Description: ------------ I noticed that on several of my machines sitting behind a proxy server I was unable to use PEAR...I get errors like this: bash:/tmp$ sudo pear search Net Invalid xml downloaded from "http://pear.php.net/rest/p/packages.xml": XML Error: 'Not well-formed (invalid token)' on line '1' bash:/tmp$ However on other machines things seemed to be working ok. The difference turned out to be that the machines having trouble were sitting behind a DeleGate 9.5.6 proxy server. I sniffed some packets and DeleGate is returning a valid response--but it's using chunked encoding (e.g. a "Transfer- Encoding: chunked" HTTP header) in the response. This seems to throw PEAR for a loop....I modified REST.php to see what the content it was attempting to parse was like so: bash:/tmp$ diff -u /tmp/REST.php.original /usr/share/php/PEAR/REST.php --- /tmp/REST.php.original 2010-10-28 12:09:12.000000000 - 0400 +++ /usr/share/php/PEAR/REST.php 2010-10-28 11:55:14.000000000 -0400 @@ -139,7 +139,7 @@ PEAR::popErrorHandling(); if (PEAR::isError($err)) { return PEAR::raiseError('Invalid xml downloaded from "' . $url . '": ' . - $err->getMessage()); + $err->getMessage() . $content); } $content = $parser->getData(); case 'text/html' : bash:/tmp$ The output is attached--notice that the output here still has the chunk delimiters in it. Because those chunk delimiters are still present, the XML is invalid and can't be parsed. I've also attached a .pcap showing the packet sniff taken from the transfer PEAR attempted to do. I don't believe that the proxy server is at fault here--e.g. what it's returning is valid and it does specify to the useragent that it's sending it via chunked encoding, but PEAR apparently doesn't handle the encoding properly. As a temporary workaround, users could modify REST.php to use HTTP/1.0 instead of HTTP/1.1 as this eliminates chunked encoding. I've used this successfully as a temporary measure. The necessary modifications are just two lines in REST.php as follows: bash:/tmp$ diff -u /tmp/REST.php.original /usr/share/php/PEAR/REST.php --- /tmp/REST.php.original 2010-10-28 12:09:12.000000000 - 0400 +++ /usr/share/php/PEAR/REST.php 2010-10-28 12:15:12.000000000 -0400 @@ -328,9 +328,9 @@ } if (isset($proxy['host'])) { - $request = "GET $url HTTP/1.1\r\n"; + $request = "GET $url HTTP/1.0\r\n"; } else { - $request = "GET $path HTTP/1.1\r\n"; + $request = "GET $path HTTP/1.0\r\n"; } $request .= "Host: $host\r\n"; bash:/tmp$ Test script: --------------- pear search Net Expected result: ---------------- bash:/tmp$ sudo pear search Net Retrieving data...0% ....50%....Matched packages, channel pear.php.net: ======================================= Package Stable/(Latest) Local Date_Holidays_Netherlands 0.1.2 (alpha) Driver based class to calculate holidays in the Netherlands.
