📂 Minimize allocations in Go

A collection of tips for when you need to minimize the number of allocations in your Go programs.

Use the go profiler to identify which parts of your program are responsible for most allocations.

Caution

Never apply these tricks blindly (i.e. without measuring the actual performance benefit/impact).

Smart redirect for branch-less URLs

URLs of the form https://github.com/user/repo/something/somethingelse should redirect to https://github.com/user/repo/defaultbranch/something/somethingelse if:

• something does not match a branch name
• something/somethingelse exists in defaultbranch

Smart redirect for renamed files

URLs of the form https://github.com/user/repo/branch/something/somethingelse should redirect to https://github.com/user/repo/branch/somethingnew if:

• something/somethingelse else does not currently exist in branch
