The Windows exception handler probes the stack to determine how much can
be safely dumped, up to a fixed maximum number of bytes. A logic error
caused the probe function to start its stack probe lower than intended,
so the eventual dump code logs fewer pre-exception bytes than intended.
Fix that error so that the dump shows more pre-exception bytes.
Also, log the address of the ud2 instruction, so that the effective load
address of the module can be determined. Without this, ASLR makes
reading the dumps needlessly difficult.
Rather than use an inline wrapper and rely on the compiler optimizer to
redirect gr_set_current_canvas(nullptr) to gr_set_default_canvas,
rewrite all relevant calls directly in the source.
git grep -l 'gr_set_current_canvas' | xargs sed -i -e 's:gr_set_current_canvas(\s*NULL\|nullptr\s*);:gr_set_default_canvas();:'
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.
Both the `if` and `else` paths had the same loop and post-loop
processing. The `if` path was a strict subset of the `else` path. The
`else` path had one setup statement, and was otherwise equal to the `if`
path. Move the shared statements outside the guarded path.
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.

Some Linux libraries print their own messages to stdout/stderr,
particularly in case of severe errors. Decorate messages generated by
Rebirth to distinguish them from library generated messages.
For specific blacklisted renderers, add a message informing the user
that the blacklist matched and changed settings.
Only one caller exists, and that caller alway passes a non-nullptr
value. Switch to a reference and remove the unused special case to
handle a nullptr input.
Most uses pass an orientation matrix. All sites are deterministic about
whether a matrix is passed. Make the matrix mandatory for sites that
passed it, and split out a separate version of g3_start_instance_matrix
for the 2 sites which do not provide orientation.
