When running a font-inflation related reftest we also unset the font inflation related prefs that were specified in the reftest.list file. This causes font-inflation to go from enabled to disabled and we detect that for the first time while reflowing the scroll frame. Instead we should reflow when any pref that could affect font inflation is changed. I scanned the font-inflation code in PresShell and Document::GetViewportInfo for prefs are consulted, but I didn't go a super exhaustive search.

The test fixes all fell into the follow categories: A) The test uses requestAnimationFrame to wait one frame and expects scrolling to be complete. With the desktop zooming scrollbars in order for the scrolling to show up on the main thread we need to send the scroll request to the compositor and then hear back from it via an apz repaint request (apz callback helper). Waiting on requestAnimationFrame will complete the first part, but not necessarily the second part. The fix is to wait for a scroll event. B) Switching tests to wait for scroll events exposes another problem: the test can do things that cause a scroll in order to setup the test (and that may not be obvious that it causes a scroll) before actually proceeding to do the test and do something that causes a scroll and then checks for the scroll change of the second thing. Waiting for a requestAnimationFrame would include both those scrolls without desktop zooming scrollbars, but if we wait for a scroll event we will get the scroll event for the first thing which we are not interested in. So we need to make sure scroll events are cleared out before waiting for any scroll events. We do this by waiting two requestAnimationFrame's and waiting for apz to be flushed. We also use this when a test does something and it wants to test that scrolling is not performed. The main thing that causes scrolling that may not be obvious: calling node.focus().

advanceTimeAndRefresh/restoreNormalRefresh and expect scrolling to be done after a call to advanceTimeAndRefresh. This is basically A), advanceTimeAndRefresh does a refresh driver tick but doesn't allow a repaint request to come back to the main thread.

When running a font-inflation related reftest we also unset the font inflation related prefs that were specified in the reftest.list file. This causes font-inflation to go from enabled to disabled and we detect that for the first time while reflowing the scroll frame. Instead we should reflow when any pref that could affect font inflation is changed. I scanned the font-inflation code in PresShell and Document::GetViewportInfo for prefs are consulted, but I didn't go a super exhaustive search.

…for each insn. r=nbp. Currently IONFLAGS=codegen doesn't show the assembler offset on any target, AFAIK. On arm64, at least, reasoning about code offsets merely by looking at the log output is unreliable, because it is impossible to spot "holes" (multiple 4-byte insn slots) in the output, and also it is impossible to see where there has been a transition to a new assembler instance. This patch fixes it in the obvious way, by printing the offset as 6 hex digits.

This adds a variation of each existing test using the refactored code path. Tests are initialized twice, once for legacy and refactored path each, to strike a balance between file name length and descriptiveness.

Upstream commit: https://webrtc.googlesource.com/src/+/a93f581705787105ac28bccdc179778fd4400298 dcsctp: Don't generate FORWARD-TSN across stream resets This was a fun bug which proved to be challenging to find a good solution for. The issue comes from the combination of partial reliability and stream resetting, which are covered in different RFCs, and where they don't refer to each other... Stream resetting (RFC 6525) is used in WebRTC for closing a Data Channel, and is done by signaling to the receiver that the stream sequence number (SSN) should be set to zero (0) at some time. Partial reliability (RFC 3758) - and expiring messages that will not be retransmitted - is done by signaling that the SSN should be set to a certain value at a certain TSN, as the messages up until the provided SSN are not to be expected to be sent again. As these two functionalities both work by signaling to the receiver what the next expected SSN should be, they need to do it correctly not to overwrite each others' intent. And here was the bug. An example scenario where this caused issues, where we are Z (the receiver), getting packets from the sender (A): 5 A->Z DATA (TSN=30, B, SID=2, SSN=0) 6 Z->A SACK (Ack=30) 7 A->Z DATA (TSN=31, E, SID=2, SSN=0) 8 A->Z RE_CONFIG (REQ=30, TSN=31, SID=2) 9 Z->A RE_CONFIG (RESP=30, Performed) 10 Z->A SACK (Ack=31) 11 A->Z DATA (TSN=32, SID=1) 12 A->Z FORWARD_TSN (TSN=32, SID=2, SSN=0) Let's assume that the path Z->A had packet loss and A never really received our responses (#6, #9, #10) in time. At #5, Z receives a DATA fragment, which it acks, and at #7 the end of that message. The stream is then reset (#8) which it signals that it was performed (#9) and acked (#10), and data on another stream (2) was received (#11). Since A hasn't received any ACKS yet, and those chunks on SID=2 all expired, A sends a FORWARD-TSN saying that "Skip to TSN=32, and don't expect SID=2, SSN=0". That makes the receiver expect the SSN on SID=2 to be SSN=1 next time at TSN=32. But that's not good at all - A reset the stream at #8 and will want to send the next message on SID=2 using SSN=0 - not 1. The FORWARD-TSN clearly can't have a TSN that is beyond the stream reset TSN for that stream. This is just one example - combining stream resetting and partial reliability, together with a lossy network, and different variants of this can occur, which results in the receiver possibly not delivering packets because it expects a different SSN than the one the sender is later using. So this CL adds "breakpoints" to how far a FORWARD-TSN can stretch. It will simply not cross any Stream Reset last assigned TSNs, and only when a receiver has acked that all TSNs up till the Stream Reset last assigned TSN has been received, it will proceed expiring chunks after that.

But we do have a pres-shell, and nsFrameLoader::Show just early-returns then, and thus we end up with a detached pres shell which is not hooked to the view tree and thus not painted... So there are multiple potential fixes. First (this is the approach this patch takes): * Make nsHideViewer not fail to hide a presentation when the frame loader has changed. This is not an issue per se, but leaves stale views / etc living for too long which is not nice. * Fix up the Show() code path to handle this case properly by parenting the pres-shell and initializing the docshell properly. Second potential fix would be to store the temporary state somewhere else than the frame loader (like the element). This may be a less invasive change somehow, but it looks pretty fishy to me, and not particularly better... Terribly sorry about the lack of test-case, but this is racy as crazy and I had a lot of trouble to even reproduce it in a debug build. This needs the PresShell creation for the subdocument to happen right after setting .data on the <object>, but before processing its reframe. Differential Revision: https://phabricator.services.mozilla.com/D69487

There are three parts to this patch: 1. When we're building the exit frame, instead of moving both the SP and the PSP for every push, we move the SP all at once. This lets us eliminate 3 instructions. 2. The syncStackPtr in callWithABIPre is redundant with the syncStackPtr in call. Removing it eliminates another instruction. 3. Prior to this patch, the VM wrapper epilogue looked like this: ``` mov x28, x29 // restore fp to psp mov sp, x28 A // sync sp ldr x29, [x28], #8 // restore saved fp to fp ldr x16, [x28], #32 // load return address into x16 mov sp, x28 B // sync sp ret x16 // return to x16 ``` Instructions A and B look redundant. In my first version of this patch, I removed B. However, the two ldr instructions actually do a post-index modification of the PSP, so that version of the patch left SP and PSP unsynchronized when returning from the VM wrapper. Oddly, that version of the patch still passed all jit-tests. It seems much safer, though, to just remove A instead. In total, this removes 5 instructions from each VM wrapper. There is still some room for improvement around passing arguments: we emit a sync after we finish passing arguments, even if we aren't passing anything on the stack. In theory we could also allocate space for stack arguments while we're building the exit frame, but that would involve duplicating much more of the argument passing code.
