Julius Volz	ed5a0f0abe	promql: Allow per-query contexts. For Weaveworks' Frankenstein, we need to support multitenancy. In Frankenstein, we initially solved this without modifying the promql package at all: we constructed a new promql.Engine for every query and injected a storage implementation into that engine which would be primed to only collect data for a given user. This is problematic to upstream, however. Prometheus assumes that there is only one engine: the query concurrency gate is part of the engine, and the engine contains one central cancellable context to shut down all queries. Also, creating a new engine for every query seems like overkill. Thus, we want to be able to pass per-query contexts into a single engine. This change gets rid of the promql.Engine's built-in base context and allows passing in a per-query context instead. Central cancellation of all queries is still possible by deriving all passed-in contexts from one central one, but this is now the responsibility of the caller. The central query context is now created in main() and passed into the relevant components (web handler / API, rule manager). In a next step, the per-query context would have to be passed to the storage implementation, so that the storage can implement multi-tenancy or other features based on the contextual information.	8 years ago
beorn7	094a098ce6	Revert "Revert the /graph changes." This reverts commit `aa43d34a86`. This brings back the /graph changes so that @grandbora can continue to work on the redirect for backwards compatibility. And other changes can already take the new /graph parameters into account.	8 years ago
beorn7	aa43d34a86	Revert the /graph changes. This revert will be reverted once v1.1 is released and has its own release branch. Since we had already change on top of this, there was no cleaner way of cutting those changes out. This commit reverts the following commits: Revert "Update backend helpers and templates to new url schema" This reverts commit `fc6cdd0611`. Revert "Refactor graph.js" This reverts commit `445fac56e0`. Revert "Use query parameters in the url" This reverts commit `3e18d86d8a`. Revert "Point to correct place for GraphLinkForExpression" This reverts commit `3da825fc76`. Assets are also updated.	8 years ago

beorn7	4b574e8a61	Switch chunk encoding to type 2 where it was hardcoded type 1 before The chunk encoding was hardcoded there because it mostly doesn't matter what encoding is chosen in that test. Since type 1 is battle-hardened enough, I'm switching to type 2 here so that we can catch unexpected problems as a byproduct. My expectation is that the chunk encoding doesn't matter anyway, as said, but then "unexpected problems" contains the word "unexpected".	9 years ago
Brian Brazil	738af32057	template: Use zero-values for missing values. Currently missing values will get the value <no value> rather than the empty string. Using the empty string is more consistent, and should be easier for users to deal with too.	9 years ago
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.	9 years ago
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.	9 years ago

Julius Volz	d868264bb8	Improve UI of /alerts page. Changes to the UI: - "Active Since" timestamps are now human-readable. - Alerting rules are now pretty-printed better. - Labels are no longer just strings, but alert bubbles (like we do on the status page for base labels). - Alert states and target health states are now capitalized in the presentation layer rather than at the source.	10 years ago
