Hi Rob,
As a quick way of introduction, my name is Rob Oakes. I'm writing for two
reasons:
First, I wanted to say thank you for developing a wonderful piece of software.
I've just started using ownCloud to manage my business calendar, contacts, and
files and I absolutely love it. It meets every need that I have in a well
designed and elegant manner, and it is open source. I can't wait to see where
it will be headed in the near future.
The second reason I am writing is with a development question. Because I see a great deal
of promise in ownCloud, I am very eager to begin adding support for its various features
to some of the software products my company develops. As a test case, I wanted to add it
to a backup client called "Time Drive" that I develop/maintain
(https://launchpad.net/time-drive). In the process of writing an ownCloud specific
backend, though, I've come across a problem I can't figure out the solution to:
Whenever I upload files to the web server through a "PUT" command, I find that I am
unable to change the "Last-Modified" ('getlastmodified' in WebDav) property. Putting
'Last-Modified' into the header with the proper value is ignored. As is every other header I can
think of ('lastmodified', 'getlastmodified', 'setlastmodified', 'Modified-Last', etc.)
I've also tried to change the last-modified time using a PROPPATCH request,
also to no avail.
Hmm, it's a PROPPATCH request on the file resource, with property name
'lastmodified' and the time as UTC epoch value. That should work. The
line you pointed out does it for the csync ownCloud module.
By looking at the source code for sync
(http://git.csync.org/users/freitag/csync.git/tree/modules/csync_owncloud.c?h=dav,
line 1423) and through the archives of the mailing list
(http://www.mail-archive.com/[email protected]/msg01793.html), it seems that
ownCloud supports the modification of the 'Last-Modified' property. (This is
how the ownCloud csync backend works, right?)
That's right. Csync works on times and modifies it that way.
have fun,
Klaas
