Re: [Pharo-users] Huge image

David, I don't have a direct solution, but I have been playing with an analysis technique for solving this particular type of problem: scads of Strings and a need to "make sense of the reference graph". If you look at this example[1], you'll see that there are 202K instances of String (this example is from a GemStone db). the nodes pointing to the String node, show that of the 202K strings, there are 70K instances of Array referencing one or more of the 202k strings; 47K instances of MCVersionInfo and 43K MethodVersionRecord instances. I've found that this approach can help you understand why you have so many strings ... The basic technique is to gather the instances of String, then for each instance of string, gather the collection of objects that reference the String instance and summarize the reference by class instance count and keep an IdentitySet of the instances referencing Strings by class so that you can build the next level of references .... For GemStone, this information is displayed using Roassal2 and the calculations are done by scanning a backup of the repository... You could probably brute force calculate this in Pharo (be sure to isolate the objects that you are using in your analysis from the set of objects being analyzed otherwise things get out of control ...

Huge image

by Davide Varvello

Guys, I've a bloated image and I don't know why it's so huge and how to shrink it. It happened that my image has grown from 50MB to 440MB in a morning. I've already followed these suggestions https://github.com/pharo-project/pharo-core/wiki/Memory-Hogs and flushing monticello repos the image reduced itself to 219MB, better. Anyway I don't know how to reduce it more. Evaluating: SmalltalkImage current reportCPUandRAM I found you can see ByteStrings occupy 85.5% of space! I tried to inspect instances of ByteString, but I can't find anything worth of. If I Open pointers to the instance I find references to GLMPanePort, GLMPane and NodeModel (see attached png) I'm on Pharo 4 TIA Davide <http://forum.world.st/file/n4876854/huge_image.png> -- View this message in context: http://forum.world.st/Huge-image-tp4876854.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

If I take the same example with widgetA and widgetB, when trying to reach previous sub-widgets with the focus, I can only access the first button of each sub-widget is it normal? How can I fix this?

Re: [Pharo-users] How to generate "Content-Type: application/octet-stream" with Zinc client

by Sven Van Caekenberghe

>From your netcat output I inferred that you wanted two content-type headers, but I don't think you do, I guess you just want to control the content-type. When creating a ZnPart based on a file, the content-type is inferred automatically from the filename's extension. The simplest solution is to use an unknown file type, like .bin or .dat which will result in a content-type of application/octet-stream (the default). ZnMimePart fieldName: 'file' fileNamed: '/tmp/foo.bin'. You could try setting the content-type after creation. | part | part := ZnMimePart fieldName: 'file' fileNamed: '/tmp/foo.txt'. part headers contentType: ZnMimeType default. part. The methods #setContentType: could be added to ZnMimePart, I guess. > On 10 Feb 2016, at 13:42, chicoary <chicoary(a)gmail.com> wrote: > > Thanks Sven for your reply. > > The curl I want reproduce with Zinc is: > > curl 'http://localhost:5001/api/v0/add?stream-channels=true' \ > -H 'content-type: multipart/form-data; > boundary=a831rwxi1a3gzaorw1w2z49dlsor' \ > -H 'Connection: keep-alive' \ > --data-binary $'--a831rwxi1a3gzaorw1w2z49dlsor\r\nContent-Type: > application/octet-stream\r\nContent-Disposition: file; name="file"; > filename="file.txt"\r\n\r\nfile.txt > contents--a831rwxi1a3gzaorw1w2z49dlsor--' --compressed > > It is like an example in https://github.com/ipfs/js-ipfs-api#tooling. > > I want to implement the ipfs add command in my project > http://smalltalkhub.com/#!/~chicoary/SmallIPFS/. > > > > > > ----- > http://chicoary@gmail.com > -- > View this message in context: http://forum.world.st/How-to-generate-Content-Type-application-octet-stream… > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. >
