In reviewing CL 466875, I noticed that the implementation of
splitPkgConfigOutput from CL 86541 referred to another specific
implementation, and that implementation has had recent changes to fix
deviations from the POSIX specification for shell argument parsing.
Curious about those changes, I decided to fuzz the function to check
whether it agreed in practice with the way a real shell parses
arguments in POSIX mode. It turned out to deviate in several edge
cases, such as backslash-escapes within single quotes, quoted empty
strings, and carriage returns. (We do not expect to see carriage
returns in pkg-config output anyway, but the quote handling might
matter.)
This change updates the implementation to refer to the POSIX
documentation instead of another implementation, and confirms the
behavior with a fuzz test. It may introduce minor deviations from the
pkgconf implementation that was previously used as a reference, but if
so it is plausible that those could be fixed upstream in pkgconf
(like the other recent changes there).
For #35262.

The sweep assist computation is intentionally racy for performance,
since the specifics of sweep assist aren't super sensitive to error.
However, if overflow occurs when computing the live heap delta, we can
end up with a massive sweep target that causes the sweep assist to sweep
until sweep termination, causing severe latency issues. In fact, because
heapLive doesn't always increase monotonically then anything that
flushes mcaches will cause _all_ allocating goroutines to inevitably get
stuck in sweeping.
Consider the following scenario:
1. SetGCPercent is called, updating sweepHeapLiveBasis to heapLive.
2. Very shortly after, ReadMemStats is called, flushing mcaches and
decreasing heapLive below the value sweepHeapLiveBasis was set to.
3. Every allocating goroutine goes to refill its mcache, calls into
deductSweepCredit for sweep assist, and gets stuck sweeping until
the sweep phase ends.
Fix this by just checking for overflow in the delta live heap calculation
and if it would overflow, pick a small delta live heap. This probably
means that no sweeping will happen at all, but that's OK. This is a
transient state and the runtime will recover as soon as heapLive
increases again.
Note that deductSweepCredit doesn't check overflow on other operations
but that's OK: those operations are signed and extremely unlikely to
overflow. The subtraction targeted by this CL is only a problem because
it's unsigned. An alternative fix would be to make the operation signed,
but being explicit about the overflow situation seems worthwhile.
Fixes#57523.

Message marshalling makes use of BytesOrPanic a lot, under the
assumption that it will never panic. This assumption was incorrect, and
specifically crafted handshakes could trigger panics. Rather than just
surgically replacing the usages of BytesOrPanic in paths that could
panic, replace all usages of it with proper error returns in case there
are other ways of triggering panics which we didn't find.
In one specific case, the tree routed by expandLabel, we replace the
usage of BytesOrPanic, but retain a panic. This function already
explicitly panicked elsewhere, and returning an error from it becomes
rather painful because it requires changing a large number of APIs.
The marshalling is unlikely to ever panic, as the inputs are all either
fixed length, or already limited to the sizes required. If it were to
panic, it'd likely only be during development. A close inspection shows
no paths for a user to cause a panic currently.
This patches ends up being rather large, since it requires routing
errors back through functions which previously had no error returns.
Where possible I've tried to use helpers that reduce the verbosity
of frequently repeated stanzas, and to make the diffs as minimal as
possible.

Reader.ReadForm is documented as storing "up to maxMemory bytes + 10MB"
in memory. Parsed forms can consume substantially more memory than
this limit, since ReadForm does not account for map entry overhead
and MIME headers.
In addition, while the amount of disk memory consumed by ReadForm can
be constrained by limiting the size of the parsed input, ReadForm will
create one temporary file per form part stored on disk, potentially
consuming a large number of inodes.
Update ReadForm's memory accounting to include part names,
MIME headers, and map entry overhead.
Update ReadForm to store all on-disk file parts in a single
temporary file.
Files returned by FileHeader.Open are documented as having a concrete
type of *os.File when a file is stored on disk. The change to use a
single temporary file for all parts means that this is no longer the
case when a form contains more than a single file part stored on disk.
The previous behavior of storing each file part in a separate disk
file may be reenabled with GODEBUG=multipartfiles=distinct.

With these changes, it should behave identically to how the indexed

from the drive the memory mapped file is on being ejected) cause
a runtime fault that can not be caught by debug.SetPanicOnFault.
On Unix systems, on the other hand, this causes a SIGBUS signal,
which can be caught by debug.SetPanicOnFault. Given that the
documentation of debug.SetPanicOnFault mentions handling memory
mapped files, this is arguably the correct behaviour.
Add handling, analogous to SIGBUS, to EXCEPTION_IN_PAGE_ERROR

Darwin needs the osinit_hack call to fix some bugs in the Apple libc
that surface when Go programs call exec. On iOS, the functions that
osinit_hack uses are not available, so signing fails. But on iOS exec
is also unavailable, so the hack is not needed. Disable it there,
which makes signing work again.
Fixes#58323.

For unification we only need the handles map.
The type parameter list was stored for reproducible printing only,
but we can achieve the same effect with sorting.
This opens the door to adding type parameters from different
types/functions that we may want to infer together. They may
be added through separate "addTypeParams" calls in the future.
Printing (which is used for debugging only) will remain reproducible.

Rather than referring back to the type parameter list stored with
the unifier, return inferred types for a given list of type parameters.
This decouples the unifier more and opens the door for inference to
consider type parameters from multiple types for inference.
While at it, introduce an internal flag to control whether
inference results of the two inference implementations should
be compared or not.
