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worked at the time (but will probably be out of date now) and included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).

Browsers with use default colours set only get redrawn by choices when the default colours have actually been changed.

There are a few known significant problems with this code but it's being checked in so the Choices can be worked on. Note that Res files etc. are not up to date across all builds. Progress is as follows...

Bug report prompted me to do this - now ignore <p> tags straight after
<li> tags, so '<ul><li><p>Some text' works as the author (or automatic
generator, more commonly) intended.

A <p> tag before a table will be acted upon now (it was ignored before).
Something like <li><p><table...> will give a line break and paragraph
space after the <li> despite the changes mentioned above, as in other browsers.
Both browsers differ from Navigator, where the table appears alongside
the <li> tag.

Multiple BR tags work as in MSIE / Navigator (they don't collapse to
zero height anymore).

For the above, line height (and so, <br><br> or <p> spacing) is now
calculated inside reformat_text_line_height, and is used with either
a token to get the text height at a given size (e.g. for general line
spacing or multiple BR tags) or NULL for normal size text (e.g. for
P spacing, though this value is in practice later scaled by 7/8ths in
reformat_check_height). Note this behaviour is exhibited by MSIE 4;
v3 gave two BRs the same spacing as one P (i.e. not font size
dependent).

Save dialogues can have an option button or couple of radios to
switch between various formats (e.g. URI or URL, sprite or original
format). See 'Docs.Notes' for more. The back-end to this is now
implemented (i.e. at the moment, save as URI or URL, save as original
image format). Note that when saving background images, a leafname
based on the original fetch URL is now offered rather than a generic
'Background'.

Internal URL scheme changed to be all lower case, so relativisation
through URL_Fetcher still makes sense... :-/

Holding down 'shift' when clicking on stop reverses the interpretation
of the Controls file 'StopWebServe' entry.

Fixed row / column count for exporting tables as text; fixed a few
bits and pieces of internal URL scheme stuff which got broken when
HTMLLib started using URL_Fetcher's relativisation.

i)  There can be two sets of gadgets, one set for page history and another set
    for image history.

ii) There can be one set of gadgets for both settings and two radio buttons to
    select between them.

Only one of these may be present at the same time.  Currently the radio button
version is the one that is in place.  To change to the other version delete the
radio buttons and copy the gadgets from the ChoicesTMP window into the
appropriate window.

Choices dialogue only gets created the first time it is opened (ie. it is not deleted every time it is closed anymore).  Can be controlled by a #define

More tidying.  Made choices_seconds_to_typed_time a LOT smaller.  Made choices_return_appropriate_timetype do what it says it does (thankfully not a problem for the bete released version).

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)".

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).

Minimal support for font choices added, fixed problem with colour changing with browsers with no background colour specified.  Options for Objects implemented.

Stopped various displays being redrawn unnecessarily when cancel is pressed in main choices dialogue.

Choices now allows gadgets to be in any subwindow with some limitations which are addressed in the header file.  Also there is no longer a concept of named subwindows.

Updated Res files in appropriate builds to hold various (similar) Choices
designs.

Choices related menus were flagged as Shared, but none of the dialogues
(including ColourDBox) were - potential future problems, though shouldn't
cause any leaks at present. This has been sorted out anyway.

Encoding function encoding_init no longer returns an error from
toolbox_create_object, so the Encoding menu and all those attached
to it do not have to be present (e.g. the Customer build).

SUB, SUP, STRIKE and U supported. U underlines the baseline of the body text
font, whilst STRIKE will go through roughly the middle of the lower case
chars even if the font is SUP or SUB. Note that Navigator appears to shift
the underline point for SUB and SUP; it may be necessary to copy this
behaviour, but testing on real sites must proceed before that. There could
also be a problem with the automatic lowering of font size, which Navigator
doesn't do, so any FONT SIZE = -n commands could make it too small. Again,
this needs testing on real sites.

'http://' is added to URLs with no protocol specified, unless they start with
'ftp.', in which case the new behaviour is to add 'ftp://'.

Choices code altered to do less error checking on components! They should be
able to be missing without raising errors. Referencing of the subwindow
array changed from *(subwindows + number) to subwindows[number].

Made trace_tag_name code look pretty...

reformat_useless_token now checks tagno is non-zero.

User Agent string setting now done through URL_GetURL, on a per-session
basis.

Ellipsis character removed from all Messages files, replaced with '...'.
There's little difference between the two in an outline font, and in System
font the latter looks much better. Smart quotes left in, as they look
better in all cases.

Didn't redraw browsers which would be immediately affected by a change to the Choices when 'Set' was used. Appropriate redraw calls added. Reversed decision to toe in the pane window by 8 OS units relative to the placeholder icon sides.

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.

Added run time RMEnsuring type behaviour for ColourDbox to save RMA space on start up of the browser.

Also added additional deregistering of events which I forgot to do last time :(
