juliusv fd4a7b885b Merge pull request #427 from prometheus/retrieval-rename-address-url 
Rename Address to URL
 2014-12-18 13:27:42 +01:00
Johannes 'fish' Ziemke ff95a52b0f Rename Address to URL 
The "Address" is actually a URL which may contain username and
password. Calling this Address is misleading so we rename it.

Julius Volz 00a2a93a05 Add regression tests for metrics mutations in AST. 
It turned out in the end, that only drop_common_metrics() produced any
erroneous output in the old system. The second expression in the test
("sum(testmetric) keeping_extra") already worked in the old code, but
why not keep it in...

The way to test ranged evaluations is a bit clumsy so far, so I want to
build a nicer test framework in the end, where all the test cases can be
specified as text files which specify desired inputs, outputs, query
step widths, etc.

Bjoern Rabenstein b1e4956142 Apply a giant code cleanup. 
Essentially:

- Remove unused code.

- Make it 'go vet' clean. The only remaining warnings are in generated code.

- Make it 'golint' clean. The only remaining warnings are in gerenated code.

- Smoothed out same minor things.
