For second stage use https://github.com/GoogleCloudPlatform/distroless which provides a minimal image with CA certificates.
Binary is compiled with CGO_ENABLED=0 to prevent dynamical linking to any libraries.
Internal packages are supported by Go 1.5+, any package in /internal/ dir is only importable from the same repo. This will cleanup main dir a bit and provide better namespace for unsee subpackages
This will tell webpack to add a hash to all bundles filenames, we generate script tags for loading those and inject them as templates. No more forced cache bypassing
If I would add a new 'go get foo' line in the build/deps.ok target it wouldn't install anything since the file we touch at the end already exist. Split all 'go get foo' lines into dedicated targets and make build/deps.ok depend on it. This way when you add a new build time dependency make will be able to do the magic and just install what's missing.
I made those change to add github.com/cespare/prettybench, it ended up adding little value so I dropped it, but Makefile refactor still seems like a good idea
Dynamic fingerprints made the code much slower, pprof shows they are responsible for ~70% of all cpu usage for any API call. To make it worse they are applied to all alerts, since dedup layer doesn't know which alerts will be filtered later, it operates on all of them. This PR will:
1. add benchmarks to so it's easier to track performance
2. Keep current methods for accessing fingerprints, but use precomputed static fields in those
3. Refactor Alert methods to use pointers, so we're not working on a copy
Benchmark timing went down from ~4000ns to 0.4ns for fingerprint calls and API response times from 1.3s (for my test sample) to 0.2s, which puts it back to the same level as before moving fingerprints to be dynamic. I still don't like this code much, it's all over the place, but I don't have a good idea how to better structure this, let's hope I'll be wiser in the future.
Fixes#104
@status filter was added to the master branch to support new status key from Alertmanager >=0.6.1
status ended up being nested in Alertmanager (it was added to solve AM issue 609 and that was a long PR with lots of changes), current unsee implementation ended being slightly off with how Alertmanager is naming this, it should actually be @state rather than @status.
Now that Alertmanager provides status=(unprocessed|suppressed|active) in the API it doesn't make sense to keep having separate filters for each value, merge @silenced & @inhibited into a single filter, update docs and UI
This commit turns label checkboxes into multiselect dropdowns that are populated from all labels of all instances of current alert (matched by alertname label). There is also a cocollapsible preview box that allows user to inspect raw silence JSON object we will send to the Alertmanager API. Fixes#69
Drop haml templates in favor of underscore. Haml templates are harder to maintain and require extra dependencies, we already have underscore.js included and it provides a fast templating engine. Rewrite all client side templates using it.
Performance with underscore is pretty much the same as with haml (with 10k alerts).
make vendor-update should update everything inside the vendor dir, to do this 'govendor fetch' needs to be used, current command ('govendor update') is used to copy packages from /home/lukasz/work/go to vendor dir
