What it is:
A library for reading and writing various streaming archive
formats, especially tar and cpio. Being a library, it should
be easy to incorporate into pkg_* tools, sysinstall, and any
other place that needs to read or write such archives.
Features:
* Full automatic detection of both compression and archive format.
* Extensible internal architecture to make it easy to add new formats.
* Support for "pax interchange format," a new POSIX-standard tar format
that eliminates essentially all of the restrictions of historic formats.
* BSD license
Thanks to: jkh for pushing me to start this work, gordon for
encouraging me to commit it, bde for answering endless style
questions, and many others for feedback and encouragement.
Status: Pretty good overall, though there are still a few rough edges and
the library could always use more testing. Feedback eagerly solicited.
The default is to be backwards compatible and non-KNF (use the same
indentation for locals as for globals; -ldi0 gives KNF indentation
for locals (none)). The indentation for globals also applies to struct
member names in local declatations. The indentation of variable names
in multi-line declarations is broken in various ways and this commit
gives some new variations.
indent.1:
Also clarified the description of -di<N>.
nonzero (so that the 1-char indentation given by -di0 is never rendered
by a tab).
Removed garbage commented out code for setting the indentation of variable
names.
worse than useless because it caused things like mangling of
"^int\tfoo" to "int foo" (this for N = 8). This quick fix breaks
the invariant that characters between s_code and e_code have width 1,
but nothing seems to depend on this.
was mangled to "struct foo * bar". There should be an option to control
this, but no space is normal. This finishes fixing the bugs in rev.1.4.
indent(1) still doesn't really understand types in parameter lists. It
thinks keywords inside parentheses are for casts or sizeofs. This works
accidentally for scalar types and this quick fix makes it work similarly
but not so accidentally for struct/union/enum types.
- Factor out common settings and put them in an upper level Makefile.inc.
- Properly use PROG for real programs, not their products.
- Further reduce diffs to i386 versions.
Tested on: sparc64 (panther)
- Now that bsd.prog.mk deals with programs linked with -nostdlib
better, and has a notion of an "internal" program, use PROG
where possible. This has a good impact on the contents of
.depend files and causes programs to be linked with cc(1).
XXX: boot2 couldn't be converted as it's actually two programs.
Tested on: i386, amd64
- Don't put libc.a as a dependency if program is linked with -nostdlib.
- Added INTERNALPROG (by analogy to INTERNALLIB) for programs which are
built only for its side effect and shold not be installed.
the number of typedef-names is not so limited. Same as in rev.1.4.
Added the "const" and "volatile" to the keyword table. Rev.1.4 added
these but they were misclassified so they were not formatted as types.
indent still doesn't really understand them. E.g., it mangles
"char * const *foo" and "char *const *foo". This change mainly stops
it mangling "char const foo" to "char<declaration-indent>const foo".
properly. Of the 3 changes mentioned in the log message for rev.1.4,
the first (implementing -[n]fcb) was correct but didn't touch this
file, the second (no-space-after-sizeof) was not actually done (it is
the default and is controlled by the undcoumented -[n]bs options), and
the third (no-space-after 'struct foo *') was very buggy and was reduced
to wrong comments and other style bugs by backing out the main part
of it in rev.1.6. Rev.1.4 had 2 changes which were not mentioned in
its commit log: expand specials[] so that more than -83 typedef-names
can be specified (this was the one working change in rev.1.4), and add
"const" and "volatile" to specials[] (this was buggy).
hostname rather than an IP. The code was copying the pointer to the
IP address instead of the IP address itself. The bug has existed
ever since ypset was first imported in 1994.

- Ensure that the buffer ends with "\n\0" to avoid special cases
and allow the use of strtol().
- Use strvisx() on each complete line instead of character by
character.

lookup on an IP address from the packet (such as the IP that sent
a TTL exceeded error). If the DNS lookup takes a long time, ^C will
appear to be ineffective since the SIGINT handler just sets a flag
and returns. Work around this by exiting immediately on receipt of
a second SIGINT when DNS lookups are enabled.

the "disappearing subdisks" problem when new subdisks can't be created
due to some errors.
This is in fact an ugly hack, but a more elegant solution would probably
require a redesign of vinum in several places.

mindful of blocking on disk I/O and instead return EBUSY when such
blocking would occur.
Results from the DeBox project indicate that blocking on disk I/O
can slow the performance of a kqueue/poll based webserver. Using
a flag such as SF_NODISKIO and throwing connections that would block
to helper processes/threads helped increase performance.
Currently, only the Flash webserver uses this flag, although it could
probably be applied to thttpd with relative ease.
