HTTP Header field handling in Zinc
by Udo Schneider July 27, 2013

July 27, 2013

All, Is there a supported way to change the capitalization of HTTP header fields in Zinc? I'm currently running into problems with a websocketpp (https://github.com/zaphoyd/websocketpp) based backend which expects a specifically capitalized Sec-WebSocket-* header field. E.g. Sec-WebSocket-* works, Sec-Websocket-* does not. As far as as I can see Zinc nicely capitalizes HTTP header fields. E.g. even if you provide "Sec-WebSocket-Key" the actual transmitted header is "Sec-Websocket-Key". I know that HTTP specified that header fields are case-insensitive. So problem is clearly on the websocketpp side. I just want to know if I can somehow instruct Zinc to not touch the capitalization to make working with non-compliant backends easier. Thanks, Udo

What exactly is https://github.com/pharo-project about ? It is to test the Monticello Git integration? Give visibility to Pharo? I also see Pharo-VM. Is this the reference repository for the VM? (which used to on Gitorious for the OSX code I know about). Thanks. Phil

Units package
by phil＠highoctane.be July 26, 2013

July 26, 2013

In my application, I need to work with units (which I have to integrate in Seaside-Magritte 3). So, I looked around and after a while found http://www.smalltalkhub.com/#!/~MarcusDenker/Units Tests are green on 2.0 and it looks like it will do what I need. Pretty cool package, worth a chapter somewhere. Is there any doc on this except the code itself? Phil

Your vm is too oldâ¦.
by Norbert Hartl July 25, 2013

July 25, 2013

As I cannot work with the pharo VM right now I'm back to use Eliots Cog. But If I open a more recent image it complains about my vm being to old. What does it really check in order to complain? Some just version string/number parsing? Is it always sever? Norbert

How are you doing your jenkins build scripts?
by Norbert Hartl July 25, 2013

July 25, 2013

I'm close to having ported all of our projects to pharo 2.0. Now I'm asking myself what would be a proper setup to run my jenkins build scripts. With RPackage there are more packages in the system then before and in the jenkins scripts you need to invoke HDTestReport forPackages: #( â¦) In 1.4 I just added them manually. Using 2.0 makes this too cumbersome to deal with. So I need to figure out the amount of tests programmatically. The first I came up with (and that would solve my common use case) is something like myPrefix := 'Emcee-' myPackages := RPackage organizer packages select: [:each| each name beginsWith: myPrefix ]. packagesWithTests := myPackages select: [ :package| package classes anySatisfy: [ :cls| cls includesBehavior: TestCase ] ]. packagesNamedTest := myPackages select: [ :each| each name includesSubstring: '-Tests-' ]. testPackages := packagesWithTests union: packagesNamedTest. packages := myPackages difference: packagesNamedTest. HDTestReport runPackages: (testPackages collect: #name). HDLintReport runPackages: (packages collect: #name) So I like to ask how you guys are doing it. Thanks in advance for your answers. Norbert

[ann] snapshotcello
by Tudor Girba July 24, 2013

July 24, 2013

Hi, Stef and I developed Snapshotcello, a little utility that enables you to freeze a snapshot of a given configuration based on what is already loaded in your current image. The idea is simple. You develop against the latest versions of all packages, and commit your changes for each package. When you are ready for a release, you assemble your image, and generate a snapshot version that can be reloaded later. Here is an example of how it can work to take a snapshot of a development version: Snapshotcello new configurationClass: ConfigurationOfMoose; configurationVersion: #development; publishVersion: '4.8-snapshot' You can find more details here: http://www.tudorgirba.com/blog/snapshotcello-take-a-snapshot-when-you-re-re… You can get the code at: Gofer new smalltalkhubUser: 'girba' project: 'Snapshotcello'; package: 'ConfigurationOfSnapshotcello'; load. (Smalltalk globals at: #ConfigurationOfSnapshotcello) loadDevelopment Cheers, Doru -- www.tudorgirba.com "Every successful trip needs a suitable vehicle."

