Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
We expect to handle all relevant statements and ignore those that we do
not understand. Warn if this process ever fails. Otherwise dependency
information may be silently left out.
The Intel 16 format starts with the 0x0A 0x00 sequence that we use to
skip past the timestamp. This occurrence appears to be a version
number. Skip the first byte to avoid matching the sequence early.
Ideally we should gain a better understanding of the format and avoid
depending on short sequences that are likely to appear early by
coincidence, but this approach will suffice for now.

Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first). First
run `clang-format` with the config file:
---
SortIncludes: false
...
Commit the result temporarily. Then run `clang-format` again with:
---
SortIncludes: true
IncludeCategories:
- Regex: 'sys/types.h'
Priority: -1
...
Commit the result temporarily. Start a new branch and cherry-pick the
second commit. Manually resolve conflicts to preserve indentation of
re-ordered includes. This cleans up the include ordering without
changing any other style.
Use the following command to run `clang-format`:
$ git ls-files -z -- \
'*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
egrep -z -v '^Source/cm_sha2' |
egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
egrep -z -v '^Utilities/(KW|cm).*/' |
egrep -z -v '^Tests/Module/GenerateExportHeader' |
egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
xargs -0 clang-format -i
This selects source files that do not come from a third-party.

Collect the original preprocessor definitions in a std::set<> so that
it can be copied directly by cmFortranParser's constructor instead of
making a copy on the stack.
The parser can be re-used outside cmDependsFortran or the cmDepends
class hierarchy so drop the "Depends" from its name:
rename 's/DependsFortran([A-Za-z0-9_])/Fortran$1/' Source/*.*
sed -i 's/DependsFortran\([A-Za-z0-9_]\)/Fortran\1/g' Source/*.*
sed -i 's/FortranInternals/DependsFortranInternals/g' Source/*.*
Also manually fix Source/CMakeLists.txt source file ordering.
In commit v3.3.0-rc1~352^2~3 (Genex: Allow COMPILE_LANGUAGE when
processing compile definitions, 2015-03-04) the name of the variable
used to pass preprocessor definitions to the Fortran dependency scanner
was changed to be per-language, but the actual dependency scanning code
was not updated accordingly. Update the code and add a test case.

Delay conversion of the path to object files (on the left-hand side
of dependencies) until just before they are written. Also do not
convert the format of paths written to the 'depend.internal' file.
This is consistent with the way the right-hand side of dependencies
are already handled.
From the GCC 4.9 release notes for Fortran:
https://gcc.gnu.org/gcc-4.9/changes.html
"Module files: The version of the module files (.mod) has been
incremented; additionally, module files are now compressed."
Teach cmDependsFortran::ModulesDiffer to look for the gzip magic numbers
at the beginning of the module file. If found, assume the module was
produced by gfortran >= 4.9. The modules do not appear to contain the
date as earlier versions did so we can compare the content directly
and do not actually need to decompress.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
This patch is heavily inspired by Michael Wild.
The interfaces cmDepends::Write and cmDepends::WriteDependencies where
extended to allow multiple dependees (sources) per depender (object).
cmDepends::Write first collect all dependencies into a std::set before
passing it to cmDepends::WriteDependencies.
cmDependsC::WriteDependencies also first collects all explicit and
implicit dependencies into a std::set and only then writes
depend.{internal,make}. The implementation of cmDependsFortran simply
loops over all sources and proceeds as before, whereas the cmDependsJava
implementation is as trivial as before.
This is for preventing exponential growth of depend.{internal,make} in
the next commit which fixes dependency-vector erasure in
cmDepends::CheckDependencies.

Makefile dependencies must be escaped using cmLocalGenerator::Convert
with the cmLocalGenerator::MAKEFILE option. This fixes Fortran module
dependencies with spaces in the path. We test the fix by adding a space
to one of the module paths in the Fortran test.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
The previous change to Source/cmDependsFortran.cxx while refactoring
implicit dependency scanning configuration rules completely broke
loading of the include file search path while scanning Fortran
dependencies. This adds the line that should have been added during the
previous change to load the include path correctly.
