Basic Installation
==================
@ -74,51 +76,65 @@ is not the usual GNU Autoconf script.
<options> can be one of the following:
<options> can be one of the following:
--prefix=<val> The installation prefix.
This is set to /usr by default. However alternate
prefix needs to eb used during packaging.
--prefix=<val> The installation prefix (default: /usr).
--enable-debug Enable debug mode compilation.
This reduces the compiler optimization level to
basic and taks out all the loop optimization flags.
This is primarily to aid debugging.
--enable-debug Enable debug mode compilation (default: disabled).
--disable-allocator Disable use of internal memory allocator mechanism.
The internal allocator can be totally disabled by
setting this build time flag. It is also possible
to dynamically disable the allocator by setting the
following env variable:
ALLOCATOR_BYPASS=1
--disable-allocator Disable use of internal memory allocator mechanism (default: enabled).
--enable-debug-stats Enable printing of some verbose debug info.
This at present shows some info related to Dedupe
efficiency.
--enable-debug-stats Enable printing of some verbose debug info (default: disabled).
--with-openssl=<path to OpenSSL installation tree> (Default: System)
This defaults to the system's OpenSSL library. You can use this option
if you want to use an alternate OpenSSL installation.
--with-libbsc=<path_to_libbsc_source>
Enable support for libbsc (See: libbsc.com). Full
path to the libbsc source tree must be provided. It
links the library statically.
--with-zlib=<path to zlib installation tree> (Default: System)
Enable building against an alternate Zlib installation.
--with-bzlib=<path to Bzip2 library installation tree> (Default: System)
Enable building against an alternate Bzip2 and library installation.
Enable building against an alternate Bzip2 and library
installation.
--with-external-libbsc=<path to libbsc source tree>
Enable building with exernal libbsc sources. Can be used to link with
ASLv2 libbsc when using MPLv2 licensed sources.
--no-sse-detect Do not try to detect the CPU's SSE capability. This
mode will simply use SSE2 as the fallback default.
Using SSE4 and later improves performance significantly.
--wavpack-dir=<path to WavPack source tree>
Points to the directory containing the WavPack sources. This option
must be specified if --disable-wavpack is not provided.
--use-key256 Use 256-bit encryption keys. Default key length is
128-bit.
--disable-wavpack Disables the WavPack filter.
--help Display the help message.
--no-sse-detect Do NOT attempt to probe the system's SSE capability for build flags.
Implies '--no-avx-detect' below.
Steps for building with libbsc support
======================================
1) Download libbsc source from: http://libbsc.com/ . Click on the
"Download TAR Ball" button. Downloading the 3.1.0 release from the
Github project download page will Not work.
--no-avx-detect Do NOT attempt to probe the system's AVX capability for build flags.
2) Extract the gzippped tarball. It will create a directory for example:
IlyaGrebnov-libbsc-0b12f29
--no-1.3-archive-compat Disable compatibility with compressed archives created with Pcompress
version 1.3 (default: retain compatibility). Hash formats changed from
version 1.3 to 1.4 so this option is required if files created using
1.3 need to be decompressed by version 1.4 onwards.
3) Now cd into the pcompress directory and execute the config script
with the full path to the libbsc source directory. For example:
--limit-key128 Limit key length to 128-bit encryption keys. Otherwise the default is to
use 256-bit keys changeable at runtime via the '-k <keylen>' option.
./config --with-libbsc=/full/path/to/IlyaGrebnov-libbsc-0b12f29
--help Display this help message.
4) Now run make in the pcompress directory. This will also run make in
the libbsc source directory to build it.
Additional compilation flags can be passed to make like this:
5) Additional compilation flags can be passed to make like this:
make EXTRA_CPPFLAGS=<...> EXTRA_LDFLAGS=<...>

Pcompress is an archiver that also does compression and decompression in
parallel by splitting input data into chunks. It has a modular structure
and includes support for multiple algorithms like LZMA, Bzip2, PPMD, etc,
with SKEIN/SHA checksums for data integrity. Compression algorithms are
selected based on the file type to maximize compression gains using a file
and data anaylis based adaptive technique. It also includes various data
transformation filters to improve compression.
It also implements Variable Block Deduplication and Delta Compression
features based on a Polynomial Fingerprinting scheme. Delta Compression
is done via the widely popular bsdiff algorithm. Similarity is detected
using a technique based on MinHashing. Deduplication metadata is also
compressed to reduce overheads. In addition to all these it can internally
split chunks at file and rabin boundaries to help Dedupe and compression.

LICENSING
=========
Pcompress is dual licensed with LGPLv3 and MPLv2 sources. The main git
repository is LGPL licensed. A separate tarball of the sources with
MPLv2 license is made available as a download. This is updated
periodically. Since Pcompress also integrates a bunch of third-party
software a few features may be missing in the MPLv2 licensed version
because of the upstream software being LGPL licensed originally.
NOTE: This utility is Not an archiver. It compresses only single files or
datastreams. To archive use something else like tar, cpio or pax.

