Strange error resolving non-existent hostname

[Thomas Klausner <tk%giga.or.at@localhost>]

Hi!

Recently, a mercurial test has started failing for me (7.99.21/amd64):

@@ -80,7 +80,7 @@
   $ echo 'http://does.not.exist/bundle.hg' > server/.hg/clonebundles.manifest
   $ hg clone http://localhost:$HGPORT 404-url
   applying clone bundle from http://does.not.exist/bundle.hg
-  error fetching bundle: * not known (glob)
+  error fetching bundle: No address associated with hostname
   abort: error applying bundle
   (if this error persists, consider contacting the server operator or disable clone bundles via "--config experimental.clonebundles=false")
   [255]

ERROR: test-clonebundles.t output changed


In other words, the test tries resolving does.not.exist and expects
any error message ending with 'not known' but gets the one for
EAI_NODATA, in contrast to all other operating systems (according to
the mercurial author).

Can someone else please try this, to make sure it's not my DNS setup?

cd /usr/pkgsrc/devel/py-mercurial && make test

Any ideas what could be the reason for this?

Thanks,
 Thomas
