Package: emacs-snapshot
Version: 1:20060315-1
Severity: normal
When I started a compilation subprocess in this snapshot, Emacs became
soon very slow, next to unusable. Also, the text arriving in the
*compilation* buffer was printed very sluggishly. Running "top"
revealed that Emacs was eating about 90% CPU (the rest was probably
the compilation subprocess). Disabling font-lock-mode for the
*compilation* buffer dropped Emacs' load to a reasonable 2%. I often
run compilations whose buffers can grow to a size of a few dozen
megabytes, but I had never seen something like this before.
The only major change to font-lock in the two weeks since the last
snapshot seems to be the following:
2006-03-14 Alan Mackenzie <[EMAIL PROTECTED]>
* font-core.el: New function/variable
font-lock-extend-region\(-function\)?.
* font-lock.el (font-lock-after-change-function): Call
font-lock-extend-region. Obey font-lock-lines-before.
(font-lock-default-fontify-region): Remove reference to
font-lock-lines-before.
* jit-lock.el (jit-lock-after-change): Call
font-lock-extend-region. Obey font-lock-lines-before.
There has been some discussion on emacs-devel@ between Stefan Monnier
and Alan Mackenzie about these changes, but I don't understand it.
