New --dirstat=lines mode, doing dirstat analysis based on diffstat This patch adds an alternative implementation of show_dirstat(), called show_dirstat_by_line(), which uses the more expensive diffstat analysis (as opposed to show_dirstat()'s own (relatively inexpensive) analysis) to derive the numbers from which the --dirstat output is computed. The alternative implementation is controlled by the new "lines" parameter to the --dirstat option (or the diff.dirstat config variable). For binary files, the diffstat analysis counts bytes instead of lines, so to prevent binary files from dominating the dirstat results, the byte counts for binary files are divided by 64 before being compared to their textual/line-based counterparts. This is a stupid and ugly - but very cheap - heuristic. In linux-2.6.git, running the three different --dirstat modes: time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null vs. time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null vs. time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null yields the following average runtimes on my machine: - "changes" (default): ~6.0 s - "lines": ~9.6 s - "files": ~0.1 s So, as expected, there's a considerable performance hit (~60%) by going through the full diffstat analysis as compared to the default "changes" analysis (obviously, "files" is much faster than both). As such, the "lines" mode is probably only useful if you really need the --dirstat numbers to be consistent with the numbers returned from the other --*stat options. The patch also includes documentation and tests for the new dirstat mode.

Improve error handling when parsing dirstat parameters When encountering errors or unknown tokens while parsing parameters to the --dirstat option, it makes sense to die() with an error message informing the user of which parameter did not make sense. However, when parsing the diff.dirstat config variable, we cannot simply die(), but should instead (after warning the user) ignore the erroneous or unrecognized parameter. After all, future Git versions might add more dirstat parameters, and using two different Git versions on the same repo should not cripple the older Git version just because of a parameter that is only understood by a more recent Git version. This patch fixes the issue by refactoring the dirstat parameter parsing so that parse_dirstat_params() keeps on parsing parameters, even if an earlier parameter was not recognized. When parsing has finished, it returns zero if all parameters were successfully parsed, and non-zero if one or more parameters were not recognized (with appropriate error messages appended to the 'errmsg' argument). The parse_dirstat_params() callers then decide (based on the return value from parse_dirstat_params()) whether to warn and ignore (in case of diff.dirstat), or to warn and die (in case of --dirstat). The patch also adds a couple of tests verifying the correct behavior of --dirstat and diff.dirstat in the face of unknown (possibly future) dirstat parameters.
