|

A Python interface to libarchive. It uses the standard ctypes_ module to
|
||||
dynamically load and access the C library.
|
||||
|
||||
.. _ctypes: https://docs.python.org/3/library/ctypes.html
|
||||
|
||||
Installation
|
||||
============
|
||||
|
||||
pip install libarchive-c
|
||||
|
||||
Compatibility
|
||||
=============
|
||||
|
||||
python
|
||||
------
|
||||
|
||||
python-libarchive-c is currently tested with python 3.8, 3.9, 3.10 and 3.11.
|
||||
|
||||
If you find an incompatibility with older versions you can send us a small patch,
|
||||
but we won't accept big changes.
|
||||
|
||||
libarchive
|
||||
----------
|
||||
|
||||
python-libarchive-c may not work properly with obsolete versions of libarchive such as the ones included in MacOS. In that case you can install a recent version of libarchive (e.g. with ``brew install libarchive`` on MacOS) and use the ``LIBARCHIVE`` environment variable to point python-libarchive-c to it::
|
||||
|
||||
export LIBARCHIVE=/usr/local/Cellar/libarchive/3.3.3/lib/libarchive.13.dylib
|
||||
|
||||
Usage
|
||||
=====
|
||||
|
||||
Import::
|
||||
|
||||
import libarchive
|
||||
|
||||
Extracting archives
|
||||
-------------------
|
||||
|
||||
To extract an archive, use the ``extract_file`` function::
|
||||
|
||||
os.chdir('/path/to/target/directory')
|
||||
libarchive.extract_file('test.zip')
|
||||
|
||||
Alternatively, the ``extract_memory`` function can be used to extract from a buffer,
|
||||
and ``extract_fd`` from a file descriptor.
|
||||
|
||||
The ``extract_*`` functions all have an integer ``flags`` argument which is passed
|
||||
directly to the C function ``archive_write_disk_set_options()``. You can import
|
||||
the ``EXTRACT_*`` constants from the ``libarchive.extract`` module and see the
|
||||
official description of each flag in the ``archive_write_disk(3)`` man page.
|
||||
|
||||
By default, when the ``flags`` argument is ``None``, the ``SECURE_NODOTDOT``,
|
||||
``SECURE_NOABSOLUTEPATHS`` and ``SECURE_SYMLINKS`` flags are passed to
|
||||
libarchive, unless the current directory is the root (``/``).
|
||||
|
||||
Reading archives
|
||||
----------------
|
||||
|
||||
To read an archive, use the ``file_reader`` function::
|
||||
|
||||
with libarchive.file_reader('test.7z') as archive:
|
||||
for entry in archive:
|
||||
for block in entry.get_blocks():
|
||||
...
|
||||
|
||||
Alternatively, the ``memory_reader`` function can be used to read from a buffer,
|
||||
``fd_reader`` from a file descriptor, ``stream_reader`` from a stream object
|
||||
(which must support the standard ``readinto`` method), and ``custom_reader``
|
||||
from anywhere using callbacks.
|
||||
|
||||
To learn about the attributes of the ``entry`` object, see the ``libarchive/entry.py``
|
||||
source code or run ``help(libarchive.entry.ArchiveEntry)`` in a Python shell.
|
||||
|
||||
Displaying progress
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
If your program processes large archives, you can keep track of its progress
|
||||
with the ``bytes_read`` attribute. Here's an example of a progress bar using
|
||||
`tqdm <https://pypi.org/project/tqdm/>`_::
|
||||
|
||||
with tqdm(total=os.stat(archive_path).st_size, unit='bytes') as pbar, \
|
||||
libarchive.file_reader(archive_path) as archive:
|
||||
for entry in archive:
|
||||
...
|
||||
pbar.update(archive.bytes_read - pbar.n)
|
||||
|
||||
Creating archives
|
||||
-----------------
|
||||
|
||||
To create an archive, use the ``file_writer`` function::
|
||||
|
||||
from libarchive.entry import FileType
|
||||
|
||||
with libarchive.file_writer('test.tar.gz', 'ustar', 'gzip') as archive:
|
||||
# Add the `libarchive/` directory and everything in it (recursively),
|
||||
# then the `README.rst` file.
|
||||
archive.add_files('libarchive/', 'README.rst')
|
||||
# Add a regular file defined from scratch.
|
||||
data = b'foobar'
|
||||
archive.add_file_from_memory('../escape-test', len(data), data)
|
||||
# Add a directory defined from scratch.
|
||||
early_epoch = (42, 42) # 1970-01-01 00:00:42.000000042
|
||||
archive.add_file_from_memory(
|
||||
'metadata-test', 0, b'',
|
||||
filetype=FileType.DIRECTORY, permission=0o755, uid=4242, gid=4242,
|
||||
atime=early_epoch, mtime=early_epoch, ctime=early_epoch, birthtime=early_epoch,
|
||||
)
|
||||
|
||||
Alternatively, the ``memory_writer`` function can be used to write to a memory buffer,
|
||||
``fd_writer`` to a file descriptor, and ``custom_writer`` to a callback function.
