See DELTA ISLANDS + below. + + +DELTA ISLANDS +------------- + +When possible, `pack-objects` tries to reuse existing on-disk deltas to +avoid having to search for new ones on the fly. This is an important +optimization for serving fetches, because it means the server can avoid +inflating most objects at all and just send the bytes directly from +disk. This optimization can't work when an object is stored as a delta +against a base which the receiver does not have (and which we are not +already sending). In that case the server "breaks" the delta and has to +find a new one, which has a high CPU cost. Therefore it's important for +performance that the set of objects in on-disk delta relationships match +what a client would fetch. + +In a normal repository, this tends to work automatically. The objects +are mostly reachable from the branches and tags, and that's what clients +fetch. Any deltas we find on the server are likely to be between objects +the client has or will have. + +But in some repository setups, you may have several related but separate +groups of ref tips, with clients tending to fetch those groups +independently. For example, imagine that you are hosting several "forks" +of a repository in a single shared object store, and letting clients +view them as separate repositories through `GIT_NAMESPACE` or separate +repos using the alternates mechanism. A naive repack may find that the +optimal delta for an object is against a base that is only found in +another fork. But when a client fetches, they will not have the base +object, and we'll have to find a new delta on the fly. + +A similar situation may exist if you have many refs outside of +`refs/heads/` and `refs/tags/` that point to related objects (e.g., +`refs/pull` or `refs/changes` used by some hosting providers). By +default, clients fetch only heads and tags, and deltas against objects +found only in those other groups cannot be sent as-is. + +Delta islands solve this problem by allowing you to group your refs into +distinct "islands". Pack-objects computes which objects are reachable +from which islands, and refuses to make a delta from an object `A` +against a base which is not present in all of `A`'s islands. This +results in slightly larger packs (because we miss some delta +opportunities), but guarantees that a fetch of one island will not have +to recompute deltas on the fly due to crossing island boundaries. + +When repacking with delta islands the delta window tends to get +clogged with candidates that are forbidden by the config. Repacking +with a big --window helps (and doesn't take as long as it otherwise +might because we can reject some object pairs based on islands before +doing any computation on the content). + +Islands are configured via the `pack.island` option, which can be +specified multiple times. Each value is a left-anchored regular +expressions matching refnames. For example: + +------------------------------------------- +[pack] +island = refs/heads/ +island = refs/tags/ +------------------------------------------- + +puts heads and tags into an island (whose name is the empty string; see +below for more on naming). Any refs which do not match those regular +expressions (e.g., `refs/pull/123`) is not in any island. Any object +which is reachable only from `refs/pull/` (but not heads or tags) is +therefore not a candidate to be used as a base for `refs/heads/`. + +Refs are grouped into islands based on their "names", and two regexes +that produce the same name are considered to be in the same +island. The names are computed from the regexes by concatenating any +capture groups from the regex, with a '-' dash in between. (And if +there are no capture groups, then the name is the empty string, as in +the above example.) This allows you to create arbitrary numbers of +islands.

To do this, the labels on the conflict +markers are stripped, and the common ancestor version is removed. The above +examples would both result in the following normalized conflict: + + <<<<<<< + B + ======= + C + >>>>>>> + +Sorting hunks +~~~~~~~~~~~~~ + +As before, lets imagine that a common ancestor had a file with line A +its early part, and line X in its late part.

The former +would say "A became B or C, what now?" while the latter would say "A +became C or B, what now?" + +As a reminder, the act of merging AC into ABAC and resolving the +conflict to leave line D means that the user declares: + + After examining what branches AB and AC did, I believe that + making line A into line D is the best thing to do that is + compatible with what AB and AC wanted to do. + +So the conflict we would see when merging AB into ACAB should be +resolved the same way---it is the resolution that is in line with that +declaration. + +Imagine that similarly previously a branch XYXZ was forked from XY, +and XZ was merged into it, and resolved "X became Y or Z" into "X +became W". + +Now, if a branch ABXY was forked from AB and then merged XY, then ABXY +would have line B in its early part and line Y in its later part. +Such a merge would be quite clean. We can construct 4 combinations +using these four branches ((AB, AC) x (XY, XZ)). + +Merging ABXY and ACXZ would make "an early A became B or C, a late X +became Y or Z" conflict, while merging ACXY and ABXZ would make "an +early A became C or B, a late X became Y or Z". We can see there are +4 combinations of ("B or C", "C or B") x ("X or Y", "Y or X"). + +By sorting, the conflict is given its canonical name, namely, "an +early part became B or C, a late part becames X or Y", and whenever +any of these four patterns appear, and we can get to the same conflict +and resolution that we saw earlier. + +Without the sorting, we'd have to somehow find a previous resolution +from combinatorial explosion. + +Conflict ID calculation +~~~~~~~~~~~~~~~~~~~~~~~ + +Once the conflict normalization is done, the conflict ID is calculated +as the sha1 hash of the conflict hunks appended to each other, +separated by <NUL> characters. The conflict markers are stripped out +before the sha1 is calculated. So in the example above, where we +merge branch AC which changes line A to line C, into branch AB, which +changes line A to line C, the conflict ID would be +SHA1('B<NUL>C<NUL>'). + +If there are multiple conflicts in one file, the sha1 is calculated +the same way with all hunks appended to each other, in the order in +which they appear in the file, separated by a <NUL> character. + +Nested conflicts +~~~~~~~~~~~~~~~~ + +Nested conflicts are handled very similarly to "simple" conflicts. +Similar to simple conflicts, the conflict is first normalized by +stripping the labels from conflict markers, stripping the common ancestor +version, and the sorting the conflict hunks, both for the outer and the +inner conflict.
