Code dealing with money mixes int and long pretty haphazardly.
Harmless, because practical amounts of money fit into int on any
machine capable of running the server. Clean up anyway.
meltitems() computes #items * etus per update * fallout in type long.
Theoretical maximum is ITEM_MAX * etus * FALLOUT_MAX = 99980001 *
etus. Can overflow 32 bits for etus > 21. Has been broken since the
introduction of fallout in KSU.
Compute the product in double instead.
Why upgrade? I'm not a lawyer, but here's my take on the differences
to version 2:
* Software patents: better protection against abuse of patents to
prevent users from exercising the rights under the GPL. I doubt
we'll get hit with a patent suit, but it's a good move just on
general principles.
* License compatibility: compatible with more free licenses, i.e. can
"steal" more free software for use in Empire. I don't expect to steal
much, but it's nice to have the option.
* Definition of "source code": modernization of some details for today's
networked world, to make it easier to distribute the software. Not
really relevant to us now, as we normally distribute full source code.
* Tivoization: this is about putting GPL-licensed software in hardware,
then make the hardware refuse to run modified software. "Neat" trick
to effectively deny its users their rights under the GPL. Abuse was
"pioneered" by TiVo (popular digital video recorders). GPLv3 forbids
it. Unlikely to become a problem for us.
* Internationalization: more careful wording, to harden the license
outside the US. The lawyers tell us it better be done that way.
* License violations: friendlier way to deal with license violations.
This has come out of past experience enforcing the GPL.
* Additional permissions: Probably not relevant to us.

Replace the fixed $1 per ETU maintenance for capital/city sectors that
are at least 60% efficient by a configurable maintenance cost, payable
regardless of efficiency. The only change in the default
configuration is that inefficient capitals now pay maintenance.
Charging sector maintenance regardless of efficiency is consistent
with unit maintenance.
New struct dchrstr member d_maint and sector-chr selector maint. Make
show_sect_build() show it. Change produce_sect() to record
maintenance in new slot p_sect[SCT_MAINT] instead of abusing
p_sect[SCT_CAPIT]. Replace the "Capital maintenance" line in budget
by "Sector maintenance".
Food supply during update adds complexity to the update. How much
good it does to players is highly doubtful; certainly nobody can rely
on it. It isn't covered by the starvation command. Starving ships or
land units can steal enough food from their sector to make it starve,
too. Finally, the supply code is notoriously hard to use correctly.
We don't know of issues with the update's use, but we haven't
convinced ourselves that there aren't any either.
negative. Some places considered $0 as bankrupt, some didn't. Fix
the ones that did:
(repo_list): report command misreported countries with $0 as broke.
(init_nats): If you had $0, logging out and back in bankrupted you.
(produce_sect, upd_ship): Failed to build sectors and produce stuff
for countries with $0.
This is more robust than using bp_put_item() for those elements of
vec[] that the call may change. The old code missed some changes:
upd_buildeff() changing population when tearing down a big city,
enlist(), and produce(). The first two should have been harmless, the
last one made budget mispredict repairs when required materials were
produced in the same update.
type. Make it abstract because that's possible. Change data layout
so that the slots belonging to a sector are together in memory, it's
nicer to the cache.
(bp): The new type. Users changed.
(get_wp): Update accordingly.
(alloc_bp): New.
(update_main, calc_all): Use it. Before, calc_all() allocated 1/7
more than necessary.
so that stopped sectors don't repair units. The update sequence
masked this bug until its change in src/lib/update/main.c rev. 1.25,
but use of budget priorities (gone since rev. 1.24) could unmask it.
other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
(P_LCM, P_HCM, P_TLEV, P_RLEV, P_ELEV, P_HLEV, P_URAN): Use -1 instead
of 0 for `no product', shift down product indexes and update
product.config and sector.config accordingly.
(budg, prod, show_sect_capab, produce, produce_sect): Adapt test for
no product.
(ef_elt_byname): Remove the hack to hide pchr[0].
(prod_eff): Oops on no product.
regardless of the option, but forced to sct_effic when disabled. This
screws up sct_defense when you disable DEFENSE_INFRA. Implement it
more like FALLOUT: use sct_defense if enabled, else sct_effic. The
change should be invisible except in xdump, which shows the real
sct_defense. Closes#804641.
(SCT_DEFENSE): New.
(dump, sinfra, sector_strength): Use it.
(eff_bomb, build_bridge, build_tower, new, buildeff, sect_damage)
(put_combat, checksect, produce_sect): Don't force sct_defense to
sct_effic when DEFENSE_INFRA is disabled.
