John Fremlin's blog: manardb not borked

manardb had a teething problem on release, because it depended on the mmap in the osicat library, which was broken, giving this error

The value -134328320 is not of type (UNSIGNED-BYTE 64).
   [Condition of type TYPE-ERROR]
Backtrace:
  0: (OSICAT-POSIX:MMAP #.(SB-SYS:INT-SAP #X00000000) 4096 3 1 4 0)
  1: (MANARDB::MTAGMAP-OPEN #<MANARDB::MTAGMAP >)[:EXTERNAL]

This small issue (of signedness) is fixed in the osicat Git HEAD, and I'd like to opine that osicat is a nice clean library that more people should use instead of doing their syscalls by hand.

Anyway, the tests all pass

Note that SBCL does not seem to support bound inline declarations (in contravention of the spec, unless I am misreading it), so it gives a style warning.

manardb/src/box.lisp:65:19:
  style-warning: undefined function: MANARDB::ELEM

This is quite harmless.

[manardb is a memory-mapped persistent database for Lisp. It has an extensive test suite and some documentation and is being used right now. Give it a shot!]
