btparser: a backtrace analyzer


btparser - a backtrace analyzer


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


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.


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


-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.
