ppc-amigaos gcc 5.3
by Chris Young
Hi
I've just updated the ppc-amigaos toolchain to use gcc 5.3.
It needs building, if somebody can kick that off for me please. :)
Thanks

We're in a mess
by Dave Higton
Guys, we're in a mess. You'll be aware if you read RISC OS Open
fora.
I don't think it should take us many hours of work to tidy it up,
though.
1) We're distributing an out of date version of SharedULib. We
are sending out 1.12; the most recent version is 1.14 (or maybe
1.14-1).
2) The file dates of the resources we ship in !Boot and !System
bear no relation to reality.
3) Although we programmers think of updating !Boot and !System
to be easy, ordinary users don't necessarily feel the same way.
Failing to update is widespread; updating by simply copying
new over old is done by some.
The combination of the above, and non-standard (but entirely
understandable) methods of updating !System, have resulted in
at least one user regressing from SharedULib 1.14 to 1.12, which
in turn stopped one of his important apps working.
Here's what I propose:
a) We update SharedULib to the most recent one. I don't know if
there is anything about the most recent one that will stop NS
working correctly - I can do my share of testing, and other RO
users will chip in too. I haven't seen any reports of problems
yet with 1.14, so it looks promising. Of course, if there is
any known problem, we (and I suppose that means me!) have to
work with the SharedULib devs on an agreed solution.
b) We implement the suggestion from IRC the other evening of
touching the file dates to the last git date. The file dates
are a safety feature, and, by changing file dates frequently,
we throw the safety away.
c) My best suggestion to assist updating of !Boot/!System is
to provide an app along with the NS archive, which users only
have to double-click on (where it is, in the archive) to perform
the updates via the standard Installer tool. I've got an app
to offer, in a very nearly finished version, for you to review.
Comments, please!

It could do with a few more comments. Maybe sprites (anyone think of
a meaningful picture?)

Updating !Boot and !System
by Dave Higton
I'm proposing that the attached Obey file be included in NetSurf
zips for RISC OS. If double-clicked, it should perform the same
update of !Boot and !System as if done manually through the
Configure application.
This follows yesterday evening's dicussion on IRC, which seemed
to peter out about 22:10.

Review: Codethink sponsored work on NetSurf, LibCSS and LibDOM
by Michael Drake
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.

Another area we were spending too much time was in event dispatch.
Previously we would gather a list of nodes from the event target node
all the way back to the root node. Now we generate a list containing
nodes with registered listeners. In most cases, when there is no
scripting involved we can now avoid generating the list at all.

Overall, the there were 99 commits to LibDOM over the course of this stint.
LibCSS
------
Most of the work done on LibCSS was cherry-picking a commit to change
presentational hint handling to be more efficient from another of my
branches, and getting it merged. This was dependent on getting NetSurf
ready to handle the change.
This change to presentational hint handling has made the selection
process much faster for old-school sites that use HTML attributes
for styling content, rather than CSS. It also speeds up the handling
of modern CSS-using sites too, as there is now no overhead when there
are no hints present in the document.

1 file changed, 19 insertions(+)
df3d8e8 Documentation: Fix typos.
1 file changed, 3 insertions(+), 3 deletions(-)
NetSurf
-------
Much of the work done on NetSurf was in response to the changes made
in LibCSS and LibDOM, but I also spent time on bug fixes, cleanups,
and pre-release testing.
The first set of changes were mostly related to JavaScript creation
of HTMLElements, and making use of the new LibDOM API for determining
an element's tag type.

1 file changed, 7 insertions(+), 1 deletion(-)
3cc80b6 Add test for document.write() adding a STYLE element.
1 file changed, 15 insertions(+)
Next was a complete rewrite of CSS presentational hints handling.
Presentational hints are mostly legacy HTML element attributes which
affect the presentation of the elements. They affect the CSS computed
style when no other styles have affected it. Using the new LibCSS API
coupled with the new LibDOM element tag type feature has made support
for presentational hints much faster.
2784514 Rewrite hints handling to be more efficient.
2 files changed, 788 insertions(+), 1123 deletions(-)
eb67607 Merge branch 'tlsa/upfront-hints'
I noticed and investigated an apparent memory leak. Some changes were
made to improve the cache logging, which ruled the cache out as the
cause of the problem. The leak was tracked to a particular issue in
the GTK front end's text rendering.

A few tidy-ups to GTK font rendering and core CSS hint handling:

1 file changed, 1 insertion(+)
3af77ea Can free pango font desc as soon as it's set.
1 file changed, 12 insertions(+), 10 deletions(-)
Finally I fixed several bugs on the bug tracker.
The first was an assertion (crash) that could occur during HTML
layout. The issue stemmed from NetSurf's allowing :before and
:after pseudo elements to be generated for replaced elements.
This behaviour was unspecified in CSS 2.1, but in CSS 3 it is
not permitted.
Second was to remove some code which was complicating the status
bar updating for HTML contents.
Third was to fix the object accounting that is done to keep track
of fetches used for additional resources such as images when
rendering an HTML content. This accounting went wrong when a
fetch for an HTML content was stopped, preventing the content
ever reaching the DONE state, and causing misleading status
bar messages.
3bee7b7 Layout: Don't generate :before and :after boxes for
replaced elements.
2 files changed, 17 insertions(+), 6 deletions(-)
d4a01d5 HTML: Remove some status bar updating code.
4 files changed, 43 deletions(-)
04e61b7 Fix object accounting for aborted HTML contents.
1 file changed, 4 insertions(+), 3 deletions(-)
I also did quite a bit of testing, particularly of the JavaScript
related code, to ensure that there is nothing major blocking the
forthcoming NetSurf 3.4 release.
Overall, there were 20 commits to NetSurf through the course of this stint.
Overview and thanks
-------------------
I was able to get many hours of work done on the NetSurf project over
this period. It has been a very nice experience, working on this
project at work. Thanks to the work environment, I found myself more
focused than I usually am when I'm working on it in my spare time.
Many thanks to [Codethink](http://www.codethink.co.uk/) for providing
this opportunity. I'm very grateful and I've really enjoyed it.
The stats and logs presented were gathered using the following commands

Patch for issue 2170
by Dave Higton
This is a patch for Mantis issue 2170. It's RISC OS specific. It's
a one-liner.
The bug is that, if you hover over a link in a window and then close
the window with Control-F2, the pointer remains as the link pointer
shape. The fix restores the pointer to the default shape before
destroying the window.
The patch was originally submitted by Sprow. The line numbers have
changed slightly, hence the need to re-issue this patch.
I have developer tested it.
It doesn't seem worth creating my own git branch for this (except
as an exercise in git of course).
