[SOZO] migrate plan/dry_run does nothing

[itzlambda]

when this is true sozo should perform a dry run of migration but currently its not being used.

dojo/crates/sozo/src/commands/migrate.rs

Lines 15 to 17 in 79278a6

	#[arg(short, long)]
	#[arg(help = "Perform a dry run and outputs the plan to be executed.")]
	pub plan: bool,

---

#Edit

To tackle this issue, the idea is would be to introduce the dry-run flag in the ops related to migration here in sozo.

By having the dry-run passed as argument during the migration, sozo could output the operations, without actually doing them.

Hey @lambda-0x can I take this up?

Hey @faytey for sure, do you have an idea how to start working on this? Don't hesitate if you have questions.

@ameya-deshmukh thank you for your will to contribute. For the sake of order I'll assign to @faytey, hopefully there's a new issue you feel comfortable with.

Except if @faytey prefer to work on something else.

Appreciate your comprehension. 👍

Thank you @glihm i'd take it up, please i'd appreciate a clearer context thanks

Yup for sure. sozo is using dojo-world crate to get the migration strategy that contains everything that should be done:

dojo/bin/sozo/src/ops/migration/mod.rs

Line 132 in 64992c9

let strategy = prepare_migration(target_dir, diff, name, world_address, &ui)?;

This strategy is the one being executed:

dojo/bin/sozo/src/ops/migration/mod.rs

Line 136 in 64992c9

let block_height = execute_strategy(ws, &strategy, account, txn_config)

In the dry mode sozo should output the strategy to be executed, without actually executing it.

So the task here would be you to implement a print function that pretty print the strategy that sozo would execute without the --dry-run option.

Sounds good to you?

@glihm hello glihm, i'm sorry i tried working on this but realized it's written in rust and sought for help from a dojo dev but my issue is that I can't meet up with the odhacks deadline, would you want to assign this to someone else more skilled or can i get extra time to solve it.

Sounds good, no problem and thank you for the feedback. Don't hesitate if in the future you see some issue you want to tackle. 👍
