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.

Significant reduction in number of times reformatter is called during
a table widthing session results in a dramatic speed increase for nested
tables (e.g. 64 deep with a paragraph of text in the deepest table takes
about two seconds to load with near-instantaneous subsequent reformats,
as opposed to taking optimistically 28 days for a 32 deep table!).
This code relies on a very big stack of assumptions...

Save as plain text implemented.

Choices, Messages and Res files brought up to date where necessary.
Version number taken to 1.28, 04-Dec-97 (so I don't forget later,
basically...).

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.

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.

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).

Added MimeMap module support. OBJECT routines now use this to determine if the item is an inline image, and if so pass it to the image routines.

At present, support relies on a (correct) content type.

Now working on source merged with Kevin Bracey's internationalisation support. UNIFONT is undefined in the Make File for now. All Res and

Choices files updated appropriately.

Having sorted out the old Choices and Messages to form Choices, Controls
and Messages, this build has had the same cleaning up done internally.
This includes greater consistency in naming schemes and the removal of
the inconsitent choices items - e.g. Choices file entries saying 'delay
images' and 'plain backgrounds' where internally all the flags say 'show
images' and 'show backgrounds'. ChoiceDefs.h and CtrlDefs.h added to
clarify the meaning of some fields, though usage of these is not 100%
in the source (there are cases where parameters are passed through to
functions as ints, and those functions still check these against hard
coded values rather than the #define stuff).

Fetcher status return bits (connected, sent request, etc.) now reflected
in status bar. Progress during fetchs to files are reported by %, where
the size of th...

Added 'save current location'. Res files updated appropriately. Version number taken to Beta-3; next will be 1.21, including K.Bracey's i18n code.

As warned in the last log, pretty much all event codes and component IDs have now changed along with many of the names, to provide a consistent name and numberspace for events and components. This also minimises number clashes (e.g. as was, the Save File origin when opened from a

Hotlist menu with an already-used component ID). To get full details on
this, please carefully read through TBEvents.h.

Res files, Sprites files and Messages files have been updated again both
due to the above, and routine additions (e.g. message support for a few
Hotlist bits and pieces). !Run[D] files updated for FTP 0.11 and
HTTP 0.36.

In the Makefile, the Customer objects list was missing Save - must have
moved something when I should've copied it, when adding in SaveFile or
SaveObject in all probability. Now fixed. Couple of other bits and bobs
fixed in the build environment (e.g. stuff saying !Argo instead of
!Customer). Oh, and I've altered the MakeFile copy options again to the
best compromise I can come up with. Newer is turned on for everything
except !Run[D] and !RunImage, since both of those change between debug
builds - otherwise if you'd built debug and non-debug versions, it was
not possible to switch between them - one version would have the newer
timestamp and thus never get overwritten.

The default hotlist has had a few items added - that'll be about the end
of it, I think; there's more than enough stuff in there now.

Saving of the hotlist from the document menu and of URI files,
directories and selections from the hotlist menu tree is now implemented
- this new save system rocks... Oh, and you can save all images and
backgrounds as sprites.

Saving of items with Shift+Click to other applications directly now
works, and is robust. Unique Scrap filenames are used, with data load
bounces (e.g. if some pra - er, person quits the app they're sending
to) working correctly - that is, give an error, keep the file, rename
it to something safe, and open the directory it lies in. As opposed
to normal app-to-app bounces, where the scrap file is deleted (see
PRM 3-254). This means you can now look at README files in FTP
sites, say, without using a disc intermediate. Or you can send pictures
straight to ChangeFSI, fetch HTML links into editors, and so-on, and
so-on - it's all very funky. Known problems include the ambiguous
'invalid component ID' instead of 'file open' for *normal* (straight to
disc) shift+click saves, and I think I'll introduce a unique name
guarantee of some sort to stop 'file open' in the first place. Odd
that the really tricky part (app-to-app) should be least likely to
suffer from this!

Only the Browse resources are currently valid.

Added Utils.Icons - has a few archives inside containing the resources
(well, some of them) used to build various UI sprites for various builds.
Archived because these are unlikely to change much, and putting them on
CVS was a move to, well, archive the stuff...

SaveDBox objects vanquished and requirements in !Run[D] files removed. The
data save code fits much more neatly in amongst the data load protocol
stuff now (with the slight exception of having to split the SaveObject
source into SaveObject and SaveFile - the former handles multiple persistent
dialogues for Shift+Click on links and the like, the latter handles 'one at
a time' transient dialogues for save source and similar). Export Link is now
supported, too, and writes a 'proper' version URI file. You'll find that
double-clicking on old URI files will work as the URI handler picks them up,
whilst new version ones don't; however, dragging onto the browser will only
work with new version files. Note that support for saving and loading URL
files (ANT suite stuff) is present too, so old URI files can be typed as URL
files if you want to keep them working without modification - the URI
handler itself will hopefully support the defined URI file format soon;
double-clicking on old URI files will stop working at that point. Note
there are *lots* of changes in every Res file to support all this. This may
all seem a bit pointless to some, but the changes do in fact make it very
easy to add new save dialogues all over the place. Certainly much easier
than with the previous system, anyway. In fact, post script, image
'save as sprite' took about half an hour, which I hope proves the worth
of the new system.

Merged in newer hotlist code with support for drag cancelling with Escape
(all relevant Res files appropriately updated) and cancelling scrolling
when you've reached the window scroll limit. Had to move some of the
Wimp message handling stuff to the central Protocols source, as clashes
were occuring, and also the hotlist routines were using independent saving
code - a lot of duplicated effort. This was fair enough as at the time the
Hotlist code was written, the Save code couldn't be used in the way it is
now.

New Save Source and Print buttons on the toolbar of some builds.

Phoenix Sprites file made more efficient - the Acorn base section has been
split from the animated upper region. Browse build has a new grey fade
sprite at the back, which is less grainy than the previous one and only
uses 16 colours (with a 16 greyscale palette).

Not really a bug, bug the routine to start an image fetch for INPUT
TYPE=IMAGE forms items only did so if the src field (or equivalent, for
this tag type) was non-NULL. In fact, you should always call image_new_image
and let that handle the rest, otherwise other sections of the code will fail
as they try to obtain an image number for a given HStream and get -1 back.
This problem only generally manifested itself when loading an HTML file to
the browser straight from an application, as many src fields become NULL
when the relativisation routines find nothing to relativise to...

Authentication got broken somewhere along the line - this has been fixed
(in HTMLLib and the browser).

Ctrl+Click on a cross referenced image updates *all* copies, not just the
one with the image data attached.

Next big step: Rip up TBEvents.h and rebuild that whole approach somewhat.
To all those working on the code, my apologies but this means all Res files
will receive a very large number of alterations and there will be extensive
code changes too (mostly naming convention stuff), in more or less all
source files. I am endeavouring to ensure that the new numberspace
convention does not clash with the work being done by Kevin on
internationalisation.
