When I say "automatically", what I mean is: Yes I know I can `git rebase -i ...` and then in the rebase todo file, manually insert commands to `exec git branch -f orange-phase1` etc... at the right places. But that's a lot of manual thinking and typing just to maintain it. I feel it should be automatic.
Can anyone help me with this?

A #git workflow question.
I have a branch (lets call it "orange"), that adds a whole bunch of features on top of main. I regularly rebase this from main. I also have a bunch of points on that branch marked as other branches ("orange-phase1", "orange-phase2", etc...) that are convenient points for PRs - either currently open or intended in the future.
Is there a way I can **automatically** maintain these branches whenever I `git rebase main`?

I was watching father-in-law attempting to view a 20ish minute YouTube video to teach something. It wasn't even that much to learn but every 2 minutes or so the video was interrupted by the same 15second advert. I wasn't even interested in watching it myself but even I was getting annoyed at the advert.
I didn't think a lesson in Firefox plus uBlock would have gone down well at the time though.

Indeed so, in fact it was quite a bug waiting to happen. Before that change, I was about to make a bugfix and then realised I would have to edit both sides of the ifdef, and then arrange to test both sides as well. It seemed not worth the trouble just for those two old versions (5.18, 5.20).

Today I have decided to bump the minimum #Perl version requirement of Object::Pad up from 5.18 (released in summer of 2013), to 5.22 (released in summer of 2015).

During my recent debugging of a `Future`-related memory leak issue, I had occasion to swap a program from using `Future::XS`, to the pure-perl `Future::PP` implementation instead.
As the program runs a very flat stable CPU load, such a change made it easy to see the performance different such a change made.

Knowing the shape of the code around handling of `Future::Exception` instances, it didn't take me too long to poke around and find a place where a reference is accidentally retained.
After a nested call to the `Future::Exception->new`, the result if `SvREFCNT_inc()`ed to retain it over the `FREETMPS; LEAVE;` at the end of the method call, but we forgot to re-mortalize it when pushing it to the stack for the next call.
An additional `sv_2mortal()` is needed.

For an extra bit of confirmation that this seems to be the bug we're looking for, we can also inspect the `.pmat` files that the failing test wrote.
By running both through the `pmat-diff` tool, it compares the gained and lost SVs on each side, and tries to associate them together. It'll draw a summary of what it finds:
Here we indeed find an ARRAY blessed as `Future::Exception`, holding five other SVs. Seems to match what we'd expect.

Knowing the source of the leak is in `Future::XS` helps narrow it down. That's not a big distribution, not many lines of code that deal with `Future::Exception` objects anyway.
It didn't take me long to manage to write a test using `Test::MemoryGrowth` that indicates failure:

I left this running without `Future::XS` over the weekend to see what would happen.
It did use a constant amount more memory than with (that's to be expected), but it didn't grow at all over the time. Moreover, the per-class breakdown doesn't show any growing collection of `Future::Exception` objects at all. It seems we are on the right path.

Quite so. As I said, I suspect a missing `SvREFCNT_dec()` call somewhere in one of my XS modules. The trick now is identifying which module and where it should go.
Missing code is always the hardest kind to find. ;)

2026-01-09 14:25:26 UTC

- reply

Well the failure itself comes from this line here:
https://metacpan.org/dist/Device-Serial-SLuRM/source/lib/Device/Serial/SLuRM.pm#L707
but knowing this isn't directly any help. The problem is that something somewhere is retaining these exception objects indefinitely and not throwing them away. That's the part I need to investigate.

2026-01-09 14:21:33 UTC

- reply

It also turns out that I forgot to actually document the way to skip loading the `Future::XS` module, so I can't link to any docs of that for this thread ;)
While I leave this to run overnight again and maybe or maybe-not accumulate any more leaks, I can spend a moment to write about that ;)
I think that's enough for today, I'll wait and see what this yields tomorrow...

2026-01-09 14:19:47 UTC

- reply

At this point there are no more immediate steps we can take, so we will have to try a few other ideas.
Knowing the surrounding code, I know there's a couple of XS-implemented modules around Future handling, so it seems likely one of those has forgotten to `SvREFCNT_dec()` an exception reference.
One of those modules, `Future::XS`, is an optional performance improvement and can be skipped. By restarting the program without it we can wait and see if the problem continues.

2026-01-09 14:11:58 UTC

- reply

Next we can try using the `identify` command on this example object, to see what is retaining it, and hopefully gain some insight into the actual bug.
Unfortunately for us, this doesn't lead anywhere. The ARRAY is being held by a scalar REF instance, but nothing in the heapdump can find what is holding on to that.

Picking one of these at random, we can inspect it to see its contents.
The message says it's about a timeout that happened, which again seems to correlate with the occasional staircase shape. These timeouts were rare, so it seems these exception values have been retained by something somewhere.

Next, loading the second file into the `pmat` tool shell lets us poke at it in more detail. Since we already have a good ldea it's related to these `Future::Exception` instances, lets start by grabbing a list of those.
Seems like there's quite a few.
