From ad76d58e7f1f26739255c22a69725c83eb47511a Mon Sep 17 00:00:00 2001 From: Ben Greear Date: Sun, 21 Mar 2010 23:24:36 +0100 Subject: Fix tftp return codes and tsize upload handling Error codes were not properly returned to the main curl code (and on to apps using libcurl). tftp was crapping out when tsize == 0 on upload, but I see no reason to fail to upload just because the remote file is zero-length. Ignore tsize option on upload. --- lib/tftp.c | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-) diff --git a/lib/tftp.c b/lib/tftp.c index cab6c09d4..dde17735a 100644 --- a/lib/tftp.c +++ b/lib/tftp.c @@ -398,12 +398,17 @@ static CURLcode tftp_parse_option_ack(tftp_state_data_t *state, long tsize = 0; tsize = strtol( value, NULL, 10 ); - if(!tsize) { - failf(data, "invalid tsize -:%s:- value in OACK packet", value); - return CURLE_TFTP_ILLEGAL; - } - Curl_pgrsSetDownloadSize(data, tsize); infof(data, "%s (%ld)\n", "tsize parsed from OACK", tsize); + + /* tsize should be ignored on upload: Who cares about the size of the + remote file? */ + if (!data->set.upload) { + if(!tsize) { + failf(data, "invalid tsize -:%s:- value in OACK packet", value); + return CURLE_TFTP_ILLEGAL; + } + Curl_pgrsSetDownloadSize(data, tsize); + } } } @@ -1471,8 +1476,11 @@ static CURLcode tftp_do(struct connectdata *conn, bool *done) code = tftp_perform(conn, done); - /* If we have encountered an error */ - code = tftp_translate_code(state->error); + /* If tftp_perform() returned an error, use that for return code.
