For git in general, three rough rules are: + + - Most importantly, we never say "It's in POSIX; we'll happily + ignore your needs should your system not conform to it." + We live in the real world. + + - However, we often say "Let's stay away from that construct, + it's not even in POSIX". + + - In spite of the above two rules, we sometimes say "Although + this is not in POSIX, it (is so convenient | makes the code + much more readable | has other good characteristics) and + practically all the platforms we care about support it, so + let's use it". + + Again, we live in the real world, and it is sometimes a + judgement call, the decision based more on real world + constraints people face than what the paper standard says. + + +As for more concrete guidelines, just imitate the existing code +(this is a good guideline, no matter which project you are +contributing to). But if you must have a list of rules, +here they are. + +For shell scripts specifically (not exhaustive): + + - We prefer $( ... ) for command substitution; unlike ``, it + properly nests. It should have been the way Bourne spelled + it from day one, but unfortunately isn't. + + - We use ${parameter-word} and its [-=?+] siblings, and their + colon'ed "unset or null" form. + + - We use ${parameter#word} and its [#%] siblings, and their + doubled "longest matching" form. + + - We use Arithmetic Expansion $(( ... )). + + - No "Substring Expansion" ${parameter:offset:length}. + + - No shell arrays. + + - No strlen ${#parameter}. + + - No regexp ${parameter/pattern/string}. + + - We do not use Process Substitution <(list) or >(list). + + - We prefer "test" over "[ ... ]". + + - We do not write the noiseword "function" in front of shell + functions. + +For C programs: + + - We use tabs to indent, and interpret tabs as taking up to + 8 spaces. + + - We try to keep to at most 80 characters per line. + + - When declaring pointers, the star sides with the variable + name, i.e. "char *string", not "char* string" or + "char * string". This makes it easier to understand code + like "char *string, c;". + + - We avoid using braces unnecessarily. I.e. + + if (bla) { + x = 1; + } + + is frowned upon. A gray area is when the statement extends + over a few lines, and/or you have a lengthy comment atop of + it. Also, like in the Linux kernel, if there is a long list + of "else if" statements, it can make sense to add braces to + single line blocks. + + - Try to make your code understandable. You may put comments + in, but comments invariably tend to stale out when the code + they were describing changes. Often splitting a function + into two makes the intention of the code much clearer. + + - Double negation is often harder to understand than no negation + at all. + + - Some clever tricks, like using the !! operator with arithmetic + constructs, can be extremely confusing to others. Avoid them, + unless there is a compelling reason to use them. + + - Use the API. No, really. We have a strbuf (variable length + string), several arrays with the ALLOC_GROW() macro, a + path_list for sorted string lists, a hash map (mapping struct + objects) named "struct decorate", amongst other things. + + - When you come up with an API, document it. + + - The first #include in C files, except in platform specific + compat/ implementations, should be git-compat-util.h or another + header file that includes it, such as cache.h or builtin.h. + + - If you are planning a new command, consider writing it in shell + or perl first, so that changes in semantics can be easily + changed and discussed. Many git commands started out like + that, and a few are still scripts. + + - Avoid introducing a new dependency into git. This means you + usually should stay away from scripting languages not already + used in the git core command set (unless your command is clearly + separate from it, such as an importer to convert random-scm-X + repositories to git). diff --git a/Documentation/Makefile b/Documentation/Makefile index 39ec0ede02..43781fb248 100644 --- a/Documentation/Makefile +++ b/Documentation/Makefile @@ -2,10 +2,14 @@ MAN1_TXT= \ $(filter-out $(addsuffix .txt, $(ARTICLES) $(SP_ARTICLES)), \ $(wildcard git-*.txt)) \ gitk.txt -MAN5_TXT=gitattributes.txt gitignore.txt gitmodules.txt +MAN5_TXT=gitattributes.txt gitignore.txt gitcli.txt gitmodules.txt MAN7_TXT=git.txt -DOC_HTML=$(patsubst %.txt,%.html,$(MAN1_TXT) $(MAN5_TXT) $(MAN7_TXT)) +MAN_TXT = $(MAN1_TXT) $(MAN5_TXT) $(MAN7_TXT) +MAN_XML=$(patsubst %.txt,%.xml,$(MAN_TXT)) +MAN_HTML=$(patsubst %.txt,%.html,$(MAN_TXT)) + +DOC_HTML=$(MAN_HTML) ARTICLES = tutorial ARTICLES += tutorial-2 @@ -19,7 +23,10 @@ ARTICLES += everyday ARTICLES += git-tools ARTICLES += glossary # with their own formatting rules. -SP_ARTICLES = howto/revert-branch-rebase user-manual +SP_ARTICLES = howto/revert-branch-rebase howto/using-merge-subtree user-manual +API_DOCS = $(patsubst %.txt,%,$(filter-out technical/api-index-skel.txt technical/api-index.txt, $(wildcard technical/api-*.txt))) +SP_ARTICLES += $(API_DOCS) +SP_ARTICLES += technical/api-index DOC_HTML += $(patsubst %,%.html,$(ARTICLES) $(SP_ARTICLES)) @@ -29,6 +36,7 @@ DOC_MAN7=$(patsubst %.txt,%.7,$(MAN7_TXT)) prefix?=$(HOME) bindir?=$(prefix)/bin +htmldir?=$(prefix)/share/doc/git-doc mandir?=$(prefix)/share/man man1dir=$(mandir)/man1 man5dir=$(mandir)/man5 @@ -37,9 +45,7 @@ man7dir=$(mandir)/man7 ASCIIDOC=asciidoc ASCIIDOC_EXTRA = -ifdef ASCIIDOC8 -ASCIIDOC_EXTRA += -a asciidoc7compatible -endif +MANPAGE_XSL = callouts.xsl INSTALL?=install RM ?= rm -f DOC_REF = origin/man @@ -48,10 +54,21 @@ infodir?=$(prefix)/share/info MAKEINFO=makeinfo INSTALL_INFO=install-info DOCBOOK2X_TEXI=docbook2x-texi +ifndef PERL_PATH + PERL_PATH = /usr/bin/perl +endif -include ../config.mak.autogen -include ../config.mak +ifdef ASCIIDOC8 +ASCIIDOC_EXTRA += -a asciidoc7compatible +endif +ifdef DOCBOOK_XSL_172 +ASCIIDOC_EXTRA += -a docbook-xsl-172 +MANPAGE_XSL = manpage-1.72.xsl +endif + # # Please note that there is a minor bug in asciidoc. # The version after 6.0.3 _will_ include the patch found here: @@ -72,25 +89,29 @@ man1: $(DOC_MAN1) man5: $(DOC_MAN5) man7: $(DOC_MAN7) -info: git.info +info: git.info gitman.info install: man - $(INSTALL) -d -m755 $(DESTDIR)$(man1dir) - $(INSTALL) -d -m755 $(DESTDIR)$(man5dir) - $(INSTALL) -d -m755 $(DESTDIR)$(man7dir) - $(INSTALL) -m644 $(DOC_MAN1) $(DESTDIR)$(man1dir) - $(INSTALL) -m644 $(DOC_MAN5) $(DESTDIR)$(man5dir) - $(INSTALL) -m644 $(DOC_MAN7) $(DESTDIR)$(man7dir) + $(INSTALL) -d -m 755 $(DESTDIR)$(man1dir) + $(INSTALL) -d -m 755 $(DESTDIR)$(man5dir) + $(INSTALL) -d -m 755 $(DESTDIR)$(man7dir) + $(INSTALL) -m 644 $(DOC_MAN1) $(DESTDIR)$(man1dir) + $(INSTALL) -m 644 $(DOC_MAN5) $(DESTDIR)$(man5dir) + $(INSTALL) -m 644 $(DOC_MAN7) $(DESTDIR)$(man7dir) install-info: info - $(INSTALL) -d -m755 $(DESTDIR)$(infodir) - $(INSTALL) -m644 git.info $(DESTDIR)$(infodir) + $(INSTALL) -d -m 755 $(DESTDIR)$(infodir) + $(INSTALL) -m 644 git.info gitman.info $(DESTDIR)$(infodir) if test -r $(DESTDIR)$(infodir)/dir;

Use + dash-less forms (e.g. "git commit") instead. + + - Using dashed forms from your scripts, without first prepending the + return value from "git --exec-path" to the scripts' PATH, has been + informally deprecated since early 2006, but now it officially is. + + - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export + PATH" early in your script is not deprecated with this change. + + Users are strongly encouraged to adjust their habits and scripts now + to prepare for this change. + + * The post-receive hook was introduced in March 2007 to supersede + the post-update hook, primarily to overcome the command line length + limitation of the latter. Use of post-update hook will be deprecated + in future versions of git, starting from v1.6.0. + + * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found + option, and will be removed in the future. + + * "git peek-remote" is deprecated, as "git ls-remote" was written in C + and works for all transports; "git peek-remote" will be removed in + the future. + + * "git repo-config" which was an old name for "git config" command + has been supported without being advertised for a long time. The + next feature release will remove it. + + * From v1.6.0, the repack.usedeltabaseoffset config option will default + to true, which will give denser packfiles (i.e. more efficient storage). + The downside is that git older than version 1.4.4 will not be able + to directly use a repository packed using this setting. + + * From v1.6.0, the pack.indexversion config option will default to 2, + which is slightly more efficient, and makes repacking more immune to + data corruptions. Git older than version 1.5.2 may revert to version 1 + of the pack index with a manual "git index-pack" to be able to directly + access corresponding pack files. + + Updates since v1.5.3 -------------------- - * git-reset is now built-in. + * Comes with much improved gitk, with i18n. - * git-send-email can optionally talk over ssmtp and use SMTP-AUTH. + * Comes with git-gui 0.9.2 with i18n. - * git-rebase learned --whitespace option. + * gitk is now merged as a subdirectory of git.git project, in + preparation for its i18n. - * git-remote knows --mirror mode. + * progress displays from many commands are a lot nicer to the eye. + Transfer commands show throughput data. - * git-merge can call the "post-merge" hook. + * many commands that pay attention to per-directory .gitignore now do + so lazily, which makes the usual case go much faster. - * git-pack-objects can optionally run deltification with multiple threads. + * Output processing for '--pretty=format:<user format>' has been + optimized. - * git-archive can optionally substitute keywords in files marked with - export-subst attribute. + * Rename detection of diff family while detecting exact matches has + been greatly optimized. + + * Rename detection of diff family tries to make more natural looking + pairing. Earlier, if multiple identical rename sources were + found in the preimage, the source used was picked pretty much at random. + + * Value "true" for color.diff and color.status configuration used to + mean "always" (even when the output is not going to a terminal). + This has been corrected to mean the same thing as "auto". + + * "git diff" Porcelain now respects diff.external configuration, which + is another way to specify GIT_EXTERNAL_DIFF. + + * "git diff" can be told to use different prefixes other than + "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/". + + * "git diff" sometimes did not quote paths with funny + characters properly. + + * "git log" (and any revision traversal commands) misbehaved + when --diff-filter is given but was not asked to actually + produce diff. + + * HTTP proxy can be specified per remote repository using + remote.*.httpproxy configuration, or global http.proxy configuration + variable. * Various Perforce importer updates. + * Example update and post-receive hooks have been improved. + + * Any command that wants to take a commit object name can now use + ":/string" syntax to name a commit. + + * "git reset" is now built-in and its output can be squelched with -q. + + * "git reset --hard" does not make any sense in a bare + repository, but did not error out; fixed. + + * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH. + + * "git rebase" learned --whitespace option. + + * In "git rebase", when you decide not to replay a particular change + after the command stopped with a conflict, you can say "git rebase + --skip" without first running "git reset --hard", as the command now + runs it for you. + + * "git rebase --interactive" mode can now work on detached HEAD. + + * Other minor to serious bugs in "git rebase -i" have been fixed. + + * "git rebase" now detaches head during its operation, so after a + successful "git rebase" operation, the reflog entry branch@{1} for + the current branch points at the commit before the rebase was + started. + + * "git rebase -i" also triggers rerere to help your repeated merges. + + * "git merge" can call the "post-merge" hook. + + * "git pack-objects" can optionally run deltification with multiple + threads. + + * "git archive" can optionally substitute keywords in files marked with + export-subst attribute. + + * "git cherry-pick" made a misguided attempt to repeat the original + command line in the generated log message, when told to cherry-pick a + commit by naming a tag that points at it. It does not anymore. + + * "git for-each-ref" learned %(xxxdate:<date-format>) syntax to show the + various date fields in different formats. + + * "git gc --auto" is a low-impact way to automatically run a variant of + "git repack" that does not lose unreferenced objects (read: safer + than the usual one) after the user accumulates too many loose + objects. + + * "git clean" has been rewritten in C. + + * You need to explicitly set clean.requireForce to "false" to allow + "git clean" without -f to do any damage (lack of the configuration + variable used to mean "do not require -f option to lose untracked + files", but we now use the safer default). + + * The kinds of whitespace errors "git diff" and "git apply" notice (and + fix) can be controlled via 'core.whitespace' configuration variable + and 'whitespace' attribute in .gitattributes file. + + * "git push" learned --dry-run option to show what would happen if a + push is run. + + * "git push" does not update a tracking ref on the local side when the + remote refused to update the corresponding ref. + + * "git push" learned --mirror option. This is to push the local refs + one-to-one to the remote, and deletes refs from the remote that do + not exist anymore in the repository on the pushing side. + + * "git push" can remove a corrupt ref at the remote site with the usual + ":ref" refspec. + + * "git remote" knows --mirror mode. This is to set up configuration to + push into a remote repository to store local branch heads to the same + branch on the remote side, and remove branch heads locally removed + from local repository at the same time. Suitable for pushing into a + back-up repository. + + * "git remote" learned "rm" subcommand. + + * "git cvsserver" can be run via "git shell". Also, "cvs" is + recognized as a synonym for "git cvsserver", so that CVS users + can be switched to git just by changing their login shell. + + * "git cvsserver" acts more like receive-pack by running post-receive + and post-update hooks. + + * "git am" and "git rebase" are far less verbose. + + * "git pull" learned to pass --[no-]ff option to underlying "git + merge". + + * "git pull --rebase" is a different way to integrate what you fetched + into your current branch. + + * "git fast-export" produces data-stream that can be fed to fast-import + to reproduce the history recorded in a git repository. + + * "git add -i" takes pathspecs to limit the set of files to work on. + + * "git add -p" is a short-hand to go directly to the selective patch + subcommand in the interactive command loop and to exit when done. + + * "git add -i" UI has been colorized. The interactive prompt + and menu can be colored by setting color.interactive + configuration. The diff output (including the hunk picker) + are colored with color.diff configuration. + + * "git commit --allow-empty" allows you to create a single-parent + commit that records the same tree as its parent, overriding the usual + safety valve. + + * "git commit --amend" can amend a merge that does not change the tree + from its first parent. + + * "git commit" used to unconditionally strip comment lines that + began with '#' and removed excess blank lines. This behavior has + been made configurable. + + * "git commit" has been rewritten in C. + + * "git stash random-text" does not create a new stash anymore. It was + a UI mistake. Use "git stash save random-text", or "git stash" + (without extra args) for that. + + * "git stash clear extra-text" does not clear the whole stash + anymore. It is tempting to expect "git stash clear stash@{2}" + to drop only a single named stash entry, and it is rude to + discard everything when that is asked (but not provided). + + * "git prune --expire <time>" can exempt young loose objects from + getting pruned. + + * "git branch --contains <commit>" can list branches that are + descendants of a given commit. + + * "git log" learned --early-output option to help interactive GUI + implementations. + + * "git bisect" learned "skip" action to mark untestable commits. + + * "git bisect visualize" learned a shorter synonym "git bisect view". + + * "git bisect visualize" runs "git log" in a non-windowed + environments. It also can be told what command to run (e.g. "git + bisect visualize tig"). + + * "git format-patch" learned "format.numbered" configuration variable + to automatically turn --numbered option on when more than one commits + are formatted. + + * "git ls-files" learned "--exclude-standard" to use the canned set of + exclude files. + + * "git tag -a -f existing" begins the editor session using the existing + annotation message. + + * "git tag -m one -m bar" (multiple -m options) behaves similarly to + "git commit"; the parameters to -m options are formatted as separate + paragraphs. + + * The format "git show" outputs an annotated tag has been updated to + include "Tagger: " and "Date: " lines from the tag itself. Strictly + speaking this is a backward incompatible change, but this is a + reasonable usability fix and people's scripts shouldn't have been + relying on the exact output from "git show" Porcelain anyway. + + * "git cvsimport" did not notice errors from underlying "cvsps" + and produced a corrupt import silently. + + * "git cvsexportcommit" learned -w option to specify and switch