I.e. we've documented it as ignoring non-option arguments, let's have it error out instead. As with other changes made in 62f035aee3f (Merge branch 'ab/help-config-vars', 2021-10-13) this is technically a change in behavior, but in practice it's just a bug fix. We were ignoring this before, but by erroring we can simplify our documentation and synopsis, as well as avoid user confusion as they wonder what the difference between e.g. "git help --all" and "git help --all status" is (there wasn't any difference).

2022-02-20sparse-checkout: reject arguments in cone-mode that look like patternsLibravatar Elijah Newren1-0/+11
In sparse-checkout add/set under cone mode, the arguments passed are supposed to be directories rather than gitignore-style patterns. However, given the amount of effort spent in the manual discussing patterns, it is easy for users to assume they need to pass patterns such as /foo/* or !/bar/*/ or perhaps they really do ignore the directory rule and specify a random gitignore-style pattern like *.c To help catch such mistakes, throw an error if any of the positional arguments: * starts with any of '/!' * contains any of '*?[]' Inform users they can pass --skip-checks if they have a directory that really does have such special characters in its name. (We exclude '\' because of sparse-checkout's special handling of backslashes; see the MINGW test in t1091.46.)

2022-02-20sparse-checkout: error or warn when given individual filesLibravatar Elijah Newren1-6/+36
The set and add subcommands accept multiple positional arguments. The meaning of these arguments differs slightly in the two modes: Cone mode only accepts directories. If given a file, it would previously treat it as a directory, causing not just the file itself to be included but all sibling files as well -- likely against users' expectations. Throw an error if the specified path is a file in the index. Provide a --skip-checks argument to allow users to override (e.g. for the case when the given path IS a directory on another branch). Non-cone mode accepts general gitignore patterns. There are many reasons to avoid this mode, but one possible reason to use it instead of cone mode: to be able to select individual files within a directory. However, if a file is passed to set/add in non-cone mode, you won't be selecting a single file, you'll be selecting a file with the same name in any directory. Thus users will likely want to prefix any paths they specify with a leading '/' character; warn users if the patterns they specify exactly name a file because it means they are likely missing such a leading slash.

2022-02-20sparse-checkout: pay attention to prefix for {set, add}Libravatar Elijah Newren1-0/+26
In cone mode, non-option arguments to set & add are clearly paths, and as such, we should pay attention to prefix. In non-cone mode, it is not clear that folks intend to provide paths since the inputs are gitignore-style patterns. Paying attention to prefix would prevent folks from doing things like git sparse-checkout add /.gitattributes git sparse-checkout add '/toplevel-dir/*' In fact, the former will result in fatal: '/.gitattributes' is outside repository... while the later will result in fatal: Invalid path '/toplevel-dir': No such file or directory despite the fact that both are valid gitignore-style patterns that would select real files if added to the sparse-checkout file. This might lead people to just use the path without the leading slash, potentially resulting in them grabbing files with the same name throughout the directory hierarchy contrary to their expectations. See also [1] and [2]. Adding prefix seems to just be fraught with error; so for now simply throw an error in non-cone mode when sparse-checkout set/add are run from a subdirectory.

2022-02-20sparse-checkout: correctly set non-cone mode when expectedLibravatar Elijah Newren1-0/+1
commit f2e3a218e8 ("sparse-checkout: enable `set` to initialize sparse-checkout mode", 2021-12-14) made the `set` command able to initialize sparse-checkout mode, but it also had to function when sparse-checkout mode was already setup and the user just wanted to change the sparsity paths. So, if the user passed --cone or --no-cone, then we should override the current setting, but if they didn't pass either, we should use whatever the current cone mode setting is. Unfortunately, there was a small error in the logic in that it would not set the in-memory cone mode value (core_sparse_checkout_one) when --no-cone was specified, but since it did set the config setting on disk, any subsequent git invocation would correctly get non-cone mode. As such, the error did not previously matter. However, a subsequent commit will add some logic that depends on core_sparse_checkout_cone being set to the correct mode, so make sure it is set consistently with the config values we will be writing to disk.

2022-02-18cat-file: add --batch-command modeLibravatar John Cai1-1/+143
Add a new flag --batch-command that accepts commands and arguments from stdin, similar to git-update-ref --stdin. At GitLab, we use a pair of long running cat-file processes when accessing object content. One for iterating over object metadata with --batch-check, and the other to grab object contents with --batch. However, if we had --batch-command, we wouldn't need to keep both processes around, and instead just have one --batch-command process where we can flip between getting object info, and getting object contents. Since we have a pair of cat-file processes per repository, this means we can get rid of roughly half of long lived git cat-file processes. Given there are many repositories being accessed at any given time, this can lead to huge savings. git cat-file --batch-command will enter an interactive command mode whereby the user can enter in commands and their arguments that get queued in memory: <command1> [arg1] [arg2] LF <command2> [arg1] [arg2] LF When --buffer mode is used, commands will be queued in memory until a flush command is issued that execute them: flush LF The reason for a flush command is that when a consumer process (A) talks to a git cat-file process (B) and interactively writes to and reads from it in --buffer mode, (A) needs to be able to control when the buffer is flushed to stdout. Currently, from (A)'s perspective, the only way is to either 1. kill (B)'s process 2. send an invalid object to stdin. 1. is not ideal from a performance perspective as it will require spawning a new cat-file process each time, and 2. is hacky and not a good long term solution. With this mechanism of queueing up commands and letting (A) issue a flush command, process (A) can control when the buffer is flushed and can guarantee it will receive all of the output when in --buffer mode. --batch-command also will not allow (B) to flush to stdout until a flush is received. This patch adds the basic structure for adding command which can be extended in the future to add more commands. It also adds the following two commands (on top of the flush command): contents <object> LF info <object> LF The contents command takes an <object> argument and prints out the object contents. The info command takes an <object> argument and prints out the object metadata. These can be used in the following way with --buffer: info <object> LF contents <object> LF contents <object> LF info <object> LF flush LF info <object> LF flush LF When used without --buffer: info <object> LF contents <object> LF contents <object> LF info <object> LF info <object> LF Helped-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: John Cai <johncai86@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-18cat-file: introduce batch_mode enum to replace print_contentsLibravatar John Cai1-4/+16
A future patch introduces a new --batch-command flag. Including --batch and --batch-check, we will have a total of three batch modes. print_contents is the only boolean on the batch_options sturct used to distinguish between the different modes. This makes the code harder to read. To reduce potential confusion, replace print_contents with an enum to help readability and clarity.
