| + | |||
| + | List details about dangling commits ([[https://lukescott.co/2019/05/10/git-finding-lost-dangling-commits/|Git – Finding Lost/Dangling Commits]]: | ||
| + | <code bash> | ||

| + | |||
| + | ====== Reduce repo size ====== | ||
| + | |||
| + | |||
| + | It is important to check if git configured with default settings. | ||
| + | Especially forcing of creation of multiple smaller packs significantly increases repository size. | ||
| + | I.e. changing one 1.2G pack into multiple 256MB packs let, increases size of packs to 4.3GB :( | ||
| + | <code bash> | ||
| + | git config --global -l | ||
| + | git config --system -l | ||
| + | </code> | ||
| + | |||
| + | Especially take attention for options like: | ||
| + | * deltaCacheSize = 10m | ||
| + | * packSizeLimit = 10m | ||
| + | * windowMemory = 10m | ||
| + | |||
| + | |||
| + | Command <code bash>git gc</code> and other cleaning commands requires whole repository to be read into memory. For big repos (like kernel.git) it requires to allocate over 8GB of RAM. | ||
| + | Compression of objects is also performed in RAM, then packs are written onto disc. | ||
| + | [[https://stackoverflow.com/questions/42175296/git-gc-uses-a-lot-of-memory-even-i-limited-it]] | ||
| + | |||
| + | |||
| + | To prevent touching existing packs and exhaust system memory paramter ''auto'' should be used. <code bash>git gc --auto</code> | ||
| + | Another possibility is to mark some packs as ''keep'' by creating .keep files. | ||
| + | |||
| + | Remove unreachable objects: | ||
| + | <code bash> | ||
| + | |||
| + | git count-objects -v | ||
| + | git gc --auto # this is enough to remove loose objects and repack repo | ||
| + | git count-objects -v | ||
| + | |||
| + | # more instruction | ||
| + | git repack -Ad # Remove dangling objects from packfiles | ||
| + | git prune # Remove dangling loose objects | ||
| + | git gc --aggressive --prune=now --force || rm -f .git/objects/*/tmp_* && rm -f .git/objects/*/.tmp-* | ||
| + | |||
| + | git count-objects -v | ||
| + | </code> | ||
