I'm having an issue in the logs I cannot replicate on the browser. I'm getting hundreds of these per day
invalid component definition, can't find component [cfc.udf]
The cfc are stored in a cfc folder one level above the app. This is so that many apps can use the same cfc.
Folder structure:
---- cfc
--------- udf.cfc
---- myApp
--------- application.cfc
In the application.cfc, I'm using application-specific mappings because this is set on a lot of different load-balanced-servers in production as well as a QA environment and local testing environment and keeping them all synced would be difficult.
At onRequestStart, I have a function that restarts the application every 5 minutes. It was supplied by a consultant. I suspect that this is the culprit because the logs show these errors coming in at exactly 5 minute intervals
<cfcomponent>
<cfset This.name = "myApp">
<cfset This.Sessionmanagement=true>
<cfset This.Sessiontimeout="#createtimespan(0,0,30,0)#">
<cfset this.mappings['/cfc'] = ExpandPath('../cfc')>
<cffunction name="onApplicationStart">
<cfset Application.udf = createObject("component", "cfc.udf").init()>
</cffunction>
<cffunction name="onRequestStart">
<cfset appRefreshMinutes = 5>
<cfif Not IsDefined("Application.refreshTime")>
<cfset currentMinute = Minute(Now())>
<cfset Application.refreshTime = DateAdd("n", -(currentMinute MOD appRefreshMinutes)+appRefreshMinutes, Now())>
<cfset Application.refreshTime = DateAdd("s", -(Second(Application.refreshTime)), Application.refreshTime)>
</cfif>
<cfif Now() GTE Application.refreshTime Or IsDefined("URL.reload")>
<cflock name="ApplicationInit" type="exclusive" timeout="5" throwontimeout="false">

Promoted from the comments
Have you tried using a mapping name other than /cfc? Like:
<cfset this.mappings['/somethingelse'] = ExpandPath('../cfc')>
so that you can then call it like:
<cfset Application.udf = createObject("component", "somethingelse.udf").init()>
Maybe it just looks odd to me or maybe that is causing your issue (cfc being a reserved word or somehow getting special treatment in this case).

We've migrated a ColdFusion application from ColdFusion 10 to ColdFusion 2016. After Migration, Application variables are not staying in its scope, it is refreshing on each and every request.
Consider the following example,
Application.cfm
<cfsetting enablecfoutputonly="true" />
<CFAPPLICATION NAME="Test App"
SETCLIENTCOOKIES="YES"
CLIENTMANAGEMENT="YES"
SESSIONMANAGEMENT="YES"
SESSIONTIMEOUT="#CREATETIMESPAN(0,8,0,0)#"
APPLICATIONTIMEOUT="#CREATETIMESPAN(1,0,0,0)#">
<cfdump var="#Application#" label="app">
<CFLOCK SCOPE="APPLICATION" TYPE="EXCLUSIVE" TIMEOUT="10">
<CFSET Application.Email = "test#test.com">
<CFSET Application.DataSource="test">
</cflock>
Test.cfm
<CFLOCK SCOPE="APPLICATION" TYPE="READONLY" TIMEOUT="10">
<cfset Application.one = 1>
<cfset Application.two = 2>
<cfset Application.three = 3>
</cflock>
OnRequestEnd.cfm
<cfsetting showdebugoutput="false" />
<cfdump var="#Application#" label="onRequestEnd">
So if we request /test.cfm
it'll throw the following output
Again refreshing the page also giving the same output
Not sure why the Application scoped variables are losing its persistence.
the following is the expected output..
Any idea of Why the application variables are lost and getting refreshed on each and every request ?
I haven't tested this code, but what you're seeing is the procedural order of operation performed by Application.cfm. You're essentially redefining the application on every request, which is why on the name exists in your initial dump and the rest exist on the dump in onRequestEnd.
If you update your code to use Application.cfc, you can ditch the cflock code, better organize your "triggers" and define your application variables once, when needed, using onApplicationStart.
<cfcomponent>
<cfset this.name = "Test App">
<cfset this.SETCLIENTCOOKIES="YES">
<cfset this.CLIENTMANAGEMENT="YES">
<cfset this.SESSIONMANAGEMENT="YES">
<cfset this.SESSIONTIMEOUT="#CREATETIMESPAN(0,8,0,0)#">
<cfset this.APPLICATIONTIMEOUT="#CREATETIMESPAN(1,0,0,0)#">
<cfsetting enablecfoutputonly="true" />
<cffunction name="onApplicationStart" access="public" returnType="void" output="false">
<cfset application.Email = "test#test.com">
<cfset application.DataSource="test">
</cffunction>
<cffunction name="onRequestStart" access="public" returntype="boolean" output="false">
<cfset application.one = 1>
<cfset application.two = 2>
<cfset application.three = 3>
<cfreturn true>
</cffunction>
<cffunction name="onRequestEnd" access="public" returntype="boolean" output="false">
<cfsetting showdebugoutput="false" />
<cfdump var="#application#" label="onRequestEnd">
<cfreturn true>
</cffunction>
</cfcomponent>
This should define email and datasource in the application scope one time, when the app first loads. The variables one, two and three will be created at the start of each request, but you can add a check to set them only if they don't already exist.
You can then use child Application.cfc files to help modularize your application using sub-folders and sub-application specific variables. They'll still exist in the scope of the larger application, but you'll be able to manage them from a location specific to a sub-app this way.
I have one .cfc that I use for all communication between client and server code. This cfc page has about 10 different function. Each function has different purpose and I have queries for Select, Insert, Update and Delete. I'm wondering if I should set timeout on the top of the .cfc page inside cfcomponent tag or this should be set inside of the each function or do I even need this? In our current system we have some many error messages like: The request has exceeded the allowable time limit Tag: CFQUERY.
I would like to prevent any similar error messages in my app. Here is example of my cfc page:
<cfcomponent>
<cfset currentDate = DateFormat(Now(),'mm/dd/yyyy')>
<cfset currentTime = TimeFormat(Now(),'hh:mm tt')>
<cfinvoke component="appEntry" method="getRecord" returnvariable="CHKAccess">
<cfinvokeargument name="user" value="userdata"/>
<cfinvokeargument name="app" value="myApp"/>
</cfinvoke>
<cfset adminAccess = false>
<cfset userAccess = false>
<cfif CHKAccess.RecordCount EQ 1>
<cfif CHKAccess.pd_hfmAccess EQ 'A'>
<cfset adminAccess = true>
</cfif>
<cfif CHKAccess.pd_hfmAccess EQ 'U'>
<cfset userAccess = true>
</cfif>
</cfif>
<cffunction name="getData" access="remote" output="true" returnformat="JSON">
<cfargument name="keyVal" type="string" required="true">
<cfset fnResults = structNew()>
<cfif userAccess>
<cfquery name="getRec" datasource="tes">
SELECT some columns
FROM Test
</cfquery>
<cfset fnResults.status = "200">
<cfelse>
<cfset fnResults.status = "400">
<cfset fnResults.message = "Invalid access attempt.">
</cfif>
<cfreturn fnResults>
</cffunction>

