Bug #: 50840
Summary: gcc_update can't find SVN revision in Mercurial tree
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: si...@pushface.org
gcc_update tries to update gcc/REVISION with the SVN revision corresponding to
the Hg revision that's been checked out. With a Mercurial clone of trunk, this
fails, because gcc_update looks for the SVN revision in the extra: line "as
stored by hg convert" (line 331ff)
revision=`$GCC_HG log --debug -r$parents | \
sed -ne "/^extra:.*convert_revision=svn:/ {
s%^.*@%%
p
}"`
It looks as though "hg convert" has stopped storing the SVN revision:
$ hg log --debug -r104489
