Method to diff two Liferay Fix Packs

Issue

• How can I find the difference between two fix pack versions?
• Is there a method to diff fix packs?

Environment

• DXP 7.2   
• DXP 7.1   
• DXP 7.0
• Portal 6.2

Resolution

Quick method: Liferay provides an Online Comparison Tool for DXP Releases

Manual method: In this example guide, we will diff Fix Pack 10 and Fix Pack 12 (DXP-10 and DXP-12)

• Firstly obtain the source code (.src) files for the Fix Packs to be diffed. These can be downloaded from our Helpcenter
  
  
• Important: When going through the diff process, work with the older file first (DXP-10) or the latest file (DXP-12) will be sourced when running the "store" command
• Add DXP-10 source zip to patches folder at this location
  ${liferay.home}/patching-tool/patches
  
  
• Open a terminal window and navigate to the patching-tool folder
  ${liferay.home}/patching-tool
• Run the store command to add DXP-10 to the Patching Tool Store

  ./patching-tool.sh store add liferay-fix-pack-dxp-10-7110-src

  Initializing: store/liferay-fix-pack-dxp-10-7110-src/
  Storing patches: [1%..10%..20%..30%..40%..50%..60%..70%..80%..90%..100%]
  Current patch level is stored as 'liferay-fix-pack-dxp-10-7110-src'.
• Note that a new 'store' folder has been created and populated with DXP-10 data
  
  
• Now add DXP-12 source zip to patches folder ${liferay.home}/patching-tool/patches
• Run the store command again this time with the DXP-12 filename

  ./patching-tool.sh store add liferay-fix-pack-dxp-12-7110-src

• Now we have both Fix Packs in the store ready to diff
  
  
• We'll run a FULL diff on the two stored source files and output to an HTML file
  

  ./patching-tool.sh diff full source liferay-fix-pack-dxp-10-7110-src liferay-fix-pack-dxp-12-7110-src html

  Comparing patch levels...
  Diff file created: /liferay.home/patching-tool/diff/liferay-fix-pack-dxp-10-7110-src-liferay-fix-pack-dxp-12-7110-src-source-diff.html
