bower depends on loopback? #99

Closed craftyguy closed 2 years ago

craftyguy commented 2 years ago

I'm trying to run bower in a new network namespace (on Linux) that does not have any network interfaces or connectivity at all (so, no lo, etc), and bower seems to have a hard requirement on that:

$ bower
Errors in configuration file:
posix_spawn failed
sendto(6, "\253&\1\0\0\1\0\0\0\0\0\0\10librem14\0\0\1\0\1", 26, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.1")}, 16) = 26
sendto(6, "\2542\1\0\0\1\0\0\0\0\0\0\10librem14\0\0\34\0\1", 26, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.1")}, 16) = 26
poll([{fd=6, events=POLLIN}], 1, 2500)  = 0 (Timeout)

The only reference to any network connection requirement is a brief mention of bower using ssh to access a remote notmuch. Is there a way to disable this and run bower completely "offline" ?

wangp commented 2 years ago

This would be due to the call to getaddrinfo in get_hostname_fqdn, which is used to determine the right side of Message-IDs (xxxx@yyyy) of any messages we create. I think there might be privacy implications of revealing the hostname or FQDN anyway, so we could just take the domain name from the From address. EDIT: that's on the message-id-domain branch now

The "posix_spawn failed" error is strange though.

craftyguy commented 2 years ago

ah yeah seems like the posix_spawn failed is unrelated, I no longer get timeouts on that message-id-domain branch. So I think the original issue I reported is resolved, thanks!

I totally don't expect you to support this way of running bower (using namespaces to constrain it), so feel free to ignore this... but if you're curious...

here's the strace (using the branch above):
