When you're using Git, there's really little point in using it,\nsince you don't declare what files you are going to be editing, and\nyou can find out other people's changes at merge time at your leisure\n(not just when *you* want to commit).\n\n> 2) Symlinks to checkout partial repository\n> I believe I read symlinks could be used to checkout part of a\n> repository.

You could use symlinks to *simulate* a bigger\nrepository that is actually made up of smaller repositories.\n\n\nDave.\n"},{"id":"93986","messageId":"82c87da00810260908w2530dbb8j7ebcabe2516d5ed@mail.gmail.com","threadId":"16044","inReplyTo":"ee77f5c20810251641l4892ff12n7b30667c6fcc903c@mail.gmail.com","subject":"Re: From Perforce to Git","fromName":"Brandon","fromEmail":"siamesedream01@gmail.com","sentAt":"2008-10-26T16:08:27Z","receivedAt":"2008-10-26T16:08:27Z","isPatch":false,"sender":{"key":"siamesedream01@gmail.com","avatar":null},"body":"On Sat, Oct 25, 2008 at 6:41 PM, David Symonds wrote:\n> On Sat, Oct 25, 2008 at 2:18 PM, Brandon wrote:\n>\n>> I'm trying to make a comprehensive comparison of Perforce and Git\n>> features.

Since perforce 'forces' developers the checkout files for\nedit, eventually you just ignore these warnings because you don't know\nif someone is really checking something out to make a change they are\ngoing to commit, or just need to make a file writable to experiment\nwith some other feature they're working on etc... This feature would\nwork much better if it were optional. I don't really care about the\nfeature per se I would just like to be able to state that Git can\noffer everything that perforce can.\n I would imagine this would require users pushing their changes to a\nbranch in the central git repo. Then other users could use git log or\ncherry to see what files others are interested in (aka declared they\nare going to edit)? Not that this is necessarily a good way to work.\n\n\n>> 2) Symlinks to checkout partial repository\n>> I believe I read symlinks could be used to checkout part of a\n>> repository.
