Currently the commit message only records +which operation triggered the update, and the commit authorship is +determined according to the usual rules (see linkgit:git-commit[1]). +These details may change in the future. + +It is also permitted for a notes ref to point directly to a tree +object, in which case the history of the notes can be read with +`git log -p -g <refname>`. + + +NOTES MERGE STRATEGIES +---------------------- + +The default notes merge strategy is "manual", which checks out +conflicting notes in a special work tree for resolving notes conflicts +(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the +conflicts in that work tree. +When done, the user can either finalize the merge with +'git notes merge --commit', or abort the merge with +'git notes merge --abort'. + +"ours" automatically resolves conflicting notes in favor of the local +version (i.e. the current notes ref). + +"theirs" automatically resolves notes conflicts in favor of the remote +version (i.e. the given notes ref being merged into the current notes +ref). + +"union" automatically resolves notes conflicts by concatenating the +local and remote versions. + +"cat_sort_uniq" is similar to "union", but in addition to concatenating +the local and remote versions, this strategy also sorts the resulting +lines, and removes duplicate lines from the result. This is equivalent +to applying the "cat | sort | uniq" shell pipeline to the local and +remote versions.

If such a URL is encountered directly on the +command line, the first argument is the same as the second, and if it +is encountered in a configured remote, the first argument is the name +of that remote. + +A URL of the form '<transport>::<address>' explicitly instructs git to +invoke 'git remote-<transport>' with '<address>' as the second +argument. If such a URL is encountered directly on the command line, +the first argument is '<address>', and if it is encountered in a +configured remote, the first argument is the name of that remote. + +Additionally, when a configured remote has 'remote.<name>.vcs' set to +'<transport>', git explicitly invokes 'git remote-<transport>' with +'<name>' as the first argument.

If you want to look at commits made during - certain times, see `--since` and `--until`. - -* A ref followed by the suffix '@' with an ordinal specification - enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify - the n-th prior value of that ref. For example 'master@\{1\}' - is the immediate prior value of 'master' while 'master@\{5\}' - is the 5th prior value of 'master'. This suffix may only be used - immediately following a ref name and the ref must have an existing - log ($GIT_DIR/logs/<ref>). - -* You can use the '@' construct with an empty ref part to get at a - reflog of the current branch. For example, if you are on the - branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'. - -* The special construct '@\{-<n>\}' means the <n>th branch checked out - before the current one. - -* A suffix '{caret}' to a revision parameter means the first parent of - that commit object. '{caret}<n>' means the <n>th parent (i.e. - 'rev{caret}' - is equivalent to 'rev{caret}1'). As a special rule, - 'rev{caret}0' means the commit itself and is used when 'rev' is the - object name of a tag object that refers to a commit object. - -* A suffix '{tilde}<n>' to a revision parameter means the commit - object that is the <n>th generation grand-parent of the named - commit object, following only the first parent. I.e. rev~3 is - equivalent to rev{caret}{caret}{caret} which is equivalent to - rev{caret}1{caret}1{caret}1. See below for a illustration of - the usage of this form. - -* A suffix '{caret}' followed by an object type name enclosed in - brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object - could be a tag, and dereference the tag recursively until an - object of that type is found or the object cannot be - dereferenced anymore (in which case, barf). `rev{caret}0` - introduced earlier is a short-hand for `rev{caret}\{commit\}`. - -* A suffix '{caret}' followed by an empty brace pair - (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag, - and dereference the tag recursively until a non-tag object is - found. - -* A colon, followed by a slash, followed by a text: this names - a commit whose commit message starts with the specified text. - This name returns the youngest matching commit which is - reachable from any ref. If the commit message starts with a - '!', you have to repeat that; the special sequence ':/!', - followed by something else than '!' is reserved for now. - -* A suffix ':' followed by a path; this names the blob or tree - at the given path in the tree-ish object named by the part - before the colon. - -* A colon, optionally followed by a stage number (0 to 3) and a - colon, followed by a path; this names a blob object in the - index at the given path. Missing stage number (and the colon - that follows it) names a stage 0 entry. During a merge, stage - 1 is the common ancestor, stage 2 is the target branch's version - (typically the current branch), and stage 3 is the version from - the branch being merged. - -Here is an illustration, by Jon Loeliger.

When you have two commits `r1` and `r2` (named according -to the syntax explained in SPECIFYING REVISIONS above), you can ask -for commits that are reachable from r2 excluding those that are reachable -from r1 by `{caret}r1 r2` and it can be written as `r1..r2`. - -A similar notation `r1\...r2` is called symmetric difference -of `r1` and `r2` and is defined as -`r1 r2 --not $(git merge-base --all r1 r2)`. -It is the set of commits that are reachable from either one of -`r1` or `r2` but not from both. - -Two other shorthands for naming a set that is formed by a commit -and its parent commits exist.

