* Detection of handler depends on the wrong handler failing to list the contents of the tarfile.
Use explicit compression types with the python tarfile library to
achieve that.
* bytearray isn't available in python2.4
* unarchive: use Python's tarfile module for tar listing
fixes https://github.com/ansible/ansible/issues/11348
Depending on the current active locale, `tar`'s file listing can end up
spitting backslash-escaped characters. Unfortunately, when that happens,
we end up with double-escaped backslashes, giving us a wrong path,
making our action fail.
We could try un-double-escaping our paths, but that would be complicated
and, I think, error-prone. The easiest way forward seemed to simply use
the `tarfile` module.
Why use it only for listing? Because the `unarchive` option also
supports the `extra_opts` option, and that supporting this would require
us to mimick `tar`'s interface.
For listing files, however, I don't think that the loss of `extra_opts`
support causes problems (well, I hope so).
* unarchive: re-add xz decompression support
Following previous change to use Python's `tarfile` module for tar file
listing, we lost `xz` decompression support. This commits re-add it by
adding a special case in `TarXzArchive` that pre-decompresses the source
file.
* WIP: Making unarchive idempotent
Currently unarchive is not idempotent and has many rough edges and bugs.
The current release is a workable improvement on many fronts:
- zip support is now idempotent (but gtar lacks check-mode)
- New option `exclude` to exclude specific paths/files
- New option `keep_newer` to exclude newer files on target
- New option `extra_opts` to influence unzip/gtar (like synchronize module)
The following items are still ongoing:
- Implement CRC32 support for .zip files
- Re-implement the zip support using native zipfile module
- Re-implement the gtar support using native tarfile/gzip/bz2 modules (lzma external)
- Implement check-mode (works in gzip, but fails using gtar)
- Implement diff-mode (discuss an appropriate output model, like synchronize module)
The re-implementation of unzip/gtar support using native python modules will not only simplify the codebase, additional functionality can be implemented correctly and identically, which is currently not possible. (Other archives could be implemented using native modules equally, incl. options)
* Assorted fixes to zip support (during quality checks)
- Support both rw---- and rwx--- permstr
- Better file type support (more qa needed)
- Symlink support
- Include fix from #3229
* Implement zip diff-mode (itemized change) and avoid changes permissions every time (!)
This commit implements:
- rsync-compatible itemized-change output in diff-mode (using zip)
- no longer changing permissions unconditionally (when idempotent)
* Small fixes to itemized change output
* Fixes to user/group ownership changes
- The implementation of user/group ownership is a bit more complex for idempotency
- We report when a ZIP file incorrectly tags a directory as a file/link
- We only offer diff output when there is a change
* Fix the handling of includes and excludes for unzip
* Remove test output from output (confuses easily)
* Logic and performance improvements to ownership handling, and umask fix
* Handle special files (type '?')
* Make exceptions compatible with python 2.4
* Implement CRC32 support
* Revert some unintended/unknown changes ?
* Taking over maintenance as offered by current maintainer
* Fix support for white-spaces in filenames
* Remove/rename incorrect regex
* Ensure that fat executables end up with execute permission
* Remove check_result from output when unchanged
* When unarchiving as a user, or when owner/group/mode is supplied --diff is insufficient
Only way to be sure is to check request with what is on disk (as we do for zip).
Leave this up to set_fs_attributes_if_different() instead of inducing a (false) change
* By default, don't send confusing check_results in verbose output
This fixes#74.
Without this change, a download failure may bail out with the message:
"Failure downloading http://foo/bar, 'NoneType' object has no attribute 'read'"
whereas with this fix, you'd get a proper error like:
"Failure downloading http://foo/bar, Request failed: <urlopen error [Errno 113] No route to host>"
or one of the many other possible download errors that can occur.
This check will prevent extraction of an archive if the archive does not
actually write to the destination directory but only writes to any writable
sub-directories of it. The underlying tar command will report errors
should it try to write to read-only directories.
Having read the doc for this module several times and completely missing that it can be used for existing remote archives, I propose this update to the wording to make clear from the top the two ways in which this module can be used.
