copy_files method does not copy files after download

[DoTheTron]

Hey, I've got a potentially silly question. I'm trying to copy the downloads that I've given to aria to different places. The solution I came up with was to loop over all my downloads I've given to aria, and pass them to aria2p in a list containing a single download each iteration. That way I can specify a different copy location for each download. However, when I call the copy_files() method, even though the output from the method returns true, nothing is actually copied to the location specified. Any idea why that might be?

[Update with Reproduction Code]
I have this stripped down code that you can use to reproduce the problem that I'm seeing. You'll have to get your own magnet link to download though, unless you want the exact one that I'm using. To give a little description of what I'm doing, I made a torrent class containing some information on the torrent I'm using, like the name, magnet link and corresponding aria2 download object. In the reproduction example, I am only initiating one download, and then trying to get aria to move that single download, after completion.

I also started an instance of the aria server with the follow command in terminal:
aria2c --enable-rpc --rpc-listen-port=7200 --rpc-secret=token:password -d /your_directory/ --seed-time=30

#!/usr/bin/env python3

import aria2p
from time import sleep

magnet_link = "your magnet link"
chosen_dir  = "/your_directory/"
copy_dir    = "/your_other_directory/"
WAIT_TIME   = 30

class torrent:
    def __init__(self,torrent_name,src_link,raw_dest,fin_dest):
        self.torrent_name       = torrent_name  # pretty name for torrent, just for human reading
        self.src_link           = src_link      # magnet link stored
        self.torrent_raw_dest   = raw_dest      # The initial chosen directory aria2 will download to
        self.torrent_fin_dest   = fin_dest      # The second direcotry I want aria to copy to
        self.aria2_dwnld        = None          # Will contain aria2 download object later

aria2 = aria2p.API(
    aria2p.Client(
        host="http://localhost",
        port=7200,
        secret="token:password"
    )
)

task_list           = list()
finished_task_list  = list()
task                = torrent("pretty name for torrent",magnet_link,chosen_dir,copy_dir)
task_list.append(task)

task_list[0].aria2_dwnld = aria2.add_magnet(task_list[0].src_link,options=None,position=None)
while task_list:
    # wait for download to complete
    for index in range(len(task_list)):
        task_list[index].aria2_dwnld = aria2.get_download(task_list[index].aria2_dwnld.gid)
        if task_list[index].aria2_dwnld.is_complete == True:
            finished_task_list.append(task_list.pop(index)) # remove finished download from task list & into another list
        else:
            sleep(WAIT_TIME)

# Copy all finished downloads to their appropriate directory
for index in range(len(finished_task_list)):
    out = aria2.copy_files([finished_task_list[index].aria2_dwnld],copy_dir,force=False)
    print(out)

I've also got a snip of my original code attached below:

    for index in range(THREAD_REQUEST):
        set_status(df,task_list[index].prog_stat,task_list[index].torrent_name)
        task_list[index].aria2_dwnld = aria2.add_magnet(task_list[index].src_link,options=None,position=None)
        log_voyage(task_list[index].torrent_name,f"{task_list[index].torrent_name} running")
    while task_list:
        for index in range(len(task_list)):
            task_list[index].aria2_dwnld = aria2.get_download(task_list[index].aria2_dwnld.gid)
            log_voyage(task_list[index].torrent_name,f"{task_list[index].torrent_name} downloading")
            if task_list[index].aria2_dwnld.is_complete == True:
                set_status(df,task_list[index].finl_stat,task_list[index].torrent_name)
                log_voyage(task_list[index].torrent_name,f"{task_list[index].torrent_name} complete")
                finished_task_list.append(task_list.pop(index))
            else:
                sleep(WAIT_TIME)
    for index in range(len(finished_task_list)):
        out = aria2.copy_files([finished_task_list[index].aria2_dwnld],f"{finished_task_list[index].torrent_fin_dest}/{finished_task_list[index].torrent_name}/",force=False)
        print(out)
    system(BCH.DISCONNECTVPN)

Is your aria2c server running remotely? It's a current limitation of the client-server architecture: aria2c does not provide a way to copy/move files, so these functions will only work if the server (aria2c) is running on the same machine as the client (aria2p).

[DoTheTron]

No, the aria2c server is running on the host machine which is also running the code as the client.

OK, thanks.

Well, sorry but with just the snippet above, it's hard to tell what's going on. Could you create a minimum example that reproduces the issue, that I could use to investigate?

[DoTheTron]

Yeah, sorry about that. I've updated the discussion with a stripped down version of my code into a really small script that should recreate the situation. Let me know if it helps, or if there's some more that I can clarify

[pawamoy]

That's great, thanks a lot! I'll investigate asap 🙂

Working on it, closing this discussion since we have an issue (#129).