</cfcomponents>
If anyone have suggestion what would be the best fix please let me know. Thank you.
You should set the requesttimeout in the method that contains that long-running cfquery.
You don't want to "punish" all methods for just one method. If you set it for all, how do you know which one is slow and which one is okay, unless you don't care?
I have an existing ColdFusion application in my server. What I needed is a duplicate of that application. What I did was copy the entire folder of the original application and put it into another folder.
I already edited the Application.cfm and the links across all the pages in my copy. However, .../indexc.cfm?page=a_app_checklist - in this case, the a_app_checklist is not being updated even if I changed everything on my server /Copy/pages/app/a_app_checklist.cfm
I tried to upload the updated a_app_checklist.cfm on the original application and from there, it was updated. What should I do because I want my copy of the application to be a stand-alone from the original application.
Here is a part of my Application.cfm code:
<cfapplication name="Applicationv2" sessionmanagement="yes" setclientcookies="yes" sessiontimeout="#CreateTimeSpan(00,00,30,00)#"
applicationtimeout="#CreateTimeSpan(00,01,00,00)#" clientstorage="cookie" loginstorage="session">

<cfset Application.initialized = "yes">
</cfif>
</cflock>
<cfscript>
Application.System.LogActivity("Name","IP","Application scope variables initialized.");
</cfscript>
</cfif>
Like I said, the "page" part in the URL are the only ones that are not being updated. Does it mean I have problems with my URL.Page initialization?
Please let me know if you need additional code. I appreciate any input about this question. Thank you in advance! I am still learning ColdFusion and I will appreciate it if you will help me understand what I need to know!
My application pulls lots of data from different applications according to the selected scopes. For e.g. Org level and SubOrg level scopes, this can cause to bring server down and everyday causes server crashing and timeouts.
So I wanted to know whether wrapping cfthread around my cfhttp will solve my timeout problem?
<cfinclude template="fundedScopes.cfm">
<!--- Call the funded scopes --->
<cfset dynVarName = "funded" & bizforShort>
<cfif structKeyExists(variables,dynVarName)>

