Reschedule milestones on a new timeline
This isn't a normal Trac Hack, but a small standalone python program that stretches or compresses milestones between new start and stop dates, keeping the time allocations for each the same, proportionally.
It will probably work with 0.10 and 0.9, all it depends on is the milestone table format.
See the Example section for more important information
Usage: reschedule.py [options] Fit Trac milestone due dates into a new time range, preserving relative spacing Options: -h, --help show this help message and exit -D DBTYPE, --dbtype=DBTYPE database type: sqlite (default), postgres, mysql -d DSN, --dsn=DSN connect spec, eg. 'user=foo dbname=bar host=eg.com', or a filename for sqlite systems -s START, --start=START new start date YYYYMMDD -e END, --end=END new end date YYYYMMDD -o OLD, --old=OLD old start date YYYYMMDD -S SCHEMA, --schema=SCHEMA name of schema containing milestone table -c, --commit commit changes to table
NOTE: the --dbtype flag is untested, I developed this for a postgres based system.

python reschedule.py --dsn 'user=someuser host=localhost dbname=trac' \ --old 20071101 --start 20071203 --end 20090630 --dbtype postgres
would reschedule the milestones for a project that originally started 20071101 and ran until the due date of the last milestone to run instead between 20071203 and 20090630, which the same proportional allocation of time for each milestone.
NOTE: without the --commit flag it just prints a table showing what the changes would be, without altering the database. Always test it without the --commit flag first.
Added revision info to macro.
Do not change completed milestones, added verbose flag and option to include rescheduling history in milestone description.
Removing 0.10, didn't mean to create it
