[Tilesathome] tah problems with multiple computers

[Sven]

Hi,

there seems to be a severe bug in tilesGen.pl or on the server side.
Today I got access to 10 machines which I used for t at h generation. I
configured them to store their finished .zip-files into a common
directory (UploadToDirectory and UseHostnameInZipname) and use a
loop_uploader. But then after some time I got messages like this:

ERROR: Is your client broken or have you just uploaded like crazy? "You
have more than 150 active requests. Check your client."

A lot of request show up in "Recently finished requests", but quite a
lot (150) of processed requests stayed in "Current active requests", like:
1152,810 12-17 3 1 hour, 5 minutes 10956 1 hour, 4 minutes captionless
1153,810 12-17 3 1 hour, 5 minutes 40879 1 hour, 4 minutes tile,maplint
1154,810 12-17 3 1 hour, 5 minutes 40879 1 hour, 4 minutes tile,captionless
1603,2237 12-17 3 1 hour, 5 minutes 62257 1 hour, 3 minutes
tile,captionless
1290,2482 12-17 3 1 hour, 5 minutes 10956 1 hour, 3 minutes maplint
1168,810 12-17 3 1 hour, 4 minutes 65198 1 hour, 4 minutes captionless
1187,810 12-17 3 1 hour, 3 minutes 10956 1 hour, 3 minutes maplint
1232,810 12-17 3 1 hour 48316 59 minutes maplint

Then I stopped most of the machines and tried to regenerate those
requests manually with "./tilesGen.pl xy 1220 809 12" and so on and
"./tilesGen.pl upload" (which finished in nearly no time). For this
special request I had to do this procedure 3 times!!! before the request
was noticed/processed on the tah server and moved to finished requests.

But it seems that some tiles made it into t at h filesystem (e.g. see
http://tah.openstreetmap.org/Browse/details/tile/12/3628/1613/) even if
they still are marked as "active request".

Btw.
- I noticed that when a lowzoom request could not be completed because
an error in inkscape occoured or something else, it is not given back to
the server.

- It would be a good idea to add a sig-handler to tilesGen.pl, so that
if s.o. pressed CRTL-C the request is given back to the server.

Best regards,
 Sven
