Streaming Code Worked in v0.2.3 and 0.4.12, fails in 0.10.25

[P. Douglas Reeder]

I can tell the following code executes as far as logging "second piece of index-colorbox.html written", but not to logging "writeUntilBufferFull()".

Any suggestions why the "drain" event doesn't appear to fire under 0.10.25?

writeStream.write("<title>" + title + "</title>\n");

fs.readFile("piece/index-second.html", function (error, buffer) {

//...

writeStream.write(buffer);

console.log("second piece of index-colorbox.html written");

writeStream.addListener("drain", writeUntilBufferFull);

writeStream.write("<table>\n");

});

  

function writeUntilBufferFull() {

var longDate, urlFileName, htmlFileName, row;

console.log("writeUntilBufferFull()   p=", p, "   metadata:", JSON.stringify(pictureMetadata[p]));

//...

}

Have you checked the return values of your `.write()` calls? IIRC you will only see 'drain' if `.write()` returns false.

Yes, on the old platform write() always returned false, so my code was not prepared to deal with a true. :-S

the solution was to, at the end of the callback for readFile, to call writeUntilBufferFull directly.
