This change adds a <link> element in the head node of welcome page.
Browsers with extensions for RSS will show a sign to navigate to the feed.
The link changes based on current set filters.
Now the root location is URI-encoded too.
In order to properly test this change the root location in the tests was
changed from "/ROOT" to "/ROOT#?" (or "/ROOT%23%3F" in URI-encoded form),
which is why this commit is so big.
Testing of this functionality revealed that the query part containing +
symbols (as replacement for spaces in the parameter values) isn't
forwarded properly as the + symbols are URI-encoded (this is a bug on
the part of the `RequestContext::get_query()` the result of which
already contains URI-encoded +'s).
- Before this change `InternalServer::build_redirect()` only URI-encoded the
article path, ignoring the book name and/or the root location components of
the URL.
- In order to be able to test this fix, corner_cases.zim was renamed to
contain a couple of special URL symbols in its filename. The
`create_corner_cases_zim_file` script was updated accordingly.
The recently introduced ZIM viewer UI language selector looked
adequately nice under Firefox without any explicit styling applied.
Under SeaMonkey, however, its default look and feel was intolerable, so
I used this opportunity to make the UI language selector comply with the
current fashion of the ZIM viewer toolbar.
SeaMonkey doesn't yet support [Window.visualViewport][1]. As a result the
height of the content iframe element was initialized to the default 150
pixels and never changed. Fortunately there is [Window.innerHeight][2]
which is supported from the very first days of the Gecko layout engine.
The difference between `Window.visualViewport.height` and
`Window.innerHeight` is that the latter also includes
- the height of the horizontal scroll bar, if present (but in a correctly
implemented ZIM viewer there shouldn't be a horizontal scroll bar for the
full web-page, so it's OK)
- the height of the on-screen keyboard (which is mostly used on mobile
devices where SeaMonkey doesn't run). And it is also arguable if the
appearing on-screen keyboard should squeeze the iframe or slide over
it (in which latter case it may make more sense to always use `innerHeight`
instead of `visualViewport.height`).

Now that we have proper UI for user language selection, we don't need
the `?userlang=` query parameter present in the URL. If `?userlang=` is
explicitly provided in the URL, it sets the requested language and
disappears.
Known issues
- styling / placement
- language changes via the selector UI are not recorded in the
navigation history
- changing the language via the UI doesn't update the `?userlang=` URL
query parameter
ZIM viewer is now internally internationalized but the UI language
can only be set by providing the `userlang` query parameter in the URL:
Example:
/viewer?userlang=fr#wikipedia_en_climate_change_mini_2021-03/A/index
^^^^^^^^^^^^
Serving the language list as a JS file rather than JSON simplifies
a few things:
- cacheid management;
- having to manually delay the UI initialization until the JSON file
is loaded.
static/skin/languages.js must be generated/updated manually by running
the static/generate_i18n_resources_list.py script.
Before this change, some of the actions related to the initialization of
the viewer were run in the global scope as a side effect of loading
/skin/viewer.js. This change moves those actions into setupViewer().
This change is a quick hack solving known issues with URI-encoding in
libkiwix.
This change removes the slash character from the list of URL separator
symbols in URL encoding/decoding utilities, and makes it a symbol that
is safe to leave unencoded.
Effects:
- `urlEncode()` never encodes the '/' symbol (even when it is requested
to encode the URL separator symbols too).
- `urlDecode(str)`/`urlDecode(..., false)` will now decode %2F to '/';
other encoded URL separator symbols are NOT decoded when the second
argument of `urlDecode()` is set to false (which is the default).
Without specifying the "Path" attribute of the cookie in the "Set-Cookie" header
we end up with multiple instances of the cookie for different URLs. We
want a single "global" cookie for kiwix-serve. Besides we want it to be
"permanent" rather than a session cookie, hence the large (1-year-long)
TTL value for the "Max-Age" attribute.
- Description of a test point was not updated in an earlier commit
that added proper handling of the Accept-Language header. Also
after enhancing the limited implementation it made sense to
add another test point demonstrating that the most suitable language
(rather than just the first one in the list) is selected.
- Now failures of the test case because of a missing Set-Cookie header
are more informative.
The question mark (?) is not a valid filename character on Windows.
Changing to a the pound sign (#) so that this repository can still be
cloned on Windows.
Specifying the = symbol with single-character options makes that
character included in the option value (e.g. -l=en results in the
language of the ZIM file being set to =en).
Directly pointing the suggestion link to a /content/... URL avoids
an unnecessary redirection by the server (and an associated bug
related to redirection of URLs with URI-encoded special symbols in
them that - in the current implementation - go into the target URL
in decoded form).
This change fixes two issues:
1. Presence of URL-specific special symbols (such as ? or #) in the book
and/or article name resulted in a wrong suggestion link. This is
fixed by URI-encoding the book name and the path, too.
2. Presence of a single quote symbol in the book and/or article name
resulted in invalid javascript code in the href attribute of the
suggestion link.
The single quote (') symbol is not URL-encoded (unlike its double quote
counterpart). As a result, enclosing a URL-encoded string in single
quotes may result in invalid javascript. Using double quotes instead is
safe, since both double quote (") and backslash (\) symbols (which are
the only special symbols for such quoting) undergo URL-encoding.
We need a fake language for tests that won't be affected by
modifications made by 3rd party translators (see kiwix/libkiwix#749).
- static/i18n/hy.json was cloned as static/i18n/test.json
- usage of "hy" in unit-tests was replaced with "test"
Before this change RequestContext::get_query() returned a reordered
query string (alphabetically sorted by the parameter names).
This fix facilitiates testing of responses where the request URL appears
in the response.
