  109. Subject: [PATCH 02/11] Make Symbian follow Windows code in temporary path
  110.  generation
  111.  
  112. On the one hand, we stop using OpenC here. On the other, we no longer
  113. use an atomic create and obtain file handle API -- just as we don't on
  114. Windows yet.
  115.  
  116. This is a stepping stone to removing back and forth conversions of path
  117. names when generating unique names and also towards the use of native
  118. APIs for creating and obtaining a file handle atomically.

  171. Subject: [PATCH 03/11] Use QStringBuilder when copying template for
  172.  modification
  173.  
  174. This avoids modifying the original string in the case where a
  175. placeholder marker is not found. By marking the variable const we
  176. further avoid checks on the reference count and detaches, also allowing
  177. us to safely reuse it later in the function.
  178.  
  179. The new approach also fixes an issue where suffix wasn't empty, but the
  180. toLocal8Bit conversion would be. This resulted in a buffer overflow
  181. inside createFileFromTemplate.

  307.  file name
  308.  
  309. With minor adjustments, createFileFromTemplate is made to work directly
  310. on (UTF-16) QString data, which is already in the native encoding for
  311. Windows and Symbian. This is possible because the function only fills
  312. out the placeholder sub-string, without touching adjacent characters.
  313.  
  314. This eliminates unnecessary conversions on those platforms.

  484. Subject: [PATCH 05/11] Atomic implementation of create file and obtain handle
  485.  for Win/Symbian
  486.  
  487. Besides generating a unique name, createFileFromTemplate now also
  488. acquires a file handle on all platforms. The file engine's native handle
  489. is passed by reference and modified in place.
  490.  
  491. This fixes a long standing security issue on Windows.
  492.  
  493. On Windows and Symbian platforms we directly use the "native" file path
  494. when processing the template and generating the unique name. Since the
  495. native encoding is known, conversions at this point are safe.
  496.  
  497. Errors other than "file exists" are propagated to Q(Temporary)File,
  498. and result in a failure in open(). The changes also unify error handling
  499. and should give consistent behaviour across all platforms.
  500.  
  501. Worthy of note, there's a change in behaviour on Windows and Symbian:
  502. fileNames returned by QTemporaryFile on Windows and Symbian are always
  503. absolute after open has been called. This has to do with how
  504. QFileSystemEntry::nativeFilePath works on these platforms. (Test was
  505. updated to reflect change in behaviour.)

  921. Subject: [PATCH 08/11] Use "native paths" on POSIX platforms as well
  922.  
  923. And don't rely solely on "local8Bit" conversions.
  924.  
  925. QFile defines an API for overriding how encoding conversions are done
  926. for filenames. In generating unique names, QTemporaryFile ignored that
  927. API and hardcoded the use of local 8-bit, implicitly assuming that that
  928. was appropriate.
  929.  
  930. With this change, we switch that assumption to one where user supplied
  931. encoding function keeps the byte value of 'X' and '/', also assuming
  932. that encoded 'X' takes up a single-byte (i.e., the byte sequence for
  933. "XXXXXX" remains unchanged).
  934.  
  935. There was also, and there still is an assumption in name generation that
  936. byte values for ASCII alpha-numeric characters are valid in the "native"
  937. encoding.
  938.  
  939. In practice this change is compatible with UTF-8, Latin-1 and other
  940. ISO/IEC 8859 encodings. At any rate, it's very likely that only UTF-8 is
  941. relevant here.

  1023. Subject: [PATCH 09/11] Fix QTemporaryFile regressions and new found issues
  1024.  
  1025. With this change, the file template is always processed in original
  1026. QString format. Trying to generate native paths before adding a missing
  1027. placeholder mask could change the meaning of templates, such as "." and
  1028. "..", which are now tested to mean "..XXXXXX" and "...XXXXXX",
  1029. respectively.
  1030.  
  1031. After ensuring the template includes a placeholder mask, the path is
  1032. converted to a native *absolute* file path and the mask is sought for
  1033. again. On Windows, native paths were already absolute. On Symbian, we'd
  1034. need at least a clean path, as "." and ",," are not natively understood.
  1035.  
  1036. There is a requirement that the placeholder mask /XXXXXX+/ makes it
  1037. through this conversion unaltered, which relaxes prior requirements on
  1038. *nix platforms. On Windows and Symbian the conversion is under Qt's
  1039. control and not user-configurable.
