tuning apache for large subversion repos

Filed under: Programming,Server Admin — dh @ 11:09 am

I kept getting very aggravating timeout issues when trying to reintegrate a branch back into the trunk of one of our large subversion repositories. Tuned apache’s httpd.conf with the following and the problems disappeared.

# Timeout: The number of seconds before receives and sends time out.
Timeout 60000

# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection).
KeepAlive On

# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
MaxKeepAliveRequests 0

# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
KeepAliveTimeout 60000

.NET consume a php nusoap web service server *or* PHP NuSOAP Document/Literal Web Service Server

Filed under: Programming — dh @ 11:16 am

Ripped blatently from here so that I might not ever lose this information again!

PHP NuSOAP Document/Literal Web Service Server

If you are using regular Pear SOAP, it doesn’t work in document/literal. I tried. So I turned to NuSOAP, which unfortunately has very little in the way of documented examples, especially in document/literal. I am including the server that worked for me (discovered largely through trial and error), as well as a test client. This is designed to mirror Pear SOAP as much as possible (since I was converting from one to the other). Note: document/literal in NuSOAP does not verify data types, so int, string, boolean, etc. are all converted to strings between the client and server.



$server = new soap_server;
$server->configureWSDL('servicename', 'urn:servicename','','document');

array('in' => array('Name' => 'xsd:string',
'Age' => 'xsd:int'),
'out' => array('Pass' => 'xsd:boolean')

//if in safe mode, raw post data not set:
if (!isset($HTTP_RAW_POST_DATA)) $HTTP_RAW_POST_DATA = implode("\r\n", file('php://input'));

function myRegister(&$server,$methodname,$params)
'urn:servicename', // namespace
$server->wsdl->endpoint.'#'.$methodname, // soapaction
'document', // style
'literal', // use
'N/A' // documentation

function DoSomething($Name,$Age)
if ($Name=="mleiv" && $Age==35) $result=true;
return array('Pass'=>$result);



$client = new soapclient('http://localhost/wherever/SOAPServer.php?wsdl','wsdl');
if ($client->getError())
print "<h2>Soap Constructor Error:</h2><pre>".
$result = $client->call("DoSomething",array("parameters"=>$params),$ns);
if ($client->fault) //soap_fault
print "<h2>Soap Fault:</h2><pre>(".$client->fault->faultcode.") ".
elseif ($client->getError())
print "<h2>Soap Error:</h2><pre>".$client->getError()."</pre>";
print "<h2>Result:</h2><pre>".$result["Pass"]."</pre>";
print '<h2>Details:</h2><hr />'.
'<h3>Request</h3><pre>' .
htmlspecialchars($client->request, ENT_QUOTES) . '</pre>'.
'<h3>Response</h3><pre>' .
htmlspecialchars($client->response, ENT_QUOTES) . '</pre>'.
'<h3>Debug</h3><pre>' .
htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';

What the heck is 1.8189894035459E ?

Filed under: Programming — dh @ 3:53 pm

I have been pulling what little hair I have out for the past hour trying to figure out a very peculiar thing that was happening to me in php. I was doing some math and a function that I know was supposed to return 0 was returning 1.8189894035459E . If you called the function outside of a loop it worked fine, but is you called it in a while loop for instance, it would return this crazy value. All I had to do was to typecast the result of the integer addition to an (int) and the problem went away. Hope this might help someone in the future save some hair.

Dump one MySQL database to another MySQL database

Filed under: Programming,Server Admin — dh @ 1:28 am

mysqldump -u[uname] -p[password] [table] | mysql -u[uname] -p[password] –host=[ip address] -C [table]

I.E.: mysqldump -umy_user_name -pmy_secret_password foo_table | mysql -umy_2nd_user_name -pmy_2nd_secret_password –host= -C foo_table

(whole command should be on one line of course.) 🙂

PHP, OpenSSL and ftp_ssl_connect() on Win32, my journey…

Filed under: Programming,Server Admin — dh @ 1:46 pm

I need to compile php for Windows so that the ftp_ssl_connect function would be available. This is how I did it. All of this is as of today, May 19, 2008. Windows XP Pro SP2.

  • Download & Install (this is a large install > 1GB):
    » Microsoft Visual C++ 2008 Express Edition
    » Windows SDK for Windows Server 2008 and .NET Framework 3.5
  • Copy C:\Program Files\Microsoft SDKs\Windows\v6.1\Include\WinResrc.h to C:\Program Files\Microsoft SDKs\Windows\v6.1\Include\winres.h
  • Create the directory C:\work
  • Download:
    » php 5.2.6 Source Code and extract it to the C:\work\ folder.
  • Download:
    » Needed Libraries ( Edin Kadribašic has a nice zip file with everything in it. You need to go into subfolder /php/win32 and click on (If this link is down try this one: ). Create folder C:\work\php_build\ and extract the zip file into it.
  • Download:
    » Newer libxml2. The libxml package that is included in the zip file was a little out of date. Download this one and extract the contents of the zip file on top of C:\work\php_build\ . Overwrite files as needed.
  • Download & Install:
    » Win32 OpenSSL (Win32 OpenSSL v0.9.8g)
  • Patch php source:
    As of php 5.2.6, you will need to patch C:\work\php-5.2.6\ext\ftp\ftp.c in your php source directory. deciacco did some awesome work in producing a working patch. You can see his site here. You can download my patched version for php 5.2.6 here. Just replace the copy of ftp.c in your C:\work\php-5.2.6\ext\ftp\ folder.
  • Open:
    Start > Program Files > Visual C++ 9.0 Express Edition > Visual Studio Tools > Visual Studio 2008 Command Prompt
  • Type these commands into the Visual Studio 2008 Command Prompt:
    Link To Commands
    You will see many, many compile warnings. This is quite normal. 🙂
  • If everything went well, you should now have php.exe in the folder C:\work\Release_TS\ which has ftp_ssl_connect functionality.

    PHP Back Button in I.E.

    Filed under: Programming — dh @ 1:35 pm

    Man this was giving me a problem for awhile. After using session_start( ); on my pages, the back button was suddenly giving me the “Warning: Page has Expired The page you requested was created using information you submitted in a form…” crap. I added header(“Cache-control: private”); directly after the session_start( ); and now everything works great!!

    IE Bug: One Text Input / Enter Key Doesn’t Submit

    Filed under: Programming — dh @ 10:34 pm

    Here is the fix to this quirky and aggravating bug. If you only have one input text box and you want to submit the form by pressing the enter key, IE will simply refresh the current page for you! Simply add this hidden text input between your form tags and the form will submit as expected!

    <input type="text" style="visibility:hidden;display:none;" name="dummy"></input>
