* 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>`
* 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.
* Replace pause_all and resume_all with pause_session and resume_session
* Pausing all the torrents individually loses the original paused status
so use the libtorrent session pause instead.
* Added a SessionPausedEvent to the method.
* Implemented whitelist support to both core and GTK UI.
* Implemented ip filter cleaning before each update. Restarting the deluge
daemon is no longer needed.
* If "check_after_days" is 0(zero), the timer is not started anymore. It would
keep updating one call after the other. If the value changed, the timer is
now stopped and restarted using the new value.
