Validation

To help validate the integrity of the update I have created the following bash script that diffs between my PR branch and the official package provided from the curl website.

#!/bin/bash

CURL_UPDATE_VERSION=7.75.0
CURL_PATH_NAME=curl-$CURL_UPDATE_VERSION

GIT_REPO_BRANCH=vendor/curl-7.75.0
GIT_REPO_URL=https://github.com/patrikjuvonen/mtasa-blue.git
GIT_REPO_CURL_PATH=vendor/curl/

echo 1. Download and extract $CURL_PATH_NAME...
curl https://curl.se/download/$CURL_PATH_NAME.tar.xz | tar -xJ

echo 2. Fetch and checkout the vendor update branch $GIT_REPO_BRANCH from $GIT_REPO_URL...
git fetch $GIT_REPO_URL $GIT_REPO_BRANCH:$GIT_REPO_BRANCH
git checkout $GIT_REPO_BRANCH

echo 3. Start checking integrity...
diff -r --strip-trailing-cr $GIT_REPO_CURL_PATH $CURL_PATH_NAME

echo 4. Completed.
exec $SHELL
