GIT v1.5.3.3 Release Notes
|
||||
==========================
|
||||
|
||||
Fixes since v1.5.3.2
|
||||
--------------------
|
||||
|
||||
* git-quiltimport did not like it when a patch described in the
|
||||
series file does not exist.
|
||||
|
||||
* p4 importer missed executable bit in some cases.
|
||||
|
||||
* The default shell on some FreeBSD did not execute the
|
||||
argument parsing code correctly and made git unusable.
|
||||
|
||||
* git-svn incorrectly spawned pager even when the user user
|
||||
explicitly asked not to.
|
||||
|
||||
* sample post-receive hook overquoted the envelope sender
|
||||
value.
|
||||
|
||||
* git-am got confused when the patch contained a change that is
|
||||
only about type and not contents.
|
||||
|
||||
* git-mergetool did not show our and their version of the
|
||||
conflicted file when started from a subdirectory of the
|
||||
project.
|
||||
|
||||
* git-mergetool did not pass correct options when invoking diff3.
|
||||
|
||||
* git-log sometimes invoked underlying "diff" machinery
|
||||
unnecessarily.

Submodules
|
||||
==========
|
||||
|
||||
This tutorial explains how to create and publish a repository with submodules
|
||||
using the gitlink:git-submodule[1] command.
|
||||
Large projects are often composed of smaller, self-contained modules. For
|
||||
example, an embedded Linux distribution's source tree would include every
|
||||
piece of software in the distribution with some local modifications; a movie
|
||||
player might need to build against a specific, known-working version of a
|
||||
decompression library; several independent programs might all share the same
|
||||
build scripts.
|
||||
|
||||
Submodules maintain their own identity; the submodule support just stores the
|
||||
submodule repository location and commit ID, so other developers who clone the
|
||||
superproject can easily clone all the submodules at the same revision.
|
||||
With centralized revision control systems this is often accomplished by
|
||||
including every module in one single repository. Developers can check out
|
||||
all modules or only the modules they need to work with. They can even modify
|
||||
files across several modules in a single commit while moving things around
|
||||
or updating APIs and translations.
|
||||
|
||||
Git does not allow partial checkouts, so duplicating this approach in Git
|
||||
would force developers to keep a local copy of modules they are not
|
||||
interested in touching. Commits in an enormous checkout would be slower
|
||||
than you'd expect as Git would have to scan every directory for changes.
|
||||
If modules have a lot of local history, clones would take forever.
|
||||
|
||||
On the plus side, distributed revision control systems can much better
|
||||
integrate with external sources. In a centralized model, a single arbitrary
|
||||
snapshot of the external project is exported from its own revision control
|
||||
and then imported into the local revision control on a vendor branch. All
|
||||
the history is hidden. With distributed revision control you can clone the
|
||||
entire external history and much more easily follow development and re-merge
|
||||
local changes.
|
||||
|
||||
Git's submodule support allows a repository to contain, as a subdirectory, a
|
||||
checkout of an external project. Submodules maintain their own identity;
|
||||
the submodule support just stores the submodule repository location and
|
||||
commit ID, so other developers who clone the containing project
|
||||
("superproject") can easily clone all the submodules at the same revision.
|
||||
Partial checkouts of the superproject are possible: you can tell Git to
|
||||
clone none, some or all of the submodules.
|
||||
|
||||
The gitlink:git-submodule[1] command is available since Git 1.5.3. Users
|
||||
with Git 1.5.2 can look up the submodule commits in the repository and
|
||||
manually check them out; earlier versions won't recognize the submodules at
|
||||
all.
|
||||
|
||||
To see how submodule support works, create (for example) four example
|
||||
repositories that can be used later as a submodule:
