If there is no response from the server, `load_data` would panic
with: `response status`.
This patch removes the `expect` in favor of an error message that we
couldn't get a response from the server for a given url.
Cache-busting was previously done with a compile-time timestamp. Change
to the SHA-256 hash of the file to avoid refreshing unchanged files.
The implementation could be used to add a new global fn (say,
get_file_hash) for subresource integrity use, but that's for another
commit.
Fixes#519.

Also change a few other things to use it, as noted in CHANGELOG.md.
TODO:
- Write a couple of tests: updated field, last_updated template variable
One slight open questions: should `updated` default to the value of
`date` rather than to None? Then pages with `date` could safely assume
`updated`.
The variable name matched the RSS tag it ended up in, but was misleading
about what it actually was—because if you actually want “last build
date”, you should use `now()`. (Due to the potential for edits, I think
that either there should be an official `updated` field on pages, or
that these templates should use `now()`.)
This includes several breaking changes, but they’re easy to adjust for.
Atom 1.0 is superior to RSS 2.0 in a number of ways, both technical and
legal, though information from the last decade is hard to find.
http://www.intertwingly.net/wiki/pie/Rss20AndAtom10Compared
has some info which is probably still mostly correct.
How do RSS and Atom compare in terms of implementation support? The
impression I get is that proper Atom support in normal content websites
has been universal for over twelve years, but that support in podcasts
was not quite so good, but getting there, over twelve years ago. I have
no more recent facts or figures; no one talks about this stuff these
days. I remember investigating this stuff back in 2011–2013 and coming
to the same conclusion. At that time, I went with Atom on websites and
RSS in podcasts. Now I’d just go full Atom and hang any podcast tools
that don’t support Atom, because Atom’s semantics truly are much better.
In light of all this, I make the bold recommendation to default to Atom.
Nonetheless, for compatibility for existing users, and for those that
have Opinions, I’ve retained the RSS template, so that you can escape
the breaking change easily.
I personally prefer to give feeds a basename that doesn’t mention “Atom”
or “RSS”, e.g. “feed.xml”. I’ll be doing that myself, as I’ll be using
my own template with more Atom features anyway, like author information,
taxonomies and making the title field HTML.
Some notes about the Atom feed template:
- I went with atom.xml rather than something like feed.atom (the .atom
file format being registered for this purpose by RFC4287) due to lack
of confidence that it’ll be served with the right MIME type. .xml is a
safer default.
- It might be nice to get Zola’s version number into the <generator>
tag. Not for any particularly good reason, y’know. Just picture it:
<generator uri="https://www.getzola.org/" version="0.10.0">
Zola
</generator>
- I’d like to get taxonomies into the feed, but this requires exposing a
little more info than is currently exposed. I think it’d require
`TaxonomyConfig` to preferably have a new member `permalink` added
(which should be equivalent to something like `config.base_url ~ "/" ~
taxonomy.slug ~ "/"`), and for the feed to get all the taxonomies
passed into it (`taxonomies: HashMap<String, TaxonomyTerm>`).
Then, the template could be like this, inside the entry:
{% for taxonomy, terms in page.taxonomies %}
{% for term in terms %}
<category scheme="{{ taxonomies[taxonomy].permalink }}"
term="{{ term.slug }}" label="{{ term.name }}" />
{% endfor %}
{% endfor %}
Other remarks:
- I have added a date field `extra.updated` to my posts and include that
in the feed; I’ve observed others with a similar field. I believe this
should be included as an official field. I’m inclined to add author to
at least config.toml, too, for feeds.
- We need to have a link from the docs to the source of the built-in
templates, to help people that wish to alter it.
Two main purposes of changes here:
- To make the formatting and indentation of the raw output prettier;
- To simplify the HTML yielded by dropping unnecessary bits.
The 404 changes are a tad more extensive, altering the actual wording to
match conventional stub 404 pages a little more.
* get_url takes an optionnal parameter