Standard Usage
==============
Standard usage consists of a few common options to control basic behavior. A variety of
parameters including global deduplication are automatically set based on the compression
level.
Usage
=====
Archiving
---------
pcompress -a [-v] [-l <compress level>] [-s <chunk size>] [-c <algorithm>]
[<file1> <directory1> <file2> ...] [-t <number>] [-S <chunk checksum>]
<archive filename or '-'>
To compress a file:
pcompress -c <algorithm> [-l <compress level>] [-s <chunk size>] <file> [-]
Archives a given set of files and/or directories into a compressed PAX archive. The
PAX datastream is encoded into a custom format compressed file that can only be
handled by Pcompress.
Where <algorithm> can be the folowing:
lzfx - Very fast and small algorithm based on LZF.
lz4 - Ultra fast, high-throughput algorithm reaching RAM B/W at level1.
zlib - The base Zlib format compression (not Gzip).
lzma - The LZMA (Lempel-Ziv Markov) algorithm from 7Zip.
lzmaMt - Multithreaded version of LZMA. This is a faster version but
uses more memory for the dictionary. Thread count is balanced
between chunk processing threads and algorithm threads.
bzip2 - Bzip2 Algorithm from libbzip2.
ppmd - The PPMd algorithm excellent for textual data. PPMd requires
at least 64MB X CPUs more memory than the other modes.
-a Enables archive mode where pathnames specified in the command line are
archived using LibArchive and then compressed.
libbsc - A Block Sorting Compressor using the Burrows Wheeler Transform
like Bzip2 but runs faster and gives better compression than
Bzip2 (See: libbsc.com).
-l <compress level>
Select a compression level from 1 (least compression, fastest) to 14
(ultra compression, slow). Default: 6
adapt - Adaptive mode where ppmd or bzip2 will be used per chunk,
depending on heuristics. If at least 50% of the input data is
7-bit text then PPMd will be used otherwise Bzip2.
adapt2 - Adaptive mode which includes ppmd and lzma. If at least 80% of
the input data is 7-bit text then PPMd will be used otherwise
LZMA. It has significantly more memory usage than adapt.
none - No compression. This is only meaningful with -D and -E so Dedupe
can be done for post-processing with an external utility.
-s <chunk size>
Archive data is split into chunks that are processed in parallel. This value
specifies the maximum chunk size. Blocks may be smaller than this. Values
can be in bytes or <number><suffix> format where suffix can be k - KB, m - MB,
g - GB. Default: 8m
Larger chunks can produce better compression at the cost of memory.
<chunk_size> - This can be in bytes or can use the following suffixes:
g - Gigabyte, m - Megabyte, k - Kilobyte.
Larger chunks produce better compression at the cost of memory.
In case of Global Deduplication (see below) this chunk size is
just a hint and may get automatically adjusted.
<compress_level> - Can be a number from 0 meaning minimum and 14 meaning
maximum compression.
'-' - If '-' is given as the final argument then it specifies that
compressed output should go to stdout.
-c <algorithm>
Specifies the compression algorithm to use. Default algorithm when archiving
is adapt2 (Second Adaptive Mode). This is the ideal mode for archiving giving
best compression gains. However adapt (Adaptive Mode) can be used which is a
little faster but give lower compression gains.
Other algorithms can be used if all the files are of the same known type. For
example ppmd (slow) or libbsc (fast) can be used if all the files only have
ASCII text. See section "Compression Algorithms" for details.
NOTE: The option "libbsc" uses Ilya Grebnov's block sorting compression library
from http://libbsc.com/ . It is only available if pcompress in built with
that library. See INSTALL file for details.
To decompress a file compressed using above command:
pcompress -d <compressed file> <target file>
<compressed file> can be '-' to indicate reading from stdin while write goes
to <target file>
-v Enables verbose mode where each file/directory is printed as it is processed.
To operate as a full pipe, read from stdin and write to stdout:
pcompress -p ...
-t <number>
Sets the number of threads that Pcompress can use. Pcompress automatically
uses thread count = core count. However with larger chunk size (-s option)
and/or ultra compression levels, large amounts of memory can be used. In this
case thread count can be reduced to reduce memory consumption.
-S <chunk checksum>
Specify then chunk checksum to use. Default: BLAKE256. The following checksums
are available:
CRC64 - Extremely Fast 64-bit CRC from LZMA SDK.
SHA256 - SHA512/256 version of Intel's optimized (SSE,AVX) SHA2 for x86.
SHA512 - SHA512 version of Intel's optimized (SSE,AVX) SHA2 for x86.
KECCAK256 - Official 256-bit NIST SHA3 optimized implementation.
KECCAK512 - Official 512-bit NIST SHA3 optimized implementation.
BLAKE256 - Very fast 256-bit BLAKE2, derived from the NIST SHA3
runner-up BLAKE.
BLAKE512 - Very fast 256-bit BLAKE2, derived from the NIST SHA3
runner-up BLAKE.
The fastest checksum is the BLAKE2 family.
-T
Disable Metadata Streams. Pathname metadata is normally packed into separate
chunks distinct from file data. With this option this behavior is disabled.
<archive filename>
Pathname of the resulting archive. A '.pz' extension is automatically added
if not already present. This can also be specified as '-' in order to send
the compressed archive stream to stdout.
Single File Compression
-----------------------
pcompress -c <algorithm> [-l <compress level>] [-s <chunk size>] [-p] [<file>]
[-t <number>] [-S <chunk checksum>] [<target file or '-'>]
Takes a single file as input and produces a compressed file. Archiving is not performed.
This can also work in streaming mode.
-c <algorithm>
See above. Also see section "Compression Algorithms" for details.
-l <compress level>
-s <chunk size>
-t <number>
-S <chunk checksum>
See above.
Note: In singe file compression mode with adapt2 or adapt algorithm, larger
chunks may not produce better compression. Smaller chunks can result
in better data analysis here.
-p Make Pcompress work in streaming mode. Data is ingested via stdin
compressed and output via stdout. No filenames are used.
<target file>
Pathname of the compressed file to be created. This can be '-' to send the
compressed data to stdout.
Decompression and Archive extraction
------------------------------------
pcompress -d <compressed file or '-'> [-m] [-K] [-i] [<target file or directory>]
-m Enable restoring *all* permissions, ACLs, Extended Attributes etc.
Equivalent to the '-p' option in tar. Ownership is only extracted if run as
root user.
-K Do not overwrite newer files.
-i Only list contents of the archive, do not extract.
-m and -K are only meaningful if the compressed file is an archive. For single file
compressed mode these options are ignored.
<compressed file>
Specifies the compressed file or archive. This can be '-' to indicate reading
from stdin while write goes to <target file>
<target file or directory>
This can be a filename or a directory depending on how the archive was created.
If single file compression was used then this can be the name of the target
file that will hold the uncompressed data.
If this is omitted then an output file is created by appending '.out' to the
compressed filename.
If Archiving was done then this should be the name of a directory into which
extracted files are restored. The directory is created if it does not exist.
If this is omitted the files are extracted into the current directory.
Compression Algorithms
======================
lzfx - Fast, average compression. At high compression levels this can be faster
than LZ4.
Effective Levels: 1 - 5
lz4 - Very Fast, sometimes better compression than LZFX.
Effective Levels: 1 - 3
zlib - Fast, better compression.
Effective Levels: 1 - 9
bzip2 - Slow, much better compression than Zlib.
Effective Levels: 1 - 9
lzma - Very slow. Extreme compression. Recommended: Use lzmaMt variant mentioned
below.
Effective Levels: 1 - 14
Till level 9 it is standard LZMA parameters. Levels 10 - 12 use
more memory and higher match iterations so are slower. Levels
13 and 14 use larger dictionaries upto 256MB and really suck up
RAM. Use these levels only if you have at the minimum 4GB RAM on
your system.
lzmaMt - This is the multithreaded variant of lzma and typically runs faster.
However in a few cases this can produce slightly lesser compression
gain.
libbsc - This is a new block-sorting compressor having much better effectiveness
and performance over a variety of data types as compared to Bzip2.
NOTE: In the LGPL licensed version libbsc is an integral part of Pcompress.
When building MPLv2 licensed sources, the libbsc sources must be
downloaded separately and linked in. This is described in the INSTALL file.
PPMD - Slow. Extreme compression for Text, average compression for binary.
In addition PPMD decompression time is also high for large chunks.
This requires lots of RAM similar to LZMA. PPMd requires
at least 64MB X core-count more memory than the other modes.
Effective Levels: 1 - 14.
Adapt - Synthetic mode with text/binary detection. For pure text data PPMD is
used otherwise Bzip2 is selected per chunk.
Effective Levels: 1 - 14
Adapt2 - Slower synthetic mode. For pure text data PPMD is otherwise LZMA is
applied. Can give very good compression ratio when splitting file
into multiple chunks.
Effective Levels: 1 - 14
Since both LZMA and PPMD are used together memory requirements are
large especially if you are also using extreme levels above 10. For
example with 100MB chunks, Level 14, 2 threads and with or without
dedupe, it uses upto 2.5GB physical RAM (RSS).
none - No compression. This is only meaningful with -G or -D. So Dedupe
can be done for post-processing with an external utility.
Enabled features based on Compression Level
===========================================
1 to 3 - No features, just compression and archiving, if needed.
4 - Global Deduplication with avg block size of 8KB.
5 - Global Dedup block size 8KB, Adaptive Delta Encoding.
6 to 8 - Global Dedup block size reduced to 4KB, Adaptive Delta Encoding.
9 - Global Dedup block size reduced to 2KB, Adaptive Delta Encoding, Dispack.
10 - Global Dedup block size 2KB, Adaptive Delta Encoding with extra rounds, Dispack,
LZP Preprocessing
10 - 14 - Global Dedup block size 2KB, Adaptive Delta Encoding with extra rounds, Dispack,
LZP Preprocessing, PackJPG filter for Jpegs.
NOTE: - LZP Preprocessing and PackJPG are not available in the MPLv2 licensed version.
Encryption
==========
Pcompress supports encryption and authentication in both archive and single-file
compresion modes. Encryption options are discussed below.
NOTE: When using pipe-mode via -p the only way to provide a password is to use '-w'.
See below.
-e <ALGO>
Encrypt chunks using the given encryption algorithm. The algo parameter
can be one of AES or SALSA20. Both are used in CTR stream encryption
mode.
The password can be prompted from the user or read from a file. Unique
keys are generated every time pcompress is run even when giving the same
password. Of course enough info is stored in the compresse file so that
the key used for the file can be re-created given the correct password.
Default key length if 256 bits but can be reduced to 128 bits using the
'-k' option.
The Scrypt algorithm from Tarsnap is used
(See: http://www.tarsnap.com/scrypt.html) for generating keys from
passwords. The CTR mode AES mechanism from Tarsnap is also utilized.
-w <pathname>
Provide a file which contains the encryption password. This file must
be readable and writable since it is zeroed out after the password is
read.
-k <key length>
Specify the key length. Can be 16 for 128 bit keys or 32 for 256 bit
keys. Default value is 32 for 256 bit keys.
Advanced usage
==============
A variety of advanced options are provided if one wishes fine grained control
as opposed to automatic settings. If advanced options are used then auto-setting
of parameters get disabled. The various advanced options are discussed below.
Chunk-level Deduplication
-------------------------
Attempt Polynomial fingerprinting based deduplication on a per-chunk basis:
Attempt Rabin fingerprinting based deduplication on chunks:
pcompress -D ...
pcompress -D -r ... - Do NOT split chunks at a rabin boundary. Default
is to split.
Perform Delta Encoding in addition to Identical Dedup:
pcompress -E ... - This also implies '-D'. This performs Delta Compression
@ -309,154 +121,203 @@ Advanced usage
effect greater final compression ratio at the cost of
higher processing overhead.
-F Perform Fixed Block Deduplication. This is faster than fingerprinting
based content-aware deduplication in some cases. However this is mostly
usable for disk dumps especially virtual machine images. This generally
gives lower dedupe ratio than content-aware dedupe (-D) and does not
support delta compression.
Number of threads can optionally be specified: -t <1 - 256 count>
Other flags:
'-L' - Enable LZP pre-compression. This improves compression ratio of all
algorithms with some extra CPU and very low RAM overhead. Using
delta encoding in conjunction with this may not always be beneficial.
However Adaptive Delta Encoding is beneficial along with this.
Global Deduplication
--------------------
-G This flag enables Global Deduplication. This makes pcompress maintain an
in-memory index to lookup cryptographic block hashes for duplicates. Once
a duplicate is found it is replaced with a reference to the original block.
This allows detecting and eliminating duplicate blocks across the entire
dataset. In contrast using only '-D' or '-F' flags does deduplication only
within the chunk but uses less memory and is much faster than Global Dedupe.
'-P' - Enable Adaptive Delta Encoding. It can improve compresion ratio further
for data containing tables of numerical values especially if those are
in an arithmetic series. In this implementation basic Delta Encoding is
combined with Run-Length encoding and Matrix transpose
NOTE - Both -L and -P can be used together to give maximum benefit on most
datasets.
The '-G' flag can be combined with either '-D' or '-F' flags to indicate
rabin chunking or fixed chunking respectively. If these flags are not
specified then the default is to assume rabin chunking via '-D'.
All other Dedupe flags have the same meanings in this context.
'-S' <cksum>
- Specify chunk checksum to use:
Delta Encoding is not supported with Global Deduplication at this time. The
in-memory hashtable index can use upto 75% of free RAM depending on the size
of the dataset. In Pipe mode the index will always use 75% of free RAM since
the dataset size is not known. This is the simple full block index mode. If
the available RAM is not enough to hold all block checksums then older block
entries are discarded automatically from the matching hash slots.
CRC64 - Extremely Fast 64-bit CRC from LZMA SDK.
SHA256 - SHA512/256 version of Intel's optimized (SSE,AVX) SHA2 for x86.
SHA512 - SHA512 version of Intel's optimized (SSE,AVX) SHA2 for x86.
KECCAK256 - Official 256-bit NIST SHA3 optimized implementation.
KECCAK512 - Official 512-bit NIST SHA3 optimized implementation.
BLAKE256 - Very fast 256-bit BLAKE2, derived from the NIST SHA3
runner-up BLAKE.
BLAKE512 - Very fast 256-bit BLAKE2, derived from the NIST SHA3
runner-up BLAKE.
If pipe mode is not used and the given dataset is a file then Pcompress
checks whether the index size will exceed three times of 75% of the available
free RAM. In such a case it automatically switches to a Segmented Deduplication
mode. Here data is first split into blocks as above. Then upto 2048 blocks are
grouped together to form a larger segment. The individual block hashes for a
segment are stored on a tempfile on disk. A few min-values hashes are then
computed from the block hashes of the segment which are then loaded into the
index. These hashes are used to detect segments that are approximately similar
to each other. Once found the block hashes of the matching segments are loaded
from the temp file and actual deduplication is performed. This allows the
in-memory index size to be approximately 0.0025% of the total dataset size and
requires very few disk reads for every 2048 blocks processed.
'-F' - Perform Fixed Block Deduplication. This is faster than fingerprinting
based content-aware deduplication in some cases. However this is mostly
usable for disk dumps especially virtual machine images. This generally
gives lower dedupe ratio than content-aware dedupe (-D) and does not
support delta compression.
In pipe mode Global Deduplication always uses a segmented similarity based
index. It allows efficient network transfer of large data.
'-B' <1..5>
- Specify an average Dedupe block size. 1 - 4K, 2 - 8K ... 5 - 64K.
'-M' - Display memory allocator statistics
'-C' - Display compression statistics
-B <0..5>
Specify an average Dedupe block size. 0 - 2K, 1 - 4K, 2 - 8K ... 5 - 64K.
Default deduplication block size is 4KB for Global Deduplication and 2KB
otherwise.
-B 0
This uses blocks as small as 2KB for deduplication. This option can be
used for datasets of a few GBs to a few hundred TBs in size depending on
available RAM.
Global Deduplication:
'-G' - This flag enables Global Deduplication. This makes pcompress maintain an
in-memory index to lookup cryptographic block hashes for duplicates. Once
a duplicate is found it is replaced with a reference to the original block.
This allows detecting and eliminating duplicate blocks across the entire
dataset. In contrast using only '-D' or '-F' flags does deduplication only
within the chunk but uses less memory and is much faster than Global Dedupe.
-L Enable LZP pre-compression. This improves compression ratio of all
algorithms with some extra CPU and very low RAM overhead. Using
delta encoding in conjunction with this may not always be beneficial.
However Adaptive Delta Encoding is beneficial along with this.
The '-G' flag can be combined with either '-D' or '-F' flags to indicate
rabin chunking or fixed chunking respectively. If these flags are not
specified then the default is to assume rabin chunking via '-D'.
All other Dedupe flags have the same meanings in this context.
-P Enable Adaptive Delta Encoding. It can improve compresion ratio further
for data containing tables of numerical values especially if those are
in an arithmetic series. In this implementation basic Delta Encoding is
combined with Run-Length encoding and Matrix transpose
NOTE - Both -L and -P can be used together to give maximum benefit on most
datasets.
Delta Encoding is not supported with Global Deduplication at this time. The
in-memory hashtable index can use upto 75% of free RAM depending on the size
of the dataset. In Pipe mode the index will always use 75% of free RAM since
the dataset size is not known. This is the simple full block index mode. If
the available RAM is not enough to hold all block checksums then older block
entries are discarded automatically from the matching hash slots.
-x Perform Dispack Encoding. This is useful to translate x86 call and jmp
relative offsets to absolute values which compress better. The given
chunk is split into 32KB blocks and some heuristics are used per block
to identify whether it represents x86 instruction stream or not. This
works only when archiving.

