- Preparation work for using six or future module for Py2/3 compat. The
code will be written in Python 3 with Python 2 fallbacks.
- Added some Py3 imports with Py2 fallbacks to make it easier to remove
Py2 code in future.
- Replace xrange with range (sort out import as top of files in future).
- Workaround Py2to3 basestring issue with inline if in instances. This means
every usage of basestring is more considered.
- Replace iteritems and itervalues for items and values. There might be a
performance penalty on Py2 so might need to revisit this change.
There is a bug in Py2 setuptools where the build fails if unicode dict keys
are passed to package_data:
`package_data must be a dictionary mapping package names to lists of wildcard patterns`
The easiest workaround is to remove unicode_literals use in setup.py as it is not that important.
- Python 3 renames `unicode` type to `str` and introduces `bytes` type.
- Python 2.7 has `bytes` but is only an alias for `str` so restricted
to comparisons but helps keep compatibility.
- To test for unicode string on Py2 and Py3 uses the "''.__class__" type.
- Remove usage of utf8encode and just encode, problems with bytes being passed
in code will be picked up faster.
- Where possible refactor out isinstance for try..except duck-typing.
* Added `from __future__ import unicode_literals` to every file so
now all strings in code are forced to be unicode strings unless
marked as byte string `b'str'` or encoded to byte string `'str'.encode('utf-8')`.
This is a large change but we have been working towards the goal of unicode
strings passed in the code so decoding external input and encoding
output as byte strings (where applicable).
Note that in Python 2 the `str` type still refers to byte strings.
* Replaced the use of `str` for `basestring` in isinstance comparison as
this was the original intention but breaks code when encoutering unicode strings.
* Marked byte strings in gtkui as the conversion to utf8 is not always handled, mostly
related to gobject signal names.
* Where possible use 'from gtk import ...', i.e. if repeated often or under 10 individual imports.
* Remove osx_check to not show svg. It's only an issue on Windows so should work fine...
* Rearrange and deduplicate code into d.u.g.common for getting pixbuf from files.
* Use 'from gtk.gdk import...' to make it cleaner to apply GTK3 changes in future.
* Move generic icon code from torrent_data_funcs to common.
* Fix pylint import warnings and add WindowsError to pylintrc file.
* A rather disruptive change but for a few reasons such as easier to read,
easier type, keep consistent and javascript code uses single quotes.
* There are a few exceptions for the automated process:
* Any double quotes in comments
* Triple double quotes for docstrings
* Strings containing single quotes are left e.g. "they're"
* To deal with merge conflicts from feature branches it is best to follow
these steps for each commit:
* Create a patch: `git format-patch -1 <sha1>`
* Edit the patch and replace double quotes with single except those in
comments or strings containing an unescaped apostrophe.
* Check the patch `git apply --check <patchfile>` and fix any remaining
issues if it outputs an error.
* Apply the patch `git am < <patchfile>`
* Use print function
* Fix except as statements
* Remove old twisted 8 code
* Remove empty docstring
* Refactor try statement to only contain the relevant import and
disable pylint import msgs.
* Use flake8 noqa and pylint comment and drop pyflakes workarounds.
* Replace the uses of long with int.
* Replace im_func with __func__ as it has been provided for Python 3 forward-compatibility.
* Fix next/__next__ for Python 3 compatibility.
* Remove the long number literal
* Ensure freespace() returns int
To make the code more Python 3 compatible, I've made a few changes to how we handle keys() or iterkeys() calls on dictionaries. All functionality should remain the same.
* Remove the use of .keys() or .iterkeys() when iterating through a dictionary.
* Remove the use of .keys() when checking if key exists in dictionary.
* Replace dict.keys() with list(dict) to obtain a list of dictionary keys. In Python 3 dict.keys() returns a dict_keys object, not a list.
* Ensure all file descriptors are closed. Using the with statement ensures
closure.
* The main problem was with thousands of unclosed file desciptors from
tracker_icons mkstemp.
* Use a prefix 'deluge_ticon.' to identify created tracker_icon tmp files.
Due to the nature of passing a command and args to cmd.exe and then
to a batch file in Windows any ampersands in execute args need to be
double-escaped so prefixing with tripe-caret (^^^&) is the fix for this.
* The main fix here is adding os.environ to the command call otherwise in some configurations
the extraction would fail. Was unable to reproduce locally but users confirm this fix works.
* Refactored the code to properly report errors if the extract command fails along with actual
command output.
* Bump version to 0.5.
There is some discrepency between pep8 and pylint for line
continuation (https://github.com/PyCQA/pylint/issues/747) but
with some minor layout changes both can pass and code looks fine,
if not better in places.
This should fix problems with errors occuring when failing to
enable plugins. Errors in plugin handling are handled better
and properly logged.
WebUI plugin in particular had issues when being enabled and disabled
multiple times because it was trying to create DelugeWeb component
each time it was enabled. If deluge-web is already listening on
the same port, enabling the WebUI plugin will fail, and the checkbox
will not be checked.
There are still some issues when enabling/disabling plugins by
clicking fast multiple times on the checkbox.
