docs: move protocol-related docs to man section 5

2022-08-04T21:12:23Z

Continue the move of existing Documentation/technical/* protocol and file-format documentation into our main documentation space. By moving the things that discuss the protocol we can properly link from e.g. lsrefs.unborn and protocol.version documentation to a manpage we build by default. So far we have been using the "gitformat-" prefix for the documentation we've been moving over from Documentation/technical/*, but for protocol documentation let's use "gitprotocol-*".

Merge branch 'sb/clone-origin'

2020-10-27T22:09:50Z

"git clone" learned clone.defaultremotename configuration variable to customize what nickname to use to call the remote the repository was cloned from. * sb/clone-origin: clone: allow configurable default for `-o`/`--origin` clone: read new remote name from remote_name instead of option_origin clone: validate --origin option before use refs: consolidate remote name validation remote: add tests for add and rename with invalid names clone: use more conventional config/option layering clone: add tests for --template and some disallowed option pairs

Merge branch 'jk/refspecs-negative'

2020-10-05T21:01:54Z

"git fetch" and "git push" support negative refspecs. * jk/refspecs-negative: refspec: add support for negative refspecs

refs: consolidate remote name validation

2020-10-01T05:09:13Z

In preparation for a future patch, extract from remote.c a function that validates possible remote names so that its rules can be used consistently in other places. Helped-by: Derrick Stolee Signed-off-by: Sean Barag Signed-off-by: Junio C Hamano

refspec: add support for negative refspecs

2020-09-30T21:52:00Z

Both fetch and push support pattern refspecs which allow fetching or pushing references that match a specific pattern. Because these patterns are globs, they have somewhat limited ability to express more complex situations. For example, suppose you wish to fetch all branches from a remote except for a specific one. To allow this, you must setup a set of refspecs which match only the branches you want. Because refspecs are either explicit name matches, or simple globs, many patterns cannot be expressed. Add support for a new type of refspec, referred to as "negative" refspecs. These are prefixed with a '^' and mean "exclude any ref matching this refspec". They can only have one "side" which always refers to the source. During a fetch, this refers to the name of the ref on the remote. During a push, this refers to the name of the ref on the local side. With negative refspecs, users can express more complex patterns. For example: git fetch origin refs/heads/*:refs/remotes/origin/* ^refs/heads/dontwant will fetch all branches on origin into remotes/origin, but will exclude fetching the branch named dontwant. Refspecs today are commutative, meaning that order doesn't expressly matter. Rather than forcing an implied order, negative refspecs will always be applied last. That is, in order to match, a ref must match at least one positive refspec, and match none of the negative refspecs. This is similar to how negative pathspecs work.

refspec: add and use refspec_appendf()

2020-09-06T20:15:46Z

Add a function for building a refspec using printf-style formatting. It frees callers from managing their own buffer. Use it throughout the tree to shorten and simplify its callers. Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano

refspec: fix documentation referring to refspec_item

2020-08-17T17:39:19Z

In commit d27eb356bf25 ("remote: move doc to remote.h and refspec.h") the documentation for the refspec structure was moved into refspec.h This documentation refers to elements of the refspec_item, not the struct refspec. Move the documentation slightly in order to align it with the structure it is actually referring to. Signed-off-by: Jacob Keller Signed-off-by: Junio C Hamano

argv-array: rename to strvec

2020-07-28T22:02:17Z

The name "argv-array" isn't very good, because it describes what the data type can be used for (program argument arrays), not what it actually is (a dynamically-growing string array that maintains a NULL-terminator invariant). This leads to people being hesitant to use it for other cases where it would actually be a good fit. The existing name is also clunky to use. It's overly long, and the name often leads to saying things like "argv.argv" (i.e., the field names overlap with variable names, since they're describing the use, not the type). Let's give it a more neutral name. I settled on "strvec" because "vector" is the name for a dynamic array type in many programming languages. "strarray" would work, too, but it's longer and a bit more awkward to say (and don't we all say these things in our mind as we type them?). A more extreme direction would be a generic data structure which stores a NULL-terminated of _any_ type. That would be easy to do with void pointers, but we'd lose some type safety for the existing cases. Plus it raises questions about memory allocation and ownership. So I limited myself here to changing names only, and not semantics. If we do find a use for that more generic data type, we could perhaps implement it at a lower level and then provide type-safe wrappers around it for strings. But that can come later. This patch does the minimum to convert the struct and function names in the header and implementation, leaving a few things for follow-on patches: - files retain their original names for now - struct field names are retained for now - there's a preprocessor compat layer that lets most users remain the same for now. The exception is headers which made a manual forward declaration of the struct. I've converted them (and their dependent function declarations) here.

remote: move doc to remote.h and refspec.h

2019-11-18T06:21:28Z

Move the documentation from Documentation/technical/api-remote.txt to remote.h and refspec.h as it's easier for the developers to find the usage information beside the code instead of looking for it in another doc file. N.B. The doc for both push and fetch members of the remote struct aren't moved because they are out of date, as the members were changed from arrays of rspecs to struct refspec 2 years ago. Also documentation/technical/api-remote.txt is removed because the information it has is now redundant and it'll be hard to keep it up to date and synchronized with the documentation in the header file.

refspec: add back a refspec_item_init() function

2018-06-11T17:11:31Z

Re-add the non-fatal version of refspec_item_init_or_die() renamed away in an earlier change to get a more minimal diff. This should be used by callers that have their own error handling. This new function could be marked "static" since nothing outside of refspec.c uses it, but expecting future use of it, let's make it available to other users.
