Basic Installation
|
||||
==================
|
||||
|
||||
These are generic installation instructions.
|
||||
|
||||
The `configure' shell script attempts to guess correct values for
|
||||
various system-dependent variables used during compilation. It uses
|
||||
those values to create a `Makefile' in each directory of the package.
|
||||
It may also create one or more `.h' files containing system-dependent
|
||||
definitions. Finally, it creates a shell script `config.status' that
|
||||
you can run in the future to recreate the current configuration, and a
|
||||
file `config.log' containing compiler output (useful mainly for
|
||||
debugging `configure').
|
||||
|
||||
It can also use an optional file (typically called `config.cache'
|
||||
and enabled with `--cache-file=config.cache' or simply `-C') that saves
|
||||
the results of its tests to speed up reconfiguring. (Caching is
|
||||
disabled by default to prevent problems with accidental use of stale
|
||||
cache files.)
|
||||
|
||||
If you need to do unusual things to compile the package, please try
|
||||
to figure out how `configure' could check whether to do them, and mail
|
||||
diffs or instructions to the address given in the `README' so they can
|
||||
be considered for the next release. If you are using the cache, and at
|
||||
some point `config.cache' contains results you don't want to keep, you
|
||||
may remove or edit it.
|
||||
|
||||
The file `configure.ac' (or `configure.in') is used to create
|
||||
`configure' by a program called `autoconf'. You only need
|
||||
`configure.ac' if you want to change it or regenerate `configure' using
|
||||
a newer version of `autoconf'.
|
||||
|
||||
The simplest way to compile this package is:
|
||||
|
||||
1. `cd' to the directory containing the package's source code and type
|
||||
`./configure' to configure the package for your system. If you're
|
||||
using `csh' on an old version of System V, you might need to type
|
||||
`sh ./configure' instead to prevent `csh' from trying to execute
|
||||
`configure' itself.
|
||||
|
||||
Running `configure' takes awhile. While running, it prints some
|
||||
messages telling which features it is checking for.
|
||||
|
||||
2. Type `make' to compile the package.
|
||||
|
||||
3. Optionally, type `make check' to run any self-tests that come with
|
||||
the package.
|
||||
|
||||
4. Type `make install' to install the programs and any data files and
|
||||
documentation.
|
||||
|
||||
5. You can remove the program binaries and object files from the
|
||||
source code directory by typing `make clean'. To also remove the
|
||||
files that `configure' created (so you can compile the package for
|
||||
a different kind of computer), type `make distclean'. There is
|
||||
also a `make maintainer-clean' target, but that is intended mainly
|
||||
for the package's developers. If you use it, you may have to get
|
||||
all sorts of other programs in order to regenerate files that came
|
||||
with the distribution.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems require unusual options for compilation or linking that
|
||||
the `configure' script does not know about. Run `./configure --help'
|
||||
for details on some of the pertinent environment variables.
|
||||
|
||||
You can give `configure' initial values for configuration parameters
|
||||
by setting variables in the command line or in the environment. Here
|
||||
is an example:
|
||||
|
||||
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
|
||||
|
||||
*Note Defining Variables::, for more details.
|
||||
|
||||
Compiling For Multiple Architectures
|
||||
====================================
|
||||
|
||||
You can compile the package for more than one kind of computer at the
|
||||
same time, by placing the object files for each architecture in their
|
||||
own directory. To do this, you must use a version of `make' that
|
||||
supports the `VPATH' variable, such as GNU `make'. `cd' to the
|
||||
directory where you want the object files and executables to go and run
|
||||
the `configure' script. `configure' automatically checks for the
|
||||
source code in the directory that `configure' is in and in `..'.
|
||||
|
||||
If you have to use a `make' that does not support the `VPATH'
|
||||
variable, you have to compile the package for one architecture at a
|
||||
time in the source code directory. After you have installed the
|
||||
package for one architecture, use `make distclean' before reconfiguring
|
||||
for another architecture.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, `make install' will install the package's files in
|
||||
`/usr/local/bin', `/usr/local/man', etc. You can specify an
|
||||
installation prefix other than `/usr/local' by giving `configure' the
|
||||
option `--prefix=PATH'.
|
||||
|
||||
You can specify separate installation prefixes for
|
||||
architecture-specific files and architecture-independent files. If you
|
||||
give `configure' the option `--exec-prefix=PATH', the package will use
