Title: Getting to Know ColdFusion MX


1
Getting to Know ColdFusion MX
  • Rob Brooks-Bilson
  • Web Technology Manager
  • Author, Programming ColdFusion (OReilly)
  • 05/21/2002 Presented to the MD
    CFUG http//www.cfug-md.org

2
Agenda
  • More than we can cover in 1 hour
  • Getting started
  • Infrastructure changes
  • Deprecated and obsolete tags/functions
  • Language changes
  • New features
  • Resources
  • QA

3
Getting Started
  • Installation Planning
  • System requirements generally greater than CF 5
  • Will only upgrade from CF 5
  • Two installation options
  • Standard
  • Removes CF 5
  • Uses existing web server
  • Stand-alone
  • Uses internal web server
  • Port 8500 by defualt
  • Not recommended for production
  • Many config options in \CFusionMX\runtime\servers\
    default\SERVER-INF\jrun.xml

4
Getting Started
  • Supported Operating Systems
  • Windows
  • 98
  • ME (except CF Enterprise)
  • NT 4
  • 2000
  • XP
  • Linux
  • ReaHat 6.2-7.2
  • SuSE 7.2-7.3
  • Unix
  • Solaris 7, 8
  • UPUX 11.00

5
Getting Started
  • Supported Web Servers
  • CF MX internal web server
  • Apache 1.32x and 2.x
  • IIS 4 and 5
  • Netscape 3.6x
  • iPlanet 4.x and 6.x
  • Zeus 4.1 (Linux SuSE)
  • Not officially supported but it works!
  • WebSite Pro (forthcoming TechNote)

6
Getting Started
  • Nervous about upgrading?
  • Initial install can be done stand-alone,
    allowing you to run CF 5 and CF MX on the same
    server
  • Point both CF 5 and CF MX to the same web root
  • When you are satisfied, you can reconfigure MX to
    use your web server instead
  • Code compatibility analyzer in CF Admin does a
    good job of identifying potential issues

7
Infrastructure Changes - Java
  • ColdFusion MX is completely rewritten in Java
  • Ships with the Sun 1.3.1_03 JRE (1.3.1_01 on
    HP-UX)
  • You can also use the IBM JVM 1.2.2 or later
  • JDBC drivers for most popular databases
  • You can still use ODBC for DBs without JDBC
    drivers
  • J2EE under the hood
  • Now shipping
  • Professional and Enterprise (embedded JRun)
  • Available later this year
  • CF MX for J2EE App Servers
  • JRun (full version)
  • IBM WebSphere
  • BEA WebLogic
  • Sun One

8
Infrastructure Changes - Java
  • CFML is compiled to Java byte code
  • Many operations execute faster than previous
    versions of CF
  • DB operations should perform about the same.
    JDBC is NOT inherently faster than ODBC
  • More access to underlying Java architecture if
    you want it!
  • JSP pages
  • JSP tag libraries
  • Servlets
  • EJBs
  • Class files

9
Infrastructure Changes - Registry
  • CF MX no longer uses the registry (Windows and
    nix) to store config information. Majority is
    now in XML config files
  • The XML is WDDX
  • Located in \CFusionMX\lib
  • Examples
  • Scheduled tasks neo-cron.xml
  • DSN info neo-query.xml
  • Verity info neo-verity.xml

11
Infrastructure Changes - Clustering
  • Hardware load-balancers are no longer supported
    within the CF Admin

    quotes)
  • Between pound signs
  • Nested comments

15
Example Comments
ltCFSET x 1 lt!--- I am valid ---gtgt ltCFSET y
DateFormat(Now(), 'mm/dd/yyyy' lt!--- I'm valid
too ---gt)gt ltCFSET z (1 2lt!--- still valid
---gt)gt ltCF_MyTag VAR"x" lt!--- I'm valid too
---gtgt ltCFOUTPUTgt ylt!---I'm valid as well,
although this looks weird---gt lt/CFOUTPUTgt ltH2gtOp
en the file Comments.cfm to see what I'm
doinglt/H2gt
16
Language Changes Variable Scope Structs
  • New scope structures
  • Variables (local) scope
  • Server
  • Caller (custom tags)
  • Use CFDUMP to see the contents of any of the
    scope structures
  • Be careful when calling variable names that are
    also scope structures such as URL, FILE, etc.

