happy v0.4

Minor Enhancements:

• The test now reports with a v0.4 version bump.

happy v0.3

Features:

• when using -a report the entire CNAME chain of a given service.

Minor Enhancements:

• glibc tends to return PTR entries when AI_CANONNAME flag is set; now using BIND internal calls such as res_search(...) to explicitly ask for CNAME records; and manually parsing the DNS response to circumvent varying AI_CANONNAME behavior across platforms
• updated the test to report all targets even when they do not resolve to an endpoint

happy v0.2

Features:

• added option -a to provide details about the result of the name lookups
• updated the man page with a description of the -a option

happy v0.1

Features:

• added option -b to measure the speed in which HTTP requests are responded to.
• updated the man page with a description of the -b option.

Minor Enhancements:

• updated cmake to properly handle installation of man pages

happy v0.0

Features:

• uses getaddrinfo(...) to resolve service names to endpoints.
• uses non-blocking connect(...) to connect to all endpoints of a service.
• uses a short delay between connection attempts to avoid SYN floods
• the delay between connection attempts is configurable.
• the service name resolution time is not accounted in the output.
• capability to read the input service names list from a file.
• file locking capability when stdout points to a regular file.
• can produce either human-readable or machine-readable output.
• can sort the output for all endpoints for a service name.

Corner cases:

• connection timeouts have status OK and measured times are on the negative scale.
• small negative timeouts indicate a pending error on the socket, SO_ERROR <> 0.
• status is FAIL when happy runs out of socket descriptors.
