The update simply updates each nation's nat_money as it goes. Works.
Except it doesn't update when it runs on behalf of budget. But it
still checks nat_money to determine whether the nation is solvent.
These checks are all broken. Leads to massive mispredictions when
you'd go broke or solvent during a real update.
Track money unconditionally in nat_budget[].money. Delay update of
nat_money until prod_nat(). Replace separate money[] by new
nat_budget[].start_money. Closes bug#235.
Remaining difference between budget and update in the update test:
* #1: budget mispredicts plane #100 gets built (to be fixed)
* #2: budget shows ship, plane and land unit maintenance when broke,
but update damages them instead (correct)
* #2: sector -14,0 converts, quadrupling its taxes (correct)
* #4 & #5: bank with dust and bars taken over by che (correct)
* #4: plague deaths (correct)

Plane maintenance changes because pilot pay is now consistently
rounded down. Before it was rounded down for broke countries, else
up. The stock game's pilots earn a little less than $25, and solvent
countries save $1 per plane. The rounding doesn't make much sense

When we add up military payroll, we discard fractions. Payroll is
therefore lower than it should be, but I'm not fixing that now. The
number of military budget reports is actually computed from payroll,
and therefore also low.
The obvious way to fix that would be adding another out parameter to
tax() and upd_slmilcosts(). However, budget and the update track cost
and count of numerous things (sector products, unit maintenance and
building, ...), and it's time for a common way to do that.
Create struct budget_item for tracking cost and count, and struct
budget nat_budget[MAXNOC] for tracking a nation's budget. Track only
military for now; more to follow.
This fixes the military count. The cost of military remains low,
because we discard fractions exactly as before.

Traditionally, unused unused available work is discarded at the
update. Since commit d7a054c (v4.2.13), deities can configure (some)
unused work to "roll over", i.e. available work = some unused work +
this update's work.
Not discarding unused work reduces micromanagement incentives.
However, it also leads to unobvious behavior.
For instance, here's the obvious way to build a radar station: move in
enough people to make 200 work. Half of it is available for sector
building, and increases efficiency to 100%. Here's a not-so-obvious
way: move in enough people to make 134 work. 67 will be used to
increase efficiency to 67%. Now move your workers elsewhere. The
unused available work is enough to finish the job at the next update.
Similarly, neighbors could be surprised by sectors building bridges
despite having no visible workers.
Commit 7f4e59f (v4.2.15) let deities limit the amount rolled over:
unused work above rollover_avail_max is discarded. This became the
default with a value of 50 in commit 81a3e4c4, v4.3.31.
Limit it further so that "roll over" can increase the update's work by
no more than half, plus one. The extra point is there so that even a
tiny work force has a chance to eventually eke out the second point of
work needed to increase efficiency.

Rounding work down can lead to a bit of work micromanagement. For
instance, four military on a lonely island accomplish nothing in 60
ETU updates, but five will make one point of work per update. They
can build a 2% harbor in four updates, as long as rollover_avail_max
is at least 3. Six to eight will be no faster.
The people's work used to be rounded randomly until Empire 3's big
effort to make the update code work for budget switched to rounding it
down, perhaps accidentally.
Switch back to rounding randomly, so that players don't have to get it
exactly right. Four military now get to 2% in five updates on

The collection value of a sector is
sector value = sector type value * (sector efficiency + 100)
+ sum of item values
item value = item type value * amount
The sector and item type values are configurable.
The item type collect values aren't too far off the power values:
uid mnem pow val pow/val
0 "c" 50 1 50
1 "m" 100 0 inf
2 "s" 125 5 25
3 "g" 950 60 15.8

11 "h" 40 4 10
12 "u" 50 1 50
13 "r" 50 150 0.33
The power value is very roughly ten times the collect value, except
for civilians and uw it's 50, for rads its 0.33, and military are free
to collect. The latter two make no sense.
Replace the item type collect value by the power value / 50 for
people, and by the power value / 10 for everything else. This makes
collecting military, shells, guns and uw more expensive, and petrol,
bars, iron, oil and rads cheaper.
The sector type values are basically arbitrary. For instance, an iron
mine costs five times as much as a wilderness, but a third of an
uranium mine, regardless of actual resource contents.
Replace this by different arbitrary values:
sector value = (item value of materials necessary to build it
+ build cost) * efficiency / 100
+ sector type maximum population
+ sum of item values
Some sector types become cheaper, some more expensive.
Drop sect-chr and item selector value.

buildeff() rounds work and money up. Until recently, fractions could
only occur on tear-down, but with customized costs they can now also
occur on build-up.

