[tycho-dev] Bundle.info doesnot get updated when all tar.gz of the particular runtime(profile) deleted

[Kasun Siyambalapitiya]

Hi all,

When we install new features or uninstall existing features on a particular
runtime(profile) using p2 provisioning, lot of `tar.gz` files are being
created to keep track of the features being installed/uninstalled in the
selected runtime. Since the content of those files are added in incremental
order, I deleted all the `tar.gz` files without the latest `tar.gz` and
tried installing new features and uninstalling existing features, they
worked fine and update the bundle.info correctly.

To research even a bit further, I deleted all the `tar.gz` files of a
particular runtime and tried the following


- Installing a new feature which has a dependency to a feature which is
already exists in the current runtime

it failed, indicating the dependant feature is not present.
this is obvious as no history is present


- Uninstalling an existing feature

Also failed indicating the relevant feature is not
found, this is also obvious as no history is present


- Installing a new feature which has no dependency to any feature which
is already exists in the current runtime.

The build passed without any issue but bundle.info of the relevant runtime
did not updated as it should be.

Could anyone be kind enough to explain the reason behind not updating `
bundle.info` in the third scenario?


Thanks in advance.
