32 <p>Explain release numbers. major, minor. developer releases. etc.</p>
35 <p>Remove any existing rpm with rpm -e</p>
38 <p>Remove any file that was left over. This includes (but is not limited to)</p>
41 <p>/var/log/privoxy</p>
47 <p>/usr/sbin/privoxy</p>
50 <p>/etc/init.d/privoxy</p>
53 <p>/usr/doc/privoxy*</p>
58 <p>Install the rpm. Any error messages?</p>
61 <p>start,stop,status <span class="APPLICATION">Privoxy</span> with the specific script (e.g.
62 /etc/rc.d/init/privoxy stop). Reboot your machine. Does autostart work?</p>
65 <p>Start browsing. Does <span class="APPLICATION">Privoxy</span> work? Logfile written?</p>
68 <p>Remove the rpm. Any error messages? All files removed?</p>

74 "APPLICATION">Privoxy-Regression-Test</span></a></h2>
75 <p>If you compiled, packaged or merely installed Privoxy, it is recommended to run <span class=
76 "APPLICATION">Privoxy-Regression-Test</span> to verify that at least the tested parts of <span class=
77 "APPLICATION">Privoxy</span> are working as expected.</p>
78 <p>This is actually pretty easy. For details, please see <b class="COMMAND">perldoc

82 <h2 class="SECT2"><a name="FUZZING" id="FUZZING">5.3. Fuzzing Privoxy</a></h2>
83 <p>To make fuzzing more convenient, Privoxy can be configured with --enable-fuzz which will result in the --fuzz
84 option becoming available.</p>
85 <p>Example (tested on ElectroBSD):</p>
86 <table border="0" bgcolor="#E0E0E0" width="100%">
89 <pre class="PROGRAMLISTING"># Compile Privoxy with instrumentation for afl
91 $ export CFLAGS="-fsanitize=address -ggdb"
92 $ export CPPFLAGS=-I/usr/local/include/
93 $ export LDFLAGS="-fsanitize=address -L/usr/local/lib"
94 $ export AFL_USE_ASAN=1
96 $ ./configure --with-debug --enable-extended-host-patterns --enable-accept-filter --enable-no-gifs --enable-compression --enable-strptime-sanity-checks --enable-external-filters --enable-fuzz
99 Privoxy version 3.0.24 (http://www.privoxy.org/)
100 Usage: ./privoxy [--config-test] [--chroot] [--help] [--no-daemon] [--pidfile pidfile] [--pre-chroot-nslookup hostname] [--user user[.group]] [--version] [configfile]
101 ./privoxy --fuzz fuzz-mode ./path/to/fuzzed/input [--stfu]
103 Supported fuzz modes and the expected input:
104 action: Text to parse as action file.
105 client-request: Client request to parse. Currently incomplete
106 client-header: Client header to parse.
107 chunked-transfer-encoding: Chunk-encoded data to dechunk.
108 deflate: deflate-compressed data to decompress.
109 filter: Text to parse as filter file.
110 gif: gif to deanimate.
111 gzip: gzip-compressed data to decompress.
112 pcrs-substitute: A pcrs-substitute to compile. Not a whole pcrs job! Example: Bla $1 bla C $3 blah.
113 server-header: Server header to parse.
114 server-response: Server response to parse.
116 The following fuzz modes read data from stdin if the 'file' is '-'
119 chunked-transfer-encoding

131 $ echo '$1 bla fasel $2' > input/pcrs
