[question] Revision mismatch between OSes

[brosmar]

What is your question?

I am using conan 1.60.1 with revisions enabled.
I am supporting multiple platforms.
I am storing artifacts in the JFrog artifactory.

Artifacts are stored here:
https://myartifactory.com/ui/repos/tree/General/xentric-conan-dev-local/master/SYCA_Casting/0.4.7/dev/250c0c08c53af2d9364c14c084f35280/package/485579f82c8813e2e25fbe180219a4ccf73be7b9/09b65d5aa6ae24acb652feefd8de99d5/conan_package.tgz

Is the following naming correct?

A Recipe-HASH: 250c0c08c53af2d9364c14c084f35280
B Package Revision-HASH: 485579f82c8813e2e25fbe180219a4ccf73be7b9
C Binary Revision-HASH: 09b65d5aa6ae24acb652feefd8de99d5

When I am building the module SYCA_Casting on different platforms the A hash is changing when I am compiling the same sources on different platforms. I am asking this because when I am building an package on paltform1 which is using SYCA_Casting/0.4.7@master/dev the revision is always downloaded from the newest A-HASH. When the compile for the module was done on a different platform2 and uploaded just before the compile of module fails because SYCA_Casting/0.4.7@master/dev for platfom1 not found in the repository because the version has an old A-Hash.

Have you read the CONTRIBUTING guide?

Hi @brosmar

Thanks for your question.

A Recipe-HASH: 250c0c08c53af2d9364c14c084f35280
B Package Revision-HASH: 485579f82c8813e2e25fbe180219a4ccf73be7b9
C Binary Revision-HASH: 09b65d5aa6ae24acb652feefd8de99d5

The B is called package_id not revision, and it is more or less the hash of the configuration (profile + dependencies)
The recipe-revision (A) and package-revision (C) are the hashes of the contents, the actual files hashes of the package recipe and package binary respectively.

When I am building the module SYCA_Casting on different platforms the A hash is changing when I am compiling the same sources on different platforms. I am asking this because when I am building an package on paltform1 which is using SYCA_Casting/0.4.7@master/dev the revision is always downloaded from the newest A-HASH. When the compile for the module was done on a different platform2 and uploaded just before the compile of module fails because SYCA_Casting/0.4.7@master/dev for platfom1 not found in the repository because the version has an old A-Hash.

The most common cause for this would be a discrepancy in the sources. And one of the most common causes is the different line endings (LF vs CRLF in windows). This would be summarized in https://docs.conan.io/2/knowledge/faq.html#error-obtaining-different-revisions-in-linux-and-windows, the recommendation is to use the same line-endings everywhere (LF), it is easier, more consistent and all editors even in Windows including Notepad, support LF.

Please let me know if this helps.