UPDATED CODE TO LATEST ITERATION
The following function consumes a webservice that returns address details based on zip code (CEP). I'm using this function to parse the xml and populate an empty query with the address details. I would like to know if there is a more elegant way to achieve the same result. It seems to be a waste to create an empty query and populate it...
Any ideas could my method be modified or the code factored/simplified?
<!--- ****** ACTION: getAddress (consumes web-service to retrieve address details) --->
<cffunction name="getAddress" access="remote" returntype="any" output="false">
<!--- Defaults: strcep (cep (Brazilian zip-code) string webservice would look for), search result returned from webservice --->
<cfargument name="cep" type="string" default="00000000">
<cfset var searchResult = "">
<cfset var nodes = "">
<cfset var cfhttp = "">
<cfset var stateid = 0>
<cfset var tmp = structNew()>
<!--- Validate cep string --->
<cfif IsNumeric(arguments.cep) AND Len(arguments.cep) EQ 8>
<cftry>
<!--- Consume webservice --->
<cfhttp method="get" url="http://www.bronzebusiness.com.br/webservices/wscep.asmx/cep?strcep=#arguments.cep#"></cfhttp>
<cfset searchResult = xmlparse(cfhttp.FileContent)>
<cfset nodes = xmlSearch(searchResult, "//tbCEP")>
<!--- If result insert address data into session struct --->
<cfif arrayLen(nodes)>
<cfset tmp.streetType = nodes[1].logradouro.XmlText>
<cfset tmp.streetName = nodes[1].nome.XmlText>
<cfset tmp.area = nodes[1].bairro.XmlText>
<cfset tmp.city = nodes[1].cidade.XmlText>
<cfset tmp.state = nodes[1].uf.XmlText>
<cfset tmp.cep = arguments.cep>
<!--- Get state id and add to struct --->
<cfset stateid = model("state").findOneByStateInitials(tmp.state)>
<cfset tmp.stateid = stateid.id>
<cfreturn tmp>
</cfif>
<!--- Display error if any --->
<cfcatch type="any">
<cfoutput>
<h3>Sorry, but there was an error.</h3>
<p>#cfcatch.message#</p>
</cfoutput>
</cfcatch>
</cftry>
</cfif>
</cffunction>
<!--- ****** END ACTION getAddress --->
The calling code:
<!--- Get address data based on CEP --->
<cfset session.addressData = getAddress(cep=params.newMember.cep)>
I can't test this because I don't have an example XML file / CEP to test with, but here is a minor rewrite that addresses four things:
Instead of using cfparam and some strange "params" structure, you should pass the CEP into the function as an argument.
The function shouldn't directly modify session data. Instead, you should return the result and let the calling code assign it to the session (or wherever else it might be needed). I'll show this in a 2nd code example.
Cache the xml result per CEP -- assuming this doesn't change often. (You'll have to improve it further if you want time-based manual cache invalidation, but I can help add that if necessary)
Don't use StructInsert. It's not necessary and you're just writing it the long way for the sake of writing it the long way. There is no benefit.
Again, this isn't tested, but hopefully it's helpful:
<cffunction name="getAddress" access="remote" returntype="any" output="false">

<!--- Validate cep string --->

</cfif>
</cfif>
<!---
<!--- Redirect to page two of the sign up process --->
<cfset redirectTo(controller="assine", action="perfil")>
--->
</cffunction>
Notice that I commented out the redirect you had at the end. That's because with my function, you'll be returning a value, and the redirect should be done after that, like so:
<cfset session.addressData = getAddress("some-CEP-value") />
<cfset redirectTo(controller="assine", action="perfil")>
If you're going to leave out the caching (As you say in a comment you will), then here is a version that makes no attempt at caching:

<cfset tmp.state = nodes[1].uf.XmlText />
<cfset tmp.cep = arguments.cep />
<!--- Get state id and add to struct --->

<cfset tmp.stateid = stateid.id />
</cfif>
<cfreturn duplicate(tmp) />
<!--- Display error if any --->
<cfcatch type="any">

</cfif>

--->
</cffunction>
Note that I did leave in the use of duplicate(). What this does is return a duplicate of the object (in this case, the struct). This is much more important when you start to work on applications where you're passing complex values into and out of functions over and over again. Using duplicate() causes things to be passed by value instead of by reference. It may not bite you in this case, but it's a good habit to get into.
I would also still use the function argument and return a value -- but it's arguable that this is my personal preference. In a way it is. I believe that a function should be fully encapsulated; a total "black box". You give it some input and it gives you back some output. It should not modify anything outside of itself. (Again, just my opinion.)
So assuming you're using this function as part of a larger multi-step process, you should still use it the same way I've described above. The only difference is that you're setting the session variable outside of the function body. Just as previously:
<cfset session.addressData = getAddress("some-CEP-value") />
<cfset redirectTo(controller="assine", action="perfil")>
That looks pretty straightforward. CF doesn't (yet?) have any magical XML-to-Query functions, but that would be pretty cool. If you wanted, you could probably write up an XSL transform to go from XML to WDDX so that you could use the cfwddx tag ... but that's probably putting the cart before the horse.
You need to move your arrayLen() if block into the try block. As it stands, if the cfhttp tag throws an error, the nodes variable will be a string and not an array, thus causing the arrayLen() to throw another error.
Minor nitpick: I wouldn't add a row to the query until inside the arrayLen() block. That way, the calling code can check recordCount to see if the result was a success.
Beyond that ... that's pretty much how it's done.
