[Snip masses of changes]

Great job! 

Sometimes I have no choice but to write pages where some CSS/JS defeats
NetSurf and while I try to make them degrade gracefully, this isn't
always true where I have lifted code from others but this page has now
sprung into legibility thanks to your hard work.

http://www.youngtheatre.co.uk/archive/yt/timelines/

Text and objects are no longer rendered outside the DIVs. Hurrah!

Codethink sponsored work on NetSurf

2017-05-02 Thread Michael Drake 


Over the past few weeks I've been able to spend time
contributing to open-source projects at work.

Codethink [1] values open-source software, and so I
was approved to work on NetSurf and related components
while I was between projects.  I'd like to thank
Codethink for this opportunity, which I very much
value and appreciate.

What follows is a summary of the development I've been
able to accomplish during this time.

[1] http://www.codethink.co.uk/


LibCSS (CSS parsing and selection library)
==

* Added parsing and selection support for the CSS3
  box-sizing property.


NetSurf
===

Core: HTML layout engine


* Added support for the CSS3 box-sizing property.  This
  helps us assign element widths and heights as the web
  page author intended.
* Extended :after pseudo element handling to cover the
  table display type.  This improves layout of pages that
  use a variant of the clearfix CSS trick for clearing
  floats.
* Fixed the handling of the CSS min-width and max-width
  properties to correctly affect the auto-width left and
  right margins.
* Added support for width attribute on HR element.
* Fixed use of uninitialised value in CSS presentational
  hint handling, that had potential to reduce the
  likelihood of computed style sharing.
* Improved layout tree dump, to make debugging layout
  problems easier.

Core: Content handling
--

* Improved logging, making it easier to track HTML contents
  through a session, for debug purposes.
* Removed bogus assertion in the HTML object fetch handler,
  which would sometimes crash the browser.
* Fixed bug in content state machine, which made aborted
  fetches cause their contents to get stuck in the cache.
  This would happen on JavaScript location assignments.

Core: URL handling
--

* Improved file: URL handling.
* Removed redundant code.
* Improved hexadecimal handling.
* Improved test suite.

Core: Hotlist (bookmarks/favourites)


* Added support for saving the hotlist automatically after
  entries are added or removed.  This helps prevent loss
  of hotlist changes if NetSurf is unable to save the file
  on exit.
* Added support for read-only hotlist mode, which can be
  selected by frontend code.  In this mode, the hotlist
  file may be read, and the hotlist updated, but changes
  are never saved to disc.

GTK frontend


* Fixed bug where different pango layout contexts were used
  for measuring and painting text, which in some situations
  caused either lines with overlapping text, or large spaces
  between bits of text on a line.
* Slight optimisation to the text line break handling code.
* Rewrote bitmap rendering plotter.  The new implementation
  is many times faster for tiled rendering, such as for
  repeating background images, and simplifies the handling
  of scaled plots.

RISC OS frontend


* Improved handling of external hotlist managers, by setting
  the core hotlist to read-only mode, when configured to use
  an external manager.


NetSurf's JavaScript engine (Duktape)
=

NetSurf uses the excellent Duktape JavaScript engine.
URL: http://www.duktape.org/

* Updated NetSurf and nsgenbind (our JavaScript binding
  generator) from Duktape 1.6 to Duktape 2.0.  We had
  been stuck on the 1.X series due to API changes
  in Duktape 2, and lack of time to make the transition.
  Duktape 2.0 provides greater performance, amongst many
  other improvements.
* Added support for HTML style comments (ES6 spec) to
  Duktape and upstreamed it to the Duktape author, Sami
  Vaarala.  This feature had been requested by our users.
* Updated NetSurf from Duktape 2.0 to the recently
  released Duktape 2.1, which gives further performance
  gains, adds the HTML stlye comment handling, and other
  improvements.
* On the advice of the Duktape author, enabled Duktape's
  fastint build option, for faster integer arithmetic.


LibNSGIF (GIF decoding library)
===

* Complete rewrite of LZW decompression.  The new
  implementation is both 30% faster and cleaner code.
  It also now handles LZW codes that span three sub-blocks.
  (Although these are unlikely to actually appear in the
  real world.)


LibSVGTiny (SVG decoding library)
=

* Build system improvements to fix warnings about use of
  gperf-generated code.



Cheers,

Michael

We made a change to the fetch behavior some time ago that resulted
in us not waiting very long for a server to respond.

We've moved back to the old behavior in build CI #3406.

As someone who has been a little lax in keeping up with the bleeding edge
I'm really happy having downloaded #3403 to find it seems quicker than
the 'ancient' version I was using.

The spurious carriage returns which showed up inside tables seem to have
gone. Hurrah.

Review: Codethink sponsored work on NetSurf, LibCSS and LibDOM
==

Over the last couple of weeks I have been lucky enough to be able
to do work on the NetSurf project at work.
At [Codethink](http://www.codethink.co.uk/) we have an arrangement
that allows engineers to fill time between projects by making
contributions to certain open source projects.

My request to work on [NetSurf](http://www.netsurf-browser.org/),
and more particularly, its [LibDOM](http://ns-b.org/projects/libdom/)
and [LibCSS](http://ns-b.org/projects/libcss/) sub-projects was
approved and I was able to get a good amount done.


LibDOM
--

Most of my time has been spent improving LibDOM; the Document Object
Model library.  Since the recent moves towards adding JavaScript
support in NetSurf, various parts of LibDOM that had never been used
are beginning to get exercised.  This has revealed various issues.

The first series of changes affected the specialisations of HTMLElement:

* Added a new, more efficient means of identifying an HTML element's
  tag name.
* Fixed some missing HTML element specialisations.
* Made some optimisations relating to how the appropriate specialisation
  for an element is determined.
* Made the internal workings of HTMLElement specialisation more consistent.
* Exposed a function to enabled client applications to use the new
  efficient means of identifying HTML element tag types.

nodes with registered listeners.  In most cases, when there is no
scripting involved we can now avoid generating the list at all.

but when I immediately tried again it displayed immediately.

Curious why that should be.
