[GRASS-dev] I've tripled GRASS's I/O speed

[Seth Price]

Hi, I've spent the last two or three hours trying to get GRASS' unit tests
running. With a fresh source tree, the best I can get is ~9% of the tests
passing:

seths-mbp:grass-7.1.svn_src_snapshot_2015_09_19 sprice$ grass71 --text
../nc_spm_08_grass7/PERMANENT/

[...]

GRASS 7.1.svn
(nc_spm_08_grass7):/usr/local/grass/grass-7.1.svn_src_snapshot_2015_09_19 >
python -m grass.gunittest.main --location
/usr/local/grass/nc_spm_08_grass7/ --location-type nc

test_g_list from ./general/g.list failed (1 test failed)

test_g_remove from ./general/g.remove failed (2 tests failed)

test_overwrite from ./general/g.rename failed (3 tests failed)
[...]

test_vto3d from ./vector/v.to.3d failed (1 test failed)

test_vwhat_layers from ./vector/v.what failed (1 test failed)

test_vwhat_ncspm from ./vector/v.what failed (4 tests failed)


Executed 127 test files in 0:00:55.959398.

>From them 12 files (9%) were successful and 115 files (91%) failed.

GRASS 7.1.svn

I'd really like to work on these unit tests. Any ideas as to where I'm
going wrong? I feel like I've exhausted the various knowledge bases
available online.
Thanks,
Seth
