QUESTION
I used ftputil to download a batch of files from a FTP server. It raised the error ftputil.error.FTPIOError: [Errno 60] Operation timed out.
As described in Documentation – ftputil,
keep_alive()attempts to keep the connection to the remote server active in order to prevent timeouts from happening. This method is primarily intended to keep the underlying FTP connection of an FTPHost object alive while a file is uploaded or downloaded. This will require either an extra thread while the upload or download is in progress or callingkeep_alivefrom acallbackfunction.
I called keep_alive from a callback function with,

Answered 2021-May-01 at 14:32This isn't directly an answer to your question, but it may help finding an answer for your particular problem yourself. Also, a ticket on the ftputil website is better for help with debugging a problem. That said, I think it's fine to ask on StackOverflow first since you don't know in advance if the problem is a simple one or not. :-)
Since FTP is a stateful protocol, client and server can't send arbitrary commands at a given time. The allowed commands and possibly replies are determined by the state the connection is in. See also the state diagrams in RFC 959.
To work around this limitation, ftputil creates a new FTP connection behind the scenes for each remote file object [1]. With this approach, you can still send commands like chdir or start a download while another is still in progress. However, this means that from the perspective of the server, all these FTP connections that come from a single FTPHost object are independent connections, so each of these connections can have their timeout at different times, depending on the usage pattern of the respective connection.
For example, there was ftputil ticket 141, where presumably the main connection initiated by the FTPHost object timed out while a connection used for downloading was still usable.
In your case, it might be helpful to find out which of the underlying connections is timing out (the initial connection or a connection for a remote file). You can use ftputil.session.session_factory to create factories that have FTP debugging enabled (see the documentation).
Unfortunately, a timeout of 60 seconds is quite short, so there are relatively many chances for timeouts.
Especially given the possibility of timeouts in FTP connections, my advice is to write software for FTP transfers in a way so that you can restart the operation (ideally with a new FTPHost object for robustness) where it was interrupted by the timeout. So far I haven't been able to come up with a way to universally work around timeouts. In simple cases you may actually be better off using ftplib directly, although ftputil has robustness and latency improvements that ftplib doesn't have. Using ftplib doesn't save you from timeouts, but at least you don't have any "hidden" connections that may make debugging more difficult.
[1] That said, if you close a remote file in ftputil, the underlying FTP connection can be reused unless it's not timed out. The library checks for a timeout before it reuses the connection.
The picture regarding timeouts is even more complicated by ftputil caching a lot of information from the server to reduce latency. For example, if you call FTPHost.getcwd(), the current directory is retrieved from a cached attribute, not by sending a PWD command to the server and thereby resetting the timeout. Stat information from directory listings is also usually cached.

QUESTION
I am trying to implement a Google Cloud Function with Python 3.8 Beta as runtime while using the pyodbc module. I am getting an error while trying to implement it.
As far as I understand by reading other Stack Overflow questions, to use pyodbc on a linux distribution you need to sudo install some things before you can use pyodbc as it needs some OS specific resources.
Does anyone has an idea how to do this or knows another way to make pyodbc work in a Google Cloud Function?
The implementation error google cloud functions is throwing:
...ANSWER
Answered 2020-Aug-24 at 18:07It's not possible. The pyodbc project requires the unixobdc-dev platform package, which is not in the list of system packages included in the Cloud Functions runtime.
Instead, you may want to use Cloud Run which allows you to define your own runtime and install any platform packages that you want.
QUESTION
I'm trying to make a launcher for my Java desktop application (separated applications), wich has to look for an updated version of the main application on the server. My idea is to store the app version inside of a text file on each side.
I found (thanks to Google san) the way to read the version from the text file and download the jar directory with all of it's content (both on server side). I'm using the Apache Commons Net FTP library btw.
The problem comes when I try to download the jar directory from the server after beeing reading the text file. I get the text file content correctly, the files download fails though.
If I switch code lines to download the stuff first and then read the text file, both of them works well, but we all know that's not the way an update check should be.
I've been looking and I don't get what I'm doing wrong. It's my first time working with this library.
This is the code I'm working with:
...ANSWER
Answered 2020-May-12 at 00:56I found the problem. Apparently I just have to flush the server replies with ftpClient.completePendingCommand() after reading the version from the text file. I still do not get why happens just with one of both processes though, I would like to understand.
Thanks!:)
QUESTION
I am connected with ssh on a remote server from my local machine.
I run my Snakemake on the remote server.
I would like to use as input of a rule, a file that is on my local machine.
Of course, since I run my Snakemake on the server, the server become the local machine and the local machine the remote one (for Snakemake).
ANSWER
Answered 2020-Mar-04 at 08:36So I did a quick & dirty search in the source code of Snakemake, and Snakemake makes use of ftputil which requires a username and password. When you do not provide a ssh-key path to Snakemake this password will default to None, which then gets passed to ftputil.
See Snakemake source.
I agree that the default behaviour should default to something more sensible like ~/.ssh/id_rsa, but unfortunately it doesn't.
QUESTION
I'm running a Python3 script on the terminal, and on my terminal it writes out a lot of print() statements that I added, as well as output from libraries I'm using.
I wish to save the output in a file, so I run the script like this.
python3 myscript.py > logfile.txt
Everything I print() from within Python now goes into the file as I want, instead of being printed to my terminal.
However, within this script I'm also using the ftputil library to download files, and some output from ftputil still shows on the terminal where I ran the script. So now the output of my program is split in 2 parts, which makes it less useful.
...ANSWER
Answered 2019-Aug-22 at 20:47You're right, this deprecation warning is from ftputil.
ftputil uses the Python warnings module to show this warning. The warnings module not only outputs warnings (by default to stderr), but also offers ways to control which warnings are actually shown (see The Warnings Filter and Temporarily Suppressing Warnings).
You can suppress the ftputil warning with
QUESTION
To get the modification time of a file I use path.getmtime from ftputil, but since the DST-change the returnvalue of recently created files has an offset of one year, saying the last modification time of new files is from last year. Actually the file was modified one hour in the "future".
The reason for this is the OS, where the file is stored, is running on DST, but where the script is running its non-DST.
Overall I want do delete files older than a threshold, but right now it's also deleting the newest file, because it says it's from 2018.
I tried converting the timestamp with datetime.utcfromtimestamp into UTC time but obviously getmtime does not return the actual timestamp of the file. It already sets it to 2018, last year, cause it may look like the value is from the future.
Lets say its 2019-04-04 10:00:00 UTC. A file on a host running on DST (UTC+1) is created at 10:45
...ANSWER
Answered 2019-Jun-18 at 21:04If you have write access in a directory on the FTP server, you can call FTPHost.synchronize_times(). This will temporarily create a file on the server, ftputil will parse the file's timestamp, delete the file and then adjust the time offset between server and client for this FTPHost instance.
If you don't have write access on the server, you can still set the offset "manually" with FTPHost.set_time_shift(time_shift), where time_shift is defined as "server_time - client_time in seconds".
See https://ftputil.sschwarzer.net/documentation , section "Time zone correction".
