Check `cache.h` - this variable is +used to track the allocated size of the list. + +Per entry, we find: + +`item` is the object provided upon which to base the object walk. Items in Git +can be blobs, trees, commits, or tags. (See `Documentation/gittutorial-2.txt`.) + +`name` is the object ID (OID) of the object - a hex string you may be familiar +with from using Git to organize your source in the past. Check the tutorial +mentioned above towards the top for a discussion of where the OID can come +from. + +`whence` indicates some information about what to do with the parents of the +specified object. We'll explore this flag more later on; take a look at +`Documentation/revisions.txt` to get an idea of what could set the `whence` +value. + +`flags` are used to hint the beginning of the revision walk and are the first +block under the `#include`s in `revision.h`. The most likely ones to be set in +the `rev_cmdline_info` are `UNINTERESTING` and `BOTTOM`, but these same flags +can be used during the walk, as well. + +=== `struct rev_info` + +This one is quite a bit longer, and many fields are only used during the walk +by `revision.c` - not configuration options. Most of the configurable flags in +`struct rev_info` have a mirror in `Documentation/rev-list-options.txt`. It's a +good idea to take some time and read through that document. + +== Basic Commit Walk + +First, let's see if we can replicate the output of `git log --oneline`. We'll +refer back to the implementation frequently to discover norms when performing +an object walk of our own. + +To do so, we'll first find all the commits, in order, which preceded the current +commit. We'll extract the name and subject of the commit from each. + +Ideally, we will also be able to find out which ones are currently at the tip of +various branches. + +=== Setting Up + +Preparing for your object walk has some distinct stages. + +1. Perform default setup for this mode, and others which may be invoked. +2. Check configuration files for relevant settings. +3. Set up the `rev_info` struct. +4. Tweak the initialized `rev_info` to suit the current walk. +5. Prepare the `rev_info` for the walk. +6. Iterate over the objects, processing each one. + +==== Default Setups + +Before examining configuration files which may modify command behavior, set up +default state for switches or options your command may have. If your command +utilizes other Git components, ask them to set up their default states as well. +For instance, `git log` takes advantage of `grep` and `diff` functionality, so +its `init_log_defaults()` sets its own state (`decoration_style`) and asks +`grep` and `diff` to initialize themselves by calling each of their +initialization functions. + +For our first example within `git walken`, we don't intend to use any other +components within Git, and we don't have any configuration to do. However, we +may want to add some later, so for now, we can add an empty placeholder. Create +a new function in `builtin/walken.c`: + +---- +static void init_walken_defaults(void) +{ + /* + * We don't actually need the same components `git log` does; leave this + * empty for now. + */ +} +---- + +Make sure to add a line invoking it inside of `cmd_walken()`. + +---- +int cmd_walken(int argc, const char **argv, const char *prefix) +{ + init_walken_defaults(); +} +---- + +==== Configuring From `.gitconfig` + +Next, we should have a look at any relevant configuration settings (i.e., +settings readable and settable from `git config`). This is done by providing a +callback to `git_config()`; within that callback, you can also invoke methods +from other components you may need that need to intercept these options. Your +callback will be invoked once per each configuration value which Git knows about +(global, local, worktree, etc.). + +Similarly to the default values, we don't have anything to do here yet +ourselves; however, we should call `git_default_config()` if we aren't calling +any other existing config callbacks. + +Add a new function to `builtin/walken.c`: + +---- +static int git_walken_config(const char *var, const char *value, void *cb) +{ + /* + * For now, we don't have any custom configuration, so fall back to + * the default config. + */ + return git_default_config(var, value, cb); +} +---- + +Make sure to invoke `git_config()` with it in your `cmd_walken()`: + +---- +int cmd_walken(int argc, const char **argv, const char *prefix) +{ + ... + + git_config(git_walken_config, NULL); + + ... +} +---- + +==== Setting Up `rev_info` + +Now that we've gathered external configuration and options, it's time to +initialize the `rev_info` object which we will use to perform the walk. This is +typically done by calling `repo_init_revisions()` with the repository you intend +to target, as well as the `prefix` argument of `cmd_walken` and your `rev_info` +struct. + +Add the `struct rev_info` and the `repo_init_revisions()` call: +---- +int cmd_walken(int argc, const char **argv, const char *prefix) +{ + /* This can go wherever you like in your declarations.