NAME

btparser - a backtrace analyzer

SYNOPSIS

btparser [option]... [FILE]...

DESCRIPTION

btparser is a command line tool that analyzes backtraces produced by GDB and provides their textual representation useful for crash duplication detection.

By default, btparser prints the backtrace tree created by parsing the input file.

OPTIONS

Basic startup options

-V, --version: Displays version of btparser.
-?, --help: Print a help message describing all of btparser’s command-line options.

Actions

-r, --rate: Print a float number between 0 and 1, representing the quality of the backtrace.
-c, --crash-function: Print the name of the function where the program crashed, if it's successfully detected.
-h, --duplicate-hash: Print a short, textual representation of the backtrace, useful for detecting the backtrace duplicates.
-s, --distances: Print Damerau–Levenshtein distances between the backtraces specified on the command line.
-g, --dendrogram: Cluster backtraces by their distance and print an ASCII representation of the dendrogram.
-l, --clusters=LEVEL: Print clusters cut from the dendrogram at the specified level.

Additional options

-i, --stdin: Read input from the standard input rather than file.
-m, --max-frames=FRAMES: When creating optimized backtrace or preparing backtrace for comparison, limit the number of frames to FRAMES. (default 8)
-z, --min-cluster-size=SIZE: When printing clusters, ignore clusters that contain fewer than SIZE objects. (default 2)
-d, --debug: Prints debug information when scanning/parsing the backtrace.
-v, --verbose: Print more output than usual.
