|
Ancestor
|
|
|
Any changeset that can be reached by an unbroken chain of parent
|
|
|
changesets from a given changeset. More precisely, the ancestors
|
|
|
of a changeset can be defined by two properties: a parent of a
|
|
|
changeset is an ancestor, and a parent of an ancestor is an
|
|
|
ancestor. See also: 'Descendant'.
|
|
|
|
|
|
Branch
|
|
|
(Noun) A child changeset that has been created from a parent that
|
|
|
is not a head. These are known as topological branches, see
|
|
|
'Branch, topological'. If a topological branch is named, it becomes
|
|
|
a named branch. If a topological branch is not named, it becomes
|
|
|
an anonymous branch. See 'Branch, anonymous' and 'Branch, named'.
|
|
|
|
|
|
Branches may be created when changes are pulled from or pushed to
|
|
|
a remote repository, since new heads may be created by these
|
|
|
operations. Note that the term branch can also be used informally
|
|
|
to describe a development process in which certain development is
|
|
|
done independently of other development.This is sometimes done
|
|
|
explicitly with a named branch, but it can also be done locally,
|
|
|
using bookmarks or clones and anonymous branches.
|
|
|
|
|
|
Example: "The experimental branch".
|
|
|
|
|
|
(Verb) The action of creating a child changeset which results in
|
|
|
its parent having more than one child.
|
|
|
|
|
|
Example: "I'm going to branch at X".
|
|
|
|
|
|
Branch, anonymous
|
|
|
Every time a new child changeset is created from a parent that is not
|
|
|
a head and the name of the branch is not changed, a new anonymous
|
|
|
branch is created.
|
|
|
|
|
|
Branch, closed
|
|
|
A named branch whose branch heads have all been closed.
|
|
|
|
|
|
Branch, default
|
|
|
The branch assigned to a changeset when no name has previously been
|
|
|
assigned.
|
|
|
|
|
|
Branch head
|
|
|
See 'Head, branch'.
|
|
|
|
|
|
Branch, named
|
|
|
A collection of changesets which have the same branch name. By
|
|
|
default, children of a changeset in a named branch belong to the
|
|
|
same named branch. A child can be explicitly assigned to a
|
|
|
different branch. See :hg:`help branch`, :hg:`help branches` and
|
|
|
:hg:`commit --close-branch` for more information on managing
|
|
|
branches.
|
|
|
|
|
|
Named branches can be thought of as a kind of namespace, dividing
|
|
|
the collection of changesets that comprise the repository into a
|
|
|
collection of disjoint subsets. A named branch is not necessarily
|
|
|
a topological branch. If a new named branch is created from the
|
|
|
head of another named branch, or the default branch, but no
|
|
|
further changesets are added to that previous branch, then that
|
|
|
previous branch will be a branch in name only.
|
|
|
|
|
|
Branch tip
|
|
|
See 'Tip, branch'.
|
|
|
|
|
|
Branch, topological
|
|
|
Every time a new child changeset is created from a parent that is
|
|
|
not a head, a new topological branch is created. If a topological
|
|
|
branch is named, it becomes a named branch. If a topological
|
|
|
branch is not named, it becomes an anonymous branch of the
|
|
|
current, possibly default, branch.
|
|
|
|
|
|
Changelog
|
|
|
A record of the changesets in the order in which they were added
|
|
|
to the repository. This includes details such as changeset id,
|
|
|
author, commit message, date, and list of changed files.
|
|
|
|
|
|
Changeset
|
|
|
A snapshot of the state of the repository used to record a change.
|
|
|
|
|
|
Changeset, child
|
|
|
The converse of parent changeset: if P is a parent of C, then C is
|
|
|
a child of P. There is no limit to the number of children that a
|
|
|
changeset may have.
|
|
|
|
|
|
Changeset id
|
|
|
A SHA-1 hash that uniquely identifies a changeset. It may be
|
|
|
represented as either a "long" 40-byte hexadecimal string, or a
|
|
|
"short" 12-byte hexadecimal string.
|
|
|
|
|
|
Changeset, merge
|
|
|
A changeset with two parents. This occurs when a merge is
|
|
|
committed.
|
|
|
|
|
|
Changeset, parent
|
|
|
A revision upon which a child changeset is based. Specifically, a
|
|
|
parent changeset of a changeset C is a changeset whose node
|
|
|
immediately precedes C in the DAG. Changesets have at most two
|
|
|
parents.
|
|
|
|
|
|
Checkout
|
|
|
(Noun) The working directory being updated to a specific
|
|
|
revision. This use should probably be avoided where possible, as
|
|
|
changeset is much more appropriate than checkout in this context.
|
|
|
|
|
|
Example: "I'm using checkout X."
|
|
|
|
|
|
(Verb) Updating the working directory to a specific changeset. See
|
|
|
:hg:`help update`.
|
|
|
|
|
|
Example: "I'm going to check out changeset X."
|
|
|
|
|
|
Child changeset
|
|
|
See 'Changeset, child'.
|
|
|
|
|
|
Close changeset
|
|
|
See 'Changeset, close'.
