GitLab

Detail:
  !Run files for Phoenix requested TextGadgets 0.29, but this can be 0.28
  now, and has been amended. Signal handling in Main.c revised a bit.
Admin:
  Tested, works.

Version 2.11. Tagged as 'Browse-2_11'

Detail:
  This check-in includes Phoenix version 2.11 (26-Apr-2005); only the
  debug and JavaScript builds of Phoenix have been tested and resources
  will definitely be out of date for other versions. The various "!..."
  scripts have been updated to require a minimum of 2MB with no maximum
  limit for building, as CC 5.60 is quite RAM hungry.
Admin:
  Phoenix 2.11 JS builds OK, works reasonably well. Many outstanding
  issues of course, as this is a very outdated browser now.

Version 2.09. Tagged as 'Browse-2_09'

Detail:
  This is in the middle of some load balancer changes, but I'm checking it
  in as there's a sweeping source code change to use DebugLib. See Global.c
  for full details. Temporary debug code for the load balancer stuff is
  currently held under undocumented area "test".
Admin:
  This build now identifies itself as 2.08 i2-4 and says Pace on the about:
  page. Run for some time with no unexpected problems. Tried a mixture of
  debug levels successfully.

Version 2.08. Not tagged

64-wide comments adopted throughout. All headers protected against multiple inclusion. Use of <> for external headers rather than "". For libraries, <libname/header.h> is used rather than relying on a complex include path, where appropriate. Move towards using external URILib rather than the local copy. Phoenix JavaScript build resources are the only up to date set currently so don't try others; more work still required on Makefile (e.g.

getting the ROM build working, and internationalisation issues).

Version 2.08. Not tagged

Header and footer support working a lot better than in the previous release. Could do with some code tidying, but little else to do.

Fixed a typo in JavaScript.c that stopped debug builds compiling,
and updated Trace.c to know about all current HStream flags bits.

Misecllaneous tweaks and fixes. Major addition is full header and footer support in the printing system - see the Phoenix Choices file for more information.

Only the Phoenix resources are up to date currently.

Long overdue check-in of intermediate browser build, from continued "out of hours" work. Forgot to add a few files last time too.

List dialogue box handler complete, and exclusion lists implemented
within the main browser code. Full documentation in Choices file.
Save routine knows all about it but is now getting very slow - must
come up with a better scheme; for now, it puts the hourglass on...

StripExtensions option controls auto stripping of filename extensions.

More sensible ancestor / frame selection for keyboard shortcut items
and the save dialogues - having selected a frame won't lock you into
it for F3 and related shortcuts now (input focus in URL writable ->
get ancestor details, input focus in frame -> get frame details). F4
works in frames. F5 now generally present for 'view source' with a
corresponding menu entry in the File menu.

Odd thing in later Res files; there's no action set for Adjust clicks
on the main ToolAction items in the button bar. Very odd. Nothing
appears to be set in v2.07 either, yet adjust-click works. Even
stranger. Anyway, added in the relevant event details (same as for
Select click in all cases) and this fixes the problem.

Background colours in the TABLE tag ignored the "don't print any
backgrounds" Print Style setting. Fixed. Meanwhile, the "black
text with no backgrounds" option wasn't getting this right either;
fixed this also.

Event logging implemented; HTTP errors and script output via.
window.print extension. No internal error output yet.

Faith:Never behaviour extended. If ever a server sends something with
no content type or an unhandleable type, the browser will try and get a
filetype from the URL. If it gets text or HTML, it'll render the file.
Else it'll save it. Hacks around IIS 4's lack of a content type field
in the Marketeye login stuff, and similar other slightly broken sites.

Intermediate check-in; building a browser from this gives you something between 2.07 and 2.08. Only the Phoenix JavaScript resources are fully up to date.

I *think* these are the changes since the last check-in:

When saved as a Draw file, horizontal rules were plotted one page width
too far to the right (wonder when that started happening?!). Fixed. In
addition, DrawFiles now accepted as OBJECTs - they weren't in the
recognised filetype list before. Doh.

Table size calculator tables_count_table would overestimate the number
of cells where ROWSPAN was present and there were other rows below the
one spanned. Fixed. In certain odd cases (e.g. optimised image exports
as HTML tables (!!) from the Gimp) this can save vast amounts of RAM.

Fixed problem where printing stops in the middle of a document. Redraw
engine pagination code was written in the days where lines couldn't
have gaps between them; they can now. If a gap fell at the bottom of
a page the engine would look down, see no line straddling or touching
the page edge, and assume there was nothing more. This case is now
correctly handled.

Made sure desktop and testbed Browse Res files had up-to-date Encoding
menus (v2.07 Phoenix has different menus from v2.07 Browse by oversight).

URL auto-completion piggy-backed onto manual completion code; any string
without '.', '/' or ':' in it gets run through completion to see if a
more meaningful item can be produced - "www" special cased out though.

New List dialogue box handler, used for proxy exclusions etc.
(incomplete), complete with appropriate Res file objects.

Tweaks to export rules in Makefile - ResJ source for JavaScript builds, all of User dir exported, resources rule exports About as well as User.

Handles images with a width or height of 0 specified in the HTML.
Previously went for a default size placeholder and changes to image
sizes and/or redraw problems could occur before/after subsequent
reformatting (involved trivial changes to image_get_image_size and
image_redraw_area only).

Default parameter HRs now plot properly in rectangular pixel modes.

Choices code updated to cope with the minimum font size, JS support,
watchdog on/off and timeout, Navigator object option added generally
(act even *more* like Navigator), image GC after fetch, and image
GC unused image / free RAM constraints.

Code in JSnavigator.c updated to obey new "act more like Navigator"
option (see above). Currently declares itself as version 3.0.

Resources for all builds are up to date. All links in default hotlist
verified and corrected where necessary, with several new links added.

This is Release v2.07. Not tested very much, sorry; YMMV.

Another intermediate check-in, resources may not be up to date; items most likely to be buildable are PhoenixJ and BrowseD. Done because I'm about to make some rather dodgy changes to code otherwise unchanged since the Customer browser and I may well have to back them out...

In Handlers.c now set the HFlags_HasBeenVisited bit of a token at the point
it is first clicked on. Means the link returns to a "visited" colour after
the highlight flash immediately. This will persist for as long as the browser
window is kept open on that page, though if the URL doesn't end up making it
into the history for whatever reason it would "unhighlight" on reload; fair
enough, really. The highlight is window-local, so there are no redraw worries
for other open windows with links to the same URL (though other same-URL
links on the same page aren't updated either).

All forms submissions force a reload (principally for eudoramail.com, but
many other sites have similar requirements).

!MkClean and !MkClnAll didn't correctly call the utility to strip Makefile
dependencies. Fixed.

