Merge lp:~jeremywootten/pantheon-files/fix-1086929-remake into lp:~elementary-apps/pantheon-files/trunk

[Jeremy Wootten]

Implement auto-sizing of columns in column view.

This is a remake of my previous branch to implement column auto-sizing in column view (currently owned by elementary Developer Community), which included a lot of extraneous formatting changes. In this branch, any changes to existing code have been minimised and it is based on a later revision of trunk. The functional code is the same as the previous branch.

[David Gomes (davidgomes)]

Newline after diff line 58, 82.

167-169, align those correctly.

Good branch, I can confirm the core code is the same, so we can merge this. Plus, it's much much less code, which is good.

[David Gomes (davidgomes)]

Newline after diff line 37 too.

[Jeremy Wootten (jeremywootten)]

OK. So the rule is new line after one-line if statements unless followed
by a brace?

What is the preferred way of aligning 167-169? Align under "g_strconcat"
or the opening paren or elsewhere?

Re aligning; looking again I guess you mean under the first quote (")?

[David Gomes (davidgomes)]

Regarding aligning, yes I mean under the first quote.

The rule concerning new lines is after any if, for/while/foreach/function block, except if followed by another "}" (for example in the end of a class when you close the class and the namespace and the last function in the class). Be it one-line or multiple-ĺines.

[Jeremy Wootten (jeremywootten)]

OK, fixed accordingly.

I think I found a bug with this. When Trash has some amount of files in it (more than 1, or a certain size, but not sure how much), emptying causes pantheon-files to lock up.

I have experienced this twice, still trying to figure out how to reproduce.

[Jeremy Wootten (jeremywootten)]

Just emptied my trash of 1000+ files successfully but it was fairly slow.
 It could be that the longest filename (which detemines the column width)
is being updated after every deletion. I'll look into it.

Merge changes from trunk rev 1351

1347. By Jeremy Wootten on 2013-10-09

Only autosize after all changes to directory done

[Jeremy Wootten (jeremywootten)]

Hello Cody, There does seem to be an issue with deleting or copying large
numbers of files (especially image) files - it can be slow and there is no
progress information so the application appears frozen. I have pushed
another revision to this branch that only autosizes the column after all
deletions are done rather than after each deletion. Please review this
revision, thanks.

There are some other efficiencies that can be made but they are not
connected to autosizing so I have not put them in this branch.

[Cody Garver (codygarver)]

I gathered a big bunch of Trash to do delete tests with and found the problems I previously had with this branch are resolved.

I want to get lp:~jeremywootten/pantheon-files/fix-1178869 merged, do a point release, then merge this branch so it gets some time in trunk for extended testing.
