Re: [Pharo-users] Zinc SSL Exception: decrypt failed code:5

by Sabine Manaa

Hi Sven, thank you for your hints. Indeed, the variable @in of ZdcSecureSocketStream has the string "ZnInvalidUTF8: Illegal leading byte for utf-8 encoding" in its utf-8 variable. Can you tell me, what to add to the pharo code that the encoding is correct/so that is equal to the curl command? comparison of headers: they seem to be equal, also the content type is in both cases 'application/json;charset=UTF-8' The ZnResponse headers: a ZnHeaders( same 'Cache-Control'->#('no-cache, no-store, max-age=0, must-revalidate' 'no-store') same 'Connection'->'close' same 'Content-Type'->'application/json;charset=UTF-8' same 'Date'->'Fri, 27 Feb 2015 20:02:40 GMT' same 'Expires'->'0' same 'Pragma'->#('no-cache' 'no-cache') same 'Set-Cookie'->'crbid=10.1.8.3:49247_mt03.prod.gini.net; path=/' same 'Strict-Transport-Security'->'max-age=31536000 ; includeSubDomains' same 'X-Application-Context'->'0.3:8080' same 'X-Content-Type-Options'->'nosniff' same 'X-Frame-Options'->'DENY' same 'X-Xss-Protection'->'1; mode=block' ) result of curl command at command line < HTTP/1.1 200 OK same < Date: Fri, 27 Feb 2015 17:58:37 GMT same < X-Content-Type-Options: nosniff same < X-XSS-Protection: 1; mode=block same < Cache-Control: no-cache, no-store, max-age=0, must-revalidate same < Pragma: no-cache same < Expires: 0 same < Strict-Transport-Security: max-age=31536000 ; includeSubDomains same < X-Frame-Options: DENY same < X-Application-Context: 0.3:8080 < Cache-Control: no-store < Pragma: no-cache same < Content-Type: application/json;charset=UTF-8 same < Connection: close same < Set-Cookie: crbid=10.1.8.5:49387_mt05.prod.gini.net; path=/ regards sabine 2015-02-27 16:58 GMT+01:00 Sven Van Caekenberghe-2 [via Smalltalk] < ml-node+s1294792n4808353h38(a)n4.nabble.com>: > Sabine, > > > On 27 Feb 2015, at 16:36, Sabine Manaa <[hidden email] > <http:///user/SendEmail.jtp?type=node&node=4808353&i=0>> wrote: > > > > Hi Sven, > > Hi all, > > > > I try to send a curl command (which works at command line) from Pharo. > > I get the error: "SSL Exception: decrypt failed code:5" > > > > The working command line command is: > > > > curl -v -H 'Accept: application/json' -u 'aUser:aPassword' > > 'https://user.xxx.net/oauth/token?grant_type=client_credentials' > > > > the result is something like: > > > {"access_token":"a31xxxa-2a22-4xx6c-938d-2bd3ae4a0629","token_type":"bearer","expires_in":42095,"scope":"write"} > > > > > My current Pharo code is: > > | theZnClient | > > theZnClient := ZnClient new > > systemPolicy ; > > https; > > host: 'user.xxx.net'; > > path: 'oauth/token?grant_type=client_credentials'; > > username: 'aUser' password: 'aPassword'; > > accept: ZnMimeType applicationJson; > > get. > > theZnClient inspect close. > > > > 'aPassword' and 'aUser' and xxx.net was replaced by me for security > reasons. > > > > In Pharo, I get a walkback with the error message > > 'SSL Exception: decrypt failed [code:-5]' > > > > But I see, that the ZdcSecureSocketStream has the correct result > > ({"access_token":...":"write"}) in its collection attribute at > > utf-8 string and at latin1-string > > > > so, the request is done and the result is available but then it fails > here: > > ZdcSecureSocketStream(Object)>>error: > > ZdcSecureSocketStream>>sslException:code: > > ZdcSecureSocketStream>>fillBytes:startingAt:count: in Block: [ ... > > ZdcSecureSocketStream>>fillBytes:startingAt:count: > > ZdcSecureSocketStream(ZdcSimpleSocketStream)>>fillReadBufferNoWait > > ZdcSecureSocketStream(ZdcSimpleSocketStream)>>fillReadBuffer > > > ZdcSecureSocketStream(ZdcOptimizedSocketStream)>>readInto:startingAt:count: > > ZnUTF8Encoder>>optimizedReadInto:startingAt:count:fromStream: > > ZnUTF8Encoder>>readInto:startingAt:count:fromStream: > > > > Sven, I could send you the 'aPassword' and 'aUser' and the url by > private > > message.

