RE: Proposed magic number patch
Is there a "magic number registration authority" (or an equivalent) to be in touch with either before or after deciding on one? --ado

De facto, the known magic numbers are those interpreted by the Unix "file" command. There is a freeware version of this, which seems to be the latest, at ftp://ftp.deshaw.com/pub/file . The authors will accept magic number information in "/etc/magic" format, which they will propagate into the next release. A search of the current (3.22; January 1997) version reveals no conflicts (no magic numbers with "TZ" in them). The contact addresses given in the current version (3.22) are: Christos Zoulas <mailto:christos@deshaw.com> Mark Moraes <mailto:moraes@deshaw.com> They want to get lines of the following form: 0 string \x14\x1aTZ compiled time zone information 0 string \x89TZ\x0d\0x0a\x1a\x0a compiled time zone information I withdraw my proposal to insert a NUL into the magic number, as this will cause "file" to malfunction. When this list has settled on a magic number, ADO can drop them the appropriate line. -- John Cowan http://www.ccil.org/~cowan cowan@ccil.org e'osai ko sarji la lojban
They want to get lines of the following form:
0 string \x14\x1aTZ compiled time zone information 0 string \x89TZ\x0d\0x0a\x1a\x0a compiled time zone information
I already sent them lines of the following form: #------------------------------------------------------------------------------ # timezone: file(1) magic for timezone data # # from Daniel Quinlan (quinlan@yggdrasil.com) # this should work on Linux, SunOS, and maybe others 0 string \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\1\0 timezone data 0 string \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\2\0 timezone data 0 string \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\3\0 timezone data 0 string \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4\0 timezone data 0 string \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\5\0 timezone data 0 string \0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\6\0 timezone data which I snarfed from, I think, a Linux distribution (Debian?). No guarantees that it's the best possible choice, although it does manage to get the right answer on a SPARC/Solaris 2.5.1 system (on the time zone data files that come with Solaris 2.5.1), except for the "Eire" compiled file.
