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
now builds for me on Debian-7 Wheezy 64bit
unqualified member functions in dependent base classes not found anymore.
Need to qualify either the class or the instance.
...for the very specific situation when we want
to explore an existing data structure, and the
exploration assumes value semantics.
The workaround then is to use pointers as values.
...attempt to build it based on the monadic iterator primitives.
Only problem is: need to find out relation between nodes
after the fact. In the real usage situation, this
is not a problem, since we have a state object
there, which can track the relation as it is established
the buildsystem will now pick up and link
all test cases according to the layer, e.g.
backend tests will automatically be linked
against the backend + library solely.
This is kind of a workaround to avoid having to maintain two variants.
Explanation: between Boost 1.42 and 1.52 there was the transition to a
reworked version of the filesystem library, itroducing some breaking changes
The new version distinguishes much clearer between the native and the
generic representation of paths -- which becomes relevant when porting
to non-POXIX operating systems.
Actually the intention was to use the generic path representation in all
configuration; currently this distinction is moot, since we're caring
only for POSIX systems.
So the workaround is to use the fsys::path::string() function, which
is available in both versions, but changed meaning to yield the native
string. Later, when able to deprecate older Boost versions, we should
switch to generic_string()
Note: an alternative solution was found by Mike Fisher in 3b39f35
using the compiletime define BOOST_FILESYSTEM_VERSION=2

...to extract the syntetic ordering from
DefsRegistry and make that a responsibility
of the (internal) syntactic representation
of the query.
doesn't pass the compiler yet
effectively this joins the two existing lines
of "Query" classes into one systematic representation
Next step would be to move all mutation operations
over to the Query::Builder
time handling is part of the library, while this
convenience shortcut relies on the Advice system,
which resides in the application lib.
To allow this kind of symbolic acces to a grid
entity defined "elesewhere", client code needs
to be linked against liblumieracore.so
especially this allows to use the Advice system
or the query resolvers from within library facilities
to refer to other implementation level services by name
the rules-based configuration and query system
will be located within the core application,
while the concrete implementation facilities
are expected to reside within the session or
maybe also the GUI.
This is kind of a 'rochade' refactoring to resolve
circular library dependencies and confine the parts
dependant on the session and MObjects to the Proc-Layer
And while we're in the middle of chainsaw surgery,
we'll concentrate further query-based facilities
alongside the config-rules within the App core.