*/ + struct rev_info rev; + ... + + /* This should go after the git_config() call. */ + repo_init_revisions(the_repository, &rev, prefix); + + ... +} +---- + +==== Tweaking `rev_info` For the Walk + +We're getting close, but we're still not quite ready to go. Now that `rev` is +initialized, we can modify it to fit our needs. This is usually done within a +helper for clarity, so let's add one: + +---- +static void final_rev_info_setup(struct rev_info *rev) +{ + /* + * We want to mimic the appearance of `git log --oneline`, so let's + * force oneline format. + */ + get_commit_format("oneline", rev); + + /* Start our object walk at HEAD. */ + add_head_to_pending(rev); +} +---- + +[NOTE] +==== +Instead of using the shorthand `add_head_to_pending()`, you could do +something like this: +---- + struct setup_revision_opt opt; + + memset(&opt, 0, sizeof(opt)); + opt.def = "HEAD"; + opt.revarg_opt = REVARG_COMMITTISH; + setup_revisions(argc, argv, rev, &opt); +---- +Using a `setup_revision_opt` gives you finer control over your walk's starting +point. +==== + +Then let's invoke `final_rev_info_setup()` after the call to +`repo_init_revisions()`: + +---- +int cmd_walken(int argc, const char **argv, const char *prefix) +{ + ... + + final_rev_info_setup(&rev); + + ... +} +---- + +Later, we may wish to add more arguments to `final_rev_info_setup()`. But for +now, this is all we need. + +==== Preparing `rev_info` For the Walk + +Now that `rev` is all initialized and configured, we've got one more setup step +before we get rolling. We can do this in a helper, which will both prepare the +`rev_info` for the walk, and perform the walk itself. Let's start the helper +with the call to `prepare_revision_walk()`, which can return an error without +dying on its own: + +---- +static void walken_commit_walk(struct rev_info *rev) +{ + if (prepare_revision_walk(rev)) + die(_("revision walk setup failed")); +} +---- + +NOTE: `die()` prints to `stderr` and exits the program. Since it will print to +`stderr` it's likely to be seen by a human, so we will localize it. + +==== Performing the Walk! + +Finally! We are ready to begin the walk itself. Now we can see that `rev_info` +can also be used as an iterator; we move to the next item in the walk by using +`get_revision()` repeatedly. Add the listed variable declarations at the top and +the walk loop below the `prepare_revision_walk()` call within your +`walken_commit_walk()`: + +---- +static void walken_commit_walk(struct rev_info *rev) +{ + struct commit *commit; + struct strbuf prettybuf = STRBUF_INIT; + + ... + + while ((commit = get_revision(rev))) { + if (!commit) + continue; + + strbuf_reset(&prettybuf); + pp_commit_easy(CMIT_FMT_ONELINE, commit, &prettybuf); + puts(prettybuf.buf); + } + strbuf_release(&prettybuf); +} +---- + +NOTE: `puts()` prints a `char*` to `stdout`. Since this is the part of the +command we expect to be machine-parsed, we're sending it directly to stdout. + +Give it a shot. + +---- +$ make +$ ./bin-wrappers/git walken +---- + +You should see all of the subject lines of all the commits in +your tree's history, in order, ending with the initial commit, "Initial revision +of "git", the information manager from hell". Congratulations! You've written +your first revision walk. You can play with printing some additional fields +from each commit if you're curious; have a look at the functions available in +`commit.h`. + +=== Adding a Filter + +Next, let's try to filter the commits we see based on their author. This is +equivalent to running `git log --author=<pattern>`. We can add a filter by +modifying `rev_info.grep_filter`, which is a `struct grep_opt`. + +First some setup. Add `init_grep_defaults()` to `init_walken_defaults()` and add +`grep_config()` to `git_walken_config()`: + +---- +static void init_walken_defaults(void) +{ + init_grep_defaults(the_repository); +} + +... + +static int git_walken_config(const char *var, const char *value, void *cb) +{ + grep_config(var, value, cb); + return git_default_config(var, value, cb); +} +---- + +Next, we can modify the `grep_filter`. This is done with convenience functions +found in `grep.h`. For fun, we're filtering to only commits from folks using a +`gmail.com` email address - a not-very-precise guess at who may be working on +Git as a hobby. Since we're checking the author, which is a specific line in the +header, we'll use the `append_header_grep_pattern()` helper. We can use +the `enum grep_header_field` to indicate which part of the commit header we want +to search. + +In `final_rev_info_setup()`, add your filter line: + +---- +static void final_rev_info_setup(int argc, const char **argv, + const char *prefix, struct rev_info *rev) +{ + ... + + append_header_grep_pattern(&rev->grep_filter, GREP_HEADER_AUTHOR, + "gmail"); + compile_grep_patterns(&rev->grep_filter); + + ... +} +---- + +`append_header_grep_pattern()` adds your new "gmail" pattern to `rev_info`, but +it won't work unless we compile it with `compile_grep_patterns()`. + +NOTE: If you are using `setup_revisions()` (for example, if you are passing a +`setup_revision_opt` instead of using `add_head_to_pending()`), you don't need +to call `compile_grep_patterns()` because `setup_revisions()` calls it for you. + +NOTE: We could add the same filter via the `append_grep_pattern()` helper if we +wanted to, but `append_header_grep_pattern()` adds the `enum grep_context` and +`enum grep_pat_token` for us. + +=== Changing the Order + +There are a few ways that we can change the order of the commits during a +revision walk. Firstly, we can use the `enum rev_sort_order` to choose from some +typical orderings. + +`topo_order` is the same as `git log --topo-order`: we avoid showing a parent +before all of its children have been shown, and we avoid mixing commits which +are in different lines of history. (`git help log`'s section on `--topo-order` +has a very nice diagram to illustrate this.) + +Let's see what happens when we run with `REV_SORT_BY_COMMIT_DATE` as opposed to +`REV_SORT_BY_AUTHOR_DATE`. Add the following: + +---- +static void final_rev_info_setup(int argc, const char **argv, + const char *prefix, struct rev_info *rev) +{ + ... + + rev->topo_order = 1; + rev->sort_order = REV_SORT_BY_COMMIT_DATE; + + ... +} +---- + +Let's output this into a file so we can easily diff it with the walk sorted by +author date. + +---- +$ make +$ ./bin-wrappers/git walken > commit-date.txt +---- + +Then, let's sort by author date and run it again. + +---- +static void final_rev_info_setup(int argc, const char **argv, + const char *prefix, struct rev_info *rev) +{ + ... + + rev->topo_order = 1; + rev->sort_order = REV_SORT_BY_AUTHOR_DATE; + + ... +} +---- + +---- +$ make +$ ./bin-wrappers/git walken > author-date.txt +---- + +Finally, compare the two. This is a little less helpful without object names or +dates, but hopefully we get the idea. + +---- +$ diff -u commit-date.txt author-date.txt +---- + +This display indicates that commits can be reordered after they're written, for +example with `git rebase`. + +Let's try one more reordering of commits. `rev_info` exposes a `reverse` flag. +Set that flag somewhere inside of `final_rev_info_setup()`: + +---- +static void final_rev_info_setup(int argc, const char **argv, const char *prefix, + struct rev_info *rev) +{ + ... + + rev->reverse = 1; + + ... +} +---- + +Run your walk again and note the difference in order. (If you remove the grep +pattern, you should see the last commit this call gives you as your current +HEAD.) + +== Basic Object Walk + +So far we've been walking only commits. But Git has more types of objects than +that! Let's see if we can walk _all_ objects, and find out some information +about each one. + +We can base our work on an example. `git pack-objects` prepares all kinds of +objects for packing into a bitmap or packfile. The work we are interested in +resides in `builtins/pack-objects.c:get_object_list()`; examination of that +function shows that the all-object walk is being performed by +`traverse_commit_list()` or `traverse_commit_list_filtered()`. Those two +functions reside in `list-objects.c`; examining the source shows that, despite +the name, these functions traverse all kinds of objects. Let's have a look at +the arguments to `traverse_commit_list_filtered()`, which are a superset of the +arguments to the unfiltered version. + +- `struct list_objects_filter_options *filter_options`: This is a struct which + stores a filter-spec as outlined in `Documentation/rev-list-options.txt`. +- `struct rev_info *revs`: This is the `rev_info` used for the walk. +- `show_commit_fn show_commit`: A callback which will be used to handle each + individual commit object. +- `show_object_fn show_object`: A callback which will be used to handle each + non-commit object (so each blob, tree, or tag). +- `void *show_data`: A context buffer which is passed in turn to `show_commit` + and `show_object`. +- `struct oidset *omitted`: A linked-list of object IDs which the provided + filter caused to be omitted. + +It looks like this `traverse_commit_list_filtered()` uses callbacks we provide +instead of needing us to call it repeatedly ourselves. Cool! Let's add the +callbacks first. + +For the sake of this tutorial, we'll simply keep track of how many of each kind +of object we find. At file scope in `builtin/walken.c` add the following +tracking variables: + +---- +static int commit_count; +static int tag_count; +static int blob_count; +static int tree_count; +---- + +Commits are handled by a different callback than other objects; let's do that +one first: + +---- +static void walken_show_commit(struct commit *cmt, void *buf) +{ + commit_count++; +} +---- + +The `cmt` argument is fairly self-explanatory. But it's worth mentioning that +the `buf` argument is actually the context buffer that we can provide to the +traversal calls - `show_data`, which we mentioned a moment ago. + +Since we have the `struct commit` object, we can look at all the same parts that +we looked at in our earlier commit-only walk. For the sake of this tutorial, +though, we'll just increment the commit counter and move on. + +The callback for non-commits is a little different, as we'll need to check +which kind of object we're dealing with: + +---- +static void walken_show_object(struct object *obj, const char *str, void *buf) +{ + switch (obj->type) { + case OBJ_TREE: + tree_count++; + break; + case OBJ_BLOB: + blob_count++; + break; + case OBJ_TAG: + tag_count++; + break; + case OBJ_COMMIT: + BUG("unexpected commit object in walken_show_object\n"); + default: + BUG("unexpected object type %s in walken_show_object\n", + type_name(obj->type)); + } +} +---- + +Again, `obj` is fairly self-explanatory, and we can guess that `buf` is the same +context pointer that `walken_show_commit()` receives: the `show_data` argument +to `traverse_commit_list()` and `traverse_commit_list_filtered()`. Finally, +`str` contains the name of the object, which ends up being something like +`foo.txt` (blob), `bar/baz` (tree), or `v1.2.3` (tag). + +To help assure us that we aren't double-counting commits, we'll include some +complaining if a commit object is routed through our non-commit callback; we'll +also complain if we see an invalid object type. Since those two cases should be +unreachable, and would only change in the event of a semantic change to the Git +codebase, we complain by using `BUG()` - which is a signal to a developer that +the change they made caused unintended