When the output to a path does not have to be converted, we can read from the object database from the streaming API and write to the file in the working tree, without having to hold everything in the memory. The ident, auto- and safe- crlf conversions inherently require you to read the whole thing before deciding what to do, so while it is technically possible to support them by using a buffer of an unbound size or rewinding and reading the stream twice, it is less practical than the traditional "read the whole thing in core and convert" approach. Adding streaming filters for the other conversions on top of this should be doable by tweaking the can_bypass_conversion() function (it should be renamed to can_filter_stream() when it happens). Then the streaming API can be extended to wrap the git_istream streaming_write_entry() opens on the underlying object in another git_istream that reads from it, filters what is read, and let the streaming_write_entry() read the filtered result. But that is outside the scope of this series. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

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().

In the write-out codepath, a block of code determines what file in the working tree to write to, and opens an output file descriptor to it. After writing the contents out to the file, another block of code runs fstat() on the file descriptor when appropriate. Separate these blocks out to open_output_fd() and fstat_output() helper functions. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

An object found in the delta-base cache is not guaranteed to stay there, but we know it came from a pack and it is likely to give us a quick access if we read_sha1_file() it right now, which is a piece of useful information. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The original interface for sha1_object_info() takes an object name and gives back a type and its size (the latter is given only when it was asked). The new interface wraps its implementation and exposes a bit more pieces of information that the interface used to discard, namely: - where the object is stored (loose? cached? packed?) - if packed, where in which packfile? Signed-off-by: NJunio C Hamano <gitster@pobox.com> --- * In the earlier round, this used u.pack.delta to record the length of the delta chain, but the caller is not necessarily interested in the length of the delta chain per-se, but may only want to know if it is a delta against another object or is stored as a deflated data. Calling packed_object_info_detail() involves walking the reverse index chain to compute the store size of the object and is unnecessarily expensive. We could resurrect the code if a new caller wants to know, but I doubt it.

The way "object replacement" mechanism was tucked to the read_sha1_file() interface was suboptimal in a couple of ways: - Callers that want it to die with useful diagnosis upon seeing a corrupt object does not have a way to say that they do not want any object replacement. - Callers who do not want it to die but want to handle the errors themselves are told to arrange to call read_object(), but the function does not use the replacement mechanism, and also it is a file scope static function that not many callers can call to begin with. This adds a read_sha1_file_extended() that takes a set of flags; the callers of read_sha1_file() passes a flag READ_SHA1_FILE_REPLACE to ask for object replacement mechanism to kick in. Later, we could add another flag bit to tell the function to return an error instead of dying and then remove the misguided "call read_object() yourself".

In a repository without object replacement, lookup_replace_object() should be a no-op. Check the flag "read_replace_refs" on the side of the caller, and bypess a function call when we know we are not dealing with replacement. Also, even when we are set up to replace objects, if we do not find any replacement defined, flip that flag off to avoid function call overhead for all the later object accesses. As this change the semantics of the flag from "do we need read the replacement definition?" to "do we need to check with the lookup table?" the flag needs to be renamed later to something saner, e.g. "use_replace", when the codebase is calmer, but not now.

Most callers want to silently get a replacement object, and they do not care what the real name of the replacement object is. Worse yet, no sane interface to return the underlying object without replacement is provided. Remove the function and make only the few callers that want the name of the replacement object find it themselves. Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When adding a new content to the repository, we have always slurped the blob in its entirety in-core first, and computed the object name and compressed it into a loose object file. Handling large binary files (e.g. video and audio asset for games) has been problematic because of this design. At the middle level of "git add" callchain is an internal API index_fd() that takes an open file descriptor to read from the working tree file being added with its size. Teach it to call out to fast-import when adding a large blob. The write-out codepath in entry.c::write_entry() should be taught to stream, instead of reading everything in core. This should not be so hard to implement, especially if we limit ourselves only to loose object files and non-delta representation in packfiles. Signed-off-by: NJunio C Hamano <gitster@pobox.com>
