I originally thought that there was no harm in reading or skipping
zero lines after we have already reached the end of the image.
However, once we reach the end of the image, onFinish() is
automatically called. Performing a read or a skip after
the call to onFinish() is invalid and will cause onFinish()
to be called a second time (which is also invalid).
Seems like the code requires good behavior and the test is
wrong.

This experiment replaces the label used in the aaxfermodes gm with
aliased text generated from paths common to all platforms.
Since there is no way today to generate all dm output from trybots,
this will be checked in to confirm that this strategy provides simpler
output across devices.
This does not introduce a new public interface; instead, dm uses
a extern backdoor to install the SkTypeface::CreateFromName
handler.

We may want to enable swizzles to 565
for images that are encoded in a format
similar to 565, however, we do not want
to take images that decode naturally to
kN32 and then convert them to 565.
***Enable swizzles to kIndex_8. For images
encoded in a color table format, we suggest
that they be decoded to kIndex_8. When we
decode, we only allow conversion to kIndex_8
if it matches the suggested color type (except
wbmp which seems good as is).

Tasks that produce a non-fatal error will bail out before writing their output to
disk and hash to dm.json, but not count as failures.
This also makes true failures bail out before writing their results. If the DM
program failed, we probably don't want to triage that image result.
We use this new feature first to skip image subset decoding when we detect it's
not supported. Here's a snippet of an example run, where in this case only
.webp are subset decodable:
...
( 15MB 12) 172µs 8888 subset color_wheel.jpg (skipped: Subset decoding not supported.)
( 15MB 11) 9.05ms 8888 subset randPixels.webp
( 16MB 10) 863µs 8888 subset baby_tux.png (skipped: Subset decoding not supported.)
...
Only outputs corresponding to the .webp show up, both on disk and in the .json.

SkStream is a stateful object, so it does not make sense for it to have
multiple owners. Make SkStream inherit directly from SkNoncopyable.
Update methods which previously called SkStream::ref() (e.g.
SkImageDecoder::buildTileIndex() and SkFrontBufferedStream::Create(),
which required the existing owners to call SkStream::unref()) to take
ownership of their SkStream parameters and delete when done (including
on failure).
Switch all SkAutoTUnref<SkStream>s to SkAutoTDelete<SkStream>s. In some
cases this means heap allocating streams that were previously stack
allocated.
Respect ownership rules of SkTypeface::CreateFromStream() and
SkImageDecoder::buildTileIndex().
Update the comments for exceptional methods which do not affect the
ownership of their SkStream parameters (e.g.
SkPicture::CreateFromStream() and SkTypeface::Deserialize()) to be
explicit about ownership.
Remove test_stream_life, which tested that buildTileIndex() behaved
correctly when SkStream was a ref counted object. The test does not
make sense now that it is not.
In SkPDFStream, remove the SkMemoryStream member. Instead of using it,
create a new SkMemoryStream to pass to fDataStream (which is now an
SkAutoTDelete).
Make other pdf rasterizers behave like SkPDFDocumentToBitmap.
SkPDFDocumentToBitmap delete the SkStream, so do the same in the
following pdf rasterizers:
SkPopplerRasterizePDF
SkNativeRasterizePDF
SkNoRasterizePDF

counted objects.

Since we just 'define' them, but not attribute anything to them, like
'1' for example, cpp expands it to nothing and that breaks the "#if"
clauses.
To fix that, uses "#if defined(...)" which will correctly check if your
macro name was defined or not.

Underscore is used as a field separator sometimes when parsing the task
name into a list of config, mode, etc. (This itself is dumb and TODO(mtklein): fix.)
Underscores in the field names will really mess that up, both in directories generated
from human-mode -w, and in the .json file.

This lets us distinguish the original ("direct") runs from their replay modes.
There was a bit of a bug in here now fixed: we used the first entry in
fSuffixes as the config. Actually, the last entry in suffixes is the
config. This is moot when there's only one suffix (direct drawing), but
for mode drawing we were recording the mode as config! Now it's correct.
Here's some example output where I rigged a bunch of modes to fail:

I have checked that no two premultiplied colors map to the same unpremultiplied
color (math nerds: unpremultiplication is injective), so a change in
premultiplied SkBitmap will always imply a change in the encoded

DM's striking off into its own JSON world. This gets strawman implementations
in place for writing and reading a JSON file mapping test name to hashes.
For what it's worth, I basically want to change _all_ these pieces,
- MD5 is slow and we can replace it with something faster,
- JSON schema needs room to grow more data,
- it'd be nice to hash once instead of twice when reading and writing,
- this code wants lots of refactoring,

