* Add very basic webgl support
* document the default
* only capture rr_dataURL in 2d canvas contexts
* rr_dataURL no longer part of webgl snapshot
* ignore __diff_output__ from jest-image-snapshot
* Rename generic "Monorepo" to "RRWeb Monorepo"
* Serialize WebGL variables
* Move rrweb test port number to unique port
rrweb-snapshot uses 3030, rrweb uses 3031
* Prepare for WebGL2
* Split up canvas replay and record webgl vars
* fix typo
* fix typo part 2
* fix typo
* Handle non-variables too
* provide correct context for warning
* (De)Serialize a lot of different objects
* monorepo root should be the first in the list
* Upgrade puppeteer to 11.x
* Correctly de-serialize webgl variables
* Encode arrayBuffers contents to base64
* rename contents to base64
* add webgl2 support and serialize HTMLImageElements
* Support serializing ImageData
* Correctly classify WebGL2 events
* Serialize format changed
* check if canvas has contents before we save the dataURL
* Remove blank dataURL
* reference original file not type defintion file
* update types
* rename code worspace
* update dependencies
* add spector to inspect webgl
* remove live server settings from code workspace
* Save canvas context in the node
Prevents from saving webgl canvases as 2d dataUrls
* remove extra braces
* add ICanvas type
* use ICanvas from rrweb-snapshot in rrweb instead of OgmentedCanvas
* add snapshots and webgl 2 tests
* Upgrade to puppeteer 12.0.1
* Revert back to puppeteer 9.1.1
* Keep index order consistent between replay and record
* keep correct index order in webgl2
* fixed forgotten import
* buffer up pending canvas mutations
* unify the way webgl and webgl2 get patched
* fix parsing error
* Add types for serialize-args
* Add debugging for webgl replay
* Move start-server to utils
* turn off debug mode by default
* Move pendingCanvasMutations to local object and fix if/else statement
* Always save pending mutations
* only use assert snapshot as it's clearer whats going on
* Ugly fix for now
* Making the tests more DRY
* flush at the end of each request animation frame
* Looks like the promise made this test more predictable
* add waitForRAF
* Make nested iframe recording robust no matter the test speed
* mute noisy error in test
* force a requestAnimationFrame
* Bundle events within one frame together as much as possible
WebGL events need to be bundled together as much as possible so they don't accidentally get split over multiple animation frames.
`newFrame: true` is used to indicate the start of an new animation frame in the recording, and that the event shouldn't be bundled with the previous events.
* Rename RafStamps
* Override event.delay
* cleanup
* Add tests for addDelay
* Add webgl e2e test
* Remove settimeout
* DRY-up test
* Preload images in webgl
* Add e2e test for webgl image preloading
* don't turn on devtools by default!
* Remove spector
* close server after use
* Add imageMap parameter
* Make e2e image test more robust
* document debug mode
* cleanup
* WebGL recording in iframes & Safari 14 support
* fix tests
* don't save null objects as WebGLVar
* group (de)serialized webgl variables by context
* Fix test
* fix tests
* bundle webgl mutations on request animation frame
Instead of fixing it on the replay side we buffer up webgl canvas mutations and wait for a new RAF to flush them. This allows us to remove `newFrame` from the events and simplify things a little
* Add canvas element to mutation observer file
* Add Canvas (Mutation) Manager
Allows you to do `record.freezePage()` and canvas events will get paused.
Based on https://github.com/rrweb-io/rrweb/pull/756#issuecomment-1007566907
* cleanup
* Make sure the correct </body> gets replaced
* Perf: Speed up check to see if canvas is blank
* Access unpatched getImageData
* Use is2DCanvasBlank only for 2d context
* Implemented image restore from rr_dataURL
* Implement saving images in the snapshot
* Fixed image saving, added a test
* Rename data-src to data-rrweb-src
* Updated the guide
* Rename recordImages to inlineImages and try catch
* Hygiene: clean up the xhtml namespace attribute; this is an artefact of the `serializeToString` method which we are using (I think) to be consistent with whitespace and to clean up invalid attributes. I'm removing as was confused as am adding tests related to doctypes
* Record when a document is in `compatMode` and trigger this mode on the iframe upon replay
https://developer.mozilla.org/en-US/docs/Web/API/Document/compatMode
the included DOCTYPE was picked up from https://stackoverflow.com/questions/18976213/ - there may be better ways of triggering compatMode
* Don't write an extra DOCTYPE if there's one already present in the snapshot. Rely instead on whatever doctype is there to trigger the BackCompat mode
* Modify to write the correct doctype if we can sniff xhtml - don't have any evidence that this will make a difference
* Dev convenience: Ignore files generated by editors
* Typo fix
* Was getting a 2000ms timeout on the 'before' hook I believe
* Change certain tests to go directly to their localhost page instead of loading the html content programmatically in order to avoid triggering an incorrect BackCompat mode (incorrect in that the html content has a correct doctype)
* Add test based on motivating site that had images lined up in a square which were all different sizes; very old style percentage width/height attributes were doing the right thing in quirksmode, which is what we are testing for here
* Fixup rrweb test html to include a valid doctype and avoid BackCompat to ensure we're not accidentally testing against quirks modes. I didn't find an elegant way of avoiding the `BackCompat` when adding a minimal iframe, so some BackCompat has slipped in here, I don't think there's much harm
