RPC errors with rtcontrol

[fffe]

I'm unable to fetch or filter on the trackers field with rtcontrol, using the current version of pyrosimple against the current master branches of (vanilla) rtorrent/libtorrent.

(test_venv) username@host:~$ rtcontrol --from-view=0123456789012345678901234567890123456789 tracker='*tracker1.net*,*tracker2.net*,*tracker3.net*'

During handling of the above exception, another exception occurred:

Without the filter, this displays the torrent as expected. I'm not sure why this is failing, as those methods appear to exist:

(test_venv) username@host:~$ rtxmlrpc system.listMethods | egrep -i '^t\.(multicall|url|is_enabled)'
t.is_enabled
t.is_enabled.set
t.multicall
t.url

I'm getting a similar error trying to format output as JSON:

(test_venv) username@host:~$ rtcontrol --json --from-view=complete //

The above exception was the direct cause of the following exception:

This time the method doesn't exist:

(test_venv) username@host:~$ rtxmlrpc system.listMethods | egrep -i '^d.session_file'
(test_venv) username@host:~$

Is this a bug or have I skipped a step somewhere?

... the filtering appears to work inconsistently.

rtcontrol is_complete=yes is_open=yes is_ignored=no tracker=\*trackerthatexists.net\* -q displays a list of all torrents from that tracker, as expected.

rtcontrol is_complete=yes is_open=yes is_ignored=no tracker=\*nothingusesme.net\*,\*trackerthatexists.net\* -q shows nothing, which is unexpected.

In my postprocessing scripts (previously working on rt-ps) this used to be treated as an OR; I used it for filtering torrents that matched any of a handful of trackers.

It looks like either it's being treated as an AND here, or it's just silently failing. I'm not sure which.

[fffe]

Okay, I had been missing the rtorrent config, but filtering on trackers is still breaking as described above.

By default --json tries to output all fields, which includes a field that expects the custom command d.session_file. It's a simple method, and definition is available here, but I'll probably rewrite it to not depend on that. In general a full --json is going to be pretty heavy, I'd recommend combining it with -o to limit the fields being fetched.

rtcontrol is_complete=yes is_open=yes is_ignored=no tracker=\*nothingusesme.net\*,\*trackerthatexists.net\* -q shows nothing, which is unexpected.

Here the , is being treated as part of the search string, it doesn't have any special OR significance. Try: rtcontrol is_complete=yes is_open=yes is_ignored=no [ tracker=\*nothingusesme.net\* OR tracker=\*trackerthatexists.net\* ]

Alternatively, you can accomplish the same goal with regexes: rtcontrol is_complete=yes is_open=yes is_ignored=no tracker=/nothingusesme.net\|trackerthatexists.net/

[fffe]

Yeah, I screwed up. I didn't realize there were additional steps beyond just installing the python bits.

Try: rtcontrol is_complete=yes is_open=yes is_ignored=no [ tracker=*nothingusesme.net* OR tracker=*trackerthatexists.net* ]

This throws an error. I tried a couple of different things in case I was missing some escaping, but I always get the same error:

username@host:~/bin$ rtcontrol is_complete=yes is_open=yes is_ignored=no [ tracker=\*nothingusesme.net\* OR tracker=\*trackerthatexists.net\* ] fno=1
username@host:~/bin$ rtcontrol is_complete=yes is_open=yes is_ignored=no [ tracker=\*nothingusesme.net\* OR tracker=\*trackerthatexists.net\* ] fno=1

This worked, thanks.

Is this a functional change from pyrocore? That comma syntax works/worked on my old rt-ps setup.

This throws an error. I tried a couple of different things in case I was missing some escaping, but I always get the same error:

This is happening because of the fno=1 at the end. I'll have to dig into exactly why that is, it's definitely a bug, but moving that to the front of the filters seems to make it work.

Indeed it is, I've never really used the feature so I missed documenting it's removal, that's been add to the migration page now: https://github.com/kannibalox/pyrosimple/commit/7468517c0c7b396a41d8c0a4d74518845b874190
