drop python 3.2 and 3.3 compatibility? #65
Description
being compatible with older python versions puts some burden on development:
- tests have to be run on them also (slower test runs, we currently test for 4 python versions)
- some stuff needs special treatment in the code (because it is broken, different or not present)
- we can not use latest releases of some libraries and tools, because they already dropped 3.2 support
python 3.3: https://docs.python.org/3/whatsnew/3.3.html
- new: lzma compression
- new: unicode literals with u"" (this could be interesting if somebody would like to port to 2.7)
- new: getting the terminal dimensions
- new: print(..., flush=True), see sys.stdout.flush() in the code
- new: xattr stdlib code, see look at new xattr stuff in python 3.3 #142
- new: mock is in stdlib, see mock: use mock from stdlib #145
- new: os.replace, .posix_fadvise, .posix_fallocate, .sync, SEEK_HOLE/SEEK_DATA
- new: shutil.disk_usage, stat.filemode, time.process_time
- new: PyMemoryView_FromMemory
- improved: nanosecond precision for stat/utime
- venv comes with it
python 3.4: https://docs.python.org/3/whatsnew/3.4.html
- new: Enum, pathlib, selectors, hashlib.pbkdf2_hmac
- improved: ssl, bytes, bytearray, memoryview, hmac, glob, argparse, os, stat, threading
- pip comes with it