17
Example Variable Scope Structs
ltCFSET VARIABLES.x1gt ltCFSET CALLER.y"test the
caller"gt ltCFDUMP VAR"VARIABLES"gt ltPgt ltCFDUMP
VAR"CALLER"gt ltPgt ltCFDUMP VAR"SERVER"gt
18
Language Changes Variable Names
  • Additional structure changes
  • Compound variable names delimited with periods
    now auto create structures In CF 5 ltCFSET
    Employee.NameJoegt Created a variable called
    Employee.Name In CF MX, it creates a structure
    called Employee and a key called Name with the
    value Employee
  • Auto generated structures like this cant be more
    than 3 levels deep my.var.name

19
Example Auto Generating a Structure
ltCFSET Employee.Name "Joe Blow"gt ltCFSET
Employee.Age "30"gt ltCFDUMP VAR"Employee"gt
20
Language Changes Variables
  • Duplicate URL parameters now come across as a
    comma delimited list of values.
  • ?a2a2 returns 1,2 in MX
  • In CF 5, only the last value is passed
  • Compound expressions can now be evaluated inline
    without the use of the Evaluate()
    function ltCFSET a12gt ltCFSET b(105)32gt

21
Example Duplicate URL Variable Names
ltCFIF IsDefined('URL.a')gt altCFOUTPUTgtURL.alt/C
FOUTPUTgt ltPgt lt/CFIFgt ltCFOUTPUTgt ltA
HREF"CGI.Script_Name?a1a2"gtClick
melt/Agt lt/CFOUTPUTgt
22
Language Changes Dates and Times
  • New Short, Medium, Long, and Full masks in
    DateFormat() and TimeFormat()
  • gg mask (era) is now supported in DateFormat()
  • Date functions support years in the range 100 AD
    9999 AD
  • Two digit years
  • JRE and current locale determine how to process
  • For most locales, two digit years are processed
    relative to the current century.
  • Two digit years are interpreted to within 80
    years before the current date and 20 years after.
  • Exceptions
  • Within 72 years before the current date, and 28
    years after English (Australian), English (New
    Zealand), German (Austrian), German (Standard),
    German (Swiss), Portuguese (Brazilian),
    Portuguese (Standard), Swedish.

23
Example DateFormat()
ltCFSET TheDate Now()gt ltCFOUTPUTgt TheDate
DateFormat(TheDate, 'mm/dd/yyyy') ltPgt These
formats are new in ColdFusion MXltBRgt short
DateFormat(TheDate, 'short')ltBRgt medium
DateFormat(TheDate, 'medium')ltBRgt long
DateFormat(TheDate, 'long')ltBRgt full
DateFormat(TheDate, 'full')ltBRgt lt/CFOUTPUTgt
24
Example TimeFormat()
ltCFSET TheTime Now()gt ltCFOUTPUTgt TheTime
TimeFormat(TheTime,'hhmmss tt')ltPgt ltPgt These
formats are new in ColdFusion MXltBRgt short
TimeFormat(TheTime, 'short')ltBRgt medium
TimeFormat(TheTime, 'medium')ltBRgt long
TimeFormat(TheTime, 'long')ltBRgt full
TimeFormat(TheTime, 'full')ltBRgt lt/CFOUTPUTgt
25
Language Changes - RequestTimeOut
  • RequestTimeOut URL parameter is no longer
    supported in MX
  • Instead, CFSETTING now has a REQUESTTIMEOUT
    parameter
  • Allows you to set timeouts on a page-by-page
    basis
  • Place in your Application.cfm for application
    wide setting
  • You can support legacy code like this ltCFIF
    IsDefined(URL.RequestTimeOut)gt ltCFSETTING
    REQUESTTIMEOUT URL.RequestTimeOutgt lt/CFIFgt

