[sqlite] temp file directory

[weiyang wang]

hi,
i found the way to open a temp file is different from other files (.db files
or journal files)

open temp file: open with the relative path. and then point to the fullpath
while open other files: get the fullpath first, and then open.

codes are cited as below:


in pager.c
sqlite3pager_open()

 if( zFilename && zFilename[0] ){
   {
*      zFullPathname = sqlite3OsFullPathname(zFilename);
*      if( zFullPathname ){
*        rc = sqlite3OsOpenReadWrite(zFullPathname, &fd, &readOnly);
*      }
   }
 }else{
*    rc = sqlite3pager_opentemp(zTemp, &fd);
*    zFilename = zTemp;
*    zFullPathname = sqlite3OsFullPathname(zFilename);
*    if( rc==SQLITE_OK ){
     tempFile = 1;
   }

can anyone explain what is the concern here? this disorder affected my
porting layer.

thanks

wang
