Nadeem Vawda 33c34da574 Simplify usage of LZMAFile's fileobj support, like with BZ2File. 2012-06-04 23:34:07 +02:00
Nadeem Vawda aebcdba829 Make BZ2File's fileobj support easier to use.
The fileobj argument was added during the 3.3 development cycle, so this change
does not break backward compatibility with 3.2.

Lars Gustäbel b062a2fa17 Issue #13815: Resurrect the ExFileObject class.
After a discussion in the tracker, the decision was made to keep the
ExFileObject class after all as a subclass of io.BufferedReader instead of
removing it completely.

Lars Gustäbel 7a919e9930 Issue #13815: TarFile.extractfile() now returns io.BufferedReader objects.
The ExFileObject class was removed, some of its code went into _FileInFile.

Lars Gustäbel dee45e20f6 Issue #12926: Fix a bug in tarfile's link extraction.
On platforms that do not support (symbolic) links, tarfile offers a
work-around and extracts a link in an archive as the regular file the link is
pointing to. On other platforms, this code was accidentally executed even
after the link had been successfully extracted which failed due to the already
existing link.

Lars Gustäbel 01277d166a Merge with 3.2: Issue #13158: Fix decoding and encoding of base-256 number fields in tarfile.
The nti() function that converts a number field from a tar header to a number
failed to decode GNU tar specific base-256 fields. I also added support for
decoding and encoding negative base-256 number fields.

Lars Gustäbel 2e7ddd374b Issue #12841: Fix tarfile extraction of non-existent uids/gids.
tarfile unnecessarily checked the existence of numerical user and group ids on
extraction. If one of them did not exist the respective id of the current user
(i.e. root) was used for the file and ownership information was lost. (Patch

registry.

  Issue #11224: Improved sparse file read support (r85916) introduced a
  regression in _FileInFile which is used in file-like objects returned
  by TarFile.extractfile(). The inefficient design of the
  _FileInFile.read() method causes various dramatic side-effects and
  errors:

    - The data segment of a file member is read completely into memory
      every(!) time a small block is accessed. This is not only slow
      but may cause unexpected MemoryErrors with very large files.
    - Reading members from compressed tar archives is even slower
      because of the excessive backwards seeking which is done when the
      same data segment is read over and over again.
    - As a backwards seek on a TarFile opened in stream mode is not
      possible, using extractfile() fails with a StreamError.

Raymond Hettinger a63a312a3f Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
keyword-only argument.  The preceding positional argument was deprecated,
so it made no sense to add filter as a positional argument.

Lars Gustäbel 9cbdd75ec5 Add read support for all missing variants of the GNU sparse
extensions. Thus, in addition to GNUTYPE_SPARSE headers, sparse
information in pax headers created by GNU tar can now be decoded.
All three formats 0.0, 0.1 and 1.0 are supported.
On filesystems that support this, holes in files are now restored
whenever a sparse member is extracted.

Lars Gustäbel 331b8002f0 Issue #9065: no longer use "root" as the default for the
uname and gname field.

If tarfile creates a new archive and adds a file with a
uid/gid that doesn't have a corresponding name on the
system (e.g. because the user/group account was deleted) it
uses the empty string in the uname/gname field now instead
of "root". Using "root" as the default was a bad idea
because on extraction the uname/gname fields are supposed
to override the uid/gid fields. So, all archive members
with nameless uids/gids belonged to the root user after
extraction.
