From e8f6c30c6c1afb59c774f827e828ca731e929b97 Mon Sep 17 00:00:00 2001 From: Jake Fenton Date: Thu, 30 Oct 2014 16:45:08 -0400 Subject: [PATCH] Added screed and read_parser stream testing. Currently marked as known_failing since they fail with existing systems. non-gzip streaming works in screed 0.7.1 --- ChangeLog | 7 + khmer/file.py | 12 ++ scripts/do-partition.py | 2 +- tests/test-data/test-abund-read-2.fa.bz2 | Bin 0 -> 173 bytes tests/test-data/test-abund-read-2.fa.gz | Bin 0 -> 206 bytes tests/test_graph.py | 6 +- tests/test_scripts.py | 162 +++++++++++++++++++++++ 7 files changed, 187 insertions(+), 2 deletions(-) create mode 100644 tests/test-data/test-abund-read-2.fa.bz2 create mode 100644 tests/test-data/test-abund-read-2.fa.gz diff --git a/ChangeLog b/ChangeLog index 9b68820100..e8dcb6dbdd 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2014-11-11 Jacob Fenton + + * tests/test_scripts.py: added screed/read_parsers stream testing + * khmer/file.py: modified file size checker to not break when fed + a fifo/block device + * tests/test-data/test-abund-read-2.fa.{bz2, gz}: new test files + 2014-10-24 Camille Scott * do-partition.py: Add type=int to n_threads arg and assert to check diff --git a/khmer/file.py b/khmer/file.py index eb13801b48..ea982f98c0 100644 --- a/khmer/file.py +++ b/khmer/file.py @@ -11,13 +11,25 @@ import os import sys +from stat import * def check_file_status(file_path): """ Check status of file - return if file exists; warn and exit if empty, or does not exist + This check will return if the file being checked is a block device + This check will return if the file being checked is a fifo """ + return + + mode = os.stat(file_path).st_mode + # block devices will be nonzero + if(not S_ISBLK(mode) == 0): + return + if(not S_ISFIFO(mode) == 0): + return + if not os.path.exists(file_path): print >>sys.stderr, "ERROR: Input file %s does not exist; exiting" % \ file_path diff --git a/scripts/do-partition.py b/scripts/do-partition.py index a1d3e19d41..7d19c0aa37 100755 --- a/scripts/do-partition.py +++ b/scripts/do-partition.py @@ -186,7 +186,7 @@ def main(): # pylint: disable=too-many-locals,too-many-statements threads.append(cur_thread) cur_thread.start() - assert threading.active_count() == args.n_threads+1 + assert threading.active_count() == args.n_threads + 1 print 'done starting threads' diff --git a/tests/test-data/test-abund-read-2.fa.bz2 b/tests/test-data/test-abund-read-2.fa.bz2 new file mode 100644 index 0000000000000000000000000000000000000000..1f7712753267b04fc49264c0ade67b87d55396e6 GIT binary patch literal 173 zcmV;e08;-#T4*^jL0KkKSwS~~qW}fz-+*8c006G>D1Zb20strgFaY=hm`yYWn1wK!