On fetch closedown, fetchpage_preprocess_token could be called on a token
which had already been run through the preprocessor. Now checks the flags
word before proceeding.

Image RAM cache and garbage collection system implemented - see new Choices
file entries CollectAfter, FreeRAMLimit and UnusedImageLimit to get an
overview. This contains groundwork for JavaScript image array support.

More JavaScript support improvements. Any one window object will know its
parent, top, this, etc.; frames array working except for a frameset created
via. multiple documents; opener for something created with window.open is
currently not set and don't know why (property is being created, pointer to
valid object is held, but JS engine returns 'null'. Ho hum) - JSChain won't
work yet, then.

Everyone else seems to be checking lots of stuff in lately, so I've decided to join in. This is an intermediate check-in and so not all resources etc. will be up to date. You should be able to make Phoenix and a debug build out of it. As a reminder, to make a JavaScript build:

 * Build JSLib and NSPRLib. Recommend you leave -DUSEMEMLIB in there (as
   used by default) so you can watch it leak into a dynamic area... :-)
   If you do this, you'll need to build MemLib too, of course. If you
   do NOT use MemLib, *undefine JS_USING_MEMLIB in Main.c*!
 * Run !MkClean. This now strips dynamic dependencies from the MakeFile
   automatically, to save you having to do it yourself.
 * Run one of the TaskObey files with the "J" suffix, e.g. !DeskBrwsJ -
   this uses the same .o directory for object files and exports to the
   same position in the Targets directory as the non-JavaScript build,
   but it does produce a unique binary in 'abs' and symbols table in
   'syms'.
 * Sourcing an appropriate !Run (with increased WimpSlot value), !Boot
   and About resource is done automatically.
 * Some, but not all of the !xxxD (debug) TaskObey files will make
   JavaScript versions in passing - check the JSUFFIX value on the Make
   command line parameters in the file.

This'll only work on RISC OS 3.1 due to the use of MemLib.

Here's the change list:

Included MNG icons in sprites files; added Sprites23 for some builds.
Added in ANT URL file icon (b28) derived from URI file icon, because
the Save dialogue can need it.

No, you do *not* need to define the same keyboard shortcuts in each
frame since the ancestor keeps the input focus and we've basically
dropped non-nested Wimp support. Maintaining no less than 4 lists of
identical shortcuts was a pain. Some Res files now only have the
lists in the main browser window and button bar objects (these two
are both required still).

Ursula build Markers button arrangement changed from 1x3 horizontal to
2x2 tilted, as in Phoenix, by popular demand.

Couple of hotlist bugs fixed; dragging an item and deleteing it with
Ctrl+X didn't terminate the drag, and deleteting an item underneath a
menu opened for it didn't close the menu.

'SendReferer' option added to all Choices files, all set to 'always'.
Put just beneath 'Clone' as it refers to header items, though really,
both Clone and SendReferer should probably be in the "Fetch controls"
section rather than "Multiuser environments and proxying"! Front-end
control of this is available.

In image_export_original, save_save_source, save_transfer_source and
save_save_object, flex_set_budge(0) was called to lock the heap but the
return value wasn't stored. flex_set_budge(1) was then used to unlock
the heap. All calls now remember and restore the old value, which is
both safer in case one calls another and allows the flex_set_budge
call in Main.c to have an application-wide meaning, as intended.

Some restructuring to the data load and RAM transfer sections of
Protocols.c; remote hotlist builds wouldn't allow files to be loaded
to browser windows before, and can now drop URL, URI or text files to
the Open URL dialogue.

New option "MinimumFontSize", lets the 'size' attribute of the 'font'
element be overridden. Default value is 1, to allow the full range of
values for the attribute. Setting to 7, for example, would give font
size 7 text at all times. Another new option, "ToggleOnXOnly", to
make Toggle Size only extend the window vertically (with Ctrl then
being used to toggle to genuine full size, rather than vice versa).
All Choices files updated to hold both of these options; only the
first has front-end control available (see debug build Res file).

JavaScript Document object exists; frames array etc. working. Can now
just about use "http://www.acorn.com/~ahodgkin/jschain/" but it does
abort after a bit - problems with frames again, I suspect. Is is pretty
slow, too. Can now press Escape to terminate a script.

Main.c erroneously referred to Controls file entry "StopWebServe" as
"StopWebProxy". Fixed.

Keyboard shortcuts to raise SaveFile are now possible in a general sense;
the code before was in the ToBeShown handler and just checked for a parent
component of -1. It then assumed "save frame HTML source". Now there's the
savefile_raise_from_shortcut function, which together with the seven new
event codes in SaveFile.h allows saving of HTML source and frame location,
export of links, images, backgrounds and the page as text or draw, to all
be invoked by keyboard shortcuts. Some Res files have some of these defined.

In reformat_check_height, the first check to see if setpara should be set
references a field in tpLast without checking if it is NULL. Whilst the
'line > 0' check should mean that tpLast wasn't NULL anyway, a direct
call to the function from outside of the reformatter might have tripped
up on this - the check for tpLast != NULL is now made.

Adjust-click on close icon in window showing file: URL attempts to open
the parent Filer window.

Reformatter used to try and find a selectable token if keyboard control
was enabled in a really stupid place - could make reformatting become
very slow if no selectables were present, especially if the page had a
few tables on it. Preprocessor now does this (since it goes through all
of the tokens anyway), the reformatter just doing a last check to ensure
no frames have obscured the selectable and if so, it tries to move it.
Done in the reformatter as generating a line array implies the data really
is visible.

Ctrl+Tab URL completion now builds a full list of matches from the hotlist
and history and can cycle through them (Ctrl+Shift+Tab stepping backwards).

Will give a real error rather than just "Data Abort" if it goes wrong
now. Someone somewhere is setting bit 30 of the error which confused
the replacement signal handler. Flag bits are now masked off (as they
should've been to start with).

Added capability to send Referer headers, together with new options to allow this to be sent: a) Always, b) Never, c) when the URL referred to is an http URL.  Default is c.  There is no frontend editing capability for this option.  This addition means that various counters and sites that rely on referer to indicate a resource upon which an operation is to be carried out will now work (eg. rating a web site on Geocities).

CVS crashing. Some of the Resources may well be out of date due to CVS
locks being in place after earlier server-end core dumps, which I can't
remove myself.

I'll try and check one file in at the end with the full change log so
people know what's happened (it's reached about 16K...) - I'll make
that the TaskObey file '!All' in the top level directory. So for the
full log, look for the changes on this file.

RefoKeep and RefoHold options added to, respectively, try and maintain
the line at the top of the visible area when reformatting, and not shrink
the vertical extent at the start of a reformat to try and avoid flicker
to the top of the page and back down again when RefoKeep is on. Choices
front-end implemented, which also allows RefoWait and RefoTime to be set.
Unfortunately for various reasons this doesn't help the page jumping when
unsized images come in (but RefoHold can improve matters...) - roll on
the image history.

