[MS4W-Users] ms4w windows 10

Hi,

I have not found out why this error occurs despite having dealt with it a 
lot.

The application is php intensive at startup, many phps are starting 
concurrently although none of them is time intensive. The phps are accessing 
a database, either Oracle or postgreSQL.
The timeouts decrease in number when the php scripts are called 
synchronously.

I found out early that the problem is not bound solely to php but in some 
way involves both php and Apache.
After noticing that timeout almost always occurs the first time after 
opening the browser ( type of browser does not matter ) I clocked the time 
in both the first php script and in the calling javascript.

Javascript:

kaC2.prototype.GetOrgid = function () {
  "use strict";
  var szURL, myRand, d;
  szURL = myC2.phpDIR + "phpC2LM/C3GetOrgid.php?user=" + myC2.username + 
"&sessid=" + myC2.sessid + "&appl=C3L";
  myRand = parseInt(Math.random() * 999999999999, 10);
  szURL += "&rand=" + myRand;
  d = new Date();
  myC2.time = d.getTime();
  call(szURL, "", myC2.GetOrgidCallback);
};

kaC2.prototype.GetOrgidCallback = function (dbres) {
  "use strict";
  var aa, o, j, i, bb, d;
  d = new Date();
  alert(d.getTime() - myC2.time);

The time in milliseconds between the start of the php script until the call 
returned to javascript was in one case 65270.
The time spent in the php script, however, was just 32 milliseconds.
What went on in the meantime is anybody's guess.

When everything goes ok with this call the time between start and return is 
around 190 milliseconds.

The 'call' function in the javascript above uses the GET method by an 
ordinary XMLHttpRequest.

Everything works fine in Windows 7. This started with Windows 10.

Hi Björn,

You will happy to know that all MS4W development now occurs on Windows
10.  A few months ago I purchased a server dedicated just for MS4W
builds, running Windows 10.

I have not encountered your problem with Windows 10.  But, I have seen
your exact problem before on client's machines - most likely you are in
"dll hell", where a different version of a dll found in your path is
mistakenly used by MS4W (Apache, MapServer or in your case likely
php-cgi.exe).  I bet your test machine runs something like QGIS or
PostGIS/PostgreSQL, and one of those other softwares has a dll that is
older than the dll that is supposed to be used by MS4W.

You can use a tool like Dependency Walker to find which dll's are being
used, for your php-cgi.exe file.  If I had to guess, it would be a
common dll like "libeay32.dll" or "ssleay32.dll" that is causing a
problem.

Since we are speaking of PHP, and I know how important PHP and MS4W is
to your organization (and all of the organizations that are on this
mailing list): I have begun the detailed process of preparations for PHP
7 with MS4W.  In fact PHP 7 requires a recent compiler, in fact the most
recent compiler, so that means I have begun compiling all (over 160)
libraries for the new compiler.  It will be a month-long effort. (the
last time I did this, switching to a new compiler, was in year 2009, and
it was the same big effort over a month, and that effort fueled hundreds
of thousands of free downloads and users for over the next 6 years).

So if your organization can help fund this work, as I know how important
MS4W is to so many out there, please contact me directly.  The changes
that your organization help fund will be available for the whole
community, for years to come.

Thank you for sharing your spatial information with MS4W.

Talk soon,

-jeff
