infinite loops when bmd file does not contain a tex section

[lolRazor]

No clue why this isnt working

[Roseghost]

^ +1, no clue how to solve it

[niacdoial]

OK, I have no idea how I saw this issue (twice!) and never realised what the problem actually was (early End Of File) so, er… in BModel.py, now around line 464, there is a block of lines like this:

        while strTag != "TEX" and not br.is_eof():  # "TEX1 tag is the last one every time"
            br.SeekCur(iSize)
            streamPos = br.Position()
            strTag = br.ReadFixedLengthString(3)
            _ = br.GetByte()
            iSize = br.ReadDWORD()

try to add those two lines:

        while strTag != "TEX" and not br.is_eof():  # "TEX1 tag is the last one every time"
            br.SeekCur(iSize)
            streamPos = br.Position()
+           if br.is_eof():
+               break
            strTag = br.ReadFixedLengthString(3)
            _ = br.GetByte()
            iSize = br.ReadDWORD()

does it fix the problem? If not, is the error message at least different ?

[Th3DryZ69]

so I no longer have the error message when doing this, but I have Blender which loads indefinitely trying to load the file

[niacdoial]

…right. This might be another bug altogether. what does the stack trace look like when you do Ctrl-C in the terminal after it loaded for a while ? just to see what loop it might be stuck on.

[Th3DryZ69]

I open blender I load the file for a little while then I press ctrl+c?

[niacdoial]

yep! in a terminal/console window, Ctrl+C means "interrupt!" instead of "copy" You just need to actually show the terminal window first, with… I think the option is in the "windows" menu of the toolbar at the top of blender?

[Th3DryZ69]

here is the error

[niacdoial]

ok. now, just to know if the bug is in the python code or the C code, if you change the area of common.py around line 117 like this:

+   print("call start")
    temp = subprocess.run([exefile] + args, shell=False)
    if temp.stdout:
        log.info ("process output:\n %s", temp.stdout)
    if temp.stderr:
        log.error('process errors:\n %s', temp.stderr)
+    print("call end")

does blemd repeat "call start/call end" without stopping, or does it just freeze after saying "call start"?

[Th3DryZ69]

it does not write it in the console of blender it redoes the same thing as the screen above

[niacdoial]

oh sorry, I forgot to ask you to delete the images again. but er… how much did you wait before using ctrl+C? Because if it hangs even without calling the bundled C program, it might have been too soon.

[Th3DryZ69]

if i do nothing it keeps spamming in blender console (read ic)

[niacdoial]

ooooh! I see exactly where the bug is. er… would you be able to recompile the bmdview.cpp file into the bmdview.exe program if I asked you to? to know if I should send you the patch, or just put it in a commit. (probably not tonight though, it's getting late)

[Th3DryZ69]

I don't think so, I don't know much about coding

[niacdoial]

ok. er… dang, I just realised I won't have access to a windows machine for a while, so compiling it myself won't be easy. bluh.

[Th3DryZ69]

I'll look into how to do it

[niacdoial]

er… thanks!

[Th3DryZ69]

I've tried looking at several tutorials and I just can't do it.

[niacdoial]

ok, no problem. I'll see what I can do on my side of things.

[edbefee3-3888-462a-9411-741b7e9eb54e]

Well, i don't think that it not working with 2.77 is much of an "issue" anymore

[niacdoial]

yeah, the title needs to be revamped

[edbefee3-3888-462a-9411-741b7e9eb54e]

is there any BMD file without textures you can think of? i might try tweaking the code to fix this

[niacdoial]

oh, I know what fix can be done, I just don't have a way to re-compile the c++ file for windows systems anymore

[edbefee3-3888-462a-9411-741b7e9eb54e]

I'm trying to see if there's a different solution and that'd require a bmd file without textures

[niacdoial]

another solution would be to not call bmdview.exe whenever blemd detects that the Tex section is missing. (given that the first infinite loop can be solved with the patch in a message higher in this conversation)

[edbefee3-3888-462a-9411-741b7e9eb54e]

that's what I was thinking of, but i need a file to test it with

[niacdoial]

I don't think I have one, I just asked CrbzBrandon whenever I had a patch that I thought worked.

[edbefee3-3888-462a-9411-741b7e9eb54e]

Looking at the third image, it seems to be from pixelmon?

[edbefee3-3888-462a-9411-741b7e9eb54e]

the directory structure matches, and pixelmon did use .bmd at some point

[edbefee3-3888-462a-9411-741b7e9eb54e]

but it does not seem to be the same BMD as the one you're trying to load, I couldn't get STB or J3DView to view it either. the original BMDView also gets stuck in a loop.

[Th3DryZ69]

that's exactly what I'm trying to have also the model and texture of the pixelmon mod

[edbefee3-3888-462a-9411-741b7e9eb54e]

it's a completely different format. the pixelmon one has a blender signature in it, and doesn't have the magic J3D x bmd/bdl y at offset 0x00, a list of materials at the end, and the occasional "this is padding data"

[Th3DryZ69]

so there is no way to open them?

[edbefee3-3888-462a-9411-741b7e9eb54e]

Not that I'm aware of
