"0" however is a special value for "end of file" or "error". This patch makes input_curl_read() read more data from the socket, until the read request can be fulfilled (or until there's really EOF). --- src/input/curl_input_plugin.c | 42 ++++++++++++++++++++++-------------------- 1 file changed, 22 insertions(+), 20 deletions(-) (limited to 'src') diff --git a/src/input/curl_input_plugin.c b/src/input/curl_input_plugin.c index 4ed8e5b5b..b83bcd918 100644 --- a/src/input/curl_input_plugin.c +++ b/src/input/curl_input_plugin.c @@ -443,31 +443,33 @@ input_curl_read(struct input_stream *is, void *ptr, size_t size) } #endif - /* fill the buffer */ + do { + /* fill the buffer */ - success = fill_buffer(is); - if (!success) - return 0; + success = fill_buffer(is); + if (!success) + return 0; - /* send buffer contents */ + /* send buffer contents */ - if (c->rewind != NULL && - (!g_queue_is_empty(c->rewind) || is->offset == 0)) - /* at the beginning or already writing the rewind - buffer list */ - rewind_buffers = c->rewind; - else - /* we don't need the rewind buffers anymore */ - rewind_buffers = NULL; + if (c->rewind != NULL && + (!g_queue_is_empty(c->rewind) || is->offset == 0)) + /* at the beginning or already writing the rewind + buffer list */ + rewind_buffers = c->rewind; + else + /* we don't need the rewind buffers anymore */ + rewind_buffers = NULL; - while (size > 0 && !g_queue_is_empty(c->buffers)) { - size_t copy = read_from_buffer(&c->icy_metadata, c->buffers, - dest + nbytes, size, - rewind_buffers); + while (size > 0 && !g_queue_is_empty(c->buffers)) { + size_t copy = read_from_buffer(&c->icy_metadata, c->buffers, + dest + nbytes, size, + rewind_buffers); - nbytes += copy; - size -= copy; - } + nbytes += copy; + size -= copy; + } + } while (nbytes == 0); if (icy_defined(&c->icy_metadata)) copy_icy_tag(c); -- cgit v1.2.3 From a1d868eb56bab5063f367e392624e3b3de5ea4d3 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sun, 11 Oct 2009 23:14:16 +0200 Subject: decoder_thread: change the fallback decoder name to "mad" When there is no Content-Type response header, try the "mad" decoder plugin.