DragToScroll and NoScrollBars options added for frames; included new
pointer type, Mouse_Shape_DTS, so relevant Controls file entries done
and Sprites[22] files updated as required. Noticed some builds have
a low-res ptr_link with a mask - mask removed.

Named anchor following fixed up somewhat - anchors near the bottom of
the page shouldn't be displayed, and then pulled down when the fetcher
releases null polls and ensures the y extent is correct (this through
implementing the min_height field in the browser_data structure).

RefoHang was never implemented and there seems little point to it now,
so the entry for it has been removed from the global choices structure
and all Choices files.

Markers menus should work properly now (in last check-in they would not
update correctly if Adjust was used on the entries).

URI handler usage now a lot more sensible, with configuration of how the
browser uses the module from both a Utils menu submenu (sic) and the
Choices dialogue.

Slightly dodgy 'hang around waiting for user input' stuff for the Cookies
dialogue box: All fetches are suspended; the fetcher remembers some info
about its state at the time the cookie came in, and restores it later; it
will only do this for one fetch at a time. It's necessary to single-thread
the fetcher at this point anyway, since other fetches may have a
dependency on the cookie that is hanging in mid-air at that point. As part
of this, some of the fetcher code has been split out into separate
functions (to try and 'black box' the code a bit). Anyway, Cookie Query
dialogue box now implemented with appropriate Choices file entry and
UI work in the Choices dialogue box.

Phoenix build Choices rearranged. Can now choose when the image history
is saved from the front end. Added also MSIE 4-style table option menu
for JPEG support (OS only, OS if it can handle it, internal only).

Should be a bit faster at loading the history - though 95% of the time
is spent in SWI URL_ParseURL. URL descriptions are stored more
efficiently as part of this - one malloc block instead of several
small blocks. The minimum block size for malloc blocks typically leads
to a significantly smaller startup wimpslot depending on the visit
history size.

Nasty bug in image system fixed. If an image size came in and a reformat
was to take place, the line the image lies in is found and the reformat
progresses from there. Unforunately, this didn't check to see if the
token can't be found in the line list, so it'd reformat from the top
of the page...! This would happen if, for example, an image halfway down
the page came in whilst a reformat for an image higher up had just begun.

In Choices.c, made choices_set_timetype_field, choices_set_uri_field,
choices_set_plugin_field, choices_set_cookie_field, and
choices_set_jpeg_field static (so they're not declared in Choices.h now).

Two memory leaks plugged in URL comparison routines in URLutils.c
(calling free() url_description instead of urlutils_free_descripton()).

Client pull reload handler was setting the reload flag if reloading
the same page, but forgetting to turn on reload_lock so
fetchpage_postprocessed was clearing the reload state... Similarly,
Ctrl+Shift+SELECT-Click on a link when the Controls file 'UseSmall'
entry is 'no' would not have reloaded as it should. Both fixed.

Frames shouldn't be so keen on acquiring horizontal scroll bars and never
letting them go when their width is decreased now. Frames set up for
'scrolling="yes"' will not start with no scroll bars and then gain them
shortly afterwards, causing flicker and two reformats - they'll start
with, and continue to hold, both scroll bars.

Pointer shouldn't flicker when over a frame border whilst other fetches
are progressing now.

This is NOT a 'final' version of anything in particular. I'm checking it in as I'm about to start playing around with low level window handling

(as part of the thing mentioned at the bottom of this log) - this could
screw things up quite badly if it goes wrong! =8*P

Consequently, I advise you not to check this out over your working sources,
and preferably not to check this out at all.

Markers system - events defined in MiscEvents.h will make Browse remember
where it is on the page. This position can be jumped back to later.
Some builds will have defined keyboard shortcuts Ctrl+Shift+F5 through
F8 to set a marker, and Ctrl+F5 through F8 to jump to a marker.

The front-end for the above now has gadgets 0x80 upwards on the Toolbar or
a set of menus (see Menus.h). Noticed an omission in copy_toolaction_info()
(didn't copy the gadget state) in passing; fixed.

browser_top_line() now works properly, as part of the above, but it'll be
slower than before. If flagged to only find a complete line, it'll do just
that, but whereas before this would require any tables that it looked
inside to be wholly visible, tables can now be partially visible and have
lines inside that are fully visible. This should help the Find function
too. There is a new call, browser_top_line_offset, which works as
browser_top_line but also returns a vertical scroll offset in the found
line (used for more accurate marker position). browser_bottom_line[_r]
turn out to never be used, even by the keyboard control routines, so they
have been removed from Browser.c (rather than spend a lot of time and
effort fixing them).

browser_show_token erroneously subtracted 1 from a particular coordinate
when calculating the y scroll position, which could lead to single pixel
page creep using the markers system. Corrected.

The View Resources button (see Toolbars.h) has been finally implemented,
insofar as it fetches the resources file to the current browser page (or
to a new window if Adjust is used, Controls file settings permitting).

menus_toggle_bars did not take account of the toolbar lower window border
edge correctly. It does now.

The reformatter has a prototype system to keep the vertical page position
when reformatting. This was coded about 5 minutes ago, and is not likely
to be reliable...

Some compile-time hacks in place to use MemLib, a dynamic area based
malloc replacement which shrinks its heap when possible. All builds
have these switched off at the moment. Seemed to work with just Browse,
though there would be problems with message blocks stored in dynamic
areas because of the Wimp's '&3800000' check - however, it failed when
HTMLLib was made to use it, too. Don't know why yet.

ItemInfo.[c/h] source added, with Res file additions for testbed Browse
and Phoenix.

Small fetch windows now work properly regardless of toolbar settings
in the Choices.

Reload now reloads all images too, rather than only reloading them for
as long as the main page was being fetched.

Added a simple 'Find' facility.

Realised that event handlers in eventlib are called in reverse order
of registration, so the miscellaneous event handler is now registered
first rather than last.

Multiuser code added (most only active if SINGLE_USER is undefined). As
part of this, hotlist code now knows about read-only items (done for the
Customer-style 'Resources' file, but works generally anyway).
handle_add_hotlist doesn't try to save the hotlist itself anymore (the
hotlist_add function does all that through hotlist_modified anyway).

Customer build Choices and Controls updated slightly (e.g. ClaimHelp
off, hotlist to save on quit only).

Customer build now uses Phoenix-style buttons. Sprites files which
worked at the time (but will probably be out of date now) and included
most of the original Customer-style sprites are in
'Utils.Icons.Customer'.

Choices, Messages and Res files for all builds now stripped down to only
single user items or single plus multiuser for Customer build and testbed
build. Before, all contained a few multiuser bits in at least the Choices
file if not more.

Grammatical error ("Fetching frames contents" (sic.)) corrected in
default message, Toolbars.c, and all of the Messages files.

