In the November developer meeting, Christian and I agreed that
it's best to remove that offending LUID specifications altogether.
Those embedded LUIDs where one of the issues blocking the transition to C++11
this is rather a workaround.
The problem is a wraparound while calculating the common denominator in
Time rawTime (dirt + frames*F25);
Currently we're using boost_rational<long>, and long is only 32bit
on 32bit platforms. The workaround commited here just avoids
the calculation of the fractional value, and adds 64bit time values
instead. But the real solution would be to use a consistent
approach for dealing with frame counts and frame rates, all
based on 64bit values. See Ticket #939
This is a partial and preliminary fix; we had an occasional
numeric overflow on 32bit platforms in some tests.
The complete fix will be to introduce a typedef and then
rework the relevant APIs (which are preliminary anyway,
thus no urge right now)
our front-end for boost::format, the class lib::_Fmt
was lacking an reliable specialisation for long and ulong.
This is due to the notorious problem of these types being
of platform dependant size. As a fix, we're speclialising
explicitly for int16_t, int32_t and int64_t and avoid the
common names 'short', 'int' and 'long' alltogether.
And especially for non-64bit-platform (NONPORTABLE)
we add an explicit specialisation for long
The recommendation is to use the link flag --no-undefined
and to fed *all* dependencies to the respective link step.
This changeset enables this strict linking of dependencies.
It turned out that our dependencies were already sane
(with the sole exception of a direct dependency to X-Lib
in the XV viewer widget)
- upgrade the configuration to a current version
- provide a frontpage with cross-links to other documentation
- define a set of modules; relevant classes and files can be
added to these, to create a exploration path for new readers
- fix a lot of errors in documentation comments
- use a custom configuration for the documentation pages
- tweak the navigation, the sections and further arrangements
to make them stand out more prominently, some entity comments
where started with a line of starts. Unfortunately, doxygen
(and javadoc) only recogise comments which are started exactly
with /**
This caused quite some comments to be ignored by doxygen.
Credits to Hendrik Boom for spotting this problem!
A workaround is to end the line of stars with *//**
We don't need this ability and it pushes us into using a
central registry. This solution turned out to be problematic
when loading dynamic libraries (plug-ins).
Clang doesn't allow to declare a private nested class as friend.
This is unfortunate, but likely correct to the letter of the standard.
As a workaround, now we're creating the instances within a static
function of DependencyFactory -- in the end this improves readability
A second issue fixed with this changeset is the scope of the
marker function. Clang is right, this isn't ADL, thus an inline
friend definition is simply not visible outside the class.
lib::Depend<TY> works as drop-in replacement for lib::Singleton<TY>
This changeset removes the convoluted special cases like
SingletonSub and MockInjector.
Clang seems to evaluate the terms of a function call in another order
than GCC -- this uncovered re-entrance errors in some metaprogramming tests,
where we re-used a global formatter object in recursive instantiations.
Clang is more insistent when it comes to enforcing 'protected' visibility.
Since in this case the basic design can be considered sane and optimal, the
only (and obvious) solution is to nest the PIMPL into a default base class
for implementation; this mirrors the structure of the interface.
Compilation with Clang 3.0 (which is available in Debian/stable) fails,
mostly due to some scoping and naming inconsistencies which weren't detected
by GCC. At some instances, Clang seems to have problems to figure out a
perfectly valid type definition; these can be resolved by more explicit
typing (which is preferrable anyway)
using our util::_Fmt front-end helps to reduce the code size,
since all usages rely on a single inclusion of boost::format
including boost::format via header can cause quite some code bloat
NOTE: partial solution, still some further includes to reorganise
this draft fills in the structure how to get from an invocation
of the engine service to the starting of actual CalcStream instances.
Basically the EngineService implementation is repsonsile to
instruct the Segmentation to provide a suitable Dispatcher.