consequences, and the rest of the +codebase needs to be updated to understand that change. `BUG()` is not intended +to be seen by the public, so it is not localized. + +Our main object walk implementation is substantially different from our commit +walk implementation, so let's make a new function to perform the object walk. We +can perform setup which is applicable to all objects here, too, to keep separate +from setup which is applicable to commit-only walks. + +We'll start by enabling all types of objects in the `struct rev_info`. We'll +also turn on `tree_blobs_in_commit_order`, which means that we will walk a +commit's tree and everything it points to immediately after we find each commit, +as opposed to waiting for the end and walking through all trees after the commit +history has been discovered. With the appropriate settings configured, we are +ready to call `prepare_revision_walk()`. + +---- +static void walken_object_walk(struct rev_info *rev) +{ + rev->tree_objects = 1; + rev->blob_objects = 1; + rev->tag_objects = 1; + rev->tree_blobs_in_commit_order = 1; + + if (prepare_revision_walk(rev)) + die(_("revision walk setup failed")); + + commit_count = 0; + tag_count = 0; + blob_count = 0; + tree_count = 0; +---- + +Let's start by calling just the unfiltered walk and reporting our counts. +Complete your implementation of `walken_object_walk()`: + +---- + traverse_commit_list(rev, walken_show_commit, walken_show_object, NULL); + + printf("commits %d\nblobs %d\ntags %d\ntrees %d\n", commit_count, + blob_count, tag_count, tree_count); +} +---- + +NOTE: This output is intended to be machine-parsed. Therefore, we are not +sending it to `trace_printf()`, and we are not localizing it - we need scripts +to be able to count on the formatting to be exactly the way it is shown here. +If we were intending this output to be read by humans, we would need to localize +it with `_()`. + +Finally, we'll ask `cmd_walken()` to use the object walk instead. Discussing +command line options is out of scope for this tutorial, so we'll just hardcode +a branch we can change at compile time. Where you call `final_rev_info_setup()` +and `walken_commit_walk()`, instead branch like so: + +---- + if (1) { + add_head_to_pending(&rev); + walken_object_walk(&rev); + } else { + final_rev_info_setup(argc, argv, prefix, &rev); + walken_commit_walk(&rev); + } +---- + +NOTE: For simplicity, we've avoided all the filters and sorts we applied in +`final_rev_info_setup()` and simply added `HEAD` to our pending queue. If you +want, you can certainly use the filters we added before by moving +`final_rev_info_setup()` out of the conditional and removing the call to +`add_head_to_pending()`. + +Now we can try to run our command! It should take noticeably longer than the +commit walk, but an examination of the output will give you an idea why. Your +output should look similar to this example, but with different counts: + +---- +Object walk completed. Found 55733 commits, 100274 blobs, 0 tags, and 104210 trees. +---- + +This makes sense. We have more trees than commits because the Git project has +lots of subdirectories which can change, plus at least one tree per commit. We +have no tags because we started on a commit (`HEAD`) and while tags can point to +commits, commits can't point to tags. + +NOTE: You will have different counts when you run this yourself! The number of +objects grows along with the Git project. + +=== Adding a Filter + +There are a handful of filters that we can apply to the object walk laid out in +`Documentation/rev-list-options.txt`. These filters are typically useful for +operations such as creating packfiles or performing a partial clone. They are +defined in `list-objects-filter-options.h`. For the purposes of this tutorial we +will use the "tree:1" filter, which causes the walk to omit all trees and blobs +which are not directly referenced by commits reachable from the commit in +`pending` when the walk begins. (`pending` is the list of objects which need to +be traversed during a walk; you can imagine a breadth-first tree traversal to +help understand. In our case, that means we omit trees and blobs not directly +referenced by `HEAD` or `HEAD`'s history, because we begin the walk with only +`HEAD` in the `pending` list.) + +First, we'll need to `#include "list-objects-filter-options.h`" and set up the +`struct list_objects_filter_options` at the top of the function. + +---- +static void walken_object_walk(struct rev_info *rev) +{ + struct list_objects_filter_options filter_options = {}; + + ... +---- + +For now, we are not going to track the omitted objects, so we'll replace those +parameters with `NULL`. For the sake of simplicity, we'll add a simple +build-time branch to use our filter or not. Replace the line calling +`traverse_commit_list()` with the following, which will remind us which kind of +walk we've just performed: + +---- + if (0) { + /* Unfiltered: */ + trace_printf(_("Unfiltered object walk.\n")); + traverse_commit_list(rev, walken_show_commit, + walken_show_object, NULL); + } else { + trace_printf( + _("Filtered object walk with filterspec 'tree:1'.