  20 # The following section is based on a similar feature in LTTng-tools.

  22 ##
  23 ## This target generates an include file that contains the git version
  24 ## string of the current branch, it must be continuously updated when
  25 ## we build in the git repo and shipped in dist tarballs to reflect the
  26 ## status of the tree when it was generated. If the tree is clean and
  27 ## the current commit is tag a starting with "v", consider this a
  28 ## release version and set an empty git version.
  29 ##
  30 ## Here is what the inline script does:
  31 ##
  32 ## First, delete any stale "version.i.tmp" file.
  33 ##
  34 ## If "bootstrap" and ".git" exists in the top source directory and the git
  35 ## executable is available, get the current git version string in the form:
  36 ##
  37 ##  "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty)
  38 ##
  39 ## And store it in "version.i.tmp", if the current commit is tagged, the tag
  40 ## starts with "v" and the tree is clean, consider this a release version and
  41 ## overwrite the git version with an empty string in "version.i.tmp".
  42 ##
  43 ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty
  44 ## string as a failover. If a "version.i" is present, for example when building
  45 ## from a distribution tarball, get the git_version using grep.
  46 ##
  47 ## Fetch the BT_VERSION_EXTRA_NAME define from "version/extra_version_name" and output it
  48 ## to "version.i.tmp".
  49 ##
  50 ## Fetch the BT_VERSION_EXTRA_DESCRIPTION define from "version/extra_version_description",
  51 ## sanitize and format it with a sed script to replace all non-alpha-numeric values
  52 ## with "-" and join all lines by replacing "\n" with litteral string c-style "\n" and
  53 ## output it to "version.i.tmp".
  54 ##
  55 ## Repeat the same logic for the "version/extra_patches" directory.
  56 ## Data fetched from "version/extra_patches" must be sanitized and
  57 ## formatted.
  58 ## The data is fetched using "ls" with an ignore pattern for the README.adoc file.
  59 ## The sanitize step uses sed with a script to replace all
  60 ## non-alpha-numeric values, except " " (space), to "-".
  61 ## The formatting step uses sed with a script to join all lines
  62 ## by replacing "\n" with litteral string c-style "\n".
  63 ##
  64 ## If we don't have a "version.i" or we have both files (version.i, version.i.tmp)
  65 ## and they are different, copy "version.i.tmp" over "version.i".
  66 ## This way the dependent targets are only rebuilt when the git version
  67 ## string or either one of extra version string change.
