NAME

6       btparser - a backtrace analyzer
7

SYNOPSIS

9       btparser [option]... [FILE]...
10

DESCRIPTION

12       btparser  is  a  command line tool that analyzes backtraces produced by
13       GDB and provides their textual representation useful for crash duplica‐
14       tion detection.
15
16       By  default,  btparser prints the backtrace tree created by parsing the
17       input file.

31       Actions
32
33       -r, --rate
34              Print  a  float number between 0 and 1, representing the quality
35              of the backtrace.
36
37       -c, --crash-function
38              Print the name of the function where  the  program  crashed,  if
39              it's successfully detected.
40
41       -h, --duplicate-hash
42              Print  a  short, textual representation of the backtrace, useful
43              for detecting the backtrace duplicates.
44
45       -s, --distances
46              Print Damerau–Levenshtein distances between the backtraces spec‐
47              ified on the command line.
48
49       -g, --dendrogram
50              Cluster  backtraces  by their distance and print an ASCII repre‐
51              sentation of the dendrogram.
52
53       -l, --clusters=LEVEL
54              Print clusters cut from the dendrogram at the specified level.
55
56
57       Additional options
58
59       -i, --stdin
60              Read input from the standard input rather than file.
61
62       -m, --max-frames=FRAMES
63              When creating optimized backtrace  or  preparing  backtrace  for
64              comparison, limit the number of frames to FRAMES. (default 8)
65
66       -z, --min-cluster-size=SIZE
67              When  printing clusters, ignore clusters that contain fewer than
68              SIZE objects. (default 2)
69
70       -d, --debug
71              Prints debug information when scanning/parsing the backtrace.
