087fd30e83 Make sure stderr is still unbuffered after the reopen. This is 
likely unnecessary, but belt.  Suspenders.

09c6b73f56 New dist tapes. Note man page in emu doco section. 
Link to four distribution tape sets on sysovl.
In the emulator doco paragraph, mention the man page.
Hacked on line wrap until I decided it was better to do it in vi.

4a6a3aff5d em: add macro to force gcc to obey inline keyword 
History: when the emulator was first developed on OSX 10.4 (PowerPC),
the inline keyword was added by profiling with Apple's pretty
fantastic Shark profiler.  Apple's version of gcc had an -fobey-inline
switch that the makefile used to force gcc to obey the inline keyword.
This macro does the same thing

9054d69446 em.c, etc: use gv.xxx instead of gvp->xxx for 13% speed increase, from 
37.5 Prime MIPS on Linode VM to 42.5 MIPS.  gvp-> was faster on the
PowerPC architecture when gvp was kept in a dedicated register, but
that does not apply to Intel.

Old:

Timing CPU,  20.0 ticks per second...
  35.3 Prime MIPS for 16-bit ADD loop
  40.0 Prime MIPS for 16-bit MPY loop
  42.1 Prime MIPS for 16-bit DIV loop
  21.4 Prime MIPS for 32-bit ADD loop
  30.8 Prime MIPS for 32-bit MPY loop
  28.6 Prime MIPS for 32-bit DIV loop
  57.1 Prime MIPS for 16-bit X=0 loop
  44.4 Prime MIPS for 32-bit X=0 loop
  37.5 average Prime MIPS

New:

35adf0905a devpnc.h: moved xmit setup code from OTA to pncxmit; 
move loopback handling to pncxmit1 so it is used for broadcasts;
added reason to disconnects for better logging;
change some traces to prints for better logging;
my node is always authenticated

cd351506ea devpnc.h: drive connections from PNC xmit requests rather than 
ring.cfg, for faster start times of large rings
 2020-02-27 20:00:58 -05:00
Jim
120079666f devpnc.h: expand listen backlog for big rings, use TCP_DEFER_ACCEPT so 
Linux holds onto connections until the uid is sent.  Otherwise, the
delay between making a connection and sending the uid will be larger
than MAXACCCEPTTIME, causing large rings to fail
 2020-02-27 11:53:07 -05:00
Jim
bf3c1a3df2 devpnc: after accept, make fd non-blocking to avoid deadlock when multiple emulators make connect requests, then accept(), then block reading uid that never comes. 2020-02-26 21:39:21 -05:00