SkTaskGroup is like SkThreadPool except the threads stay in
one global pool. Each SkTaskGroup itself is tiny (4 bytes)
and its wait() method applies only to tasks add()ed to that
instance, not the whole thread pool.
This means we don't need to bring up new thread pools when
tests themselves want to use multithreading (e.g. pathops,
quilt). We just create a new SkTaskGroup and wait for that
to complete. This should be more efficient, and allow us
to expand where we use threads to really latency sensitive
places. E.g. we can probably now use these in nanobench
for CPU .skp rendering.
Now that all threads are sharing the same pool, I think we
can remove most of the custom mechanism pathops tests use
to control threading. They'll just ride on the global pool
with all other tests now.
This (temporarily?) removes the GPU multithreading feature
from DM, which we don't use.
On my desktop, DM runs a little faster (57s -> 55s) in
Debug, and a lot faster in Release (36s -> 24s). The bots
show speedups of similar proportions, cutting more than a

For now this only creates a degenerate bounding box hierarchy where all ops

Not quite sure why QuadTree and TileGrid aren't drawing right---haven't even

Allow GM results to be compared across machines and platforms by
standardizing the fonts used by all tests.
This adds runtime flags to DM to use either the system font context (the
default), the fonts in the resources directory ( --resourceFonts ) or a set
of canonical paths generated from the fonts ( --portableFonts ).
This CL should leave the current DM results unchanged by default.
If the portable font data or resource font is missing when DM is run, it
falls back to using the system font context.
The create_test_font tool generates the paths and metrics read by DM
with the --portableFonts flag set, and generates the font substitution
tables read by DM with the --resourceFonts flag set.
If DM is run in SkDebug mode with the --reportUsedChars flag set, it
generates the corresponding data compiled into the create_test_font tool.
All GM tests set their typeface information by calling either
sk_tool_utils::set_portable_typeface or
sk_tool_utils::portable_typeface .
(The former takes the paint, the latter returns a SkTypeface.) These calls
can be removed in the future when the Font Manager can be superceded.

Share command flags between dm and unit tests.
Also, allow dm's core to be included by itself and iOSShell.
Command line flags that are the same (or nearly the same) in DM
and in skia_tests have been moved to common_flags. Authors,
please check to see that the shared common flag is correct for
the tool.
For iOS, the 'tool_main' entry point has a wrapper to allow multiple
tools to be statically linked in the iOSShell.
Since SkCommandLineFlags::Parse can only be called once, these calls
are disabled in the IOS build.
Since the iOS app directory is dynamically assigned a name, use '@' to
select it. (This is the same convention chosen by the Mobile Harness
iOS file system utilities.)
Move the heart of dm.gyp into dm.gypi so that it can be included by
itself and iOSShell.gyp.

Replay isn't that helpful of a test any more now that we have the more
stringent Quilt tests. Quilt was missing bounding box hierarchies, though,
while Replay was sort of testing RTree (pointlessly, as it was drawing without
any clip). Now Quilt does everything, testing RTree, QuadTree, and TileGrid.
Quilt mode now falls back to drawing all at once (i.e. Replay) for GMs that
don't tile perfectly. Still a TODO to make this check more flexible than exact
pixel matches.
Two GMs fail when using a BBH:
- imageresizetiled
- resizeimagefilter
We think we're not adjusting the bounds of save layers by their paint.
This is probably a bug, but one to be fixed separately from adding new tests.

Now that we're drawing tiles threaded like implside painting, remove the checks
that those lock counts are balanced. They're just not right for anyone anymore.
SkBitmaps themselves are not threadsafe (even const ones), so shallow copy them
on playback of an SkRecord. (The underlying SkPixelRefs are threadsafe.)
Simplify quilt drawing by using SkBitmap::extractSubset. No need for locking.
Bump up to 256x256 tiles. 16x16 tiles just murders performance (way too much
contention). This has the nice side effect of letting us enable a bunch more
GMs for quilt mode; they drew wrong with small tiles but exactly right with large.

I'm soon going to have SkRecorder start calling getTotalMatrix(), which
would be broken in write-only mode. That change is big and nebulous,
but it's clear kWriteOnly needs to go, so we might as well kill it now.
My notes in bench_playback about kWriteOnly mode being important were
probably overly cautious. I now think this is a fair enough comparison
even re-recording into a read-write canvas.

