Git

A bloated .git directory spanning several gigabytes is rarely an accident. It is the sum of every commit, every rebase, and every accidentally committed binary that Git never deletes on its own. This article explains how loose objects turn into delta-compressed packfiles, what git gc actually does under the hood, what role the reflog plays in preventing data loss, and how to diagnose and shrink a bloated repository.

Anyone who only uses git log with its default output is giving up one of the most powerful diagnostic tools in daily development work. With targeted filters by author, date and content, with custom pretty formats for scripts, and with pickaxe search, any line of code can be traced back to its origin without manually scanning the history.

A properly configured .gitattributes file solves problems many PHP teams consider unavoidable: CRLF noise between Windows and Linux, bloated deployment archives, skewed GitHub language stats caused by vendored code, and unreadable pull request diffs for generated or minified files. This article walks through every relevant directive with real examples for PHP and Magento projects, covering line endings, export-ignore, linguist attributes, and diff drivers for everyday development.

Committing PSD files, videos, or archives straight into Git needlessly bloats repository size and clone time for the whole team, because Git's delta compression barely works on binary data. Git LFS replaces these files with lightweight pointers and stores the actual content externally, without changing the familiar commit and push workflow at all.

Using Git without a thoughtful configuration means committing with the wrong identity, fighting a messy history, and losing time when switching between projects. The three config scopes system, global, and local follow a clear precedence, letting you set up editor, rebase behavior, aliases, and per-project overrides via includeIf in a clean, predictable way.

When a bug has crept in somewhere among hundreds of commits, manually clicking through history burns valuable time. git bisect finds the guilty commit through binary search in just a handful of steps, whether tested manually or fully automated with a test script, turning hours of hunting into a matter of minutes.

Anyone who suddenly needs to switch branches mid task knows the dilemma between half finished code and a clean working tree. git stash safely sets aside uncommitted changes, manages several named stashes at once, allows partial saving of individual hunks, and clearly distinguishes between pop and apply so interrupted work never gets lost.

A password accidentally committed to Git or a multi gigabyte node_modules folder baked into history cannot be fixed with a new commit, because every old version stays in the repository forever. This article explains when rewriting history is actually necessary, how BFG Repo-Cleaner strips secrets and large files quickly, and what coordination a force-push demands from your team.

"Staging area" is just a nickname. Behind it sits a real binary file with a documented format, its own checksum, and a stage number per entry. This article goes straight into the internals: the file format, what git add actually writes, how git status and git diff use the index as their pivot, how to inspect and manipulate it directly with git ls-files and git update-index, and why git add -p only works because the index is decoupled from the working tree.

Long lived feature branches quietly grow into tangled merge conflicts and cost development teams valuable time on every release. This article shows in practical terms how to keep feature branches short and focused, sync regularly with main, detect oversized branches early and split them cleanly, and use a clear branch per ticket workflow to permanently avoid merge hell in Magento and PHP projects.
