Package: anything-el
Version: 1.287-2.1
Severity: critical
Problem description
-------------------
If for some unknown reason an emacs file lock of the file
`~/.emacsd/anything-c-adaptive-history` existing, batch
operation of emacs will never be finished.
Reproducing the lock issue
--------------------------
I don't know what has cause the stale lock on my machine, but it can be easily
recreated as described below.
```
pkill emacs # ensure that emacs is not running
cd /root/.emacs.d
ln -s ${USER}@${HOSTNAME}.${DOMAIN}.5423:1487632643
.#anything-c-adaptive-history
```
Resulting problems
-------------------
Now start emacs. Everything seems to be fine, but on quitting emacs you will
see the question concerning the lock
waiting for any user input.
This seems in normal cases a minor malaise, but the impact if emacs is used for
batch processing.
Please try the following with and without the stale lock.
`emacs --no-init-file --batch`
Without the stale lock this command will finish after a short time.
With the lock, you will see the following output:

At this point the emacs is hanging.
Trying to answer the „lock“ prompt is not possible. You have to terminate the
processing *SIGINT* (Ctrl+C) or killing it.
Why is this bug critical?
-------------------------
This bug report is related to bug #886024 – which describes how an unexpected
problem like this renders debian package
installation unusable.