26
Language Changes - CFQUERY
  • TIMEOUT attribute is now in seconds and not
    milliseconds as in CF 5. Also applies to each
    part of query, not the whole operation.
  • CONNECTSTRING attribute is no longer supported
    due to JDBC issues. This means you can no longer
    make DSN-less connections.
  • DNNAME, DBSERVER, PROVIDER, and PROVIDERDSN are
    all obsolete
  • DBTYPE attribute is no longer supported except
    for DBTYPEQuery
  • CF now properly escapes single quotes in values
    passed to CFQUERY

27
Language Changes - Query Objects
  • Query objects created manually (via QueryNew())
    can contain complex data types as individual cell
    values
  • Cant be used for query of queries
  • Cant be saved to DB without first serializing
    compex data types into WDDX or other string
    format
  • Invalid names passed to QueryAddNew() now throw
    an error (CF 5 let them go)

28
Example Query Cell Containing an Array
ltCFSET Colors ArrayNew(1)gt ltCFSET
Colors1"Red"gt ltCFSET Colors2"Silver"gt ltCFSET
Colors3"Blue"gt ltCFSET Products
QueryNew("ProductName, Color, Price,
Qty")gt ltCFSET NewRows QueryAddRow(Products,
2)gt ltCFSET QuerySetCell(Products, "ProductName",
"Widget", 1)gt ltCFSET QuerySetCell(Products,
"Color", Colors, 1)gt ltCFSET QuerySetCell(Products,
"Price", "19.99", 1)gt ltCFSET QuerySetCell(Product
s, "Qty", "46", 1)gt ltCFSET QuerySetCell(Products,
"ProductName", "Thingy", 2)gt ltCFSET
QuerySetCell(Products, "Color", Colors,
2)gt ltCFSET QuerySetCell(Products, "Price",
"34.99", 2)gt ltCFSET QuerySetCell(Products, "Qty",
"12", 2)gt ltCFDUMP VAR"Products"gt
29
Language Changes Query of Queries
  • Improved performance
  • Orders of magnitude for many operations
  • Recommended upper limit for records is now 50,000
    rows. CF 5 was 10,000
  • Column aliases in ORDER BY, GROUP BY, and HAVING
  • Neither MX nor CF 5 support table aliases
  • Full support for LIKE
  • Arbitrary expressions can be
  • Grouped
  • In aggregate functions
  • Additionally, arbitrary functions are allowed in
    aggregate functions

30
Language Changes Query of Queries
  • Upper() and Lower() scalar functions for case
    insensitive matching
  • Addition and subtraction can be performed on DATE
    types
  • Improved error messages
  • ! may be used instead of ltgt for comparisons

31
Language Changes - CFMAIL
  • New SPOOLENABLE attribute two options
  • Yes (default) Copy of message is queued to disk
    until it can be sent. Same behavior as CF 5.
  • No Messages are queued in memory until they can
    be sent
  • GROUP attribute now works correctly

32
Language Changes Binary
  • Binary strings are now represented as byte-arrays
  • You can use standard CF string functions for
    manipulating binary data without having to Base
    64 encode
  • CFDUMP can dump the contents of binary objects,
    or you can use CFLOOP to iterate over the
    byte-array

33
Example Manipulating Binary
ltCFINCLUDE TEMPLATE"_TwosCompToDec.cfm"gt ltCFSET
flnm"d\cfusionmx\wwwroot\cfide\administrator\ima
ges\cfmx.gif"gt ltCFFILE ACTION"ReadBinary"

(TheFile10 256), 8)gt ltH2gtGIF
Dimensionslt/H2gt ltCFOUTPUTgt Width
WidthltBRgt Height HeightltBRgt lt/CFOUTPUTgt ltCFD
UMP VAR"TheFile"gt
34
Language Changes - CFSCRIPT
  • Try/Catch exception handling added
  • Syntax a bit different than CFTRY/CFCATCH
  • Catch statements coded outside Try block
  • No CFCATCH structure. You get to define your own
    to hold error information
  • No CFTHROW or CFRETHROW equivalent
  • For-in loop can now be used to loop over COM
    collections

