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.

CVS carried on anyway. It seems not all files that had changed locally
were checked in just from the srcnotify messages - so, I'm trying again...

Note that the 'Docs' documentation (possibly contrary to previous log messages) still hasn't been updated with the new SaveFile stuff, and function header comments have yet to be written for

SaveFile.c.

Fixed urlutils_pathname_to_url - OS_GSTrans doesn't like the same
input buffer as output buffer (fairly obvious, but I was living in
the hope of not having to duplicate the input path string).

Image history will not cache scrap file images anymore. Browser's
image handling library won't cross reference them either.

When dragging a single item from the hotlist to a Filer window, the
code now checks Ctrl - if held down, a URL file is written, else a
URI file. The state of any option buttons or radios in the last
Save File dialogue that was opened is no longer relevant...!

history_save_as_html could write out broken files when titles
for items in the History were not present. Fixed.

Hourglass switched on for hotlist and history saving as HTML;
hotlist_save_entries no longer closes the output file on error
(it should be done by the caller, since the caller is responsible
for opening the file and passing the FILE * pointer to
hotlist_save_entries).

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.

All hotlist_find_match calls wrapped in '#ifndef REMOTE_HOTLIST' compile time option, for some builds.

Cross referencing of images when the background colour is different - should
not do it for backgrounds, for e.g. alpha transparent PNGs would then fail.
This was implemented, but it turns out it affects *all* cross referencing!
Fixed for just background images.

As described in Docs.TagNames, the tag name "ahodgkin_127beta2" associated
with this checkin applies to everything *except* Choices.c. v1.27 beta 2
was build with the Choices file tagged "ahodgkin_127beta". The confusion
arises because Choices.c got independently updated and checked back in
before I checked in the v1.27 beta 2 changes myself.

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.
