paru -Syu will lock up with a mem-leak (?) when looking for devel updates #360

Taijian · 2021-05-06T11:38:26Z

Affected Version

paru v1.6.1 - libalpm v12.0.2

Description

When invoking paru -Syu, execution of paru will stall at the Looking for devel upgrades stage. One CPU core will be utilized at 100% while RAM usage will start to climb indefinitely (until OOM hits).

I am using a local repo for my AUR packages, which is configured in paru.conf and has been working fine until the latest update.

Output

~/.config/paru/paru.conf

See the paru.conf(5) manpage for options

How many git packages do you have? Only thing I can think is you have so many it OMMs as they are all checked in parallel.

Taijian · 2021-05-06T15:06:24Z

I currently have 9 (nine) -git packages installed. I also have 16 gigs of RAM and another 16 gigs of swap, so that would be some rather badly optimized routine that would fill that outside of a bug...

Morganamilo · 2021-05-06T15:08:15Z

Yeah 9 wont be anything close to cause that. Are you experienced with debugging? Could you get a backtrack?

Taijian · 2021-05-06T15:11:07Z

Sure, if you could give me some pointers on what to do, I'll be happy to try to be helpful in debugging (can't guarantee I will, though, cause really not a software developer here...).

Morganamilo · 2021-05-06T15:15:00Z

While paru is running you can attach to it with GDB and print a backtrack with 'bt'. You'll need to run paru using cargo to get debugging symbols.

Morganamilo · 2021-05-06T15:17:02Z

Alternatively if you can limit how much ram paru is aloud to use it should panic from failure to allocate.

Taijian · 2021-05-07T10:36:18Z

OK, because I do not know how to do the things you asked me to do, I instead did something I DO know how to do (don't you just love testers like me?...) - I ran a git bisect.

Anything prior to this one runs fine, anything after this will run 100% on one cpu core until all available memory is filled and then crash the session.

Morganamilo · 2021-05-07T10:38:14Z

Interesting. Does it still lock up with --nodevel?

Morganamilo · 2021-05-07T10:39:33Z

Oh and with --noupgrademenu?

Taijian · 2021-05-07T10:40:47Z

--noupgrademenu works fine, --nodevel crashes.

Morganamilo · 2021-05-07T10:42:01Z

That's funny cause that commit only changed code in upgrade menu.

What's your pacman version? pacman -Q pacman

Taijian · 2021-05-07T10:43:15Z

$ pacman -Q pacman
pacman 5.2.2-3

Morganamilo · 2021-05-07T10:50:17Z

And how about paru -Sua and paru -Su --repo? does one of those not crash?

Taijian · 2021-05-07T10:52:38Z

paru -Su --repo is fine, the other one crashes. Which makes sense, because the crash always only occurs at the AUR stage, not before.

Taijian · 2021-05-07T10:53:09Z

paru -Syu --repo is also fine, btw.

Morganamilo · 2021-05-07T11:02:58Z

My guess would be It's a bug in the AlpmLIstMut code in the alpm bindings. That's going to be a bit of a pain to find.

Morganamilo · 2021-05-07T11:20:14Z

Does it work on the debug branch? I changed the code to not call .retain in cause that is the buggy function.

Taijian · 2021-05-07T11:55:11Z

$ paru -V
paru v1.6.0.r7.gdaf6f74 - libalpm v12.0.2

Sorry, no dice, still crashes... :(

Morganamilo · 2021-05-07T11:57:21Z

I don't think I can do much more unless you manage to get a backtrace of where it's stuck or get an mre.

Taijian · 2021-05-07T11:58:08Z

OK, could you ELI5 for me how to get a backtrace, then?

Morganamilo · 2021-05-07T11:58:53Z

run paru, then in another terminal type gdb -tui --pid $(pgrep paru) and then in gdb type bt.

Morganamilo · 2021-05-07T12:06:20Z

Run paru through cargo. The package in the AUR is stripped of debugging symbols.

Taijian · 2021-05-07T12:07:47Z

Ah, this is where that whole ELI5 comes in again. Because I have no idea how that works. :)

Taijian · 2021-05-07T12:23:05Z

Would it work if I just compile it with !strip?

trevorgunn · 2021-05-07T12:23:38Z

Run cargo run -- <pacman flags> inside the git repository.

Morganamilo · 2021-05-07T12:24:58Z

Would it work if I just compile it with !strip?

That would work.

Though if you don't know how to use cargo did you actually test the debug branch?

Taijian · 2021-05-07T12:26:33Z

source=("git+https://github.com/morganamilo/paru.git#branch=debug") should work inside the PKGBUILD, sholdn't it?

Taijian · 2021-05-07T12:32:15Z

Would it work if I just compile it with !strip?

That would work.

Though if you don't know how to use cargo did you actually test the debug branch?

Actually, it didn't...

The PKGBUILD compiles with --release which will affect the debug symbols; you should just run cargo run -- <pacman flags> manually.

This is from the debug branch.

Now that's useful. Will look when I'm home.

paru/src/upgrade.rs

Line 97 in daf6f74

pad = db_pkg_max - (db.len() + pkg.len()) + 1

because db_pkg_max is a usize (unsigned) it might be as simple as moving the +1 earlier.

@Taijian if you still have some time, would you mind editing that line in upgrade.rs (line 97 in the Debug branch) to read:

pad = db_pkg_max + 1 - (db.len() + pkg.len())

and see if that fixes anything?

Taijian · 2021-05-07T12:55:33Z

Nope, did not help...
