Add the option "--ignore-submodules" to "git status" In some use cases it is not desirable that "git status" considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree (this was the behavior before 1.7.0). An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved when using the "dirty" parameter. And if you want to ignore any changes to submodules, you can now do that by using this option without parameters or with "all" (when the config option status.submodulesummary is set, using "all" will also suppress the output of the submodule summary). A new function handle_ignore_submodules_arg() is introduced to parse this option new to "git status" in a single location, as "git diff" already knew it.

color: delay auto-color decision until point of use When we read a color value either from a config file or from the command line, we use git_config_colorbool to convert it from the tristate always/never/auto into a single yes/no boolean value. This has some timing implications with respect to starting a pager. If we start (or decide not to start) the pager before checking the colorbool, everything is fine. Either isatty(1) will give us the right information, or we will properly check for pager_in_use(). However, if we decide to start a pager after we have checked the colorbool, things are not so simple. If stdout is a tty, then we will have already decided to use color. However, the user may also have configured color.pager not to use color with the pager. In this case, we need to actually turn off color. Unfortunately, the pager code has no idea which color variables were turned on (and there are many of them throughout the code, and they may even have been manipulated after the colorbool selection by something like "--color" on the command line). This bug can be seen any time a pager is started after config and command line options are checked. This has affected "git diff" since 89d07f7 (diff: don't run pager if user asked for a diff style exit code, 2007-08-12). It has also affect the log family since 1fda91b (Fix 'git log' early pager startup error case, 2010-08-24). This patch splits the notion of parsing a colorbool and actually checking the configuration. The "use_color" variables now have an additional possible value, GIT_COLOR_AUTO. Users of the variable should use the new "want_color()" wrapper, which will lazily determine and cache the auto-color decision.

The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

Submodules: Add the new "ignore" config option for diff and status The new "ignore" config option controls the default behavior for "git status" and the diff family. It specifies under what circumstances they consider submodules as modified and can be set separately for each submodule. The command line option "--ignore-submodules=" has been extended to accept the new parameter "none" for both status and diff. Users that chose submodules to get rid of long work tree scanning times might want to set the "dirty" option for those submodules. This brings back the pre 1.7.0 behavior, where submodule work trees were never scanned for modifications. By using "--ignore-submodules=none" on the command line the status and diff commands can be told to do a full scan. This option can be set to the following values (which have the same name and meaning as for the "--ignore-submodules" option of status and diff): "all": All changes to the submodule will be ignored. "dirty": Only differences of the commit recorded in the superproject and the submodules HEAD will be considered modifications, all changes to the work tree of the submodule will be ignored. When using this value, the submodule will not be scanned for work tree changes at all, leading to a performance benefit on large submodules. "untracked": Only untracked files in the submodules work tree are ignored, a changed HEAD and/or modified files in the submodule will mark it as modified. "none" (which is the default): Either untracked or modified files in a submodules work tree or a difference between the subdmodules HEAD and the commit recorded in the superproject will make it show up as changed. This value is added as a new parameter for the "--ignore-submodules" option of the diff family and "git status" so the user can override the settings in the configuration.

status/commit: show staged submodules regardless of ignore config Currently setting submodule.<name>.ignore and/or diff.ignoreSubmodules to "all" suppresses all output of submodule changes for the diff family, status and commit. For status and commit this is really confusing, as it even when the user chooses to record a new commit for an ignored submodule by adding it manually this change won't show up under the to-be-committed changes. To add insult to injury, a later "git commit" will error out with "nothing to commit" when only ignored submodules are staged. Fix that by making wt_status always print staged submodule changes, no matter what ignore settings are configured. The only exception is when the user explicitly uses the "--ignore-submodules=all" command line option, in that case the submodule output is still suppressed. This also makes "git commit" work again when only modifications of ignored submodules are staged, as that command uses the "commitable" member of the wt_status struct to determine if staged changes are present. But this only happens when the commit command uses the wt_status* functions to produce status output for human consumption (when forking an editor or with --dry-run), in all other cases (e.g. when run in a script with '-m') another code path is taken which uses index_differs_from() to determine if any changes are staged which still ignores submodules according to their configuration. This will be fixed in a follow-up commit. Change t7508 to reflect this new behavior and add three new tests to show that a single staged submodule configured to be ignored will be committed when the status output is generated and won't be if not. Also update the documentation of the ignore config options accordingly. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

status: add option to show ignored files differently Teach the status command more flexibility in how ignored files are reported. Currently, the reporting of ignored files and untracked files are linked. You cannot control how ignored files are reported independently of how untracked files are reported (i.e. `all` vs `normal`). This makes it impossible to show untracked files with the `all` option, but show ignored files with the `normal` option. This work 1) adds the ability to control the reporting of ignored files independently of untracked files and 2) introduces the concept of status reporting ignored paths that explicitly match an ignored pattern. There are 2 benefits to these changes: 1) if a consumer needs all untracked files but not all ignored files, there is a performance benefit to not scanning all contents of an ignored directory and 2) returning ignored files that explicitly match a path allow a consumer to make more informed decisions about when a status result might be stale. This commit implements --ignored=matching with --untracked-files=all. The following commit will implement --ignored=matching with --untracked=files=normal. As an example of where this flexibility could be useful is that our application (Visual Studio) runs the status command and presents the output. It shows all untracked files individually (e.g. using the '--untracked-files==all' option), and would like to know about which paths are ignored. It uses information about ignored paths to make decisions about when the status result might have changed. Additionally, many projects place build output into directories inside a repository's working directory (e.g. in "bin/" and "obj/" directories). Normal usage is to explicitly ignore these 2 directory names in the .gitignore file (rather than or in addition to the *.obj pattern).If an application could know that these directories are explicitly ignored, it could infer that all contents are ignored as well and make better informed decisions about files in these directories. It could infer that any changes under these paths would not affect the output of status. Additionally, there can be a significant performance benefit by avoiding scanning through ignored directories. When status is set to report matching ignored files, it has the following behavior. Ignored files and directories that explicitly match an exclude pattern are reported. If an ignored directory matches an exclude pattern, then the path of the directory is returned. If a directory does not match an exclude pattern, but all of its contents are ignored, then the contained files are reported instead of the directory.

interpret-trailers: honor the cut line If a commit message is edited with the "verbose" option, the buffer will have a cut line and diff after the log message, like so: my subject # ------------------------ >8 ------------------------ # Do not touch the line above. # Everything below will be removed. diff --git a/foo.txt b/foo.txt index 5716ca5..7601807 100644 --- a/foo.txt +++ b/foo.txt @@ -1 +1 @@ -bar +baz "git interpret-trailers" is unaware of the cut line, and assumes the trailer block would be at the end of the whole thing. This can easily be seen with: $ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \ git commit --amend -v Teach "git interpret-trailers" to notice the cut-line and ignore the remainder of the input when looking for a place to add new trailer block.

Because the function ignore_non_trailer() used by the command takes a <pointer, length> pair, not a strbuf, steal the logic from wt_status_truncate_message_at_cut_line() to create a new wt_status_locate_end() helper function that takes <pointer, length> pair, and make ignore_non_trailer() call it to help "interpret-trailers". Since there is only one caller of wt_status_truncate_message_at_cut_line() in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead and remove the old helper that no longer has any caller.

Add the option "--ignore-submodules" to "git status" In some use cases it is not desirable that "git status" considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree (this was the behavior before 1.7.0). An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved when using the "dirty" parameter. And if you want to ignore any changes to submodules, you can now do that by using this option without parameters or with "all" (when the config option status.submodulesummary is set, using "all" will also suppress the output of the submodule summary). A new function handle_ignore_submodules_arg() is introduced to parse this option new to "git status" in a single location, as "git diff" already knew it.

