Subject: http_recv: Fix reading of the HTTP OK message pattern.
X-Git-Tag: v0.3.3~27
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=7ddeb416451e763677f1638263e26e0855d79d91;hp=8f3685d67bcec78c7028eedc9ee0fcaefb3aa13f

http_recv: Fix reading of the HTTP OK message pattern.

This bug leads to sound artefacts at the beginning of the
stream caused by calling recv_pattern() with a buffer size
larger than the HTTP OK message.

It may thus happen that the buffer used by recv_pattern() contains
not only the HTTP OK message but also the beginning of the stream.
Since that buffer is discarded by recv_pattern(), the first few
bytes of the stream are lost if this happens.

Fix it by passing the exact length of the HTTP OK message to
recv_pattern().
