Vladimir Sitnikov commented on OPTIQ-296:
-----------------------------------------
{quote}it seems that the vast majority of changes are renames ('git mv').
{quote}
Git does not rely on {{git mv}} to detect renames. It just compares the content
and understands that the file was moved no matter how do do the rename.
{quote}3. Sounds good. I think we'll lose the git history for those migrated
modules, right?{quote}
Here's how we can keep history:
{noformat}
git clone https://github.com/julianhyde/optiq.git
git subtree add --prefix=linq4j https://github.com/julianhyde/linq4j.git master
git subtree add --prefix=example-csv
https://github.com/julianhyde/optiq-csv.git master
{noformat}
Here's the result:
https://github.com/vlsi/optiq-tmp/blame/retired/linq4j/src/main/java/net/hydromatic/linq4j/AbstractEnumerable.java
This becomes unusual git tree (with multiple roots), however that is exactly
what we want if we need history.
Bonus point: I guess after-the-fact pull requests from linq4j and optiq-csv are
possible as well, however that is not a priority.
I often use commit history/blame in IDE to get familiar with the code. For
instance, it enables you to link test-case with the required changes that made
test work.
