_ONLY expression only has an effect for actual target names anyway, so there is no logical deficit.

Drop the pair from the returned quoted argument token text. This will allow long lines inside quoted argument strings to be divided across multiple lines in the source file. It will also allow quoted argument text to start on the line after the opening quote. For example, the code: set(x "\ ...") sets variable "x" to the value "..." with no opening newline. Previously an odd number of backslashes at the end of a line inside a quoted argument would put a \-LF pair (or a \-CR pair) literally in the argument. Then the command-argument evaluator would complain that the \-escape sequence is invalid. Therefore this syntax is available to use without changing behavior of valid existing code. Teach the RunCMake.Syntax test to cover cases of quoted arguments with lines ending in \, \\, and \\\. Odd counts are continuations.

These start with two '[' separated by zero or more '=' characters e.g. "[[" or "[=[" or "[==[". They end with two ']' separated by the same number of '=' as the opening bracket. There is no nesting of brackets of the same level (number of '='). No escapes, variable expansion, or other processing is performed on the content between such brackets so they always represent exactly one argument. Also teach CMake to parse and ignore "long comment" syntax. A long comment starts with "#" immediately followed by an opening long bracket. It ends at the matching close long bracket. Teach the RunCMake.Syntax test to cover long bracket and long comment cases.
| * | | cmListFileLexer: Convert CRLF -> LF newlines explicitlyBrad King2013-10-174-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read input files in binary mode instead of text mode and convert CRLF newlines to LF newlines explicitly in our own buffer. This is necessary to read CMake source files with CRLF newlines on platforms whose C runtime libraries do not transform newlines in text mode. For example, a Cygwin or Linux binary may not transform CRLF -> LF in files read from a Windows filesystem. Perform the conversion ourselves to ensure that multi-line string literals in CMake source files have LF newlines everywhere.

| | | | | | | | | | | | | | | | | | | | | | | | Teach the lexer to read a UTF-8, UTF-16 BE/LE, or UTF-32 BE/LE Byte-Order-Mark from the start of a file if any is present. Report an error on files using UTF-16 or UTF-32 and accept a UTF-8 or missing BOM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach the lexer to treat a single letter as an identifier instead of an unquoted argument. Outside of a command invocation, the parser treats an identifier as a command name and an unquoted argument as an error. Inside of a command invocation, the parser treats an identifier as an unquoted argument. Therefore this change to the lexer will make what was previously an error case work with no other behavioral change.
