quickserve - easy ad-hoc file sharing

Ape · 2010-02-25 18:49:20

Polling for new files in a folder (and automatically sharing also them) would be really useful.

Xyne · 2010-02-25 19:01:08

@agapito
Is it possible to stream using standard HTTP requests?

@Ape
It already does that.

agapito · 2010-02-25 19:37:29

Lol, i don't know. I was asking you... It would be a nice feature if could be implemented.

I wrote the following script to share files from file manager (using quickserve, of course). The problem is if the script is run from file manager, when the script finish, the terminal close, quickserve is also killed. When I run the script in terminal, I can close the terminal after the script finish and quickserve is still running. I'm a rookie at writing bash script, so I'm sure I must have missed something. Please give me some pointers to start quickserve in the background. Here is my code:

#!/bin/bash

function choose {
    PID=`netstat -antuwp|grep -o $PORT.*python|awk '{print $4}'|cut -d'/' -f1`
    TEXT="User: $USER \nPassword: $PASS \nPort: $PORT \nPID: $PID"
    [ $PID ] && ACTION="Stop quickserve" || ACTION="Start quickserve"
    i=`$D --menu "$TEXT" 0 0 0 1 "Edit list" 2 "$ACTION"`
    case $i in
        1) $EDITOR $LIST ;;
        2) [ $PID ] && kill $PID || startqs ;;
        *) exit
    esac
    choose
    }

function startqs {
    [ $PID ] || quickserve -f $LIST -p $PORT --infopage=/info --upload=/home/tri/download -u $USER --password=$PASS &
    sleep 2
    }

if tty -s; then
    LIST=/home/user/.quickservefiles
    D="dialog --stdout --title quickserve"
    PORT=5905
    USER=user
    PASS=password
    PID=`netstat -antuwp|grep -o $PORT.*python|awk '{print $4}'|cut -d'/' -f1`
    if [ $# -gt 0 ]; then
        if [ -f $LIST ]; then
            i=`$D --menu "A list of shared files already existed." 0 0 0 1 "Start new list" 2 "Add to existing list"`
            echo $i
            case $i in
                1) rm $LIST ;;
                2) ;;
                *) exit 1
            esac
        fi
        for FILE; do
            [[ "$FILE" = /* ]] && echo "$FILE" >> $LIST || echo $PWD/"$FILE" >> $LIST
        done
        startqs
    else
        choose
    fi
else
    mrxvt -e $0 "$@" &
fi

Is "file manager" the name of the application or are you referring to a specific file manager?

From a quick glance at the script it looks fine and if it runs as expected from the terminal, the problem probably lies with the application that you're using to launch it, so without knowing exactly which one, I don't have any pointers to give (and might not even if I did know as I tend to run most things from the terminal or via gmrun).

tri1976 · 2010-02-27 16:56:00

The file manager is pcmanfm, but I think it will be the same for any graphical file manager. So how I'm using this is highlight the files I'd like to share in pcmanfm, right click, choose open with the script above. The script runs in terminal and as long as terminal remains open, quickserve is running, but if terminal is close, quickserve stop. Can you add an option to run quickserve as daemon (-d)?

some-guy94 · 2010-02-27 17:33:47

Try running 'disown' after you start quickserv

tri1976 · 2010-02-27 17:46:41

I replace "sleep 2" with "disown", but it still doesn't work. I added "read" after "disown" to keep the terminal open, and quickserve is running while terminal is open, but when I press "enter", terminal close, quickserve stop.

Xyne · 2010-02-27 17:47:51

I'm looking into this right now but so far it seems that the amount of code that I would need to add to enable daemonization is non-trivial. You can get an idea from the following links:

http://www.jejik.com/articles/2007/02/a … in_python/
http://code.activestate.com/recipes/278 … ython-way/

I'm also playing around with the Bash script (e.g. with disown) to try to get it to behave properly as that seems to be the simpler approach in this case.

tri1976 · 2010-02-27 18:00:22

That is a lot of additional codes to daemonize it. I don't understand why it works when the script is run fine from terminal but doesn't work when run from file manager. Somehow quickserve PID is tied to "mrxvt -e $0 "$@ &" PID?

