implemented for du.c revision 1.25 :
Use open address hashtable with multiplicative double hash probing
and exponential hashtable growth for tracking previously seen inodes.
This replaces the O(n^2) behavior of linkchk() with an implementation
that should be O(n*logn)
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).
Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.
Fixes PR's: PR#17762 PR#25944
round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
information and a link to the appropriate fsinode, and `fsinode' contains
the inode information and a reference count. multiple fsnodes may point
to the same fsinode. this replaces the 'dup' pointer in the previous code.
check on the correct node
- apply_specentry(): if this node is a duplicate of another, apply the
changes to the `master' entry instead of this one.
- fix inotype() to DTRT
- comment out some debugging info that is too verbose
It doesn't need any special privileges or kernel devices.
Only ffs image creation is supported at this time, although makefs has been
designed to allow the addition of other file system formats by writing new
back-ends.
This program was designed & implemented by Luke Mewburn of Wasabi Systems.
