I made *all* comments obsolete, since they are. All you need is the simple example that shows the bug in Firefox.
Alice, the reporter suggests that this broke in TB 15.0.1. I don't know whether finding the regression here would help with fixing it. If you have some time, could you look in a regression in Firefox. Please use the attachment which also gives the STR in Firefox.

Alice, thank you so much. I'm impressed and surprised every time you help us. That helps a great deal.
Problem is here: https://dxr.mozilla.org/mozilla-central/rev/6a23526fe5168087d7e4132c0705aefcaed5f571/editor/libeditor/HTMLEditorDataTransfer.cpp#234 IsEditable(targetNode) returns false here, and no pasting takes place. I'm sure that's a consequence of the bug Alice pointed out.
The decision that the target isn't editable is taken here: https://dxr.mozilla.org/mozilla-central/rev/6a23526fe5168087d7e4132c0705aefcaed5f571/editor/libeditor/EditorBase.cpp#3459 And the stack is this: xul.dll!mozilla::IsElementVisible(mozilla::dom::Element * aElement) Line 3459 C++ xul.dll!mozilla::EditorBase::IsEditable(nsINode * aNode) Line 3505 C++ xul.dll!mozilla::HTMLEditor::IsEditable(nsINode * aNode) Line 5255 C++ xul.dll!mozilla::EditorBase::IsEditable(nsIDOMNode * aNode) Line 3490 C++ xul.dll!mozilla::HTMLEditor::DoInsertHTMLWithContext(...)

Boris added that "lazy bit stuff": https://hg.mozilla.org/mozilla-central/rev/efb577526489 Ehsan landed the regressing bug where nsHTMLEditor::IsEditable() was added, now called HTMLEditor::IsEditable(), which calls into nsPlaintextEditor::IsEditable(aNode), now called EditorBase::IsEditable(). https://hg.mozilla.org/mozilla-central/rev/838fb33405ba#l14.37 EditorBase::IsEditable() calls IsElementVisible() that decides that something isn't visible. Boris also signed off on Ehsan's bug. An in the end, all this landed in the lap of Masayuki. Does IsElementVisible() have a bug or shouldn't it be called? I don't know how many people are using "quote as quotation" in webmail using FF, but I could imagine that being a useful feature worth fixing for FF. Help, hints, suggestions welcome.

I forgot to mention: "Paste as quotation" only fails when you try to paste a HTML fragment. If you fill your clipboard with plain text, say from Notepad++, it works since this is a different code path.
Comment 39 and comment 49 together describing when pasting quotation works and when not. works: - pasting plain text clipboard anywhere - pasting html text clipboard directly into body node of the e-mail works not: - pasting html text clipboard into font sub node of body node of the e-mail

