Subject: cvsserver: nested directory creation fixups for Eclipse clients
X-Git-Tag: v1.3.0-rc1~63
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=6be32d4791126da12e0eade17362ae8ad3f13971;p=git.git

cvsserver: nested directory creation fixups for Eclipse clients

To create nested directories without (or before) sending file entries
is rather tricky. Most clients just work. Eclipse, however, expects
a very specific sequence of events. With this patch, cvsserver meets
those expectations.

Note: we may want to reuse prepdir() in req_update -- should move it
outside of req_co. Right now prepdir() is tied to how req_co() works.
