[Nel] 'data/' bug

Wed, 7 Mar 2001 14:25:17 +0100

Hi there!
+
+We, at last, understood the problem of the 'data/' bug on linux.
+In fact, in our rawdatafiles, there are some empty file names and in our
+program, we try to find where these files are located.
+For that, we use a function (CPath::lookup()) that tries to find the file in
+all directories provided before by the user.
+To know if a file exists, we try to open it and if the opening success, we
+return true (CFile::fileExists()).
+When the prog tries to find the file "", first it calls fileExists("") that
+returns false.
+Next step, it tries with the first directory in his list,
+fileExists("data/"+""); On windows, the OS can't open the directory
+("data/")
+so it returns false. On linux, it can, so it returns true and the program
+tries to read the directory as if it was
+a texture, and of course, it fails (end of file).
+
+We fixed the problem by adding this next line in the top of the function
+string CPath::lookup( const string& filename ) in path.cpp:
+
+ if(filename.empty())
+  throw EPathNotFound( filename );
+
+Of course, we put it on cvs and it will be synchronized this night (GMT+1).
