You only need an "up to the minute" version if that's how you locally maintain your changes -- by communicating them through the master SUP server. This assumes commit privs. If you don't have commit privs, once a day or once a week (depending on your level of activity) is enough to handle it for you. You can cut the intermediate sup server traffic by 33% if you institute multiple reader/single writer locks and use a pseudo writer lock for the SUP area mirroring. If commiters follow the "it must run before you release the writer lock" protocol, then you will be guaranteed a buildable image on every SUP. > > Since your assumptions are invalid for one of the two most common > > distribution method, the rest of the proposal is not completely valid. > > Since those who have the direct access are not really inhibited by this > proposal, I suggest that you reconsider it in view of the other 99.99% of the > folks for whom my assumptions apply. I don't totally agree with all aspects of the proposal, since I have multple trees for multiple concurrent projects, and it won't help me out that much because of it. But this is a point in its favor. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
