We are going to publish impala-shell release 4.1.0a1 on PyPi. This patch upgrades following three python libraries which are used for generating egg files when building impala-shell tarball. upgrade bitarray from 1.2.1 to 2.3.0 upgrade prettytable from 0.7.1 to 0.7.2 upgrade thrift_sasl from 0.4.2 to 0.4.3 Updates shell/packaging/requirements.txt for the versions of dependent Python libraries. Testing: - Ran core tests. - Built impala-shell package impala_shell-4.1.0a1.tar.gz, installed impala-shell package from local impala_shell-4.1.0a1.tar.gz, verified impala-shell was installed in ~/.local/lib/python2.7/site-packages. Verified the version of installed impala-shell and dependent Python libraries as expected. - Set IMPALA_SHELL_HOME as ~/.local/lib/python2.7/site-packages/ impala_shell, copied over egg files under installed impala-shell python package so we can run the end-to-end unit tests against the impala-shell installed with the package downloaded from PyPi. Passed end-to-end impala-shell unit tests. - Verified the impala-shell tarball generated by shell/make_shell_tarball.sh.

Contributing to bitarray
The bitarray type is very stable and feature complete at this point,
which means that pull requests to bitarray/_bitarray.c will most likely
be rejected, unless they improve readability and performance.
There may be room for improvements/additions in the bitarray.util module,
added in the 1.2.0 release. However, due to the slow release cycle of this
package, it may be more practical to create your own library which depends
on bitarray. This is completely possible, even on the C-level. Please
study the implementation of bitarray/_util.c for details. In particular for
C extensions to work with the bitarray type, it is important that
the bitarrayobject struct is defined in the same way:
typedef struct {
PyObject_VAR_HEAD
char *ob_item; /* buffer */
Py_ssize_t allocated; /* allocated buffer size (in bytes) */
Py_ssize_t nbits; /* length of bitarray, i.e. elements */
int endian; /* bit endianness of bitarray */
int ob_exports; /* how many buffer exports */
PyObject *weakreflist; /* list of weak references */
} bitarrayobject;
/* member endian may have these values */
#define ENDIAN_LITTLE 0
#define ENDIAN_BIG 1
These essential (as well as other useful) declarations can be found
in bitarray/bitarray.h.