In pipe mode Global Deduplication always uses a segmented similarity based
index. It allows efficient network transfer of large data.
-j Enable PackJPG processing for Jpeg files. This works only when archiving.
Encryption flags:
'-e <ALGO>'
Encrypt chunks using the given encryption algorithm. The algo parameter
can be one of AES or SALSA20. Both are used in CTR stream encryption
mode.
The password can be prompted from the user or read from a file. Unique
keys are generated every time pcompress is run even when giving the same
password. Of course enough info is stored in the compresse file so that
the key used for the file can be re-created given the correct password.
-M Display memory allocator statistics.
-C Display compression statistics.
-CC Display compression statistics and print the offset and length of each
variable length dedupe block if variable block deduplication is being
used. This has no effect for fixed block deduplication.
Default key length if 256 bits but can be reduced to 128 bits using the
'-k' option.
The Scrypt algorithm from Tarsnap is used
(See: http://www.tarsnap.com/scrypt.html) for generating keys from
passwords. The CTR mode AES mechanism from Tarsnap is also utilized.
'-w <pathname>'
Provide a file which contains the encryption password. This file must
be readable and writable since it is zeroed out after the password is
read.
'-k <key length>'
Specify the key length. Can be 16 for 128 bit keys or 32 for 256 bit
keys. Default value is 32 for 256 bit keys.
NOTE: When using pipe-mode via -p the only way to provide a password is to use '-w'.
Environment Variables
=====================
Set ALLOCATOR_BYPASS=1 in the environment to avoid using the the built-in
allocator. Due to the the way it rounds up an allocation request to the nearest
slab the built-in allocator can allocate extra unused memory. In addition you
may want to use a different allocator in your environment.

