Comment (by jorbin):

 I've started on a script to accomplish this in the short term with travis
 and github.  How it works:

 1) Fetches the rss of changes to trac.
 2) Finds all the uploaded patches.
 3) Creates a new Branch for each patch
 4) Applies that patch using grunt patch
 5) pushes that branch to github

 Right now it can fail due to patches not being generated from the root or
 otherwise failing to apply. grunt patch will need to have an optional
 argument added to fail if a patch can't be applied instead of prompting
 the user to manually specificy a location (PR welcome if someone can get
 to this before me).  The script looks like this so far:


 {{{
 #!/bin/bash

 # Set DIR based on the current Directory
 DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

 # Get a list the 50 most recent changes
 curl
 "https://core.trac.wordpress.org/timeline?ticket_details=on&max=50&authors=&daysback=90&format=rss"
 |  \
 # find the titles
 grep --line-buffered "<title>\(.\)*</title>" | \
 # Find the attachments
 grep --line-buffered "attached" | \
 # Remove the title tags
 awk '{gsub("<[^>]*>", "")}1' | \
 # Create a attachment url
 awk -F ' ' '{print "https://core.trac.wordpress.org/raw-
 attachment/ticket/" $5 "/" $1 }' | \
 # Find only diff and patch files
 grep --line-buffered "patch\|diff" | \
 # remove the # from the ticket number in the url
 awk '{gsub( "#", "")}1' > .tmp.urls

 while IFS='' read -r line || [[ -n "$line" ]]; do
     BRANCHNAME=$( cut -d '/' -f 6-7 <<< $line )
     echo $BRANCHNAME
     if grep $BRANCHNAME  .patched ; then
         echo "Yo"
     else
         echo "Applying $line"
         cd $DIR
         cd git-clone
         git checkout master
         git pull origin master
         npm install
         git checkout -b $BRANCHNAME
         grunt patch:$line
         git add -A
         git commit -m "add change from $line"
         cd $DIR
         echo $BRANCHNAME >> .patched
     fi
 done < .tmp.urls
 }}}
