| 3 | ## Script to build and test the latest python from svn. It basically
|
|---|
| 4 | ## does this:
|
|---|
| 5 | ## svn up ; ./configure ; make ; make test ; make install ; cd Doc ; make
|
|---|
| 6 | ##
|
|---|
| 7 | ## Logs are kept and rsync'ed to the host. If there are test failure(s),
|
|---|
| 8 | ## information about the failure(s) is mailed.
|
|---|
| 9 | ##
|
|---|
| 10 | ## This script is run on the PSF's machine as user neal via crontab.
|
|---|
| 11 | ##
|
|---|
| 12 | ## Yes, this script would probably be easier in python, but then
|
|---|
| 13 | ## there's a bootstrap problem. What if Python doesn't build?
|
|---|
| 14 | ##
|
|---|
| 15 | ## This script should be fairly clean Bourne shell, ie not too many
|
|---|
| 16 | ## bash-isms. We should try to keep it portable to other Unixes.
|
|---|
| 17 | ## Even though it will probably only run on Linux. I'm sure there are
|
|---|
| 18 | ## several GNU-isms currently (date +%s and readlink).
|
|---|
| 19 | ##
|
|---|
| 20 | ## Perhaps this script should be broken up into 2 (or more) components.
|
|---|
| 21 | ## Building doc is orthogonal to the rest of the python build/test.