|
||||
PATH as the prefix for installing programs and libraries.
|
||||
Documentation and other data files will still use the regular prefix.
|
||||
|
||||
In addition, if you use an unusual directory layout you can give
|
||||
options like `--bindir=PATH' to specify different values for particular
|
||||
kinds of files. Run `configure --help' for a list of the directories
|
||||
you can set and what kinds of files go in them.
|
||||
|
||||
If the package supports it, you can cause programs to be installed
|
||||
with an extra prefix or suffix on their names by giving `configure' the
|
||||
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
Some packages pay attention to `--enable-FEATURE' options to
|
||||
`configure', where FEATURE indicates an optional part of the package.
|
||||
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
|
||||
is something like `gnu-as' or `x' (for the X Window System). The
|
||||
`README' should mention any `--enable-' and `--with-' options that the
|
||||
package recognizes.
|
||||
|
||||
For packages that use the X Window System, `configure' can usually
|
||||
find the X include and library files automatically, but if it doesn't,
|
||||
you can use the `configure' options `--x-includes=DIR' and
|
||||
`--x-libraries=DIR' to specify their locations.
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features `configure' cannot figure out
|
||||
automatically, but needs to determine by the type of machine the package
|
||||
will run on. Usually, assuming the package is built to be run on the
|
||||
_same_ architectures, `configure' can figure that out, but if it prints
|
||||
a message saying it cannot guess the machine type, give it the
|
||||
`--build=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as `sun4', or a canonical name which has the form:
|
||||
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
where SYSTEM can have one of these forms:
|
||||
|
||||
OS KERNEL-OS
|
||||
|
||||
See the file `config.sub' for the possible values of each field. If
|
||||
`config.sub' isn't included in this package, then this package doesn't
|
||||
need to know the machine type.
|
||||
|
||||
If you are _building_ compiler tools for cross-compiling, you should
|
||||
use the `--target=TYPE' option to select the type of system they will
|
||||
produce code for.
|
||||
|
||||
If you want to _use_ a cross compiler, that generates code for a
|
||||
platform different from the build platform, you should specify the
|
||||
"host" platform (i.e., that on which the generated programs will
|
||||
eventually be run) with `--host=TYPE'.
|
||||
|
||||
Sharing Defaults
|
||||
================
|
||||
|
||||
If you want to set default values for `configure' scripts to share,
|
||||
you can create a site shell script called `config.site' that gives
|
||||
default values for variables like `CC', `cache_file', and `prefix'.
|
||||
`configure' looks for `PREFIX/share/config.site' if it exists, then
|
||||
`PREFIX/etc/config.site' if it exists. Or, you can set the
|
||||
`CONFIG_SITE' environment variable to the location of the site script.
|
||||
A warning: not all `configure' scripts look for a site script.
|
||||
|
||||
Defining Variables
|
||||
==================
|
||||
|
||||
Variables not defined in a site shell script can be set in the
|
||||
environment passed to `configure'. However, some packages may run
|
||||
configure again during the build, and the customized values of these
|
||||
variables may be lost. In order to avoid this problem, you should set
|
||||
them in the `configure' command line, using `VAR=value'. For example:
|
||||
|
||||
./configure CC=/usr/local2/bin/gcc
|
||||
|
||||
will cause the specified gcc to be used as the C compiler (unless it is
|
||||
overridden in the site shell script).
|
||||
|
||||
`configure' Invocation
|
||||
======================
|
||||
|
||||
`configure' recognizes the following options to control how it
|
||||
operates.
|
||||
|
||||
`--help'
|
||||
`-h'
|
||||
Print a summary of the options to `configure', and exit.
|
||||
|
||||
`--version'
|
||||
`-V'
|
||||
Print the version of Autoconf used to generate the `configure'
|
||||
script, and exit.
|
||||
|
||||
`--cache-file=FILE'
|
||||
Enable the cache: use and save the results of the tests in FILE,
|
||||
traditionally `config.cache'. FILE defaults to `/dev/null' to
|
||||
disable caching.
|
||||
|
||||
`--config-cache'
|
||||
`-C'
|
||||
Alias for `--cache-file=config.cache'.
|
||||
|
||||
`--quiet'
|
||||
`--silent'
|
||||
`-q'
|
||||
Do not print messages saying which checks are being made. To
|
||||
suppress all normal output, redirect it to `/dev/null' (any error
|
||||
messages will still be shown).
|
||||
|
||||
`--srcdir=DIR'
|
||||
Look for the package's source code in directory DIR. Usually
|
||||
`configure' can determine that directory automatically.
|
||||
|
||||
`configure' also accepts some other, not widely useful, options. Run
|
||||
`configure --help' for more details.