Customer build brought back to a servicable level (including
implementation of the Find dialogue box with animation and fixing
up authorisation and 'Stop' state in the tristate). Quite a few
missing #ifndef REMOTE_HOTLIST bits from hotlist code added...

Customer build will not use <Choices$Write> or Boot:Choices for any
file finding now. UseProxy defaults to 'yes', MaxImages to 2. Res
file includes Proxy Address setting (save_save_choices() now writes
the ProxyAddress line).

Precautions taken in table code to avoid divide by zero errors.

Framesets defining more frames than the frameset implies, for whatever
reason, should never cause a crash now - just report a 'Frames definition
is badly nested' error (if STRICT_PARSER defined). Along the same lines,
in a single document defining a set of nested frames, two /FRAMESETs in
succession could cause a fairly nasty crash. Fixed.

TIFFs do not get loaded by double-click now.

If holding down SHIFT to save a link contents to disc, you can also hold
down CTRL to bypass the cache (sets the browser's reloading flag). Noticed
when testing this that windows_create_browser didn't take account of the
Controls file 'UseSmall' entry when adjust-shift-clicking on links. It
does now.

There is now a complete and up to date set of interactive help messages
built into the Ursula, Customer and Phoenix build Res files.

WindowManager 3.98. Sets URI handler environment variables for
http, ftp and gopher.

Fixed 'doesn't reformat for unsized images' bug - only happens when the
deferred reformatter is enabled, hadn't remembered to check this in my
debug build where this is turned off. Oops.

Caret position in forms could get left behind despite attempts to rectify
this in v1.31 - now fixed (and faster, fortunately).

Hourglass + percentage displayed for History and Image History when
loading - it can take a while for very big histories, though in
practice you only see the visit history loading (has to do a lot
more work, and is thus quite a bit slower than the image history).

POST forms worked when targetted to frames, but were broken when
not targetted! (Forms data inherited from one browser to the same
browser; ended up freeing the flex block...). Fixed.

Now support 303 response code (redirect to GET). Treated as 301, i.e.
not support if STRICT_PARSER is defined, otherwise drops through to
the 302 handling code.

Pointer shouldn't get stuck in odd shapes when going to a new page now;
it gets reset to a standard shape every time the null handler that
checks the position is called, though (whether or not the handler thinks
the pointer is over a different token, if that token is NULL, it sets
the standard shape). A possible work around would be for a browser to
remember the pointer shape too; that's for the future, though.

Early stage table formatting functions could blow themselves apart if
tables_count_table decided there were no rows, columns or both. A
net table size of zero cells is now dealt with; slow, partial table
fetches in multiple windows with image loading turned on will now
*hopefully* be stable, where v1.31 would have bombed out repeatedly.

A nested frameset within one document will now inherit the border
width (frame spacing) and border colour of its parent. This is done
by copying the maxlen and indent fields of the parent token over
the child, and note it's done in the browser (fetch_preprocess_token),
not HTMLLib.

Border colour on a FRAMESET now used, with the first colour on any
FRAME within it overriding, as in NN 4 and MSIE 4.

<LI> bullets really do stick to the text next to them now (I'd done
that in an experimental piece of code and forgotten to merge it back
before the last check-in).

Browse$HotlistURL/URIFile and Browse$HomeURL/URIFile now work from
_TaskName in the Messages file, and are thus of the generic form
<App>$HotlistURL etc. - Docs.Notes and Docs.User updated appropriately.

Event 0x11d00 through to 0x11d7f will make the browser look up Controls
file entries 'JumpTo00' through to 'JumpTo7f' and read a URL from them.
This will be fetched in the ancestor window of the source of the event,
or a new window if such an ancestor can't be found [for Daytona demo].

NB: Nasty frames-related crash at http://www.teledanmark.dk/menu/start.htm
is *not* fixed in this source. NOBR is not supported.

Check for WindowManager 3.97 and ensure Unicode$Path is set in all !Run[D] files, don't set the Alias$@PrintType_FF4 variable, and updated

Customer build ROM obey file variants. Various other changes to
the Run files for new module versions, updated paths to support
new positions of choices, hotlist and histories (see later), etc.

!Sprites[22] files hold small !app icons for some variants, and
an ic_browse sprite. Some variants now have a Sprites and Sprites22
file instead of just Sprites, with the former containing various
mode 12 or 15 specific sprites.

Text files dragged to the URL writable are treated as ANT URL files. This
relies on URLBarWrit (Toolbars.h) being a unique ID, which it should be,
but beware of the Hotlist and Choices numberspaces...

INPUT TYPE=BUTTON supported. Form items without a FORM tag are now shown
(as MSIE 4, but not NN 4).

'*', '-', '@', '_' and '.' are not escaped when submitting forms now. The
Web interface to the IMDb now works.

INPUT TYPE=HIDDEN items will not affect the line height anymore - so
http://www.hotmail.com/ now has correctly aligned writable icons, for
example. Similarly, TAG_FORM and TAG_FORM_END items could push up
line height and don't anymore.

HRs with a specified pixel width will now influence the size of a table
cell (they didn't before).

BRs now checked by tagno field when the browser needs to know something
was an actual BR tag rather than just a line break signal, and by the
style bit entry when only the indication of a line break is required.

Table widths of 0 or 0% are ignored.

Trace.c updated to report height and background fields in a table_stream.

fm_putsl() writes a terminator into the string; the Forms.c routines were
calling this for displaying INPUT TYPE=PASSWORD fields using the FE_PassCode
literal string (a line of stars). This write into a read only data area
would make the debugger fault the access. A local char array is now used
instead, to get round this (note the use of var[]=literal rather than
var[sizeof(literal)]; strcpy(var, literal) due to some weird compiler bug
that copies the wrong thing into 'var' under some (undefined...)
circumstances).

Text areas don't scroll back to the top line when clicked in anymore;
single line writables don't scroll back to the left either. When
reentering a text area from 'above', the caret appears at the top line
rather than 'somewhere further down'...

ARROWS_MOVE_OUT compile time option at the top of Forms.c defines whether
you must press Tab/Shift+Tab to move between writable fields in forms or
if up/down will drop out of them, though if keyboard control is on this
is enforced (or you get trapped inside the form!).

urlutils_filetype_from_url now uses MimeMap module.

If fetcher is told a page is text, it'll check for a filename extension and
may choose to use this instead (e.g. it may find it's HTML instead). This
is to try and get around duff servers... (e.g. http://www.batalarms.co.uk/).

Save dialogues shouldn't flicker when options that don't change the
filetype are selected (before, the draggable sprite was always reset for
each selection). Noticed the erroneous setting of a static variable in
SaveFile.c by a call to this by SaveObject.c, and so added a flag to
savefile_set_filetype to deal with this - would have been possible to get
the wrong filetype sent to applications or at best the wrong filetype
sprite in the dialogue without that.

