* Revert "Fix values to methods in __main__"Dylan Baker2016-12-28
| | | | | | This reverts commit 581ed2987bd456d2894637a30bb5a14a4caa5f9b. Fixes #942
* db/message: fix whitespaceDylan Baker2016-12-27

* fix odd continuation and indentationDylan Baker2016-12-27
| | | | This is just whitespace changes.
* db/utils: fix bad hanging indentDylan Baker2016-12-27

* db/message: replace __cmp__ with rich comparisonsDylan Baker2016-12-27
| | | | | | | | | | | | | | | | | | | | | | This replaces the deprecated __cmp__ function with the more modern __lt__, __eq__, and __ne__, and then uses functools.total_ordering to implemented the remaining pieces of the rich comparison protocol automatically. It also make use of the NotImplemented singleton, which python uses to signal to rich comparators that this class doesn't no how to compare to the other class, which results in the complementary method from the other class being used, and if both return NotImplemented than a TypeError is generated. There are two reasons to make this change. First, python 3 only supports rich comparisons, and second rich comparisons are much faster than using cmp (and the __cmp__ protocol) because cmp is called at least 3 times per element, while a rich comparitor is called one per element. functools.total_ordering is in the standard library from 2.7 and 3.3, and will implement the rich comparison protocol provided that __eq__ and at least one of __lt__, __le__, __ge__, or __gt__ are implemented. It does not (oddly enough) implement __ne__, so I've implemented that manually.

* db/envelope: Don't call dunder method when not necessaryDylan Baker2016-12-27
| | | | | | | There are times to call dunder methods explicitly (double underscore methods, like __contains__), but that's usually only required when dealing with inheritance. In this case using the standard 'k in d' syntax is clearer.
* db/attachment: remove useless deleteDylan Baker2016-12-27
| | | | | This dict key is deleted, and then promptly replaced. The deletion is useless, the replacement does the same thing.
* db/attachment: replace all caps name with PEP8 like nameDylan Baker2016-12-27
| | | | | Using file_ instead of FILE still avoids shadowing the builtin, but also doesn't stand out so much.
* ui: Use xrange instead of rangeDylan Baker2016-12-27
| | | | They are the same, except xrange returns an iterator instead of a list.
* commands/utils: Refactor exception caseDylan Baker2016-12-27
| | | | | | | | | This removes the use of range (originally I simply replaced it with xrange, but the realized that the use of range was itself strange), and replaces it with generators and iterators to create the dictionary. This has the advantage of only creating one concrete instance (the choices dict), and being slightly easier to read and understand, as well as not needing to call len() repeatedly.
* Dirty fix for case-(in)sensitive MIME matching.Pol Van Aubel2016-12-26
| | | | | Simply cast every string to lower() when matching MIME media type and subtype. Matching is always case-insensitive as per RFC2045, 5.1.
* Use abc module to signal abstract base classesDylan Baker2016-12-21
| | | | | | | | | | | | | The Completer class is abastract, and it's complete method is also abstract. Using ABCMeta achieve two thing, first it will cause an error if a developer doesn't overwrite the method in a subclass. And second that it tells the static analysis tools to ignore the unused arguments in the signature, since this is the definition of a signature, not an actual function. By the same logic addressbook.AddressBook, and account.Account have been extended to use ABCMeta as their metaclass and have had their abstract methods decorated with the abstract method attribute.
* Replace unused arguments with _Dylan Baker2016-12-21
| | | | | | | | | | This patch replaces a large number (but not all) unused arguments with the standard ``_`` placeholder. This has the advantage of signaling that these values are unused. There are a number of places that I've chosen not to apply this, largely in methods that have publicly define signatures that they inherit (usually from urwid).
* Don't use dict.keys when not necessaryDylan Baker2016-12-21
| | | | | | | | | | | It's pretty easy to get caught up using dict.keys (or iterkeys) when one doesn't need to. This patch corrects two cases where it's not needed, the first is the case of inclusion. ``x in mydict.keys()`` is equivalent to ``x in mydict``, but without the need to generate a list and walk it. The second case is when calling set() on a dict, ``set(mydict)`` will create a set object of the dict's keys, without the need to create one in memory and is significantly faster than ``set(mydict.keys())`` or even ``set(mydict.iterkeys())``.
* ui: Don't build lists in memory for assertDylan Baker2016-12-21
| | | | | | This patch changes an assertion to avoid building a list in memory by using dict.keys() and then concatenating it (building a second list in memory). This is both faster and uses less memory.
* settings/manager: remove list comprehension for clarityDylan Baker2016-12-21
| | | | | | | The use of a list comprehension here saves one line of code, but doesn't make the code clearer, a simple loop is more obvious. This also replaces ``if not v or v == ''`` with simply ``if not v``, since they're equivalent.
* Use dict's iter methodsDylan Baker2016-12-21
| | | | | | | | This patch replaces a number of uses of dict.items, dict.values, and dict.keys with their iterative siblings. The advantage of using the iterator version is that they don't copy the keys, values, or items, but simply return references. This reduces memory usage and may speed up the these operations a bit.
* widgets/search: make method that doesn't use self a static methodDylan Baker2016-12-21

