Fri Apr 26 03:24:32 PDT 2002 malcolm * Fix a bug in hat-trail related to the file format. * getResult() now takes a boolean to determine whether to stop if it finds a Hidden. The rule is that a direct call of getResult() (i.e. to find the RHS of an equation) should stop if it immediately finds a Hidden, because the full result is not known. However, a recursive call of getResult() within itself should follow Hidden pointers, because if we are already inside an application, then the result of the Hidden is relevant. Also, in artutils.[ch], introduce a second file handle for the .hat file. One is for sequential access, the other for random access.

patch applied (hat): Show values of type IO as Abstract " IO" .
by Malcolm Wallace 10 Oct '06

Tue Apr 23 03:02:19 PDT 2002 olaf * Show values of type IO as Abstract "IO". Values of type IO used to be of the form `hidden applied to lambda'. Showing Abstract IO instead is clearer (value of an abstract type) and does not contain less information. It is still possible to ask for the parent of Abstract IO.

patch applied (hat): Improved speed of writing new trace.
by Malcolm Wallace 10 Oct '06

10 Oct '06

Thu Apr 18 09:54:39 PDT 2002 olaf * Improved speed of writing new trace. Introduced buffer to defer updating (entering and result) and then do the updates in bulks. Improves Adjoxo from 30s to 24s. Independent of buffers size between 16 bytes and 128 Kbytes. Only worse for smaller buffers. Main effect is probably halfing of number of seek operations. Then added some update avoidance: Updating of result first tests (linear seach) if such an update is already in the buffer and then overwrites it in buffer. Improves Adjoxo further to 20s for small buffers (32-64 bytes). Larger buffers increase linear search unduly, although system time is still reduced further. Finally, make linear search through buffer backwards, because overwritten entry is most likely the most recently entered one. Improves Adjoxo further to 17.5s for buffers between 1KB and 4KB. Clearly similar to previous times for small buffers. Slight increase for larger buffers. M ./src/hatlib/hat-c.c -35 +92 M ./src/hatlib/hat-c.h +3

patch applied (hat): hat-stack now works with the new file format.
by Malcolm Wallace 10 Oct '06

Thu Apr 18 08:09:02 PDT 2002 malcolm * hat-stack now works with the new file format. In artutils.c, the getResult() routine now follows the result pointer chain to the end. Also, readTraceAt() now correctly gets the result of every subexpression in an application. M ./src/hattools/artutils.c -90 +152 M ./src/hattools/hat-stack.c -2 +6
