Semantic Branch Names

See how a minor change to your branch name style can make you a better programmer.

Format: <type>/#<issueNumber>-<alias>

Example

It's not immediately obvious how to pull down the code for a PR and test it locally. But it's pretty easy. (This assumes you have a remote for the main repo named upstream.)

Getting the PR code

Make note of the PR number. For example, Rod's latest is PR #37: Psiphon-Labs/psiphon-tunnel-core#37
Fetch the PR's pseudo-branch (or bookmark or rev pointer whatever the word is), and give it a local branch name. Here we'll name it pr37:

$ git fetch upstream pull/37/head:pr37

How to generate and apply patches with git?

It sometimes happen you need change code on a machine from which you cannot push to the repo. You’re ready to copy/paste what diff outputs to your local working copy.

You think there must be a better way to proceed and you’re right. It’s a simple 2 steps process:

1. Generate the patch:

git diff &gt; some-changes.patch

Importing/Indexing database (MySQL or SQL Server) in Solr using Data Import Handler

Install Solr

download and install Solr from http://lucene.apache.org/solr/.

you can access Solr admin from your browser: http://localhost:8983/solr/

use the port number used in installation.
