In AUTORCC with verbose output write the rcc re-generation reason and
the rcc command as on single string to avoid message chopping in concurrent
builds.
This class is ultimately intended as a replacement for cmsys::Process.
It spawns a series of processes using libuv, piping the output of each
command into the next.
Note: input support has not yet been implemented because write
support has not yet been implemented on cmUVStreambuf.
Avoid leaving any members uninitialized after construction even if they
are later initialized before use by methods. This helps convince static
analysis tools that the members are not used uninitialized.
New features
------------
CMake's `AUTOMOC` and `AUTOUIC` now cache information extracted when parsing
source files in `CMakeFiles/<ORIGIN>_autogen.dir/ParseCache.txt`.
This leads to faster `<ORIGIN>_autogen` target rebuilds, because source files
will be parsed again only if they're newer than the `ParseCache.txt` file.
The parse cache will be recomputed if it is older than the CMake executable.
`AUTOMOC` and `AUTOUIC` now check if `moc` or `uic` output files are older
than the `moc` or `uic` executable. If an output file is older than the
compiler, it will be regenerated. Therefore if a new `moc` or `uic` version
is installed, all output files will be regenerated.
`AUTOMOC` and `AUTOUIC` error and warning messages are more detailed.
Internal changes
----------------
`moc` and `uic` output file names are not computed in the `_autogen`
target anymore but in `cmQtAutoGenInitializer`. This makes the available at
the configuration stage for improved dependency computations (to be done).
In `AutogenInfo.cmake`, equally sized lists for "source file names",
"source file flags" and "compiler output file names" are passed to the
`_autogen` target. This replaces the separate file lists for
`AUTOMOC` and `AUTOUIC`.
Files times are read from the file system only once by using `cmFileTime`
instances instead of `cmQtAutoGenerator::FileSystem::FileIsOlderThan` calls.
All calls to not thread safe file system functions are moved to non concurrent
fence jobs (see `cmWorkerPool::JobT::IsFence()`). This renders the
`cmQtAutoGenerator::FileSystem` wrapper class obsolete and it is removed.
Instead of composing a single large settings string that is fed to the
`cmCryptoHash`, now all setting sub strings are fed one by one to the
`cmCryptoHash` and the finalized result is stored.
The `std::mutex` in `cmQtAutoGenerator::Logger` is tagged `mutable` and most
`cmQtAutoGenerator::Logger` methods become `const`.
Outlook
-------
This patch provides the framework required to
- extract dependencies from `.ui` files in `AUTOUIC`.
These will help to address issue
#15420 "AUTOUIC: Track uic external inputs".
- generate adaptive `make` and `ninja` files in the `_autogen` target.
These will help to address issue
#16776 "AUTOUIC: Ninja needs two passes to correctly build Qt project".
- generate (possibly empty) `moc` and `uic` files for all headers instead of a
`mocs_compilation.cpp` file.
This will help to address issue
#17277 "AUTOMOC: Provide a option to allow AUTOMOC to compile individual "
"moc_x.cxx instead of including all in mocs_compilation.cxx"
When building for iOS, the compiled target is placed into a bundle.
If a single-configuration generator is used, like Makefiles or Ninja,
the try_compile FILE_COPY behavior fails to find the bundle, because
it only looks for the bundle inside a Debug subfolder (presumably
to support a multi-configuration generator like Xcode).
Consider looking for the bundle in the root try_compile folder, as
well as in the location specified by CMAKE_TRY_COMPILE_CONFIGURATION.
Closes: #19211
On macOS ranlib truncates the fractional part of the static achive
file modification time. If the archive and at least one contained
object file were created within the same second this will make look
the archive older than the object file. On subsequent ninja runs
this leads to re-achiving and updating dependent targets.
As a work-around we touch the archive after ranlib.
Closes: #19222
On non-Windows platforms libuv assumes that file descriptors 0-2 are
always used for standard pipes and never for anything else. Otherwise,
libuv may re-use one of these descriptors and then fail an assertion
when closing it. Similarly, On Windows platforms our ConsoleBuf
implementation assumes that the standard handles are always open.
If CMake is run with any standard pipes closed, open them with
`/dev/null` or `NUL` to satisfy these assumptions.

In commit a1ad0a699b (target_link_libraries: Allow use with targets in
other directories, 2018-09-07, v3.13.0-rc1~94^2) we accidentally broke
the logic that adds `$<LINK_ONLY:...>` to private dependencies of static
libraries in their `INTERFACE_LINK_LIBRARIES` in the case that the
dependency is added from outside the directory creating the library.
The check for a valid target name should apply to the original name
specified by the caller and not the encoded cross-directory reference.
Fixes: #19197
