Carlos Martín Nieto 35e68606 2015-11-04T10:36:50 blob: fix fromchunks iteration counter By returning when the count goes to zero rather than below it, setting `howmany` to 7 in fact writes out the string 6 times. Correct the termination condition to write out the string the amount of times we specify.
Carlos Martín Nieto 0a5c6028 2015-11-04T10:30:48 blob: introduce creating a blob by writing into a stream The pair of `git_blob_create_frombuffer()` and `git_blob_create_frombuffer_commit()` is meant to replace `git_blob_create_fromchunks()` by providing a way for a user to write a new blob when they want filtering or they do not know the size. This approach allows the caller to retain control over when to add data to this buffer and a more natural fit into higher-level language's own stream abstractions instead of having to handle IO wait in the callback. The in-memory buffer size of 2MB is chosen somewhat arbitrarily to be a round multiple of usual page sizes and a value where most blobs seem likely to be either going to be way below or way over that size. It's also a round number of pages. This implementation re-uses the helper we have from `_fromchunks()` so we end up writing everything to disk, but hopefully more efficiently than with a default filebuf. A later optimisation can be to avoid writing the in-memory contents to disk, with some extra complexity.
