Michal SojkaI imported my repositories from CVSNT server 1.11.1.3 and on some of them import died with error like this:
Fetching libvideo\libvideo/libvideo.dsp v 1.1.1.1 Unknown: error
After some searching I have found that the reason is probably wrong naming of my directories (i.e. directories with the same name at different locations). I'm not CVS guru but guess that CVS server tracks what we are downloading and assumes that we are downloading all subdirectories (at all levels) to one common directory. If more subdirectories have the same name, it refuses to send the latter ones to avoid overwriting the first one.
The dump of TCP communication was like this:
C: Argument -N C: Argument -P C: Argument -r C: Argument 1.1 C: Argument -- C: Argument video/libvideo\libvideo/libvideo.dsp C: Directory . C: /d//cvs C: co S: E cvs server: existing repository d:/cvs/video/libvideo does not match d:/cvs/video/libvideo\libvideo S: E cvs server: ignoring module video/libvideo\libvideo/libvideo.dsp S: error
This patch solved the problem for me. When the error is received, instead of dying immediately, the connection is closed, then opened again and the second fetch attempt is executed. --- git-cvsimport.perl | 11 +++++++---- 1 files changed, 7 insertions(+), 4 deletions(-)
