From 405b86a92aee4f2ddb6710bfe07ff714f2afcfa2 Mon Sep 17 00:00:00 2001 From: Andrew Chow Date: Tue, 6 Jun 2017 17:26:56 -0700 Subject: Replace lcov -r commands with faster way Instead of using lcov -r (which is extremely slow), first use a python script to perform bulk cleanup of the /usr/include/* coverage. Then use lcov -a to remove the duplicate entries. This has the same effect of lcov -r but runs significantly faster --- contrib/filter-lcov.py | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100755 contrib/filter-lcov.py (limited to 'contrib') diff --git a/contrib/filter-lcov.py b/contrib/filter-lcov.py new file mode 100755 index 0000000000..ce2966c43d --- /dev/null +++ b/contrib/filter-lcov.py @@ -0,0 +1,24 @@ +#!/usr/bin/env python3 + +import argparse + +parser = argparse.ArgumentParser(description='Remove the coverage data from a tracefile for all files matching the pattern.') +parser.add_argument('pattern', help='the pattern of files to remove') +parser.add_argument('tracefile', help='the tracefile to remove the coverage data from') +parser.add_argument('outfile', help='filename for the output to be written to') + +args = parser.parse_args() +tracefile = args.tracefile +pattern = args.pattern +outfile = args.outfile + +in_remove = False +with open(tracefile, 'r') as f: + with open(outfile, 'w') as wf: + for line in f: + if line.startswith("SF:") and pattern in line: + in_remove = True + if not in_remove: + wf.write(line) + if line == 'end_of_record\n': + in_remove = False -- cgit v1.2.3
