Base64MimeConverter class>>mimeDecodeToBytes: change breaks image load
by Alistair Grant March 16, 2018

March 16, 2018

Hi Guille & Pavel, On 6 Feb Guille changed Base64MimeConverter class>>mimeDecodeToBytes: so that it doesn't reset the dataStream position back to the start of the stream. This breaks Pavel's PlayingCard, part of FreeCell (you can see that I only load important stuff :-)). PlayingCard class>>initialize "PlayingCard initialize" | forms f | "Read the stored forms from mime-encoded data in imageData." f := Base64MimeConverter mimeDecodeToBytes: (ReadStream on: self imageData). forms := OrderedCollection new. f next = 2 ifFalse: [self error: 'corrupted imageData']. [f atEnd] whileFalse: [forms add: (Form new readFrom: f)]. ... Previously, f would be at the start of the stream (which makes sense given this usage), but now it is at the end of the stream, so returns nil and "f next = 2" fails. Guille, can you explain the change. The commit log just says "make tests run". Note that a lot of users of this won't fail as they just call #contents of the stream after #mimeDecodeToBytes:, which works regardless of the current position. Thanks, Alistair

FileHandle creates a buffered stream on a buffered stream
by Sven Van Caekenberghe March 16, 2018

March 16, 2018

Hi (Guille), FileHandle creates a buffered stream on a buffered stream when sent #readStream. Note how #binaryReadStream adds a bufferer stream as well as #readStreamEncoded: Probably the latter should not do this Sven

Something is happening...
by Marcus Denker March 16, 2018

March 16, 2018

Hi, There is something odd happeningâ¦ or better: There is *a lot* happening. Just one example: for the Newsletter, the original idea was to send out once a month a post with 3 things, some of them recycled (e.g. pointers to existing projects, re-use âsuccess storiesâ, things like that. Now already some months ago I had to add âand here are some other interesting announcements, blog posts, videosâ. But this month, the list of things for the newsletter TODO list contains over 60 entries. With the exception of maybe 5, these are just things that happened between sending the February newsletter and today. Newsletter March should be ready till this thursday, I hope, subscribe or read the oder ones here: http://newsletter.pharo.org <http://newsletter.pharo.org/> Marcus

Pharo 7 new file stream encoders
by Thierry Goubier March 16, 2018

March 16, 2018

Hi all, how does one create a file stream in Pharo 7 that forces a specific line end convention ? For example, for forcing all end of lines to be Character lf. The old way, fileStream lineEndConvention: #'lf'. does not work anymore. Thanks, Thierry

Hi Everyone, If I download a recent Pharo 64 bit image, e.g.: http://files.pharo.org/image/70/latest-64.zip And use a Pharo VM from commit: commit 4749358b5717b9a2f7e1d44f9baac48ed5d80431 Author: Eliot Miranda <eliot.miranda(a)gmail.com> Date: Wed Mar 7 15:11:21 2018 -0800 or later, the following will reliably crash the VM: ./pharo Pharo7.0-64bit-a26248b.image eval "OCBytecodeGeneratorTest run: #testExample2" Earlier VMs don't crash.

New ConfigurationOfZincHTTPComponents
by Sven Van Caekenberghe March 14, 2018

March 14, 2018

Just a quick heads up: there is a new ConfigurationOfZincHTTPComponents with a version 2.9.1 (based on a new baseline 2.9), not yet declared stable. [ In the Zn MC repos ] This version contains the changes made recently by Guille to streams in Pharo 7. It should be possible to load this version in various Pharo versions without breaking anything fundamental. However, the CI is not yet happy and I don't yet know why, hence I hesitate to declare this a stable version. I will try to figure this out tomorrow. === Name: ConfigurationOfZincHTTPComponents-SvenVanCaekenberghe.113 Author: SvenVanCaekenberghe Time: 14 March 2018, 8:55:19.156462 pm UUID: ebb9d97d-c623-0d00-bd15-c17e09f900fd Ancestors: ConfigurationOfZincHTTPComponents-SvenVanCaekenberghe.112 new 2.9 baseline and 2.9.1 version, not yet declared stable incorporates pharo 7 stream changes by Guille ter === Sven
