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, ...

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

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; how...

File fetches now set DEADDEAD during the fetch, Data if it is aborted, or an appropriate filetype when finished. If the fetcher routines return a zero or data filetype, the browser looks at a set of hard coded filename extensions to try and determine if there's a better filetype to use

(urlutils_filetype_from_url) - since this is a centralised routine it can
use a Mime mapping system (or be removed entirely) as and when one becomes
available.

You can now drag URI / URL files to the Hotlist window to add them to the
list. They are added roughly where dragged to. (NB, note that I renamed
the function to return the window ID - just being picky; it matches other
similar functions now). Oh, and hotlist_add_position actually works now ;-)

The global history will save when titles are added, as well as when a URL
is added. Before, a browser crash could mean a title got dropped out
of the history file even if SaveHistory was set to 'always'.

SaveObject sources have been added but nothing references them or links
them in yet - they're not finished. Mostly checking this one in because
of the hotlist changes.

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 *no...
