We will use the "simple" semantics that pushes the +current branch to the branch with the same name, only when the current +branch is set to integrate with that remote branch. There is a user +preference configuration variable "push.default" to change this, and +"git push" will warn about the upcoming change until you set this +variable in this release. + +"git branch --set-upstream" is deprecated and may be removed in a +relatively distant future. "git branch [-u|--set-upstream-to]" has +been introduced with a saner order of arguments to replace it. + + +Updates since v1.8.0 +-------------------- + +UI, Workflows & Features + + * Command-line completion scripts for tcsh and zsh have been added. + + * A new remote-helper interface for Mercurial has been added to + contrib/remote-helpers. + + * We used to have a workaround for a bug in ancient "less" that + causes it to exit without any output when the terminal is resized. + The bug has been fixed in "less" version 406 (June 2007), and the + workaround has been removed in this release. + + * Some documentation pages that used to ship only in the plain text + format are now formatted in HTML as well. + + * "git-prompt" scriptlet (in contrib/completion) can be told to paint + pieces of the hints in the prompt string in colors. + + * A new configuration variable "diff.context" can be used to + give the default number of context lines in the patch output, to + override the hardcoded default of 3 lines. + + * When "git checkout" checks out a branch, it tells the user how far + behind (or ahead) the new branch is relative to the remote tracking + branch it builds upon. The message now also advises how to sync + them up by pushing or pulling. This can be disabled with the + advice.statusHints configuration variable. + + * "git config --get" used to diagnose presence of multiple + definitions of the same variable in the same configuration file as + an error, but it now applies the "last one wins" rule used by the + internal configuration logic. Strictly speaking, this may be an + API regression but it is expected that nobody will notice it in + practice. + + * "git log -p -S<string>" now looks for the <string> after applying + the textconv filter (if defined); earlier it inspected the contents + of the blobs without filtering. + + * "git format-patch" learned the "--notes=<ref>" option to give + notes for the commit after the three-dash lines in its output. + + * "git log --grep=<pcre>" learned to honor the "grep.patterntype" + configuration set to "perl". + + * "git replace -d <object>" now interprets <object> as an extended + SHA-1 (e.g. HEAD~4 is allowed), instead of only accepting full hex + object name. + + * "git rm $submodule" used to punt on removing a submodule working + tree to avoid losing the repository embedded in it. Because + recent git uses a mechanism to separate the submodule repository + from the submodule working tree, "git rm" learned to detect this + case and removes the submodule working tree when it is safe to do so. + + * "git send-email" used to prompt for the sender address, even when + the committer identity is well specified (e.g. via user.name and + user.email configuration variables).

It should be read alongside api-builtin.txt. + +Runtime environment +------------------- + +git subcommands are standalone executables that live in the git exec +path, normally /usr/lib/git-core. The git executable itself is a +thin wrapper that knows where the subcommands live, and runs them by +passing command-line arguments to them. + +(If "git foo" is not found in the git exec path, the wrapper +will look in the rest of your $PATH for it. Thus, it's possible +to write local git extensions that don't live in system space.) + +Implementation languages +------------------------ + +Most subcommands are written in C or shell. A few are written in +Perl. + +While we strongly encourage coding in portable C for portability, +these specific scripting languages are also acceptable. We won't +accept more without a very strong technical case, as we don't want +to broaden the git suite's required dependencies. Import utilities, +surgical tools, remote helpers and other code at the edges of the +git suite are more lenient and we allow Python (and even Tcl/tk), +but they should not be used for core functions. + +This may change in the future. Especially Python is not allowed in +core because we need better Python integration in the git Windows +installer before we can be confident people in that environment +won't experience an unacceptably large loss of capability. + +C commands are normally written as single modules, named after the +command, that link a collection of functions called libgit. Thus, +your command 'git-foo' would normally be implemented as a single +"git-foo.c" (or "builtin/foo.c" if it is to be linked to the main +binary); this organization makes it easy for people reading the code +to find things. + +See the CodingGuidelines document for other guidance on what we consider +good practice in C and shell, and api-builtin.txt for the support +functions available to built-in commands written in C. + +What every extension command needs +---------------------------------- + +You must have a man page, written in asciidoc (this is what git help +followed by your subcommand name will display). Be aware that there is +a local asciidoc configuration and macros which you should use. It's +often helpful to start by cloning an existing page and replacing the +text content. + +You must have a test, written to report in TAP (Test Anything Protocol). +Tests are executables (usually shell scripts) that live in the 't' +subdirectory of the tree. Each test name begins with 't' and a sequence +number that controls where in the test sequence it will be executed; +conventionally the rest of the name stem is that of the command +being tested. + +Read the file t/README to learn more about the conventions to be used +in writing tests, and the test support library. + +Integrating a command +--------------------- + +Here are the things you need to do when you want to merge a new +subcommand into the git tree. + +1. Don't forget to sign off your patch! + +2. Append your command name to one of the variables BUILTIN_OBJS, +EXTRA_PROGRAMS, SCRIPT_SH, SCRIPT_PERL or SCRIPT_PYTHON. + +3. Drop its test in the t directory. + +4. If your command is implemented in an interpreted language with a +p-code intermediate form, make sure .gitignore in the main directory +includes a pattern entry that ignores such files. Python .pyc and +.pyo files will already be covered. + +5. If your command has any dependency on a particular version of +your language, document it in the INSTALL file. + +6. There is a file command-list.txt in the distribution main directory +that categorizes commands by type, so they can be listed in appropriate +subsections in the documentation's summary command list. Add an entry +for yours. To understand the categories, look at git-cmmands.txt +in the main directory. + +7.