Hi, long time, no see ;-) Thanks for the quick feedback. (In reply to :Ehsan Akhgari from comment #51) > What element is passed to IsElementVisible() here? That's a good question that I can answer easily ;-) (although debugging this is a little annoying since this is called an awful lot, so I need to assure to get the right calls triggered from HTMLEditorDataTransfer.cpp#234). When pasting as quotation close to the XXX: blockquote@000000000B3E7EA0 type="cite" state=[40000100000] flags=[01901208] ranges:1 primaryframe=0000000000000000 refcount=9<> Not a surprise since the blockquote is inserted at HTMLEditorDataTransfer.cpp#1653 and then we paste into it. Surely it's empty and not particularly visible (in my layman's opinion). Maybe a fix would be to not check visibility of the element is empty? In comparison, when pasting as quotation close to the YYY: blockquote@00000000098021C0 type="cite" state=[40000100000] flags=[01901208] ranges:1 primaryframe=00000000144A6250 refcount=10<> But this time, IsElementVisible() returns immediately on |if (aElement->GetPrimaryFrame()) {| Oh, check the primary frame in the XXX case, it's null. Do it depends on where you paste whether the blockquote is classified visible or not. If it was inserted into a <font> tag, it's not visible, otherwise it has a primary frame and is visible. Hmm. Would you like me to dump out the ancestors of the blockquote, or at least the parent or do you already have an idea of what's going on here?
Flags: needinfo?(jorgk)
Which "return false" do we take from IsElementVisible, exactly? Does the blockquote ever end up getting a frame?
OK so the question is why does the blockquote node not have the NEEDS_NEW_FRAME flag set on it. Here is what I would expect to happen, please check to see where in this process we go into the weeds: 1. HTMLEditor::PasteAsCitedQuotation() calls DeleteSelectionAndCreateElement() which creates the blockquote and inserts it under its parent in CreateElementTransaction::DoTransaction(). 2. The presshell gets notified about the insertion and tells the frame constructor about it: <http://searchfox.org/mozilla-central/rev/790b2cb423ea1ecb5746722d51633caec9bab95a/layout/base/PresShell.cpp#4334> 3. The frame constructor calls MaybeConstructLazily here: <http://searchfox.org/mozilla-central/rev/790b2cb423ea1ecb5746722d51633caec9bab95a/layout/base/nsCSSFrameConstructor.cpp#7390> 4. The NODE_NEEDS_FRAME flag is set there <http://searchfox.org/mozilla-central/rev/790b2cb423ea1ecb5746722d51633caec9bab95a/layout/base/nsCSSFrameConstructor.cpp#7114>. One possibility is that we're returning early from MaybeConstructLazily here <http://searchfox.org/mozilla-central/rev/790b2cb423ea1ecb5746722d51633caec9bab95a/layout/base/nsCSSFrameConstructor.cpp#7047> because the child is editable (we disable lazy frame construction for editable elements.) But if this happens the frame constructor must be creating a frame for the blockquote element which would make the future call to GetPrimaryFrame() not return null. The element is somehow not getting a frame nor a NODE_NEEDS_FRAME flag which means something in this setup isn't working as expected.
I think I said this in comment #48. This one here: https://dxr.mozilla.org/mozilla-central/rev/6a23526fe5168087d7e4132c0705aefcaed5f571/editor/libeditor/EditorBase.cpp#3459 I'll answer the second question as soon as I understand it, help me ;-)
Sorry, comment #55 was in answer to Boris' question from comment #53.
Ehsan, thanks for the input. Surely I can continue debugging, but perhaps it would be more efficient if you did, unless it's meant as an educational exercise for me ;-) I mean, writing those comments would take more time than looking at it in the debugger yourself, since you know what you're looking for.
> I think I said this in comment #48. This one here: Ah. And cur is the <font> element, I bet? I expect what happens is this: 1) We go to insert the blockquote element (a block). 2) The insertion parent is <font> (an inline with no block kids yet). 3) We get to nsCSSFrameConstructor::ContentRangeInserted. 4) We build the frame construction item list. 5) We do the checks in WipeContainingBlock and discover that IsInlineFrame(aFrame) is true (for the <font>), aItems.AreAllItemsInline() is false (because it contains the <blockquote>), IsFramePartOfIBSplit(aFrame) is false (because it has no block kids yet). So we mark the nearest block ancestor of the <font> as needing frame reconstruction and bail out of the whole thing. So now we have a situation in which the <font> has a frame, the <blockquote> has no frame, there is a pending "reconstruct this whole subtree" on the nearest block ancestor of the <font> that _will_ create a frame for the <blockquote>, and the code in IsElementVisible() is relying on invariants that just don't hold.
In reply to Ehsan's comment #54. Hmm, I have a breakpoint on nsCSSFrameConstructor::ContentAppended(). Pasting the HTML fragment next to the XXX doesn't break there, pasting next to the YYY does. Pasting "plain text" next to the XXX also breaks there. So when pasting doesn't work, nsCSSFrameConstructor::ContentAppended() is not called. Next, I'll answer Boris' question ;-)
If you're going to be answering my question anyway, check whether we end up reaching the "break" statement at http://searchfox.org/mozilla-central/rev/790b2cb423ea1ecb5746722d51633caec9bab95a/layout/base/nsCSSFrameConstructor.cpp#12538 with aFrame->mContent being the <font>?