The transfer of the book from Pier to Pillar is âin processâ and a bit âstalledâ because of an issue in Pillar. For now, if you can package your code and send it to the mailinglist, I can archive it and someone can pick it up when going through the book. Johan

Loading it in the "broken" image didn't help, however new one works fine so I'll assume it is fixed. Thanks!

Re: [Pharo-users] slow pharo launcher

There was a leak, but was fixed some time ago. If you go into preferences and Enable Development Environment, then you can go to the PharoLauncher repository to load the latest Configuration and see if that resolves the problem. btw, I was going to suggest using Configuration Browser, but the version seems a bit behind. cheers -ben On Sat, Feb 28, 2015 at 12:40 AM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > For anyone that may be experiencing this... > > Yesterday when I got above around 20 images PharoLauncher suddenly started > to load slowly (over 5s instead of 1-2s) and even when I deleted some it > stayed slow, however downloading fresh Pharo 3 image and installing > PharoLauncher it works nicely again even with many images... maybe some > leak somewhere? > > Peter > >

slow pharo launcher

by Peter UhnÃ¡k

For anyone that may be experiencing this... Yesterday when I got above around 20 images PharoLauncher suddenly started to load slowly (over 5s instead of 1-2s) and even when I deleted some it stayed slow, however downloading fresh Pharo 3 image and installing PharoLauncher it works nicely again even with many images... maybe some leak somewhere?

It would be fine if you could have a short look at it. The fact that there is readable text in the buffer of the ZdcSecureSocketStream is good, because it means that things basically work. One reason why this is failing might be that Zn tries to read more than there is available in the stream, when the content-length does not match. Encoding problems could be part of the problem too. Could you compare curl -v or curl -D - output with the request/response headers in Pharo ? Look for content-length and compare that with what it already read or not. Is the connection kept alive ? Also look at content-type and see if there is any charset encoding after application/json.

Re: [Pharo-users] Zinc SSL Exception: decrypt failed code:5

by Sabine Manaa

Hi Sven, Hi all, I try to send a curl command (which works at command line) from Pharo. I get the error: "SSL Exception: decrypt failed code:5" The working command line command is: curl -v -H 'Accept: application/json' -u 'aUser:aPassword' 'https://user.xxx.net/oauth/token?grant_type=client_credentials' the result is something like: {"access_token":"a31xxxa-2a22-4xx6c-938d-2bd3ae4a0629","token_type":"bearer","expires_in":42095,"scope":"write"} My current Pharo code is: | theZnClient | theZnClient := ZnClient new systemPolicy ; https; host: 'user.xxx.net'; path: 'oauth/token?grant_type=client_credentials'; username: 'aUser' password: 'aPassword'; accept: ZnMimeType applicationJson; get. theZnClient inspect close. 'aPassword' and 'aUser' and xxx.net was replaced by me for security reasons. In Pharo, I get a walkback with the error message 'SSL Exception: decrypt failed [code:-5]' But I see, that the ZdcSecureSocketStream has the correct result ({"access_token":...":"write"}) in its collection attribute at utf-8 string and at latin1-string so, the request is done and the result is available but then it fails here: ZdcSecureSocketStream(Object)>>error: ZdcSecureSocketStream>>sslException:code: ZdcSecureSocketStream>>fillBytes:startingAt:count: in Block: [ ...
