- Previously invoking a simulator with -T was the only way to invoke the
library tests for ALL devices. That still works now with the additional
flexibility to invoke a specific device's test from the sim> prompt.
- Adding TESTLIB help text encountered a maximum constant string length
limit in the C compiler. Reworked to allow multiple strings which are then
concatenated on the first HELP command invocation.
- Make all PDP11, VAX RP and RQ devices autosizing behave similarly
- Generalize the attach help to be specific to the device/system being
attached
- Remove the sim_disk_pdp10_* calls which weren't correct or needed
since sim_disk_attach_ex provides sector size which is used correctly
The sim_disk_pdp10_... API's specifically provide 1024 byte sector
interfaces for 64bit data.
Customize the attach help output to be more appropriate for the devices
in the running simulator and the device who's help is being displayed.
This allows the underlying disk container formats that that sim_disk supports
(VHD, SIMH or RAW) to be accessed from the PDP10 KS10 simulator, and later
on to Rich Cornwell's PDP10-KA, PDP10-KI, and PDP10-KL simulators.
Also provide a way to build so that the IPv6 fallback stubs can be tested on
systems with native IPv6 support when compiled with TEST_INFO_STUBS
defined.
Refactor in preparation for the addition of a Rev 3 simulator for the
3B2/1000 system.
This change also includes a full cleanup of the rat's-nest of includes
and externs that plagued the 3B2 simulator and made it difficult to
understand and maintain. Headers are now required in the following
order:
compilation unit -> "3b2_defs.h" -> {... dependencies ...}
Finally, HELP has been added to the CPU device.
Sequential devices (LPT, PTR , PTP, etc.) can be positioned to EOF.
Readable devices will encounter EOF on the next I/O operation.
Writable devices will append. Either APPEND or EOF produce
the same result independent of whether the device is opened for
oread or write.
Although these devices interpret a -A switch at attach time, they are not
sequential output devices and thus don't have an ambiguous interpretation
of the switch.
Incorrectly mentioned in #821
The -A attach time switch implicitly means to open files in append
mode.
Some devices used -A to indicate ASCII data or AUTOSIZE of disk or
fixed size tapes - DECtape. These devices are either read only devices
(Paper tape readers or card readers), so explicit forcing of the attach
to be -R avoids unexpected positioning errors. The random access
Disk and fixed sized tapes buffer the container contents in memory
so append mode isn't relevant, but care must be taken to assure that
the buffer reading starts at the beginning of the file without regard
to the explicit open mode.
As reported in #821
Outbound connections are rare and most may have wanted explicit blocking
behavior, so no one noticed the missing non-blocking case.
Any place which did do outbound connects have explicitly added
SIM_SOCK_OPT_BLOCKING so that the prior behavior is preserved.
The SIM_SOCK_OPT_BLOCKING flag is no honored as it was originally
intended to be.
