runtime/pprof/internal/profile: move internal/pprof/profile here

2017-02-24T20:45:21+00:00

Nothing needs internal/pprof anymore except the runtime/pprof tests.
Move the package here to prevent new dependencies.

runtime/pprof: merge internal/protopprof into pprof package

2017-02-10T13:09:19+00:00

These are very tightly coupled, and internal/protopprof is small.
There's no point to having a separate package.

runtime/pprof/internal/protopprof: fix test on s390x

2016-11-22T20:57:16+00:00

Applies the fix from CL 32920 to the new test TestSampledHeapAllocProfile
introduced in CL 33422. The test should be skipped rather than fail if
there is only one executable region of memory.

Updates #17852.

runtime/pprof: generate heap profiles in compressed proto format

2016-11-22T15:54:58+00:00

When debug is 0, emit the compressed proto format.
The debug>0 format stays the same.

runtime/pprof/internal: delete package gzip0

2016-11-11T16:58:05+00:00

rsc's change golang.org/cl/32455 added a mechanism
that allows pprof to depend on gzip without introducing
an import cycle. This obsoletes the need for the gzip0
package, which was created solely to remove the need
for that dependency.

runtime/pprof: output CPU profiles in pprof protobuf format

2016-11-10T21:07:48+00:00

This change buffers the entire profile and converts in one shot
in the profile writer, and could use more memory than necessary
to output protocol buffer formatted profiles. It should be
possible to convert each chunk in a stream (maybe maintaining
some minimal state to output in the end) which could save on
memory usage.

Fixes #16093

runtime/pprof/internal/protopprof: skip TestTranslateCPUProfileWithSamples if < 2 mappings

2016-11-09T18:22:00+00:00

A Go binary may only have 1 executable memory region if it has been
linked using internal linking. This change means that the test will
be skipped if this is the case, rather than fail.

Fixes #17852.

runtime/pprof/internal: add package protopprof

2016-11-08T19:39:16+00:00

This change adds code, originally written by Russ Cox 
and open-sourced by Google, that converts from the "legacy"
binary pprof profile format to a struct representation of the
new protocol buffer pprof profile format.

This code reads the entire binary format for conversion to the
protobuf format. In a future change, we will update the code
to incrementally read and convert segments of the binary format,
so that the entire profile does not need to be stored in memory.

This change also contains contributions by Daria Kolistratova
 from the rolled-back change
golang.org/cl/30556 adapting the code to be used by the package
runtime/pprof.

This code also appeared in the change golang.org/cl/32257, which was based
on Daria Kolistratova's change, but was also rolled back.
