Default is to display the encoded version as this provides some security making phishing domains more obvious, and a lot of our frontends are unable to display the full range of UTF-8 characters on the status bar.
Displaying the decoded address in the URL bar requires frontends to be updated (GTK and Amiga done already), and the same caveats apply.
When the fetch of asynchronous javascript scripts completed the
completion of html rendering was not processed leaving the state
machine waiting forever.
Fixed point representation couldn't store 0.65 exactly, so avoid doing
the divide by 100 first.
I will look at moving this into libcss's fixed point header and doing
it in a way that avoids arithmetic overflow, but for now this fixes
el reg layout.
This changes the LOG macro to be varadic removing the need for all
callsites to have double bracketing and allows for future improvement
on how we use the logging macros.
The callsites were changed with coccinelle and the changes checked by
hand. Compile tested for several frontends but not all.
A formatting annotation has also been added which allows the compiler
to check the parameters and types passed to the logging.
This makes the box_move_xy function return a value on all code
paths. This was not really necessary as there is an assert in the path
that could have returned without a value. The gcc optimiser seems
unable to reason about this in this case causing a warning.
The ftell call in the html renderer handling of drag and drop was not
checking its return value for errors which could have resulted in
attempting to read -1 bytes.

The html content script handling needs to invalidate its JavaScript
context when the browsing context (browser_window) containing it is
either closed or the content fetch is aborted (stopped)
Previously the invalidation was only done on browser_window close
which resulted in use after free crashes because of the now invalid
JavaScript context.
When the browser window is about to be destroyed html_close gets
called indicating the browser_window previously associated with the
html content is about to become invalid.
This makes the javascript context invalid within the html content (it
is held by the browser window) when that context is about to be
destroyed. Previously the javascript children would continue to
attempt to use the context after it had been destroyed causing all
sorts of strange errors and failures.
By hiding all but the form selection menu option structure from code
outside of render this reduces the API to the absolute minimum to
support this feature.
Update the form API so instead of directly warning the user it returns
an error code to the caller allowing the appropriate action to be
taken outside the core. Additionally clean up documentation of this
API.
Previously content handler debugging features were accessed by global
variables. This allows the setting of debugging parameters via a
content API giving per content control over debugging features.
Currently only used by the html content handler to toggle global
redraw debugging.
The frontends previously had to use an html renderer API to get the
encoding of a content. This also required the explicit checking of the
contents type rather than using the existing content API to abstract
this knowledge.
This cleans up this header and moves the functionality into more
useful places while reducing the include complexity but only pulling
in whats required.
Update the API which allows frontends to acquire the page features
(images, link urls or form elements) present at the given coordinates
within a browser window.
By making this an explicit browser_window API and using the browser.h
header for the associated data structure with a more appropriate API
naming the usage is much more obvious and contained.
Additionally the link url is now passed around as a nsurl stopping it
being converted from nsurl to text and back again several times.
The netsurf core is driven from numerous operation tables most of
which are now set through a common netsurf_register() interface. The
font and plotting interfaces are currently separate and unlike all the
other operation tables are modified for differing contexts.
This change moves the font operations alongside all the other
operations table and remove unnecessary interaction with the renderers
font internals. Further this also removes the need for css internals
to be visible in frontends.
Values returned by nscss_len2px are actually libcss fixed-points,
so convert the result to pixels. Also reduce the amount by which
the top of descendant bboxes are extended to 3/4 of the text
height, which is the maximum possible amount that the text can
protrude above the box when line-height is reduced.
Prevent leaking of table cell borders that happend when doing
border-collapse: collapse;
Error was do to cell->columns being treated as number of extra
columns spanned minus 1, rather than number of columns spanned.
Track row group that spans belong to, and compare with current
cell's row group to decide whether the previous span affects
current cell's start column.