|
|
|
|
|
|
Closed branch
|
|
|
See 'Branch, closed'.
|
|
|
|
|
|
Clone
|
|
|
(Noun) An entire or partial copy of a repository. The partial
|
|
|
clone must be in the form of a revision and its ancestors.
|
|
|
|
|
|
Example: "Is your clone up to date?".
|
|
|
|
|
|
(Verb) The process of creating a clone, using :hg:`clone`.
|
|
|
|
|
|
Example: "I'm going to clone the repository".
|
|
|
|
|
|
Closed branch head
|
|
|
See 'Head, closed branch'.
|
|
|
|
|
|
Commit
|
|
|
(Noun) A synonym for changeset.
|
|
|
|
|
|
Example: "Is the bug fixed in your recent commit?"
|
|
|
|
|
|
(Verb) The act of recording changes to a repository. When files
|
|
|
are committed in a working directory, Mercurial finds the
|
|
|
differences between the committed files and their parent
|
|
|
changeset, creating a new changeset in the repository.
|
|
|
|
|
|
Example: "You should commit those changes now."
|
|
|
|
|
|
Cset
|
|
|
A common abbreviation of the term changeset.
|
|
|
|
|
|
DAG
|
|
|
The repository of changesets of a distributed version control
|
|
|
system (DVCS) can be described as a directed acyclic graph (DAG),
|
|
|
consisting of nodes and edges, where nodes correspond to
|
|
|
changesets and edges imply a parent -> child relation. This graph
|
|
|
can be visualized by graphical tools such as :hg:`glog`
|
|
|
(graphlog). In Mercurial, the DAG is limited by the requirement
|
|
|
for children to have at most two parents.
|
|
|
|
|
|
Default branch
|
|
|
See 'Branch, default'.
|
|
|
|
|
|
Descendant
|
|
|
Any changeset that can be reached by a chain of child changesets
|
|
|
from a given changeset. More precisely, the descendants of a
|
|
|
changeset can be defined by two properties: the child of a
|
|
|
changeset is a descendant, and the child of a descendant is a
|
|
|
descendant. See also: 'Ancestor'.
|
|
|
|
|
|
Diff
|
|
|
(Noun) The difference between the contents and attributes of files
|
|
|
in two changesets or a changeset and the current working
|
|
|
directory. The difference is usually represented in a standard
|
|
|
form called a "diff" or "patch". The "git diff" format is used
|
|
|
when the changes include copies, renames, or changes to file
|
|
|
attributes, none of which can be represented/handled by classic
|
|
|
"diff" and "patch".
|
|
|
|
|
|
Example: "Did you see my correction in the diff?"
|
|
|
|
|
|
(Verb) Diffing two changesets is the action of creating a diff or
|
|
|
patch.
|
|
|
|
|
|
Example: "If you diff with changeset X, you will see what I mean."
|
|
|
|
|
|
Directory, working
|
|
|
The working directory represents the state of the files tracked by
|
|
|
Mercurial, that will be recorded in the next commit. The working
|
|
|
directory initially corresponds to the snapshot at an existing
|
|
|
changeset, known as the parent of the working directory. See
|
|
|
'Parent, working directory'. The state may be modified by changes
|
|
|
to the files introduced manually or by a merge. The repository
|
|
|
metadata exists in the .hg directory inside the working directory.
|
|
|
|
|
|
Graph
|
|
|
See DAG and :hg:`help graphlog`.
|
|
|
|
|
|
Head
|
|
|
The term 'head' may be used to refer to both a branch head or a
|
|
|
repository head, depending on the context. See 'Head, branch' and
|
|
|
'Head, repository' for specific definitions.
|
|
|
|
|
|
Heads are where development generally takes place and are the
|
|
|
usual targets for update and merge operations.
|
|
|
|
|
|
Head, branch
|
|
|
A changeset with no descendants on the same named branch.
|
|
|
|
|
|
Head, closed branch
|
|
|
A changeset that marks a head as no longer interesting. The closed
|
|
|
head is no longer listed by :hg:`heads`. A branch is considered
|
|
|
closed when all its heads are closed and consequently is not
|
|
|
listed by :hg:`branches`.
|
|
|
|
|
|
Head, repository
|
|
|
A topological head which has not been closed.
|
|
|
|
|
|
Head, topological
|
|
|
A changeset with no children in the repository.
|
|
|
|
|
|
History, immutable
|
|
|
Once committed, changesets cannot be altered. Extensions which
|
|
|
appear to change history actually create new changesets that
|
|
|
replace existing ones, and then destroy the old changesets. Doing
|
|
|
so in public repositories can result in old changesets being
|
|
|
reintroduced to the repository.
|
|
|
|
|
|
History, rewriting
|
|
|
The changesets in a repository are immutable. However, extensions
|
|
|
to Mercurial can be used to alter the repository, usually in such
|
|
|
a way as to preserve changeset contents.
|
|
|
|
|
|
Immutable history
|
|
|
See 'History, immutable'.
