[HECnet] RSTS/E started emitting "?EVTLOG (BLDNIC) -- %Integer error" messages

Hmm, if I'm understanding you correctly, then I'm not sure I would agree with you, 100%.? Recall the binary file I build?? This is dumped /directly/ into the monitor on reboot, there is no re-parse of the .T20 file; that only ever gets looked at precisely once. 21:05:28 USER?? SETNODE>*Save /NO-ACCESS /RESTRICTED 21:05:28 USER 21:05:28 USER?? [Fork SETND2 opening ? for writing restricted] 21:05:28 USER?? [Saving to binary file: *TOMMYT:<SYSTEM>NODE-DATA.BIN.1 *;PROCESS-ONLY-JFN:2 ;RD ;WR ;BSZ:36 ] This resulting .BIN file is ? the size of the .T20 file and goes into the monitor with a single NODE% JSYS, so there is only a single context switch.? The monitor does some validation of the entries before putting them into the hash table.? Naturally, I can also read the binary file and reconstruct the text file: SETNODE>GET (binary node definition file) *SYSTEM:NODE-DATA.BIN*/no-ACCESS /pagE-MAP /unrESTRICTED-READ /prelOAD Mapped 4 pages, 1830 Words, 915 Nodes. SETNODE>RECONSTRUCT (node keyword tables from binary table) /silENT [Closed log file: NUL:] I think the only faster way to do this would be to save the Monitor's volatile hash table directly to disk and read it back in on reboot.? If you check it as you read, then you might be back down to the .BIN file input speeds, which are clearly faster than doing the parse of the .T20 file; a lot faster. If you don't check then you might not be able to boot if it gets funny data in it.? Or maybe you could do minimal checking. However, I do think that the idea of a seperate volatile and permanent database is a very good idea.? You could do that with my SETNODE rewrite, but /only/ if /nothing/ else was touching either node store (like a remote NCP).? I think the other implementations are probably far cleaner in this regard. ------------------------------------------------------------------------ On 11/11/21 4:59 PM, Johnny Billquist wrote: > This is actually one thing I've found annoying with TOPS-20. > > With VMS, as well as PDP-11 OSes, you have both a volatile and a > permanent database. > > For the volatile db, the commands are: > SET > CLEAR > SHOW > > For the permanent db, the commands are: > DEFINE > PURGE > LIST > > Exactly the same syntax and everything, but one affects what you have > right now, and the other only affects what is stored permanently, and > is used when the system starts to populate the volatile db. > > With TOPS-20 seems you always have to run through the definitions when > you boot. > > ?
