GitLab

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.

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).

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...).

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.

Res files sorted out a bit, to add the Proxy option to the Choices dialogues
and fix the position of the menu popup in the Others pane.

Bogus comment in Global.h showed up when trying to build the Customer
variant (SINGLE_USER undefined); fixed.

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...

Sorted out Res files, including fixing position of 'bytes' label in one of the Choices dialogues (I'd missed it out of a selection when everything else got moved down a bit). Unfaded Enc_Chinese menu entries, made sure text labels were wide enough for system font, changed 'Apply' on Choices dialogue to 'Set', and added ^K to hotlist keyboard shortcut lists.

Print Setup (i.e. Print dialogue) buttons all set to 'local', so the
stupid Toolbox doesn't close the dialogue and lose the caret before I
can see if it was in there to start with...

256 colour hotlist sprites taken back to standard 16 colour versions,
since there's a significant speed penalty on slower machines. The
testbed browser still has the 256 colour versions so the designs aren't
completely lost.

Changed access settings to exported builds to wr/r - lr/r was really getting
on my nerves whenever I wanted to try something temporary out.

View source, save source and print handlers would all try to work if
there was no source to act on - despite the fact that toolbar buttons
would be greyed out form them. This is fixed.

The Navigate menu has components greyed to match the toolbar state,
when opened. It isn't kept up to date dynamically, though this shouldn't
really be a problem (reopen the submenu...). As part of this, finally
sorted out conditions for the Stop button to be greyed, or the
GoTo/Go/Stop tristate to be at 'Stop' versus 'GoTo'.

Deferred reformatting is now disabled for external image fetches.

Browser-local client pull flag removed; hitting the Stop button simply
cancels any null handlers working for it. That way, client pull switches
back on in passing at the next fetch (it was never really switched off).
So to stop client pull, hit the stop button at any point.

Done CELLPADDING attribute; cellpadding field in reformat_cell (Global.h)
is redundant since the table token is accessible from there, and so it has
been removed. CELLSPACING support also added.

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.

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.

Calling HtmlEndParse at the end of html_get_next_token and setting up->context to NULL was wrong; fetch_fetcher would end up recalling html_get_next_token later which would then call HtmlParse even though the document parse had just finished! The HtmlEndParse call has now been moved to fetch_stop.

Altered reformatter to claim fonts inside a browser, rather than
claiming them for nothing and losing them afterwards.

Got rid of TAG == TABLE and ISBODY tests, replacing with tagno == TAG_TABLE.
Removed all references to TD, TH, TR and TABLE in the style word.

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.

New save choices function with supporting code in Save.c; 'Save choices'
option in the Choices menu is now implemented.

Choices and Controls files are now loaded into malloc space (use chf and cof to address them). Previously only in Main.c, task_dir is now globally visible.

Choices updated to allow 16ths of a point in the font size specification
and the System font face has been removed - it isn't used. The use of
serif and sans serif fonts has been rationalised across builds (e.g. Desktop
builds use what they say, but the Customer build uses Homerton as the
default body (serif, so to speak) font as it matches the box's look and
feel better).

Font loading altered a bit to work properly! Font library defines some
standard startup fonts without using Choices, which Choices can then
override.

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 the object is known. Exceeding 100% drops back to a byte
counter, in case the estimated size was wrong. The progress counter
may be updated after specific delays, rather than 'as often as possible',
to reduce flicker (as requested by D.Brown some time ago).

I've done a small rewrite of the fetch prioritisation scheme in FetchPage.c;
how well this performs in general use across different processor speeds
remains to be tested, but certainly it has some advantages. For each small
fetch window before the rewrite, a 4cs tight loop was entered - this gave a
noticable and substantial drain to the Desktop performance if more than one
was opened. Now, several can be up at once with little hit. The actual file
fetch is on half the priority it was before, with all others taken back
just a bit - e.g. from 20cs per poll to 15cs per poll for flat out
reformatting. You don't seem to lose much time on the format in practice,
and the Desktop feels quite a bit lighter at the same time. There's the
potential for smoother frameset loading in this scheme, too.

