Re: [Pharo-users] PostgresV2 Driver available?
Hello, actually, I do, although not with Garage or Glorp. I am not sure how exactly is related version in https://github.com/pharo-rdbms/garage and the one on deprecated.smalltalkhub.com/#!/~PharoExtras/PostgresV2 , but I migrated the smalltalkhub one to https://github.com/JanBliznicenko/PostgresV2 and updated dependencies for my own purposes. It might be, however, actually even older than the one in garage repository. Best regards, Jan Esteban A.

Re: [Pharo-users] Question ZnClient with file
Hi,
CC'ing the Pharo Users ML since that gives a permanent record of my answer.
File uploads using ZnClient do work in the common case. You can check
ZnServerTest>>#testFormTest3 or ZnImageExampleDelegateTest>>#testUpload as well
as several other senders of #addPart:
First you are mixing 2 types of forms (see
https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/Zinc-HTTP-Client/Zinc-HTTP-Client.html
section 6. Submitting HTML Forms).
For a file upload you need a ZnMultiPartFormDataEntity which is configured
automatically in ZnClient by #multiPartFormDataEntity when you do #addPart: (no
need to set a content type).
Next you are mixing the file name and the file contents. It is best to use the
class side ZnMimePart instance creation methods, either
#fieldName:fileName:entity: or #fieldName:fileNamed:
Also, when you create a ZnByteArray entity with the contents of a .jpg or .png
you not only have to load the actual bytes (obviously), but you also have to
set the mime type correctly. In #fieldName:fileNamed: you can see how this is
done by using the file extension, but that is just one way to do it, if you
know the type upfront, just set it.
There is also ZnClient>>#uploadEntityFrom: (used by #testUploadSmallDocument)
but that is not using a form.
I am sure you will be able to figure it out, if not just ask.

Great. In production you should also check whether the upload succeeded. One way to do this is by using #enforceHttpSuccess - this will signal an exception unless the host returned a 200 or similar code (assuming the receiving host acts like this). > ... > > Please allow me to ask one more question: > > My situation in my application is, that I do not have the file local as in > the example but in amazon S3 and I have a url like this: > > https://s3.eu-central-1.amazonaws.com/spf-belege-dev/K1000137/201905061113-506963984-9575877/31/7/small-202008241549-7987688-1.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJUHEWICJ33EJAUMA%2F20200830%2Feu-central-1%2Fs3%2Faws4_request&X-Amz-Date=20200830T155656Z&X-Amz-Expires=6000&X-Amz-SignedHeaders=host&X-Amz-Signature=ab3f329b1e63c896f8hh95e36951f199fae081ca > > My question is: Is it possible to NOT download this file to my server for > then sending it with filename and path to the other system but setting this > url directly in the ZnClient? > For the other system it has to be like a file upload... > This would save transfer costs and time. I understand, but unless the host supports this, there is not much you can do. The data has to be transferred, if they are not willing to fetch it from some URL, you will have to do the copying. If the files are not too large, you can take them temporarily in memory if you want (so that you do not have to create a temp file). See ZnImageExampleDelegateTest and how #testUpload uses #image there. It probably would also work with a ZnStreamingEntity (so that not everything has to be in memory at the same time, just the buffer to do stream copying), but that might require some more experimenting. > Regards > Sabine > > > Sabine > > Am So., 30.

Re: [Pharo-users] PostgresV2 Driver available?
Hi, My question was done in a quest to crack an issue with Postgres which was already solved, and it involved the connection, but it wasn't the driver nor the server, but a firewall in between. So I don't see the need, nor I think it would be advisable, to use the v2 driver when the P3 is available and well tested and proven in production. Regards! Esteban A.