Remove a link tag mistakenly imported from Atom XML namespace. The tag
was used to specify the link to the feed itself which is not supported
by RSS 2.0:
https://cyber.harvard.edu/rss/rss.htmlFixes#967
Many servers will return errors (e.g. 400/403) to requests that do not
set a User-Agent header. This results in issues in both the link_checker
and load_data components. With the link_checker these are false positive
dead links. In load_data, remote data fails to be fetched. To mitigate
this issue, this sets a default User-Agent of
$CARGO_PKG_NAME/$CARGO_PKG_VERSION
Note that the root cause of this regression from zola v0.9.0 is that
reqwest 0.10 changed their default behavior and no longer sets a
User-Agent by default:

* Treat 304 (Not Modified) requests as valid.
* Add tests for 301-to-200 links, 301-to-404 links, and 500 links.
This helps to test redirections and the previously-added
response.status() checking for non-success status codes in check_url().
* Make names for HTTP mock paths unique, to avoid weird behavior. It
seems like mocks with the same path can potentially bleed between
tests, so you may end up with an unexpected response which causes the
test to sometimes pass and sometimes fail.
* Fix Clippy warnings about String::from(format!()).
Certain tests involving HTTP requests were sometimes hanging
indefinitely, so this uses Mockito for HTTP mocking. This seemingly
resolves the issue and makes these tests more reliable.
The existing can_fail_404_links test has been renamed to
can_fail_unresolved_links, to represent what actually occurs in the
test. The can_fail_404_links test now deals with a proper 404
response.
Just to be clear, the check_site test in the site component will
still create outgoing HTTP requests (due to the URLs used in the
test_site), so this commit only uses HTTP mocking where possible.

Add method get_translation(lang, key) into Config struct that retrieves
translated term from parsed configuration or error when either
desired language or key is missing.
Use the new method in Trans struct implementing global Tera function
trans().
Add unit test to cover both happy and error path for translation
retrieval in both config and templates crate.
Clippy is returning some warnings. Let's fix or explicitly ignore
them. In particular:
- In `components/imageproc/src/lib.rs`, we implement `Hash` explicitly
but derive `PartialEq`. We need to maintain the property that two
keys being equal implies the hashes of those two keys are equal.
Our `Hash` implementations preserve this, so we'll explicitly ignore
the warnings.
- In `components/site/src/lib.rs`, we were calling `.into()` on some
values that are already of the correct type.
- In `components/site/src/lib.rs`, we were using `.map(|x| *x)` in
iterator chains to remove a level of indirection; we can instead say
`.copied()` (introduced in Rust v1.36) or `.cloned()`. Using
`.copied` here is better from a type-checking point of view, but
we'll use `.cloned` for now as Rust v1.36 was only recently
released.
- In `components/templates/src/filters.rs` and
`components/utils/src/site.rs`, we were taking `HashMap`s as
function arguments but not generically accepting alternate `Hasher`
implementations.
- In `src/cmd/check.rs`, we use `env::current_dir()` as a default
value, but our use of `unwrap_or` meant that we would always
retrieve the current directory even when not needed.
- In `components/errors/src/lib.rs`, we can use `if let` rather than
`match`.
- In `components/library/src/content/page.rs`, we can collapse a
nested conditional into `else if let ...`.
- In `components/library/src/sorting.rs`, a function takes `&&Page`
arguments. Clippy warns about this for efficiency reasons, but
we're doing it here to match a particular sorting API, so we'll
explicitly ignore the warning.
* Change the behavior of the template rendering:
* Check if the template bare name is present
* Check if the template is part of a theme
* Fallback to defaults
* Change the behavior of the shortcode rendering:
* Call the template rendering function
* Prepend `__zola_builtins/` to most of the default elements in `ZOLA_TERA`
* Add a test to verify the presence and content of a `404.html` page
from a theme's template
Since we are using a builtin template, we can be assured to have the
target file in place. Middleware renamed since it is bound directly to
the concept of handling 404s.