The caret shouldn't jump out of a form back to the URL writable if the page
reformats now.

Table background colours now supported (as in the colour you see in the
border space if the cellspacing is large enough; this is as in MSIE, not
as in Navigator). Drawfile output routines updated accordingly.

Corrected erroneous use of wimpt_dx() / wimpt_dy() in a couple of places
in Images.c, which meant that (say) 1x1 images didn't work correctly in
medium resolution display modes.

Now have support for save as text (component ID and event 0x12) and save
as Draw (component ID and event 0x13) buttons. Dubious conditions for
greying and ungreying the print, save source and view source buttons and
menu options sorted out as part of implementing the same for the two new
buttons; added greying out of their associated menu items in passing.

Turned kerning on in draw file objects (does mean a rather heinous
increase in file size, but this is the only way to ensure the draw file
matches the visible page).

Comments before functions in SaveDraw.c are now complete and up to date.

Image and visit histories now generate a crude hash number to speed up
searching for items. It does give a speed increase, though it's a
disappointingly small one.

Issue of left/right margins and cellpaddings sorted out. Now have
redraw_left/right_margin for finding out the basic gap you must leave.
redraw_left/right_gap then gives any extra indentation for LI, BLOCKQUOTE
or whatever. The last two can be subtracted from the display width to
get an available page width for any section of text. Note that
redraw_left_gap replaces redraw_margin. The redraw_start_x function
uses the above to work out where a line's left hand edge should be,
taking account of left/right/centre alignment. HRs have been fixed now
(they were quite broken in v1.30, I think) based on this new model and
the behaviour of MSIE/NN 4.

Fixed width of cells with no contents - cell padding values wouldn't
have worked properly as the reformatter returns 0 rather than the left
hand margin size if given no stream.

Removed FM_Absolute flags for Font_Paint (spotted by DBrown) - sets bit
2, which is reserved...?

IMG width and height in % terms now works correctly; a % of available
width (after margins and indents) or height on the main page or for
a table cell, if the image lies in one. Because of the chicken-and-egg
problem with the latter, the cell must specify a width and/or height
for things to work properly. If this is not done, you'll usually end
up with a 1:1 scaled image (as in Navigator 4, rather than ending up
with no image or even no cell (!), as in MSIE 4).

HEIGHT attribute on a TABLE tag is supported, but only in a crude
fashion; the extra height (if there is any) is distributed over the
rows in a linear fashion. This is probably all you have to do in
practice, but I haven't checked. To maintain a notion of min/max
height as well as width would of course require a great deal more
work...

If using client pull to reload a page with a fragment ('...#name')
specified, then the reload wouldn't work on the same page; it'd just
jump to the fragment position. This won't happen if b->reloading is
set now (so works in conjunction with client pull on the same page
forcing a non-cached fetch). Similarly, if POSTing to such a URL,
a fetch will proceed (both these fixes done originally for
http://jupiter.beseen.com/chat/rooms/g/1678/).

browser_inherit split to browser_inherit and browser_inherit_post_data;
the code for the latter didn't clear any post_data in the child before
copying from the parent either, and could cause flex errors (now fixed).

Res file for Ursula ('Desktop' Browse) build tweaked - bits in the
font choices dialogue renamed, and button bar rearranged to hold the
new Save As Draw button. Other builds have had Save As Draw and
Save As Text buttons added, or not, depending upon availability of
suitable sprites, required UI simplicity, etc.

Now have:

  Browse$ChoicesFile
  Browse$ControlsFile
  Browse$ChoicesSave
  Browse$ControlsSave

(the last two are new) for loading and saving of the Choices or Controls
files. If unset, <App$Dir>.Choices or <App$Dir>.Controls will be set.
E.g., you could set Browse$ChoicesFile to be:

  <App$Dir>.Choices,Choices:WWW.(app).Choices

for loading and

  <Choices$Write>.WWW.(app).Choices

for saving. (The browser never saves Controls at the moment, so the
relevant variable above isn't effectively implemented, but could be
in future). Similarly, to support asymetric loading/saving of the Hotlist,
there are HotlistSave, HistorySave and ImageHistorySave entries in Choices
to complement HotlistPath, HistoryPath and ImageHistoryPath (which are used
for loading). save_save_choices will create directories as needed to obtain
the given path (and has also been fixed in various areas that hadn't been
tested out until now; e.g. zero termination of the AppName$ChoicesFile
variable expansion...). !Run[D] files updated appropriately.

Table widthing code rewritten. Slower, but a lot better on the whole.
Still has some problems - still needs a final 'make sure nothing is
below minimum width' scan, which it should be possible to do without.
No time to fix this at present!

The reformatter will now 'glue together' an LI token followed by any
non-LI token; so a bullet point followed by an item should not be able to
have a line break inserted after the bullet because of very tight width
constraints (it could before - yuk...).

'about:' brings up a page about the browser and any Plug-Ins, as with
Navigator (for example).

URI files support titles, as per spec. version 8. Saving a current
location to the Hotlist will thus give a sensible title now (unless
you're in a frame, so there's no title to get...). Of course, v1.00
files without a title still work.

Note that NOBR is *not* supported in this build and this combined with
the new table widther may cause problems on some sites (e.g. Microsoft's
home page!).

Fixed some glitches in the modified status bar code (e.g. status inference wasn't working properly).

Shift+Toggle size always opened to not obscure the icon bar. If CMOS is
set to always show the icon bar, then Shift+Toggle size is meant to
reverse sense and open to absolute full size. It now does this.

!Run[D] files now require URL 0.22, HTTP 0.64, FTP 0.22, Gopher 0.08
and File 0.32.

Minor overhaul of 'Docs.Notes' (with 'Docs.User' similarly updated) to
include a few new bits and pieces.

Timeout values of 0 now mean 'forever'. Plug-in status messages now have
their own timeout setting. New Messages token 'Actv' for extra info when
a status message times out and the status line drops to 'Viewing' or
'Ready' when there is still a Busy state registered by the Plug-in.

Small Fetch windows don't become visible briefly for Plug-in fetches
when the fetch is complete (for SeeFetches:no, where these windows
should be hidden all the time).

WebServe may be controlled through the Browse front-end via.
Wimp_MAppControl reason code 4 (Wimp_MAppControl_Configure). Note the
renaming internally of 'WebServ' or 'WebServe' has been changed to
'Proxy' (with lower case equivalents where relevant); proxy name
and starting details come from the Messages file 'ProxyName' and
'ProxyComm' tokens. More in 'Docs.Notes'.

Res files updated for image history and PRE/TT font aspect ratio
choices. 'Don't expire' labels changed to 'Expire' (oops, didn't
notice the change in the development Browse's Res file when I
updated all of the others until now...).