\n")); + parse_list_objects_filter(&filter_options, "tree:1"); + + traverse_commit_list_filtered(&filter_options, rev, + walken_show_commit, walken_show_object, NULL, NULL); + } +---- + +`struct list_objects_filter_options` is usually built directly from a command +line argument, so the module provides an easy way to build one from a string. +Even though we aren't taking user input right now, we can still build one with +a hardcoded string using `parse_list_objects_filter()`. + +With the filter spec "tree:1", we are expecting to see _only_ the root tree for +each commit; therefore, the tree object count should be less than or equal to +the number of commits. (For an example of why that's true: `git commit --revert` +points to the same tree object as its grandparent.) + +=== Counting Omitted Objects + +We also have the capability to enumerate all objects which were omitted by a +filter, like with `git log --filter=<spec> --filter-print-omitted`. Asking +`traverse_commit_list_filtered()` to populate the `omitted` list means that our +object walk does not perform any better than an unfiltered object walk; all +reachable objects are walked in order to populate the list. + +First, add the `struct oidset` and related items we will use to iterate it: + +---- +static void walken_object_walk( + ... + + struct oidset omitted; + struct oidset_iter oit; + struct object_id *oid = NULL; + int omitted_count = 0; + oidset_init(&omitted, 0); + + ... +---- + +Modify the call to `traverse_commit_list_filtered()` to include your `omitted` +object: + +---- + ... + + traverse_commit_list_filtered(&filter_options, rev, + walken_show_commit, walken_show_object, NULL, &omitted); + + ... +---- + +Then, after your traversal, the `oidset` traversal is pretty straightforward. +Count all the objects within and modify the print statement: + +---- + /* Count the omitted objects. */ + oidset_iter_init(&omitted, &oit); + + while ((oid = oidset_iter_next(&oit))) + omitted_count++; + + printf("commits %d\nblobs %d\ntags %d\ntrees%d\nomitted %d\n", + commit_count, blob_count, tag_count, tree_count, omitted_count); +---- + +By running your walk with and without the filter, you should find that the total +object count in each case is identical. You can also time each invocation of +the `walken` subcommand, with and without `omitted` being passed in, to confirm +to yourself the runtime impact of tracking all omitted objects. + +=== Changing the Order + +Finally, let's demonstrate that you can also reorder walks of all objects, not +just walks of commits. First, we'll make our handlers chattier - modify +`walken_show_commit()` and `walken_show_object()` to print the object as they +go: + +---- +static void walken_show_commit(struct commit *cmt, void *buf) +{ + trace_printf("commit: %s\n", oid_to_hex(&cmt->object.oid)); + commit_count++; +} + +static void walken_show_object(struct object *obj, const char *str, void *buf) +{ + trace_printf("%s: %s\n", type_name(obj->type), oid_to_hex(&obj->oid)); + + ... +} +---- + +NOTE: Since we will be examining this output directly as humans, we'll use +`trace_printf()` here. Additionally, since this change introduces a significant +number of printed lines, using `trace_printf()` will allow us to easily silence +those lines without having to recompile. + +(Leave the counter increment logic in place.) + +With only that change, run again (but save yourself some scrollback): + +---- +$ GIT_TRACE=1 ./bin-wrappers/git walken | head -n 10 +---- + +Take a look at the top commit with `git show` and the object ID you printed; it +should be the same as the output of `git show HEAD`. + +Next, let's change a setting on our `struct rev_info` within +`walken_object_walk()`. Find where you're changing the other settings on `rev`, +such as `rev->tree_objects` and `rev->tree_blobs_in_commit_order`, and add the +`reverse` setting at the bottom: + +---- + ... + + rev->tree_objects = 1; + rev->blob_objects = 1; + rev->tag_objects = 1; + rev->tree_blobs_in_commit_order = 1; + rev->reverse = 1; + + ... +---- + +Now, run again, but this time, let's grab the last handful of objects instead +of the first handful: + +---- +$ make +$ GIT_TRACE=1 ./bin-wrappers git walken | tail -n 10 +---- + +The last commit object given should have the same OID as the one we saw at the +top before, and running `git show <oid>` with that OID should give you again +the same results as `git show HEAD`. Furthermore, if you run and examine the +first ten lines again (with `head` instead of `tail` like we did before applying +the `reverse` setting), you should see that now the first commit printed is the +initial commit, `e83c5163`. + +== Wrapping Up + +Let's review.

If +the skip-worktree bit is set, then the file is ignored in the working +directory. Git will not populate the contents of those files, which +makes a sparse checkout helpful when working in a repository with many +files, but only a few are important to the current user. + +The `$GIT_DIR/info/sparse-checkout` file is used to define the +skip-worktree reference bitmap. When Git updates the working +directory, it updates the skip-worktree bits in the index based +on this file. The files matching the patterns in the file will +appear in the working directory, and the rest will not. + +To enable the sparse-checkout feature, run `git sparse-checkout init` to +initialize a simple sparse-checkout file and enable the `core.sparseCheckout` +config setting. Then, run `git sparse-checkout set` to modify the patterns in +the sparse-checkout file. + +To repopulate the working directory with all files, use the +`git sparse-checkout disable` command. + + +FULL PATTERN SET +---------------- + +By default, the sparse-checkout file uses the same syntax as `.gitignore` +files. + +While `$GIT_DIR/info/sparse-checkout` is usually used to specify what +files are included, you can also specify what files are _not_ included, +using negative patterns. For example, to remove the file `unwanted`: + +---------------- +/* +!unwanted +---------------- + + +CONE PATTERN SET +---------------- + +The full pattern set allows for arbitrary pattern matches and complicated +inclusion/exclusion rules. These can result in O(N*M) pattern matches when +updating the index, where N is the number of patterns and M is the number +of paths in the index. To combat this performance issue, a more restricted +pattern set is allowed when `core.spareCheckoutCone` is enabled. + +The accepted patterns in the cone pattern set are: + +1. *Recursive:* All paths inside a directory are included. + +2. *Parent:* All files immediately inside a directory are included. + +In addition to the above two patterns, we also expect that all files in the +root directory are included. If a recursive pattern is added, then all +leading directories are added as parent patterns. + +By default, when running `git sparse-checkout init`, the root directory is +added as a parent pattern. At this point, the sparse-checkout file contains +the following patterns: + +---------------- +/* +!/*/ +---------------- + +This says "include everything in root, but nothing two levels below root." +If we then add the folder `A/B/C` as a recursive pattern, the folders `A` and +`A/B` are added as parent patterns. The resulting sparse-checkout file is +now + +---------------- +/* +!/*/ +/A/ +!/A/*/ +/A/B/ +!/A/B/*/ +/A/B/C/ +---------------- + +Here, order matters, so the negative patterns are overridden by the positive +patterns that appear lower in the file. + +If `core.sparseCheckoutCone=true`, then Git will parse the sparse-checkout file +expecting patterns of these types.

If the variable had no - value specified, the value will be NULL (typically this means it - should be interpreted as boolean true). - -- a void pointer passed in by the caller of the config API; this can - contain callback-specific data - -A config callback should return 0 for success, or -1 if the variable -could not be parsed properly. - -Basic Config Querying ---------------------- - -Most programs will simply want to look up variables in all config files -that Git knows about, using the normal precedence rules. To do this, -call `git_config` with a callback function and void data pointer. - -`git_config` will read all config sources in order of increasing -priority. Thus a callback should typically overwrite previously-seen -entries with new ones (e.g., if both the user-wide `~/.gitconfig` and -repo-specific `.git/config` contain `color.ui`, the config machinery -will first feed the user-wide one to the callback, and then the -repo-specific one; by overwriting, the higher-priority repo-specific -value is left at the end). - -The `config_with_options` function lets the caller examine config -while adjusting some of the default behavior of `git_config`. It should -almost never be used by "regular" Git code that is looking up -configuration variables. It is intended for advanced callers like -`git-config`, which are intentionally tweaking the normal config-lookup -process. It takes two extra parameters: - -`config_source`:: -If this parameter is non-NULL, it specifies the source to parse for -configuration, rather than looking in the usual files. See `struct -git_config_source` in `config.h` for details. Regular `git_config` defaults -to `NULL`. - -`opts`:: -Specify options to adjust the behavior of parsing config files. See `struct -config_options` in `config.h` for details. As an example: regular `git_config` -sets `opts.respect_includes` to `1` by default. - -Reading Specific Files ----------------------- - -To read a specific file in git-config format, use -`git_config_from_file`. This takes the same callback and data parameters -as `git_config`. - -Querying For Specific Variables -------------------------------- - -For programs wanting to query for specific variables in a non-callback -manner, the config API provides two functions `git_config_get_value` -and `git_config_get_value_multi`. They both read values from an internal -cache generated previously from reading the config files. - -`int git_config_get_value(const char *key, const char **value)`:: - - Finds the highest-priority value for the configuration variable `key`, - stores the pointer to it in `value` and returns 0. When the - configuration variable `key` is not found, returns 1 without touching - `value`. The caller should not free or modify `value`, as it is owned - by the cache. - -`const struct string_list *git_config_get_value_multi(const char *key)`:: - - Finds and returns the value list, sorted in order of increasing priority - for the configuration variable `key`. When the configuration variable - `key` is not found, returns NULL. The caller should not free or modify - the returned pointer, as it is owned by the cache. - -`void git_config_clear(void)`:: - - Resets and invalidates the config cache. - -The config API also provides type specific API functions which do conversion -as well as retrieval for the queried variable, including: - -`int git_config_get_int(const char *key, int *dest)`:: - - Finds and parses the value to an integer for the configuration variable - `key`. Dies on error; otherwise, stores the value of the parsed integer in - `dest` and returns 0. When the configuration variable `key` is not found, - returns 1 without touching `dest`. - -`int git_config_get_ulong(const char *key, unsigned long *dest)`:: - - Similar to `git_config_get_int` but