Bug description:
SRU Justification:
[Impact]
Debian source format 1.0 cannot remove files, create symlinks and change
permission in the .diff.gz tarball. Therefore any changes in these 3
categories cannot be represented without any tricks. To solve this,
the `reconstruct` script is used every time we build the source package.
The script is generated by `gen-auto-reconstruct` script during `cranky
close`. It checks if there has been any changes in the 3 categories
mentioned above between the upstream version (i.e v6.5) and the current one.
The problem with the script is that in case a file A was removed since the
upstream version was released, the `reconstruct` script will contains
these commands in this exact order:
rm -f A
chmod -x A
The second command will fail because file A does not exist anymore.
This is solved by generating the `chmod +/-x` commands before `rm`.
Which results in:
chmod -x A
rm -f A
But because the reconstruct script is used during `clean` rule which is
triggered pretty much during every cranky step which is run in the
source repo, the first command will always file because file A is not
present anymore in the tree. To solved this, any `chmod` change is added
only if the file has not been deleted. Therefore if file A has been
deleted, the `reconstruct` script will contain only this:
rm -f A
[Fix]
Generate chmod commands first.
And when generating chmod -x command, first check if the file has been
deleted. If yes, no need for a chmod command.
[Test Plan]
It was tested for cycle sru 2023.10.30 for mantic,lunar,jammy and focal and
it reconstruct script looked correct.
[Other Info]
An example of this is #lp2038611 where `script/is_rust_module.sh` was
removed, but we keep seeing
"chmod: cannot access 'scripts/is_rust_module.sh': No such file or directory"
because `rm -f` and `chmod -x` command were generated.
