I’ve written a GUI for using rsync on windows machines
for third-party use. The project has reached a beta state and is now being
tested in live situations. However, during these tests, I’ve encountered
some odd behavior with specific pathnames. For the record: I’m currently using a cygwin
distribution which includes rsync 2.6.3 to run rsync on Windows machines. The
remote server is running a rsync 2.6.3 deamon through xinetd on a Fedora Core 2
machine. Also for the record: the behavior occurs only when transferring
(downloading) from the server to the client (Linux to Windows) never when
transferring (uploading) from the client to the server. When I start rsync using the following command: rsync.exe --archive --delete --exclude="~$*"
--exclude="*.bak" –vvv
"[EMAIL PROTECTED]::module/1/1100190900/d/Users Shared Folders/DOC

exit(22) While this error should get some attention by my opinion,
this error is however, probably the result from another error: I am trying to transfer from this path: module/1/1100190900/d/ … the error generated, occurs in this path: module/1/1099999800/current/ … Additionally, the server gives a “Connection
Reset”. Prior to this, some correct “permission denied”
errors can be found. Although I don’t know why this error occurs, I might
have an explanation. I stumbled on this problem while trying the following: rsync.exe --archive --exclude="~$*"
--exclude="*.bak" -v "[EMAIL PROTECTED]::module/1/1100190900/d/Users

settings/eric/desktop/b-bv-v-041103-verslag-bestuursvergadering.doc" The client dies with the comment “nothing to do”
but believe me, the file is there. The rsync server log tells a complete
different story: 2004/11/15 2004/11/15 13:25:14 [20736] link_stat
"Bestuur 2004/03-11-04/B-BV-v-041103-verslag-bestuursvergadering.doc"
(in module) failed: No such file or directory 2004/11/15 After this error, I tried to copy a complete directory which
caused the first mentioned problem. It appears that the pathname somehow gets
misinterpreted and split into two separates. Which in this last case, causes
not existing path-/filenames. If this same pathseparation occurs in the first
case, it might explain its behaviour to start working on “module/”
or whatever. In short: It appears that rsync misinterprets certain pathnames,
splits them up to start working on them separately. Doing so, in my case, might have caused an additional error
while receiving files. Either because of the “path separation”
itself or because the working on millions est. of files or it might be a
completely other bug. (transferring “xxxxxxxx/d/Users Shared
Folders/Gebruikers/USERS VdeM total oude server/Archief ex-medewerkers/Jeffrey
Colley/” did not cause any problems but that might be because the
pathnames are shorter because of relativity) Although I’m a developer myself, my experience with
C(++) is VERY limited so haven’t tried to debug rsync myself as I haven’t
got a clue where to start. Any suggestions, fixes or support in anyway will be greatly
appreciated. Regards, Eric van Blokland PS: I mentioned that I had no problems transferring from Windows
to Linux, this I true except for one rare occasion with the system. This is a
minor inconvenience. The directory /cygdrive/d/Users Shared Folders/ gets
transferred (Windows to Linux). This path contains the directory
“Gebruikers VdeM”. This directory will be created on the server,
however, additionally the directory “Gebruikers” gets created
(which doesn’t exist on the client) and the contents of “Gebruikers
VdeM” will be transferred there instead. I mention this (bug?) here as
well, because it might be related. |
