Description
1. Goal
⚫ Copy multiple files in parallel.
◼ Using multi-threads ( one thread for each file transfer )
2. Development environments
- You have to use Python (version 3.6+)
- TA will evaluate your results on Linux. Python can be run over both Window and Linux, but you must NOT use window OS dedicated APIs.
* You can use simple basic libraries (ex: os, time, thread, etc. ), but must implement the main functionalities by yourself. You are NOT allowed to use some libraries that make it easy to implement your assignment. If you want to know whether a particular library is acceptable or not, ask me via the anonymous google sheet.
=> Allowed library example: “os”, “time”, “thread”
=> NOT allowed library example: “shutil”
3. Functionalities to implement
- Assume that there are both text and binary files (text files, image files, and video files) in the same directory where your program runs.
- Get two input strings via a keyboard; one for the source (existing) file name, and one for the destination (non-existent) file name to be copied.
- Read the source file every 10 Kbytes repeatedly, and store it into the destination file.
- Must allow a new copy request while doing previous file copies in parallel.
◼ TA will evaluate up to 10 simultaneous file copies.
- If a file copy is completed, write the file name with the completion time in “log.txt”.
- The time is assumed to be zero seconds when the program starts.
- Present the time information up to two decimal places (e.g. 05 )
⚫ Enter ‘exit’ to terminate this program ( instead of a file name )
4. Sample Results
Figure 1. Console scree
3.43 Start copying GoodMovie.avi to GreateMovie.avi
10.21 Start copying BadMovie.avi to NotBadMovie.avi
32.54 NotBadMovie.avi is copied completely
47.02 GreateMovie.avi is copied completely