The variable PCOMPRESS_CACHE_DIR can point to a directory where some temporary
files relating to the Global Deduplication process can be stored. This for example
can be a directory on a Solid State Drive to speed up Global Deduplication. The
space used in this directory is proportional to the size of the dataset being
processed and is slightly more than 8KB for every 1MB of data.

Even though SKEIN is not supported as a chunk checksum (not deemed necessary
because BLAKE2 is available) it can be used as a dedupe block checksum. One may
ask why? The reasoning is we depend on hashes to find duplicate blocks. Now SHA256
is the default because it is known to be robust and unbroken till date. Proven as
yet in the field. However one may want a faster alternative so we have choices
from the NIST SHA3 finalists in the form of SKEIN and BLAKE which are neck to
neck with SKEIN getting an edge. SKEIN and BLAKE have seen extensive cryptanalysis
in the intervening years and are unbroken with only marginal theoretical issues
determined. BLAKE2 is a derivative of BLAKE and is tremendously fast but has not
seen much specific cryptanalysis as yet, even though it is not new but just a
performance optimized derivate. So cryptanalysis that applies to BLAKE should
also apply and justify BLAKE2. However the paranoid may well trust SKEIN a bit
more than BLAKE2 and SKEIN while not being as fast as BLAKE2 is still a lot faster
than SHA2.

Compression Algorithms
======================
pcompress -c zlib file.tar file.compressed
LZFX - Ultra Fast, average compression. This algorithm is the fastest overall.
Levels: 1 - 5
LZ4 - Very Fast, better compression than LZFX.
Levels: 1 - 3
Zlib - Fast, better compression.
Levels: 1 - 9
Bzip2 - Slow, much better compression than Zlib.
Levels: 1 - 9
Compress "file.tar" using Zlib and per-thread chunk or segment size of 10MB and
Compression level 9. Compressed output is sent to stdout using '-' which is then
redirected to a file.
LZMA - Very slow. Extreme compression.
Levels: 1 - 14
Till level 9 it is standard LZMA parameters. Levels 10 - 12 use
more memory and higher match iterations so are slower. Levels
13 and 14 use larger dictionaries upto 256MB and really suck up
RAM. Use these levels only if you have at the minimum 4GB RAM on
your system.
pcompress -c zlib -l9 -s10m file.tar - > /path/to/compress_file.tar.pz
PPMD - Slow. Extreme compression for Text, average compression for binary.
In addition PPMD decompression time is also high for large chunks.
This requires lots of RAM similar to LZMA.
Levels: 1 - 14.
Adapt - Synthetic mode with text/binary detection. For pure text data PPMD is
used otherwise Bzip2 is selected per chunk.
Levels: 1 - 14
Adapt2 - Slower synthetic mode. For pure text data PPMD is otherwise LZMA is
applied. Can give very good compression ratio when splitting file
into multiple chunks.
Levels: 1 - 14
Since both LZMA and PPMD are used together memory requirements are
large especially if you are also using extreme levels above 10. For
example with 100MB chunks, Level 14, 2 threads and with or without
dedupe, it uses upto 2.5GB physical RAM (RSS).
It is possible for a single chunk to span the entire file if enough RAM is
available. However for adaptive modes to be effective for large files, especially

This uses about 6MB of physical RAM (RSS). Earlier versions of the utility before
the 0.9 release comsumed much more memory. This was improved in the later versions.
When using Linux the virtual memory consumption may appear to be very high but it
is just address space usage rather than actual RAM and should be ignored. It is only
the RSS that matters. This is a result of the memory arena mechanism in Glibc that
improves malloc() performance for multi-threaded applications.

More complete build documentation is available on the libarchive
Wiki: http://libarchive.googlecode.com/
On most Unix-like systems, you should be able to install libarchive,
bsdtar, and bsdcpio using the following common steps:
./configure
make
make install
If you need to customize the target directories or otherwise adjust
the build setting, use
./configure --help
to list the configure options.
If you are developing libarchive and need to update the
configure script and other build files:
/bin/sh build/autogen.sh
To create a distribution, please use the 'distcheck' target:
/bin/sh build/autogen.sh && ./configure && make distcheck
On Unix-like and non-Unix-like systems, use the "cmake" utility (available from
http://cmake.org/) to generate suitable build files for your platform.
Cmake requires the name of the directory containing CmakeLists.txt and
the "generator" to use for your build environment. For example, to
build with Xcode on Mac OS, you can use the following command:
cmake -G "Xcode" ~/libarchive-download-dir/
The result will be appropriate makefiles, solution files, or project
files that can be used with the corresponding development tool.
The default on Unix-like systems is to generate Makefiles, so you
can also use cmake instead of the configure script:
cmake ~/libarchive-download-dir/
make
make install
See the libarchive Wiki or the cmake site for further documentation.

