The C++ standard library comes with perfectly fine implementations of
these functions, so there's no point in reimplementing them just for the
hell of it.
Using memset to initialize non-POD types doesn't work. Or rather, it may
work right now, but will fail when somebody adds a member that relies on
its constructor doing something (like for example any STL container).
Either way it's undefined behavior and needs to go. Furthermore, using
it to reinitialize an object also prevents any dtors from doing their
work when needed.
A new helper function InplaceReconstruct will take an object of nothrow-
default-constructible type, and call the dtor to properly clean up
before placement-new reconstructing the object in the same location.
This is still bad design, but unfortunately removing the Default/Clear
functions from every object currently using them is a herculean task.
C4Group::View is only used in the c4group command line tool, so the
right place for that code is inside the tool. Added two public constant
accessors to return the header data and entries.
Graphics are now pre-loaded and may then be accessed in random order. Reduces Objects.ocd load time from 20 seconds to 1 second for me.
Some ordering is still broken (e.g. material.ocg and player files).
C4Group::Open would sometimes overwrite more specific error messages or
not mention the problematic path. DirectoryIterator::Read also now mentions
more detail. Two superfluous messages were removed to make space.
As discussed in http://forum.openclonk.org/topic_show.pl?tid=2917, I
have merged all copyright notices into a single file and referenced that
merged file from each source file.
For the updated source files, the timeline has been split into three
parts:
1. Pre-RWD code (before 2001)
2. RWD code (2001 through 2009)
3. OpenClonk code (2009 and later)
All pre-RWD copyright notices have been left intact, as have RWD-era
copyright notices where the file did not have a RedWolf design copyright
notice but only individual author ones. All copyright notices of the
OpenClonk era have been replaced by a single notice ranging from the
first recorded year to the current year (2013). Mape code did not get a
OpenClonk Team copyright notice because it is somewhat separate from the
main OpenClonk codebase and has only been touched by Armin Burgmeier.
Fixes a bug with loading the shader file from scenario local Graphics.ocg on network clients. I think I also heard a few more sounds after the fix, so maybe they used random access into child groups too.
The CRC was basically only used to decide which files to include in update
groups, but calculated for every group and then stored in the file on disc.
And for some unknown reason, updates themself didn't produce the right
numbers in the file.
This means that c4groups with this change cannot reproduce groups written
by older c4groups and vice versa, but this isn't necessary for updates, and
reading is compatible both ways.
Except for the ways that C4Update fails to remove the CRCs.
This time with more manual checking and using git blame -M -C, so that
a few cases of copied code get a copyright notice corresponding to
their initial introduction.
