Segmentation fault if HOME not set

[koebi001]

Version:

1.2.5-1 from debian bookworm

What is happening:

If HOME is not set I am getting a Segmentation fault.
I am using it in a bash script which I execute using salt-stack therefore the environmen does not contain what someone would expect to be always set.
My command looks like this:

httpdirfs --cache --cache-location /tmp/httpdirfs --single-file-mode  https://webserver/file /mnt/file

What do I expect:

Write an error message to stderr and exit whit exit status != 0

Workaround:

Set HOME before running httpdirfs
For example:

HOME=/tmp httpdirfs --cache --cache-location /tmp/httpdirfs --single-file-mode  https://webserver/file /mnt/file

That's understandable. I never expected people to use this without a home directory... I will fix this eventually. Feel free to submit a patch though!

I just want to add that the root cause of this problem is this:

httpdirfs/src/cache.c

	if (!xdg_cache_home) {
	char *home = getenv("HOME");
	char *xdg_cache_home_default = "/.cache";
	xdg_cache_home = path_append(home, xdg_cache_home_default);
	}
