[Nut-upsdev] [RFC apcsmart V3 00/18] apcsmart driver updates

Sorry for a bit longer delay than I anticipated, I was stuffed with the work.

This is the next iteration of the patch adding some functionality to apcsmart
driver, and relying on 'ignorelb' recently added.

Follow up from previous thread:

http://www.mail-archive.com/nut-upsdev at lists.alioth.debian.org/msg02331.html


Main differences is that V3 is split into many small patches, so the reviewing
changes should be much easier. There're also a few additional changes in
later
commits.

I'll do more tests in the following week, though everything seems to be
working
fine so far. Still to do: manpage updates.


Michal Soltys (18):
  drivers/apcsmart.h: comsetics - adjust tabs and add basic modeline
  drivers/apcsmart.h: add compat hardware, add commands
  apcsmart: remove APC_IGNORE
  drivers/apcsmart.c: cosmetics
  drivers/apcsmart: adjust ignored chars and handle over/~over
  drivers/apcsmart.c: remove status_commit() from update_status()
  drivers/apcsmart: adjust how firmware_table_lookup() handles 'b' and
'V'
  drivers/dstate: add dstate_getflags()
  drivers/apcsmart: add APC_USERCTRL and APC_CRUCIAL
  drivers/apcsmart.c: add sdcmd_*() sdok()
  drivers/apcsmart.c: add upsdrv_shutdown_advanced() and
upsdrv_shutdown_simple()
  drivers/apcsmart.c: adjust upsdrv_shutdown()
  drivers/apcsmart.c: update in-driver help information
  drivers/apcsmart.c: update version and authors
  drivers/apcsmart: remove CMD_IGN_CHARS
  drivers/apcsmart.c: don't overuse UPSDELAY
  drivers/apcsmart.c: add ser_flush_in() in setver_enum() and do_cmd()
  drivers/apcsmart: use STAT_INSTCMD_{HANDLED,FAILED} for sdcmd_*()

[Nut-upsdev] [RFC apcsmart V3 03/18] apcsmart: remove APC_IGNORE

APC_IGNORE was only used in query_ups(), and could be easily handled by
APC_PRESENT and different tests/sets. Also, APC_IGNORE's comment in .h
was a bit misleading.

[Nut-upsdev] [RFC apcsmart V3 05/18] drivers/apcsmart: adjust ignored chars and handle over/~over

'*' is no longer ignored - this is old APC models' "OK"
reply to some of
the shutdown commands.

'?' and '=' are responsible for alerting about overload (among
supposedly other things), so we handle them now.

[Nut-upsdev] [RFC apcsmart V3 08/18] drivers/dstate: add dstate_getflags()

In cases such as immutable flag over readable value, we have
to be able to acquire this info at driver level (to e.g. avoid
polling, if user defined a variable with 'override' prefix).

[Nut-upsdev] [RFC apcsmart V3 09/18] drivers/apcsmart: add APC_USERCTRL and APC_CRUCIAL

Prepare the code for proper handling of override.* variables.

APC_USERCTRL - allows permanent overriding of the variable. Meaning
even if the ups supports reading and/or writing it, the driver will not
allow it (actually it will behave as if the variable wasn't supported at
all). This guarantees that the value set by the user in the
configuration file is respected.

Currently only battery.runtime.low overriding is allowed, which is
necessary for proper functioning of ignorelb (if user decided to
override that variable).

APC_CRUCIAL - this flag enforces checking if the variable is actually
supported.

Additionallly - the driver will ask user about reporting UPS models,
which don't support command querying, but do support firmware query - in
the other words - models which are not present in the compatibility table,
but should be included there.

oldapcsetup() also checks for presence of battery.charge now.

This delay is meant for multicharacter commands, besides
we always guarantee delay by other means - so do the stuff properly.

[Nut-upsdev] [RFC apcsmart V3 18/18] drivers/apcsmart: use STAT_INSTCMD_{HANDLED, FAILED} for sdcmd_*()

As we want the user to be able do issue all shutdown methods manually,
adjust sdcmd_*() to use STAT_INSTCMD_{HANDLED,FAILED}, so they can
be used directly.

Also minor text corrections, and APC specific command renames.

Thanks for these patches. One remark though, is that we prefer if you  
send patches as attachments rather than inline them. Inlining them  
means we have to painstakingly extract them from the messages (making  
sure the formatting is not changed along the way) and applying them in  
the hope we didn't miss a part. Attaching them means that we can  
simply save the attachment and apply that to the trunk immediately.

Best regards, Arjen
