Solution to failed to acquire username/password from local configuration on rust git libs

Let's say you need to work on a Rust project that depends on other libraries hosted in a private Git repository. This project uses the repository's HTTPS URL. For example:

your-lib = { git = "ssh://git@github.com/your-company/your-lib.git"}

Then you try to start the project and encounter the following error:

$ cargo run

    Blocking waiting for file lock on package cache

    Updating crates.io index

    Updating git repository `https://github.com/your-company/your-lib.git`

error: failed to get `outbox-pattern-processor` as a dependency of package `anti-fraud-service v0.1.0 (/project/your-project)`

  * attempted to find username/password via git's `credential.helper` support, but failed

  if the git CLI succeeds then `net.git-fetch-with-cli` may help here

Caused by:

  failed to acquire username/password from local configuration

The solution is simple. Just edit your global .gitconfig to replace HTTPS URLs with SSH by adding the following lines:

[url "ssh://git@github.com/"]

insteadOf = https://github.com/

What is the best rust lib to post custom metric on datadog?

The best library for recording custom metrics in Datadog using Rust is dogstatsd (https://crates.io/crates/dogstatsd).

The alternative statsd (https://crates.io/crates/statsd) does not allow sending tags. There is even a fork, datadog-statsd (https://crates.io/crates/datadog-statsd), that enables tag sending. However, both define the client without deriving Clone, which prevents using this client as with_state in Axum, resulting in an error similar to this:

the trait bound `...` is not satisfied

Solution to failed to run custom build command for `openssl-sys v0.9.104`

 When upgrading "reqwests" library I got the following error on docker build:

#18 182.8 The following warnings were emitted during compilation:

#18 182.8 

#18 182.8 warning: openssl-sys@0.9.104: Could not find directory of OpenSSL installation, and this `-sys` crate cannot proceed without this knowledge. If OpenSSL is installed and this crate had trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the compilation process. See stderr section below for further information.

#18 182.8 

#18 182.8 error: failed to run custom build command for `openssl-sys v0.9.104`

#18 182.8   --- stdout

#18 182.8   cargo:rustc-check-cfg=cfg(osslconf...

 

Could not find the solution after googling, but I tried the obvious solution, install openssl-dev into the docker image:

FROM rust:1.82-alpine AS builder

RUN apk add --no-cache openssl-dev

After this I got the following error:

x86_64-alpine-linux-musl/bin/ld: cannot find -lssl: No such file or directory

x86_64-alpine-linux-musl/bin/ld: cannot find -lcrypto: No such file or directory

And the fix for this was adding the openssl-libs-static:

FROM rust:1.82-alpine AS builder

RUN apk add --no-cache openssl-dev openssl-libs-static

 

Fixed

Solution to cargo-tarpaulin and missing `GLIBC_2.38' not found

Using cargo-tarpaulin 0.31.4 using binstall on Ubuntu 22.04 may result in errors like the following:

cargo-tarpaulin: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by cargo-tarpaulin)

cargo-tarpaulin: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by cargo-tarpaulin)

I resolved the issue by avoiding binstall. Instead of running: 

I resolved the issue by avoiding binstall. Instead of running

> cargo binstall cargo-tarpaulin

I used the following command:

> cargo insatall cargo-tarpaulin

While this installation method is significantly slower, it successfully resolves the issue.

I suspect similar problems could arise with other Rust libraries when using binstall.