When printing, Wimp_PlotIcon appears to ignore R4 and R5, plots
'somewhere' on the page, and tries to get the sprite from the global
pool. This latter part normally causes an error to be raised; though
on my machine I just get a corrupted error message. The Desktop font
gets lost at this point too. All have yet to be fixed; as an
interim work around, Wimp_PlotIcon objects are never drawn at all
if the global 'printing' flag is set.

Message_PlugIn_Busy. Plug-in code more robust when given invalid
browser instance handles by the plug-in.

Line spacing is now calculated on the basis of the normal style base serif
font, with all other fonts being forced into that line height. This does
mean that an unusually tall (say) sans serif font may get clipped. It
appears to be the only way to get around wildly different baseline
depths returned from the font metrics - you can't work out line spacing
based on each different font style; the line spacing will vary.

Table heighting (as opposed to widthing...) improved considerably; rowspan
can no longer cause very tall cells in odd places. Having trouble getting
rid of the single pixel breaks between vertically adjacent cells, though
I've not tried too hard. Widthing, though, seems fairly badly broken at
present... :-/

Set/clear of page_is_text flag made more robust (it looked as though there
was the potential for this to get stuck in a set state, though I've never
see the front-end behave in a manner which indicates this is the case).
The reformatter will now decrease leading if this flag is set (plain text
pages look daft with a line spacing that is OK for 'rich' text pages).
No reformatting is done if the page width changes by dragging on the
resize icon, though toggle size / full screen will still reformat even
if the contents are only text (browser needs to sort out various width
flags at this point).

Cut down on excessive redrawing when reformatting due to a change in
window dimensions is not done. If display_width hasn't changed, then no
redraw is needed. If this causes redraw problems, then whatever is
changing display_width needs investigating. It shouldn't be kludged
(basically) by forcing a redraw instead of a reformat.

TT/PRE/etc. text can now have a non-100% aspect ratio. 80-90% looks
best (ArcWeb, for example, uses 86%). New option 'TTAspect' in
the Choices files.

Debug builds link to a non-debug Unicode library now; stops stderr
being dumped to the bottom left of the screen if you've not redirected
it in the Run file.

RISC OS 3.1 seems to need more initial WimpSlot than later OS versions.
The 64 deep nested table set gives a 'No stack for trap handler' error
(which it really means in this case!) without 800K, even though 3.71
is happy with just 640K. So, the !Run file checks if Boot$OSVersion
is exactly 300, 310 or 311, and sets the WimpSlot accordingly.

!Run[D] files now require latest fetcher module versions (URL 0.21,
File 0.31, HTTP 0.58).

Image history - sizes of images are remembered for future reference (if the sizes aren't specified in the HTML, they can be looked for in the image history instead to minimise reformatting requirements). Choices file options ImageHistoryPath, ImageExpiryAge, ImageMaxSize and

SaveImageHistory added to support this (all have a direct analogy to
the global History items of the same name after removing 'Image').

Text area items are now the correct height for the number of rows
specified in the HTML, don't scroll a line too early, and have the
caret placed at the start of the text when moved into from above
or at the end when moved into from below (rather than always at
the end, which was behaviour inherited from single line writables,
where this is desirable). The top of the text area is aligned to
the top of any line of text on the same line, with the text area
dropping below the text, rather than the bottom of the area matching
the text baseline and extending upwards.

Filename extensions for download files are only stripped if an
attempt to convert to a RISC OS filetype through the Mime Mapper module
does not return an error or Data (0xffd) filetype. '.cgi' is a special
case which is always stripped.

Altered heading styles - all are bold, none are italic, H3 is as big
as H2 was, H2 is a little larger, and others scale down to H6 being
the size as normal text (but, as I say, bold).

Sorted out tables and forms. We can just look for tagno=TAG_FORM, and
get rid of the wobbly form_flag; also discarded the redundant
reprocess_table flag in fetch_preprocess_token. Two separate forms
in consecutive table cells (for example) which used to fail - they
were submitted as one single form - will now work correctly.

Fixed nasty bug in FontManage.c where font size 7 would intermittently
fail. The stupid font sizes that it could ask the Font Manager for may
be responsible for the occasional Font Manager crashes that have been
noticed. Array for font sizes was declared as [Limits_FontSizes], but
indices 1 to Limits_FontSizes are actually used - so needed a '+ 1'
in the declaration... :-/

Replaced the case insensitive string comparison functions in Utils.c
with more efficient versions by S.Brodie.

MAXLENGTH specifier in INPUT tags is now supported. If unspecified or
specifically zero, the browser overrides and allows any length.

Adjust-click on forwards/backwards buttons did not work in the intermediate
build, and now does.

Adjust-click on form submission buttons where the submit method is POST
will now work correctly, as the new view inherits the extradata block
of the old. Failure of this is signalled through
make_no_fetch_memory_error, code 16 (see updated Errors file in Docs).
Note the name change of extradata in this context; more details below.

The passing of forms POST data and extra headers for sending in an
HTTP request via. the URL module was all done through pointers into
flex blocks, and was therefore very unsafe. All relevant functions now
use pointers to pointers to the data.

To remove confusion on the umpteen uses of the word 'extradata', the field
in browser_data has been renamed to 'post_data'. The 'extradata' parameters
used within FetchPage.c were all disconnected from the extra header info /
form POST data stuff that extradata is usually associated with, and have
thus also been renamed, in this case to 'appnddata' (Append Data).

As well as X-NoProxy, the browser sends the 'proper' HTTP headers
Pragma:no-cache and Cache-Control:no-cache.

A redirection from a POST request was not handled correctly; despite
what HTTP specs say, you're supposed to use GET for the new URL. The
browser was, but when it chopped off the redundant header data in the
request didn't terminate it and left Content-Type in anyway...! Fixed.

Ctrl+Tab implemented - URL completion. Comes from the hotlist URLs,
hotlist titles, history hosts, paths, full URLs and lastly titles.
See code comments for more (history_find_match, hotlist_find_match).

TableSupport option added to Choices; it is read, can be set by the
front-end, but doesn't actually do anything else yet.

Reversed Choices' semantics on 'don't expire by...' for History. Added
'needs_redraw' flag to choices_get_contents so that, for example, if the
table border types change, browsers get redrawn.

This is an intermediate check-in to allow work on Choices for the new table options and History choices as detailed below. Res files are not up to date except where indicated and there are several known bugs that will be fixed before the 'final' v1.27 is created. Any work on resources should only be done for the testbed !Browse.

Client side image maps implemented. There is code to draw highlighted
borders in CSIM.c, but this is not wired in yet; other than that,
the implementation is functionally complete. As part of this, centralised
the fetching of a targetted URL taking into account user request of a
new view and full screen mode, in fetchpage_fetch_targetted. The forms
library now uses this too, so form buttons respond to both adjust-clicks
and TARGET attributes.

