2011-06-30git skew: a tool to find how big a clock skew exists in the historyLibravatar Jeff King5-0/+54
> As you probably guessed from the specificity of the number, I wrote a > short program to actually traverse and find the worst skew. It takes > about 5 seconds to run (unsurprisingly, since it is doing the same full > traversal that we end up doing in the above numbers). So we could > "autoskew" by setting up the configuration on clone, and then > periodically updating it as part of "git gc". This patch doesn't implement auto-detection of skew, but is the program I used to calculate, and would provide the basis for such auto-detection. It would be interesting to see average skew numbers for popular repositories. You can run it as "git skew --all".

2011-06-11limit "contains" traversals based on commit timestampLibravatar Jeff King1-3/+33
When looking for commits that contain other commits (e.g., via "git tag --contains"), we can end up traversing useless portions of the graph. For example, if I am looking for a tag that contains a commit made last week, there is not much point in traversing portions of the history graph made five years ago. This optimization can provide massive speedups. For example, doing "git tag --contains HEAD~200" in the linux-2.6 repository goes from: real 0m5.302s user 0m5.116s sys 0m0.184s to: real 0m0.030s user 0m0.020s sys 0m0.008s The downside is that we will no longer find some answers in the face of extreme clock skew, as we will stop the traversal early when seeing commits skewed too far into the past. Name-rev already implements a similar optimization, using a "slop" of one day to allow for a certain amount of clock skew in commit timestamps. This patch introduces a "core.clockskew" variable, which allows specifying the allowable amount of clock skew in seconds. For safety, it defaults to "none", causing a full traversal (i.e., no change in behavior from previous versions).

2011-06-11tag: speed up --contains calculationLibravatar Jeff King1-1/+45
When we want to know if commit A contains commit B (or any one of a set of commits, B through Z), we generally calculate the merge bases and see if B is a merge base of A (or for a set, if any of the commits B through Z have that property). When we are going to check a series of commits A1 through An to see whether each contains B (e.g., because we are deciding which tags to show with "git tag --contains"), we do a series of merge base calculations. This can be very expensive, as we repeat a lot of traversal work. Instead, let's leverage the fact that we are going to use the same --contains list for each tag, and mark areas of the commit graph is definitely containing those commits, or definitely not containing those commits. Later tags can then stop traversing as soon as they see a previously calculated answer. This sped up "git tag --contains HEAD~200" in the linux-2.6 repository from: real 0m15.417s user 0m15.197s sys 0m0.220s to: real 0m5.329s user 0m5.144s sys 0m0.184s Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