Snappy, a fast compressor/decompressor.
|
||||
|
||||
|
||||
Introduction
|
||||
============
|
||||
|
||||
Snappy is a compression/decompression library. It does not aim for maximum
|
||||
compression, or compatibility with any other compression library; instead,
|
||||
it aims for very high speeds and reasonable compression. For instance,
|
||||
compared to the fastest mode of zlib, Snappy is an order of magnitude faster
|
||||
for most inputs, but the resulting compressed files are anywhere from 20% to
|
||||
100% bigger. (For more information, see "Performance", below.)
|
||||
|
||||
Snappy has the following properties:
|
||||
|
||||
* Fast: Compression speeds at 250 MB/sec and beyond, with no assembler code.
|
||||
See "Performance" below.
|
||||
* Stable: Over the last few years, Snappy has compressed and decompressed
|
||||
petabytes of data in Google's production environment. The Snappy bitstream
|
||||
format is stable and will not change between versions.
|
||||
* Robust: The Snappy decompressor is designed no to crash in the face of
|
||||
corrupted or malicious input.
|
||||
* Free and open source software: Snappy is licensed under the Apache license,
|
||||
version 2.0. For more information, see the included COPYING file.
|
||||
|
||||
Snappy has previously been called "Zippy" in some Google presentations
|
||||
and the like.
|
||||
|
||||
|
||||
Performance
|
||||
===========
|
||||
|
||||
Snappy is intended to be fast. On a single core of a Core i7 processor
|
||||
in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at
|
||||
about 500 MB/sec or more. (These numbers are for the slowest inputs in our
|
||||
benchmark suite; others are much faster.) In our tests, Snappy usually
|
||||
is faster than algorithms in the same class (e.g. LZO, LZF, FastLZ, QuickLZ,
|
||||
etc.) while achieving comparable compression ratios.
|
||||
|
||||
Typical compression ratios (based on the benchmark suite) are about 1.5-1.7x
|
||||
for plain text, about 2-4x for HTML, and of course 1.0x for JPEGs, PNGs and
|
||||
other already-compressed data. Similar numbers for zlib in its fastest mode
|
||||
are 2.6-2.8x, 3-7x and 1.0x, respectively. More sophisticated algorithms are
|
||||
capable of achieving yet higher compression rates, although usually at the
|
||||
expense of speed. Of course, compression ratio will vary significantly with
|
||||
the input.
|
||||
|
||||
Although Snappy should be fairly portable, it is primarily optimized
|
||||
for 64-bit x86-compatible processors, and may run slower in other environments.
|
||||
In particular:
|
||||
|
||||
- Snappy uses 64-bit operations in several places to process more data at
|
||||
once than would otherwise be possible.
|
||||
- Snappy assumes unaligned 32- and 64-bit loads and stores are cheap.
|
||||
On some platforms, these must be emulated with single-byte loads
|
||||
and stores, which is much slower.
|
||||
- Snappy assumes little-endian throughout, and needs to byte-swap data in
|
||||
