   1 ##
   2 ## This target generates an include file that contains the git version
   3 ## string of the current branch, it must be continuously updated when
   4 ## we build in the git repo and shipped in dist tarballs to reflect the
   5 ## status of the tree when it was generated. If the tree is clean and
   6 ## the current commit is tag a starting with "v", consider this a
   7 ## release version and set an empty git version.
   8 ##
   9 ## Here is what the inline script does:
  10 ##
  11 ## First, delete any stale "version.i.tmp" file.
  12 ##
  13 ## If "bootstrap" and ".git" exists in the top source directory and the git
  14 ## executable is available, get the current git version string in the form:
  15 ##
  16 ##  "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty)
  17 ##
  18 ## And store it in "version.i.tmp", if the current commit is tagged, the tag
  19 ## starts with "v" and the tree is clean, consider this a release version and
  20 ## overwrite the git version with an empty string in "version.i.tmp".
  21 ##
  22 ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty
  23 ## string as a failover.
  24 ##
  25 ## If we don't have a "version.i" or we have both files and they are different,
  26 ## copy "version.i.tmp" over "version.i". This way the dependent targets are
  27 ## only rebuilt when the version string changes.
