Brian Brazil ce7f31e03c promql: Bump sleep in query timeout test 
This test is flaky, I'm presuming the time.AfterFunc
call is being delayed so the evaluation isn't getting
cancelled.

Julius Volz af513468eb Fix some dead code, missing error checks, shadowings. 
I applied
https://medium.com/@jgautheron/quality-pipeline-for-go-projects-497e34d6567
and was greeted with a deluge of warnings, most of which were not
applicable or really fixable realistically. These are some of the first
ones I decided to fix.

Fabian Reinartz a1617d90f4 Merge pull request #1073 from prometheus/whats-our-vector-victor 
promql: Add vector function.

Brian Brazil 69f5fa0c1e promql: Add vector function. 
Currently the only way to convert a scalar to a vector is to
use absent(), which isn't very clean. This adds a vector()
function that's the inverse of scalar() and lets your optionally
set labels.

Example usage would be
vector(time() % 86400) < 3600
to filter to only the first hour of the day.

Brian Brazil 9ec11b1847 Merge pull request #1049 from prometheus/bool-nofilter 
promql: Add 'bool' modifier to comparison functions
 2015-09-03 15:08:38 +01:00
Brian Brazil 29e8dc2c49 promql: Add 'bool' modifier to comparison functions 
When doing comparison operations on vectors, filtering
sometimes gets in the way and you have to go to a fair bit of
effort to workaround it in order to always return a result.
The 'bool' modifier instead of filtering returns 0/1 depending
on the result of the compairson.

This is also a prerequisite to removing plain scalar/scalar comparisons,
as it maintains the current behaviour under a new syntax.

Julius Volz 61c42c8da0 Change relabel_replace() to do full-string matches. 
THIS IS A BREAKING CHANGE.

Fix "go vet" errors.
 2015-08-26 12:50:18 +02:00
Julius Volz 995d3b831d Fix most golint warnings. 
This is with `golint -min_confidence=0.5`.

I left several lint warnings untouched because they were either
incorrect or I felt it was better not to change them at the moment.
 2015-08-26 12:44:46 +02:00
Julius Volz 963ad82dcb Fix "go vet" errors. 
I ignored all errors of the type "composite literal uses unkeyed
fields". Most of them are wrong because of
https://github.com/golang/go/issues/9171.

Brian Brazil fb585e4591 promql: Remove interpolation of vector values. 
The current behaviour produces values that are not
from rules or scrapes. So if for example I have
a boolean 0/1 it can be returned as 0.2344589. This
prevents a number of advanced use cases, introduces
race conditions and can produce misleading graphs.

Brian Brazil e6a67476c2 rules: Allow recorded rules expressions to be scalars. 
This is useful if you want to build up a constant metric,
such as a set of alert thresholds that vary by label value.

Fabian Reinartz 690b5f1575 Remove multi-statement queries 
This commit removes the possibility to have multi-statement queries
which had no full support anyway. This makes the caller responsible
for multi-statement semantics.
Multiple tests are no longer timing-dependent.

Brian Brazil d6a80c2b76 promql: Add support for predict_linear(my_timeseries[1h], 7200)

based on the last hour of data.

Fabian Reinartz 5b91ea9b36 storage: improve label matching and allow unset matching. 
Matching of empty labels now also matches metrics where the label
was not explicitly set to the empty string.

Fabian Reinartz fe301d7946 promql: remove global flags 2015-06-15 19:01:06 +02:00
Julius Volz 5e2d1c1464 Deprecate keeping_extra, rename it to keep_common. 
`keep_common` is more in line with the function name
`drop_common_labels()` terminology-wise, and also more in line with
`group_left`/`group_right` (no `...ing` verb suffix).

We could also go the full way and call it `keep_common_labels`. That
would have the benefit of being even more consistent with the function
`drop_common_labels()` and would be more explanatory, but it also seems
quite long.