Attached patch Possible fix (obsolete) — Splinter Review
If Boris' theory is correct (which it looks to be) then I think this patch fixes the bug. Unfortunately I can't test it right now cause I'm on Mac without a mouse with a middle click button, and I don't have the time to convert it into a landable format (with tests and everything), but hopefully this is enough as a starting point for whoever ends up taking this.

Thanks Ehsan, this works, briefly tested with TB. What sort of test would you like? A Mochitest that really tests the paste as quotation into a <font> tag as reported? Or something else? What's your feeling, will the patch break other things? And who's a good reviewer, Masayuki? With those three answers I'll leave you alone (I hope) ;-)
Also working in FF (as expected).
Ehsan, please kindly answer my questions from comment #65: Please describe the test you want in a few words and tell me who should review it. Perhaps Boris for your code patch and you or Masayuki for the test? Could you also please give me a good commit message or is the one I chose OK?

I think a mochitest that pastes as quotation in a <span> would be ideal (since this shouldn't be specific to <font>, any inline element would be similarly affected.) In order to not have to muck with Ctrl+middle click, I suggest just running the cmd_pasteQuote command using SpecialPowers.doCommand(). > What's your feeling, will the patch break other things?

Comment on attachment 8828692 [details] [diff] [review] 795418-paste-as-quotation.patch - fix by Ehsan Hmm, isn't this code supposed to check that the node has a frame, or will have a frame in the future? I don't see why the added bit checks would guarantee that. IIUC, they only say that there is a pending style change: http://searchfox.org/mozilla-central/rev/30fcf167af036aeddf322de44a2fadd370acfd2f/dom/base/Element.h#86-95 so I'm guessing these bits are also set for say a change in 'color', which doesn't imply frame construction.
Attachment #8828692 - Flags: review?(mats) → review-
> Flags: review?(mats@mozilla.com) → review- Oh, what happened to a possible fix just now :-( Where do we go from here?
Perhaps the editor should just flush pending style changes and then check for the presence of frames instead? It seems fragile to try to do editor operations with pending style changes. Alternatively, maybe we could pass aAsyncInsert = false to RecreateFramesForContent from WipeContainingBlock when the insertion parent is editable?
Flags: needinfo?(ehsan)
Here RecreateFramesForContent() is called with REMOVE_FOR_RECONSTRUCTION. This causes us to set reconstruct to true here <http://searchfox.org/mozilla-central/rev/30fcf167af036aeddf322de44a2fadd370acfd2f/layout/base/nsCSSFrameConstructor.cpp#9743> which causes us to post a restyle event here <http://searchfox.org/mozilla-central/rev/30fcf167af036aeddf322de44a2fadd370acfd2f/layout/base/nsCSSFrameConstructor.cpp#9756>. This is where the flag setting happens: <http://searchfox.org/mozilla-central/rev/30fcf167af036aeddf322de44a2fadd370acfd2f/layout/base/RestyleTracker.h#335>. And Mats is right that this can mean either a restyle or a reframe. Perhaps we can also set a special flag there for the nsChangeHint_ReconstructFrame. This should help Jorg or someone else to write a better fix. (In reply to Mats Palmgren (:mats) from comment #73) > Perhaps the editor should just flush pending style changes and then check for > the presence of frames instead? > It seems fragile to try to do editor operations with pending style changes. The IsEditable() function is too popular unfortunately so I think doing that will have performance implications. Most of the editor operations shouldn't depend on the result of reflows, and in the ideal case we finish the editing without flushing and letting only one flush to happen for the next repaint. (Also the editor code has been historically quite unsafe in the face of unexpected flushes.) > Alternatively, maybe we could pass aAsyncInsert = false to > RecreateFramesForContent > from WipeContainingBlock when the insertion parent is editable? Doesn't that force us into the eager frame construction codepath always? That also seems undesirable from a performance perspective...

I meant in one of the callers higher up in the stack in comment 48, e.g. InsertFromTransferable or Paste. This strategy assumes that there are some editor methods that can be considered API entry points where we can insert flush calls. > Most of the editor operations shouldn't > depend on the result of reflows, and in the ideal case we finish the editing > without flushing and letting only one flush to happen for the next repaint. I meant Flush_Frames (a.k.a Flush_Style), not Flush_Layout.