35
Example Try/Catch in CFScript
ltCFSCRIPTgt try xy1 catch("Expression"
exception) writeOutput("Expression Error "
exception.Message) catch("Any"
exception) writeOutput("General Error "
exception.Message) lt/CFSCRIPTgt
36
Example For-in Loop over COM in CFScript
ltcfscriptgt fso CreateObject("COM",
"Scripting.FileSystemObject") for (i in
fso.drives) WriteOutput(i.DriveLetter
"ltbrgt") lt/cfscriptgt
37
Language Changes Regular Expressions
  • MX Introduces a totally new regular expression
    engine
  • Perl compatible
  • More special characters and escape sequences
  • Case conversion in replacement strings
  • Minimal matching

38
Example Regular Expressions
ltCFSET String"I want to go to to the
park."gt ltCFOUTPUTgt From the CF DocsltBRgt REReplac
eNoCase(String, "(A-Za-z) \1","\1","ALL") lt
Pgt Should beltBRgt ReReplaceNoCase(String,
"\b(a-z) \1", "\1", "All") lt/CFOUTPUTgt
39
Language Changes - Unicode
  • CF MX Supports Unicode!
  • MX supports Java UCS-2 character code values in
    the range 0-65535
  • CF 5 only supported characters in the range 1-255
  • Character set support is a function of the
    underlying JRE
  • Default encoding is UTF-8

40
Language Changes - Unicode
  • CFPROCESSINGDIRECTIVE tag can now set the
    encoding for a page
  • The most common character sets are UTF-8, UTF-16,
    UTF-16BE, UTF-16LE, US-ASCII, and ISO-8859-1
  • You may use any character set supported by your
    JRE
  • Many tags and functions have a new CHARSET
    attribute/prameter
  • CFCONTENT
  • CFFILE
  • CFHTTP
  • ToBase64()
  • ToString()
  • UrlDecode()
  • UrlEncodedFormat()

41
Language Changes LS Functions
  • Locales are defined by your JRE
  • Locales may be different than in CF 5
  • LSEuroCurrencyFormat() now only returns EUR as
    the currency symbol for locales that support it
  • LSCurrencyFormat() does not return EUR as the
    currency symbol for any locale even those
    supporting the Euro
  • There are several other changes to LS functions.
    Consult the CF Docs for more info.

42
Language Changes - Locking
  • Contrary to rumor, CFLOCK is not gone just
    different
  • If you dont lock access to shared scope
    variables (application, session, server), CF MX
    wont experience the memory corruption that could
    occur in previous versions
  • However, race conditions as well as overwriting
    of values can still occur.
  • In many (most?) cases, youll continue to want to
    lock

43
Language Changes - Verity
  • All Tags (CFCOLLECTION, CFINDEX, CFSEARCH)
  • Collection names may now contain spaces
  • New SearchEngine exception type is thrown when an
    error occurs with CFINDEX, CFCOLLECTION, and
    CFSEARCH

44
Language Changes - Verity
  • Changes to CFCOLLECTION
  • ACTION is now required
  • New ACTIONList. Returns query with names of
    all registered collections VDK and K2
  • ACTIONMap is no longer necessary as MX
    automatically detects mapped collections

45
Language Changes - Verity
  • Changes to CFINDEX
  • ACTIONOptimize is obsolete in MX
  • EXTERNAL attribute is no longer necessary as MX
    automatically detects mapped collections. Do not
    use it.

46
Language Changes - Verity
  • Changes to CFSEARCH
  • Now allows fully qualified (absolute) path names
    in the COLLECTION attribute
  • EXTERNAL attribute is no longer necessary as MX
    automatically detects mapped collections. Do not
    use it.

47
Language Changes - Verity
  • New K2 Server functions
  • GetK2ServerDocCount()
  • GetK2ServerDocCountLimit()

  • Can now post raw XML using new XML CFHTTPPARAM
    Type
  • New FIRSTROWASHEADERS attribute solves problem
    with first row in delimited file always being
    lost
  • CFHTTP follows a maximum of 4 redirects. CF 5
    would follow up to 5
  • Response headers return structures when multiple
    keys have same name. CF 5 returned arrays
  • Certain behaviors such as SSL support vary
    depending on your JRE
  • See the Release Notes for more info

49
New Features - Security

    versions of each
  • Flash, JPG, or PNG format (no GIF due to
    licensing issues)
  • More interactive display options than CFGRAPH
  • Multiple series
  • Ability to overlay different chart types
