One more question: DDA makes most sense when I want to PUT (write) files from a read-only medium like a CD. But with the current TestDDA implementation I would not any longer be able to PUT files from a CD using DDA (because the client cannot write the file to the requested directory), true? I have to transfer all big files using DIRECT to the node...
In this case the current TestDDA should never become mandatory. ---------- Forwarded message ---------- From: bbackde at googlemail.com <bbac...@googlemail.com> Date: Apr 14, 2007 10:32 AM Subject: TestDDA questions To: Discussion of development issues <devl at freenetproject.org> I read the wiki doc about TestDDA and I have some comments/questions. 1) Please define "READ" and "WRITE" exactly. > Do you plan to do any read operation? After some time I came to the conclusion that "READ" means I want to GET/request a file from freenet, and the node have to write it into the directory. IMHO READ/WRITE with the opposite meaning is to abstract for a client developer *g*. But at least define READ^=GET and WRITE^=PUT to make it clearer. 2) >You can retry to enable DDA requests more than once for either the same or a different directory. Only last test result will be taken into account. Please describe in more detail. Can I TestDDA several directories at the beginning of my application run, because I use multiple directories? Or is always only 1 directory allowed for DDA? And how does the node remember what client tested which directory, is this bound to the socket connection of the client and must be repeated for each new connection? 3) TestDDAReply > You *SHOULD* send a TestDDAResponse message after getting it. *SHOULD* or *MUST* ? I think you must. And I miss some words that the client have to create a new file and write the WriteContent into it. How should a client behave if the file creation fails ? Just skip the creation and let the node recognize that the file is not there? 4) Windows vs. *nix Maybe add some words that the TestDDA concept is bound to the directory name completely. Mapped network drives with different names (e.g. on linux and windows) could be DDA eligable, but due to the directory name used in TestDDA you cannot use DDA there. I will do some tests with the new code. Is it really true that 1028 will make this mandatory? In all other cases you gave us a specific amount of time instead a fix next version number. What if you need to release 2 version in the next few days?
