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

Re: Seaside disappearing under Windows

by David Pennington

I have looked at the code. There is only one method for reading and one for writing and they both close the file when they have done so thatâs wouldnât ât seem to be the problem. It still doesnât answer why it works on my M1 MacBookAir and not on two Windows boxes :-( > On 20 Apr 2021, at 16:13, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > > David, > >> On 20 Apr 2021, at 17:01, David Pennington <david(a)totallyobjects.com> wrote: >> >> I have finally given up on trying to sort this out.

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? (git checkouts over ssh works fine, strange enough) Petter -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Assuming you store each object in its own file, you are then also doing a lot of IO. Are you sure that you are properly closing your file streams, in all circumstances ? It is possibly that you run out of IO resources. Also, garbage collection on a server image (without a UI) is sometimes a bit strange, it can take a while to kick in. I am just guessing here. It is still not good that the image/vm quits without any notice, that is for sure. Sven

I have finally given up on trying to sort this out. Under both Windows Server 2012 and Windows 10 my Pharo image just exits leaving nothing, not even a crash file. Hence, I have fixed my MacBookAir so that it stays alive with the lid down and I am now using that as my Seaside server. It has been up for the last 4 days so it seems that this is a Windows only problem and (hopefully) not my code. In passing, I am a high-level programmer in Pharo in that I do not use any special calls or processes. Davids Totally `Objects
