5. Testing Guidelines

+

To be filled.

+
+

5.1. Testplan for releases

+

Explain release numbers. major, minor. developer releases. etc.

+
    +
  1. +

    Remove any existing rpm with rpm -e

    +
    2. +
  2. +

    Remove any file that was left over. This includes (but is not limited to)

    +
      +
    • +

      /var/log/privoxy

      +
      • +
    • +

      /etc/privoxy

      +
      • +
    • +

      /usr/sbin/privoxy

      +
      • +
    • +

      /etc/init.d/privoxy

      +
      • +
    • +

      /usr/doc/privoxy*

      +
      • +
    +
    3. +
  3. +

    Install the rpm. Any error messages?

    +
    4. +
  4. +

    start,stop,status Privoxy with the specific script (e.g. + /etc/rc.d/init/privoxy stop). Reboot your machine. Does autostart work?

    +
    5. +
  5. +

    Start browsing. Does Privoxy work? Logfile written?

    +
    6. +
  6. +

    Remove the rpm. Any error messages? All files removed?

    +
    7. +
+
+
+

5.2. Fuzzing Privoxy

+

To make fuzzing more convenient, Privoxy can be configured with --enable-fuzz which will result in the --fuzz + option becoming available.

+

Example (tested on ElectroBSD):

+ + + + +
+ 
# Compile Privoxy with instrumentation for afl
+$ export CC=afl-clang
+$ export CFLAGS="-fsanitize=address -ggdb"
+$ export CPPFLAGS=-I/usr/local/include/
+$ export LDFLAGS="-fsanitize=address -L/usr/local/lib"
+$ export AFL_USE_ASAN=1
+$ export AFL_HARDEN=1
+$ ./configure --with-debug --enable-extended-host-patterns --enable-accept-filter --enable-no-gifs --enable-compression --enable-strptime-sanity-checks --enable-external-filters --enable-fuzz

5.2. Test reports
Please submit test reports only with the test form
-at sourceforge. Three simple steps:
-        
  • Select category: the distribution you test on.
  • Select group: the version of Privoxy that we are about to release.
  • Fill the Summary and Detailed Description with something
-              intelligent (keep it short and precise).

-        Do not mail to the mailing list (we cannot keep track on issues there).

+Privoxy version 3.0.24 (http://www.privoxy.org/)
+Usage: ./privoxy [--config-test] [--chroot] [--help] [--no-daemon] [--pidfile pidfile] [--pre-chroot-nslookup hostname] [--user user[.group]] [--version] [configfile]
+       ./privoxy --fuzz fuzz-mode ./path/to/fuzzed/input [--stfu]
+
+Supported fuzz modes and the expected input:
+ action: Text to parse as action file.
+ client-request: Client request to parse. Currently incomplete
+ client-header: Client header to parse.
+ chunked-transfer-encoding: Chunk-encoded data to dechunk.
+ deflate: deflate-compressed data to decompress.
+ filter: Text to parse as filter file.
+ gif: gif to deanimate.
+ gzip: gzip-compressed data to decompress.
+ pcrs-substitute: A pcrs-substitute to compile. Not a whole pcrs job! Example: Bla $1 bla C $3 blah.
+ server-header: Server header to parse.
+ server-response: Server response to parse.
+
+The following fuzz modes read data from stdin if the 'file' is '-'
