18465 2008-04-13 13:32:14 -0700 wxWebit crash in BitmapImage::draw on particular site 2008-05-28 11:38:01 -0700 1 1 1 Unclassified WebKit WebKit wx 528+ (Nightly build) PC Windows XP RESOLVED FIXED P2 Major --- 1 avasilev kevino avasilev kevino oldest_to_newest 77412 0 avasilev 2008-04-13 13:32:14 -0700 Opening the site 'dir.bg' in wxBrowser, after it is completely loaded (tha statusbar says 'Load complete', then starting to resize increasing the size of the window - at one point the application crashes with access violation. I am in the process of investigating hte bug, but seems gdb provides some misleading information about the point of the crash, or I have not figured out something yet. 77436 1 20510 avasilev 2008-04-13 18:31:14 -0700 Created attachment 20510 patch The problem is that the source and destination areas are not always the same sizes, and without a check the underlying wx Blit code crashes. This is why I jsut added a simple check and if the sizes dont match hte function quits. This is just to prevent a crash, I am not sure how is it specified in the call how exactly to handle stretching or tiling of the image to fit the destination rect. 77437 2 20510 hyatt 2008-04-13 18:41:20 -0700 Comment on attachment 20510 patch I think you probably just need to add a null check for your underlying platform image (like Mac has). I recently removed the cross-platform null checks from draw and drawTiled, so it's up to the platforms to null-check now. 77442 3 kevino 2008-04-13 19:28:47 -0700 @Hyatt, we do check for a NULL image when we call frameAtIndex, so we shouldn't be hitting this point in the code without a valid image. @Alexander, I'll prepare some code to resize images as we need that anyway, but we've never hit a crash before just because the src and dest rect were different, and I have so far been unable to reproduce your crash. Since I don't have MinGW setup, I would really appreciate if you could attach the stack traces for these crashes (this and the mouse one too) so I can look at the code paths that lead to these crashes. 77539 4 20528 avasilev 2008-04-14 05:11:23 -0700 Created attachment 20528 patch to ImageWx.cpp This patch adds support for image rescaling in the draw method, as well as filling with solid color when source is 1x1 pixel 77542 5 avasilev 2008-04-14 05:26:53 -0700 @Hyatt: Yes, the images are checked and they aren't null, we have valid images when the crash happens. @Kevin: The crash with the 'dir.bg' site occurred also with msvc, in exactly the same way. I have dug deeply in wxWidgets to find the cause - it was because of the Blit code trying to read the source image past its end - wxWidgets assumes that the source and destination are of the same size and does not perform any checks on this. As for the image resize, I just committed a patch and then read your reply that you are going to do the same - I'm not sure my variant of rescaling is very efficient, but this seems to be the only way to rescale image - by converting to wxImage and then back to wxBitmap, the doc says the only other way is to blit between wxMemoryDC-s but i didn't find out any resizing support special for wxMemoryDC, so I used the canonical way via wxImage. Since I have changed the original files, and now the crashes don't occur, I will do a build on the original source tree and send you the traces 77549 6 avasilev 2008-04-14 06:28:59 -0700 Kevin, here are the stack traces for both crashes: Image crash: Program received signal SIGSEGV, Segmentation fault.
