Re: [Pharo-project] [Progress Report] Zinc HTTP Components

by Sven Van Caekenberghe

Philippe, First of all, thanks a lot for taking the time doing these benchmarks. I know you are very well placed to do these test, so I am honored you did. Second, although this is a static page bypassing encoding, the results are very impressive indeed. It is still Seaside and a 16KB page. Furthermore, all request completed successfully with a good distribution. This makes me quite happy! I do however suspect some serious hardware being used. Could you elaborate on the hardware, OS, VM and other details ?

[Pharo-project] a slim holiday present, cpic

by Eliot Miranda

Hi All, don't know if this is useful to you or whether you've already written it yourself but I finally caved and wrote a shell command that copies an image/changes file pair, replacing the hundreds of times I've issued the two parallel commands, cpic = copy image and changes. Happy holidays -------8<------- #!/bin/sh # copy image and changes force=0 if [ "$1" = -f ]; then force=1 shift fi if [ $# != 2 -o "$1" = "-?" -o "$1" = --help ]; then echo "usage: $0 [-f] image-name-no-ext [image-name-no-ext|dir]" test $# != 2 && exit 1 exit 0 fi if [ -f "$2.image" -o -f "$2.changes" ]; then if [ "$force" = 0 ]; then echo "$2.image and/or $2.changes already exist." 1>&2 exit 1 fi elif [ -d "$2" ]; then if [ -f "$2/$1.image" -o -f "$2/$1.changes" ]; then if [ "$force" = 0 ]; then echo "$2/$1.image and/or $2/$1.changes already exist." 1>&2 exit 1 fi fi cp "$1.image" "$1.changes" "$d" exit 0 fi cp "$1.image" "$2.image" cp "$1.changes" "$2.changes"

Some things may require using changesets or other kind of non-packageable messy code. We will see. Things are scary from distance :) In any case i don't think that a config, which fully describing a conglomerate used to generate VM sources and plugins is any bit worse than image which contains same info. Except that you can't diff two smalltalk images to see what difference between them. -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] Automated VM build server

Sig, Packages would be nice, but I think a more important goal is to get the vm to describe error conditions. If it did that reliably, I would have been completely content to unzip a binary and write a shell script, or just use a one-click image. Of the things that are under reported, the most notable is when a shared library does not load, where did the vm look for it? One gives it a name via #moduleName, but the vm modifies it and then tries to load using the result. If it fails, it needs to say where it looked. What was the error code?

Also, we could test & see if VMMaker loads well and can generate code using different base images. So, we will instantly know if any changes in compiler, or other layers of system is breaking VMMaker. Because having a years old image where VMMaker works 100%, but at same time have 100% chances that it couldn't be loaded (or even if loaded, but can't run correctly) in latest image is not what i think good practice for keeping your house clean. So, by getting rid any intermediate artifacts from build chain we will be able to make sure that: - VMMaker loads w/o problems in latest/multiple image(s) - VMMaker works well and can generate code That's means that for any newcomer, loading and building VM will be much less tedious process, and for 99% of cases it can be fully automated error free process. And let me remind our motto: we're not trying to produce perfect system/setup from first lucky shot. We slowly but steady crawling towards improved state of art.

i know i have done this before, and it's totally escaping me.. i am also not sure if this is the place to ask generic smalltalk questions, so if it's not, please someone let me know.. doing something like: url := 'http://domain/?var1=one&var2=two" url asUrl retrieveContents contents. BUT! i would like to send the vars as POST vars. can i do that with retrieveContents? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

It works well in Squeak. There's a menu item to enable/disable Shout in the workspace, besides the global preference (not Preference) which applies to all workspaces. It also has the features of ShoutMonticello. It could be developed as a shared package between Pharo and Squeak, like VMMaker or OCompletion. What do you think? Levente
