Meta u kif għandek tiktib mill-ġdid is-storja tal-Git?

Question

Accepted Answer

Git jippermettilek **tiktib mill-ġdid il-istorja** — emendam, rebasing, squashing, jew inqas commits — biex tnaddaf commits jew issolvi problemi. Huwa qawwi imma għandu jsir b'attenzjoni: tiktib mill-ġdid ta'istorja **shared** jikkawża problemi serjosi, għalhekk ir-regoli bih huma kritiki. ## Modi biex tiktib mill-ġdid il-istorja ```text git commit --amend → modify the most recent commit (message or content) git rebase -i → squash, reword, reorder, edit, drop commits (interactive) git rebase → replay commits onto another base (linear history) git reset → move the branch pointer (discard/uncommit) git filter-repo → rewrite MANY commits (remove a file/secret from all history) → All of these change commit HASHES (rewriting = creating new, different commits). ``` ## Ir-regola tad-deheb ```text ⚠️ NEVER rewrite history that has been PUSHED/SHARED (that others may have): → rewriting changes commit hashes → your history DIVERGES from collaborators' → they'll have the old commits; pulls create duplicates/conflicts; chaos ensues → forces everyone to painfully reconcile → a serious disruption ✓ Rewrite ONLY local, unpushed commits (cleanup before sharing). ✗ On shared branches → use REVERT (a new undoing commit) instead, which is safe. ``` ## Użi leġittimi ta' tiktib mill-ġdid (lokal) ```text ✓ Clean up messy WIP commits before opening a PR (squash, reword) → clean history ✓ Fix a mistake in the last commit (amend) before pushing ✓ Keep a feature branch linear/up-to-date with main (rebase) before sharing ✓ Remove a SECRET accidentally committed (filter-repo) — though if it was PUSHED, the secret must be ROTATED (it's already exposed; rewriting alone isn't enough) ``` ## Jekk għandek tiktib mill-ġdid l-istorja shared (raru) ```text → COORDINATE with the whole team (everyone stops, re-syncs) → Force-push carefully: git push --force-with-lease (safer than --force — checks first) → Everyone must reset/re-clone to the rewritten history → Do this only when truly necessary (e.g. purging a leaked secret) and with agreement. ``` ## Għaliex dan huwa importanti Fhim meta u kif tiktib mill-ġdid is-storja tal-Git huwa għarfien importanti ta' livell għoli għax tiktib mill-ġdid l-istorja huwa **qawwi imma perikolus**, u fehim ir-regoli — speċjalment dwar l-istorja shared — jipprevjeni problemi serjosi filwaqt li jippermettilek naddif leġittimu. Il-ħarfien tal-**modi biex tiktib mill-ġdid** (amend għall-aħħar commit, interactive rebase għal squashing/rewording/reordering, rebase għal istorja lineari, reset, filter-repo għal tibdiliet fuq skala kbira) u li kollha huma **jibdlu hash-ji tal-commits** (joħolqu commits ġodda) huwa l-fundazzjoni. \il-aktar kritikal, il-fehim tar-**regola tad-deheb — qatt tiktib mill-ġdid l-istorja shared/pushed** — huwa essenzjali għax tiktib mill-ġdid jibdel hash-ji, jikkawża l-istorja tiegħek tendivergja minn dik tal-collaborators (li għad għandhom il-commits il-qodma), wat-twassil għal duplikati, konflitti, u rikonċiljazzjoni difficli; tiktib mill-ġdid ta'istorja shared huwa disturb serju li din ir-regola tipprevjeniha, b'**revert** (commit undoing ġdid sigur) bħala l-approċċ korrett għal branches shared minflok. Il-fehim tal-**użi leġittimi lokal** (naddif WIP commits qabel PR, emendam ta'mistakes qabel push, rebasing biex tibqa' lineari qabel tqassam — kollha fuq commits lokal, unpushed) jicchjarifi meta tiktib mill-ġdid huwa xieraq u valuwż. Nuwwanza ta' sigurtà kritika: jekk **sigret ġie committed u pushed**, tiktib mill-ġdid l-istorja biex inqassieh huwa insuffiċjenti — is-sigret huwa espost diġà u għandu jkun **rotated** (punt ta' sigurtà importanti tad-dinja reali). Il-ħarfien kif **thendel ir-rewrite raru meħtieġ ta'l-istorja shared** (koordinazzjoni tat-tim, `--force-with-lease` minflok `--force`, kulħadd i-re-sync) jirrifletti ġudizzju maturi. Bħal li tiktib mill-ġdid l-istorja huwa qawwi imma jikkawża problemi serjosi meta jitwassla ħażin fuq l-istorja shared, u bhall-fehim ir-regola tad-deheb, użi leġittimi, u prattiki sikuri huwa essenzjali għall-użu responsabbli tiegħu, il-fehim meta u kif tiktib mill-ġdid is-storja tal-Git huwa għarfien importanti ta' livell għoli — suġġett fejn il-fehim ir-regoli ta' sigurtà (speċjalment qatt tiktib mill-ġdid l-istorja shared) jipprevjeni diżastri ta' kolaborazzjoni reali, jirrifletti l-ġudizzju mistenni għal rwoli għoli li jaħdmu mal-Git fit-timijiet.
