Various points in the game code call `hide_menus()`, then later use
`show_menus()` to reverse the effect. If the forcibly hidden window is
deleted before `show_menus()` is called, the attempt to show it would
write to freed memory. Add a hook to forget those windows when they are
deleted, so that `show_menus()` does not try to make them visible later.
`obj_get_signature()` examines all objects with a type other than
`OBJ_NONE` to find an unused signature.
`load_game_data()`->`read_object()` set an object's type before calling
`obj_get_signature()`, so `obj_get_signature()` would consider the
uninitialized signature of the newly loaded object for exclusion.
Reorder the initialization to compute the signature before the object is
given a type, then store the signature on the object after the poison
bytes (if any) are written.
Commit 1c8ad24 removed all reads of `wind`, but did not remove its
assignment or declaration. This breaks the build with gcc due to
-Wunused-but-set-variable.
Fixes: 1c8ad24da3 ("Check for window_event_result::deleted for ui_get_filename polling loop")
Commit 917f079 removed all reads of `wind`, but did not remove its
assignment or declaration. This breaks the build with gcc due to
-Wunused-but-set-variable.
Fixes: 917f079f02 ("Check for window_event_result::deleted in ui_dialog_do_gadgets")
This reverts commit 3c20c24ac0.
Rebirth no longer contains the Descent memory manager, but Rebirth still
has many traces of the paging support used in the DOS version. One of
the unfortunate and subtle traces of this support is that it allocates a
contiguous buffer for game data and loads many of the games bitmaps into
that buffer. The buffer is large enough for most workloads, but not
all. When the buffer is too small, it is discarded by
piggy_bitmap_page_out_all and rebuilt piecemeal to contain only what it
needs. Fixing this would be nice, but the memory ownership rules are
messy. The performance consequences of the legacy approach are not
sufficient to justify the effort to fix this properly. Instead, revert
to the legacy design.
This error was reported for gcc. Also set file extension correctly for 'enhanced' missions (though currently unused). Also some tidying up in response to feedback.
This removes an ambiguity when loading a saved game - we need to know the mission descent version **before** calling LoadLevel in state_restore_all_sub (a chicken and egg situation if we go down the fake dummy mission path). This also creates a fully playable mission (albeit simple).
To recognize getaddrinfo as supported, require that the AI_* flags
passed to it be usable:
- AI_NUMERICSERV must be defined as a number or be undefined
- If ipv6=1, then AI_V4MAPPED and AI_ALL must be defined as numbers
When getaddrinfo is used, raise _WIN32_WINNT from 0x501 to 0x600.
Otherwise, lower it to 0x500.
