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_write_entry(): support files with holes

2011-05-21T06:16:53Z

One typical use of a large binary file is to hold a sparse on-disk hash table with a lot of holes. Help preserving the holes with lseek(). Signed-off-by: Junio C Hamano

streaming_write_entry(): use streaming API in write_entry()

2011-05-21T01:46:58Z

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: Junio C Hamano

write_entry(): separate two helper functions out

2011-05-21T01:38:54Z

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: Junio C Hamano

entry.c: remove "checkout-index" from error messages

2010-11-29T22:03:07Z

Back then when entry.c was part of checkout-index (or checkout-cache at that time [1]). It makes sense to print the command name in error messages. Nowadays entry.c is in libgit and can be used by any commands, printing "git checkout-index: blah" does no more than confusion. The error messages without it still give enough information.

ie_match_stat(): do not ignore skip-worktree bit with CE_MATCH_IGNORE_VALID

2009-12-14T22:03:58Z

Previously CE_MATCH_IGNORE_VALID flag is used by both valid and skip-worktree bits. While the two bits have similar behaviour, sharing this flag means "git update-index --really-refresh" will ignore skip-worktree while it should not. Instead another flag is introduced to ignore skip-worktree bit, CE_MATCH_IGNORE_VALID only applies to valid bit. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano
