2012-02-24teach convert_to_git a "dry run" modeJeff King
Some callers may want to know whether convert_to_git will actually do anything before performing the conversion itself (e.g., to decide whether to stream or handle blobs in-core). This patch lets callers specify the dry run mode by passing a NULL destination buffer. The return value, instead of indicating whether conversion happened, will indicate whether conversion would occur. For readability, we also include a wrapper function which makes it more obvious we are not actually performing the conversion. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2011-05-26stream filter: add "no more input" to the filtersJunio C Hamano
Some filters may need to buffer the input and look-ahead inside it to decide what to output, and they may consume more than zero bytes of input and still not produce any output. After feeding all the input, pass NULL as input as keep calling stream_filter() to let such filters know there is no more input coming, and it is time for them to produce the remaining output based on the buffered input.

2011-05-26Add streaming filter APIJunio C Hamano
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.

2011-05-26convert.h: move declarations for conversion from cache.hJunio C Hamano
Before adding the streaming filter API to the conversion layer, move the existing declarations related to the conversion to its own header file. Signed-off-by: Junio C Hamano <>
