- Subject: [PATCH 16/16] BUG/MINOR: tools: make str2sa_range() report
- unresolvable addresses
-
- If an environment variable is used in an address, and is not set, it's
- silently considered as ":" or "0.0.0.0:0" which is not correct as it
- can hide environment issues and lead to unexpected behaviours. Let's
- report this case when it happens.
-
- This fix should be backported to 1.5.
- (cherry picked from commit 9f69f46d1f1b1d116c00b4b0483c519747f977b7)
