Page causes crash
by Richard Torrens (lists)
This may not be a Netsurf thing, but it happens rarely on anything other
than Nersurf.
The whole of this ARMX6's networking crashes. The only way I have found to
recover is a reset.
I have found a page which seems to cause this fairly reliably:
http://www.alamy.com/stock-photo/water-vole-hole.html
Does this happen to anyone else?
RO 5.23 (29-Jun-16)
NS 3.8 (Dev CI #4238) and earlier versions for some time.

Thanks eveyone.
Proves it's not a Netsurf thing, or an ARMX6 thing, but it must be a clash
with something installed on my ARMX6.
I'll keep looking.

Page layout

I suspect the developers don't need more examples of pages that don't
layout properly? But in case they do, try

Experimental treeview search feature
by Michael Drake
Hello,
An experimental search feature has been added to the following:
1. Hotlist viewer (bookmarks)
2. Global history viewer
3. Cookie manager window
To use it, click in the area next to the search icon at the top
of the window, and start typing.
It has currently only been tried under the GTK front end.
It would be helpful if people could put it thoroughly through its
paces. Any feedback gratefully received.
Cheers,

LibCSS: Flexbox property support review
by Michael Drake
Hello,
This is a review of the lcneves/flexbox-tidy branch.
First off I think this is really good work. Almost all the
things I spotted range from minor to trivial.
Aside from the unset values for unit and length in the
min-{width|height} computed style getters, and the fact
that NetSurf is about to do a release[1], I'd be happy
to merge this as-is.
[1] I think NetSurf will need some minor changes to cope
with new values for the display property and the
min-{width|height} properties.
Add codes to flexbox properties
===============================
http://source.netsurf-browser.org/libcss.git/commit/?h=lcneves/flexbox-ti...
+72 - align-content
+ <value> (14bits) :
+ 0 => stretch,
+ 1 => flex-start,
+ 2 => flex-end,
+ 3 => center,
+ 4 => space-between,
+ 5 => space-around,
+ 6 => space-evenly
+ other => Reserved for future expansion.
I'm a bit unsure about the space-evenly value.
CSS Flexible Box Layout Module Level 1 doesn't have this value:
https://www.w3.org/TR/css-flexbox-1/#propdef-align-content
CSS Box Alignment Module Level 3 does have this value and
a few others:
https://www.w3.org/TR/css-align-3/#alignment-values
I think its OK for us to have space-evenly. Same for the
justify-content property.
Parsing: Add support for parsing the flexbox properties
=======================================================
http://source.netsurf-browser.org/libcss.git/commit/?h=lcneves/flexbox-ti...
src/parse/properties/flex.c:
http://source.netsurf-browser.org/libcss.git/diff/src/parse/properties/fl...
+/**
+ * Parse list-style
+ *
s/list-style/flex/
In css__parse_flex():
+ parserutils_vector_iterate(vector, ctx);
+ }
+
+ /* Handle auto, equivalent of flex: 1 1 auto; */
+ else if ((token->type == CSS_TOKEN_IDENT) &&
+ (lwc_string_caseless_isequal(
+ token->idata, c->strings[AUTO],
+ &match) == lwc_error_ok && match)) {
+ error = css__stylesheet_style_appendOPV(grow_style,
+ CSS_PROP_FLEX_GROW, 0, FLEX_GROW_SET);
Our code style is } else { on a single line, and the comment
would be inside the else block before the first line.
Could do something like:
parserutils_vector_iterate(vector, ctx);
} else if ((token->type == CSS_TOKEN_IDENT) &&
(lwc_string_caseless_isequal(
token->idata, c->strings[AUTO],
&match) == lwc_error_ok && match)) {
/* Handle auto, equivalent of flex: 1 1 auto; */
error = css__stylesheet_style_appendOPV(grow_style,
CSS_PROP_FLEX_GROW, 0, FLEX_GROW_SET);
Also I think we could simplfy handling of auto and none
by creating a copule more bools at the start of the function:
bool auto = false;
bool none = false;
Set those true if we get either of those tokens here, and
then below, in the /* defaults */ section, choose the
defaults that get set based on whether:
1. auto is set
2. none is set
3. neither are set

In src/select/computed.c:
http://source.netsurf-browser.org/libcss.git/diff/src/select/computed.c?h...
In css_computed_min_height():
- return get_min_height(style, length, unit);
+ uint8_t min_height = get_min_height(style, length, unit);
+ uint8_t display = get_display(style);
+
+ if (display != CSS_DISPLAY_FLEX && display !=
CSS_DISPLAY_INLINE_FLEX &&
+ min_height == CSS_MIN_HEIGHT_AUTO)
+ {
Spaces used for indent instead of tab on the first and last
inserted likes above. Also out code style doesn't put the
opening brace on a new line.
Same in css_computed_min_width().
For both css_computed_min_height() css_computed_min_width() we
could rearrange to avoid getting display unless the value is
auto. Something like:
uint8_t css_computed_min_height(const css_computed_style *style,
css_fixed *length, css_unit *unit)
{
uint8_t min_height = get_min_height(style, length, unit);
if (min_height == CSS_MIN_HEIGHT_AUTO) {
uint8_t display = get_display(style);
if (display != CSS_DISPLAY_FLEX &&
display != CSS_DISPLAY_INLINE_FLEX) {
min_height = CSS_MIN_HEIGHT_SET;
}
}
return min_height;
}
Finally, I don't think it's OK to override the value
to *_SET and not set appropriate values for length and unit
at the same time. When the computed value is set to *_AUTO
in the cascade it doesn't clear any values for length and
unit. So we should be them up for 0px where we override
min_height.
Same for both css_computed_min_height() and for
css_computed_min_width().
In css_computed_display():
+ } else if (display == CSS_DISPLAY_INLINE_FLEX) {
+ return CSS_DISPLAY_FLEX;
Spaces used for indent on the first inserted line.
In src/select/computed.h:
http://source.netsurf-browser.org/libcss.git/diff/src/select/computed.h?h...
+ * 35 yyybbbaa overflow-y | background-repeat | align-content
+ * 36 bbbbbbaj flex-basis | align-content | justify_content
+ * 37 fffcccjj flex-direction | clear | justify_content
Since align-content and justify-content are split over two
areas, I would say somthing to hint at that in the comments,
e.g.:
* 35 yyybbbaa overflow-y | background-repeat | align-content1
* 36 bbbbbbaj flex-basis | align-content2 | justify_content1
* 37 fffcccjj flex-direction | clear | justify_content2
In the long term perhaps we could consider using a uint32_t
array for the bit data than uint8_t, so its easier to pack
things in without splitting stuff.
+ css_fixed flex_basis;
+
+ css_fixed flex_grow;
+
+ css_fixed flex_shrink;

Spaces used for indent.

http://source.netsurf-browser.org/libcss.git/diff/src/select/propget.h?h=...
-#define BOX_SIZING_INDEX 34

Good spot! Ditto for the similar change in propset.h.
In get_align_content():
+ /* Most significant bit out of three */
+ bits_b <<= 2;
+
+ uint8_t bits = bits_a | bits_b;
Spaces for indent on the first and last lines above.
Similar in get_justify_content().
Selection: Logic for the flexbox properties
===========================================
http://source.netsurf-browser.org/libcss.git/commit/?h=lcneves/flexbox-ti...

http://source.netsurf-browser.org/libcss.git/diff/src/select/properties/o...
+ /* Undo the <<10, because this is an integer */

Use CSS_RADIX_POINT instead of 10. (From include/libcss/fpmath.h)
Or use the FIXTOINT macro from include/libcss/fpmath.h.
