No close tag in scheduler reply

[zombie67]

I have two machines that are trying to report tasks, and are getting this:

22924 yoyo@home 12/4/2013 6:16:38 AM update requested by user

Thanks!

The only thing I see in the logs is, that the host tries to report a lot of results which were already reported. Things like this:

Code: Alles auswählen

2013-12-05 03:42:29.4669 [PID=13374] [CRITICAL]   [HOST#104170] [RESULT#23241956 ogr_131203182003_42_0] result already over [outcome=3 validate_state=2]: result already reported as error

e=0)

Usually the close tag isn't missing when such an error message occurs. BOINC just doesn't find it.

The core client doesn't contain a full XML parser, it can handle only one tag per line. So if any of the tags "hides" behind a different tag, the whole XML structure will be messed up and BOINC is unable to recognize it.

Maybe you could check the sched_reply for such duplicate XML tags, it might help to narrow down the problem, things like .

Code: Alles auswählen

</project_files></scheduler_reply>

I guess it helps to just search for

Code: Alles auswählen

><

which should not occur in a "line-by-line XML".

[zombie67]

I am not sure if that suggestion was directed to yoyo or me. But I could not find any "><" in the sched_reply_www.rechenkraft.net_yoyo.xml.

Here it is, if that helps:

My browser doesn't complain, that this XML is wrong.

My browser doesn't complain, that this XML is wrong.

A web Browser (unlike the core client) has a full XML parser builtin.

I guess this is the problem (taken from an older CC version) :

Code: Alles auswählen

int SCHEDULER_REPLY::parse(FILE* in, PROJECT* project) {
    char buf[256], msg_buf[1024], pri_buf[256];
...
    while (fgets(buf, 256, in)) {
...
        } else if (parse_str(buf, "<message", msg_buf, sizeof(msg_buf))) {

but the XML has a lot of message text :

Code: Alles auswählen

more than 6500 characters in a single line, not containing any linefeed - much longer than the size of the buffers involved in the parse method. My guess would be that the core client chokes on this one.

@zombie67 : If you don't want to hand-edit client_state.xml and remove those results, do a project reset. I guess that's the only other chance to get rid of that message. The results have been reported anyway so not too much should get lost.

Thanks for the info! I'll reset the project.
