[Compare Source](https://redirect.github.com/cyphar/filepath-securejoin/compare/v0.5.0...v0.5.1) ##### Changed - `openat2` can return `-EAGAIN` if it detects a possible attack in certain scenarios (namely if there was a rename or mount while walking a path with a `..` component). While this is necessary to avoid a denial-of-service in the kernel, it does require retry loops in userspace. In previous versions, `pathrs-lite` would retry `openat2` 32 times before returning an error, but we've received user reports that this limit can be hit on systems with very heavy load. In some synthetic benchmarks (testing the worst-case of an attacker doing renames in a tight loop on every core of a 16-core machine) we managed to get a \~3% failure rate in runc. We have improved this situation in two ways: - We have now increased this limit to 128, which should be good enough for most use-cases without becoming a denial-of-service vector (the number of syscalls called by the `O_PATH` resolver in a typical case is within the same ballpark). The same benchmarks show a failure rate of \~0.12% which (while not zero) is probably sufficient for most users. - In addition, we now return a `unix.EAGAIN` error that is bubbled up and can be detected by callers. This means that callers with stricter requirements to avoid spurious errors can choose to do their own infinite `EAGAIN` retry loop (though we would strongly recommend users use time-based deadlines in such retry loops to avoid potentially unbounded denials-of-service). </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

OpenTelemetry-Go
OpenTelemetry-Go is the Go implementation of OpenTelemetry. It provides a set of APIs to directly measure performance and behavior of your software and send this data to observability platforms.
Project Status
| Signal | Status |
|---|---|
| Traces | Stable |
| Metrics | Stable |
| Logs | Beta1 |
Progress and status specific to this repository is tracked in our project boards and milestones.
Project versioning information and stability guarantees can be found in the versioning documentation.
Compatibility
OpenTelemetry-Go ensures compatibility with the current supported versions of the Go language:
Each major Go release is supported until there are two newer major releases. For example, Go 1.5 was supported until the Go 1.7 release, and Go 1.6 was supported until the Go 1.8 release.
For versions of Go that are no longer supported upstream, opentelemetry-go will stop ensuring compatibility with these versions in the following manner:
- A minor release of opentelemetry-go will be made to add support for the new supported release of Go.
- The following minor release of opentelemetry-go will remove compatibility testing for the oldest (now archived upstream) version of Go. This, and future, releases of opentelemetry-go may include features only supported by the currently supported versions of Go.
Currently, this project supports the following environments.
| OS | Go Version | Architecture |
|---|---|---|
| Ubuntu | 1.25 | amd64 |
| Ubuntu | 1.24 | amd64 |
| Ubuntu | 1.25 | 386 |
| Ubuntu | 1.24 | 386 |
| Ubuntu | 1.25 | arm64 |
| Ubuntu | 1.24 | arm64 |

| Windows | 1.25 | amd64 |
| Windows | 1.24 | amd64 |
| Windows | 1.25 | 386 |

While this project should work for other systems, no compatibility guarantees are made for those systems currently.
Getting Started
You can find a getting started guide on opentelemetry.io.
OpenTelemetry's goal is to provide a single set of APIs to capture distributed traces and metrics from your application and send them to an observability platform. This project allows you to do just that for applications written in Go. There are two steps to this process: instrument your application, and configure an exporter.
Instrumentation
To start capturing distributed traces and metric events from your application it first needs to be instrumented. The easiest way to do this is by using an instrumentation library for your code. Be sure to check out the officially supported instrumentation libraries.
If you need to extend the telemetry an instrumentation library provides or want to build your own instrumentation for your application directly you will need to use the Go otel package. The examples are a good way to see some practical uses of this process.
Export
Now that your application is instrumented to collect telemetry, it needs an export pipeline to send that telemetry to an observability platform.
All officially supported exporters for the OpenTelemetry project are contained in the exporters directory.