status: add option to show ignored files differently Teach the status command more flexibility in how ignored files are reported. Currently, the reporting of ignored files and untracked files are linked. You cannot control how ignored files are reported independently of how untracked files are reported (i.e. `all` vs `normal`). This makes it impossible to show untracked files with the `all` option, but show ignored files with the `normal` option. This work 1) adds the ability to control the reporting of ignored files independently of untracked files and 2) introduces the concept of status reporting ignored paths that explicitly match an ignored pattern. There are 2 benefits to these changes: 1) if a consumer needs all untracked files but not all ignored files, there is a performance benefit to not scanning all contents of an ignored directory and 2) returning ignored files that explicitly match a path allow a consumer to make more informed decisions about when a status result might be stale. This commit implements --ignored=matching with --untracked-files=all. The following commit will implement --ignored=matching with --untracked=files=normal. As an example of where this flexibility could be useful is that our application (Visual Studio) runs the status command and presents the output. It shows all untracked files individually (e.g. using the '--untracked-files==all' option), and would like to know about which paths are ignored. It uses information about ignored paths to make decisions about when the status result might have changed. Additionally, many projects place build output into directories inside a repository's working directory (e.g. in "bin/" and "obj/" directories). Normal usage is to explicitly ignore these 2 directory names in the .gitignore file (rather than or in addition to the *.obj pattern).If an application could know that these directories are explicitly ignored, it could infer that all contents are ignored as well and make better informed decisions about files in these directories. It could infer that any changes under these paths would not affect the output of status. Additionally, there can be a significant performance benefit by avoiding scanning through ignored directories. When status is set to report matching ignored files, it has the following behavior. Ignored files and directories that explicitly match an exclude pattern are reported. If an ignored directory matches an exclude pattern, then the path of the directory is returned. If a directory does not match an exclude pattern, but all of its contents are ignored, then the contained files are reported instead of the directory.

wt-status: actually ignore submodules when requested Since ff6f1f564 (submodule-config: lazy-load a repository's .gitmodules file, 2017-08-03) rebase interactive fails if there are any submodules with unstaged changes which have been configured with a value for 'submodule.<name>.ignore' in the repository's config. This is due to how configured values of 'submodule.<name>.ignore' are handled in addition to a change in how the submodule config is loaded. When the diff machinery hits a submodule (gitlink as well as a corresponding entry in the submodule subsystem) it will read the value of 'submodule.<name>.ignore' stored in the repository's config and if the config is present it will clear the 'IGNORE_SUBMODULES' (which is the flag explicitly requested by rebase interactive), 'IGNORE_UNTRACKED_IN_SUBMODULES', and 'IGNORE_DIRTY_SUBMODULES' diff flags and then set one of them based on the configured value. Historically this wasn't a problem because the submodule subsystem wasn't initialized because the .gitmodules file wasn't explicitly loaded by the rebase interactive command. So when the diff machinery hit a submodule it would skip over reading any configured values of 'submodule.<name>.ignore'. In order to preserve the behavior of submodules being ignored by rebase interactive, also set the 'OVERRIDE_SUBMODULE_CONFIG' diff flag when submodules are requested to be ignored when checking for unstaged changes.

Fixing this raises a question of fault: should run_diff_index() handle this case, or is the caller wrong to pass an empty pending list? Looking at the other callers of run_diff_index(), they handle this in one of three ways: - they resolve the object themselves, and avoid doing the diff if it's not valid - they resolve the object themselves, and fall back to the empty tree - they use setup_revisions(), which will die() if the object isn't valid Since this is the only broken caller, that argues that the fix should go there. Falling back to the empty tree makes sense here, as we'd claim uncommitted changes if and only if the index is non-empty. This may be a little funny in the case of corruption (the corrupt HEAD probably _isn't_ empty), but: - we don't actually know the reason here that HEAD didn't resolve (the much more likely case is that we have an unborn HEAD, in which case the empty tree comparison is the right thing) - this matches how other code, like "git diff", behaves While we're thinking about it, let's add an assertion to run_diff_index(). It should always be passed a single object, and as this bug shows, it's easy to get it wrong (and an assertion is easier to hunt down than a segfault, or a quietly ignored extra tree).
