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.

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.

StrongHelp generator on it. Revealed a spurious toolbox_hide_object call that would always fault and never do anything, and a few heinous uses of show_error which have all been removed. When dragging hotlist items, directories will now be highlighted whenever the item would be added to them, rather than just over the sprite. In practice this only changes if the item is open and has contents... Drag box selections had broken in the hotlist; fixed (uninitialised variable in hotlist_select_box). Adjust-drags now close the window on completion. Minor problem with Shift+Drag (copy) reversing order of items sorted out. Added hotlist_add_html_file and implemented loading of HTML. DO NOT add broken HTML files, this has not been coded for and URLs of the form http:///this/that (no host name) will hang the machine (bug in the cookie code of the HTTP module up to at least version 0.39). Made SELECT list items only as wide as the widest entry actually appears (using fm_get_string_width), rather than as wide as the widest character BBox in the font multiplied by the string length of the longest entry. Updated !Run[D] files to require HTTP 0.39, FTP 0.12 and File 0.23.

Now working on source merged with Kevin Bracey's internationalisation support. UNIFONT is undefined in the Make File for now. All Res and Choices files updated appropriately. Having sorted out the old Choices and Messages to form Choices, Controls and Messages, this build has had the same cleaning up done internally. This includes greater consistency in naming schemes and the removal of the inconsitent choices items - e.g. Choices file entries saying 'delay images' and 'plain backgrounds' where internally all the flags say 'show images' and 'show backgrounds'. ChoiceDefs.h and CtrlDefs.h added to clarify the meaning of some fields, though usage of these is not 100% in the source (there are cases where parameters are passed through to functions as ints, and those functions still check these against hard coded values rather than the #define stuff). Fetcher status return bits (connected, sent request, etc.) now reflected in status bar. Progress during fetchs to files are reported by %, where the size of the object is known. Exceeding 100% drops back to a byte counter, in case the estimated size was wrong. The progress counter may be updated after specific delays, rather than 'as often as possible', to reduce flicker (as requested by D.Brown some time ago). I've done a small rewrite of the fetch prioritisation scheme in FetchPage.c; how well this performs in general use across different processor speeds remains to be tested, but certainly it has some advantages. For each small fetch window before the rewrite, a 4cs tight loop was entered - this gave a noticable and substantial drain to the Desktop performance if more than one was opened. Now, several can be up at once with little hit. The actual file fetch is on half the priority it was before, with all others taken back just a bit - e.g. from 20cs per poll to 15cs per poll for flat out reformatting. You don't seem to lose much time on the format in practice, and the Desktop feels quite a bit lighter at the same time. There's the potential for smoother frameset loading in this scheme, too. When Shift+Clicking on a link meant you still fetched inside the main browser window, several fetches could occur in a frameset - one per frame. However, now that you can only do this by clicking on a link that leads to non-displayable data - or by turning off the small fetch windows by setting UseSmall to 'no' in Choices - a bug where fetchpage_preprocessed would stop such fetches as new ones were started was revealed. The API to frames_abort_fetching has now been extended to include a 'stop file spooling too' flag, allowing a fix to be made by having fetchpage_preprocess's calls not set this (and it doesn't check the savelink flag is unset before proceeding, since frames_abort_fetching does that implicitly now). Had left the RAM transfer buffer at 16 bytes (from testing) accidentally... Oops. Upped it to 4K. In addition, when loading data by RAM transfer, the browser didn't notice if a RAMFetch bounced during the transfer. It would be treated as a 'first' RAMFetch bounce, basically, and try to go to file transfer - oops. Fixed.

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!

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...
