Stream `.rrd` files #2412

jprochazk · 2023-06-13T15:17:38Z

What

Instead of waiting for the .rrd file to finish downloading, stream_rrd_from_http now uses ehttp::streaming and parses messages as data is streamed in.

As part of this change, compression now uses the LZ4 block format instead of the LZ4 frame format. This is a breaking change to the RRD format.

That nyud change looks very suspicious - this branch hasn't merged in main with the new jpeg_quality flag that has been added to nyud and colmap.

I think its time to add a docstring to re_log_encoding/src/lib.rs explaining how messages are encoded on the wire

emilk

I've done a partial review, and it looks really good so far!

But I think ChunkBuffer has some nasty bugs in it, and I suspect it can be simplified quite a bit.

+        let mut decoder = StreamDecoder::new();
+        for chunk in data.chunks(1) {
+            decoder.push_chunk(chunk.to_vec());

+        for _ in 0..16 {
+            assert_message_ok!(decoder.try_read());
+        }
+    }


you should also test that you can:

call decoder.try_read() without first pushing any chunks (and get None)

push a few chunks, get a few things out of decoder.try_read(), then None, and then push the rest of the chunks and read the rest of the messages (i.e. actually stream!)

push chunks of various sizes (not just the edge-case of size 1, which never tests the Cursor part of Chunk

call decoder.try_read() without first pushing any chunks (and get None)

This was added to the stream_something_chunks_{compressed,uncompressed} tests

push a few chunks, get a few things out of decoder.try_read(), then None, and then push the rest of the chunks and read the rest of the messages (i.e. actually stream!)

push chunks of various sizes (not just the edge-case of size 1, which never tests the Cursor part of Chunk

I added the following tests for this:

stream_3x16_chunks, which pushes 3 chunks of 16 bytes, then tries to read a message. It continues to do this until it reads all the messages, which are then compared against the input.

stream_irregular_chunks, which does the same thing, but pushes 2 chunks of N bytes at a time, where N comes from a repeating pattern.

It would be nice with a debug-level log when we reach the end of the HTTP stream. It will make testing the streaming behavior easier

emilk · 2023-06-15T12:38:30Z

I'm testing this with:

./scripts/build_demo_app.py
(cd web_demo && basic-http-server .)
open http://127.0.0.1:4000/examples/structure_from_motion/

and I get:

[re_viewer::app] re_viewer/src/app.rs:583: data source has left unexpectedly msg.source=http:///examples/structure_from_motion/data.rrd err=Failed to fetch .rrd file from /examples/structure_from_motion/data.rrd: Found an .rrd file from a Rerun version from 0.5.1 or earlier

However, cargo r -p objectron -- --serve works correctly

emilk

Code LGTM (except for wrong error message, see above), but there is something going wrong when testing this (again, see above). I added the do-no-merge label until the testing works.

Also: please update the PR description with the latest (correct) table, and mention the breaking change to the RRD stream format.

jprochazk · 2023-06-15T13:24:08Z

I'm testing this with:

I just tested this and it seems to work for me. The build_demo_app script does not build the SDK, but uses it to render the data files. It seems like that could be the problem here, could you run the SDK build, rm -rf web_demo and then try again?

jprochazk · 2023-06-15T13:31:06Z

The error message of OldRrdVersion is outdated

Updated to say 0.6.0 instead of 0.5.1 - I hope that's the right version

It would be nice with a debug-level log when we reach the end of the HTTP stream. It will make testing the streaming behavior easier

Let's wait for the ehttp release before merging. I will do it momentarily.

…wasm is loading (#2421) ### What Resolves: - #2261 According to the new design, here is how the loading state should work: 1. HTML and CSS loads. It renders the skeleton content without any text. 1. WASM loads. It renders the exact same skeleton content without any text. The user doesn’t notice that the rendering method switched from HTML => WASM. 1. If loading takes long (more than 3 seconds) text fades in and provides additional information. 1. When the App UI is ready, the skeleton content fades away (200ms duration) and the app fades in. The first deployed test of this ended up with 300% progress during the download step, so I've added some extra handling for progress related to compressed streams.At the moment we default to an adhoc compression ratio, but once we land: - #2422 then the progress should be completely accurate again. In order to make all the waiting variants more consistent, this also changes the RRD loading page. The normal waiting page looks like: ![image](https://github.com/rerun-io/rerun/assets/3312232/a8eb2473-7b7c-433a-a0b2-09c6d209c44e) Before: ![image](https://github.com/rerun-io/rerun/assets/3312232/adcf27dc-5c59-4642-8fda-18d0de544442) After: ![image](https://github.com/rerun-io/rerun/assets/3312232/cd4104db-be28-4c32-8171-2b9a9408cf23) This PR does not handle progress indicator during the loading of the RRD itself. The hooks necessary to get access to progress feedback depend on essentially the same work already happening as part of: #2412 and just directly loading the rrd file is generally going to be better than showing a progress indicator. It could be worth revisiting this for things like blueprints with large static data.

