If !defined(DXX_HAVE_CXX_BUILTIN_FILE_LINE), the default value is
omitted, but the comma between values is still required. The comma was
incorrectly guarded, so it was present only when a default value was
set.

Fixes: 544fc0f893 ("Add support for increased precision of gamelog timestamps")
- Enable display of subsecond (Linux: microseconds; Windows:
milliseconds) precision on gamelog timestamps.
- Add disabled support for YYYY-MM-DD leaders on gamelog timestamps.
Activate it by defining DXX_CONSOLE_TIME_FORMAT_YMD to true.
- Add disabled support for capturing caller __FILE__, __LINE__ in calls
to con_printf, con_puts. Activate it by defining
DXX_CONSOLE_SHOW_FILE_LINE to true. If captured, write those to
gamelog after the timestamp and before the text. This feature (and
only this feature) requires that DXX_HAVE_CXX_BUILTIN_FILE_LINE be
defined, which is conditional on if the compiler has __builtin_FILE()
and __builtin_LINE(). If the compiler lacks this support, attempts to
enable this feature are ignored.
- Switch to using GetLocalTime on Windows.
This code was part of a feature abandoned before retail. It cannot be
usefully used in campaigns. Remove it to reduce code size and simplify
later changes.
Commit f4b21088a0 ("Track vulcan ammo explicitly") fixed an original
retail bug that prevented the thief from stealing energy weapons,
because the thief could only steal weapons for which the player had ammo
and energy weapons never have ammo. This went unremarked for several
years, until a recent report of the new semantics as a game-breaking
regression because the thief is now "ridiculously potent".
Address this report, as well as an intermittently raised issue from
various users over time, by adding two new knobs to both the single
player "Gameplay" menu and the multiplayer setup screen: "Remove Thief
at level start" and "Prevent Thief Stealing Energy Weapons".
"Remove Thief" deletes the thief object during level load. It has no
impact on save games, and changing it after entering a level has no
effect on any thief already in the level.
"Prevent Thief Stealing" is checked at the moment of theft and, when
enabled, prevents stealing primary weapons other than Vulcan/Gauss.
This can be changed at will in single player and is immediately
effective. In multiplayer, this option can only be changed by the game
host in the pre-game setup.
For both knobs, there is one pair of checkboxes to control this as a
player preference, which applies in single player games. There is a
second pair of checkboxes in the multiplayer setup, which applies only
to multiplayer games. Therefore, in multiplayer, the host chooses thief
settings and all clients use the host's choice. The host may configure
the thief differently in multiplayer from how the host plays in single
player.
For users who wanted to remove the thief, no specific tally has been
kept for who requested it or when. Now that the code is being updated,
this is thrown in as an easy addition.

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.
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.
`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

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

All supported compilers have an acceptable <type_traits>. Commit
4cb3d46148 ("Move <type_traits> test to Cxx11RequiredFeature") made

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

Hat labels reserve an extra character for the arrow, which partially

x86_64-w64-mingw32-g++ -Wformat handling misparses the std::size_t

common/main/valptridx.tcc: In function 'void untyped_index_mismatch_exception::prepare_report(const char*, unsigned int, const void*, long int, const void*, const void*, char (&)[229], std::size_t)':
common/main/valptridx.tcc:36:182: error: format '%u' expects argument of type 'unsigned int', but argument 7 has type 'std::size_t {aka long long unsigned int}' [-Werror=format=]
This occurs even though the processed text uses %I64u (which is correct
for a `long long unsigned int`), not %u as shown in the error message.
static void prepare_report(const char *const filename, const unsigned lineno, const void *const array_base, const long supplied_index, const void *const expected_pointer, const void *const actual_pointer, char (&buf)[report_buffer_size], const std::size_t array_size)

}
In practice, all such sizes will fit in `unsigned int` because they are
the dimension of an array of large structures. Switch all platforms to
use `unsigned long`, which works everywhere and is at least as big as
`unsigned int`. Using `unsigned long` produces the same size as
`std::size_t` on all platforms other than Win64, where `unsigned long`
is only 32 bits due to the strange LLP64 model Microsoft picked.
Commit b32298df5a ("Rewrite powerup cap
code to centralize logic") centralized powerup cap code in the
powerup_cap_state class.
Commit 901a554e96 ("New powerup management
code: Addeed functions and packet type to ...") removed all use of
powerup_cap_state, but left the dead implementation present.
Commit 479f5ed584 ("Fix 'format specifies
type 'unsigned short' but the argument has type 'unsigned char''
warning") switched the already dead (but still compiled) code from %hu
to %hhu to fix a warning on OS X. Although the commit was written by
Chris, it was my suggestion to use %hhu. I neglected to test Windows
before suggesting it, so the change went in even though Windows does not
accept %hhu; this broke the Windows build. Fortunately, the code had
been dead for 11 months when the change was made, so the fix for Windows
is to remove the long dead code.
Descent 1 has no headlight powerup. Code to read headlights was
incorrectly added in 357e1b0144, but no code was added to write
headlights, so the Descent 1 lighting code checked for headlights that
never existed. Guard the headlight global variables and the associated
logic with if(D2).
Fixes: 357e1b0144 ("Made lighting code work with actual RGB values and added feature to let certain objects emit colored dynamic light as well as let mine flash red when control center destroyed (OpenGL-only at the moment)")
Expose sphere_intersects_wall and call it directly from
boss_fits_in_seg, so that boss_fits_in_seg does not need to modify the
position and segment of the boss during the test.
If boss has teleported before, even before a loaded state was saved, play the boss looping sound immediately when loading the saved game (if near the boss). Resolves issue #326.
When objp is nullptr, ai_door_is_openable assumes Buddy_objnum is a
valid object number, but this assumption is not guaranteed to be true.
When it is false, the game crashes. This crash can be triggered by a

