Bug #7311: DRb test suite fails when hostname cannot be reached

I have set following hostname:

 $ hostname
 dhcp-25-70

However, it cannot be reached:

 $ ping `hostname`
 PING dhcp-25-70 (10.34.25.70) 56(84) bytes of data.

This causes that the DRb test suite fails:

So there are two possible ways how to fix this issue.

(1) Enforce usage of localhost in test suite (0001-Enforce-localhost-for-DRb-tests.patch). Unfortunately it appears it does not solve my issues completely under some (not so clear) circumstances.
(2) Detect if hostname is associated with some IP address of my computer, otherwise fallback to localhost (0001-Fallback-to-localhost-if-hostname-is-not-associated-.patch). This resolves my issue completely.


BTW this test error later causes deadlock in TestProcess test suite [1], which is nasty :/

 TestDRbYield#test_05_array_subclass = 3.01 s = E
 TestDRbYield#test_06_taint = 3.01 s = E

So there are two possible ways how to fix this issue.

(1) Enforce usage of localhost in test suite (0001-Enforce-localhost-for-DRb-tests.patch). Unfortunately it appears it does not solve my issues completely under some (not so clear) circumstances.
(2) Detect if hostname is associated with some IP address of my computer, otherwise fallback to localhost (0001-Fallback-to-localhost-if-hostname-is-not-associated-.patch). This resolves my issue completely.


BTW this test error later causes deadlock in TestProcess test suite [1], which is nasty :/

[ruby-core:52501] [ruby-trunk - Bug #7311] DRb test suite fails when hostname cannot be reached

[vo.x (Vit Ondruch)]

Issue #7311 has been updated by vo.x (Vit Ondruch).


It is not just test suite issue. See 0001-Fallback-to-localhost-if-hostname-is-not-associated-.patch

Although it is pretty minor issue, due to other bugs in Gnome 3, it forces me to reboot quite often :/ But anyway, it is not blocker.

So there are two possible ways how to fix this issue.

(1) Enforce usage of localhost in test suite (0001-Enforce-localhost-for-DRb-tests.patch). Unfortunately it appears it does not solve my issues completely under some (not so clear) circumstances.
(2) Detect if hostname is associated with some IP address of my computer, otherwise fallback to localhost (0001-Fallback-to-localhost-if-hostname-is-not-associated-.patch). This resolves my issue completely.


BTW this test error later causes deadlock in TestProcess test suite [1], which is nasty :/

I don't like the patch, maybe seki-san can review it.

[ruby-core:94364] [Ruby master Bug#7311] DRb test suite fails when hostname cannot be reached

[merch-redmine]

Issue #7311 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Assigned to Closed

I also think the `0001-Fallback-to-localhost-if-hostname-is-not-associated-.patch` is a bad approach.  We should not force localhost if the hostname given is not associated with an IP address.  That sounds like a issue that should be reported to the user via an exception.