shiprepair() limits the efficiency gain to how much the workers can
build, rounding randomly. It charges work, money and materials for
the efficiency actually gained, rounding work up, money down, and
materials randomly. Same for planerepair() and landrepair(). Has
always been that way.
If you get lucky with the random rounding, you may get a bit of extra
work done for free.
The budget command runs the update code, and can be off by one due to
different random rounding.
Sector production used to have the same issue, only more serious,
because a single unit of tech production matters much more for the
budget than a single point of unit efficiency gain. I fixed it in
commit 6f7c93c, v4.3.31.
Fix it for unit building the same way: limit efficiency gain to the
amount the workers can produce (no rounding). Work becomes a hard
limit, not subject to random fluctuations. Randomly round work and
money charged for actual gain, like we do for materials. On average,
this charges exactly the work and money that's used.
This lets budget predict how much gets built a bit more accurately.
It's still not exact, as the amount of work available for building
remains slightly random, and the build cost is randomly rounded.
The old rounding of work for ships carries the comment "I didn't use
roundavg here, because I want to penalize the player with a large
number of ships." Likewise for planes. Rounding work up rather than
randomly increases the work cost by 0.5 per ship, plane or land unit
on average. I could keep the penalty by adding 0.5 before random
rounding. Not worth it, since the effect is actually pretty trivial.
Let's examine a fairly extreme case: an airfield with 600 available
work repairing a huge number of lightly damaged planes, say f2 with
81% average efficiency. The old code lets the airfield repair roughly
600 / 6.5 = ~92 planes, the new code 600 / 6 = 100.

Replace the term
power value of materials and cost + 9
by
power value of materials and cost + maximum population / 1000 * 8 + 1
The value of ordinary sectors (maximum population 1000) doesn't
change. The stock game's mountains, plains and bridges are now worth
only 28% as much.
This concludes my tweaking of the power factor for now. I tested it
with data from a real game (Hvy Metal II). The effect is small: #5
overtakes #4, and the lead of #1 over #2 and #3 shrinks some. Closer
analysis finds the following reasons. The game had very expensive big
cities. Valuing them correctly gives countries with many cities a
noticeable boost. Planes are worth less than before, but the
difference is much larger for cheap planes. Big piles of construction
materials are worth much less, and shells, guns and bars are worth
more.

Building sectors can make you rate *lower* on the power chart, because
the power factor treats all sectors the same, regardless of build
materials and cost.
To avoid that, replace the term
efficiency / 10.0
by
(power value of materials + power value of cost + 9)
* efficiency/100.0
The value of ordinary sectors, which take no materials and cost $100,

to its materials and higher cost. The stock game's wilderness is
worth 10% less, because it costs nothing.

Update code shared with budget uses the bp map instead of the sector,
so that budget can track materials and work available in sectors for
ship, plane and land unit building without updating the sector file.
Unfortunately, the bp map can become stale during the update.
prepare_sects() doesn't update the bp map for sea sectors, unlike
budget's calc_all(). Instead, we rely on calloc()'s initialization.
Works, but is a bit unclean.
prepare_sects() updates the bp map after fallout, but neglects to
update it for any of the later sector updates (steps 1b to 1f in info
Update-sequence). Che can destroy materials and available work, and
the plague can kill military. The bp map stays out of date until
produce_sect() updates it again.
Since we deal with sector production and countries in increasing order
of country number, foreign ships, planes and land units owned by
countries with lesser numbers get built before their sector produces.
Building uses the stale bp map then, and can use materials and
available work destroyed by che or the plague. The update test
demonstrates the former case.
For stopped sectors or when the owner is broke, produce_sect() updates
only materials in the bp map, not available work. Nothing builds in a
stopped sector, but allies may build in your sectors even when you're
broke. They can use available work destroyed by che then.
Screwed up when Empire 3 made the update code work for budget.
Note that budget bypasses the flawed code: it prepares its bp map
itself instead of calling prepare_sects().
Rather than fixing prepare_sects(), use a null bp map for the update:
writes become no-ops, and reads read from the underlying sector. Not
only does this remove the possibility of the bp map going stale during
the update, it saves a bit of memory, too.
calloc()'s initialization is now dead. Switch to malloc().

We maintain a few sector invariants in sct_prewrite(). Since the

two should be consistent.
The update reverts deserted sectors to deity in three places:
do_plague(), populace() and produce_sect(). None of them is

populace() can revert unowned sectors to deity. This creates bogus
entries in the "lost" file. Harmless; messed up when the lost items
were added in 4.0.7. Visible in tests/smoke/final.xdump.
populace() fails to revert when there are only uw left. If PLAGUE is
enabled, do_plague() already reverted. Else, produce_sect() will.
This is the only case where they add value to populace(). Can be
traced back all the way to BSD Empire 1.1.
All three neglect to clear mobility. Harmless.
Fix populace()'s condition for reverting to deity, and make it clear
mobility. Drop the reverting from do_plague() and produce_sect().
populace() also resets state that applies to civilians when there are
none: work percentage, loyalty and old owner. However, it resets on
different conditions than sct_prewrite(). Messed up in Chainsaw;
before, populace() didn't reset at all.
For sectors without military, populace() fails to reset. This can
happen when the update wipes out civilians and military, say by plague
or fallout. The now bogus work percentage, loyalty and old owner
persist until sct_prewrite() runs on the next non-update sector
update. Except old owner is reset correctly by populace() when the
sector reverts to deity. It doesn't when the owner has a land unit
there.
Most of the time, this doesn't matter, as moving civilians into a
sector without civilians overwrites the sector's work percentage,
loyalty and old owner. However, airlifting and unloading civilians
fail when the old owner differs from the owner. Else they adopt the
sector's loyalty and work percentage (bug#49 and bug#255).
