treewide: remove unnecessary cache.h inclusion from a few headers

2023-03-21T17:56:50Z

Ever since a64215b6cd ("object.h: stop depending on cache.h; make cache.h depend on object.h", 2023-02-24), we have a few headers that could have replaced their include of cache.h with an include of object.h. Make that change now. Some C files had to start including cache.h after this change (or some smaller header it had brought in), because the C files were depending on things from cache.h but were only formerly implicitly getting cache.h through one of these headers being modified in this patch.

streaming: allow open_istream() to handle any repo

2020-01-31T18:45:39Z

Some callers of open_istream() at archive-tar.c and archive-zip.c are capable of working on arbitrary repositories but the repo struct is not passed down to open_istream(), which uses the_repository internally. For now, that's not a problem since the said callers are only being called with the_repository. But to be consistent and avoid future problems, let's allow open_istream() to receive a struct repository and use that instead of the_repository. This parameter addition will also be used in a future patch to make sha1-file.c:check_object_signature() be able to work on arbitrary repos.

*.[ch]: remove extern from function declarations using spatch

2019-05-05T06:20:06Z

There has been a push to remove extern from function declarations. Remove some instances of "extern" for function declarations which are caught by Coccinelle. Note that Coccinelle has some difficulty with processing functions with `__attribute__` or varargs so some `extern` declarations are left behind to be dealt with in a future patch. This was the Coccinelle patch used: @@ type T; identifier f; @@ - extern T f(...); and it was run with: $ git ls-files \*.{c,h} | grep -v ^compat/ | xargs spatch --sp-file contrib/coccinelle/noextern.cocci --in-place Files under `compat/` are intentionally excluded as some are directly copied from external sources and we should avoid churning them as much as possible.

streaming: make stream_blob_to_fd take struct object_id

2016-09-07T19:59:42Z

Since all of its callers have been updated, modify stream_blob_to_fd to take a struct object_id. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

streaming: void pointer instead of char pointer

2012-05-03T17:22:56Z

Allow any kind of buffer to be fed to read_istream() without an explicit cast by making it's buf argument a void pointer. It's about arbitrary data, not only characters. Signed-off-by: Rene Scharfe Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

streaming: make streaming-write-entry to be more reusable

2012-03-07T17:07:37Z

The static function in entry.c takes a cache entry and streams its blob contents to a file in the working tree. Refactor the logic to a new API function stream_blob_to_fd() that takes an object name and an open file descriptor, so that it can be reused by other callers.

Add streaming filter API

2011-05-26T23:47:15Z

This introduces an API to plug custom filters to an input stream. The caller gets get_stream_filter("path") to obtain an appropriate filter for the path, and then uses it when opening an input stream via open_istream(). After that, the caller can read from the stream with read_istream(), and close it with close_istream(), just like an unfiltered stream. This only adds a "null" filter that is a pass-thru filter, but later changes can add LF-to-CRLF and other filters, and the callers of the streaming API do not have to change.

streaming: a new API to read from the object store

2011-05-21T01:46:55Z

Given an object name, use open_istream() to get a git_istream handle that you can read_istream() from as if you are using read(2) to read the contents of the object, and close it with close_istream() when you are done. Currently, we do not do anything fancy--it just calls read_sha1_file() and keeps the contents in memory as a whole, and carve it out as you request with read_istream(). Signed-off-by: Junio C Hamano
