Now, the Vagrant VM uses my patched version of git2-rs, which has a modified build.rs file in libgit2-sys, which blocks libhttp_parser from being linked. As you can see by the comment, I’m not a fan of the fix, but at least it works, right?
See #194, and also #255.
Every time I had to build exa, I copied the files manually and checked to make sure they all had the same name. There’s now a script that does all that stuff for me, so I don’t need to remember to do it anymore.
It also does some things that weren’t being done before, including stripping the binary and listing its linked dependencies to we can tell if something like libhttp_parser has slipped in there (see #194)
This commit modifies a specific file timestamp so we test both July (which is 5 characters in French) and December (which is 4 characters in Japanese). It’s also kind of a test for locales as well.
This commit removes the dependency on the ‘getopts’ crate entirely, and re-writes all its uses to use the new options parser instead.
As expected there are casualties galore:
- We now need to collect the options into a vector at the start, so we can use references to them, knowing they’ll be stored *somewhere*.
- Because OsString isn’t Display, its Debug impl gets used instead. (This is hopefully temporary)
- Options that take values (such as ‘sort’ or ‘time-style’) now parse those values with ‘to_string_lossy’. The ‘lossy’ part means “I’m at a loss for what to do here”
- Error messages got a lot worse, but “--tree --all --all” is now a special case of error rather than just another Misfire::Useless.
- Some tests had to be re-written to deal with the fact that the parser works with references.
- ParseError loses its lifetime and owns its contents, to avoid having to attach <'a> to Misfire.
- The parser now takes an iterator instead of a slice.
- OsStrings can’t be ‘match’ patterns, so the code devolves to using long Eq chains instead.
- Make a change to the xtest that assumed an input argument with invalid UTF-8 in was always an error to stderr, when that now in fact works!
- Fix a bug in Vagrant where ‘exa’ and ‘rexa’ didn’t properly escape filenames with spaces in.
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.
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.
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!
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).
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?
This name more accurately reflects which code is being tested (things like .png and Makefile, rather than pipes and sockets), freeing up file-types for *actual* file types to be tested.
The non-contrib Debian one doesn’t come with guest additions, meaning it used rsync instead of Virtualbox shared folders to sync files, meaning edits made in the VM didn’t get propogated back to the host, meaning I got very confused for a while.
Thanks to the parent commit, this shouldn’t be an issue at all: the default user name, which is now “ubuntu” instead of “vagrant” is specified in a lot fewer places, making it much easier to change.
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.
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)