Jan 07, 2009: New archive_read_disk_entry_from_file() knows about ACLs,
extended attributes, etc so that bsdtar and bsdcpio don't require
such system-specific knowledge.
Jan 03, 2009: Read filter system extensively refactored. In particular,
read filter pipelines are now built out automatically and individual
filters should be much easier to implement. Documentation on the
Googlecode Wiki explains how to implement new filters.
Dec 28, 2008: Many Windows/Visual Studio fixes from Michihiro NAKAJIMA.
Dec 28, 2008: Main libarchive development moved from FreeBSD Perforce
server to Google Code. This should make it easier for more
people to participate in libarchive development.
Dec 28, 2008: libarchive 2.6.0 released
Dec 25, 2008: libarchive 2.5.905a released
Dec 10, 2008: libarchive 2.5.904a released
Dec 04, 2008: libarchive 2.5.903a released
Nov 09, 2008: libarchive 2.5.902a released
Nov 08, 2008: libarchive 2.5.901a released
Nov 08, 2008: Start of pre-release testing for libarchive 2.6
Nov 07, 2008: Read filter refactor: The decompression routines just
consume and produce arbitrarily-sized blocks. The reblocking
from read_support_compression_none() has been pulled into the
read core. Also, the decompression bid now makes multiple
passes and stacks read filters.
Oct 21, 2008: bsdcpio: New command-line parser.
Oct 19, 2008: Internal read_ahead change: short reads are now an error
Oct 06, 2008: bsdtar: option parser no longer uses getopt_long(),
gives consistent option parsing on all platforms.
Sep 19, 2008: Jaakko Heinonen: shar utility built on libarchive
Sep 17, 2008: Pedro Giffuni: birthtime support
Sep 17, 2008: Miklos Vajna: lzma reader and test. Note: I still have
some concerns about the auto-detection (LZMA file format
doesn't support auto-detection well), so this is not yet
enabled under archive_read_support_compression_all(). For
now, you must call archive_read_support_compression_lzma() if
you want LZMA read support.
Sep 11, 2008: Ivailo Petrov: Many fixes to Windows build, new solution files
Jul 26, 2008: archive_entry now tracks which values have not been set.
This helps zip extraction (file size is often "unknown") and
time restores (tar usually doesn't know atime).
Jul 26, 2008: Joerg Sonnenberger: Performance improvements to shar writer
Jul 25, 2008: Joerg Sonnenberger: mtree write support
Jul 02, 2008: libarchive 2.5.5 released

Jun 19, 2008: bsdcpio: additional long options for better GNU cpio compat
Jun 15, 2008: Many small portability and bugfixes since 2.5.4b.
May 25, 2008: libarchive 2.5.4b released
May 21, 2008: Joerg Sonnenberger: fix bsdtar hardlink handling for newc format
May 21, 2008: More progress on Windows building. Thanks to "Scott"
for the Windows makefiles, thanks to Kees Zeelenberg for
code contributions.
May 21, 2008: Fix a number of non-exploitable integer and buffer overflows,
thanks to David Remahl at Apple for pointing these out.
May 21, 2008: Colin Percival: SIGINFO or SIGUSR1 to bsdtar prints progress info
May 16, 2008: bsdtar's test harness no longer depends on file ordering.
This was causing spurious test failures on a lot of systems.
Thanks to Bernhard R. Link for the diagnosis.
May 14, 2008: Joerg Sonnenberger: -s substitution support for bsdtar
May 13, 2008: Joerg Sonnenberger: Many mtree improvements

May 04, 2008: libarchive 2.5.3b released
* libarchive: Several fixes to link resolver to address bsdcpio crashes
* bsdcpio: -p hardlink handling fixes
* tar/pax: Ensure ustar dirnames end in '/'; be more careful about
measuring filenames when deciding what pathname fields to use
* libarchive: Mark which entry strings are set; be accurate about
distinguishing empty strings ("") from unset ones (NULL)
* tar: Don't crash reading entries with empty filenames
* libarchive_test, bsdtar_test, bsdcpio_test: Better detaults:
run all tests, delete temp dirs, summarize repeated failures
* -no-undefined to libtool for Cygwin
* libarchive_test: Skip large file tests on systems with 32-bit off_t
* iso9660: Don't bother trying to find the body of an empty file;
this works around strange behavior from some ISO9660 writers
* tar: allow -r -T to be used together
* tar: allow --format with -r or -u
* libarchive: Don't build archive.h
May 04, 2008: Simplified building: archive.h is no longer constructed
This may require additional #if conditionals on some platforms.
Mar 30, 2008: libarchive 2.5.1b released
Mar 15, 2008: libarchive 2.5.0b released
Mar 15, 2008: bsdcpio now seems to correctly write hardlinks into newc,
ustar, and old cpio archives. Just a little more testing before
bsdcpio 1.0 becomes a reality.
Mar 15, 2008: I think the new linkify() interface is finally handling
all known hardlink strategies.
Mar 15, 2008: Mtree read fixes from Joerg Sonnenberger.
Mar 15, 2008: Many new bsdtar and bsdcpio options from Joerg Sonnenberger.
Mar 15, 2008: test harnesses no longer require uudecode; they
now have built-in decoding logic that decodes the reference
files as they are needed.
Mar 14, 2008: libarchive 2.4.14 released; identical to 2.4.13 except for
a point fix for gname/uname mixup in pax format that was introduced
with the UTF-8 fixes.
Feb 26, 2008: libarchive 2.4.13 released
Feb 25, 2008: Handle path, linkname, gname, or uname that can't be converted
to/from UTF-8. Implement "hdrcharset" attribute from SUS-2008.
Feb 25, 2008: Fix name clash on NetBSD.
Feb 18, 2008: Fix writing empty 'ar' archives, per Kai Wang
Feb 18, 2008: [bsdtar] Permit appending on block devices.
Feb 09, 2008: New "linkify" resolver to help with newc hardlink writing;
bsdcpio still needs to be converted to use this.
Feb 02, 2008: Windows compatibility fixes from Ivailo Petrov, Kees Zeelenberg
Jan 30, 2008: Ignore hardlink size for non-POSIX tar archives.
Jan 22, 2008: libarchive 2.4.12 released
Jan 22, 2008: Fix bad padding when writing symlinks to newc cpio archives.
Jan 22, 2008: Verify bsdcpio_test by getting it to work against GNU cpio 2.9.
bsdcpio_test complains about missing options (-y and -z), format
of informational messages (--version, --help), and a minor formatting
issue in odc format output. After this update, bsdcpio_test uncovered
several more cosmetic issues in bsdcpio, all now fixed.
Jan 22, 2008: Experimental support for self-extracting Zip archives.
Jan 22, 2008: Extend hardlink restore strategy to work correctly with
hardlinks extracted from newc cpio files. (Which store the body
only with the last occurrence of a link.)
Dec 30, 2007: libarchive 2.4.11 released
Dec 30, 2007: Fixed a compile error in bsdcpio on some systems.
Dec 29, 2007: libarchive 2.4.10 released
Dec 29, 2007: bsdcpio 0.9.0 is ready for wider use.
Dec 29, 2007: Completed initial test harness for bsdcpio.
Dec 22, 2007: libarchive 2.4.9 released
Dec 22, 2007: Implement the remaining options for bsdcpio: -a, -q, -L, -f,
pattern selection for -i and -it.
Dec 13, 2007: libarchive 2.4.8 released
Dec 13, 2007: gzip and bzip2 compression now handle zero-byte writes correctly,
Thanks to Damien Golding for bringing this to my attention.
Dec 12, 2007: libarchive 2.4.7 released
Dec 10, 2007: libarchive 2.4.6 released
Dec 09, 2007: tar/test/test_copy.c verifies "tar -c | tar -x" copy pipeline
Dec 07, 2007: Fix a couple of minor memory leaks.
Dec 04, 2007: libarchive 2.4.5 released
Dec 04, 2007: Fix cpio/test/test_write_odc by setting the umask first.
Dec 03, 2007: libarchive 2.4.4 released