This suffix may only be + used immediately following a ref name and the ref must have an + existing log ($GIT_DIR/logs/<ref>). Note that this looks up the state + of your *local* ref at a given time; e.g., what was in your local + `master` branch last week. If you want to look at commits made during + certain times, see `--since` and `--until`. + +* A ref followed by the suffix '@' with an ordinal specification + enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify + the n-th prior value of that ref. For example 'master@\{1\}' + is the immediate prior value of 'master' while 'master@\{5\}' + is the 5th prior value of 'master'. This suffix may only be used + immediately following a ref name and the ref must have an existing + log ($GIT_DIR/logs/<ref>). + +* You can use the '@' construct with an empty ref part to get at a + reflog of the current branch. For example, if you are on the + branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'. + +* The special construct '@\{-<n>\}' means the <n>th branch checked out + before the current one. + +* The suffix '@\{upstream\}' to a ref (short form 'ref@\{u\}') refers to + the branch the ref is set to build on top of. Missing ref defaults + to the current branch. + +* A suffix '{caret}' to a revision parameter (e.g. 'HEAD{caret}') means the first parent of + that commit object. '{caret}<n>' means the <n>th parent (i.e. + 'rev{caret}' + is equivalent to 'rev{caret}1'). As a special rule, + 'rev{caret}0' means the commit itself and is used when 'rev' is the + object name of a tag object that refers to a commit object. + +* A suffix '{tilde}<n>' to a revision parameter means the commit + object that is the <n>th generation grand-parent of the named + commit object, following only the first parent. I.e. rev~3 is + equivalent to rev{caret}{caret}{caret} which is equivalent to + rev{caret}1{caret}1{caret}1. See below for a illustration of + the usage of this form. + +* A suffix '{caret}' followed by an object type name enclosed in + brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object + could be a tag, and dereference the tag recursively until an + object of that type is found or the object cannot be + dereferenced anymore (in which case, barf). `rev{caret}0` + introduced earlier is a short-hand for `rev{caret}\{commit\}`. + +* A suffix '{caret}' followed by an empty brace pair + (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag, + and dereference the tag recursively until a non-tag object is + found. + +* A suffix '{caret}' to a revision parameter followed by a brace + pair that contains a text led by a slash (e.g. `HEAD^{/fix nasty bug}`): + this is the same as `:/fix nasty bug` syntax below except that + it returns the youngest matching commit which is reachable from + the ref before '{caret}'. + +* A colon, followed by a slash, followed by a text (e.g. `:/fix nasty bug`): this names + a commit whose commit message matches the specified regular expression. + This name returns the youngest matching commit which is + reachable from any ref. If the commit message starts with a + '!', you have to repeat that; the special sequence ':/!', + followed by something else than '!' is reserved for now. + The regular expression can match any part of the commit message. To + match messages starting with a string, one can use e.g. `:/^foo`. + +* A suffix ':' followed by a path (e.g. `HEAD:README`); this names the blob or tree + at the given path in the tree-ish object named by the part + before the colon. + ':path' (with an empty part before the colon, e.g. `:README`) + is a special case of the syntax described next: content + recorded in the index at the given path. + A path starting with './' or '../' is relative to current working directory. + The given path will be converted to be relative to working tree's root directory. + This is most useful to address a blob or tree from a commit or tree that has + the same tree structure with the working tree. + +* A colon, optionally followed by a stage number (0 to 3) and a + colon, followed by a path (e.g. `:0:README`); this names a blob object in the + index at the given path. Missing stage number (and the colon + that follows it, e.g. `:README`) names a stage 0 entry.

To these commands, +specifying a single revision with the notation described in the +previous section means the set of commits reachable from that +commit, following the commit ancestry chain. + +To exclude commits reachable from a commit, a prefix `{caret}` +notation is used. E.g. `{caret}r1 r2` means commits reachable +from `r2` but exclude the ones reachable from `r1`. + +This set operation appears so often that there is a shorthand +for it. When you have two commits `r1` and `r2` (named according +to the syntax explained in SPECIFYING REVISIONS above), you can ask +for commits that are reachable from r2 excluding those that are reachable +from r1 by `{caret}r1 r2` and it can be written as `r1..r2`. + +A similar notation `r1\...r2` is called symmetric difference +of `r1` and `r2` and is defined as +`r1 r2 --not $(git merge-base --all r1 r2)`. +It is the set of commits that are reachable from either one of +`r1` or `r2` but not from both. + +Two other shorthands for naming a set that is formed by a commit +and its parent commits exist.