|
||||
|
||||
For each of those functions, the mandatory second argument is the archive format,
|
||||
and the optional third argument is the compression format (called “filter” in
|
||||
libarchive). The acceptable values are listed in ``libarchive.ffi.WRITE_FORMATS``
|
||||
and ``libarchive.ffi.WRITE_FILTERS``.
|
||||
|
||||
File metadata codecs
|
||||
--------------------
|
||||
|
||||
By default, UTF-8 is used to read and write file attributes from and to archives.
|
||||
A different codec can be specified through the ``header_codec`` arguments of the
|
||||
``*_reader`` and ``*_writer`` functions. Example::
|
||||
|
||||
with libarchive.file_writer('test.tar', 'ustar', header_codec='cp037') as archive:
|
||||
...
|
||||
with file_reader('test.tar', header_codec='cp037') as archive:
|
||||
...
|
||||
|
||||
In addition to file paths (``pathname`` and ``linkpath``), the specified codec is
|
||||
used to encode and decode user and group names (``uname`` and ``gname``).

Description: Python3 interface to libarchive
|
||||
The libarchive library provides a flexible interface for reading and writing
|
||||
archives in various formats such as tar and cpio. libarchive also supports
|
||||
reading and writing archives compressed using various compression filters such
|
||||
as gzip and bzip2.
|
||||
.
|
||||
This package contains a Python3 interface to libarchive written using the
|
||||
standard ctypes module to dynamically load and access the C library.

License: CC-0
|
||||
Statement of Purpose
|
||||
.
|
||||
The laws of most jurisdictions throughout the world automatically
|
||||
confer exclusive Copyright and Related Rights (defined below) upon
|
||||
the creator and subsequent owner(s) (each and all, an "owner") of an
|
||||
original work of authorship and/or a database (each, a "Work").
|
||||
.
|
||||
Certain owners wish to permanently relinquish those rights to a Work
|
||||
for the purpose of contributing to a commons of creative, cultural
|
||||
and scientific works ("Commons") that the public can reliably and
|
||||
without fear of later claims of infringement build upon, modify,
|
||||
incorporate in other works, reuse and redistribute as freely as
|
||||
possible in any form whatsoever and for any purposes, including
|
||||
without limitation commercial purposes. These owners may contribute
|
||||
to the Commons to promote the ideal of a free culture and the further
|
||||
production of creative, cultural and scientific works, or to gain
|
||||
reputation or greater distribution for their Work in part through the
|
||||
use and efforts of others.
|
||||
.
|
||||
For these and/or other purposes and motivations, and without any
|
||||
expectation of additional consideration or compensation, the person
|
||||
associating CC0 with a Work (the "Affirmer"), to the extent that he
|
||||
or she is an owner of Copyright and Related Rights in the Work,
|
||||
voluntarily elects to apply CC0 to the Work and publicly distribute
|
||||
the Work under its terms, with knowledge of his or her Copyright and
|
||||
Related Rights in the Work and the meaning and intended legal effect
|
||||
of CC0 on those rights.
|
||||
.
|
||||
1. Copyright and Related Rights. A Work made available under CC0 may
|
||||
be protected by copyright and related or neighboring rights
|
||||
("Copyright and Related Rights"). Copyright and Related Rights
|
||||
include, but are not limited to, the following:
|
||||
.
|
||||
i. the right to reproduce, adapt, distribute, perform, display,
|
||||
communicate, and translate a Work;
|
||||
ii. moral rights retained by the original author(s) and/or
|
||||
performer(s);
|
||||
iii. publicity and privacy rights pertaining to a person's image
|
||||
or likeness depicted in a Work;
|
||||
iv. rights protecting against unfair competition in regards to a
|
||||
Work, subject to the limitations in paragraph 4(a), below;
|
||||
v. rights protecting the extraction, dissemination, use and
|
||||
reuse of data in a Work;
|
||||
vi. database rights (such as those arising under Directive
|
||||
96/9/EC of the European Parliament and of the Council of 11
|
||||
March 1996 on the legal protection of databases, and under
|
||||
any national implementation thereof, including any amended or
|
||||
successor version of such directive); and
|
||||
vii. other similar, equivalent or corresponding rights throughout
|
||||
the world based on applicable law or treaty, and any national
|
||||
implementations thereof.
