Project Description

To eliminate some problems with installation, the public API has been moved from the `libarchive` package to `libarchive.public`, and will be reflected in the next release. This is backwards-incompatible, but would otherwise prevent the install due to broken dependencies during install.

Introduction

A ctypes-based adapter to libarchive. The source-code is written to be clear and intuitive.

Even 7-Zip is supported for both reading and writing.

I could definitely use some help, if any is available. Completeness will require a bit more work (see libarchive’s archive.h and archive_entry.h).

Installation

PyPI:

$ sudo pip install libarchive

Notes

The Ubuntu libarchive package maintainer refuses to place a “libarchive.so” symlink, so you’ll have to place this yourself. Depending on your Ubuntu, this can be libarchive.so.12, libarchive.so.13, or libarchive.so.14 .

For example:

/usr/lib/x86_64-linux-gnu$ sudo ln -s libarchive.so.12 libarchive.so

Task List

Done Task
X Read entries from physical file
X Read entries from archive hosted in memory buffer
X Write physical files from archive
X Load memory buffer from archive
X Populate physical archive from physical files
X Populate archive hosted in memory buffer
Populate archive entries from memory buffers
Fill-out the entry object’s information/accessors

Examples

To extract to the current directory from a physical file (and print each relative filepath):

import libarchive.public

for entry in libarchive.public.file_pour('/tmp/test.zip'):
    print(e)

To extract to the current directory from memory:

import libarchive.public

with open('/tmp/test.zip', 'rb') as f:
    for entry in libarchive.public.memory_pour(f.read()):
        print(e)

To read files from a physical archive:

import libarchive.public

with libarchive.public.file_reader('test.7z') as e:
    for entry in e:
        with open('/tmp/' + str(entry), 'wb') as f:
            for block in entry.get_blocks():
                f.write(block)

To read files from memory:

import libarchive.public

with open('test.7z', 'rb') as f:
    buffer_ = f.read()
    with libarchive.public.memory_reader(buffer_) as e:
        for entry in e:
            with open('/tmp/' + str(entry), 'wb') as f:
                for block in entry.get_blocks():
                    f.write(block)

To specify a format and/or filter for reads (rather than detecting it):

import libarchive.public
import libarchive.constants

with open('test.7z', 'rb') as f:
    buffer_ = f.read()
    with libarchive.public.memory_reader(
            buffer_,
            format_code=libarchive.constants.ARCHIVE_FORMAT_TAR_USTAR,
            filter_code=libarchive.constants.ARCHIVE_FILTER_GZIP
        ) as e:
        for entry in e:
            with open('/tmp/' + str(entry), 'wb') as f:
                for block in entry.get_blocks():
                    f.write(block)

To read the “filetype” flag for each entry:

import libarchive.public

with open('test.7z', 'rb') as f:
    buffer_ = f.read()
    with libarchive.public.memory_reader(f.read()) as e:
        for entry in e:
            print(e.filetype)

The output of this is:

EntryFileType(IFREG=True, IFLNK=True, IFSOCK=True, IFCHR=False, IFBLK=False, IFDIR=False, IFIFO=False)
EntryFileType(IFREG=True, IFLNK=True, IFSOCK=True, IFCHR=False, IFBLK=False, IFDIR=False, IFIFO=False)
EntryFileType(IFREG=True, IFLNK=True, IFSOCK=True, IFCHR=False, IFBLK=False, IFDIR=False, IFIFO=False)

To create a physical archive from physical files:

import libarchive.public
import libarchive.constants

for entry in libarchive.public.create_file(
                'create.7z',
                libarchive.constants.ARCHIVE_FORMAT_7ZIP,
                ['/etc/profile']):
    print(entry)

To create an archive in memory from physical files:

import libarchive.public
import libarchive.constants

with open('/tmp/new.7z', 'wb') as f:
    def writer(buffer_, length):
        f.write(buffer_)
        return length

    for entry in libarchive.public.create_generic(
                    writer,
                    format_name=libarchive.constants.ARCHIVE_FORMAT_7ZIP,
                    files=['/etc/profile']):
        print(entry)
