Temp file transfer

Giulio

Hi,
yesterday i noticed that it happens a lot that i have to transfer non confidential files to friends or servers and I always find it slow to do it.

So, this morning, with ~60 lines of python, based on flask and redis i built a simple service easily usable from command line.

Basically files can be uploaded with a PUT request to the domain index. Since the service is free from ads/tracking bad stuff, and the intended use is temporary the maximum storage of a file is 3 days.

curl --upload-file <localfile> https://files.re/ #Upload with default TTL (24 hours)
curl --upload-file <localfile> https://files.re/160/ # Upload with 160 seconds of TTL
curl --upload-file <localfile> https://files.re/2d3h5s/ # Upload with 2 days, 3 hours and 2 seconds of TTL
curl --upload-file <localfile> https://files.re/2d3h5s/<filename> # Upload with 2 days, 3 hours and 2 seconds of TTL and <filename> as filename

curl https://files.re/ttl/<id> # Get remaining seconds

curl -O https://files.re/<id> # Download with original filename
curl -O https://files.re/<id>/<filename> # Download with <filename>

Please not that the trailing '/' is essential when specifying the TTL: otherwise the TTL will be interpred as the filename.

Source is coming, i'm just tidying it up before publishing.

Redis is used for storing a simple random_string->filename TTL association. However, no cron is needed to clean up the expired files because, for those who didn't know, redis has a 'notifications' feature with will send notifications about keyspace changes to a listener. It is not guaranteed that a notification will be sent instantly when a key expire, but it won't take much since redis checks in the background incrementally or send the notification instantly when something try to access the expired key. Of course other events can be notified too.

I'm sure services like this already existed, but i wanted my own.

Well done!
