Description

using version 1.4.37
i would expected last item to override previous one, but result is quite unexpected, the alias does not work at all (files aren't taken from neither mapped paths).

# cat /tmp/julla.conf
alias.url += (
    "/jquery/" => "/usr/share/jquery/",
)
alias.url += (
        "/jquery/" => "/www/htdocs/cdn-js/legacy/current/dist/jquery/",
)

# lighttpd -pf /tmp/julla.conf
config {
    var.PID        = 2368
    var.CWD        = "/etc/lighttpd/webapps.d" 
    alias.url      = (
        "/jquery/" => "/usr/share/jquery/, /www/htdocs/cdn-js/legacy/current/dist/jquery/",
    )
    server.modules = ("mod_indexfile", "mod_dirlisting", "mod_staticfile")

}

That is the way "+" has been implemented on arrays (it doesn't know anything about the context of "alias.url"); I'm not going to change that.

Submitted pull request https://github.com/lighttpd/lighttpd1.4/pull/28 to issue warning and ignore duplicate keys when merging arrays (for arrays without auto-generated keys). Please reopen this issue and review the patch in the pull request.

FYI: it appears this issue was addressed in the 1.5.x branch back in 2005.

r267 is not the same problem, and was also applied in 1.4.x.

I modified the patch to throw an error; I don't see any sane semantics in ignoring the entry in the second array while still showing a warning (usually you would expect the second array to overwrite entries in the first).