Fix the crash by passing the robot of interest.

Macro LINE_SPACING previously used global grd_curcanv implicitly.
Change it to take a canvas argument. Change all callers to pass
grd_curcanv, so that usage is explicit.
As a macro, it always refers to the global grd_curcanv. This interferes
with converting canvas handling to be an argument. Expand GWIDTH so
that uses of grd_curcanv can be changed individually.
Movement handling has an ugly hack that tries to grab powerups near the
console player, but it reuses general collision handling and fails to
check whether the player is alive.
Add a liveness check. Place the check so that it happens once, before
the objects are scanned, rather than being needlessly repeated for every
object.
Refactor the collision code to let the movement hack skip the parts it
does not need.

Contains 2 calls - to obj_create and init_ai_object. For safety reasons and tidiness compared to using obj_create directly. The call to init_ai_object in recreate_thief was already redundant.
Use std::equal_range to find the upper and lower bounds in a single
binary search, rather than relying on a linear search to find the first
sought element.
In multi_do_frame(), replace call to window_close(Game_wind) with returning window_event_result::close whenever multi_quit_game is true. Only using this return value where multi_do_frame() is directly called by GameProcessFrame(). multi_quit_game will only be set back to 0 when a new multi game is started.
Closing a window within its handler is problematic - it can result in an unstable state.

Closing a window within its handler is problematic - it can result in an unstable state.
Valgrind warns when writing uninitialized data to a file. The Descent
savegame format requires writing certain fields that are no longer used.
Set those fields to 0 to prevent leaking stack data into the file.
init_player_stats_new_ship used select_primary_weapon and
select_secondary_weapon to assign the player's weapons. However, those
functions read the current weapon and jumped according to its value. A
new ship has no defined value for current weapons, so the jump triggered
an uninitialized value warning from Valgrind.
Add new functions set_primary_weapon, set_secondary_weapon that work
like the previous select_* functions, but always take the path used
for weapons not equal, without checking. This prevents the warnings
from Valgrind, as well as a theoretical risk of initializing the ship
improperly.
The declaration of valptridx_specialized_types needed to be found by
Argument Dependent Lookup, but this was inconvenient for some types.
Split the declaration of valptridx_specialized_types out from the
definition of valptridx global subtype.
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.
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.
When File->'Play in 320x200' is chosen, use StartNewGame(Current_level_num). For now use create_new_mission and Current_level_num = 1 every time. Also remove the now redundant hacks GM_EDITOR and editor_reset_stuff_on_level.
Move the main part of obj_link into obj_link_unchecked. Implement
obj_link as sanity check assertions followed by a call to
obj_link_unchecked. Remove caller-side writes that were present solely
to bypass the assertions, since the assertions can now be bypassed by
calling obj_link_unchecked directly.
The segiter code used objptridx because end is signalled by object_none,
and vobjptridx does not allow object_none. However, the compiler
produces better code if segment_object_range_t returns vobjptridx and
future cleanups are easier if iterating objects_in yields vobjptridx
objects. Add a special-case override of the normal checking rules, move
the required checks into segiter, and then let segiter break the rules
normally enforced by valptridx. Add a comment explaining that this
permits unsafe coding and should be done only with a clear understanding
of the responsibilities it brings.
One caller uses fuelcen_activate when segp->special != station_type.
Every other caller passes the type that was already on the segment.
Move the assignment into the one caller that needs it, then remove the
argument.
Make the listbox handlers and all sub-handlers (when_selected callbacks) return a window_event_result. Makes code more readable and removes one use of window_close, making it easier to inform event system if a window closes in future.
The only caller for get_multi_endlevel_poll1 was DoEndLevelScoreGlitz,
which only called it on an unreachable path. That path is now gone, so
remove get_multi_endlevel_poll1.

Callers are expected to filter out invalid numbers. Even if they do
not, the only use of the number is to match entries in Stuck_objects.
An invalid match could cause a call to vobjptr() with an invalid index,
but that would be diagnosed by the valptridx checking, so no invalid
memory access will occur.
