Handling URL redirection with JGit

JGit is a Java library to programmatically do actions versus a local or remote Git repository. It is quite powerful, but it comes with an issue: when trying to connect to a remote repository it doesn't handle URL redirection. When you try to connect to a remote repo like in the example below (the connection attempt is to one of my repos in GutHub):

String uri = "https://github.com/virtualramblas/publishtokafka-plugin.git";
String userName ="XXXXXXX"
String password = "YYYYYYY"
LsRemoteCommand remoteCommand = Git.lsRemoteRepository();
try {
            Collection <Ref> refs =
                    remoteCommand.setCredentialsProvider(new UsernamePasswordCredentialsProvider(userName, password))
                    .setHeads(true)
                    .setRemote(uri)
                    .call();
} catch(GitAPIException e) {
            e.printStackTrace();
}


everything is fine because there is no redirection. But trying to connect to another remote repository URL which performs redirection the following exception happens:

Caused by: org.eclipse.jgit.errors.TransportException: https://<url>/<repo_name>.git: 302 Found

Unfortunately the JGit library can't handle this, but a workaround is possible. Using curl with the following options:

curl -u <username>:<password> -v https://<url>/<repo_name>.git

From the output of this command you can retrieve the URL to which this one redirects and then replace the original one in your application code. This way the connection is successful and you can do all the actions you need to the remote repo.

Turning Python Scripts into Working Web Apps Quickly with Streamlit

 I just realized that I am using Streamlit since almost one year now, posted about in Twitter or LinkedIn several times, but never wrote a blog post about it before. Communication in Data Science and Machine Learning is the key. Being able to showcase work in progress and share results with the business makes the difference. Verbal and non-verbal communication skills are important. Having some tool that could support you in this kind of conversation with a mixed audience that couldn't have a technical background or would like to hear in terms of results and business value would be of great help. I found that Streamlit fits well this scenario. Streamlit is an Open Source (Apache License 2.0) Python framework that turns data or ML scripts into shareable web apps in minutes (no kidding). Python only: no front‑end experience required. To start with Streamlit, just install it through pip (it is available in Anaconda too): pip install streamlit and you are ready to execute the working de...

jOOQ: code generation in Eclipse

jOOQ allows code generation from a database schema through ANT tasks, Maven and shell command tools. But if you're working with Eclipse it's easier to create a new Run Configuration to perform this operation. First of all you have to write the usual XML configuration file for the code generation starting from the database: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <configuration xmlns="http://www.jooq.org/xsd/jooq-codegen-2.0.4.xsd">   <jdbc>     <driver>oracle.jdbc.driver.OracleDriver</driver>     <url>jdbc:oracle:thin:@dbhost:1700:DBSID</url>     <user>DB_FTRS</user>     <password>password</password>   </jdbc>   <generator>     <name>org.jooq.util.DefaultGenerator</name>     <database>       <name>org.jooq.util.oracle.OracleDatabase</name>     ...

Load testing MongoDB using JMeter

Apache JMeter ( http://jmeter.apache.org/ ) added support for MongoDB since its 2.10 release. In this post I am referring to the latest JMeter release (2.13). A preliminary JMeter setup is needed before starting your first test plan for MongoDB. It uses Groovy as scripting reference language, so Groovy needs to be set up for our favorite load testing tool. Follow these steps to complete the set up: Download Groovy from the official website ( http://www.groovy-lang.org/download.html ). In this post I am referring to the Groovy release 2.4.4, but using later versions is fine. Copy the groovy-all-2.4.4.jar to the $JMETER_HOME/lib folder. Restart JMeter if it was running while adding the Groovy JAR file. Now you can start creating a test plan for MongoDB load testing. From the UI select the MongoDB template ( File -> Templates... ). The new test plan has a MongoDB Source Config element. Here you have to setup the connection details for the database to be tested: The Threa...
