We need an iBrowse replacement for 68k!!!

Processing the exec list header as a node is basically what I was trying to say and it's a common problem with exec lists. Do the list nodes have many data (non-link) pointers? If so, would it be easy to define data (like padding) and clear the memory below the List or MinList header structures? Then if the list header was used like a node for a pointer, it would usually generate a MuForce/Enforcer hit to address 0 which we should be able to catch.

OK, well I'm pretty sure Buzz's code is OK as it's in use elsewhere, but I've added some padding to the list structure in the function which usually allocates the memory for my lists, so if it is still reading the list header anywhere we'll see it.

The RA_HandleInput problem is tough because there is a lot of abstraction in this area. This is where it would be nice to have line debug and know the source lines. I can normally pretty well compare the C source to assembler but not here.

I added some more debugging to try and track this down, and it seems to be consistently crashing after RA_HandleInput now, so I'm thinking I've fixed this.  You'll see how the function is called on the debug now, which might help.

Could you have a look at the new build and see what you get?  Thanks for your help!

edit: fixed build as an earlier fix got reverted accidentally

somehow my last post got lost for being too long so i repost my current log truncated at the beginning once again. running in winuae you can see all the details in winuae debugger, but i dont know how to post them here.

edit: fixed build as an earlier fix got reverted accidentally

I'm working with the NetSurf executable which is now 5920060 bytes. A "Scanning fonts..." requestor now opens and it gets almost 60% of the way through the top guage and barely started on the bottom guage as it scans my large collection of fonts before I get an address error exception from the bullet.library. The return value on the stack from an RTS (Return from Subroutine) is 0xffffffff (-1 signed) and the PC must maintain even alignement thus the address error. The last debug output is:

Code: [Select]

amiga/font_scan.c ami_font_scan_fonts 293: Found 0 new glyphs (total = 474)
amiga/font_scan.c ami_font_scan_fonts 290: Scanning NewBrunswick_BoldItalic
amiga/os3support.c OpenOutlineFont 105: Using font engine bullet
amiga/font_scan.c ami_font_scan_fonts 293: Found 0 new glyphs (total = 474)
amiga/font_scan.c ami_font_scan_fonts 290: Scanning NewBrunswick_Italic
amiga/os3support.c OpenOutlineFont 105: Using font engine bullet

It's strange that bullet.library didn't crash with the NewBrunswick_BoldItalic font before this. Maybe this font is from Wordworth?

Edit: I tried the NewBrunswick_Italic font in WordWorth to make sure it wasn't corrupt and it worked fine. I then retried NetSurf and didn't have any problems in the font scanning this time.

I am past the screen and window open and I believe farther than ever. The PC seems to have gotten lost and points to 0xc0. The last debug output is:

The last value which looked like a return value that I could find on the stack would return to ami_bitmap() in /amiga/plotters.c. The return would have been from graphics.library BltMaskBitMapRastPort() near the bottom and may indicate a problem with this function call but is not reliable. I would have to catch the process before this to be more certain but it's a possible lead.

[wawrzon]

here it opens window as well, i give it plenty of stack to be sure, but is there a way to redirect the netsurf debug to serial?

Blimey you're good!

I'd managed to transpose the last two arguments of BltMaskBitMapRastPort (only the OS3 build uses it otherwise I'd have noticed sooner).  I've fixed it now and put a new build up.

I expect the error output from NetSurf -v is going to stderr instead of stdout as I tried to redirect it and it didn't work. If stdout was used it would be possible to use:

Code: [Select]

>NetSurf -v >SER:

I don't know any way to redirect stderr with AmigaDOS though.

Blimey you're good!

Good. My Amiga was in a stable condition up to this problem. NetSurf seems to use a lot of chipmem though (1-1.5MB on my P96 RTG Amiga). I hope it doesn't need any more big chunks or there could be failures due to low mem conditions and fragmentation. I'll take a look at the new executable. At some point we should break through the startup and have a running NetSurf.

Edit: I get further now but to another freeze:

image_cache_add() OK
content_set_ready() OK
content_set_done() Freeze!!!

Edit Final:

It looks like the freeze is from BltMaskBitMapRastPort() of gui_window_set_icon() from gui.c.