Like yesterday's change to run CPU-parent child tasks serially in thread, this
reduces peak memory usage by improving the temporaly locality of the bitmaps we
create.
E.g. Let's say we start with tasks A B C and D
Queue: [ A B C D ]
Running A creates A' and A", which depend on a bitmap created by A.
Queue: [ B C D A' A" * ]
That bitmap now needs sit around in RAM while B C and D run pointlessly and can
only be destroyed at *. If instead we do this and push dependent child tasks
to the front of the queue, the queue and bitmap lifetime looks like this:
Queue: [ A' A" * B C D ]
This is much, much worse in practice because the queue is often several thousand
tasks long. 100s of megs of bitmaps can pile up for 10s of seconds pointlessly.
To make this work we add addNext() to SkThreadPool and its cousin DMTaskRunner.
I also took the opportunity to swap head and tail in the threadpool
implementation so it matches the comments and intuition better: we always pop
the head, add() puts it at the tail, addNext() at the head.

These tasks tend to do similar things with similar sized bitmaps, so running
them serially means we tend to hold 2x bitmaps at a time (golden and
comparison) instead of (1+k)x bitmaps (golden and k concurrent comparisons).
We still migrate GPU task's children over to the main CPU thread pool,
because they'll run faster there and free up capacity on the GPU thread.

to set this flag (and thus instantiate an SkPicture-derived

DM will now read and write a custom image format, which begins first with a
normal PNG, but also includes the bitmap's raw pixels. Most tools (file
browser, Preview, Chrome, Skia image decoder) will read the file as PNG. DM
skips the encoded PNG and reads the raw pixels instead.
This scheme allows perfect pixel comparisons that never go through PM -> UPM or
UPM -> PM conversions, as long as you compare on a machine with the same native
pixel format as the machine which generated the images. Since we've only ever
used this to do same-machine comparisons, that's more than good enough for now.
We could convert as needed to a standardized PM pixel format if we find we want
these files to be portable.
DM -w output now does increase to ~1.3G. If that turns out to be annoyingly
big, I'm sure I can come up with a simple pixelwise RLE instead of writing
uncompressed pixels.

The main meat of things is in SkThreadPool. We can now give SkThreadPool a
type for each thread to create and destroy on its local stack. It's TLS
without going through SkTLS.
I've split the DM tasks into CpuTasks that run on threads with no TLS, and
GpuTasks that run on threads with a thread local GrContextFactory.
The old CpuTask and GpuTask have been renamed to CpuGMTask and GpuGMTask.
Upshot: default run of out/Debug/dm goes from ~45 seconds to ~20 seconds.

We've already decoded the PNGs themselves into unpremultiplied bitmaps with native byte order. SkColor is just not the right choice unless you get lucky.
dm -w /tmp/dm && dm -r /tmp/dm still works on Linux, and it's much closer to working on Mac:

PNGs store unpremultiplied colors, so we have to convert back and forth with
SkBitmap. This is lossy. GM solves this problem by stripping the alpha
channel before writing the PNG.
This flips it around, converting the GM's output to unpremultiplied as needed. This way each pixel goes from premul to unpremul once, never back.
Tested:
out/Release/dm -w /tmp/w --config 565 8888 gpu
out/Release/dm -r /tmp/w --config 565 8888 gpu

DM writes out its images in a hierarchy that's a little different than GM,
so this can't read GM's output. But it can read its own, written with -w.
Example usage:
$ out/Release/dm -w /tmp/baseline
$ out/Release/dm -r /tmp/baseline -w /tmp/new
(and optionally)
$ mkdir /tmp/diff; out/Release/skdiff /tmp/baseline /tmp/new /tmp/diff
GM's IndividualImageExpectationsSource and Expectations are a little too eager
about decoding and hashing the expected images, so I took the opportunity to
add DM::Expectations that mostly replaces skiagm::ExpectationsSource and
skiagm::Expectations in DM. It mainly exists to move the image decoding and
comparison off the main thread, which would otherwise be a major speed
bottleneck.
I tried to use skiagm code where possible. One notable place where I differed
is in this new feature. When -r is a directory of images, DM does no hashing.
It considerably faster to read the expected file into an SkBitmap and do a
byte-for-byte comparison than to hash the two bitmaps and check those.
The example usage above isn't quite working 100% yet. Expectations on some GMs
fail, even with no binary change. I haven't pinned down whether this is due to
- a bug in DM
- flaky GMs
- unthreadsafe GMs
- flaky image decoding
- unthreadsafe image decoding
- something else
but I intend to. Leon, Derek and I have suspected PNG decoding isn't
threadsafe, but are as yet unable to prove it.
I also seem to be able to cause malloc to fail on my laptop if I run too many
configs at once, though I never seem to be using more than ~1G of RAM. Will
track that down too.

This is sort of the near-minimal proof-of-concept skeleton.
- It can run existing GMs.
- It supports most configs (just not PDF).
- --replay is the only "fancy" feature it currently supports
Hopefully you will be disturbed by its speed.
