Bug 516644 – mercurial.eclass: Provide a variable EHG_CHECKOUT_DIR to override checkout destination

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Matthias Maier 2014-07-07 21:55:59 UTC]

The git eclass has a variable EGIT_SOURCEDIR defaulting to ${S} to explicitly override the checkout location.

This is extremely useful for repositories where the actual sources reside under a subdirectory. The normal approach is to set ${S} to the full path to the appropriate subdirectory:

  EHG_REPO_URI="[...]"
  S="${WORKDIR}/${P}/sudirectory_containing_sources"

But with this, the mercurial eclass tries to copy the checkout to ${S} and, consequently, this approach fails. With an EHG_SOURCEDIR variable that explicitly sets the checkout location this would be easily possible:

  EHG_REPO_URI="[...]"
  EHG_SOURCEDIR="${WORKDIR}/${P}"
  S="${WORKDIR}/${P}/sudirectory_containing_sources"

Without, I see no viable solution for this problem except for manual movement of directories in the src_prepare stage, which is clumsy.

Reproducible: Always

One could call mercurial_fetch in src_unpack, but it might be more useful and consistent with git-r3 to add a EGIT_CHECKOUT_DIR variable.

Have a look if you like that.
