🛠️🛑 Ubuntu dă înapoi: Canonical revine la clasicul cp din GNU coreutils după ce varianta scrisă în Rust a blocat generarea imaginilor Live 🚀🐧

Echipa de ingineri din spatele Ubuntu s-a lovit de o problemă tehnică neșteptată în încercarea sa curajoasă de a moderniza nucleul sistemului de operare cu instrumente de ultimă generație. Canonical a fost nevoită să retragă de urgență utilitarul cp (copy) scris în limbajul Rust și să revină la versiunea clasică din pachetul standard GNU coreutils, după ce noua implementare a blocat complet procesul de compilare a imaginilor ISO oficiale (Live image builds).

Această mutare face parte dintr-o tendință mai largă din lumea Linux de rescriere a utilitarelor de sistem fundamentale în Rust pentru un plus de siguranță a memoriei și performanță, însă incidentul demonstrează că înlocuirea unor instrumente vechi de decenii nu este deloc lipsită de riscuri.

Iată detaliile principale ale acestei decizii:

🔹 Modernizarea care a blocat infrastructura:
În dorința de a testa utilitarele din suita uutils (o rescriere open-source în Rust a faimoaselor GNU coreutils), echipele de dezvoltare Ubuntu au integrat experimental noul utilitar cp. Deși în testele izolate de zi cu zi aplicația părea stabilă, problemele majore au apărut în momentul în care scripturile automatizate ale Canonical au încercat să genereze noile imagini ISO zilnice pentru utilizatori.

🔹 De ce s-au prăbușit build-urile?
Procesul de creare a unei imagini Live de Ubuntu presupune manipularea unor structuri complexe de fișiere, link-uri simbolice (symlinks) și permisiuni speciale, adesea executate în medii izolate de tip chroot/fakeroot.

Varianta în Rust a lui cp a dat erori severe sau s-a comportat diferit față de implementarea clasică GNU în C atunci când a avut de gestionat cazuri particulare de copiere a metadatelor și a atributelor extinse ale fișierelor.

Acest comportament nealiniat 100% cu standardele istorice a dus la eșuarea automată a scripturilor de build, lăsând dezvoltatorii fără imagini ISO funcționale.

🔹 Revenirea la siguranța oferită de GNU:
Pentru a nu bloca activitatea programatorilor și pentru a garanta livrarea la timp a actualizărilor de sistem, Canonical a decis să aplice un revert imediat. Ubuntu a revenit la pachetul tradițional GNU coreutils, care rulează impecabil și neschimbat pe miliarde de dispozitive de peste 30 de ani.

💡 Lecția din spatele incidentului: Deși Rust este lăudat pe bună dreptate pentru securitatea sa, înlocuirea utilitarelor critice din Linux necesită un nivel de compatibilitate perfectă în procente de 100%. Chiar și cea mai mică diferență în modul în care un flag sau o eroare este returnată poate rupe scripturile gigantice de automatizare din spatele marilor distribuții.

Experimentul va continua cu siguranță în ramurile de testare, însă pentru moment, clasicul cod în C își păstrează coroana în producția stabilă Ubuntu.

#Python Hypothesis package now requires #RustLang. This is a scale of reverse dependencies I can't handle. I guess this means it's the end of WD40 profiles on #Gentoo, and therefore the end of support for Alpha, ARM<v6, HPPA, M68k, i486 and some other random subsets of architectures and profiles. Thanks for all the fish, etc.

cargo-semver-checks output where the "function now doc hidden" lint is triggered, warning that the "black_box" function in library/core/src/hint.rs is now #[doc(hidden)] and no longer public API. The run took 6.7s total.

Second, an improvement to how we normalize types.

We'll need this to implement type-checking lints in the future. This will eliminate a large class of expensive type-checks where the previous logic was unnecessarily conservative and quite inefficient.

It's Thursday, day 4. Today's haul so far is ~2500 LoC.

First, making use of default-value stability which we previously exposed in rustdoc JSON. Pairing with Codex on this caught a subtle new edge case that affects which traits are considered sealed.

I had to take a brief detour to triage a surprising new class of SemVer breakage.

It's always *a time* when the net result is "8 issues across 5 repos" 😅

The net result is the same: even more lints!

#rust #rustlang #semver

It's Wednesday, day 3.

Default-stability is in rustdoc JSON in today's nightly Rust. Only *stable* defaults are public API, so we pretend unstable values don't exist.

I'm working on a PR for this, and also on type normalization improvements to let us have type-checking lints 👀

#rust #rustlang #semver

Huh, so Rust doesn't seem to have a net/http/httptrace equivalent. It *should* be fairly straightforward to wire something up using hyper.

I am more and more actively looking to find a new career opportunity. I've been stuck classified as a senior engineer for most of my working life. Every employer promising career progression; never following through.

Would really like to work with embedded systems in #RustLang (no pro exp yet). Though I am open to a wide variety of systems programming.

I have been remote first for almost a decade now. Basically a hipster-wfh. I do well with async practices and keeping people in the loop.

Are there any places hiring for remote people in Australia Eastern Time zone? Even if there are companies in other areas that know the benefit of async work!
