Hi,

I had a look at the Pharo 7.0 today and see metadata for methods (Author and timestamp) has been removed*, what is the reason for this?

Having the ability to find methods created around the same time and/or by author is quite useful when fixing bugs in the core libraries.

There is also quite a lot of history that is lost as well with this change (I am always impressed when I stumble upon methods over 15-20 years old!).

Could this be reverted, please?

[*] all methods have a stamp, but it is the same for all with only a timestamp from the bootstrap(?).

Hi Henrik,

I'm sorry about that, it's probably a side effect of the bootstrap. We may have to track down the cause, so if you can help, it's most welcome :). For that I can explain you the process as it is today:

��1st) We previously exported all code from Pharo to FileTree (Metadataless I think). This step is not done anymore.

��2nd) We bootstrap from the packages on FileTree by first compiling methods without metadata.

��3rd) We export all bootstrap packages from filetree to MCZ

https://github.com/pharo-project/pharo/blob/development/bootstrap/src/Pharo30Bootstrap.package/PBBootstrap.class/instance/exportAllPackagesIntoMcz.st

��4th) Once the first image is ready (without source code nor meta-data) we install monticello and we reload all mcz files

�� This regenerates the source code and should load all metadata in mczs

https://github.com/pharo-project/pharo/blob/development/bootstrap/scripts/02-monticello-bootstrap/02-bootstrapMonticello.st

So either it is that the metadata is lost in Filetree because it is metadataless, or it is lost in the intermediate conversion to mcz, or in the loading.