When Shift+Clicking on a link meant you still fetched inside the main
browser window, several fetches could occur in a frameset - one per frame.
However, now that you can only do this by clicking on a link that leads to
non-displayable data - or by turning off the small fetch windows by
setting UseSmall to 'no' in Choices - a bug where fetchpage_preprocessed
would stop such fetches as new ones were started was revealed.
The API to frames_abort_fetching has now been extended to include a
'stop file spooling too' flag, allowing a fix to be made by having
fetchpage_preprocess's calls not set this (and it doesn't check the
savelink flag is unset before proceeding, since frames_abort_fetching
does that implicitly now).

Had left the RAM transfer buffer at 16 bytes (from testing) accidentally...
Oops. Upped it to 4K. In addition, when loading data by RAM transfer,
the browser didn't notice if a RAMFetch bounced during the transfer. It
would be treated as a 'first' RAMFetch bounce, basically, and try to go to
file transfer - oops. Fixed.

Encoding support added: if UNIFONT is defined then the browser will attempt to use the system font to render Unicode characters (new

International module required). If not defined, the browser will just
handle Acorn Latin-1 characters, but HTMLLib will convert other encodings
into Latin-1. Must keep the UNIFONT define in sync with HTMLLib (if
defined HTMLLib outputs UTF-8, otherwise Acorn Latin-1).

Still needed:

Reverse encoding (converting form input etc back into the server's
character set).
Reparse when encoding changes.
Setting of charset from an attribute on the <A> tag.

Image deletion routines rewritten; nasty animated GIF bug now gone
(it kept trying to update the cross-referenced image in the browser that
no longer existed, and I've no idea how animated GIFs ever managed to *not*
blow up if a cross referencing browser was shut down; and I've tested
this...). There are now as many image structures as there are total images
in the visible browsers, and no more; cross referenced images in the
to-be-deleted browser have their ownership moved to the cross
referencer before the cross referencee is wiped, with any required fetches
being transferred with them.

Reformatter sped up a bit by getting rid of strlen on the main text field
of tokens in all places bar one, where it is called extremely rarely. This
means direct app-to-app transfer of, say, a 359K text file to the browser
won't run like a drain as it tries to do strlen on a 359K string over and
over again! Most of the time the performance benefits won't really be
noticable, but on the above text file, formatting time went down from
290 seconds before the change to just under 7 seconds, a 41 fold speed
increase or thereabouts (SA110 228MHz).

MakeFile changed to force function name compilation on for debug builds
(-fn in the DD...FLAGS); useful for certain functions such as
register_null_handler, which can now output the name of the function
being registered.

...Which helped show up some nasties in the animation handler and animation
drift handler registration/deregistration process, which have been fixed
(callers of fetchpage_release_nulls were unaware that the drift handler
could be installed, and fragments of old code checking choices.anim_drift
had a value other than 1 or 0 were still hanging around - bit tricky for
a single bit item).

Added support for VALIGN in table cells. Spotted a bug or two in the
'what token is the pointer over' routines as a result, and fixed them - the
worst was in browser_line_at_y, which checked the y coordinate was below
the given one [the mouse], but didn't check the line height to see if the
given y coordinate was *within* the line, rather than just above it. Never
used to matter pre-tables, but a definite concern once multiple line
arrays can exist on one page.

Got the deferred reformatter working properly. It doesn't do that 'OK, the page is fetched and reformatted, but just to annoy you, I'm going to wait 5 seconds and then suddenly reformat the whole thing again' trick anymore. The fetcher was calling the reformatter in a delayed form even when the reformatter was already running, so it would carry on past the reformat point or from below what had become and invalidated line, and some time later, get back to the delayed reformat. Now, reformatting is only delayed by the fetcher when the reformatter is not running. In practice this means body text reformats as it fetches, but large tables will show delayed reformatting - which was exactly the intended behaviour of the feature when it was originally thought of.

fetch_token_data_address removed; it was only needed in two places,
both of which already knew when to read tp->text and when to ignore
it. Its functionality is duplicated in an 'if' involving reformat_istext,
anyway.