* db/thread: Set some protected variables in the constructor.Dylan Baker2016-12-21
|
* db/thread: Avoid intermediate data structureDylan Baker2016-12-21
| | | | | | This patch removes the need to create an intermediate dictionary while calculating the authors of a thread, it does so by working directly with the _authors list.
* db/thread: don't create multiple lists to sortDylan Baker2016-12-21
| | | | | | | | | | | | | | | Currently this function takes a list, splits into two lists based on whether or not a function returns None, sorts the list that isn't None, and then appends the list of None to the end. This creates 4 new concrete lists on each method call, requires the use of 3 filter + lambda pairs, and calls list.sort(). Pretty complicated and inefficient. This patch replaces that with a single sorted() function call with a kay function that replaces None with a value that is guaranteed to sort less than what Message.get_date() will return, but will not cause a comparison to None (which is an error in Python 3.x). This is all based on iterators and avoids the need for filter or list concatenation. This should result in only one new list being created.
* Define instance attribute in constructor.Dylan Baker2016-12-21
|
* Replace map() and filter() with comprehensionsDylan Baker2016-12-21
| | | | | | | | This had the advantage of being more readable to people without a functional programming background, and it avoids the need to use lambdas which are both slow and have many corners in python. In a few cases it also allows us to use a generator expression instead of a materialized list, which save some memory.
* Fix "superflous paren" warnings from pylintDylan Baker2016-12-21
| | | | | | | | | In alot/helper.py this is a fairly obvious change. In alot/buffers.py I've taken the liberty of replacing a somewhat odd use of multiplication that relies on the bool class (True and False) implementing an __int__ method. These are used to add the 's' to the end of 'message' if there are more than one message (thus messages), this is much clearer (and more correct) when implemented as a ternary instead.
* Use raw strings with backslashesDylan Baker2016-12-21
| | | | This just adds the `r` prefix to a few strings.
* Fix values to methods in __main__Dylan Baker2016-12-21
| | | | | several of these don't take a self argument. In one case self is needed, in the others decorating them as static methods fixes the behavior.
* tests: Add tests for alot.db.thread.Thread.get_authorDylan Baker2016-12-21

* db/thread: define Thread._authors in constructorDylan Baker2016-12-21
| | | | This is needed by unittest that mock Thread.refresh.
* Drop little used helperDylan Baker2016-12-19
| | | | | | | | The safely_get helper is just a wrapper around try/except, and is used twice in the whole code base, in the same function. It really doesn't even end up saving code because to get around line wrapping a lambda is assigned (which is not the greatest style wise), it ends up saving one line of code when it's called, and the function itself is 16 lines long.

* fix interpolation in config files #902.Patrick Totzke2016-12-16
| | | | | | | | | Configobj's string interpolation feature does not work as expected in account sections of alot configuration files. The reason is that interpolation is done in ConfigObj.__getitem__ which alot does not use directly for account sections. This patch causes all values to be read via ConfigObj.__getitem__ explicitly.

* | use open as a context manager instead of oneline open().read()Dylan Baker2016-12-14
| | | | | | | | | | | | | | | | While open().read() is nice for its terseness it has the problem that it causes an fd to leak until the gc collects it. For short lived scripts this isn't a big deal, but for a program like alot that run for long periods of time it's better to be correct and ensure that the fd is closed.
* | use open() as context managerDylan Baker2016-12-14
| | | | | | | | | | | | | | | | | | | | This uses open() as a context manager instead of calling close() explicitly. This has the advantage of closing even in the event of an exception, being easier to visually inspect for correctness, and being the more modern idiom. This does leave one case of file.close(), where FILE is opened in an if tree.