A0 = scrbm = 0x973a574
D0 = srcx = 0
D1 = srcy = 0
A1 = destrp = 0xa43b388
D2 = destX = 0x9e
D3 = destY = 0x14
D4 = sizeX = 0x10
D5 = sizeY = 0x10
D6 = minterm = 0xe0
A2 = bltmask = 0

It looks to me like the minterm and bltmask arguments are switched for BltMaskBitMapRastPort(). Is that what was fixed for the other BltMaskBitMapRastPort() in /amiga/plotters.c?

NetSurf -v >SER:

would be my expectation as well.

i have an impression too, that chipmem is being eaten, need to verify though. perhaps the memory need s to be explicitly defined in the source.

[chris]

I don't know any way to redirect stderr with AmigaDOS though.

On OS4 it's *>SER:
I think that's new though.

Good. My Amiga was in a stable condition up to this problem. NetSurf seems to use a lot of chipmem though (1-1.5MB on my P96 RTG Amiga). I hope it doesn't need any more big chunks or there could be failures due to low mem conditions and fragmentation.

It uses an offscreen buffer for rendering, which defaults to the same size as the screen.
edit: it's flagged as BMF_DISPLAYABLE so will be using chip mem, however it doesn't get displayed itself, only blitted to a displayed bitmap, so I might be able to remove this flag? (edit2: I've removed it and it seems happy on the OS4 build)

You can reduce it with the following options in Choices:
redraw_tile_size_x:nnn
redraw_tile_size_y:nnn
(replacing nnn with your chosen size)

It might also be a good idea to use Simple Refresh windows, with:
window_simple_refresh:1

I'll take a look at the new executable. At some point we should break through the startup and have a running NetSurf.

Hopefully!  I actually got it running a minute ago long enough to get into the menu and call up the hotlist.  I'm still not getting any rendered output on screen which is a bit concerning.

How does NetSurf render?

Does it only use Reaction for the gadgets outside the main window and just treat everything inside the main display area as a large bitmap?

[QuikSanz]

@chris, matthey & wawrzon and anyone else involved,

You guys rock. Taking on a huge task and it's shaping up. Kudos's!

I don't think it is necessary to specify BMF_DISPLAYABLE for a bitmap that is never displayed on screen (a double buffering buffer would need it though). I believe you should use the displayed Window->RPort->Bitmap or Screen-RastPort->BitMap as the friend_bitmap for best performance (and no chip mem used with RTG) when allocating with AllocBitMap().

You can reduce it with the following options in Choices:
redraw_tile_size_x:nnn
redraw_tile_size_y:nnn
(replacing nnn with your chosen size)

It might also be a good idea to use Simple Refresh windows, with:
window_simple_refresh:1

Nice to know, I could have always lowered the resolution but I only selected 800x600x32 and some browsers today may have issues at 640x480. The simple_refresh option may end up being faster on a gfx board. I'd rather not go crazy with options until we get the basic NetSurf working.

Be sure to see my Final Edit from my last post to hopefully fix the last freeze.

There is a requestor which pops up asking for PROGDIR right around the time the screen opens. It doesn't seem to stop NetSurf or affect anything whether I choose a gadget or ignore it. Do you get the requestor? Any idea what is causing it?

II don't know any way to redirect stderr with AmigaDOS though.

With Os 3.9 and the shell from Os 3.9, it is "*>". Thus, "program *>foo" redirects the standard error to a file (or a device). Actually, it's in the manual. I wonder why so many people don't find the time to browse it for such questions.  To remember this, think of "*" as the console, thus "*>" (no space) redirects the console. Additional "reidrection" instructions are "*>>" append to stderr, and "*" "redirect stderr to stdout".

[guest11527]

Unlike what you see in the post, redirect stderr to stdout is "star less than greater than", except that this ^$*@!! HTML editor "eats" my post.

Yes.

[NovaCoder]

Yes.

Cool, we should be able to do a C2P straight to the main bitmap then for extra speed

[chris]

If you mean rendering direct to the window, I've tried that and it gives all sorts of problems.  There's an option to enable it (I think.. or maybe I removed it again), but it's only there to aid debugging.