|
||||
.
|
||||
2. Waiver. To the greatest extent permitted by, but not in
|
||||
contravention of, applicable law, Affirmer hereby overtly, fully,
|
||||
permanently, irrevocably and unconditionally waives, abandons, and
|
||||
surrenders all of Affirmer's Copyright and Related Rights and
|
||||
associated claims and causes of action, whether now known or
|
||||
unknown (including existing as well as future claims and causes of
|
||||
action), in the Work (i) in all territories worldwide, (ii) for
|
||||
the maximum duration provided by applicable law or treaty
|
||||
(including future time extensions), (iii) in any current or future
|
||||
medium and for any number of copies, and (iv) for any purpose
|
||||
whatsoever, including without limitation commercial, advertising
|
||||
or promotional purposes (the "Waiver"). Affirmer makes the Waiver
|
||||
for the benefit of each member of the public at large and to the
|
||||
detriment of Affirmer's heirs and successors, fully intending that
|
||||
such Waiver shall not be subject to revocation, rescission,
|
||||
cancellation, termination, or any other legal or equitable action
|
||||
to disrupt the quiet enjoyment of the Work by the public as
|
||||
contemplated by Affirmer's express Statement of Purpose.
|
||||
.
|
||||
3. Public License Fallback. Should any part of the Waiver for any
|
||||
reason be judged legally invalid or ineffective under applicable law,
|
||||
then the Waiver shall be preserved to the maximum extent permitted
|
||||
taking into account Affirmer's express Statement of Purpose. In
|
||||
addition, to the extent the Waiver is so judged Affirmer hereby
|
||||
grants to each affected person a royalty-free, non transferable, non
|
||||
sublicensable, non exclusive, irrevocable and unconditional license
|
||||
to exercise Affirmer's Copyright and Related Rights in the Work (i)
|
||||
in all territories worldwide, (ii) for the maximum duration provided
|
||||
by applicable law or treaty (including future time extensions), (iii)
|
||||
in any current or future medium and for any number of copies, and
|
||||
(iv) for any purpose whatsoever, including without limitation
|
||||
commercial, advertising or promotional purposes (the "License"). The
|
||||
License shall be deemed effective as of the date CC0 was applied by
|
||||
Affirmer to the Work. Should any part of the License for any reason
|
||||
be judged legally invalid or ineffective under applicable law, such
|
||||
partial invalidity or ineffectiveness shall not invalidate the
|
||||
remainder of the License, and in such case Affirmer hereby affirms
|
||||
that he or she will not (i) exercise any of his or her remaining
|
||||
Copyright and Related Rights in the Work or (ii) assert any
|
||||
associated claims and causes of action with respect to the Work, in
|
||||
either case contrary to Affirmer's express Statement of Purpose.
|
||||
.
|
||||
4. Limitations and Disclaimers.
|
||||
.
|
||||
a. No trademark or patent rights held by Affirmer are waived,
|
||||
abandoned, surrendered, licensed or otherwise affected by
|
||||
this document.
|
||||
b. Affirmer offers the Work as-is and makes no representations
|
||||
or warranties of any kind concerning the Work, express,
|
||||
implied, statutory or otherwise, including without limitation
|
||||
warranties of title, merchantability, fitness for a
|
||||
particular purpose, non infringement, or the absence of
|
||||
latent or other defects, accuracy, or the present or absence
|
||||
of errors, whether or not discoverable, all to the greatest
|
||||
extent permissible under applicable law.
|
||||
c. Affirmer disclaims responsibility for clearing rights of
|
||||
other persons that may apply to the Work or any use thereof,
|
||||
including without limitation any person's Copyright and
|
||||
Related Rights in the Work. Further, Affirmer disclaims
|
||||
responsibility for obtaining any necessary consents,
|
||||
permissions or other rights required for any use of the
|
||||
Work.
|
||||
d. Affirmer understands and acknowledges that Creative Commons
|
||||
is not a party to this document and has no duty or obligation
|
||||
with respect to this CC0 or use of the Work.
