24.3.50; `put-text-property' creates lock files for indirect buffer despite `with-silent-modifications' |
|
Date: |
Wed, 27 Feb 2013 21:36:25 +0400 |
1. Open a file that has some syntax highlighting in the associated mode
(e.g. ~/test.js, in js-mode).
2. (switch-to-buffer (make-indirect-buffer (current-buffer) "foo"))
3. M-x js-mode
4. Observe the created .#test.js symlink.
* (buffer-modified-p) returns nil in both buffers.
* The lock file won't be removed when the indirect and the base buffer
are killed, and even after Emacs is killed.
* If I remove the lock file manually, it will be re-created each time
`put-text-property' is called.
* Possibly related to Bug#3038.
* Reproduces in 24.2 and 23.4, so not a regression, as far as 24.3 is
concerned.
Here's a typical Lisp-level backtrace:

(Same thing happens inside `syntax-propertize', so it's not just jit-lock).

I'm unable to reproduce this bug in Emacs 27. Instead I get (when
saying `M-x js-mode'):
---
Not enabling jit-lock: it does not work in indirect buffer
---
So has this been fixed by now or is this just some... other thing?
Thanks for looking into this.
Seems fixed to me as well. Actually can't reproduce going as far back as
Emacs 25 (even by calling put-text-property inside
with-silent-modifications manually). So, closing.
