This bug report will be used to attach some new files and diffs from the IBM
bidi project. They are all under the mozilla/layout directory. Here are the new
files:
? base/public/nsITextFrame.h
? html/base/src/nsBidiFrames.cpp
? html/base/src/nsBidiFrames.h
And here are the files that are being modified:
M base/src/nsBidiPresUtils.cpp
M html/base/src/nsLineLayout.cpp
M html/base/src/nsTextFrame.cpp
Marc, nsITextFrame is the new interface that we discussed a while ago. This
cleans up the somewhat odd subclassing that we reviewed earlier.

I'd suggest changing the use of 'long' to PRInt32 - I'm not used to seeing
non-abstracted types in Layout code! Also, the block that is commented as a
non-BIDI change should either be proven to be incorrect and thus just fixed (eg.
not in an #ifedf IBMBIDI) or have a bug opened on it so we can figure out if it
is wrong and fix it, or correct and clarify why it needs to be the way it is.
I'll do that if you like. sr=attinasi

Just to make sure we are talking about the same thing, Marc, are you referring
to the following block of code?
if (inContentOffset < mContentOffset) //could happen with floaters!
{
result = GetPrevInFlow(outChildFrame);
+#ifdef IBMBIDI // Not a Bidi change; I just thought this line was wrong
+ if (NS_SUCCEEDED(result) && *outChildFrame)
+#else
if (NS_SUCCEEDED(result) && outChildFrame)
+#endif
return (*outChildFrame)->GetChildFrameContainingOffset(inContentOffset,
inHint,
outFrameContentOffset,outChildFrame);

Erik, yes that is the code I was referring to - thanks for checking. Looking at
the full source just now, I cannot see how the old version could be possibly be
correct, so I'd be inclined to just change it with no #ifdef's. Note that
outChildFrame is a **, and every place else that GetPrevInFlow is used, the
check is on the value returned from the method, not on the address of the
returned value (using the word 'return' lightly here to mean an output argument).

Marc: 'long' has the same size as 'void*', while using PRInt32 may be
problematical for a 64-bit platform.

Lina, what size are the things that we are storing inside the void*? Are they
8-bit? In that case PRInt32 or even PRUint8 should be OK, no?
Comment 13•24 years ago

Erik, we'are storing also 'void*' there.
Cannot we replace 'long' by 'PRWord' (defined in prtypes.h)?
(By the way, I'm talking here about the type of the last argument of
GetBidiProperty(); as for the callers of this method, they could safely
use 'PRInt32', indeed, but then need to specify explicitly the size of this
type - sizeof(PRInt32).)

PRWord isn't a good choice either, since it isn't used much in the code base
either. I think we should just use whatever type those things are supposed to
be, e.g. nsBidiLevel, then pass sizeof(nsBidiLevel) to GetBidiProperty().