!Run[D] files taken back to requiring HTTP 0.33, since 0.36 introduces
many weird and wonderful problems.

Typo in Messages files, 'All current images (sic.) fetches finished' -
'images' is now 'image'.

Shift+Click saving - you could save to an application. No problem. But
the equivalent (just clicking on a link that led to an unknown datatype
and getting the save dialogue that way) didn't work. It does now.
Another problem was saving to an application that didn't support the
datatype - oops, the dialogue would close but the fetch would sit there
waiting to be told where to save. It doesn't close now (as expected).

NB, doing several simultaneous fetches to a text editor may have problems
as the editors are too clever for their own good. Despite receiving
DataLoad messages for <Wimp$Scrap> for files of different types, sizes
and datestamps, the editors can decide it's still the same file and:

Zap      - Hats off, it gets it right, almost. You do get warned 'Multiple
           copies - one on disc is newer' as everything after the first
           text loads, but they do load, and in separate windows.
StrongED - Does not load the subsequent files, so the browser gives 'Data
           transfer failed' errors and opens up Scrap. Turning off 'Don't
           load same file twice' fixes it - each file is loaded in a new
           window with no warnings. At least in the first case, you don't
           lose data, since the files are kept in Scrap.
Edit     - Each time it loads the file, it *replaces* the other one in
           memory, using the same window for each. This is the worst
           behaviour as it isn't configurable (well, I don't know of a way
           to change it...) and results in data loss as successive texts
           get trounced by the new data.

I can't see how I can fix this in the browser as it's basically silly
behaviour on behalf of the editors. Other applications which don't try
to work out if it's a new file or not are fine!

When conducting image fetches, proxying is allowed unless reloading.
When conducting page fetches, proxying was never allowed - so web cache
stuff would have been, er, interesting. It now sets X-NoProxy: in the
request header when reloading, but otherwise this is not included.

AnimSpeed is, at last, independent of browser poll speed. They used to
be tied together. Guess how the animation code used to work ;-)

'Can't handle this datatype' - deprecated now that save dialogues can be
popped up. The 'can't save objects in full screen mode' error would never
be shown due to a bug, anyway; this now replaces 'can't handle', which
has been removed from all Messages files.

RefoWait, RefoHang and RefoTime moved from Controls back to Choices.

Trying to get rid of strlen in the reformatter - it can get very slow
(e.g. strlen of 8K chunks of text, or if a 330K text file is transferred
from a text editor straight to the browser, strlen of a 330K string...).
There will be unfinished bits of code in the reformatter that may seem
unnecessary - they've just not been plugged in yet (since they don't
actually work). Don't remove them!

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.

This version is being checked in because the Hotlist manager in the test build provokes a Wimp bug. All the variant resource files are out of sync and there are several outstanding bugs in the main code, so I'd personally avoid this build like the plague unless you're mad enough to want to examine the Wimp problem ;-)

Created Protocols source file and moved a lot of message handling from handle_messages - the latter now serves as a high level distributor to lower level functions in Protocols. Incidentally, URL files (as used by the ANT suite) can be loaded by dragging to the browser in the same way as URI files - Not A Lot Of People Know That, etc.

Merged new hotlist display type Res file to existing resources, added
support for DataSave message so items can be dragged from the hotlist
to a specific window (RAM transfer for URI and URL files; ScrapFile for
HTML and Text but deleted afterwards and there are appropriate guards
to stop Reload just saying 'not found'; images run through ScrapFile and
there is no choice but to leave them there and do a conventional fetch).

All !RunD files now give a WimpSlot of 2304K. Some small changes to
the Argo and Ursula build Res files to make the menu trees more sensible.
Controls files now take 'file:/' instead of 'file://' in Protocols
section. Definitions at top of URLutils.c *not* altered, as then you
end up with invalid URLs - so it will accept 'file:/', but always generate
'file://'. This is because some browsers exports 'file:/'. Sigh.

make_no_[..._]memory_error functions now return a _kernel_oserror * rather
than void. It's always &erb returned, but it enables users to use a more
elegant 'return make_no_memory_error(1);', say, rather than something
like 'make_no_memory_error(1); return &erb;'. I obviously should've written
it like that at the outset, but never mind. All callers have been
appropriately updated.

