If you prefer a quicker check only on loose + objects (the old default), you can say "git fsck --no-full". This + has been supported by 1.5.4 and newer versions of git, so it is + safe to write it in your script even if you use slightly older git + on some of your machines. + +Preparing yourselves for compatibility issues in 1.7.0 +------------------------------------------------------ + +In git 1.7.0, which is planned to be the release after 1.6.6, there will +be a handful of behaviour changes that will break backward compatibility. + +These changes were discussed long time ago and existing behaviours have +been identified as more problematic to the userbase than keeping them for +the sake of backward compatibility. + +When necessary, a transition strategy for existing users has been designed +not to force them running around setting configuration variables and +updating their scripts in order to either keep the traditional behaviour +or adjust to the new behaviour, on the day their sysadmin decides to install +the new version of git. When we switched from "git-foo" to "git foo" in +1.6.0, even though the change had been advertised and the transition +guide had been provided for a very long time, the users procrastinated +during the entire transition period, and ended up panicking on the day +their sysadmins updated their git installation. We are trying to avoid +repeating that unpleasantness in the 1.7.0 release. + +For changes decided to be in 1.7.0, commands that will be affected +have been much louder to strongly discourage such procrastination, and +they continue to be in this release. If you have been using recent +versions of git, you would have seen warnings issued when you used +features whose behaviour will change, with a clear instruction on how +to keep the existing behaviour if you want to. You hopefully are +already well prepared. + +Of course, we have also been giving "this and that will change in +1.7.0; prepare yourselves" warnings in the release notes and +announcement messages for the past few releases. Let's see how well +users will fare this time. + + * "git push" into a branch that is currently checked out (i.e. pointed by + HEAD in a repository that is not bare) will be refused by default. + + Similarly, "git push $there :$killed" to delete the branch $killed + in a remote repository $there, when $killed branch is the current + branch pointed at by its HEAD, will be refused by default. + + Setting the configuration variables receive.denyCurrentBranch and + receive.denyDeleteCurrent to 'ignore' in the receiving repository + can be used to override these safety features. Versions of git + since 1.6.2 have issued a loud warning when you tried to do these + operations without setting the configuration, so repositories of + people who still need to be able to perform such a push should + already have been future proofed. + + Please refer to: + + http://git.or.cz/gitwiki/GitFaq#non-bare + http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007 + + for more details on the reason why this change is needed and the + transition process that already took place so far. + + * "git send-email" will not make deep threads by default when sending a + patch series with more than two messages. All messages will be sent + as a reply to the first message, i.e. cover letter. Git 1.6.6 (this + release) will issue a warning about the upcoming default change, when + it uses the traditional "deep threading" behaviour as the built-in + default. To squelch the warning but still use the "deep threading" + behaviour, give --chain-reply-to option or set sendemail.chainreplyto + to true. + + It has been possible to configure send-email to send "shallow thread" + by setting sendemail.chainreplyto configuration variable to false. + The only thing 1.7.0 release will do is to change the default when + you haven't configured that variable. + + * "git status" will not be "git commit --dry-run". This change does not + affect you if you run the command without pathspec. + + Nobody sane found the current behaviour of "git status Makefile" useful + nor meaningful, and it confused users. "git commit --dry-run" has been + provided as a way to get the current behaviour of this command since + 1.6.5. + + * "git diff" traditionally treated various "ignore whitespace" options + only as a way to filter the patch output. "git diff --exit-code -b" + exited with non-zero status even if all changes were about changing the + amount of whitespace and nothing else. and "git diff -b" showed the + "diff --git" header line for such a change without patch text. + + In 1.7.0, the "ignore whitespaces" will affect the semantics of the + diff operation itself. A change that does not affect anything but + whitespaces will be reported with zero exit status when run with + --exit-code, and there will not be "diff --git" header for such a + change. + + +Updates since v1.6.5 +-------------------- + +(subsystems) + + * various gitk updates including use of themed widgets under Tk 8.5, + Japanese translation, a fix to a bug when running "gui blame" from + a subdirectory, etc. + + * various git-gui updates including new translations, wm states fixes, + Tk bug workaround after quitting, improved heuristics to trigger gc, + etc. + + * various git-svn updates. + + * "git fetch" over http learned a new mode that is different from the + traditional "dumb commit walker". + +(portability) + + * imap-send can be built on mingw port. + +(performance) + + * "git diff -B" has smaller memory footprint. + +(usability, bells and whistles) + + * The object replace mechanism can be bypassed with --no-replace-objects + global option given to the "git" program. + + * In configuration files, a few variables that name paths can begin with ~/ + and ~username/ and they are expanded as expected. + + * "git subcmd -h" now shows short usage help for many more subcommands. + + * "git bisect reset" can reset to an arbitrary commit. + + * "git checkout frotz" when there is no local branch "frotz" but there + is only one remote tracking branch "frotz" is taken as a request to + start the named branch at the corresponding remote tracking branch. + + * "git commit -c/-C/--amend" can be told with a new "--reset-author" option + to ignore authorship information in the commit it is taking the message + from. + + * "git describe" can be told to add "-dirty" suffix with "--dirty" option. + + * "git diff" learned --submodule option to show a list of one-line logs + instead of differences between the commit object names. + + * "git diff" learned to honor diff.color.func configuration to paint + function name hint printed on the hunk header "@@ -j,k +l,m @@" line + in the specified color. + + * "git fetch" learned --all and --multiple options, to run fetch from + many repositories, and --prune option to remove remote tracking + branches that went stale. These make "git remote update" and "git + remote prune" less necessary (there is no plan to remove "remote + update" nor "remote prune", though). + + * "git fsck" by default checks the packfiles (i.e. "--full" is the + default); you can turn it off with "git fsck --no-full". + + * "git grep" can use -F (fixed strings) and -i (ignore case) together. + + * import-tars contributed fast-import frontend learned more types of + compressed tarballs. + + * "git instaweb" knows how to talk with mod_cgid to apache2. + + * "git log --decorate" shows the location of HEAD as well. + + * "git log" and "git rev-list" learned to take revs and pathspecs from + the standard input with the new "--stdin" option. + + * "--pretty=format" option to "log" family of commands learned: + + . to wrap text with the "%w()" specifier. + . to show reflog information with "%g[sdD]" specifier. + + * "git notes" command to annotate existing commits. + + * "git merge" (and "git pull") learned --ff-only option to make it fail + if the merge does not result in a fast-forward. + + * "git mergetool" learned to use p4merge. + + * "git rebase -i" learned "reword" that acts like "edit" but immediately + starts an editor to tweak the log message without returning control to + the shell, which is done by "edit" to give an opportunity to tweak the + contents. + + * "git send-email" can be told with "--envelope-sender=auto" to use the + same address as "From:" address as the envelope sender address. + + * "git send-email" will issue a warning when it defaults to the + --chain-reply-to behaviour without being told by the user and + instructs to prepare for the change of the default in 1.7.0 release. + + * In "git submodule add <repository> <path>", <path> is now optional and + inferred from <repository> the same way "git clone <repository>" does. + + * "git svn" learned to read SVN 1.5+ and SVK merge tickets. + + * "git svn" learned to recreate empty directories tracked only by SVN. + + * "gitweb" can optionally render its "blame" output incrementally (this + requires JavaScript on the client side). + + * Author names shown in gitweb output are links to search commits by the + author. + +Fixes since v1.6.5 +------------------ + +All of the fixes in v1.6.5.X maintenance series are included in this +release, unless otherwise noted. |
