Hi guys,
I have a problem with Zinc, I need to send a huge amount of data (bytes) that
translates to ~50Mb.
When I do something like:
ZnEasy
post: 'http://localhost:15432'
data: (ZnEntity bytes: aHugeByteArray.]
I encounter a ‘ConnectionTimedOut: Data send timed out.’, I attach the stack
trace:
ZdcSocketStream(ZdcSimpleSocketStream)>>flushBytes:startingAt:count:
ZdcSocketStream>>next:putAll:startingAt:

I tried to:
- Augment the client timeout to a huge value (10 mins) but it has no effect:
The data send still goes into timeout, after 10-15 sec
- I replaced the ZnEntity with a ZnMultiPartFormDataEntity, still no luck
I am wondering what else can I do.
Moreover, I discovered there is a #signalProgress: message to signal process.
The following examples do not work, any hint?
################################################################################
Example 1, from the book @ http://zn.stfx.eu/zn/zinc-http-components-paper.html:
UIManager default informUserDuring: [ :bar |
[ ^ ZnClient new
signalProgress: true;
get: 'http://zn.stfx.eu/echo?delay=2' ]
on: HTTPProgress
do: [ :progress | bar value: progress printString. progress resume ] ]
################################################################################
Example 2, from ZnClientTests>>#testProgress works, but not when issuing a POST
request
[ :bar |
bar title: 'Downloading Sources...'.
[
ZnClient new
url:
'http://files.pharo.org/sources/PharoV30.sources';
signalProgress: true;
downloadTo: FileLocator temp ]
on: HTTPProgress
do: [ :progress |
progress isEmpty ifFalse: [ bar current:
progress percentage ].
progress resume ] ] asJob run.
…works but only when using #downloadTo: if you do a #post:contents: or a #get:
as in the example with #get: 'http://zn.stfx.eu/echo?delay=10' no process is
shown. Any hint?
Thanks in advance,
Roberto
