commandserver: drop tell() and seek() from channels (issue5049) These operations are obviously invalid for file-like channels because they will read or write protocol headers. This patch works around the issue that "hg archive" generates a corrupted zip file on Windows commandserver because of unusable tell() implementation. But the problem still occurs without using a commandserver. $ hg archive -R not-small-repo -t zip - | cat > invalid.zip So, this patch cannot fix the issue5049 completely.
