        // guaranteed to work.

Example 2 with PatchSetData

use of com.google.gerrit.server.change.WalkSorter.PatchSetData in project gerrit by GerritCodeReview.

the class SubmittedTogether method sort.

private ImmutableList<ChangeData> sort(List<ChangeData> cds, int hidden) throws IOException {
    if (cds.size() <= 1 && hidden == 0) {
        // repo just to fill out the commit field in PatchSetData.

    long numProjects = cds.stream().map(ChangeData::project).count();
    if (numProjects == numProjectsDistinct || numProjectsDistinct > 5) {
        // which would make WalkSorter too expensive for this call.
        return cds.stream().sorted(COMPARATOR).collect(toImmutableList());
    }
    // Perform more expensive walk-sort.
    ImmutableList.Builder<ChangeData> sorted = ImmutableList.builderWithExpectedSize(cds.size());
    for (PatchSetData psd : sorter.get().sort(cds)) {
        sorted.add(psd.data());
    }
    return sorted.build();
}

Example 3 with PatchSetData

use of com.google.gerrit.server.change.WalkSorter.PatchSetData in project gerrit by GerritCodeReview.
