That sounds great. I don't have a Website so here are
my CF8 enhancements notes. Hope some of this is new
for you guys. Sorry about the formatting.
New CF8 Items
precisionEvaluate() - used for exact math mathical
evalutions when precision is critical.
ListToArray() - Now has a Boolean attribute that
allows to include empty elements.
<cfinterface> - new tag can only contain cffunction.
Interface provides a contract between two interfaces.
Function does not contain any body. Performance cost
is negligible.
IsInstanceOf(comp, type) - new function.
getComponentMetadata - returns meta data of
component/instance without instantiation.
Huge CFC performance - up to 20x faster
Serializable
CFC store in the session can be retrieved back on
failover in cluster.
CFC referencing a CFC also supported
OnMissingMetho() callback to component
Missing method signature available in the callback
Handle errors
Handle all getxxx and setXXX calls without defining
those methods.
OnMissingTemplate callback to application
Function invoked on file not found condition.
OnMissing Template(URL)
Per Application Settings
Mappings
Custom tag paths
Via THIS scope n Application.cfc
Overrides server wide settings in application.cfc
Multi-threading
Allows you to run multiple tasks in parallel
New threads can run asynchrounous to the page
Can be used when
Lot of independent tasks that need not be
synchronous
Lot of tasks for which the user need not be made
wait.
Inter-thread communications
Join - current thread waits for another thread to
finish
Termincate
A cfthread can terminate another cfthread
Data exchange in thread scope
Shared scope thread
Only owner can write to it
Accessed using thread name
Also contains thread metadata
Can live much beyond the request thread
Name of thread must be uniques in the request
Like a function it has its own scope
Can access all scopes and its variables
Cfoutput inside the thread body will not write to the
page response
Output goes into a buffer in the thread scope
Any error in the thread does not affect the request
Neew file I/O
File I/O works on stream
Read/write is done in chunk instead of the entire
file.
Filereadline() allows you to read the file line by
line
FileIsEOF() - tells you when you have reached the end
of the file.
This is much like other languages.
You can now specify how many characters to read at a
time.
Fileread() - new
Filewrite() - new
Filecopy() - new
FileMove() - new
FileeDelete() - new
FilesetAttribute() - new
FileSetAccessmode() - new
GetFileInfo()- new
DB enhancements
Aut-Generated key retrieval
Transaction Save points
<DBINFO> used to obtain:
Tables in data source
CFDUMP enhancements
Show or hide query columns
Include SQL and other metadata when dumping query
objects
<CFZIP> tag to handle zip/jar files
Secure FTP support
Fileupload
A file of any size can be uploaded to the server now
Struct returned by getHTTPRequestData() will not have
any content if called in request in which a file is
uploaded.