Xyne · 2010-02-27 18:29:37

I'm giving up on this for now because I don't have any more time to play with it. It might be worth posting this as a Bash question in the general programming forum.

I'll look into daemonizing the script again later and may take the opportunity to modularize the code to avoid redundancy with Voracious. The only downside to that approach is that neither would remain a single-file script.

It's solved...the magic command is nohup. So the command for running quickserve in background is something like this

nohup quickserve [options] > /dev/null 2>&1 &; sleep 1

"sleep 1" is needed or quickserve process is still terminated after the shell is closed.

Thanks for posting the solution. I had tried nohup but only without the sleep command (obviously).

sconosciuto · 2010-05-17 19:31:53

I think it's better to add a warning after the Upload button is pressed. A simple javascript can do that:

<body>
  <div id="wrapper">
    <h1>Upload%(backlink)s%(morelink)s%(fewerlink)s</h1>
    <div id="form_wrapper">
      <form action="%(back)s" enctype="multipart/form-data" method="post">
        %(fields)s
        <input class="submit" type="submit" value="Upload" onclick="document.getElementById(\'uploading\').style.display=\'\';"><br><br>
    <div id="uploading" style="display:none;text-align:center">Please wait while your file is uploading</div>
      </form>
    </div>
  </div>
</body>

Xyne · 2010-05-18 01:20:26

Thanks, sconosciuto. I've added it to the latest release.

ntness · 2010-05-18 02:47:37

Just found this little gem and can't wipe the smile from my face...it's so simple. Thanks much for writing this!

FSX · 2010-07-13 20:00:52

I'm using the latest version from the AUR and I found a bug.

It send a wrong mimetype to the browser. Something like ('text/html', None). It's because geuss_type() returns a tuple with the mimetype and the encoding. It was fixed for me when I replaced the following on line 277:

    if not mimetype:
      mimetype = 'application/octet-stream'

With:

    if not mimetype:
      mimetype = 'application/octet-stream'
    else:
      mimetype = mimetype[0]

Xyne · 2010-07-14 04:42:50

Please post the exact error message and the name of the directory or file that you are trying to serve. Based on your location I assume that you are using Arabic and have therefore tried to reproduce this with both directories and files named "عربي" in various levels of nesting, with and without regular names. I was unable to reproduce the error.

I am not sure why it is printing all the file data like cat.

----------------------------------------

If you want to share the file "MonthlyExpences2010.ods", remove "--filelist=". The "--filelist" option specifies a file that contains a list of files to share.

Example:
If you want to share "/tmp/foo" and "/tmp/bar", then you would simply run

quickserve /tmp/foo /tmp/bar

Now if you want to stop serving "/tmp/bar" and start serving "/tmp/baz" instead, you would have to restart the server with the new arguments. This is why there is a "--filelist" option. It lets you change the settings dynamically. Using the files in the previous example, you would first create a list, e.g.:

/tmp/serve.txt

/tmp/foo
/tmp/bar

then start the server:

quickserve --filelist=/tmp/serve.txt

Now to stop serving "/tmp/bar" and start serving "/tmp/baz", you would just edit "/tmp/serve.txt":

/tmp/serve.txt

/tmp/foo
/tmp/baz

Quickserve will detect that the file has been updated and begin serving the files in the new list.

The error was caused by the unexpected NULL bytes in the .ods file, which also jumbled the console output when it tried to print the "paths" in that file.

kgas · 2010-08-05 17:54:29

now clear, thanks.

Xyne · 2010-09-18 11:14:14

I've added SSL (HTTPS) support and moved the base server to it's own module to avoid code reduplication with voracious. I may have introduced new bugs with the numerous changes.

kgas · 2010-09-18 11:28:31

nice. I will try this.

now the normal one gives the following error when i put the username and password. without username/password server starts fine
