crash when importing files from directory with too long path on Windows

[vmario89]

Hi,

Plater.exe crashes unexspectedly when pressing the "Add part(s)" button. The fix seems to put the files to some directories up to shorten the path. I am using Windows 10 64 Bit Pro Version.

I made some testings where i put the file chainy_v2.stl some dirs up until it works instead crashing. I just renamed the paths because they contained some info i dont want to publish here.

• fail: C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\Gedöns\123456Design\Keyorganizer123456\STL Export\chainy_v2.stl
• fail: C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\Gedöns\123456Design\Keyorganizer123456\chainy_v2.stl
• fail: C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\Gedöns\123456Design\chainy_v2.stl
• fail: C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\Gedöns\chainy_v2.stl
• works: C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\chainy_v2.stl

maybe somebody has an idea how to fix it.
regards, Mario

some add. info: seems also happening if path + filename in total get too long

Can you try the binaries from here:

@combolek what fix did you make?

It can be also related to special chars (here the ö)

[vmario89]

Hi, thanks for the download @combolek . But the given executable has the same problem. Indeed i've overseen the special character Ö which is typical in europe. In general UTF-8 might be good solution because many countries have à á â and other chars in their daily used names.

I now renamed the folder and it works (but in my case a bad solution)

[Gregwar]

Ok @vmario89, I'm not saying you shouldn't use UTF-8 characters, but just trying to isolate what makes the program crash
Do you confirm that the same PATH with and without the special char have different behavior?

[vmario89]

hi @Gregwar, yes the "ö" in path is the problem. I tested it with

"C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\Gedöns\123456Design\chainy_v2.stl" -> fail
"C:\Users\mario\Seafile\cloud.123456-STLEXPOR.DD\Gedons\123456Design\chainy_v2.stl" -> good

regards, Mario

I was all wrong, ignore me.

For the native MSVC build the following workaround works for me:

--- a/gui/main.cpp
+++ b/gui/main.cpp
@@ -13,6 +13,10 @@ Q_IMPORT_PLUGIN(QWindowsVistaStylePlugin);
 
 int main(int argc, char *argv[])
 {
+#if defined(_MSC_VER)
+    // set default encoding for fopen/chdir/etc.
+    setlocale(LC_CTYPE, ".utf8");
+#endif
     QApplication a(argc, argv);
 
     QGLFormat glf = QGLFormat::defaultFormat();

@vmario89 can you try these binaries?

But even if this works, it's only a partial solution because it cannot handle command line arguments (so it won't work for the plater.exe command line app). Also, I think the official build uses mingw (?) and this solution does not work then either.

I figured out a better way to fix it, see PR #30. It requires Windows 10 1903 or later but it also handles paths on the command line.

@vmario89 can you try these updated binaries?

Stopped crashing for me with your latest updated binaries @combolek

[combolek]

Great, thanks for testing. Let's hope PR #30 will be merged.
