There are a few known significant problems with this code but it's being checked in so the Choices can be worked on. Note that Res files etc. are not up to date across all builds. Progress is as follows... Bug report prompted me to do this - now ignore <p> tags straight after <li> tags, so '<ul><li><p>Some text' works as the author (or automatic generator, more commonly) intended. A <p> tag before a table will be acted upon now (it was ignored before). Something like <li><p><table...> will give a line break and paragraph space after the <li> despite the changes mentioned above, as in other browsers. Both browsers differ from Navigator, where the table appears alongside the <li> tag. Multiple BR tags work as in MSIE / Navigator (they don't collapse to zero height anymore). For the above, line height (and so, <br><br> or <p> spacing) is now calculated inside reformat_text_line_height, and is used with either a token to get the text height at a given size (e.g. for general line spacing or multiple BR tags) or NULL for normal size text (e.g. for P spacing, though this value is in practice later scaled by 7/8ths in reformat_check_height). Note this behaviour is exhibited by MSIE 4; v3 gave two BRs the same spacing as one P (i.e. not font size dependent). Save dialogues can have an option button or couple of radios to switch between various formats (e.g. URI or URL, sprite or original format). See 'Docs.Notes' for more. The back-end to this is now implemented (i.e. at the moment, save as URI or URL, save as original image format). Note that when saving background images, a leafname based on the original fetch URL is now offered rather than a generic 'Background'. Internal URL scheme changed to be all lower case, so relativisation through URL_Fetcher still makes sense... :-/ Holding down 'shift' when clicking on stop reverses the interpretation of the Controls file 'StopWebServe' entry. Fixed row / column count for exporting tables as text; fixed a few bits and pieces of internal URL scheme stuff which got broken when HTMLLib started using URL_Fetcher's relativisation.

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.

Stopped UNIFONT forcing system font use and added calls to Font_WideFormat. Made sure the system font option is read before fm_init is called! User agent string now set if Netscape faking is disabled (format used is "Acorn Browse/1.26 (RISC OS 3.71)".

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.

Updated Res files in appropriate builds to hold various (similar) Choices designs. Choices related menus were flagged as Shared, but none of the dialogues (including ColourDBox) were - potential future problems, though shouldn't cause any leaks at present. This has been sorted out anyway. Encoding function encoding_init no longer returns an error from toolbox_create_object, so the Encoding menu and all those attached to it do not have to be present (e.g. the Customer build). SUB, SUP, STRIKE and U supported. U underlines the baseline of the body text font, whilst STRIKE will go through roughly the middle of the lower case chars even if the font is SUP or SUB. Note that Navigator appears to shift the underline point for SUB and SUP; it may be necessary to copy this behaviour, but testing on real sites must proceed before that. There could also be a problem with the automatic lowering of font size, which Navigator doesn't do, so any FONT SIZE = -n commands coul...

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.

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!

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.
