GitLab

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

Version 2.11. Tagged as 'Browse-2_11'

Completion of v2.11 check-in of Phoenix (note that the application gets its reported version number and date from Messages, not the

  VersionNum file, which updates independently).
Detail:
  Various resources updated. New About stuff included. Modification to
  Hotlist.c to ask DragAnObject to *really* call it in USR mode; requires
  DragAnObject 0.09. New "RMTry" utility in Phoenix to help make finding
  up to date modules more friendly - works well in itself but slows down
  the loading time quite a bit; would be nice to find a better solution.
  This will do in the short term, as it's a definite improvement over
  the way the !Run files used to work.
Admin:
  Use of DragAnObject 0.09 fixes aborts when trying to drag items around
  in the hotlist.

Version 2.10. Tagged as 'Browse-2_10'

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  will definitely be out of date for other versions.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

Version 2.09. Tagged as 'Browse-2_09'

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

Version 2.08. Not tagged

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

getting the ROM build working, and internationalisation issues).

Version 2.08. Not tagged

Authorisation works for image fetches. Previously authorise_authorise assumed any check was for a browser page. Now looks at the dialogue box client handle, which is 0 for the page or a fetch handle for an image.

The urlstat structure this relates to now has lasttoken filled in for
the token the image represents, which gives the URL to which the
user name and password relate.

Further printing tweaks. Font colours inside anchors now work (must be built with the 02-Mar-2000 HTMLLib or later). Event log won't show guts of internal URLs for just-born browser windows if displaying the list by URL. Empty Location headers don't redirect down zero page and give a nasty internal error; raise "no fetcher service found" instead.

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

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

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

Only the Phoenix resources are up to date currently.

Printing engine will attempt not to seperate headings from non-heading
items. If the current line is a heading and the next is not, and falls
off the bottom edge of the paper, then both lines will be carried over
to the next page. Similarly for DT and DD items. Maximum line height to
push rather than split is now altered to 2/3 of page height (was 1/2).

JavaScript fix; a URL's "protocol" value should include a ':' at the end.

Removed svcprint fron objects list of non-debug files and put svcprint.c back to its conditional compilation behaviour.

Note that as usual, this check-in gives an incomplete set of resources.
Only the Phoenix build will be reasonably up to date.

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

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

StripExtensions option controls auto stripping of filename extensions.

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

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

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

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

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

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

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

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

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

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

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

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

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

Corrected the Font Manager bug that never was - adjustment calculations for line height in preformatted text were bogus. Fixed also daft use of '&&' instead of '&' in trace build conditional debug output for image_purge_deleted_entries.

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

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

Default parameter HRs now plot properly in rectangular pixel modes.

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

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

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

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

Lazy clearing of backgrounds - pages with the same background image or
colour won't be cleared to grey when going from one to the next anymore.

BODY element onLoad script attribute implemented properly (beyond the
Customer hackery).

Images use independent flex blocks for URL and transient fetch data;
greatly improved data throughput in image system as a result. Image
renumbering implemented - speeds up closing of pages / frames with
many images. Image xref is still rather slow though and images with
a 0 width or height specified in the HTML still cause an incorrectly
formatted page to appear.

Have, I think, fixed the "stops anti-aliasing" bug. Noticed that some
background images are not being processed as Fast (e.g. at the
Fibblesnork Lego Guide) - that old problem has reappeared, then.

Background images would cross reference when two pages had the same
background colour set in <body> elements but one was configured to use
document colours and one wasn't (so xref should not occur). Code was
looking at b->background_colour; corrected to call redraw_backcol(b).

Titles were added to the history according to the fetch URL not the
display URL, though the former is more likely to be in the history due
to the code execution order in the fetcher; changed to see whether this
improves upon the rather hit and miss addition of titles.

The 'about:' page now gets entered into the history (makes for much more
sensible behaviour if it is configured as a Home page, for example).

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

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

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

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

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

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

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

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

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

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

Here's the change list:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

MIDI themes is unreachable, Hensa has been restructured.

For table cells where the line or chunk data totals less than Flex_256_Point
bytes (see top of Memory.c, current value is 8192) there would be an over-
allocation of 1 byte per cell due to a (now fixed) bug in the granular
allocator. This would translate into 4 bytes wastage of course, and may
represent a small speed penalty depending on how flex works out block
word alignment.

Several entries in the Choices file were missing from save_save_choices in
its new form (see last check-in). Added back in. Ursula and Phoenix Res
files contained an incorrect component ID in pane 3 that was stopping the
'no scroll bars' option in pane 7 working correctly (duplicate component
ID). Res files corrected; TRACE builds will now spot such errors and give
a warning when they occur (in choices_find_component).

Table widthing code fixes:

 * Very wide table cell specifiers (e.g. TD WIDTH="2000") were ignored,
   but this isn't what Navigator / MSIE 4 do. This code was present
   because of other bugs in the widther, long since fixed. The code has
   been commented out - if the problem reappears the use of the code can
   be re-investigated, but as far as I can tell it isn't needed.

 * If two pixel specified cells appear one above the other, the first
   would always have been taken for use in the final width calculation
   even if it specified a smaller width than the second. The check was
   made to ensure that pixel specifiers were chosen in preference to
   other cells, which is OK, but it didn't notice if the current cell
   was also a pixel specifier! Fixed; you now get the widest.

 * The TRACE build 'Colspan cell xxx would have been width yyy, below
   minimum width of zzz' error should no longer happen. In a manner similar
   to the bug mentioned above, two cells above each other spanning the
   same columns with the lower cell narrower than the upper would end up
   with the narrower width. The code that trapped and corrected the error
   was not compiled out of release builds, even though the error message
   generation was, because the rendering would fail otherwise. The widther
   has now been fixed not to make this mistake and the final check is now
   strictly TRACE build only, thereby speeding up table widthing for
   non-TRACE builds.

 * Another use of MSIE4StyleTables option, for cellspacing; it's based
   on the actual used cells, rather than the maximum cell width caused
   by COLSPAN etc. So if you've a cell with a big COLSPAN but as a
   heading but the rest of the table only uses, say, 4 columns, you won't
   get a gap to the right which adds up to the spacing for all of the
   cells that the COLSPAN attribute in the heading implied. The option
   was actually intended as 'bad things when switched on', and though in
   this case it makes for a better rendering, it does hide an error in
   the HTML. Note Navigator 4 acts as Browse with MSIE4StyleTables off
   in this particular case. Oh, it works in both ways of course, so
   the table height routine had to be updated too. A new function,
   tables_find_actual_size, exists to support the feature in general.

Messages files updated to v2.05 (21-Apr-98). Help menu items renamed a
bit in Ursula, Phoenix and Customer Res files, but entries still point
to the same URLs. Phoenix button bar markers have been brought closer
together to stop them being visible when only the URL bar is meant to
be present.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

One day, probably far into the future, I'll actually remember to 'cvs add' new source files before checking everything in.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Added a simple 'Find' facility.

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

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

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

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

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

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

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

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

The '3F6C0' abort fixed; reformat_left_margin didn't cope with a NULL cell pointer. This only happened if the image library tried to deal with an image in a table cell which wasn't properly dealt with by the table systems yet, for whatever reason. Rare, but persistent once it started happening because it depended on the value of the FIQ vector!

Put function header comments in SaveFile.c, at last.

Messages files now read version 2.01, 23 Feb 1998.

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

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

TIFFs do not get loaded by double-click now.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Machine hung during last check-in; trying again... Apologies for sending out such a huge log message *twice*.

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!).

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
