Re: Segfault with ZnClient and https

by Petter

Hi Sven and thanks for answering! I did try a ldd and all libraries are present. I also started pharo with gdb and it seems problem is somewhere in the combination between libgit2.so, libssl.so and libcrypto.so.1.0.0, most often the crash comes from libssl.so. Exchanging libgit2.so with the os-version make ZnClient work, but then Iceberg on the other hand stops working. I pretty much gave up Fedora and reverted to safe Ubuntu. Maybe I can dig deeper into this later, but we are pretty close to a production setting now :) Petter -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: Seaside disappearing under Windows

by kmo

Hi - Firstly, have you tried asking on the Seaside forum? Might be worth doing. If it were me, I would try to see if it was a problem with my specific application or a a general seaside/windows problem. Does the Seaside demo app work? Can you write a simple Hello World seaside app. Does that work? I would just try to constantly narrow down the problem. Not much help, I know. But these were the thoughts that occurred to me. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Segfault with ZnClient and https

by Petter

Hi, I have trouble with latest Fedora 33, plain installation and Pharo 8.0 stable, 64 bit. When I try a ZnClient new url: 'https://something..'; get. The image segfaults. Last lines from log are: primitiveSSL:setStringProperty:toValue: atAllPut: atAllPut: primitiveSSL:connect:startingAt:count:into: stack page bytes 8192 available headroom 5576 minimum unused headroom 5952 --- It seems libssl and libcrypto is bundled togheter with Pharo, looks like version 1.0.0. I then try to compile openssl with 1.0.0-stable which I build myself, but when replacing the Pharo-libs with my own I get the message that I am using a too old tls-version error. I am a little confused on what is happening here. Do anyone have a clue?

Re: Postgres P3 Driver in seaside/web apps - strategy for "prepare:"

by Esteban Maringolo

Not completely related, but also not unrelated. (?) You can pool your connections in the server side by means of pg_bouncer [1] to scale tenfold (or more) the connectivity to your PostgreSQL server. So you can program with P3Client and then when you need to scale the connectivity, simply do it on the server side. Of course if you have 1000s of P3Clients on a single image, then it might take a big toll on the memory use, so it also depends on how you balance connections.

First make sure that you give each session in your (seaside) web application its own connection/client to the database. P3Client is meant to be used single threaded, it is your responsibility to protect this. Make sure these are initialised and disposed of properly - use logging.

Postgres P3 Driver in seaside/web apps - strategy for "prepare:"

Hi using the P3 Postgres driver what is the optimised way of using the following in a seaside/web application statement := client prepare: ... statement execute: statement close. Sven readme on the drivers page "prepared statements ... need to be closed, prepared statement exist ... single session / connection ..." Typically in a desktop app I would fire the "prepare" statements(s) once when open the particular UI / window (say typically 2 or 3 statements in a UI) and then "close" when I exit How does this work in a multi-tabbed browser app lets say I open a tab with a particular UI and fire the "prepare" statement now what if the tab idles for too long - and then i press send/save. The program would have just fired the "execute ..." assuming the prepare is active. would the prepare / session have been automatically closed ? - when should i typically fire the prepare statement - how should i test if the session / prepare is still active or needs to be refired - how are orphan prepare statements disposed off ny the database / program thanks for pointers Sanjay ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Thanks for the details. I think that with the one from Norbert, you and me[1], there are at least 3 static site generators made with Pharo (and there was an old one, but I don't remember its name and I think is unmaintained). I wonder if there is some kind of Awesome Pharo alike list, to start adding them to a known place. There is the Pharo Documentation Wiki[2], but I kind of remember a longer more detailed list. Ummm... now I wonder if we could list a kind of decentralized list of "Powered by Pharo" projects taken from our personal, community or enterprise web sites. We may agree on using some kind of tags in the metadata to recover such distributed catalogue of projects. Certainly in my (incomplete) recent portfolio[3], Pharo has been a constant, in visible and invisible ways.

I completely forgot I could do that, thanks for reminding Pierce (its almost better as well, as you can build your image, save it, then run tests on it, and then if it passes all your stages you can included the saved version in your docker build... which sits better with me as it also means that log artifacts etc can be more easily examined for failures (and your not trying to console into a docker image to figure it out). As a nice side effect - if you are doing this in something like Gitlab - you have your project source already there and so you can avoid an extra checkout step, so its a little bit faster. > > > > Pierce - who/where are you rnning your Docker image?
