Re: CF10 creating extra CFID/CFTOKEN cookies at the domain level

2014-10-02 Thread John Pullam

Some more info:

- I have not issued a setclientcookies=yes so assuming that is the default it 
should be there.

- the redirect is via an htaccess file which says 

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

- I think the redirect is not relevant because I am doing the testing and I am 
only using www.

- Multiple browsers have shown up with the duplicate cookies and the 
duplication seems to occur after a logon (using my own app code). I don't use 
any specific URLs ... all are relative based on the domain.

Any other thoughts on what is causing it?

Why this regex takes so long?

2014-10-02 Thread Claude Schnéegans

Hi, I'm having a problem with a scheduled task that chokes my server.
Its role is to analyse bounced messages.
I have been able to identify where it blocks, when analysing a line like this 
one with the regex below:
Message-id: 26823262.22036.1411993378646.JavaMail.NS4007563$@127.0.0.1
CFSET regEx = 
[A-Za-z0-9_](\.?[A-Za-z0-9_\-]+)*@[A-Za-z0-9_\-\.]+(\.[A-Za-z]{2,6})
The server seems to get stuck in an infinite loop.
Actually, the problem is that the function REfind takes much too long.

I narrowed the problem to the following code which shows that the time taken 
grows exponentially with the number of characters and is anyway abnormaly long :

CFSET line=00$@
CFSET regEx = ([A-Z0-9]+)*@
CFLOOP INDEX=n FROM=1 TO=10
   CFSET line = 0  line
   CFSET deb=getTickCount()
   CFSET result = REFindNocase (regEx, line)
   CFSET time = (getTickCount()-deb)/1000
   CFOUTPUT
   line = (#len(line)# char. = #line#
   result = #result# in #time# sec.BR/CFOUTPUT
/CFLOOP

And the result is:
line = (17 char. = 000$@ result = 17 in 0.055 sec.
line = (18 char. = $@ result = 18 in 0.028 sec.
line = (19 char. = 0$@ result = 19 in 0.063 sec.
line = (20 char. = 00$@ result = 20 in 0.113 sec.
line = (21 char. = 000$@ result = 21 in 0.224 sec.
line = (22 char. = $@ result = 22 in 0.447 sec.
line = (23 char. = 0$@ result = 23 in 0.902 sec.
line = (24 char. = 00$@ result = 24 in 1.787 sec.
line = (25 char. = 000$@ result = 25 in 3.574 sec.
line = (26 char. = $@ result = 26 in 7.192 sec.

Re: Getting memory amount used

2014-10-02 Thread Claude Schnéegans

 Might be able to get this using Java.

Thanks, I'll dig into this.
I thought that my server chokes because of lack of memory, but I finally found 
that it was because of an infinite time taken in a regExp analysis.
I just dropped a post about this.

Re: Why this regex takes so long?

Think this has something to do with the Regex itself. I stink at them;
however try plugging it in here:

It returns something about catastrophic backtracking.

You may want something like this: [A-Z0-9]*@

Re: Why this regex takes so long?

2014-10-02 Thread Claude Schnéegans

 however try plugging it in here:

It gives me the same result:
Timout for PHP and Python (after about 3 sec)
and a result in Javascript in about 4 sec, because it happens in my computer 
and there is no time out.
It looks like the problem is really in the regEx itself.

I'll try to get another one.

CF11 Licensing - 2 servers behind load balancer

Okay, if I have a single site, being run on two or more virtual (vmware)

does one license cover the site?

IANAL - As I understand it if one server is just failover then you only need 
one license. If both servers are active then you need two.

If you are having to do regular restarts for server stability then there is 
definitely something wrong. At CF Webtools we have work with a large number of 
clients on CF10 that have very high load websites. None of them need regular 
restarts anymore. We are experts at rooting out server configuration issues as 
well as coding practices that may not be efficient that can cause problems. 

There are numerous blog posts on performance tuning for ColdFusion 10 JVM, 
Tomcat IIS connectors and code. Some of those are at my blog 
(http://www.trunkful.com) or at the ColdFusion Muses blog 
(http://coldfusionmuse.com/). Adobe has many blog posts too on server

Re: CFML restart ACF 10 app server service

2014-10-02 Thread Claude Schnéegans

 None of them need regular restarts anymore.

If you do need restart, it could be because you have a problem in your code.
I have a task scheduled every 2 hours, it scans mail rebounces with regular 
expressions
and who knows why, after one year with no problem, I recently got a certain 
string that completely blocked the server.
I had to restart the server at least once every day.
I changed a little bit the reg exp, and now it works like a charm.
Now, could a regular expression taking so long be considered as a problem with 
ColdFusion?

Re: CFML restart ACF 10 app server service

2014-10-02 Thread Russ Michaels

we have been using FR for years.
The primary issue we have on shared servers is hung database queries, which
causes all coldfusion requests to be used up until there are none left, and
cf will then stop serving up pages to any new requests.
There are so many things that can cause this, especially on a shared
server, but the problem is that a query is a native java call, so cannot be
killed even by FusionReactor, so it will just hang around forever until CF
is restarted,
Diagnosing and performance tuning takes time and costs money, and on a
shared server, no-one is going to pay for that, so it would be an endless
and cost prohibitive task.
These specific types of issues on affect coldfusion due to the fact it runs
as a service, PHP and the likes do not suffer from such issues.

You should have a real of the following article I wrote on this topic which
explains the problems with CF on shared hosting:

  so just to clarify, these are servers with hundreds of different websites
  and customers on right ? not just 1 client/app per server? which is easy
 to
  tune

  If you are having to do regular restarts for server stability then there
  is definitely something wrong. At CF Webtools we have work with a large
  number of clients on CF10 that have very high load websites. None of
 them
  need regular restarts anymore. We are experts at rooting out server
  configuration issues as well as coding practices that may not be
 efficient
  that can cause problems.
 
  There are numerous blog posts on performance tuning for ColdFusion 10
 JVM,
  Tomcat IIS connectors and code. Some of those are at my blog (
  http://www.trunkful.com) or at the ColdFusion Muses blog (
  http://coldfusionmuse.com/). Adobe has many blog posts too on server
  performance and tuning. I highly recommend using these resources to see
 if
  you can resolve the root cause(s) for the server stability issues.
 
  *Shameless plug* Or contact us and we can help you.

  except we rarely had any such issues with cf4/5, it ran like a dream
  compared to CF6+, which is down to java

  we have a scheduled task setup to restart CF every morning. Since we
  have
  done this we have hardly any cf issues any more.
 
  Wow! How far we have come, he says with great sarcasm, it harkens back
  to
  the good old CF4 on NT server days.