Fixed APPLET handling where '.class' isn't present in the CODE attribute.

Paragraphs squashed at the top of cells/pages - browser would insert white
space before.

Now append a ' ' to the end of History menu items to prevent the Wimp
thinking the end of entries represents a keyboard shortcut (e.g. 'Home').

Netscape's handling of 'meta http-equiv="refresh"' is to start counting
when the fetch has completed and everything else has died down. The browser
will now not start counting until the animation handler is deregistered
(so formatting is complete) to show similar behaviour (note that this
checks the main handler, not the 'idle but returning to first frame'
drift handler).

URLs from requests for fetches by Plug-Ins are now relativised.

Page width change tolerance prior to reformat upped from 16 to 32 OS
units. Hoping to provoke a loosely connected bug with this change!

TableOuter, TableInner and SeeFetches choices added to all Choices
files, with appropriate loading and saving code in Main.c and Save.c.
AuthorFTP and AuthorFSh messages added for FTP authentication, and
dialogue handling code (the component in FetchHTML.c) updated to
recognise an FTP fetch and alter the dialogue presentation
appropriately.

All Messages file version numbers taken up to 1.27 (20 Nov 1997).

Following a UseNet suggestion, Ctrl+Toggle Size will increase the window
size to fill the screen vertically only; horizontal size/positioning is
not changed.

Shift+Tab in the URL writable will cycle through alternative fetcher
protocols (from both the Controls file and checking the fetcher modules
are actually present).

Hotlist doesn't require '://' in URLs when loading HTML, just ':/' - so
'file:/' URLs now will be reloaded correctly.

History system rewritten completely. GHistSize and VHistSize options
removed, and replaced by MaxSize and ExpiryAge. Now have global history
menus with most recently visited items at the top, and local history
menus which reflect the path that forward/back buttons would take.
Browsers are robust to background expiry of the History though this is
not implemented - date expiry and size checks are carried out on
history_record only. This does mean that with two windows open one could
have the history expired underneath it whilst another fetched, though;
the code handles this and update toolbars (greying items) as necessary.
It is possible to have the history limits so tight that even one entry
will not fit and again the code copes with this, though values read
from Choices are limit checked to ensure rather more useful results!

Implemented 'Save' button in save dialogues. Remembers pathnames and just
replaces the leaf now (hard coded exceptions for <Wimp$Scrap>... and
<Wimp$ScrapDir>...) - it did before, but only if you'd typed the path
in. Not many people did, given that you couldn't press Return or click on
a Save button to use that path...

In a similar vein, files of type Data or DOS will be checked for a '/xxx'
type extension and the MimeMap module will be used to find a more meaningful
filetype. If this can be handled, the file is loaded. This only works for
files dragged to the browser - the behaviour with inline data in web pages
will depend on the File module, and similarly, if File doesn't spot what is
going on and claims that the object is data, the browser will just open a
save dialogue for it.

!RunD files taken up to 3072K WimpSlot.

Hotlist's saved HTML page title wasn't internationalised - is now. This
opened up a significant can of worms; on file write error, the file would
never be closed, and if a caller of the save or load functions passed
in a filename held in the global Messages lookup buffer then subsequent
lookups in the callees would corrupt that filename. All sorted out now.

Local (not very useful) or global (useful) histories can be saved as HTML,
which opens up the possibility of sending your history to the hotlist
by saving to it. Local and global histories can also be emptied, though
this is probably not a feature that current release Desktop browsers need.
Inheritance of local history and certain UI features is now done more or
less for all cases where one browser window spawns another, too.

Vertical alignment on images is rather less ropey than it was (e.g.
ALIGN=TOP stands half a chance of working) but is still far from perfect.
This was part of fixing a nasty little bug in Redraw.c's setting of
an image position via. image_set_token_image_position, which was making
(amongst possibly many other things) client side image maps fail.
Image update where images had large borders was affected by a similar
problem too (more cans with more worms...).

Fixed image background filler functions; two problems. When cross
referenced images were replaced by base images in a browser because the
original owner was closing down, the original owner browser would stay
registered with ImageLib. Fixed; secondly, when images were deleted from
the image array causing those above to be renumbered, images registered
with ImageLib did not have their numbers updated (this was the one that
lead to the visible drop out of background images with PNGs on the Acorn
Internet home page when there were two views of the page and the first
was closed). This is now also sorted out.

Stopped UNIFONT forcing system font use and added calls to Font_WideFormat.
Made sure the system font option is read before fm_init is called!

User agent string now set if Netscape faking is disabled (format used is
"Acorn Browse/1.26 (RISC OS 3.71)".

Removed 'The Onion' link from some Hotlist files. Time showed that the site wasn't entirely Family Friendly (TM)... Removed Shift Control (it's gone offline now), and corrected the Telegraph URL from ...the-telegraph...

to just ...telegraph...

StrongHelp manual generator now tries to work out the number of lines in
the table on the root page more intelligently.

Plug-in support extended to handle Shockwave. Quite a lot of underlying
work for this, including a pseudo cache system for temporary files.

Bug in redraw routines: they plotted background images within table
cells, when nothing should have been drawn. Oops. When background images
in cells are properly supported, this can get sorted out.

Tweaked vertical plot position of HRs (up to 4 OS units too high before due
to rounding).

Various Res file bits and pieces, Ursula build taken up to v1.26 beta
for release on the Browser site. *Note* not all resources are up to date!
This will be done after AW97.

Various fixes in the code required for Shockwave support (many invalid assumptions about the OBJECT tag structure). Not finished yet though.

Played around with signal handling 'n' all that to try and get sensible
errors reported for aborts etc. using code by KBracey. Need a ROM patch
for _swix on RISC OS 3.7 upwards (or a local fixed copy of _swix),
otherwise should sort out most of the problems seen (mostly 'no stack
for trap handler' errors and a distinct lack of a register dump).

Plug-In view on redraw / ASAP choices now work as they should (ASAP
was previously broken).

Version numbers in Messages incremented to 1.25 (23 Oct 1997).

For Plug-In support, created new source file RMA.c/h to handle RMA
claims and releases, in an attempt to ensure leakage never happens.
As such, this source is *slightly* more advanced than that in the 1.25
AW '97 build, though functionally identical. Well, that is, at least
you can confirm zero RMA leakage with '-debug LMem' in TRACE builds now!

Intend to do a consistency check on comment syntax in all sources
shortly - I need to rebuild my StrongHelp manuals; can't keep track
of all of these new functions...

fetch_get_raw_data will notice if up->fetching is zero and return a 'finished' status rather than trying to continue reading data for the fetch. Fetches should never fall through that far but at least it will cope if they do.