The urlutils_leafname_from_url function now replaces illegal characters
(A7000 Welcome Guide p54...) in the leaf with legal alternatives.

Internal URL scheme is now a bit cleaner, with everything properly defined
in URLutils.h. All references to http:, file: and ftp:, with or without
a following '//' use the definitions in here now.

More tidying and some reorganising of Hotlist source. Auto-open delay is
now a Choices item. Some dependencies on statics removed (e.g. the
counting functions don't accumulate into the global item_number now).
The redraw functions used Wimp_TextOp - oops, so this has been amended
to use whatever is supported on your Wimp. This is now in a new function
(utils_text_width()), which the History menu routines also use (there was
a bug in the width routine there anyway, which is therefore fixed in
passing). Several other routines used Wimp_TextOp directly too, and
they have been altered to use the new function as well.

In hotlist code, one of the larger changes is in the API to hotlist_draw_r()
(formerly _hotlist_draw()) which now takes item widths and heights as
parameters - discovering these is quite slow, so doing it every time the
function calls itself recursively is a little less efficient than
passing the values in from elsewhere. Note that underscore prefixed
functions are being slowly renamed to _r suffixed functions, to match
the convention established by Tony Cheal with is table routines. This
makes it much more obvious when something is recursive, as the same
naming convention is used in every browser source file.

Finally, note that I intend to ditch SaveDBox and use an alternate window
with manual control of the messaging in Protocols.c. This will allow
various improvements which at present the SaveDBox operational methods
preclude. I'm going to have to do at least an alternate Window object for
the SaveDBox module to use soon in any case. Getting rid of SaveDBox will
help reduce, if only slightly, demands on the RMA.

Open URL implementation more or less complete, though may undergo UI
revision at a later date to allow named frames to be targetted. Hope to use
the ideas in this code as the foundation for other general dialogues.

In token stream dump for TRACE builds, table head items were not indented
as far as they should have been - this is fixed; and manual toolbar redraw
routines have been removed. They never worked, were commented out, and
would never be used in that form anyway.

DragBox source added, but it isn't at all complete and won't work - this is
an 'in spare time' thing. We need custom drag boxes constrained to windows
for the hotlist, and unconstrained for frame border resizing... Hey ho.

Ancestor window extents match visible areas if there are frames (no more
scrolling framesets...!). Frame resizing works whilst new documents fetch
without pulling the extent down now. However, frame horizontal extents
never shrink until a reload which is nasty, and this is all due for a
rewrite. Frames border redrawing routine moved out of Redraw.c and into
Frames.c. Bug regarding the mouse rectangle and frame border widths
(rectangle was too large, so you could squash the edges) for edge-drag
frame resizes fixed.

Window width change reformat tolerance fixed; you could creep the window
width down or up forever without any reformat, and centred objects would
move but not be redrawn (thereby giving rise to subsequent redraw errors).

Filetype on objects saved through Shift+Click correct. Save Source dialogue
recognises if that source is plain text, rather than assuming HTML. A
browser that fetches a file remembers the old store size it had before the
save, so even though the data is now ditched, it reports the same amount of
data fetched afterwards (looked awful when this could, for example,
suddenly say '0' after a file save). Progress indicator is now fully aware
of one or many file saves inside a frameset and reports the number of
saves, a colon, and the cumulative saved data count, instead of reporting
the sum total of fetched data in all frames, including non-file save stuff
(note that for just 1 save, '1:' is not shown as a special case for the
most common condition). A bug related to this, where you could in fact only
do one fetch per frame*set*, has been corrected (only one fetch allowed per
frame still, this is unlikely to ever change).