for unsigned longs. - -`int git_config_get_bool(const char *key, int *dest)`:: - - Finds and parses the value into a boolean value, for the configuration - variable `key` respecting keywords like "true" and "false". Integer - values are converted into true/false values (when they are non-zero or - zero, respectively). Other values cause a die(). If parsing is successful, - stores the value of the parsed result in `dest` and returns 0. When the - configuration variable `key` is not found, returns 1 without touching - `dest`. - -`int git_config_get_bool_or_int(const char *key, int *is_bool, int *dest)`:: - - Similar to `git_config_get_bool`, except that integers are copied as-is, - and `is_bool` flag is unset. - -`int git_config_get_maybe_bool(const char *key, int *dest)`:: - - Similar to `git_config_get_bool`, except that it returns -1 on error - rather than dying. - -`int git_config_get_string_const(const char *key, const char **dest)`:: - - Allocates and copies the retrieved string into the `dest` parameter for - the configuration variable `key`; if NULL string is given, prints an - error message and returns -1. When the configuration variable `key` is - not found, returns 1 without touching `dest`. - -`int git_config_get_string(const char *key, char **dest)`:: - - Similar to `git_config_get_string_const`, except that retrieved value - copied into the `dest` parameter is a mutable string. - -`int git_config_get_pathname(const char *key, const char **dest)`:: - - Similar to `git_config_get_string`, but expands `~` or `~user` into - the user's home directory when found at the beginning of the path. - -`git_die_config(const char *key, const char *err, ...)`:: - - First prints the error message specified by the caller in `err` and then - dies printing the line number and the file name of the highest priority - value for the configuration variable `key`. - -`void git_die_config_linenr(const char *key, const char *filename, int linenr)`:: - - Helper function which formats the die error message according to the - parameters entered. Used by `git_die_config()`. It can be used by callers - handling `git_config_get_value_multi()` to print the correct error message - for the desired value. - -See test-config.c for usage examples. - -Value Parsing Helpers ---------------------- - -To aid in parsing string values, the config API provides callbacks with -a number of helper functions, including: - -`git_config_int`:: -Parse the string to an integer, including unit factors. Dies on error; -otherwise, returns the parsed result. - -`git_config_ulong`:: -Identical to `git_config_int`, but for unsigned longs. - -`git_config_bool`:: -Parse a string into a boolean value, respecting keywords like "true" and -"false". Integer values are converted into true/false values (when they -are non-zero or zero, respectively). Other values cause a die(). If -parsing is successful, the return value is the result. - -`git_config_bool_or_int`:: -Same as `git_config_bool`, except that integers are returned as-is, and -an `is_bool` flag is unset. - -`git_parse_maybe_bool`:: -Same as `git_config_bool`, except that it returns -1 on error rather -than dying. - -`git_config_string`:: -Allocates and copies the value string into the `dest` parameter; if no -string is given, prints an error message and returns -1. - -`git_config_pathname`:: -Similar to `git_config_string`, but expands `~` or `~user` into the -user's home directory when found at the beginning of the path. - -Include Directives ------------------- - -By default, the config parser does not respect include directives. -However, a caller can use the special `git_config_include` wrapper -callback to support them. To do so, you simply wrap your "real" callback -function and data pointer in a `struct config_include_data`, and pass -the wrapper to the regular config-reading functions. For example: - -------------------------------------------- -int read_file_with_include(const char *file, config_fn_t fn, void *data) -{ - struct config_include_data inc = CONFIG_INCLUDE_INIT; - inc.fn = fn; - inc.data = data; - return git_config_from_file(git_config_include, file, &inc); -} -------------------------------------------- - -`git_config` respects includes automatically. The lower-level -`git_config_from_file` does not. - -Custom Configsets ------------------ - -A `config_set` can be used to construct an in-memory cache for -config-like files that the caller specifies (i.e., files like `.gitmodules`, -`~/.gitconfig` etc.). For example, - ----------------------------------------- -struct config_set gm_config; -git_configset_init(&gm_config); -int b; -/* we add config files to the config_set */ -git_configset_add_file(&gm_config, ".gitmodules"); -git_configset_add_file(&gm_config, ".gitmodules_alt"); - -if (!git_configset_get_bool(gm_config, "submodule.frotz.ignore", &b)) { - /* hack hack hack */ -} - -/* when we are done with the configset */ -git_configset_clear(&gm_config); ----------------------------------------- - -Configset API provides functions for the above mentioned work flow, including: - -`void git_configset_init(struct config_set *cs)`:: - - Initializes the config_set `cs`. - -`int git_configset_add_file(struct config_set *cs, const char *filename)`:: - - Parses the file and adds the variable-value pairs to the `config_set`, - dies if there is an error in parsing the file. Returns 0 on success, or - -1 if the file does not exist or is inaccessible. The user has to decide - if he wants to free the incomplete