Testing the OpenCalais web service
by HernÃ¡n Morales Durand July 22, 2013

July 22, 2013

I'm testing the OpenCalais web service. This is a web service which needs an API key to be used (registering takes only 1 minute in http://www.opencalais.com/APIkey) To check the service first I've used a Python script, taken from [1] import httplib2 import json LOCAL_API_KEY = '' # Aquire this by registering at the Calais site CALAIS_TAG_API = 'http://api.opencalais.com/tag/rs/enrich' # Some sample text from a news story to pass to Calais for analysis test_body = """ Some huge announcements were made at Apple's Worldwide Developer's Conference Monday, including the new mobile operating system iOS 5, PC software OS X Lion, and the unveiling of the iCloud. """ # header information need by Calais. For more info see http://www.opencalais.com/documentation/calais-web-service-api/api-invocati… headers = { 'x-calais-licenseID': LOCAL_API_KEY, 'content-type': 'text/raw', 'accept': 'application/json', } # Create your http object http = httplib2.Http() # Make the http post request, passing the body and headers as needed. response, content = http.request(CALAIS_TAG_API, 'POST', headers=headers, body=test_body) jcontent = json.loads(content) # Parse the json return into a python dict print json.dumps(jcontent, indent=4) # Pretty print the resulting dictionary returned. The Python script works fine for me. I have tried to translate the code above, but my version in Pharo 2.0 using Zinc returns "I Read a ZnResponse(415 Unsupported Media Type text/plain 365B)" | httpClient localApiKey | localApiKey := ''. " my API key " httpClient := ZnClient new logToTranscript; url: 'http://api.opencalais.com/tag/rs/enrich'; method: #POST; headerAt: 'x-calais-licenseID' put: localApiKey; headerAt: 'accept' put: 'application/json'; headerAt: 'content-Type' put: 'text/raw'; contents: 'Some huge announcements were made at Apple''s Worldwide Developer''s Conference Monday, including the new mobile operating system iOS 5, PC software OS X Lion, and the unveiling of the iCloud.'. httpClient execute. Additionally the request returns the following message: 'Document conversion error. Please make sure that the content-type (passed through the paramsXML) matches this document contents. [ErrorMessage: com.clearforest.platform.system.CLFRuntimeException: There is no converter for this type of URI "file:/C:/CLFSW/v71/ct/bin/../../../v71/ct/var/dptemp/prvt/228295-app9/dp/papi/data/1374378595643-DF317E60-6634505.asc" ]' From what I could see, a difference is the 'text/raw' content-type is passed in Python's httplib2, but in Zinc is overriding by 'text/plain' it in #acceptEntityDescription: ? Any hints? HernÃ¡n [1] http://www.flagonwiththedragon.com/2011/06/08/dead-simple-python-calls-to-o…

MongoDB open close in production (singleton or not)
by Sabine KnÃ¶fel July 18, 2013

July 18, 2013

Hi, Currently, I create one single Instance of Mongo when starting the Image. | theRoot | theRoot := Mongo default. theRoot open. and use it for all requests. In my development environment that works fine. My question is: is this the right way and will it work for production? Or is it better to create one Mongo instance for each request (and close it after the request)? And, btw: what would happen if I would open many Mongo connections but never close any? Or better one Instance per user session?

development image memory use: 180MB in Pharo 2 vs. 40MB in Pharo 1.4.....
by Paul DeBruicker July 18, 2013

July 18, 2013

I've been developing in the same Pharo2 image for a couple weeks and its now 180MB. I use the same development habits as in Pharo 1.4 but there the image would only be about 40MB. Using SpaceTally I can see that I have 40 MB of Arrays. And 10MB of Bitmaps. 8MB of Floats, Strings, & OrderedCollections. My domain objects comprise about 20MB of the image. Is there a way to check for memory leaks over a long period of time? Thanks Paul
