On line 357, why do you call assert()? An invalid byte should throw an exception, not assert and dump core.

I meant line 367.

review: Needs Fixing

[Matthias Brantner (matthias-brantner)]

Once you finished the implementation of the transcoding stream buffer, I don't even want to do this check anymore. This must not happen with the stream buffer.

I don't understand how it "must not happen." It can always happen. However, I think you're saying that you assume the check will happen in the transcoder. While it will be doing checks, bad input can still happen.

In the mean time, using an assert() is still too Draconian.

[Matthias Brantner (matthias-brantner)]

I have replaced the assertion with a graceful error.

Is there an example that works with streaming?
I wasn't able to make the following work:
import module namespace http = "http://www.zorba-xquery.com/modules/http-client";

declare namespace h = "http://expath.org/ns/http-client";

let $item := http:send-request(<h:request href="https://stream.twitter.com/1/statuses/sample.json?delimited=length"
                                          method="GET"
                                          username="wcandillon"
                                          password="wnvbb86g"
                                          override-media-type="text/plain"
                               />
                               ,
                               "https://stream.twitter.com/1/statuses/sample.json?delimited=length",
                               ()
                                )[2]
for $tweet in tokenize($item,"a")
return $tweet

Where:
import module namespace http = "http://www.zorba-xquery.com/modules/http-client";

declare namespace h = "http://expath.org/ns/http-client";

let $item := http:send-request(<h:request href="https://stream.twitter.com/1/statuses/sample.json?delimited=length"
                                          method="GET"
                                          username="wcandillon"
                                          password="wnvbb86g"
                                          override-media-type="text/plain"
                               />
                               ,
                               "https://stream.twitter.com/1/statuses/sample.json?delimited=length",
                               ()
                                )[2]
return $item

streams fine.
What am I missing?

[Matthias Brantner (matthias-brantner)]

As discussed in this thread, only the new tokenize function of the string module streams.
Use the following instead

import module namespace s = "http://www.zorba-xquery.com/modules/string";

s:tokenize($item, "a")

[William Candillon (wcandillon)]

Works like a charm.
