encoding and decoding. There are bunches of places where we don't want to invest in a full fuzzer, but we would like to make sure that some string operation can handle all its possible inputs. This fuzzer uses the first byte of its input to decide what to do with the rest of the input. Right now, all the possibilities are decoding a string, and seeing whether it is decodeable. If it is, we try to re-encode it and do the whole thing again, to make sure we get the same result. This turned up a lot of bugs in the key-value parser, and I think it will help in other cases too. Closes ticket 28808.
The scripts directory holds tools for use in building, generating, testing, and maintaining the Tor source code. It is mainly for use by developers. Code maintenance scripts ------------------------ maint/checkLogs.pl -- Verify that Tor log statements are unique. maint/check_config_macros.pl -- Look for autoconf tests whose results are never used. maint/checkOptionDocs.pl -- Make sure that Tor options are documented in the manpage, and that the manpage only documents real Tor options. maint/checkSpaces.pl -- Style checker for the Tor source code. Mainly checks whitespace. maint/findMergedChanges.pl -- Find a set of changes/* files that have been merged into an upstream version. maint/format_changelog.py -- Flow the changelog into the proper format. maint/redox.py -- Find places that should have DOCDOC comments to indicate a need for doxygen comments, and put those comments there. maint/updateVersions.pl -- Update the version number in the .nsi and windows orconfig.h files. Testing scripts --------------- test/chutney-git-bisect.sh -- a git bisect run script that bisects using chutney. The script builds tor and tor-gencert, then runs chutney. The script takes optional arguments for out-of-tree builds, and specific chutney network flavours. You should copy this script before using it with git bisect, so that it doesn't change (or disappear) during bisection. test/cov-blame -- Mash up the results of gcov with git blame. Mainly useful to find out who has been writing untested code. test/cov-diff -- Compare two directories of gcov files to identify changed lines without coverage. test/coverage -- Generates a directory full of gcov files. You need to use this script instead of calling gcov directly because of our confusingly named object files. test/scan-build.sh -- Example script for invoking clang's scan-build static analysis tools. Code generation scripts ----------------------- codegen/gen_linux_syscalls.pl -- Generate a table mapping linux syscall numbers to their names. codegen/gen_server_ciphers.py -- Generate a sorted list of TLS ciphersuites for servers to choose from. codegen/get_mozilla_ciphers.py -- Generate a list of TLS ciphersuites for clients to use in order to look like Firefox. Code transformation scripts --------------------------- coccinelle/calloc.cocci -- Transform code to replace variants of malloc(a*b) with calloc(a,b)
