| | | | | pylint does not like changing the type of a variable. In this case tupples to ints. So add an intermediate variable.

* Makes "future imports" and Python version comments consistent.Fred Wright2016-04-101-2/+3
| | | | | | | | | | | | | | | | | | | | This makes the "future import" statements consistently specify absolute_import, print_function, and division, for maximum consistency between Python 2 and Python 3. Although absolute_import is probably a don't care for top-level programs, if unit tests were ever implemented for the programs they would be imported as modules, making the module import behavior relevant. Note that previous Python 3 fixes are a prerequisite for this change. Also makes the "polyglot comment" consistent across sources. TESTED: Using a version of SConstruct patched to use the target Python for build helpers, ran "scons build-all check valgrind-audit www/hardware.html" with all six supported Python versions. Also ran gegps, gpscat, gpsprof, xgps, and xgpsspeed with both Python 2 and Python 3.
* Fixes leapseconds.py for Python 3.Fred Wright2016-04-101-27/+61
| | | | | | | | | | | | | | | | | | | | | | This fixes two Python 3 issues with leapsecond.py: 1) The urllib module is subdivided in Python 3. Only the 'request' submodule is needed here. Either that or the Python 2 urllib is now imported as 'urlrequest'. 2) The data returned by urlopen() is 'bytes' in Python 3, requiring the polystr transformation to be usable as a string. Also, the (duplicate) isotime() definition here has been updated to match the version in gps/misc.py. It is still duplicated to avoid a dependency on the latter, as is the needed portion of the polystr code. TESTED: Ran "scons build-all check". Also ran "leapsecond.py -f" with all six supported Python versions, and verified that the result matches the existing leapseconds.cache. Did *not* test the updated retrieve() function, but it's not used anywhere.
* Fixes integer division for Python 3.Fred Wright2016-04-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This changes a few integer division cases to use the '//' floored-division operator, matching the normal Python 2 (C-like) '/' behavior, for compatibility with the switch to the "mathematical" divison operator in Python 3 (and in Python 2 with the "future division" import). This was more about keeping the behavior the same than determining whether floored division is actually the proper choice. One place where floored division is definitely wanted is in the GPS week calculations in leapsecond.py, which are now OK for Python 3, though currently that module is only used by SConstruct, and hence not with Python 3. Two other minor fixes: 1) The GPS base date is corrected in the comment in leapsecond.py. 2) The fit_to_grid() function in xgps now consistently returns floats, rather than returning either ints or floats depending on the line width. TESTED: Ran "scons build-all check" with all 6 supported Python versions. Also ran xgps and xgpsspeed with all but 2.6.

* Forward-port gps/ Python client code to run polyglot under Python 2 or 3.Eric S. Raymond2016-03-221-1/+2
| | | | | | | Verified by testing gpsprof under both versions. leapecond.py is also OK. Not yet polyglot: gegps, gpscap.py, gpscat, gpsfake, jsongen.py, maskaudit.py, test_maidenhead.py, valgrind_audit.py, xgps, xgpsspeed.
* Forward-port Python utilities to run polyglot under either Python 2 or 3.Eric S. Raymond2016-03-221-34/+35
| | | | | | For the moment most shebang lines still say 'python2' rather than just 'python'. This is because the client code in gps/ hasn't been touched yet; the internal imports break under Python 3 and that needs to be fixed.
* Change Python hashbang lines to invoke 'python2'Eric S. Raymond2015-07-191-1/+1
| | | | | | We've learned that Ubuntu 15.10 will have python3 as default. The ugly transition gas befun; our only recourse is to hape that all our deployment targets have 'pyton2' do the right thing. Works on 14.10.