configset or continue using it when - the function returns -1. - -`int git_configset_get_value(struct config_set *cs, const char *key, const char **value)`:: - - Finds the highest-priority value for the configuration variable `key` - and config set `cs`, stores the pointer to it in `value` and returns 0. - When the configuration variable `key` is not found, returns 1 without - touching `value`. The caller should not free or modify `value`, as it - is owned by the cache. - -`const struct string_list *git_configset_get_value_multi(struct config_set *cs, const char *key)`:: - - Finds and returns the value list, sorted in order of increasing priority - for the configuration variable `key` and config set `cs`. When the - configuration variable `key` is not found, returns NULL. The caller - should not free or modify the returned pointer, as it is owned by the cache. - -`void git_configset_clear(struct config_set *cs)`:: - - Clears `config_set` structure, removes all saved variable-value pairs. - -In addition to above functions, the `config_set` API provides type specific -functions in the vein of `git_config_get_int` and family but with an extra -parameter, pointer to struct `config_set`. -They all behave similarly to the `git_config_get*()` family described in -"Querying For Specific Variables" above. - -Writing Config Files --------------------- - -Git gives multiple entry points in the Config API to write config values to -files namely `git_config_set_in_file` and `git_config_set`, which write to -a specific config file or to `.git/config` respectively. They both take a -key/value pair as parameter. -In the end they both call `git_config_set_multivar_in_file` which takes four -parameters: - -- the name of the file, as a string, to which key/value pairs will be written. - -- the name of key, as a string. This is in canonical "flat" form: the section, - subsection, and variable segments will be separated by dots, and the section - and variable segments will be all lowercase. - E.g., `core.ignorecase`, `diff.SomeType.textconv`. - -- the value of the variable, as a string. If value is equal to NULL, it will - remove the matching key from the config file. - -- the value regex, as a string. It will disregard key/value pairs where value - does not match. - -- a multi_replace value, as an int. If value is equal to zero, nothing or only - one matching key/value is replaced, else all matching key/values (regardless - how many) are removed, before the new pair is written. - -It returns 0 on success. - -Also, there are functions `git_config_rename_section` and -`git_config_rename_section_in_file` with parameters `old_name` and `new_name` -for renaming or removing sections in the config files. If NULL is passed -through `new_name` parameter, the section will be removed from the config file. diff --git a/Documentation/technical/api-credentials.txt b/Documentation/technical/api-credentials.txt deleted file mode 100644 index 75368f26ca..0000000000 --- a/Documentation/technical/api-credentials.txt +++ /dev/null @@ -1,271 +0,0 @@ -credentials API -=============== - -The credentials API provides an abstracted way of gathering username and -password credentials from the user (even though credentials in the wider -world can take many forms, in this document the word "credential" always -refers to a username and password pair). - -This document describes two interfaces: the C API that the credential -subsystem provides to the rest of Git, and the protocol that Git uses to -communicate with system-specific "credential helpers".

If the helper string begins with "!", it is considered a shell + * snippet, and everything after the "!" becomes the command. + * + * 2. Otherwise, if the helper string begins with an absolute path, the + * verbatim helper string becomes the command. + * + * 3. Otherwise, the string "git credential-" is prepended to the helper + * string, and the result becomes the command. + * + * The resulting command then has an "operation" argument appended to it + * (see below for details), and the result is executed by the shell. + * + * Here are some example specifications: + * + * ---------------------------------------------------- + * # run "git credential-foo" + * foo + * + * # same as above, but pass an argument to the helper + * foo --bar=baz + * + * # the arguments are parsed by the shell, so use shell + * # quoting if necessary + * foo --bar="whitespace arg" + * + * # you can also use an absolute path, which will not use the git wrapper + * /path/to/my/helper --with-arguments + * + * # or you can specify your own shell snippet + * !f() { echo "password=`cat $HOME/.secret`"; }; f + * ---------------------------------------------------- + * + * Generally speaking, rule (3) above is the simplest for users to specify. + * Authors of credential helpers should make an effort to assist their + * users by naming their program "git-credential-$NAME", and putting it in + * the $PATH or $GIT_EXEC_PATH during installation, which will allow a user + * to enable it with `git config credential.helper $NAME`. + * + * When a helper is executed, it will have one "operation" argument + * appended to its command line, which is one of: + * + * `get`:: + * + * Return a matching credential, if any exists. + * + * `store`:: + * + * Store the credential, if applicable to the helper. + * + * `erase`:: + * + * Remove a matching credential, if any, from the helper's storage. + * + * The details of the credential will be provided on the helper's stdin + * stream.
