In the past, commita231cb27("iotests: Fix 104 for NBD", v2.3.0) added an additional filter to _filter_img_info to rewrite NBD URIs into the expected output form. This recently broke when we tweaked tests to run in a per-format directory, which did not match the regex, because _img_info itself is now already changing SOCK_DIR=/tmp/tmpphjfbphd/raw-nbd-104 into /tmp/tmpphjfbphd/IMGFMT-nbd-104 prior to _img_info_filter getting a chance to further filter things. While diagnosing the problem, I also noticed some filter lines rendered completely useless by a typo when we switched from TCP to Unix sockets for NBD (in shell, '\\+' is different from "\\+" (one gives two backslash to the regex, matching the literal 2-byte sequence <\+> after a single digit; the other gives one backslash to the regex, as the metacharacter \+ to match one or more of <[0-9]>); since the literal string <nbd://127.0.0.1:0\+> is not a valid URI, that regex hasn't been matching anything for years so it is fine to just drop it rather than fix the typo. Fixes:f3923a72("iotests: Switch nbd tests to use Unix rather than TCP", v4.2.0) Fixes:5ba7db09("iotests: always use a unique sub-directory per test", v8.0.0) Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20230519150216.2599189-1-eblake@redhat.com> Reviewed-by: Daniel P.
