About tagging... It looks super ackward to me to tag EVERY commit with "build information".

I'm not sure which comment your responding to, and not sure what you mean by "build information", but obviously someone may do several commits before doing a pull request, as they work through developing and testing a fix for an Issue.�� Its only the successful builds that are uploaded to files.pharo.org that are important to tag.
��
Building does not mean releasing... I prefer the other way around: we tag builds with commit information. Like that we know how to reproduce the build.

I'm ok with tagging build artifacts by explicitly saying "this is BUILD #X", which is ~= from "this is RELEASE #X".

I'd imagine that tagging a commit as BUILD#X would be done as part of the CI immediately before the upload to files.pharo.org.

Moreover, before we needed to store ALL versions of the image because that was the way we versionned the system. Now, every commit in the #development branch should be buildable (delta some bugs of course ;)). This means that we can rebuild all images by just iterating the git history and building from scratch.

I don't understand why you'd need to iterate git history. ��
Shouldn't you be able to rebuild an image from a single git commit?
��
No need to store all images.

Do you mean on files.pharo.com?��
That might be a good later goal, but for now these resultant images are useful to work with PharoLauncher without expending effort on redeveloping that to also rebuild images on the fly.

I made a PR

https://github.com/pharo-project/pharo/pull/185

this PR adds a script that will rename built archives accordingly. I propose the following file names for the zip:

Pharo${IMAGE_KIND}-7.0.0-arch.32bit.sha.${HASH}.build.${BUILD_NUMBER}.zip

+1 to Torsten's suggestion to put the BUILD_NUMBER first, since it is more sortable than HASH.
By "arch", do you mean Win/Linux/Mac? Or were labelling the bit-ness field?
Also, is it important to prepend these with the numbers with "build." and "sha." fieldname strings? This bulks out the name increases the chance some interface needs to mangle the name to fit into a thin column.��

While we are discussion version naming (and I ask this from a position of ignorance)
could you discuss with your team, without insider knowledge, how do we distinguish between the released 7.0.0 and all the 7.0.0 development builds heading towards that release?
Can we add something to distinguish the development phase
i.e. alpha/beta/rc/release (which coincidentally sort well with build numbers.)

�� Pharo-${IMAGE_KIND}${BITNESS}-7.0.0-alpha.${BUILD_NUMBER}.${HASH}.zip
�� Pharo-${IMAGE_KIND}${BITNESS}-7.0.0-beta.${BUILD_NUMBER}.${HASH}.zip
�� Pharo-${IMAGE_KIND}${BITNESS}-7.0.0-rc.${BUILD_NUMBER}.${HASH}.zip
�� Pharo-${IMAGE_KIND}${BITNESS}-7.0.0-release.${BUILD_NUMBER}.${HASH}.zip

beta might be the defined point to ask applications to test-port to the new version, this perhaps being the optimum point to get fixes into the the next release.

or if you don't want to be that sophisticated, maybe just phases dev/rel��

or for a more continuous release process, maybe '#' for the patch number...
�� Pharo-${IMAGE_KIND}${BITNESS}-7.0.#-${BUILD_NUMBER}.${HASH}.zip
(since '#' sorts before '0')

Where:

IMAGE_KIND is the built product (core image, image with monticello, image with metacello, full image...)
HASH is the commit hash
BUILD_NUMBER is the build number set by jenkins, or "nobuildnumber" if not available


Moreover, this only makes part of a "prepare for upload" script and not the main build process. That is because of simplicity right now. However, if we put the build number by default in the main archives, there may be several drawbacks:

��- PR's builds will have build numbers conflicting with the main builds (which may be confusing)
��- when building locally, we do not necessarily have a build number available so it does not make much sense

Once the PR is accepted/integrated, we should change the build process to use this script.

Hi, I created an issue:


I propose to keep both the sha and add the build number. Also, to follow semantic version conventions, we should use $- instead of $/. Something like:

{Major}.{Minor}.{Patch}-sha.{sha}.build.{buildnumber}

What do you think? I'll propose a pull request in some minutes.

Hi torsten

Yes it sounds good to have MAJOR.MINOR.PATCH/BUILDNUMBER scheme
