Hi! The monotonically increasing revision ids need to be globally unique, so they should only identify commits that were committed to the upstream repo to its master or releases/gcc-N branches. The alias could print something even for private branches or vendor branches etc., but if such an identifier is then used publicly, it will refer to something else.
Committed to trunk. Martin also suggested for git gcc-descr --full to also include date (commit date) in the string, so instead of r10-5998-g2588197b6c2175d7ef9f05a8636f58dfeab12b1d print r10-5998-20200116-g2588197b6c2175d7ef9f05a8636f58dfeab12b1d What do others think? The r10-5998 part in there is still needed to be the unique monotonically increasing identifier, the rest is something that can be derived from it, but e.g. in bugzilla the date could provide extra helpful information (which can be seen if one follows the link obviously). In addition to adjusting gcc-git-customization.sh, git-hooks we'd need to update the redirects and ask Frederic to update bugzilla URLization too. 2020-01-16 Jakub Jelinek <ja...@redhat.com> * gcc-git-customization.sh: Verify the id to be printed is ancestor of the corresponding remote release branch (or master), otherwise print nothing. --- contrib/gcc-git-customization.sh.jj 2020-01-15 14:28:26.996758773 +0100 +++ contrib/gcc-git-customization.sh 2020-01-16 12:27:46.734690164 +0100 @@ -22,7 +22,7 @@ git config alias.svn-rev '!f() { rev=$1; # Add git commands to convert git commit to monotonically increasing revision number # and vice versa -git config alias.gcc-descr \!"f() { if test \${1:-no} = --full; then r=\$(git describe --all --abbrev=40 --match 'basepoints/gcc-[0-9]*' \${2:-master} | sed -n 's,^\\(tags/\\)\\?basepoints/gcc-,r,p'); expr match \${r:-no} '^r[0-9]\\+\$' >/dev/null && r=\${r}-0-g\$(git rev-parse \${2:-master}); test -n \$r && echo \${r}; else git describe --all --match 'basepoints/gcc-[0-9]*' \${1:-master} | sed -n 's,^\\(tags/\\)\\?basepoints/gcc-\\([0-9]\\+\\)-\\([0-9]\\+\\)-g[0-9a-f]*\$,r\\2-\\3,p;s,^\\(tags/\\)\\?basepoints/gcc-\\([0-9]\\+\\)\$,r\\2-0,p'; fi; }; f" +git config alias.gcc-descr \!"f() { if test \${1:-no} = --full; then c=\${2:-master}; r=\$(git describe --all --abbrev=40 --match 'basepoints/gcc-[0-9]*' \$c | sed -n 's,^\\(tags/\\)\\?basepoints/gcc-,r,p'); expr match \${r:-no} '^r[0-9]\\+\$' >/dev/null && r=\${r}-0-g\$(git rev-parse \${2:-master}); else c=\${1:-master}; r=\$(git describe --all --match 'basepoints/gcc-[0-9]*' \$c | sed -n 's,^\\(tags/\\)\\?basepoints/gcc-\\([0-9]\\+\\)-\\([0-9]\\+\\)-g[0-9a-f]*\$,r\\2-\\3,p;s,^\\(tags/\\)\\?basepoints/gcc-\\([0-9]\\+\\)\$,r\\2-0,p'); fi; if test -n \$r; then o=\$(git config --get gcc-config.upstream); rr=\$(echo \$r | sed -n 's,^r\\([0-9]\\+\\)-[0-9]\\+\\(-g[0-9a-f]\\+\\)\\?\$,\\1,p'); if git rev-parse --verify --quiet \${o:-origin}/releases/gcc-\$rr >/dev/null; then m=releases/gcc-\$rr; else m=master; fi; git merge-base --is-ancestor \$c \${o:-origin}/\$m && \echo \${r}; fi; }; f" git config alias.gcc-undescr \!"f() { o=\$(git config --get gcc-config.upstream); r=\$(echo \$1 | sed -n 's,^r\\([0-9]\\+\\)-[0-9]\\+\$,\\1,p'); n=\$(echo \$1 | sed -n 's,^r[0-9]\\+-\\([0-9]\\+\\)\$,\\1,p'); test -z \$r && echo Invalid id \$1 && exit 1; h=\$(git rev-parse --verify --quiet \${o:-origin}/releases/gcc-\$r); test -z \$h && h=\$(git rev-parse --verify --quiet \${o:-origin}/master); p=\$(git describe --all --match 'basepoints/gcc-'\$r \$h | sed -n 's,^\\(tags/\\)\\?basepoints/gcc-[0-9]\\+-\\([0-9]\\+\\)-g[0-9a-f]*\$,\\2,p;s,^\\(tags/\\)\\?basepoints/gcc-[0-9]\\+\$,0,p'); git rev-parse --verify \$h~\$(expr \$p - \$n); }; f" # Make diff on MD files use "(define" as a function marker.
