7256f6b3ab db close routine actually writes data out to disk; return value was
not being checked.  Change code to fail if db->close errors.

eb0abfcc18 Allow comments in password database. The comments are copied from
the password file into /etc/master.passwd and optional (-p) into
/etc/passwd. Enable this feature with the compile
option -DPASSWD_IGNORE_COMMENTS.

The character `#' introduces a comment. Leading spaces and tabs are
ignored: '^[ \t]*#.*\n$'

Count an empty line - only spaces, tabs or newline - also as a comment.
An empty line at the bottom of /etc/master.passwd is a common
novice error and increased my mail load: '^[ \t]*\n$'

8839484b47 Begin closing out PR #1519 (this requires a change to chpass too,
and both changes need to be pulled into the stable branch). The
problem here is that when pwd_mkdb creates /etc/passwd, it turns
empty UID and GID fields into zeroes. To fix this, we check the
_PWF_UID and _PWF_GID bits in the pw_fields flag: if the bits
are not set, we print an empty field instead of a zero. This way,
you don't get zeroes in the UID or GID fields unless you explicit
want them.

79a1b8d9e2 Implement incremental passwd database updates. This is done by ading a '-u'
option to pwd_mkdb and adding this option to utilities invoking it.
Further, the filling of both the secure and insecure databases has been
merged into one loop giving also a performance improvemnet.
Note that I did *not* change the adduser command. I don't read perl
(it is a write only language anyway).
The change will drastically improve performance for passwd and
friends with large passwd files. Vipw's performance won't change.
In order to do that some kind of diff should be made between the
old and new master.passwd and depending the amount of changes, an
incremental or complete update of the databases should be agreed
upon.

6ec733f455 NIS cleanups and fixes, the next generation, continued.
pwd_mkdb.c:

- Don't save the PLUSCNT and MINUSCNT tokens: we don't need them anymore.

- Count the + and - entires for NIS together instead of counting + and -
  entries seperately. Index all special NIS entries using new _PW_KEYYPBYNUM
  token.

pwd.h:

- Remove the PLUSBYNUM, MINUSBYNUM, PLUSCNT and MINUSCNT tokens and replace
  then with a single _PW_KEYYPBYNUM token.

d038db90e8 Re-enable +::::::::: wildcards that I had previously disallowed.
Note: if you put +::0:0:::::: in /etc/master.passwd as your only NIS
entry, it will cause all NIS uids and gids to be remapped to zero. This
is *intentional*. That's the way it's supposed to work. Enabling NIS with
no remapping at all is done with +:::::::::, not +::0:0::::::. Similarly,
+:::::::::/bin/csh will remap the shells of all NIS users to /bin/csh.
Or, you could do +wpaul:::::::::/bin/csh to remap NIS user wpaul's shell
to /bin/csh but leave everyone else alone.

34876b9137 Summarily enable YP as soon as any a '+' is detected instead of generating
special values when +user substitutions are in effect. The new getpwent
code can handle all the special cases itself now.

ad5d3ccd4d - Add support for embedding special entries in the password databases
for +@netgroup/-@netgroup entries. This saves the getpwent functions
from having to do all the work.

- Fix potential bug: when pwd_mkdb writes the YP-enabled flag to the secure
password database, it uses the wrong database descriptor. (It uses the
descriptor from the non-secure database, which is already closed by the time
things are being written into the secure dastabase).

28ca30918a Maintain pw_fields, and output same to password database.
!!!!!!!!
NB
!!!!!!!!
You MUST pwd_mkdb /etc/master.passwd before attempting to use the new
libc, or things may go wrong.  (I doubt anything actually /will/ go
wrong, but the actual behavior is undefined.  YOU HAVE BEEN WARNED.)
The database format is, however, backwards-compatible, so old executables
will still work.
