When visiting a file with tramp and killing text with xclip-mode
enabled, the text gets sent to the kill-ring but the X clipboard does
not get set. Additionally, the xclip shell process does not close.
Steps to reproduce:
- Ensure xclip is installed (In the shell: `which xclip`)
- Install xclip Emacs package
- Set variables `x-select-enable-clipboard` and/or `x-select-enable-primary` to `t`.
- Enable xclip (`M-x xclip-mode RET`)
- Visit a file using tramp (eg. `/sudo:user@localhost:/tmp/tramp-file`)
- Type some text
- Select a region and kill it
Expected behaviour
- Selected text gets sent to the kill-ring and X clipboard or primary
buffer (this can be verified in the shell with `xclip -o -selection primary` and/or
`xclip -o -selection clipboard`.
- xclip processes exit cleanly
Observed behaviour
- Selected text gets sent to the kill-ring, but not the X clipboard or
primary buffers.
- xclip processes do not terminate (user is warned that they are still
running when exiting Emacs).
- Further, yanking text at this point causes the contents of the X
clipboard or primary buffer to be inserted at the tip of the
kill-ring so that gets yanked instead of the killed text.
Workarounds
As suggested in Emacs StackExchange by user Stefan
`start-file-process` with `start-process` in a copy of the xclip 1.4
source fixes this particular issue though whether this causes any
unwanted side effects has not been extensively tested.
