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.

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...