thanks to Samuli Suominen.
Dec 03, 2007: libarchive 2.4.3 released
Dec 03, 2007: Thanks to Lapo Luchini for sending me a ZIP file that
libarchive couldn't handle. Fixed a bug in handling of
"length at end" flags in ZIP files.
Dec 03, 2007: Fixed bsdcpio -help, bsdtar -help tests.
Dec 02, 2007: First cut at real bsdtar test harness.
Dec 02, 2007: libarchive 2.4.2 released
Dec 02, 2007: libarchive 2.4.1 released
Dec 02, 2007: Minor fixes, rough cut of mdoc-to-man conversion for
man pages.
Oct 30, 2007: libarchive 2.4.0 released
Oct 30, 2007: Minor compile fix thanks to Joerg Schilling.
Oct 30, 2007: Only run the format auction once at the beginning of the
archive. This is simpler and supports better error recovery.
Oct 29, 2007: Test support for very large entries in tar archives:
libarchive_test now exercises entries from 2GB up to 1TB.
Oct 27, 2007: libarchive 2.3.5 released
Oct 27, 2007: Correct some unnecessary internal data copying in the
"compression none" reader and writer; this reduces user time
by up to 2/3 in some tests. (Thanks to Jan Psota for
publishing his performance test results to GNU tar's bug-tar
mailing list; those results pointed me towards this problem.)
Oct 27, 2007: Fix for skipping archive entries that are exactly
a multiple of 4G on 32-bit platforms.
Oct 25, 2007: Fix for reading very large (>8G) tar archives; this was
broken when I put in support for new GNU tar sparse formats.
Oct 20, 2007: Initial work on new pattern-matching code for cpio; I
hope this eventually replaces the code currently in bsdtar.
Oct 08, 2007: libarchive 2.3.4 released
Oct 05, 2007: Continuing work on bsdcpio test suite.
Oct 05, 2007: New cpio.5 manpage, updates to "History" of bsdcpio.1 and
bsdtar.1 manpages.
Oct 05, 2007: Fix zip reader to immediately return EOF if you try
to read body of non-regular file. In particular, this fixes
bsdtar extraction of zip archives.
Sep 30, 2007: libarchive 2.3.3 released
Sep 26, 2007: Rework Makefile.am so that the enable/disable options
actually do the right things.
Sep 26, 2007: cpio-odc and cpio-newc archives no longer write bodies
for non-regular files.
Sep 26, 2007: Test harness for bsdcpio is in place, needs more tests written.
This is much nicer than the ragtag collection of test scripts
that bsdtar has.
Sep 20, 2007: libarchive 2.3.2 released
Sep 20, 2007: libarchive 2.3.1 broke bsdtar because the archive_write_data()
fix was implemented incorrectly.
Sep 16, 2007: libarchive 2.3.1 released
Sep 16, 2007: Many fixes to bsdcpio 0.3: handle hardlinks with -p, recognize
block size on writing, fix a couple of segfaults.
Sep 16, 2007: Fixed return value from archive_write_data() when used
with archive_write_disk() to match the documentation and other
instances of this same function.
Sep 15, 2007: Add archive_entry_link_resolver, archive_entry_strmode
Sep 11, 2007: libarchive 2.2.8 released
Sep 09, 2007: bsdcpio 0.2 supports most (not yet all) of the old POSIX spec.
Sep 01, 2007: libarchive 2.2.7 released
Aug 31, 2007: Support for reading mtree files, including an mtree.5 manpage
(A little experimental still.)
Aug 18, 2007: Read gtar 1.17 --posix --sparse entries.
Aug 13, 2007: Refined suid/sgid restore handling; it is no longer
an error if suid/sgid bits are dropped when you request
perm restore but don't request owner restore.
Aug 06, 2007: Use --enable-bsdcpio if you want to try bsdcpio
Aug 05, 2007: libarchive 2.2.6 released
Aug 05, 2007: New configure option --disable-bsdtar, thanks to Joerg
Sonnenberger.
Aug 05, 2007: Several bug fixes from FreeBSD CVS repo.
Jul 13, 2007: libarchive 2.2.5 released
Jul 12, 2007: libarchive 2.2.4 released
Jul 12, 2007: Thanks to Colin Percival's help in diagnosing and
fixing several critical security bugs. Details available at
http://security.freebsd.org/advisories/FreeBSD-SA-07:05.libarchive.asc
May 26, 2007: libarchive 2.2.3 released
May 26, 2007: Fix memory leaks in ZIP reader and shar writer, add some
missing system headers to archive_entry.h, dead code cleanup
from Colin Percival, more tests for gzip/bzip2, fix an
EOF anomaly in bzip2 decompression.
May 12, 2007: libarchive 2.2.2 released
May 12, 2007: Fix archive_write_disk permission restore by cloning
entry passed into write_header so that permission info is
still available at finish_entry time. (archive_read_extract()
worked okay because it held onto the passed-in entry, but
direct consumers of archive_write_disk would break). This
required fixing archive_entry_clone(), which now works and has
a reasonably complete test case.
May 10, 2007: Skeletal cpio implementation.
May 06, 2007: libarchive 2.2.1 released
May 06, 2007: Flesh out a lot more of test_entry.c so as to catch
problems such as the device node breakage before releasing <sigh>.
May 05, 2007: Fix a bad bug introduced in 2.1.9 that broke device
node entries in tar archives.
May 03, 2007: Move 'struct stat' out of archive_entry core as well.
This removes some portability headaches and fixes a bunch
of corner cases that arise when manipulating archives on
dissimilar systems.
Apr 30, 2007: libarchive 2.1.10 released
Apr 31, 2007: Minor code cleanup.
Apr 24, 2007: libarchive 2.1.9 released
Apr 24, 2007: Fix some recently-introduced problems with libraries
(Just let automake handle it and it all works much better.)
Finish isolating major()/minor()/makedev() in archive_entry.c.
Apr 23, 2007: libarchive 2.1.8 released
Apr 23, 2007: Minor fixes found from building on MacOS X
Apr 22, 2007: libarchive 2.1.7 released
Apr 22, 2007: Eliminated all uses of 'struct stat' from the
format readers/writers. This should improve portability;
'struct stat' is now only used in archive_entry and in
code that actually touches the disk.
Apr 17, 2007: libarchive 2.1.6 released
Libarchive now compiles and passes all tests on Interix.
Apr 16, 2007: libarchive 2.1.5 released
Apr 15, 2007: libarchive 2.1b2 released
Apr 15, 2007: New libarchive_internals.3 documentation of internal APIs.
Not complete, but should prove helpful.
Apr 15, 2007: Experimental "read_compress_program" and "write_compress_program"
for using libarchive with external compression. Not yet
well tested, and likely has portability issues. Feedback
appreciated.
Apr 14, 2007: libarchive 2.0.31 released
Apr 14, 2007: More fixes for Interix, more 'ar' work
Apr 14, 2007: libarchive 2.0.30 released
Apr 13, 2007: libarchive now enforces trailing '/' on dirs
written to tar archives
Apr 11, 2007: libarchive 2.0.29 released
Apr 11, 2007: Make it easier to statically configure for different platforms.
Apr 11, 2007: Updated config.guess, config.sub, libtool
Apr 06, 2007: libarchive 2.0.28 released
Apr 06, 2007: 'ar' format read/write support thanks to Kai Wang.
Apr 01, 2007: libarchive 2.0.27 released
Mar 31, 2007: Several minor fixes from Colin Percival and Joerg Sonnenberger.
Mar 12, 2007: libarchive 2.0.25 released
Mar 12, 2007: Fix broken --unlink flag.
Mar 11, 2007: libarchive 2.0.24 released
Mar 10, 2007: Correct an ACL blunder that causes any ACL with an entry
that refers to a non-existent user or group to not be restored correctly.
The fix both makes the parser more tolerant (so that archives created
with the buggy ACLs can be read now) and corrects the ACL formatter.
Mar 10, 2007: More work on test portability to Linux.
Mar 10, 2007: libarchive 2.0.22 released
Mar 10, 2007: Header cleanups; added linux/fs.h, removed
some unnecessary headers, added #include guards in bsdtar.
If you see any obvious compile failures from this, let me know.
Mar 10, 2007: Work on bsdtar test scripts: not yet robust enough
to enable as part of "make check", but getting better.
Mar 10, 2007: libarchive now returns ARCHIVE_FAILED when
a header write fails in a way that only affects this item.
Less bad than ARCHIVE_FATAL, but worse than ARCHIVE_WARN.
Mar 07, 2007: libarchive 2.0.21 released
Mar 07, 2007: Add some ACL tests (only for the system-independent
portion of the ACL support for now).
Mar 07, 2007: tar's ability to read ACLs off disk got
turned off for FreeBSD; re-enable it. (ACL restores and
libarchive support for storing/reading ACLs from pax
archives was unaffected.)
Mar 02, 2007: libarchive 2.0.20 released
Mar 2, 2007: It's not perfect, but it's pretty good.
Libarchive 2.0 is officially out of beta.
Feb 28, 2007: libarchive 2.0b17 released
Feb 27, 2007: Make the GID restore checks more robust by checking
whether the current user has too few or too many privileges.
Feb 26, 2007: libarchive 2.0b15 released
Feb 26, 2007: Don't lose symlinks when extracting from ISOs.
Thanks to Diego "Flameeyes" Pettenò for telling me about the
broken testcase on Gentoo that (finally!) led me to the cause
of this long-standing bug.
Feb 26, 2007: libarchive 2.0b14 released
Feb 26, 2007: Fix a broken test on platforms that lack lchmod().
Feb 25, 2007: libarchive 2.0b13 released
Feb 25, 2007: Empty archives were being written as empty files,
without a proper end-of-archive marker. Fixed.
Feb 23, 2007: libarchive 2.0b12 released
Feb 22, 2007: Basic security checks added: _EXTRACT_SECURE_NODOTDOT
and _EXTRACT_SECURE_SYMLINK. These checks used to be in bsdtar,
but they belong down in libarchive where they can be used by
other tools and where they can be better optimized.
Feb 11, 2007: libarchive 2.0b11 released
Feb 10, 2007: Fixed a bunch of errors in libarchive's handling
of EXTRACT_PERM and EXTRACT_OWNER, especially relating
to SUID and SGID bits.
Jan 31, 2007: libarchive 2.0b9 released
Jan 31, 2007: Added read support for "empty" archives as a
distinct archive format. Bsdtar uses this to handle, e.g.,
"touch foo.tar; tar -rf foo.tar"
Jan 22, 2007: libarchive 2.0b6 released
Jan 22, 2007: archive_write_disk API is now in place. It provides
a finer-grained interface than archive_read_extract. In particular,
you can use it to create objects on disk without having an archive
around (just feed it archive_entry objects describing what you
want to create), you can override the uname/gname-to-uid/gid lookups
(minitar uses this to avoid getpwXXX() and getgrXXX() bloat).
Jan 09, 2007: libarchive 2.0a3 released
Jan 9, 2007: archive_extract is now much better; it handles the
most common cases with a minimal number of system calls.
Some features still need a lot of testing, especially corner
cases involving objects that already exist on disk. I expect
the next round of API overhaul will simplify building test cases.
Jan 9, 2007: a number of fixes thanks to Colin Percival, especially
corrections to the skip() framework and handling of large files.
Jan 9, 2007: Fixes for large ISOs. The code should correctly handle
very large ISOs with entries up to 4G. Thanks to Robert Sciuk
for pointing out these issues.
Sep 05, 2006: libarchive 1.3.1 released
Sep 5, 2006: Bump version to 1.3 for new I/O wrappers.
Sep 4, 2006: New memory and FILE read/write wrappers.
Sep 4, 2006: libarchive test harness is now minimally functional;
it's located a few minor bugs in error-handling logic
Aug 17, 2006: libarchive 1.2.54 released
Aug 17, 2006: Outline ABI changes for libarchive 2.0; these
are protected behind #ifdef's until I think I've found everything
that needs to change.
Aug 17, 2006: Fix error-handling in archive_read/write_close()
They weren't returning any errors before.
Aug 17, 2006: Fix recursive-add logic to not trigger if it's not set
Fixes a bug adding files when writing archive to pipe or when
using archive_write_open() directly.
Jul 2006: New "skip" handling improves performance extracting
single files from large uncompressed archives.
Mar 21, 2006: 1.2.52 released
Mar 21, 2006: Fix -p on platforms that don't have platform-specific
extended attribute code.
Mar 20, 2006: Add NEWS file; fill in some older history from other
files. I'll try to keep this file up-to-date from now on.
OLDER NEWS SUMMARIES
Mar 19, 2006: libarchive 1.2.51 released
Mar 18, 2006: Many fixes to extended attribute support, including a redesign
of the storage format to simplify debugging.
Mar 12, 2006: Remove 'tp' support; it was a fun idea, but not worth
spending much time on.
Mar 11, 2006: Incorporated Jaakko Heinonen's still-experimental support
for extended attributes (Currently Linux-only.).
Mar 11, 2006: Reorganized distribution package: There is now one tar.gz
file that builds both libarchive and bsdtar.
Feb 13, 2006: Minor bug fixes: correctly read cpio device entries, write
Pax attribute entry names.
Nov 7, 2005: Experimental 'tp' format support in libarchive. Feedback
appreciated; this is not enabled by archive_read_support_format_all()
yet as I'm not quite content with the format detection heuristics.
Nov 7, 2005: Some more portability improvements thanks to Darin Broady,
minor bugfixes.
Oct 12, 2005: Use GNU libtool to build shared libraries on many systems.
Aug 9, 2005: Correctly detect that MacOS X does not have POSIX ACLs.
Apr 17, 2005: Kees Zeelenberg has ported libarchive and bsdtar to Windows:
http://gnuwin32.sourceforge.net/
Apr 11, 2005: Extended Zip/Zip64 support thanks to Dan Nelson. -L/-h
fix from Jaakko Heinonen.
Mar 12, 2005: archive_read_extract can now handle very long
pathnames (I've tested with pathnames up to 1MB).
Mar 12, 2005: Marcus Geiger has written an article about libarchive
http://xsnil.antbear.org/2005/02/05/archive-mit-libarchive-verarbeiten/
including examples of using it from Objective-C. His MoinX
http://moinx.antbear.org/ desktop Wiki uses
libarchive for archiving and restoring Wiki pages.
Jan 22, 2005: Preliminary ZIP extraction support,
new directory-walking code for bsdtar.
Jan 16, 2005: ISO9660 extraction code added; manpage corrections.
May 22, 2004: Many gtar-compatible long options have been added; almost
all FreeBSD ports extract correctly with bsdtar.
May 18, 2004: bsdtar can read Solaris, HP-UX, Unixware, star, gtar,
and pdtar archives.