several places if running on a big-endian platform.
|
||||
|
||||
Experience has shown that even heavily tuned code can be improved.
|
||||
Performance optimizations, whether for 64-bit x86 or other platforms,
|
||||
are of course most welcome; see "Contact", below.
|
||||
|
||||
|
||||
Usage
|
||||
=====
|
||||
|
||||
Note that Snappy, both the implementation and the interface,
|
||||
is written in C++.
|
||||
|
||||
To use Snappy from your own program, include the file "snappy.h" from
|
||||
your calling file, and link against the compiled library.
|
||||
|
||||
There are many ways to call Snappy, but the simplest possible is
|
||||
|
||||
snappy::Compress(input, &output);
|
||||
|
||||
and similarly
|
||||
|
||||
snappy::Uncompress(input, &output);
|
||||
|
||||
where "input" and "output" are both instances of std::string.
|
||||
|
||||
There are other interfaces that are more flexible in various ways, including
|
||||
support for custom (non-array) input sources. See the header file for more
|
||||
information.
|
||||
|
||||
|
||||
Tests and benchmarks
|
||||
====================
|
||||
|
||||
When you compile Snappy, snappy_unittest is compiled in addition to the
|
||||
library itself. You do not need it to use the compressor from your own library,
|
||||
but it contains several useful components for Snappy development.
|
||||
|
||||
First of all, it contains unit tests, verifying correctness on your machine in
|
||||
various scenarios. If you want to change or optimize Snappy, please run the
|
||||
tests to verify you have not broken anything. Note that if you have the
|
||||
Google Test library installed, unit test behavior (especially failures) will be
|
||||
significantly more user-friendly. You can find Google Test at
|
||||
|
||||
http://code.google.com/p/googletest/
|
||||
|
||||
You probably also want the gflags library for handling of command-line flags;
|
||||
you can find it at
|
||||
|
||||
http://code.google.com/p/google-gflags/
|
||||
|
||||
In addition to the unit tests, snappy contains microbenchmarks used to
|
||||
tune compression and decompression performance. These are automatically run
|
||||
before the unit tests, but you can disable them using the flag
|
||||
--run_microbenchmarks=false if you have gflags installed (otherwise you will
|
||||
need to edit the source).
|
||||
|
||||
Finally, snappy can benchmark Snappy against a few other compression libraries
|
||||
(zlib, LZO, LZF, FastLZ and QuickLZ), if they were detected at configure time.
|
||||
To benchmark using a given file, give the compression algorithm you want to test
|
||||
Snappy against (e.g. --zlib) and then a list of one or more file names on the
|
||||
command line. The testdata/ directory contains the files used by the
|
||||
microbenchmark, which should provide a reasonably balanced starting point for
|
||||
benchmarking. (Note that baddata[1-3].snappy are not intended as benchmarks; they
|
||||
are used to verify correctness in the presence of corrupted data in the unit
|
||||
test.)

