multithreading - How do I write an asynchronous C extension to Tcl? -

-

I have a C function that I would like to make available to Tcl. The thing is, I want to make calls from TCL asynchronous in the same fashion: Thread :: Send, ie? -Sync? And? Vernamus? Flags

I do not asynchronous C API understanding of TCL, and how to use it it can not find any examples. The C, I can create a thread to work, but do not know how to handle how the signal to set the variable specified by Warnm place in the thread how to signal when it is finished, and Tcl command is.

For this problem, I use another process would not be able to use a simple asynchronous solution TCL side, such as a pipe, TCL threads, or library that COM. The reason for this is that C call loads are allocated in a large data structure, and other C calls that come in front of TCL (which is out of necessity) that the structure was allocated in the same thread as Tcl Interp. .

Any assistance will be highly appreciated.

Write the easiest way C code is synchronous with a simple API, and client data structures, associated with orders or an interpreter to all states if possible, or failing to use thread-specific data call to then use the thread package, other threads these utility Threads Allow for, and wrap that creates inside the TCL code The API looks natural and that (lightly) hides how you go about implementing APIs. Which is very easy to do.

You can also use TCL because the thread package is actually only one wrapper. (It communicates by sending events between actually threads; see the definition in the thread package for a burstful description.) Or, if you are actually doing I / O only, then you write your code to asynchronous I / O and Failivent / access to use Notifier system to work to work just simple ways above and Tcl code and existing packages Rather than are more complex.

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
