This commit drops the usage of the userlang cookie in the backend but
not in the frontend. UI language control should be broken at this point
and will be fixed in the next few commits.
After upgrading my OS to Ubuntu 22.04 the language selector button
didn't show up in the viewer taskbar. Investigation shows that the id
used in the CSS was applied to the wrong HTML element (the enclosing
<a> rather than <img>).
Created a generic function multipleQuery which takes:
1. string (representing a comma separated list)
2. param (the value to query on using Xapian).
Category and language query will use this function.
Before this fix suggestion links were built out of fully URI-encoded
book name and article path components despite the fact that this measure
was taken against only a few dangerous symbols such as '#', '?', '"' and
'\'. However, URI-encoding the slash symbols in the path has some
undesirable side-effects (see #958).
Henceforth only the problematic symbols are encoded in the article path
component. The book name is still fully URI-encoded since I don't see
any counter-arguments.
meson and ninja both depends on python3 which received an update.
This python3 update fails to install when linking.
This temp fix removes those files. Hopefully a future update will remove the need
for this hack
Now (in a library.xml flow) a book is considered to contain an
illustration only if both "faviconMimeType" and "favicon" attributes
are set to non-empty values.
Presence of the "faviconMimeType" attribute in a book entry in library.xml
file is enough for libkiwix to assume that the book contains an illustration
(even if the "favicon" attribute is missing).
This is a quickfix for the problem observed with external link blocking
during certain history navigation actions (when the cached iframe content is
loaded/restored before the viewer setup is completed).
Since external link blocking doesn't depend on the translations (that
are asynchronously loaded during the viewer setup) it can be performed
unconditionally. However, the current dependence of `on_content_load()`
on viewer setup has to be addressed too.
Before this fix clicking an external link in the viewer iframe had no
effect (other than an error being reported in the browser dev tools
console) because the attempt to navigate the top browser context was
suppressed due to sandboxing - the click handling code changed the
target of the link but navigating to that target was blocked. Now the
click handler works as follows:
1. Changes the target of the link to the catch page only if the
link is going to be opened in a new tab or window (in this case
sandboxing restrictions do not apply).
2. Otherwise directly navigates the viewer window to external URL
or the catch page.
An unhandled scenario is opening an external link in a new tab/window
via a middle click or context menu - such events cannot be intercepted
and therefore there is no way of blocking external links accessed in
the said way.
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.
