SID-01698: programmatic upload

I'm trying to programmatically upload a file to a topic using http post multipart/form-data. I get no errors from TWiki but files are not uploaded (even if the attach table is filled in if I ask for that feature). Looking at the filesystem I see no directory nor file is created. I think file and directory permissions are ok, 755 on apache:apache. Am I missing something? I enetered all the fields required by the upload cgi script. Is there a way to get extra debug info?

Discussion and Answer

Not sure, but things to check:

• Turn off {CryptToken}{Enable} in configure to see if this causes the issue. I do not recommend to turn this off in a public TWiki. Depends on security needs if it is an internal TWiki
• What kind of {LoginManager} do you use? If template login causes issues try apache login (using different twiki/bin & apache config, but same data, pub, lib, etc)
• Do debug, add print STDERR "something\n"; debug statements into lib/TWiki/UI/Upload.pm and watch the output the the apache error log.

Hi again, first of all, I'm trying to access programmatically the TWiki from a Java app. Maybe I didn't point out this very clearly in the initial support request. The calls to TWiki are done all through HTTP-POST. Said that:

• I don't think the problem is on the crypttoken because I make other-than-upload calls in an identical fashion and I'm able to send the crypttoken input correctly. Moreover, I tried to remove that input and I do get an error from the TWiki. So I think that is not my problem;
• regarding the login, I'm using java.net.Authenticator and, same as above, I get no refused connections with, e.g., save or edit POSTs. Also the upload call returns no error on connection, nor I see apache log issues on that;
• I didn't tried yet the last suggested solution, I'll report as soon as I'll test it.
