* Wait for git diff to finish in git difftoolAlex Riesen2009-04-221-1/+2
| | | | | | | | | | In ActivetState Perl, exec does not wait for the started program. This breaks difftool tests and may cause unexpected behaviour: git difftool has returned, but the rest of code (diff and possibly the interactive program are still running in the background.

* difftool: add support for a difftool.prompt config variableDavid Aguilar2009-04-071-3/+12
| | | | | | | | | difftool now supports difftool.prompt so that users do not have to pass --no-prompt or hit enter each time a diff tool is launched. The --prompt flag overrides the configuration variable. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* difftool: move 'git-difftool' out of contribDavid Aguilar2009-04-071-0/+76
This prepares 'git-difftool' and its documentation for mainstream use. 'git-difftool-helper' became 'git-difftool--helper' since users should not use it directly. 'git-difftool' was added to the list of commands as an ancillaryinterrogator. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
