Dag Wieers b66bf8e7a4 Revert PR #3575 since it causes problems related to exclude patterns (#3767) 
* Revert PR #3575 since it causes problems related to exclude patterns

By using a different method for getting archive filelists, and extracting we introduced new problems related to excluding based on gtar patterns.

As a result files that would be excluded by gtar, would still be in the filelist. Implementing our own gtar compatible pattern exclusion mechanism is near to impossible (believe me, we looked at it...). The best way is to look at the original problem and deal with that, and ensure that extraction and filelists are done with the exact same tool and exact same options.

The solution is to decode the octal unicode representation in gtar's output back to unicode. Since gtar has no problem extracting these files in LANG=C, we simply has to compensate for it.

This reverts #3575 and fixes #11348.

* Implement codecs.escape_decode() instead of decode("string_escape") for python3

module: unarchive
version_added: 1.4
short_description: Unpacks an archive after (optionally) copying it from the local machine.
extends_documentation_fragment: files
description:
- The M(unarchive) module unpacks an archive. By default, it will copy the source file from the local system to the target before unpacking - set copy=no to unpack an archive which already exists on the target..
options:
src:
description:
- If copy=yes (default), local path to archive file to copy to the target server; can be absolute or relative. If copy=no, path on the target server to existing archive file to unpack.
- If copy=no and src contains ://, the remote machine will download the file from the url first. (version_added 2.0)
required: true
default: null
dest:
description:
- Remote absolute path where the archive should be unpacked
required: true
default: null
copy:
description:
- "If true, the file is copied from local 'master' to the target machine, otherwise, the plugin will look for src archive at the target machine."
required: false
choices: [ "yes", "no" ]
default: "yes"
creates:
description:
- a filename, when it already exists, this step will B(not) be run.
required: no
default: null
version_added: "1.6"
list_files:
description:
- If set to True, return the list of files that are contained in the tarball.
required: false
choices: [ "yes", "no" ]
default: "no"
version_added: "2.0"
exclude:
description:
- List the directory and file entries that you would like to exclude from the unarchive action.
required: false
default: []
version_added: "2.1"
keep_newer:
description:
- Do not replace existing files that are newer than files from the archive.
required: false
default: no
version_added: "2.1"
extra_opts:
description:
- Specify additional options by passing in an array.
default:
required: false
version_added: "2.1"
validate_certs:
description:
- This only applies if using a https url as the source of the file.
- This should only set to C(no) used on personally controlled sites using self-signed cer
- Prior to 2.2 the code worked as if this was set to C(yes).
required: false
default: "yes"
choices: ["yes", "no"]
version_added: "2.2"
author: "Dag Wieers (@dagwieers)"
todo:
- re-implement tar support using native tarfile module
- re-implement zip support using native zipfile module
notes:
- requires C(gtar)/C(unzip) command on target host
- can handle I(gzip), I(bzip2) and I(xz) compressed as well as uncompressed tar files
- detects type of archive automatically
- uses gtar's C(--diff arg) to calculate if changed or not. If this C(arg) is not
supported, it will always unpack the archive
- existing files/directories in the destination which are not in the archive
are not touched. This is the same behavior as a normal archive extraction
- existing files/directories in the destination which are not in the archive
are ignored for purposes of deciding if the archive should be unpacked or not
'''

# Example from Ansible Playbooks