Currently, the library automatically detects and reads the following fomats:
* GNU tar format (including GNU long filenames, long link names, and sparse files)
* Solaris 9 extended tar format (including ACLs)
* Old V7 tar archives
* POSIX ustar
* POSIX pax interchange format
* POSIX octet-oriented cpio
* SVR4 ASCII cpio
* POSIX octet-oriented cpio
* Binary cpio (big-endian or little-endian)
* ISO9660 CD-ROM images (with optional Rockridge or Joliet extensions)
* ZIP archives (with uncompressed or "deflate" compressed entries)
* GNU and BSD 'ar' archives
* 'mtree' format
* 7-Zip archives
* Microsoft CAB format
* LHA and LZH archives
* RAR archives
* XAR archives
The library also detects and handles any of the following before evaluating the archive:
* uuencoded files
* files with RPM wrapper
* gzip compression
* bzip2 compression
* compress/LZW compression
* lzma, lzip, and xz compression
The library can create archives in any of the following formats:
* POSIX ustar
* POSIX pax interchange format
* "restricted" pax format, which will create ustar archives except for
entries that require pax extensions (for long filenames, ACLs, etc).
* Old GNU tar format
* POSIX octet-oriented cpio
* SVR4 "newc" cpio
* shar archives
* ZIP archives (with uncompressed or "deflate" compressed entries)
* GNU and BSD 'ar' archives
* 'mtree' format
* ISO9660 format
* 7-Zip archives
* XAR archives
When creating archives, the result can be filtered with any of the following:
* uuencode
* gzip compression
* bzip2 compression
* compress/LZW compression
* lzma, lzip, and xz compression
Notes about the library architecture:
* This is a heavily stream-oriented system. There is no direct
support for in-place modification or random access.
* The library is designed to be extended with new compression and
archive formats. The only requirement is that the format be
readable or writable as a stream and that each archive entry be
independent. There are articles on the libarchive Wiki explaining
how to extend libarchive.
* On read, compression and format are always detected automatically.
* I've attempted to minimize static link pollution. If you don't
explicitly invoke a particular feature (such as support for a
particular compression or format), it won't get pulled in.
In particular, if you don't explicitly enable a particular
compression or decompression support, you won't need to link
against the corresponding compression or decompression libraries.
This also reduces the size of statically-linked binaries in
environments where that matters.
* On read, the library accepts whatever blocks you hand it.
Your read callback is free to pass the library a byte at a time
or mmap the entire archive and give it to the library at once.
On write, the library always produces correctly-blocked output.
* The object-style approach allows you to have multiple archive streams
open at once. bsdtar uses this in its "@archive" extension.
* The archive itself is read/written using callback functions.
You can read an archive directly from an in-memory buffer or
write it to a socket, if you wish. There are some utility
functions to provide easy-to-use "open file," etc, capabilities.
* The read/write APIs are designed to allow individual entries
to be read or written to any data source: You can create
a block of data in memory and add it to a tar archive without
first writing a temporary file. You can also read an entry from
an archive and write the data directly to a socket. If you want
to read/write entries to disk, there are convenience functions to
make this especially easy.
* Note: "pax interchange format" is really an extended tar format,
despite what the name says.

