* daca2: Improve package sorting using natsort
This switches the external dependency from semver to natsort, and
improves comparison of packages where one or more of the packages do not
use semantic versioning (major.minor.patch).
This also makes daca2-download and daca2-getpackages work with python 3.
In theory, they should work with python 2 as well, but I have not tested
it.
* Make daca2 scripts executable
* Update hashbangs to python3
* Update usage description
To avoid specifying python version in the usage description, just
show how to execute the scripts and leave the rest to the shebangs.
* No need to specify python version in start_donate_cpu_server_test_local.sh
Leave it to the hashbang instead.
* donate-cpu-server.py: Use tools to prepare code to work with Python 3
The following commands were used for these changes:
futurize -1 -w donate-cpu-server.py
2to3 -w donate-cpu-server.py
* Make the server work under Python 3
Manually fixed the Unicode issues. Received data is decoded, sent data
is encoded.
* Add backward compatible type hints (in comments)
This enables better static analysis and suggestions in an IDE.
* Fix Pylint warning "Comparison to literal"
* .travis.yml: Fix/enhance pylint verification and Python compilation
donate-cpu-server.py is only Python 3 compatible, so it must be ignored
for pylint verification under Python 2.
All Python scripts that were verified with pylint under Python 2 are
now also verified with pylint under Python 3.
* donate-cpu-server.py: Add shebang and mark script as executable
* start_donate_cpu_server_test_local.sh: Directly execute server
Since the server script is executable now and has a shebang it can
be directly executed.
* Use Python 3.0 function annotations instead of comment type hints
Reference: https://www.python.org/dev/peps/pep-3107/
The client script will exit after the specified number of packages
have been processed. 0 means infinitely.
Useful for example to regularly quit the script, check for updates to
the client and start it again. Or as an alternative to the `--stop-time`
argument.
Python 3 directly decodes the text when it is read(). If there is any
invalid UTF-8 character in the text an exception is thrown (IIRC it is
UnicodeDecodeError). Opening the file with `error='ignore'` avoids
throwing an exception and just ignores the invalid character. Since
this is only possible since Python version 3 there must be extra code
for older versions.
The test script has been enhanced. It now also uses a package which
contains a file with at least one invalid UTF-8 character.
Indirectly the scripts (at first the server test script) also document what needs to be done to setup a (local) server.
The productive client script can be used by everyone who wants to support daca@home, not only for testing. But i still think it is good to have it under /test to not lose too much clarity / lucidity in the /tools directory.
