In firefox, when PDF content is displayed in the viewer, changing the
viewer URL in the address bar had no effect. The most prominent
manifestation of this bug was the broken book home button but the same
issue was present even if the fragment component of the viewer URL was
edited manually. The bug was a result of
1. an optimization preventing any actions if the new content URL is the
same as the old content URL (this was needed to break the infinite loop
of mutual updates of the top-window and content window/iframe URLs when
any one of them changes).
2. sandboxing of the iframe and inability to access the content URL in
iframe because of cross-origin restrictions when the content is a PDF
displayed by the builtin viewer.
Now that issue is fixed. A slight remaining defect is that the
addressbar URL is still not updated when a PDF file is loaded/displayed
in the viewer.
Added 4 tests for /nojs endpoint
Test 1: no_js_default - Without any filters
Test 2: no_js_eng_lang - With lang=eng as filter
Test 3: no_js_no_books - For 0 results case
Test 4: no_js_download - To test download page
Added cursor type and hints to the UI language selection button. The
hints are always in English since seeing a hint in an unfamiliar language
doesn't help and English is the current lingua franca.
Since kiwixNav is sticky for larger screens now, the tiles area on mobile devices is incredibly low.
This change hides kiwixNav if the screen is scrolled.
The language selector on the welcome page has been replaced with
a smaller button that opens a modal language selector. Though the
code for introducing such a modal language selector has been added
in i18n.js, its appearance relies on styles defined in index.css.
Once this new UI for changing the UI language is approved, it must be
used in the ZIM viewer too.
Known issues:
- selecting the language with arrow keys (using the keyboard only,
without pressing space first, so that the full list of languages is
shown) doesn't work because as soon as the current language is changed
the modal language selector disappears.
If the userlang query param is present in the URL it is used to set the
UI language and then is removed from the URL.
Unlike the ZIM viewer, changing the UI language on the welcome page
isn't recorded in the navigation history (and probably it should work
the same way in the ZIM viewer where the appearance of the web page is
affected by the UI language changes to a significantly smaller extent).
With non-empty root location, the canonic form of the root URL for a
kiwix server is now required to end with a slash (to match the situation
for an empty root location). This requirement enables usage of relative
URLs on the welcome page and resources/scripts loaded through that page.
A slashless root URL is redirected to the slashful version.
This translation has to deal with handling of plural forms which is a
tricky part of internationalization, but we are not going to complicate
things in our code and will offload the headache to translators (they
will have to invent a single message for all numbers).
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.
