Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
github.com/arsham/retry
This library supports Go >= 1.17
.
Retry
calls your function, and if it errors it calls it again with a delay.
Eventually it returns the last error or nil if one call is successful.
l := &retry.Retry{
Attempts: 666,
Delay: time.Millisecond,
}
err := l.Do(func() error {
// do some work.
return nil
})
You can provide multiple functions:
err := l.Do(func() error {
return nil
}, func() error {
return nil
}}
If you want to stop retrying you can return a special error:
err := l.Do(func() error {
if specialCase {
return &retry.StopError{
Err: errors.New("a special stop"),
}
}
return nil
})
The standard behaviour is to delay the amount you set. You can pass any function with this signature to change the delay behaviour:
func(attempt int, delay time.Duration) time.Duration
You can also pass the retry.IncrementalDelay
function that would increase the
delay with a jitter to prevent Thundering
herd.
l := &retry.Retry{
Attempts: 666,
Delay: 10 * time.Millisecond,
Method: retry.IncrementalDelay,
}
err := l.Do(func() error {
if specialCase {
return &retry.StopError{
Err: errors.New("a special stop"),
}
}
return nil
})

Floating dependency ranges in npm can introduce instability and security risks into your project by allowing unverified or incompatible versions to be installed automatically, leading to unpredictable behavior and potential conflicts.

A new Rust RFC proposes "Trusted Publishing" for Crates.io, introducing short-lived access tokens via OIDC to improve security and reduce risks associated with long-lived API tokens.
