Hi there, Here go some good news. Originally I was to send this internally to the core devs, but as we've benefitted from the feedback of active users in the list, and their experiences with the patches (before/afterwards), on the sites they usually browse, it looks like a good idea to do it again. Since June 6, when this thread [1] was started by Sebastian, I've been investigating/working in problems related to it. This led to some extensive rendering tests that catched a laundry list of problems with our current tip (#4643 today). This is a list with brief explanations, taken from the testing data tables I've gathered so far: Problems: 1: overwrites text with images. 2: crops images (aspect ratio). 3: different layout. 4: overwrites text with text float. 5: overwrites text with text. 6: CPU HOG with: tmp.num.html, tmp.num.small.html 7: Missing page sections (sometimes works for the same page). 8: Small images cut in two sometimes ("ESP", "CRO", ...) 9: Wrong aspect ratio for images (text line height) 10: Page drawn with offset (but browser thinks other section is on screen). There're test cases for each one, and most of them were taken and reduced from real pages. Having reduced test cases is good, reduced and isolated tests is better, but the good news is that I have a couple of patches that solve all of them! I'm not saying dillo will be error-free hereafter, but that the root of a whole family of problems has been found and fixed, and this will make future testing much simpler. GROWS2 is the "Grand Redesign Of Widget Sizes" v2 by Sebastian. This is a very powerful and flexible concept whose design allows floats, layers (and absolutes in the future, and more). It has proven very fast so far, even without optimizations. Well the patches are two simple but deep changes in the way markSizeChange() and queueResize() interact. The patch idea is close to graph coverage recursions (with pruning), applied to the widget tree. I'd like to commit it, upload the test suite I'm using, and show the testing data tables I've gathered so everyone can check it with their use cases and report on it. @Sebastian: May I, or would you prefer to review them before? (the patches are the "middle ground" you mentioned. Solve the dw hog problems at dw level, not in the parser, and reuse code you've already seen. A couple of days should be enough to review) @Sebastian: Problem #10 is not related to GROWS2, but a three year old bug discovered during the tests. So let's get it done first. How to reproduce it: Go to [2], wait a bit for most images to load, then use "find text" to find the "re-re" string, scroll a bit downwards to find the image and center it. Go back then forward; no image! But dillo thinks it *is* there so move the cursor to the center of the page and you'll see the hand cursor, wait for the tooltip and drag it a bit downwards to the right. Dillo will repaint from the image data. Bisect shows the bug was introduced by #2863. Attached is a simple concept patch for it. Please review/fix/commit, as I don't know the updated invariants of resize idle. [1] http://lists.dillo.org/pipermail/dillo-dev/2016-June/010887.html [2] http://tinyurl.com/huvf6pn -- Cheers Jorge.-
