[PATCH v3 5/5] sparse-checkout: reject arguments in cone-mode that look like patterns

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Elijah Newren <newren@xxxxxxxxx>

In sparse-checkout add/set under cone mode, the arguments passed are
supposed to be directories rather than gitignore-style patterns.
However, given the amount of effort spent in the manual discussing
patterns, it is easy for users to assume they need to pass patterns such
as
   /foo/*
or
   !/bar/*/
or perhaps they really do ignore the directory rule and specify a
random gitignore-style pattern like
   *.c

To help catch such mistakes, throw an error if any of the positional
arguments:
  * starts with any of '/!'
  * contains any of '*\?[]'

Inform users they can pass --skip-checks if they have a directory that
really does have such special characters in its name.
