It's been a busy 2 weeks since the 1.0.0 release and quite a few important PR's have been merged to Loki.
The most significant:
- 1322 rfratto: Fix v1 label API to be Prometheus-compatible
Some might call this a breaking change, we are instead calling it a bug fix as our goal was to be prometheus compatible and we were not 😃
But please be aware if you are using the /loki/api/v1/label or /loki/api/v1/label/<name>/values the JSON result will be different in 1.1.0
Old result:
{
"values": [
"label1",
"label2",
"labeln"
]
}New result:
{
"status": "success",
"data": [
"label1",
"label2",
"labeln"
]
}ALSO IMPORTANT
- 1160 daixiang0: replace gzip with zip
Binaries will now be zipped instead of gzipped as many people voiced their opinion that zip is likely to be installed on more systems by default.
If you had existing automation to download and install binaries this will have to be updated to use zip instead of gzip
Notable Fixes and Improvements
-
Broken version info in startup log message:
1095 pstibrany: Makefile changes to allow easy builds with or without vendoring. Also fixes version bug for both cases.
-
The hashing algorithm used to calculate the hash for a stream was creating hash collisions in some instances.
Please Note this is just one part of the fix and is only in Promtail, the second part for Loki can be tracked in PR1247 which didn't quite make the cut for 1.1.0 and will be in 1.2.0:1254 pstibrany: pkg/promtail/client: Handle fingerprint hash collisions
-
Thank you @putrasattvika for finding and fixing an important bug where logs were some logs were missed in a query shortly after a flush!
1299 putrasattvika: storage: fix missing logs with batched chunk iterator
-
Thank you @danieldabate for helping to again improve our API to be more Prometheus compatible:
1355 danieldabate: HTTP API: Support duration and float formats for step parameter
-
LogQL will support duration formats that are not typically handled by Go like [1d] or [1w]
1357 cyriltovena: Supports same duration format in LogQL as Prometheus
