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.
This change doesn't make much sense on its own - the real goal is to
prepare some ground for easier implementation of URI-encoding of the root
location.
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.
`false` is a pretty bad default value as most user want to track
the real download.
By removing the default value, we force user to make a choice.
We could have change the default value to true but it would have been
a silent API change and we don't want that.
User may already have a pointer to the `Download` and it is not protected
against concurrent access.
We could update the status of new created `Download` as by definition,
no one have a pointer on it.
But it better to not do it neither :
- For consistency
- Because the first call on update status may be long on windows (because
of file preallocation). It is better to not block the downloader for that.
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`).
