Hm.  How would you recommend going about writing a script that takes
output from a command, transforms it, and then feeds it back into
that command's input?  Are sockets a more reliable way to do this kind
of IPC on Cygwin?

See reinit_git and try_dump from t9010-svn-fe.sh for context.


On the one hand, sockets work fine on cygwin so that path would probably work.

However, I don't understand why git would need to consume its own output - If named pipes are really needed to use git-svn because git-svn depends upon git feeding the same git process, then that package should not be available on cygwin or any other platform that does not support fifos. If not, then I don't think the test suite should require fifos or any other construct with the same git process feeding itself either, it just blurs the line about what is actually being tested.
