Chris Hanson [Sat, 9 Jan 1993 01:16:25 +0000 (01:16 +0000)]
This version of Edwin requires microcode 11.125 or later.  It should
be compiled with compiler version 4.97 or later, because its
performance depends on several new compiler optimizations.

* Major redesign of low-level insert and delete operations, the
  primary aim of which is to greatly improve performance:

  * Insert, delete, and move-point daemons flushed.

  * Limits that track the extent of the changes to a buffer between
    display updates are now per-buffer rather than per-window.  The
    windows are notified of these changes at display update rather
    than while the changes are occurring.

  * Calls to the primitives STRING-ALLOCATE, SUBSTRING-MOVE-RIGHT!,
    and SUBSTRING-MOVE-LEFT! have been replaced with calls to Scheme
    procedures that perform the same functions.  These new procedures
    avoid the cost of calling C code, which can be very high.  The
    latter two procedures use heuristics to decide whether it is
    better to call the C primitive or to do the operation in line.

* The undo subsystem has been reimplemented.  The new implementation
  is a near-exact translation of the new undo code from Emacs 18.56.
  The major features of this implementation are: unlimited undo memory
  for one undo step; significantly better performance; and much
  clearer implementation, reducing probability of bugs (the previous
  implementation is known to be buggy).

* The new implementation of STRING-ALLOCATE fixes the bug that caused
  the editor to go into an infinite loop when reading in a file that
  was too large to fit in memory.

* The MOVE-TO-COLUMN procedure had a problem because it was searching
  for the end of line in order to pass it as a limit argument to
  GROUP-COLUMN->INDEX.  In some cases, particularly paragraph fill,
  this changed a linear algorithm to quadratic.  This has been fixed
  by changing GROUP-COLUMN->INDEX to stop at end of line even if that
  is not the given limit.

* The DEFINE-NAMED-STRUCTURE macro has been changed to create an
  object like those created by DEFINE-STRUCTURE, so that the printer
  and pretty-printer will treat them in the usual way.

* The LINE-START and LINE-END procedures have been rewritten to make
  them faster.  These procedures are used in many places in the editor
  and must be fast.  The associated MOVE-VERTICALLY has been
  eliminated as it's no longer used.

* TRANSPOSE-THINGS has been rewritten so that it doesn't leave
  permanent marks attached to the buffer.

* HORIZONTAL-SPACE-START and HORIZONTAL-SPACE-END no longer look for
  the nearest line limit, since that was completely unnecessary.  The
  procedures that they call automatically stop at the line edge.

* BOCHSER code, which was not being loaded, is now also not compiled
  since it depended on the move-point daemons.

32 years agoComplete redesign of environment model and declaration parser. This
Chris Hanson [Sat, 2 Jan 1993 07:33:39 +0000 (07:33 +0000)]
Complete redesign of environment model and declaration parser.  This
was prompted by a bug that had been present since the original design;
the bug was inherent in the design, hence the need for a redesign.
The new design has the following features:

* The old design used a two-level environment model for the top-level
  environment, in which imported and global bindings were
  distinguished from top-level bindings appearing in the file.  The
  new design uses a single top-level environment for all bindings.
  This is the change fixed the bug, but introduced performance
  problems because the two-level design had a special hack for the
  global environment; the performance problems were fixed by:

* The new design uses a hash table to hold the bindings in (the model
  of) an environment frame when the number of bindings exceeds a
  preset threshold.  This allows very large environment frames to have
  reasonable access times, while avoiding the time and space overhead
  of the hash table for small environment frames; typically only a few
  frames will use the hash table mechanism.  The hash table uses open
  addressing with double hashing.

* Because ".ext" files are internal data structures that are written
  to a file, old ".ext" files are incompatible with the new scode
  optimizer.  In order to prevent lossage, ".ext" files have a new
  format, which contains a version number.  When the scode optimizer
  encounters an old ".ext" file, or a new one with the wrong version
  number, it will emit a warning and ignore it.

* Code that supported special "error combinations" has been removed,
  since these are no longer used.

* Code that generated ".unf" files has been removed.  Since several
  procedures with semi-public interfaces accept arguments or return
  values relating to these files, the procedures ignore such arguments
  and return dummy values.  The global variable SFU? has been
  eliminated.
