f4ddbf3849 Fix tree permissions bug
There was a bug where if you tried to recurse into a directory you didn’t have permission to read the contents of, the error would be ignored.

It now displays the errors.

882ac489ce Much more thorough xattr testing
It now tests a lot more combinations of xattrs on files, as well as xattrs and files and errors as the children of directories.

The recent code changes have touched the part where directories’ xattrs and children are displayed at the same tree level, and there weren’t enough tests for this.

5a2ffd3fbe Generate files with certain timestamps
This is going to be used to test time formatting.

Casualty here is that the “have you not ran the provisioning script in a year?” checker complained about there being files more than a year old, so that now has to ignore the times directory.

f750536420 Add sorting by type
This isn’t perfect, as a file’s type isn’t cached, so it gets recomputed for every comparison in the sort! We can’t go off the file’s `st_mode` flag because it’s not guaranteed to be in any order between systems.

dd8bff083f Override the names of . and ..
There was a problem when displaying . and .. in directory listings: their names would normalise to actual names! So instead of literally seeing `.`, you’d see the current directory’s name, inserted in sort order into the list of results. Obviously this is not what we want.

In unrelated news, putting `.` and `..` into the list of paths read from a directory just takes up more heap space for something that’s basically constant.

We can solve both these problems at once by moving the DotFilter to the files iterator in Dir, rather than at the Dir’s creation. Having the iterator know whether it should display `.` and `..` means it can emit those files first, and because it knows what those files really represent, it can override their file names to actually be those sequences of dots.

This is not a perfect solution: the main casualty is that a File can now be constructed with a name, some metadata, both, or neither. This is currently handled with a bunch of Options, and returns IOResult even without doing any IO operations.

But at least all the tests pass!

84b01f2064 Fix bug where colours were incorrectly applied
exa assumed that the COLUMNS environment variable being present always meant that the output was to a terminal, so it should use colours. But because this variable can be overridden, colours were being incorrectly set!

The ‘fix’ is to stop trying to be clever while only calculating the terminal width once, and instead just stick it in a lazy_static so it’s usable everywhere.

c4447e35b6 xtests for higher order bits
Finally, re-do the permissions extended tests to include the setuid, setgid, and sticky bits, and rename the last two existing ones to match the others (files with the same names as their permissions).

ef5fa90660 Display device IDs when listing devices
Override the size column for block and charater devices, so it shows the major and minor device IDs instead (which are in the Metadata struct somewhere).

This is what ls does when faced with a device.

de60b95850 Don’t core dump when given invalid UTF-8 arguments
By parsing OsStrings rather than Strings, it’s the getopts crate that’s doing the UTF-8 checking rather than us, so if one of them isn’t valid, it’ll just fail to parse rather than crash exa.

Also, save a few allocations here and there.

43bc16dba2 Test change emoji width
The change in 0828133300 means that the width of emoji are used. I think the issue https://github.com/unicode-rs/unicode-width/issues/4 means that the wrong width is being calculated for emoji, and there happens to be one in the example.

108a402dbd Re-prefix the paths found by following symlinks
Fixes #134, a bug that showed symlinks incorrectly as broken, but only when the file was listed directly on the command-line *and* the file was in a different directory to the one exa was being run in.

I’m not sure why the old code used `String::new()`, but it doesn’t seem to affect anything.

9f6376a560 Give broken links a different style in grid view
Because the link style and status are now both available to the function that picks the colour style, we can have it highlight broken links differently.

ba1c8c650f Fix bug where paths took up twice as much space
For some reason, the code that calculated the width of a cell with a path in counted the width of the path twice: once from the ANSIStrings containing it, and once more added on afterwards. This meant that the grid view thought that columns were wider than they really were, meaning fewer could be fit into a grid.

56d4d4c156 Also escape characters in links and headings
Doing this meant that the escaping functionality got used in three places, so it was extracted into a generalised function in its own module.

This is slighly slower for the case where escaped characters are displayed in the same colour as the displayable characters, which happens when listing a directory’s name when recursing. Optimise this, yeah?

eb7e53ef6c Only highlight escaped characters in file names
Rather than the *entire* file name.

The current method is extremely inefficient, but having control characters in file names is also extremely uncommon; it’s something that should be fixed, only eventually.

f8624ed308 Don't prepend current path to symlink targets
It's confusing, and `ls` doesn't do this either. We're not prepending
the current path to all of the directory entries, and the user is going
to interpret the symlink target as relative to the directory containing
the symlink.

956aa85b3b Special-case the root directory when linking to it

f8b82642a6 oops
I think I took this off to see how the output was different. Which means there should really be a better way to check how the output is different, other than running the command and looking!

ef18f9ca91 Protect xtests against different default users
The Vagrant tests assumed that there’d be a user called “vagrant” that would run the tests and create the files by default. Files would be owned by vagrant:vagrant by default, and this worked, until it came time to change that username. The naïve method was a search-and-replace, but this caused problems when the new user’s name wasn’t exactly the same length as the previous one.

So to fix this, we now have our own user, named after the first animal I thought of, that makes the files’ owners and groups independent of the default user of whichever VM image the xtests are running on.

Another place where it was hard-coded was the home directory, which was “/home/vagrant”, where the awkward testcases live. That last one has been changed to just “/testcases”, which has no mention of the user in it.

b885b34aa6 Protect xtests against the passage of time
There was a problem with the Vagrant tests where the year 2016 was hard-coded in as the modified date. This had to be done to make the --long tests use the correct date format, which varies depending on whether the timestamp is in the current year.

Unfortunately, time progresses [citation needed], and what was once 2016 is now 2017, so the date format changed and the tests broke.

Because the Vagrantfile is just a Ruby script, we can look up the current year at runtime and use that instead. There’s also a check added to the test runner that makes sure none of the files are more than 365 days old, because if any are, then it’s time to update the timestamps (or it’s the last day of a leap year)

95596297a9 Basic glob ignoring
See #97 and recently #130 too.

This allows the user to pass in options such as "--ignore '*.pyc'" to not list any files ending in '.pyc' in the output. It uses the Rust glob crate and currently does a simple split on pipe, without any escaping, so it’s not really *complete*, but is at least something.

74358c188a Properly handle errors when following a symlink
Fixes #123. The code assumes that every File that has its link_target() method called would first have been checked to make sure it’s actually a link first. Unfortunately it also assumed that the only thing that can go wrong while following a link is if the file wasn’t a link, meaning it crashes when given a link it doesn’t have permission to follow.

This makes the file_target() method able to return either a file or path for displaying, as before, but also an IO error for when things go wrong.

a7e3456b0d Only engage the view when there are files to show
This changes the way that views are used to display the actual lists of files. It used to pass empty vectors to the view methods, which most of the time would not print anything because there are no files to list — except when there’s a header row which gets printed for no files.

By not calling the view method at all when there’s nothing to print, exa won’t ever print extra things in the view unless it needs to for a file.

This fixes #106 “Don’t print the header if the result set is empty”

54067bf765 Replace the testcases script with a Vagrant VM
See the README section for more details. Basically, with this way, we can store a bunch of existing valid exa outputs, change a VM's environment to match our values, then check that exa still works by comparing outputs.
