Hi,
More bugs are being reported recently, and none of the old ones have
been fixed. Thus, we are moving in the wrong direction.
Showstoppers without hope:
- Selection with the mouse. Does not work in math nor in tables. It kind
of works in insets, although problems have been reported with this as
well. To reproduce, make a formula or a table, type some text and try to
select it with the mouse. We need a volunteer to investigate this.
- Crashes with multiple windows open. It seems that Buffer contains Rows
of paragraphs, and this is no good in a multiple view setting. Options:
a) Rework Buffer to not have Rows (big change, risky), b) Disable
multiple views completely for now, c) Disable multiple views of same
document only. Seems to me option C would be safe and still provide some
benefit to the user.
- Cursor trouble: Full refresh on each blink. Abdel says it's a lot of
work to fix this without the pixamp. Options a) Spend that time, b)
Revert to old painting scheme. Given that the removal of the pixmap did
not give us any noticable speed-up, I think we should revert this change
which was done the last Monday of the meeting.
Showstoppers with hope:
- In math the cursor blinks at the start of the math inset and then
seems to go the correct place afterwards. I suggest that Peter's patch
which disables immediate cursor updates is applied, unless someone can
track down the bug in the math code.
Other problems without hope:
- Mac is unusable because of poor performance, among other things.
Options: a) Revert commit from 14th of July which disabled partial
refresh. This is a little dangerous, since it is known that this might
cause invalid coord cache entries. b) Do a), but also implement partial
coord cache refresh to make it safe. c) Implement a caching painting
scheme, such that only changed paint requests are done.
- No UTF-8 support in LaTeX export.
- Nice icons in change tracking missing.
Other problems with hope:
- Copy/paste using middle mouse button inserts musical notes.
- Branches are not unicode clean. Reported by Helge.
- URLs in documents causes LaTeX error. Reported by Helge.
Change tracking is being worked on, and will be done before the 14th.
The tab bar work is settling down. I think all other pending patches
have all been applied, but it's difficult to keep track off.
We have a bunch of problems without any hope. At the same time, people
are getting too busy to work on LyX.
So, the future does not look too bright for LyX. In other words, we are
back in deep shit again.
Therefore, I would suggest to freeze the code even more until progress
has been made on the hopeless showstoppers. We have some difficult
problems to solve, and those will require a concentrated effort to nail.
The positive side to this is that each person who conquers a hopeless
showstopper is instantly a hero.
Regards,
Asger
