#testcases skip-detection fail-if-detected Test situations that "should" only be reproducible: - on networked filesystems, or - user using `hg debuglocks` to eliminate the lock file, or - something (that doesn't respect the lock file) writing to the .hg directory while we're running $ hg init a $ cd a $ cat > "$TESTTMP_FORWARD_SLASH/waitlock_editor.sh" <<EOF > [ -n "\${WAITLOCK_ANNOUNCE:-}" ] && touch "\${WAITLOCK_ANNOUNCE}" > f="\${WAITLOCK_FILE}" > start=\`date +%s\` > timeout=5 > "$RUNTESTDIR_FORWARD_SLASH/testlib/wait-on-file" "\$timeout" "\$f" > if [ \$# -gt 1 ]; then > cat "\$@" > fi > EOF Things behave differently if we don't already have a 00changelog.i file when this all starts, so let's make one. $ echo r0 > r0 $ hg commit -qAm 'r0' Start an hg commit that will take a while $ EDITOR_STARTED="$TESTTMP_FORWARD_SLASH/a/.editor_started" $ MISCHIEF_MANAGED="$TESTTMP_FORWARD_SLASH/a/.mischief_managed" $ JOBS_FINISHED="$TESTTMP_FORWARD_SLASH/a/.jobs_finished" #if fail-if-detected $ cat >> .hg/hgrc << EOF > [debug] > revlog.verifyposition.changelog = fail > EOF #endif $ cat >> .hg/hgrc << EOF > [ui] > editor=sh $TESTTMP_FORWARD_SLASH/waitlock_editor.sh > EOF $ echo foo > foo $ (unset HGEDITOR; > WAITLOCK_ANNOUNCE="${EDITOR_STARTED}" \ > WAITLOCK_FILE="${MISCHIEF_MANAGED}" \ > hg commit -qAm 'r1 (foo)' --edit foo > .foo_commit_out 2>&1 ; touch "${JOBS_FINISHED}") & Wait for the "editor" to actually start $ sh "$RUNTESTDIR_FORWARD_SLASH/testlib/wait-on-file" 5 "${EDITOR_STARTED}" $ cat >> .hg/hgrc << EOF > [ui] > editor= > EOF Break the locks, and make another commit. $ hg debuglocks -LW $ echo bar > bar $ hg commit -qAm 'r2 (bar)' bar $ hg debugrevlogindex -c rev linkrev nodeid p1 p2 0 0 222799e2f90b 000000000000 000000000000 1 1 6f124f6007a0 222799e2f90b 000000000000 Awaken the editor from that first commit $ touch "${MISCHIEF_MANAGED}" And wait for it to finish $ WAITLOCK_FILE="${JOBS_FINISHED}" sh "$TESTTMP_FORWARD_SLASH/waitlock_editor.sh" #if skip-detection (Ensure there was no output) $ cat .foo_commit_out And observe a corrupted repository -- rev 2's linkrev is 1, which should never happen for the changelog (the linkrev should always refer to itself). $ hg debugrevlogindex -c rev linkrev nodeid p1 p2 0 0 222799e2f90b 000000000000 000000000000 1 1 6f124f6007a0 222799e2f90b 000000000000 2 1 ac80e6205bb2 222799e2f90b 000000000000 #endif #if fail-if-detected $ cat .foo_commit_out transaction abort! rollback completed note: commit message saved in .hg/last-message.txt note: use 'hg commit --logfile .hg/last-message.txt --edit' to reuse it abort: 00changelog.i: file cursor at position 249, expected 121 And no corruption in the changelog. $ hg debugrevlogindex -c rev linkrev nodeid p1 p2 0 0 222799e2f90b 000000000000 000000000000 1 1 6f124f6007a0 222799e2f90b 000000000000 (missing-correct-output !)
