   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. If a "version.i" is present, for example when building
  24 ## from a distribution tarball, get the git_version using grep.
  25 ##
  26 ## Fetch the EXTRA_VERSION_NAME define from "version/extra_version_name" and output it
  27 ## to "version.i.tmp".
  28 ##
  29 ## Fetch the EXTRA_VERSION_DESCRIPTION define from "version/extra_version_description",
  30 ## sanitize and format it with a sed script to replace all non-alpha-numeric values
  31 ## with "-" and join all lines by replacing "\n" with litteral string c-style "\n\t" and
  32 ## output it to "version.i.tmp".
  33 ##
  34 ## Repeat the same logic for the "version/extra_patches" directory.
  35 ## Data fetched from "version/extra_patches" must be sanitized and
  36 ## formatted.
  37 ## The data is fetched using "ls" with an ignore pattern for the README file.
  38 ## The sanitize step uses sed with a script to replace all
  39 ## non-alpha-numeric values, except " " (space), to "-".
  40 ## The formatting step uses sed with a script to join all lines
  41 ## by replacing "\n" with litteral string c-style "\n\t".
  42 ##
  43 ## If we don't have a "version.i" or we have both files (version.i, version.i.tmp)
  44 ## and they are different, copy "version.i.tmp" over "version.i".
  45 ## This way the dependent targets are only rebuilt when the git version
  46 ## string or either one of extra version string change.