3D table borders are now supported. 2D borders are used if the
inter-cell spacing is too small to fit the borders in (display resolution
dependent) - the external table border is 2D if the internal borders are,
else 3D. For cellspacing of 0, internal table borders must plot over the
outer edge of pixels inside the cell; for all greater spacings, the
borders take up all or part of the gap between them. The external border
will always fit around the outside of the cells, including the
cellspacing value in the gap between the outer cells and the border.

Anti-alias colour for placeholder ALT text was incorrect. Fixed.

I'd changed 'point' to 'points' in some of the Font Choices dialogues;
now changed back to 'point'.

The routine to find out how large an otherwise unsized object or image
placeholder based on its ALT text has been centralised in Reformat.c,
so that the image and object routines can both access it without
code duplication (this means non-image objects will now have the correct
size if they contain ALT text, rather than assuming a standard default
size as before). ALT text in images that were also objects was never
plotted either, though the placeholder size would have been correct.
This has been fixed.

Main.c, so the last log was incorrect; Navigate menu items wouldn't have
been greyed out. Probably a(nother?) CVS update screw up on my part; now
fixed. This sort of thing is happening far too often...

Font manager would crash in system font or if a font face was not found
in the previous release - that hacky business of returning weird font
handles when system font is to be used instead ensured a rather less than
valid array reference on behalf of fm_claim_basic_typefaces.

Added in a few more calls to the 'check the button bar' routines, to
ensure that things like Stop are greyed/ungreyed when needed.

Cellpadding code could lead to rmarg overlapping lmarg, or the sum
being greater than dwidth, or something like that (!) in the reformatter.
Anyway the results were unpleasant; this has been sorted out by range
checking right and left margins w.r.t. display width in the relevant
section of the code.

People who specify 'td width = 2000' in tables expecting to get something
sensible now do, though I was half inclined to leave it alone... I can
only assume that they don't know about % specification or it didn't
work in their browser at authorship time, and the huge width served as
an attempt to get the table to fill the available window width. Anyway,
the table reformatter spots when the maximum width a cell requires is
less than half of what it asks for, and ignores the width specifier if
this is the case.

Implemented font size choices.

Now handles PARAM tags. Sorted out Plug-In bug that was related to Java setting a 0 by 0 graphics window before calling Wimp_Poll (fixed in Java).

Implemented queue for Plug-Ins so multiple broadcasts aren't sent for
several Objects in one data chunk.

Added Docs directory with some documentation in it. More things to keep
checking for stylistic consistency, horray ;-)

Corrected !Run[D] for Ursula build to need AcornURI but not TaskModule
(URI handler needed for !Mail to pick up mailto: links).

Added display_height field to browser_data, analogous to display_width,
to cope with % sized objects by width and height (see how HRs are
handled in Redraw.c for an example of how it was always fairly easy
with width, but not height until this addition). Though you do have
to reload to get a new size; reformat isn't enough. Must see to this
some time...

Fixed bug where basic typefaces were claimed *before* the Choices file
had been read. For unusual Choices settings, this could create some
'interesting' problems now and again. This was part of narrower scope
work in the Choices code to allow font changing without leaking font
handles (now done; fm_shutdown only ditches fonts, it keeps internal
structures - must then call  fm_lose_fonts for all browsers to get the
bitfields up to date, then rewrite the typeface definitions and reclaim
basic fonts). Noticed that fm_claim_basic_typefaces would claim multiple
instances of the same font if there were several cases of the same font
mapped to different typeface styles - fixed.

Implemented PlugInControl settings, but not SupportObject (fully).

More reformatter code bugs fixed; this one regarding width of items. Any kerned string was overestimated (causing redraw bugs and caret position problems in forms, apart from other minor bits elsewhere) and the default size of a writable icon wasn't especially clever.

Crude Plug-In support; just about manages Java, but can't fetch on
behalf of Plug-In (for example). Had to change the default file access
URL construction to be 'file:/' instead of 'file://', or local file
fetches that reference Java applets won't work. This is in its very
early stages, and is being checked in mostly so that various Choices
issues can be worked on.

!Run[D] files updated for new fetchers and GopherFetcher; protocols list in Controls updated for Gopher. Debug builds now require 2760K rather than 2560K. Font$... variables set if not already, in anticipation of font

Choices work.

Additional bits in Choices section of Res file tidied and some name
changes (e.g. Netscape -> Navigator(TM)). Frames support option added
to Choices.

Grouped 'support_frames' under the Fetch Controls section and added
support_object in Global.h; appropriate entries placed in the Choices
files, and are read at startup. At present, though, only the frames
support flag is implemented.

For some reason, Menu was the button to use on history popups if you
wanted to show URLs instead of descriptions (or vice versa, depending
on Choices settings). Now, Select and Menu will show the Choices
defined setting, and Adjust will show the opposite.

History menus are built backwards, so local histories have the most
recently visited pages at the top. Global history has still no real
order to it, but this may be arranged later.

Customer name changed to Customer by request.

Customer browser now gets its own resources (SYSTEM=Customer), but
otherwise is unchanged, with the Ursula build now giving the
'spinning acorn' with a Bookworm-style toolbar. This is used for the
Desktop !Browse build.

!Sprites[22] files updated to include GIF, JPEG and PNG sprites;
!Run[D] files and !Boot files set appropriate File$Type_xxx variables.
Sprites in all sprites files have been checked for unnecessary palettes,
which have been removed where present.

Big steps forward in vertical white space handling as a result of improvements in HTMLLib in this area ( -> all versions now 1.22 beta-2).

As a result, the 'last_space' field in browser_data struct has been
removed. Note that this relies quite heavily on setting of the PCDATA
bit in the 'style' field of an HStream and the automatic collapsing
of (for example) multiple P tags inside HTMLLib.

Trace.c improved to recognise various bits in the 'style' field of an
HStream structure.

Phoenix defaults altered to a more 'standard' set of choices; Trinity
as the serif font, with a slightly larger default font size. This is
because there's a good chance it might get released to a wider audience
than Acorn internal (though the animation and icon bar sprites will
have to change before then...).

MiscDefs updated for new SWI numbers in HTTP module; !Run[D] files thus
updated to require HTTP 0.42 or later. At this point, all earlier
modules are not backwards compatible in terms of direct calls to the
HTTP module, though this only affects cookies_process_cookie at present.
At the same time, checks for System$Path, InetDBase$Path, and setting
of Inet$MimeMappings if not already defined have been added to the Run
files along with RMEnsures of Resolver and MimeMap.

Object and PlugIn c/h pairs created to handle OBJECT, EMBED and APPLET,
and the RISC OS Plug-In interface respectively. Not part of the build
process yet. Addition of 'odata' field in browser_data struct and
definition of chunk CK_OBJB for memory_set_chunk_size() are in support
of this.

Changed some error handling in Choices, a little bit of reformatting, removed unnecessary tempstring in Main, and played about with the choices Res file objects.