Hotlist support added (D.Brown's source), with various bits of integration
and modification still in progress there. Note additions to the Messages
files. On the subject of Messages, the whole mucky business about what
goes in Messages or Choices (and a few bugs where lookup_choice was used
instead of lookup_token or vice versa) has been sorted out. Messages
contains, more or less, just that. Choices contains user configurable
stuff which generally can't mess things up too badly. A new file, Controls,
is a Messages file holding the non-user configurable choices, which can
generally make things go badly wrong if misused. A lot of these are tied
to the Res file. StrongED users can get these to automatically fold out
the various sections (EMail me for details). Sorry, but at the time of
writing, Zap doesn't do folding... =8*P

Two bugs with images. Asking for images to be shown in browser B when
browser A uses the same ones and was loaded first didn't work correctly,
and now does (a bit weird - browser A does the fetch and browser B does the
display...). Second one occurred when the background image was also used on
the page as a foreground image. This has been fixed by flagging background
images in the image_info structure, and checking this before cross
referencing. This bit also allowed the image_restart_fetches API to be
extended, so that just background or foreground images may be fetched if
they weren't already and the user asked the browser to show them. Before,
the whole lot had to be fetched together (so turning on 'display
backgrounds' will now kick off an image fetch if required, you don't
need to reload the page anymore).

Makefile copy options tweaked to be 'newer' (so if you're testing with some
temporary Choices file or something, it won't write over it at the end of
every export), and REMOTE_HOTLIST flag added for Customer builds - means
the Hotlist.c functions aren't needed; the old, hotlist-by-file method is
used. Added support for Customer build (see later), though there were very
few additions needed in practice.

Table printing fixed - in many ways it wasn't broken, it was image printing
causing the oddities ever since the global image pool was introduced (this
is, again, fixed). The 'reformat to fit page' option didn't work as coded
any more; tables store cell addresses in the HStreams, so you can't then do
a background reformat in a different browser. Hence, it now has to reformat
to the page width, print, then put the page back again, all in the actual
displayed browser. This doesn't feel as slow in use as it perhaps should,
considering what is going on... Note that a line of a defined fraction (see
Print.h) of page height will now split over page boundaries, so tall images
or tall tables don't cause problems now (aside from the obvious problem of
having the line split over a page at all!). There was a bug in the routine
to print from a given start point until 'n' pages had been filled, in that
it always filled 'n + 1' - now fixed. Finally, as part of the printing
tweaks, a new dialogue exists - PrintStyle - with a similarly named source
file added to deal with it.

Global history auto save / load done, but only to the Choices file path -
the whole browser is still strictly single user at present, with all the
extra work for a multiuser Customer environment yet to be done. This has
shown up a global history corruption problem which I haven't fixed yet.

Rationalising TBEvents.h - things are migrating out of it, and into more
appropriate sources (e.g. definitions relating to the Open URL dialogue are
going into OpenURL.h, etc.). Event codes were at one stage deliberately
diverged in numberspace from the component IDs of typical gadgets raising
the events, to avoid anyone getting confused and thinking the IDs and event
codes must match. However, this is in fact unlikely and it is much easier
to remember the fewer numbers that result from tying the two together where
possible. This has resulted in changes to event codes raised in the
following objects of all Res files: Authorise, Find, OpenURL, and
PrintStyle.

And finally - !Run[D] files for all variants updated to require the latest
toolbox and fetcher modules. All Res files updated for hotlists etc. and
sprites files updated appropriately. All Messages, Choices and Controls
files brought in sync., and an Customer build has been added (based on the
Desktop build binary with different resources).

That's all for now...

(adding up to a greater whole), which include removal of the dastardly
'invalid image number' errors that trace builds would raise from time to
time. Frame highlights are now better controlled (releaseably so).
Generally, this build represents the first genuinely promising version
of the browser for quite some time, despite the known library problems
with comment handling etc.

Fixed problems with unsourced images in tables and a couple of other bugs here and there - nothing earth shattering... Just wanted to keep the CVS source up to date.

Altered dialler status reporting to be more efficient (only installs the null handler when it needs the online time)

Added various TaskObey files to make different browser variants (the Makefile has been updated to support this). At present, TARGET must be set for the

Make file to work (some oddity in AMU causing problems here). Added
Multiuser.h to cope with a non-SINGLE_USER build for Customer.
