2017-03-15update submodules: add a config option to determine if submodules are updatedLibravatar Stefan Beller2-0/+7
In later patches we introduce the options and flag for commands that modify the working directory, e.g. git-checkout. Have a central place to store such settings whether we want to update a submodule. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-15update submodules: add submodule config parsingLibravatar Stefan Beller2-8/+29
Similar to b33a15b08 (push: add recurseSubmodules config option, 2015-11-17) and 027771fcb1 (submodule: allow erroneous values for the fetchRecurseSubmodules option, 2015-08-17), we add submodule-config code that is later used to parse whether we are interested in updating submodules. We need the `die_on_error` parameter to be able to call this parsing function for the config file as well, which if incorrect lets Git die. As we're just touching the header file, also mark all functions extern. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-03-15lib-submodule-update.sh: define tests for recursing into submodulesLibravatar Stefan Beller1-2/+504
Currently lib-submodule-update.sh provides 2 functions test_submodule_switch and test_submodule_forced_switch that are used by a variety of tests to ensure that submodules behave as expected. The current expected behavior is that submodules are not touched at all (see 42639d2317a for the exact setup). In the future we want to teach all these commands to recurse into submodules. To do that, we'll add two testing functions to submodule-update-lib.sh: test_submodule_switch_recursing and test_submodule_forced_switch_recursing. These two functions behave in analogy to the already existing functions just with a different expectation on submodule behavior. The submodule in the working tree is expected to be updated to the recorded submodule version. The behavior is analogous to e.g. the behavior of files in a nested directory in the working tree, where a change to the working tree handles any arising directory/file conflicts just fine.

2017-03-15lib-submodule-update.sh: do not use ./. as submodule remoteLibravatar Stefan Beller1-2/+13
Adding the repository itself as a submodule does not make sense in the real world. In our test suite we used to do that out of convenience in some tests as the current repository has easiest access for setting up 'just a submodule'. However this doesn't quite test the real world, so let's do not follow this pattern any further and actually create an independent repository that we can use as a submodule. When using './.' as the remote the superproject and submodule share the same objects, such that testing if a given sha1 is a valid commit works in either repository. As running commands in an unpopulated submodule fall back to the superproject, this happens in `reset_work_tree_to` to determine if we need to populate the submodule. Fix this bug by checking in the actual remote now. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-03-15connect_work_tree_and_git_dir: safely create leading directoriesLibravatar Stefan Beller2-20/+23
In a later patch we'll use connect_work_tree_and_git_dir when the directory for the gitlink file doesn't exist yet. This patch makes connect_work_tree_and_git_dir safe to use for both cases of either the git dir or the working dir missing. To do so, we need to call safe_create_leading_directories[_const] on both directories. However this has to happen before we construct the absolute paths as real_pathdup assumes the directories to be there already. So for both the config file in the git dir as well as the .git link file we need to a) construct the name b) call SCLD c) get the absolute path d) once a-c is done for both we can consume the absolute path to compute the relative path to each other and store those relative paths. The implementation provided here puts a) and b) for both cases first, and then performs c and d after. One of the two users of 'connect_work_tree_and_git_dir' already checked for the directory being there, so we can loose that check as connect_work_tree_and_git_dir handles this functionality now.

Don't mention git reset --hard in the documentation for git stash save. It's an implementation detail that doesn't matter to the end user and thus shouldn't be exposed to them.

2017-02-13docs/git-submodule: fix unbalanced quoteLibravatar Jeff King1-3/+6
The documentation gives an example of the submodule foreach command that uses both backticks and single-quotes. We stick the whole thing inside "+" markers to make it monospace, but the inside punctuation still needs escaping. We handle the backticks with "{backtick}", and use backslash-escaping for the single-quotes. But we missed the escaping on the second quote. Fortunately, asciidoc renders this unbalanced quote as we want (showing the quote), but asciidoctor does not. We could fix it by adding the missing backslash. However, let's take a step back. Even when rendered correctly, it's hard to read a long command stuck into the middle of a paragraph, and the important punctuation is hard to notice. Let's instead bump it into its own single-line code block. That makes both the source and the rendered result more readable, and as a bonus we don't have to worry about quoting at all.

2017-02-08push options: pass push options to the transport helperLibravatar Stefan Beller3-0/+26
When using non-builtin protocols relying on a transport helper (such as http), push options are not propagated to the helper. The user could ask for push options and a push would seemingly succeed, but the push options would never be transported to the server, misleading the users expectation. Fix this by propagating the push options to the transport helper. This is only addressing the first issue of (1) the helper protocol does not propagate push-option (2) the http helper is not prepared to handle push-option Once we fix (2), the http transport helper can make use of push options as well, but that happens as a follow up. (1) is a bug fix, whereas (2) is a feature, which is why we only do (1) here. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-08diff: print line prefix for --name-only outputLibravatar Jeff King2-0/+49
If you run "git log --graph --name-only", the pathnames are not indented to go along with their matching commits (unlike all of the other diff formats). We need to output the line prefix for each item before writing it. The tests cover both --name-status and --name-only. The former actually gets this right already, because it builds on the --raw format functions. It's only --name-only which uses its own code (and this fix mirrors the code in diff_flush_raw()). Note that the tests don't follow our usual style of setting up the "expect" output inside the test block. This matches the surrounding style, but more importantly it is easier to read: we don't have to worry about embedded single-quotes, and the leading indentation is more obvious.
