runtime: improve error messages after allocating a stack that is too big

2020-09-20T09:54:44+00:00

In the current implementation, we can observe crashes after calling
debug.SetMaxStack and allocating a stack larger than 4GB since
stackalloc works with 32-bit sizes. To avoid this, we define an upper
limit as the largest feasible point we can grow a stack to and provide a
better error message when we get a stack overflow.

Fixes #41228

runtime/debug: provide Addr method for errors from SetPanicOnFault

2020-09-18T17:21:06+00:00

When we're building a panic that's triggered by a memory fault when
SetPanicOnFault has been called, include an Addr method. This
method reports the address at which the fault occurred.

runtime/debug: don't trigger a GC on SetGCPercent

2017-04-21T17:42:02+00:00

Currently SetGCPercent forces a GC in order to recompute GC pacing.
Since we can now recompute pacing on the fly using gcSetTriggerRatio,
change SetGCPercent (really runtime.setGCPercent) to go through
gcSetTriggerRatio and not trigger a GC.

Fixes #19076.

runtime/debug: don't run a GC when setting SetGCPercent negative

2017-02-10T18:28:37+00:00

If the user is calling SetGCPercent(-1), they intend to disable GC.
They probably don't intend to run one. If they do, they can call
runtime.GC themselves.

all: use sort.Slice where applicable

2016-10-04T05:10:56+00:00

I avoided anywhere in the compiler or things which might be used by
the compiler in the future, since they need to build with Go 1.4.

I also avoided anywhere where there was no benefit to changing it.

I probably missed some.

all: make copyright headers consistent with one space after period

2016-03-01T23:34:33+00:00

This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.

Go policy has been single space after periods in comments for some time.

The copyright header template at:

    https://golang.org/doc/contribute.html#copyright

also uses a single space.

Make them all consistent.

2015-07-11T14:36:33+00:00

The one in misc/makerelease/makerelease.go is particularly bad and
probably warrants rotating our keys.

I didn't update old weekly notes, and reverted some changes involving
test code for now, since we're late in the Go 1.5 freeze. Otherwise,
the rest are all auto-generated changes, and all manually reviewed.
