blymn 395d5f8537 Fix for PR lib/56298
Remove the DIAGASSERT for str being NULL in the puts/putp functions,
add protection so that the functions just return OK if str is NULL.
This prevents the assert firing when libcurses passes through a NULL
due to an undefined terminfo entry.

rillig b18bad8f33 libterminfo: remove redundant lint annotations
Since 2021-02-28, lint does not warn about constant conditions if they
involve sizeof.

The fallthrough annotations have never been necessary for case labels
that directly follow each other.

roy f236a33b97 libterminfo: cast to uint16/32_t before conversion to preserve negativity
Otherwise the ABSENT_NUMERIC(-1) or CANCELLED_NUMERIC(-2) will be converted
incorrectly to size_t and then down to uint16/32_t.
Picked up by DIAGNOSTIC builds.

Thanks to Michael Forney for the fix for PR lib/52293.

roy 9e387da605 terminfo: Add guards to optionally build parts of libterminfo
Reading from a database is now optional.
Compiling terminfo descriptions (including from $TERMINFO) is now optional.
Compat support is now optional.

This removes 17k on amd64 from the binary size, which allows it to be used
again on space constrained ramdisks.

roy 5159a4258d terminfo: Promote a terminfo description to v3 when required
Blindly scanning the capabilities for # and checking that the following
number is bigger than a short isn't reliable because this could be a
string value:

SomeString#1234

Instead, if we process the numeric as normal and if it's value is too big
for v1 then promote the record to v3.

christos 1d30fdae10 Introduce a bunch of inline functions and utilities to avoid code duplication. 2020-03-27 17:39:53 +00:00
christos 3958d16a96 As described in tech-userlevel:
- Modify the writing code to only write entries in the new
  format for the terminal descriptions that require it.
- Store new format entries as <name>@v3
- Store old format entries with clamped values as <name> for
  backwards compatibility
- Lookup first <name>@v3 and then <name> if that is not found.
- Don't create terminfo2 anymore; old programs keep working with
  clamped entries, and new programs be able to use the wide
  fields with using the original db file.

roy aadfdb111b terminfo: promote numeric parameters from short to int
POSIX mandates implementations must support upto a short but may exceed it.
When NetBSD terminfo was implemented, no terminfo description used over
a short, but because ncurses has supported ints for some time, some now do.

Infact, such a terminfo description was imported where colour pairs for
screen-256color went up to 65536 which exposed a bug in the existing
implementation where it set to zero. Because the number might mean
something more than a range, we need to be able to store it accurately.

This requires a version bump because whilst the API hasn't changed thanks
to C int promotion, the ABI has. Also the underlying database structure
has changed as well - we now store the numeric paramter inside a uint32_t
field rather than a uint16_t one.
Whilst this change can still read the old style database, the old one
cannot read the new one and thus we now maintain the database as
terminfo2.cdb, leaving the old library and database alone so old programs
still work fine.

libcurses, libfrom, libmenu and libpanel have also been bumped to
accomoate this change.

roy 62c320f6cd terminfo: truncate numeric parameters to a short
Because that is what our API demands.
We should probably change to int when we next bump the API.

roy 2b9f5c3f2c Instead of poking in the binary blob to work out if this is our terminal,
assume it is and load it.
Once loaded then check it's really for us.
This allows us to work out if the indexed alias entry is correct we
this was not checked previously.

roy 5128a2ed79 POSIX says that use_env(3) must precede setupterm(3).
The former lives in curses.h, but the latter lives in term.h.

This is solved by moving the function to libterminfo.
Because the environment can affect the terminal capabilities for
lines and columns, it follows that the tty size should affect it to.
So move that code to libterminfo and adjust in libcurses.
