Creating a new disk is the major latency cost of creating a
new instance. If we reuse a previous disk image, the VM and
CoreOS boot much quicker and start building again.
So add a mode where we don't mark the disk as delete-on-death
when we create it, and we search for a suitably-named existing
one on creation and try to reuse it.
It's a cache, essentially. It's still stateless.

Then make the coordinator and linux environment Makefiles have
an upload target. Amusingly, this actually worked: the Docker
images now tar + compress + upload over HTTP all in a stream,
without even knowing how large the resulting tar.gz will be until
it's done uploading.

This tool creates String methods from constant definitions.
It's a time-saver designed to be used from go generate.
The methods generated are efficient, more so than one
is likely to create by hand.
Given
package date
type Day int
const (
Monday Day = iota
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
)
the command
stringer -type Day
will create the file day_string.go containing
package date
import "fmt"
var (
_Day_indexes = []uint8{6, 13, 22, 30, 36, 44, 50}
_Day_names = "MondayTuesdayWednesdayThursdayFridaySaturdaySunday"
)
func (i Day) String() string {
if i < 0 || i >= Day(len(_Day_indexes)) {
return fmt.Sprintf("Day(%d)", i)
}
hi := _Day_indexes[i]
lo := uint8(0)
if i > 0 {
lo = _Day_indexes[i-1]
}
return _Day_names[lo:hi]
}
There are several strategies for the created method chosen according to
the structure of the sequence of constants.
Handles integer types only, both signed and unsigned. That's probably
all that is needed.
Tests to follow, but the test structure will be large so sending this out
separately. The code has been heavily hand-tested but there are
some bugs. Don't depend on this until the tests are installed.

Recent changes in the runtime caused the interpreter to call 'getg',
and it should never have gotten that far.
Also, delete bodies of "runtime" functions, since they're too magical.
This makes missing intrinsics cause very obvious failures.

It returns the value formerly returned by Pkg(), i.e. the imported package.
Pkg() now returns the package enclosing the import statement,
which is consistent with all other Objects.

They were from a time before we had the os/exec package, if
memory serves.
Also, make verbose also mean that the main build's stdout
and stderr go to the real stdout and stderr as well.
I'll want that for the Docker-based builder.

LookupFieldOrMethod now also decides whether a found
method is actually in the method set. Simplifies call
sites. Added corresponding API tests.
TODO (separate CL): Decide what the correct value for
the indirect result should be (as required for code
generation). For now, the result value for indirect
is unchanged from before if a field/method is found.

Good checkpoint. Can now do builds by hand.
Next step is coordinator server in front of this, and things
to fire up beefy GCE instances running CoreOS and each build
in its own Docker container. See README for how to do a single

Be careful not to complain about math.Log and cmplx.Log.
Seems worthwhile since t.Log and t.Logf are often written but

This makes it easier to parse via external tools such as editors. Editors can
show each function in a list and jump directly to each function with this
additional information. This pattern can be seen in other Go tools such as "go
test" in the form of:

We want to make an if look like two blocks and have the coverage
report for the else block decorate the "else" keyword with the right
color. To do this, we adjust the apparent starting point of the else
block to include the "else".
The previous code assumed the way to do this was to move the
width of "else " backwards from the else block's opening brace, but
that assumes there is a space there. Instead, we now just start the
else block exactly at the end of the if block. Simpler, cleaner, and
fixes a bug.

Currently for every benchmark/metric we show all changes for all builders x procs.
With 4 builders and 5 procs, that's 20 changes (20 red/green boxes in a single cell).
Instead show only maximum change for every benchmark/metric.
This significantly reduces clutter in UI.
When you click on the red/green box, you can see the rest of the changes.

Currently we still see some flakes on perf dashboard (e.g. sys-stack is quite frequent).
I am planning to run real perf builder with 5 different values of GOMAXPROCS,
so we can require 3 builders to agree on a change instead of 2.
This will provide 20x improvement in flake detection.
At the same time lower noise bar from 1.2 to 1.1, as I see some real perf changes gets ignored as noise.
All these magic numbers affect only representation of data, but not the data stored in DB.
So we can continue freely tuning them later. There are no significant risks here.
