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

    Sample output from HTML file...
