Many of these locals are wasteful, since they are always sized to the
biggest buffer required. This is the minimal and safe solution. Future
work will tune them to the correct size.
Remove the `basic_` prefix from valptridx<T>::basic_ptr, ::basic_idx,
and ::basic_ptridx. Since the public names are typedef aliases of these
classes, these class names appear frequently in debug information and
error messages. The `basic_` prefix is unnecessary. Remove it.
git grep -lz '\<basic_\(ptr\|ptridx\|idx\)\>' -- common/include/ | xargs -0 sed -i -e 's/\<basic_\(ptr\|ptridx\|idx\)\>/\1/g'
On Windows, the hook function blocks until the user dismisses the
message box. Print the message before opening the message box so that
it is available on the console, if one exists.
Early implementations of integer_sequence used a naive implementation
that required one level of template depth per additional integer in the
sequence. Rebirth uses a private alternate implementation named
make_tree_index_sequence that requires only log(N) steps for an
N-element index_sequence. Recent versions of gcc ship a log(N) version
of integer_sequence. Probe for that version and, if found, use it
instead of the private implementation, on the theory that the compiler
writers did at least as good a job as I did, and possibly better if they
were able to leverage compiler implementation details.
- Add wrappers for PHYSFS_read and its convenience functions. Poison
the memory before calling PHYSFS, so that any uninitialized bytes
(likely caused by a short read) are reported if the caller tries to
access the value anyway.
- Add SConstruct options to enable wrapping, so that users do not need
to enumerate the wrapped functions manually.
- Fix link failure when using LTO+wrappers.
d2x::segment has all members of d1x::segment, as well as two new members
exclusive to d2x::segment. Structure layout is such that d1x::segment
requires the same size allocation, and places anonymous pad members in
the locations that become named members in d2x::segment. Thus, reusing
d2x::segment for d1x::segment does not change the size of the structure
nor the offsets of any members used. This reuse may enable some
functions to be better shared by the dsx project.
Future work will introduce uses of d1x/d2x in the other game when the
types can be usefully shared. Extend the anti-nesting guards to cover
mistakes that might arise when referring to the namespaces by their
real name, rather than the alias name dsx.
`value` is generic and unclear. It is always meant to be used as an
index into the Station array, so rename it `station_idx` to show this.
Define and consistently use `station_none` to represent that no station
is assigned.
Using precompiled headers includes vers_id.h into
similar/main/newdemo.cpp. gcc-4.9 reports a conflict between vers_id.h
`extern const char g_descent_build_datetime[21]` and newdemo.cpp macro
generated `extern const char g_descent_build_datetime[]`. The size is
only needed in the definition, so remove it from the declaration to
align with the macro-generated extern.
Delete stub "compiler-type_traits.h" header. Redirect all uses to the
standard <type_traits> header.

All supported compilers have an acceptable <type_traits>. Commit
4cb3d46148 ("Move <type_traits> test to Cxx11RequiredFeature") made
<type_traits> support mandatory in August and no one has objected.
Remove the indirection and use namespace std directly for type_traits
members.
Early unification efforts missed this one because it was in gamemine.c
for Descent 1, but segment.c for Descent 2. Move it to gamemine.cpp for
both, so that it can be static for both games.
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const
Changes to common/include/valptridx.h and common/include/fwd-valptridx.h
