Git v1.8.5 Release Notes ======================== Backward compatibility notes (for Git 2.0) ------------------------------------------ When "git push [$there]" does not say what to push, we have used the traditional "matching" semantics so far (all your branches were sent to the remote as long as there already are branches of the same name over there). In Git 2.0, the default will change to the "simple" semantics that pushes: - only the current branch to the branch with the same name, and only when the current branch is set to integrate with that remote branch, if you are pushing to the same remote as you fetch from; or - only the current branch to the branch with the same name, if you are pushing to a remote that is not where you usually fetch from. Use the user preference configuration variable "push.default" to change this. If you are an old-timer who is used to the "matching" semantics, you can set the variable to "matching" to keep the traditional behaviour. If you want to live in the future early, you can set it to "simple" today without waiting for Git 2.0. When "git add -u" (and "git add -A") is run inside a subdirectory and does not specify which paths to add on the command line, it will operate on the entire tree in Git 2.0 for consistency with "git commit -a" and other commands. There will be no mechanism to make plain "git add -u" behave like "git add -u .". Current users of "git add -u" (without a pathspec) should start training their fingers to explicitly say "git add -u ." before Git 2.0 comes. A warning is issued when these commands are run without a pathspec and when you have local changes outside the current directory, because the behaviour in Git 2.0 will be different from today's version in such a situation. In Git 2.0, "git add " will behave as "git add -A ", so that "git add dir/" will notice paths you removed from the directory and record the removal. Versions before Git 2.0, including this release, will keep ignoring removals, but the users who rely on this behaviour are encouraged to start using "git add --ignore-removal " now before 2.0 is released. Updates since v1.8.4 -------------------- Foreign interfaces, subsystems and ports. * remote-hg remote helper misbehaved when interacting with a local Hg repository relative to the home directory, e.g. "clone hg::~/there". * imap-send ported to OS X uses Apple's security framework instead of OpenSSL one. * Subversion 1.8.0 that was recently released breaks older subversion clients coming over http/https in various ways. * "git fast-import" treats an empty path given to "ls" as the root of the tree. UI, Workflows & Features * "git check-ignore -z" applied the NUL termination to both its input (with --stdin) and its output, but "git check-attr -z" ignored the option on the output side. Make both honor -z on the input and output side the same way. * "git whatchanged" may still be used by old timers, but mention of it in documents meant for new users will only waste readers' time wonderig what the difference is between it and "git log". Make it less prominent in the general part of the documentation and explain that it is merely a "git log" with different default behaviour in its own document. Performance, Internal Implementation, etc. * Many commands use --dashed-option as a operation mode selector (e.g. "git tag --delete") that the user can use at most one (e.g. "git tag --delete --verify" is a nonsense) and you cannot negate (e.g. "git tag --no-delete" is a nonsense). parse-options API learned a new OPT_CMDMODE macro to make it easier to implement such a set of options. * OPT_BOOLEAN() in parse-options API was misdesigned to be "counting up" but many subcommands expect it to behave as "on/off". Update them to use OPT_BOOL() which is a proper boolean. * "git gc" exits early without doing a double-work when it detects that another instance of itself is already running. * Under memory pressure and/or file descriptor pressure, we used to close pack windows that are not used and also closed filehandle to an open but unused packfiles. These are now controlled separately to better cope with the load. Also contains various documentation updates and code clean-ups. Fixes since v1.8.4 ------------------ Unless otherwise noted, all the fixes since v1.8.4 in the maintenance track are contained in this release (see release notes to them for details). * Setting submodule.*.path configuration variable to true (without giving "= value") caused Git to segfault. (merge 4b05440 jl/some-submodule-config-are-not-boolean later to maint). * "git rebase -i" (there could be others, as the root cause is pretty generic) fed a random, data dependeant string to 'echo' and expects it to come out literally, corrupting its error message. (merge 89b0230 mm/no-shell-escape-in-die-message later to maint). * Some people still use rather old versions of bash, which cannot grok some constructs like 'printf -v varname' the prompt and completion code started to use recently. (merge a44aa69 bc/completion-for-bash-3.0 later to maint). * Code to read configuration from a blob object did not compile on platforms with fgetc() etc. implemented as macros. (merge 49d6cfa hv/config-from-blob later to maint-1.8.3). * The recent "short-cut clone connectivity check" topic broke a shallow repository when a fetch operation tries to auto-follow tags. (merge 6da8bdc nd/fetch-pack-shallow-fix later to maint-1.8.3).