to the + CVS working directory. + + * "git checkout" from a subdirectory learned to use "../path" to allow + checking out a path outside the current directory without cd'ing up. + + * "git checkout" from and to detached HEAD leaves a bit more + information in the reflog. + + * "git send-email --dry-run" shows full headers for easier diagnosis. + + * "git merge-ours" is now built-in. + + * "git svn" learned "info" and "show-externals" subcommands. + + * "git svn" run from a subdirectory failed to read settings from the + .git/config. + + * "git svn" learned --use-log-author option, which picks up more + descriptive name from From: and Signed-off-by: lines in the commit + message. + + * "git svn" wasted way too much disk to record revision mappings + between svn and git; a new representation that is much more compact + for this information has been introduced to correct this. + + * "git svn" left temporary index files it used without cleaning them + up; this was corrected. + + * "git status" from a subdirectory now shows relative paths, which + makes copy-and-pasting for git-checkout/git-add/git-rm easier. The + traditional behavior to show the full path relative to the top of + the work tree can be had by setting status.relativepaths + configuration variable to false. + + * "git blame" kept text for each annotated revision in core needlessly; + this has been corrected. + + * "git shortlog" learned to default to HEAD when the standard input is + a terminal and the user did not give any revision parameter. + + * "git shortlog" learned "-e" option to show e-mail addresses as well as + authors' names. + + * "git help" learned "-w" option to show documentation in browsers. + + * In addition there are quite a few internal clean-ups.

You can just pull from the +other project as long as there are no conflicting paths. + +The problematic case is when there are conflicting files. Potential +candidates are Makefiles and other standard filenames. You could merge +these files but probably you do not want to. A better solution for this +problem can be to merge the project as its own subdirectory. This is not +supported by the 'recursive' merge strategy, so just pulling won't work. + +What you want is the 'subtree' merge strategy, which helps you in such a +situation. + +In this example, let's say you have the repository at `/path/to/B` (but +it can be an URL as well, if you want). You want to merge the 'master' +branch of that repository to the `dir-B` subdirectory in your current +branch. + +Here is the command sequence you need: + +---------------- +$ git remote add -f Bproject /path/to/B <1> +$ git merge -s ours --no-commit Bproject/master <2> +$ git read-tree --prefix=dir-B/ -u Bproject/master <3> +$ git commit -m "Merge B project as our subdirectory" <4> + +$ git pull -s subtree Bproject master <5> +---------------- +<1> name the other project "Bproject", and fetch. +<2> prepare for the later step to record the result as a merge. +<3> read "master" branch of Bproject to the subdirectory "dir-B". +<4> record the merge result. +<5> maintain the result with subsequent merges using "subtree" + +The first four commands are used for the initial merge, while the last +one is to merge updates from 'B project'. + +Comparing 'subtree' merge with submodules +----------------------------------------- + +- The benefit of using subtree merge is that it requires less + administrative burden from the users of your repository. It works with + older (before Git v1.5.2) clients and you have the code right after + clone. + +- However if you use submodules then you can choose not to transfer the + submodule objects. This may be a problem with the subtree merge. + +- Also, in case you make changes to the other project, it is easier to + submit changes if you just use submodules. + +Additional tips +--------------- + +- If you made changes to the other project in your repository, they may + want to merge from your project. This is possible using subtree -- it + can shift up the paths in your tree and then they can merge only the + relevant parts of your tree. + +- Please note that if the other project merges from you, then it will + connects its history to yours, which can be something they don't want + to. diff --git a/Documentation/i18n.txt b/Documentation/i18n.txt index b95f99be6c..1e188e6e74 100644 --- a/Documentation/i18n.txt +++ b/Documentation/i18n.txt @@ -22,7 +22,7 @@ does not forbid it.
