chore(deps): Bump github.com/prometheus/client_golang from 1.19.1 to 1.20.5

[dependabot]

Bumps github.com/prometheus/client_golang from 1.19.1 to 1.20.5.

Release notes

Sourced from github.com/prometheus/client_golang's releases.

v1.20.5 / 2024-10-15

We decided to revert the testutil change that made our util functions less error-prone, but created a lot of work for our downstream users. Apologies for the pain! This revert should not cause any major breaking change, even if you already did the work--unless you depend on the exact error message.

Going forward, we plan to reinforce our release testing strategy [1],[2] and deliver an enhanced testutil package/module with more flexible and safer APIs.

Thanks to @​dashpole @​dgrisonnet @​kakkoyun @​ArthurSens @​vesari @​logicalhan @​krajorama @​bwplotka who helped in this patch release! 🤗

Changelog

[BUGFIX] testutil: Reverted #1424; functions using compareMetricFamilies are (again) only failing if filtered metricNames are in the expected input. #1645

v1.20.4

• [BUGFIX] histograms: Fix a possible data race when appending exemplars vs metrics gather. #1623

v1.20.3

• [BUGFIX] histograms: Fix possible data race when appending exemplars. #1608

v1.20.2

• [BUGFIX] promhttp: Unset Content-Encoding header when data is uncompressed. #1596

v1.20.1

This release contains the critical fix for the issue. Thanks to @​geberl, @​CubicrootXYZ, @​zetaab and @​timofurrer for helping us with the investigation!

• [BUGFIX] process-collector: Fixed unregistered descriptor error when using process collector with PedanticRegistry on Linux machines. #1587

v1.20.0

Thanks everyone for contributions!

⚠️ In this release we remove one (broken anyway, given Go runtime changes) metric and add three new (representing GOGC, GOMEMLIMIT and GOMAXPROCS flags) to the default collectors.NewGoCollector() collector. Given its popular usage, expect your binary to expose two additional metric.

Changes

• [CHANGE] ⚠️ go-collector: Remove go_memstat_lookups_total metric which was always 0; Go runtime stopped sharing pointer lookup statistics. #1577
• [FEATURE] ⚠️ go-collector: Add 3 default metrics: go_gc_gogc_percent, go_gc_gomemlimit_bytes and go_sched_gomaxprocs_threads as those are recommended by the Go team. #1559
• [FEATURE] go-collector: Add more information to all metrics' HELP e.g. the exact runtime/metrics sourcing each metric (if relevant). #1568 #1578
• [FEATURE] testutil: Add CollectAndFormat method. #1503
• [FEATURE] histograms: Add support for exemplars in native histograms. #1471
• [FEATURE] promhttp: Add experimental support for zstd on scrape, controlled by the request Accept-Encoding header. #1496
• [FEATURE] api/v1: Add WithLimit parameter to all API methods that supports it. #1544
• [FEATURE] prometheus: Add support for created timestamps in constant histograms and constant summaries. #1537
• [FEATURE] process-collectors: Add network usage metrics: process_network_receive_bytes_total and process_network_transmit_bytes_total. #1555
• [FEATURE] promlint: Add duplicated metric lint rule. #1472
• [BUGFIX] promlint: Relax metric type in name linter rule. #1455
• [BUGFIX] promhttp: Make sure server instrumentation wrapping supports new and future extra responseWriter methods. #1480
• [BUGFIX] testutil: Functions using compareMetricFamilies are now failing if filtered metricNames are not in the input. #1424