|
|
|
|
|
|
Merge changeset
|
|
|
See 'Changeset, merge'.
|
|
|
|
|
|
Manifest
|
|
|
Each changeset has a manifest, which is the list of files that are
|
|
|
tracked by the changeset.
|
|
|
|
|
|
Merge
|
|
|
Used to bring together divergent branches of work. When you update
|
|
|
to a changeset and then merge another changeset, you bring the
|
|
|
history of the latter changeset into your working directory. Once
|
|
|
conflicts are resolved (and marked), this merge may be committed
|
|
|
as a merge changeset, bringing two branches together in the DAG.
|
|
|
|
|
|
Named branch
|
|
|
See 'Branch, named'.
|
|
|
|
|
|
Null changeset
|
|
|
The empty changeset. It is the parent state of newly-initialized
|
|
|
repositories and repositories with no checked out revision. It is
|
|
|
thus the parent of root changesets and the effective ancestor when
|
|
|
merging unrelated changesets. Can be specified by the alias 'null'
|
|
|
or by the changeset ID '000000000000'.
|
|
|
|
|
|
Parent
|
|
|
See 'Changeset, parent'.
|
|
|
|
|
|
Parent changeset
|
|
|
See 'Changeset, parent'.
|
|
|
|
|
|
Parent, working directory
|
|
|
The working directory parent reflects a virtual revision which is
|
|
|
the child of the changeset (or two changesets with an uncommitted
|
|
|
merge) shown by :hg:`parents`. This is changed with
|
|
|
:hg:`update`. Other commands to see the working directory parent
|
|
|
are :hg:`summary` and :hg:`id`. Can be specified by the alias ".".
|
|
|
|
|
|
Patch
|
|
|
(Noun) The product of a diff operation.
|
|
|
|
|
|
Example: "I've sent you my patch."
|
|
|
|
|
|
(Verb) The process of using a patch file to transform one
|
|
|
changeset into another.
|
|
|
|
|
|
Example: "You will need to patch that revision."
|
|
|
|
|
|
Pull
|
|
|
An operation in which changesets in a remote repository which are
|
|
|
not in the local repository are brought into the local
|
|
|
repository. Note that this operation without special arguments
|
|
|
only updates the repository, it does not update the files in the
|
|
|
working directory. See :hg:`help pull`.
|
|
|
|
|
|
Push
|
|
|
An operation in which changesets in a local repository which are
|
|
|
not in a remote repository are sent to the remote repository. Note
|
|
|
that this operation only adds changesets which have been committed
|
|
|
locally to the remote repository. Uncommitted changes are not
|
|
|
sent. See :hg:`help push`.
|
|
|
|
|
|
Repository
|
|
|
The metadata describing all recorded states of a collection of
|
|
|
files. Each recorded state is represented by a changeset. A
|
|
|
repository is usually (but not always) found in the ``.hg``
|
|
|
subdirectory of a working directory. Any recorded state can be
|
|
|
recreated by "updating" a working directory to a specific
|
|
|
changeset.
|
|
|
|
|
|
Repository head
|
|
|
See 'Head, repository'.
|
|
|
|
|
|
Revision
|
|
|
A state of the repository at some point in time. Earlier revisions
|
|
|
can be updated to by using :hg:`update`. See also 'Revision
|
|
|
number'; See also 'Changeset'.
|
|
|
|
|
|
Revision number
|
|
|
This integer uniquely identifies a changeset in a specific
|
|
|
repository. It represents the order in which changesets were added
|
|
|
to a repository, starting with revision number 0. Note that the
|
|
|
revision number may be different in each clone of a repository. To
|
|
|
identify changesets uniquely between different clones, see
|
|
|
'Changeset id'.
|
|
|
|
|
|
Revlog
|
|
|
History storage mechanism used by Mercurial. It is a form of delta
|
|
|
encoding, with occasional full revision of data followed by delta
|
|
|
of each successive revision. It includes data and an index
|
|
|
pointing to the data.
|
|
|
|
|
|
Rewriting history
|
|
|
See 'History, rewriting'.
|
|
|
|
|
|
Root
|
|
|
A changeset that has only the null changeset as its parent. Most
|
|
|
repositories have only a single root changeset.
|
|
|
|
|
|
Tip
|
|
|
The changeset with the highest revision number. It is the changeset
|
|
|
most recently added in a repository.
|
|
|
|
|
|
Tip, branch
|
|
|
The head of a given branch with the highest revision number. When
|
|
|
a branch name is used as a revision identifier, it refers to the
|
|
|
branch tip. See also 'Branch, head'. Note that because revision
|
|
|
numbers may be different in different repository clones, the
|
|
|
branch tip may be different in different cloned repositories.
|
|
|
|
|
|
Update
|
|
|
(Noun) Another synonym of changeset.
|
|
|
|
|
|
Example: "I've pushed an update".
|
|
|
|
|
|
(Verb) This term is usually used to describe updating the state of
|
|
|
the working directory to that of a specific changeset. See
|
|
|
:hg:`help update`.
|
|
|
|
|
|
Example: "You should update".
