    There was a guy I worked with that tended to want to unilaterally make sweeping changes.

    Like, “we need the user to be able to enter their location” -> “cool. Done. I also switched the dependency manager from pip to poetry”.

    Only a little bit of exaggeration

      Some people, like me, are not built to be developers. I can sculpt code in any language I need for whatever problem I need to solve, but maintaining code over a long period of time, with others, is not my thing.

      The drive to do additional changes is just too high and the tendency for typos or obvious logic errors is too common. (There is one little improvement. It’s right there. One line up. Just change it now while you are in there…)

      I am not stupid and regard myself as a decent engineer but my brain is just wired in a more chaotic way. For some things that is ok. For developing code on a team, not so much.

      Security is the field I am most comfortable with because it allows for creative chaos. Rule breaking is encouraged. “Scripting” is much more applicable and temporary.

        When using git and are working on a feature, and suddenly want to work on something else, you can use git stash so git remembers your changes and is able to restore them when you are done. There is also git add -p this allows you to stage only certain lines of a file, this allows you to keep commits to a single feature if you already did another change that you didn’t commit (this is kind of error prone, since you have to make sure that the commit includes exactly the things that you want it to include, so this solution should be avoided). But the easiest way is when you get the feeling that you have completed a certain task towards your goal and that you can move on to another task, to commit. But if you fail you can also change the history in git, so if you haven’t pushed yet, you can move the commits around or, if you really need to, edit past commits and break them into multiple.

      • I tell my young developers - the primary goal in software engineering is maintainability. Code reuse, encapsulation, abstraction, and myriad other concepts all contribute to ease of maintaining source code over the long term. Maintainability allows for easier, predictable feature addition and removal, with fewer changes, and by different people. You’re also a different person than the one you were months or years ago when it comes to software.

        • Did I already post in here about how he wrote a custom DSL instead of using the standard widely used ORM we use everywhere? Maintainability nightmare.

          He doesn’t work here anymore and now I have to either figure it out or rip it out. So far it looks like “rip it out” because it took less than an hour to swap in the orm, and now there’s just a lot less code needed.

        Very relatable. Especially when it’s less effort to make the change than it is to try and ignore it. But it’s understandably harder for those who are reviewing your work.

  • Last time somebody did this to me there were a lot of sit downs about how to properly chop up large scale code changes and why we don’t sit on our own branch for two months.

    “How long will this take to get in?”

    “Well, two weeks for me to initially review it, a week for you to address all the changes, then another week or so for me to re-review it… Then of course we have to merge in all the changes that have been happening in primary…”

    Please, no, I get flashbacks from my 6-month journey (still ongoing…) of the code review process I caused/did. Keeping PR scope contained and small is hard.

    From this experience, I wish GitLab had a “Draft of Draft” to tell the reviewer what the quality of the pushed code is at: “NAK”, “It maybe compiles”, “The logic is broken” and “Missing 50% of the code”, “This should be split into N PRs”. This would allow openly co-develop, discuss, and steer the design, before moving to nitpicking on the naming, formatting, and/or documentation details of the code, which is likely to drastically change. Drafts do work for this, but the discussions can get uncomfortably long and convolute the actual finishing of the review process.

    Once both reviewer(s) and the author agree on the code design, the “DraftDraft” could be collapsed into a link in an normal Draft to be mocked next. The scope of such draft would be limited by the earlier “DraftDraft”.

  • This does seem like a potential issue if the PR is itself implementing more than one vertical slice of a feature. Then it could have been smaller and there might be wasted effort.

    If the patches are small and well-organized then this isn’t necessarily a bad thing. It will take more than one day to review it, but it clearly took much more time to write it.

    I try to keep my changes under 300-350 lines. Seems like a good threshold.

    I’m still annoyed that Github doesn’t have good support for stacked diffs. It’s still not possible to say that one PR depends on a different one, and still has no ability to review and land them as a stack.

        Making PRs against a feature branch still has the same problem.

        Say you’re working on a major new feature, like adding a new log in flow. It’s a good idea to split it into many small changes: create initial log in form, implement user sessions, add SSO support, add “remember me” functionality, etc.

        Those changes will likely depend on each other, for example adding the “remember me” checkbox requires the form to actually be built, and you probably don’t want to wait for the reviewers to review one change before continuing your work. This means you naturally end up with PRs that depend on each other in a chain.

        Stacked PRs (or stacked diffs, stacked MRs, whatever your company calls it) means that:

        1. The code review tool lets you specify dependencies between the PRs, for example the “remember me” PR depends on the initial login form implementation
        2. It shows the dependencies visually in the UI, like a chain or tree
        3. Changes can’t be landed until the PRs they depend on have been reviewed
        4. There’s a way to land an entire stack
        5. When you review a PR later in the stack, it doesn’t show any of the changes that were made earlier in the stack. Each PR focuses just on the changes in that part.
        6. For each PR, the build steps and linters run for all the changes in the stack up until that point. It helps detect if incompatible changes are made earlier in the stack.

        Making all your commits directly to a branch then creating a PR for the whole branch is similar, but reviews are a nightmare since it’s only a single review for the entire branch, which can be thousands of lines of code.

        At my workplace, we use feature flags (essentially if statements that can be toggled on or off) rather than feature branches. Everyone works directly from the main branch. We use continuous deployment which means landed code is quickly pushed to production. New features are hidden behind a feature flag until they’re ready to roll out.

            You can make a PR against your feature branch and have that reviewed

            But what if you have multiple PRs that depend on each other? Or are you saying only have one PR open at a time? That sounds like it’d be very slow?

            • I suppose it is possible to have two PR that have changes that depend on each other. In general this just requires refactoring… typically making a third PR removing the circular dependency.

              It sounds like your policy is to keep PR around a long time, maybe? Generally we try to have ours merged within a few days, before bitrot sets in.

                Sorry, my comment was unclear. I didn’t mean a circular dependency, just PRs that have a chain of dependencies (e.g. PR 100 that depends on 99, that depends on 98, that depends on 97)

                They’re usually not around for a long time, but there can be relatively large chains if someone is quickly adding new features.