# using a macro with the same name in our local m4/libtool.m4 it'll
|

# pull the old libtool.m4 in (it doesn't see our shiny new m4_define

# and doesn't know about Autoconf macros at all.)
|

#
|

# So we provide this file, which has a silly filename so it's always

# included after everything else. This provides aclocal with the
|

# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything

# because those macros already exist, or will be overwritten later.
|

# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
|

#
|

# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

# Yes, that means every name once taken will need to remain here until
|

# we give up compatibility with versions before 1.7, at which point
|

# we need to keep only those names which we still refer to.

.SH DESCRIPTION
|
||||
This manual page
|
||||
documents the GNU version of
|
||||
.BR xargs .
|
||||
.B xargs
|
||||
reads arguments from the standard input, delimited by blanks (which can be
|
||||
protected with double or single quotes or a backslash) or newlines,
|
||||
and executes the
|
||||
.I command
|
||||
(default is /bin/echo) one or more times with any
|
||||
.I initial-arguments
|
||||
followed by arguments read from standard input. Blank lines on the
|
||||
standard input are ignored.
|
||||
.P
|
||||
.B xargs
|
||||
exits with the following status:
|
||||
.nf
|
||||
0 if it succeeds
|
||||
123 if any invocation of the command exited with status 1-125
|
||||
124 if the command exited with status 255
|
||||
125 if the command is killed by a signal
|
||||
126 if the command cannot be run
|
||||
127 if the command is not found
|
||||
1 if some other error occurred.
|
||||
.fi
|
||||
.SS OPTIONS
|
||||
.TP
|
||||
.I "\-\-null, \-0"
|
||||
Input filenames are terminated by a null character instead of by
|
||||
whitespace, and the quotes and backslash are not special (every
|
||||
character is taken literally). Disables the end of file string, which
|
||||
is treated like any other argument. Useful when arguments might
|
||||
contain white space, quote marks, or backslashes. The GNU find
|
||||
\-print0 option produces input suitable for this mode.
|
||||
.TP
|
||||
.I "\-\-eof[=eof-str], \-e[eof-str]"
|
||||
Set the end of file string to \fIeof-str\fR. If the end of file
|
||||
string occurs as a line of input, the rest of the input is ignored.
|
||||
If \fIeof-str\fR is omitted, there is no end of file string. If this
|
||||
option is not given, the end of file string defaults to "_".
|
||||
.TP
|
||||
.I "\-\-help"
|
||||
Print a summary of the options to
|
||||
.B xargs
|
||||
and exit.
|
||||
.TP
|
||||
.I "\-\-replace[=replace-str], \-i[replace-str]"
|
||||
Replace occurences of \fIreplace-str\fR in the initial arguments with
|
||||
names read from standard input.
|
||||
Also, unquoted blanks do not terminate arguments.
|
||||
If \fIreplace-str\fR is omitted, it
|
||||
defaults to "{}" (like for `find \-exec'). Implies \fI\-x\fP and
|
||||
\fI\-l 1\fP.
|
||||
.TP
|
||||
.I "\-\-max-lines[=max-lines], -l[max-lines]"
|
||||
Use at most \fImax-lines\fR nonblank input lines per command line;
|
||||
\fImax-lines\fR defaults to 1 if omitted. Trailing blanks cause an
|
||||
input line to be logically continued on the next input line. Implies
|
||||
\fI\-x\fR.
|
||||
.TP
|
||||
.I "\-\-max-args=max-args, \-n max-args"
|
||||
Use at most \fImax-args\fR arguments per command line. Fewer than
|
||||
\fImax-args\fR arguments will be used if the size (see the \-s option)
|
||||
is exceeded, unless the \-x option is given, in which case \fBxargs\fR
|
||||
will exit.
|
||||
.TP
|
||||
.I "\-\-interactive, \-p"
|
||||
Prompt the user about whether to run each command line and read a line
|
||||
from the terminal. Only run the command line if the response starts
|
||||
with `y' or `Y'. Implies \fI\-t\fR.
|
||||
.TP
|
||||
.I "\-\-no-run-if-empty, \-r"
|
||||
If the standard input does not contain any nonblanks, do not run the
|
||||
command. Normally, the command is run once even if there is no input.
|
||||
.TP
|
||||
.I "\-\-max-chars=max-chars, \-s max-chars"
|
||||
Use at most \fImax-chars\fR characters per command line, including the
|
||||
command and initial arguments and the terminating nulls at the ends of
|
||||
the argument strings. The default is as large as possible, up to 20k
|
||||
characters.
|
||||
.TP
|
||||
.I "\-\-verbose, \-t"
|
||||
Print the command line on the standard error output before executing
|
||||
it.
|
||||
.TP
|
||||
.I "\-\-version"
|
||||
Print the version number of
|
||||
.B xargs
|
||||
and exit.
|
||||
.TP
|
||||
.I "\-\-exit, \-x"
|
||||
Exit if the size (see the \fI\-s\fR option) is exceeded.
|
||||
.TP
|
||||
.I "\-\-max-procs=max-procs, \-P max-procs"
|
||||
Run up to \fImax-procs\fR processes at a time; the default is 1. If
|
||||
\fImax-procs\fR is 0, \fBxargs\fR will run as many processes as
|
||||
possible at a time. Use the \fI\-n\fR option with \fI\-P\fR;
|
||||
otherwise chances are that only one exec will be done.

||||
