  • The Python 2.3 Method Resolution Order

    ...merge(O,O) which gives O. Therefore L[B] = B D E O Using the same procedure one finds: L[C] = C + merge(DO,FO,DF) = C + D + merge(O,FO,F) = C + D + F + merge(O,O) = C D F O Now we can compute: L[A] = A + merge(BDEO,CDFO,BC) = A + B + merge(DEO,CDFO,C) = A + B + C + merge(DEO,DFO) = A + B + C + D + merge(EO,FO) = A + B + C + D + E + merge(O,FO) = A + B + C + D + E + F + merge(O,O) = A B C D E F O In this example, the linearization is ordered in ...

  • Release – Python 2.3.0

    Version: None

    Released: July 29, 2003

    This is a patch release which supersedes earlier releases of 2.3. Important: This release is vulnerable to the problem described in security advisory PSF-2006-001 "Buffer overrun in repr() of unicode strings in wide unicode builds (UCS-4)". This fix is included in Python 2.4.4 and Python 2.5. If you need …

  • Python 2.3

    ...merged back into the main Python distribution and takes the place of the old IDLE release. What's New? See the highlights of this release. Andrew Kuchling's What's New in Python 2.3 describes the most visible changes since Python 2.2 in more detail. A detailed list of the changes is in the release notes, or the Misc/NEWS file in the source distribution. For the full list of changes, you can poke around in CVS. The PSF's press release announcing 2.3. Documentation...

  • Unifying types and classes in Python 2.2

    ...algorithm that's currently implemented, but its description of the algorithm is pretty hard to grasp - I had originally documented a different, naive, algorithm and didn't even realize that it didn't always compute the same MRO until Tim Peters found a counterexample. More recently, Samuele Pedroni has found a counterexample showing that the naive algorithm fails to maintain monotonicity, so I won't even describe it any more. Samuele has convinced me to use a newer MRO algorithm named ...

    ...algorithm that's currently implemented, but its description of the algorithm is pretty hard to grasp - I didn't even realize that the algorithm above doesn't always compute the same MRO until Tim Peters found a counterexample. Fortunately, counterexamples can only occur when there are order disagreements in the inheritance graph. The book outlaws classes containing such order disagreements, if the order disagreement is "serious". An order disagreement between two classes is serious wh...

  • Computer Programming for Everybody

    ...merge their changes back when the primary application itself has been modified or updated by the vendor. A key to this approach is identifying each version of software and a simple language for describing its properties and dependencies. For example, we intend to improve version control systems so that they track changes at different abstraction levels and granularities than current systems, e.g. labeling changes based on the features they implement instead of the source files (or parts o...