## (We might end up doing this anyway to support other compilers.)

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file

## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.

* Utility to match up hardlinks.
*
* The 'struct archive_entry_linkresolver' is a cache of archive entries
* for files with multiple links. Here's how to use it:
* 1. Create a lookup object with archive_entry_linkresolver_new()
* 2. Tell it the archive format you're using.
* 3. Hand each archive_entry to archive_entry_linkify().
* That function will return 0, 1, or 2 entries that should
* be written.
* 4. Call archive_entry_linkify(resolver, NULL) until
* no more entries are returned.
* 5. Call archive_entry_linkresolver_free(resolver) to free resources.
*
* The entries returned have their hardlink and size fields updated
* appropriately. If an entry is passed in that does not refer to
* a file with multiple links, it is returned unchanged. The intention
* is that you should be able to simply filter all entries through
* this machine.
*
* To make things more efficient, be sure that each entry has a valid
* nlinks value. The hardlink cache uses this to track when all links
* have been found. If the nlinks value is zero, it will keep every
* name in the cache indefinitely, which can use a lot of memory.
*
* Note that archive_entry_size() is reset to zero if the file
* body should not be written to the archive. Pay attention!
*/
struct archive_entry_linkresolver;
/*
* There are three different strategies for marking hardlinks.
* The descriptions below name them after the best-known
* formats that rely on each strategy:
*
* "Old cpio" is the simplest, it always returns any entry unmodified.
* As far as I know, only cpio formats use this. Old cpio archives
* store every link with the full body; the onus is on the dearchiver
* to detect and properly link the files as they are restored.
* "tar" is also pretty simple; it caches a copy the first time it sees
* any link. Subsequent appearances are modified to be hardlink
* references to the first one without any body. Used by all tar
* formats, although the newest tar formats permit the "old cpio" strategy
* as well. This strategy is very simple for the dearchiver,
* and reasonably straightforward for the archiver.
* "new cpio" is trickier. It stores the body only with the last
* occurrence. The complication is that we might not
* see every link to a particular file in a single session, so
* there's no easy way to know when we've seen the last occurrence.
* The solution here is to queue one link until we see the next.
* At the end of the session, you can enumerate any remaining
* entries by calling archive_entry_linkify(NULL) and store those
* bodies. If you have a file with three links l1, l2, and l3,
* you'll get the following behavior if you see all three links:
* linkify(l1) => NULL (the resolver stores l1 internally)
* linkify(l2) => l1 (resolver stores l2, you write l1)
* linkify(l3) => l2, l3 (all links seen, you can write both).
* If you only see l1 and l2, you'll get this behavior:
* linkify(l1) => NULL
* linkify(l2) => l1
* linkify(NULL) => l2 (at end, you retrieve remaining links)
* As the name suggests, this strategy is used by newer cpio variants.
* It's noticeably more complex for the archiver, slightly more complex
* for the dearchiver than the tar strategy, but makes it straightforward
* to restore a file using any link by simply continuing to scan until
* you see a link that is stored with a body. In contrast, the tar
* strategy requires you to rescan the archive from the beginning to
* correctly extract an arbitrary link.