…nts - 2023-07-27 (#2842) ## [0.8.0](v0.7.0...v0.8.0) - Infrastructure investments and more transform improvements - 2023-07-27 [Rerun](https://www.rerun.io/) is an easy-to-use visualization toolbox for computer vision and robotics. * Python: `pip install rerun-sdk` * Rust: `cargo add rerun` and `cargo install rerun-cli` * Online demo: <https://demo.rerun.io/version/0.8.0/> ### Overview & Highlights - `log_pinhole` is now easier to use in simple cases and supports non-RDF camera coordinates. [#2614](#2614) - You only need to set focal length and optional principal point instead of setting the full 3x3 matrix. - There is also a new argument: `camera_xyz` for setting the coordinate system. The default is RDF (the old default). This affects the visible camera frustum, how rays are projected when hovering a 2D image, and how depth clouds are projected. - The visualizer can now show coordinate arrows for all affine transforms within the view. [#2577](#2577) - Linestrips and oriented bounding boxes can now be logged via batch APIs in python. - See: `log_linestrips_2d`, `log_linestrips_3d`, [#2822](#2822) and `log_obbs` [#2823](#2823) - Rust users that build their own Viewer applications can now add fully custom Space Views. Find more information [here](https://www.rerun.io/docs/howto/extend-ui#custom-space-views-classes). - New optional `flush_timeout` specifies how long Rerun will wait if a TCP stream is disconnected during a flush. [#2821](#2821) - In Rust, `RecordingStream::connect` now requires `flush_timeout` specified as an `Option<Duration>`. - To keep default behavior, this can be specified using the `rerun::default_flush_time()` helper. - In Python `flush_init_sec` is now an optional argument to `rr.connect()` - In Rust, the `RecordingStream` now offers a stateful time API, similar to the Python APIs. [#2506](#2506) - You can now call `set_time_sequence`, `set_time_seconds`, and `set_time_nanos` directly on the `RecordingStream`, which will set the time for all subsequent logs using that stream. - This can be used as an alternative to the the previous `MsgSender::with_time` APIs. - The Rerun SDK now defaults to 8ms long microbatches instead of 50ms. This makes the default behavior more suitable for use-cases like real-time video feeds. [#2220](#2220) - Check out [the microbatching docs](https://www.rerun.io/docs/reference/sdk-micro-batching) for more information on fine-tuning the micro-batching behavior. - The web viewer now incremental loads `.rrd` files when streaming over HTTP. [#2412](#2412) ![Open Photogrammetry Preview](https://static.rerun.io/9fa26e73a197690e0403cd35f29e31c2941dea36_release_080_photogrammetry_full.png) ### Ongoing Refactors - There have been a number of significant internal changes going on during this release with little visible impact. This work will land across future releases, but is highlighted here since much of it is visible through the changelog. - The layout of the Viewer is now controlled by a Blueprint datastore. In the future this will allow for direct API control of the layout and configuration of the Viewer. A very early prototype of this functionality is available via the `rerun.experimental` module in Python. - An entirely new code-generation framework has been brought online for Rust, Python and C++. This will eventually enable new object-centric APIs with a more scalable, consistent, and ergonomic experience. - Bringup of C++ support is now underway and will eventually become our third officially supported SDK language. ### Known Regressions - Due to the Blueprint storage migration, blueprint persistence on web is currently broken. Will be resolved in: [#2579](#2579) ### In Detail #### 🐍 Python SDK - Clean up warnings printed when `rr.init` hasn't been called [#2209](#2209) - Normalise Python typing syntax to 3.8+ [#2361](#2361) - Simpler, sturdier stateful time tracking in both SDKs [#2506](#2506) - Fix not taking np.array for single colors [#2569](#2569) - Add a basic pyright config [#2610](#2610) - Improve `log_pinhole` and support non-RDF pinholes [#2614](#2614) -