Yes, but only for editable nodes. > That also seems undesirable from a performance perspective... I'd be surprised if either flushing frames or eager frame construction have a noticeable performance impact on the editing operations we're discussing. And it shouldn't affect any non-editable node code paths at all.
Thanks for the comments. How about you suggest a patch? I'm happy to write the test Ehsan described in comment #70, or any other test for that matter. (In reply to :Ehsan Akhgari from comment #74) > This should help Jorg or someone else to write a better fix. I'm really out of my depth here :-(
A mochitest would be much appreciated either way. There are likely tests under editor/libeditor/tests/ that you can crib / extend. I would probably try the "eager frame construction" alternative and see how that performs. Try passing !aFrame->GetContent()->IsEditable() instead of 'true' in the call to RecreateFramesForContent at the end of WipeContainingBlock and see if that fixes this bug?
This works, too. In this case I'm not even able to come up with a commit message since I don't know what you're doing here. If the try works out, can you get a review for it, please. I'll do the test. Try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=a0a58d19eefe9f81e0be45c0288e9a36f9f367c2
This try is 100% green. Please get the patch reviewed and I'll do a test.
So here is a test, which fails without the code patch applied and passes with the code patch applied.

(In reply to :Ehsan Akhgari from comment #86) > Perhaps you want to do this at the end of DeleteSelectionAndCreateElement() > instead as opposed to in all of the callers? It's actually not DeleteSelectionAndCreateElement that needs the frames; it's the code that follows those calls that adds children into the newly added element that requires a frame for an IsEditable check. So from a correctness POV, the flush should be in the caller. (A hypothetical new caller might not need that flush.) That said, these three calls are the only ones in the entire tree, so I guess we could make DeleteSelectionAndCreateElement a private convenience method on HTMLEditorDataTransfer instead, and then it might make sense to make it do the flush for convenience. I don't have a strong opinion either way though, whatever Masayuki-san prefers is fine with me. :-)
Comment on attachment 8829320 [details] [diff] [review] Alternative fix Although, this is pretty hard to review to me. Looks okay, but perhaps, this must not be a perfect solution since this patch won't work if there is a script blocker. But probably, this won't cause new regression for existing add-ons because in such case, FlushFrames() does nothing actually (so, following methods work as current Nightly).

Looks like a pretty straightforward fix with tests. I'm betting the TB folks would like to get this into 52 for their next release, so let's proceed with Aurora/Beta approval requests unless there's a good reason for not doing so.

It's a reasonable low-risk patch, so Aurora uplift seems fine to me. I'm less sure about Beta because there isn't much benefit in this fix for Firefox. If I weigh the risk vs benefit for Firefox only, I wouldn't take it on Beta. OTOH, it does seem worth it for TB though. I'll leave the decision on Beta uplift to others.

Thanks for keeping us in mind. Yes, we'd like this. The fact is, as we did for TB 38 ESR and TB 45 ESR, we'll have a special Thunderbird release branch on mozilla-esr52 and we'll include the patch there. But if it goes onto "main" mozilla-esr52, that would save us a lot of work. Who's filling in the uplift request.

For the risk assessment, let's read the patch author's comment #93 (quote): It's a reasonable low-risk patch, so Aurora uplift seems fine to me. I'm less sure about Beta because there isn't much benefit in this fix for Firefox. If I weigh the risk vs benefit for Firefox only, I wouldn't take it on Beta. OTOH, it does seem worth it for TB though. I'll leave the decision on Beta uplift to others. Indeed there is a good benefit for Thunderbird users. We're early in the cycle, should this "low-risk" patch cause any problems, it can always be backed out. TB will include this fix in TB 52 ESR by using a branch on mozilla-esr52, but of course an uplift to mozilla52 would save the TB release manager (me) a whole lot of work ;-)

Here you go. I tried to land it but I got: abort: push creates new remote head 7831e71bd146 on branch 'COMM2000_20110114_RELBRANCH'! So I'll leave that to you :-)
