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.
|
| |
|
|
|
| |
Rename the internal enumeration value for converting paths destined
for use in Makefile rule syntax.

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.
|

|
| |
|

|
| |
Also use SystemTools::Fopen() instead of fopen().
This is to eventually support utf-8 filenames.

Some dependency-generators (such as cmDependsFortran) generate multiple
entries per depender, so erasing the dependency vector for each depender
found loses earlier dependencies.

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.

If the depender (e.g. foo.o) does not exist, also rescan dependencies if
one of the dependees (e.g. foo.cxx) is older than the already existing
depend.internal file, since this means it can be out of date.

Our Git commit hooks disallow modification or addition of lines with
trailing whitespace. Wipe out all remnants of trailing whitespace
everywhere except third-party code.
Run the following shell code:
git ls-files -z -- \
bootstrap doxygen.config '*.readme' \
'*.c' '*.cmake' '*.cpp' '*.cxx' \
'*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
'*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |

Declare variable only once at a scope appropriate for both uses.

Eliminate callers of cmMakefile::GetIncludeDirectories.
All callers of GetIncludeDirectories should go through the local generator
object.
Only the local generator calls cmTarget::GetIncludeDirectories directly.

The KWSys SystemTools::GetMaximumFilePathLength method is poorly
conceived and should not be used. The cmDepends code honors its own
MaxPath buffer size. Just hard-code it.

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.

Now only the dependencies for the file where the dependencies actually may
have changed are rescanned, before that this was done for all source files
even if only one source file had changed.
This reduces e.g. on my machine the time for scanning the dependencies
of kdelibs/khtml/ when only one file (khtml_global.cpp) has changed from
around 7.5 seconds to 1.2 seconds.
The tests succeed, it does what I expected it to do on kdelibs, and Brad
also reviewed the patch, so I think it should be ok.

When reading the depend.internal file, check only once for every depender
whether it exists, instead of repeatedly in a loop for each dependee. Within
that function it can only change of the depender is removed. This is taken
care of.
This reduces the number of access() calls in kdelibs/khtml from 180000 to
90000 (i.e. 50%), and reduces the time for that (without the actual
scanning) from 0.3 s to 0.21 s on my system.

- See issue #5809
- Keep information about all sources in the target until deps are written
- Create a fortran.internal file after scanning that lists modules provided
- Load fortran.internal files from linked targets to find modules
- Search the include path for external modules
- Create file-level deps on in-project module timestamps or external mods

to the dependency scanner to do proper path conversions. This allows the rules written into the depend.make files to use the same relative path conversion as those written into the build.make files. Several previous changes added more and more information for use by the dependency scanner and it was converging to having the full local generator anyway.
