  • Myspace flash player blocked

    Myspace music players (the flash music player) doesn't work on Privoxy 3.0.10, because it is blocking lads.myspacecdn.com: Aug 05 15:11:09.531 Privoxy(7f8fc4450910) Request: lads.myspacecdn.com/videos/Main.swf crunch!

  • Comment: "=" should be allowed on booleans

    By the way, a minor consequence of the fact that "=" is not valid on BOOLEANs is that the output from "stp -p" is not actually valid STP. Example input: x : BOOLEAN; ASSERT(x); QUERY(FALSE); If you run "stp -p" on this input, you get: Invalid. ASSERT( x = TRUE ); However the latter line of the output is not valid STP syntax. A consequence is that you can't just take the output...

  • Optimization makes STP run slower

    I have discovered some cases where STP runs faster with its optimizations disabled. STP's help says that the command-line flag "-a" disables optimizations. However on these inputs, I found that "stp -a" runs very quickly (under 1 second), while plain "stp" seems to run forever (at least an hour). Surely this can't be intentional -- can it? I attach four closely related test cases...

  • No documentation for BOOLEAN operators

    The STP documentation lists information about operators for manipulating BITVECTORs and ARRAYs but not for BOOLEANs. For instance, it does not list AND, OR, NAND, NOR, XOR, , =>, etc. It might be nice to have documentation of this.

  • "=" should be allowed on booleans

    STP doesn't allow one to use the "=" binary operator on booleans. Example input: x : BOOLEAN; ASSERT(x = TRUE); QUERY(FALSE); and the output from STP: syntax error: line 2 syntax error, unexpected '=' Fatal Error: The prohibition on use of "=" for booleans is confusing and unexpected. It might be a bit more user-friendly to accept "=" on booleans. The simplest workaround...

  • "stp -p" outputs non-constant counterexample

    "stp -h" suggests that "stp -p" will print a counterexample, if the input formula is Invalid. But, running "stp -p" on the following input: x, t : BOOLEAN; ASSERT(t x); ASSERT(x); QUERY(FALSE); yields the following output: Invalid. ASSERT( x = t ); ASSERT( t = TRUE ); This is not what I wanted to see. It is not a valid counterexample. A counterexample should provide a...

  • "make regressall" fails

    The INSTALL file suggests that you can test STP by running make regressall This does not work, on the latest version checked into Subversion. I get the following error message: *** Error: WARNING: cannot find testcase ../../stp-tests/test: no such file or directory.

  • Look for config options in a separate file, for RPM updates

    It would be nice if Privoxy's configuration files were set up to work better with RPM updates. I use Privoxy on Fedora Linux, via the RPM that Fedora ships. I configure Privoxy by manually editing the files in /etc/privoxy, specifically, /etc/privoxy/config (to add forward-socks4a lines) and /etc/privoxy/user.action. However each time Fedora makes available an updated Privoxy RPM that...

  • Comment: Pyzor with SA gives internal error

    Any chance of someone looking into this? I too am getting this error with Spamassassin.

  • read_key_file() doesn't check retval from read()

    read_key_file() contains this code (excerpted): size = read (fd, in.data, in.capacity); if (size == in.capacity) msg (M_FATAL, "Key file ('%s') can be a maximum of %d bytes", file, (int)in.capacity); cp = (unsigned char *)in.data; while (size) { const unsigned char c = *cp; ... ++cp; --size; } There is no check to see whether the...
