Might cause write head running over read head, when there were no
allocation and `Commit()` was called. Source of at least one test
failure on windows (`simple/test-https-drain.js`).
// Go to next buffer if there still are some bytes to write
if (left != 0) {
+ assert(write_head_->write_pos_ == kBufferLength);
TryAllocateForWrite();
write_head_ = write_head_->next_;
}
// Allocate new buffer if write head is full,
// and there're no other place to go
TryAllocateForWrite();
- write_head_ = write_head_->next_;
+ if (write_head_->write_pos_ == kBufferLength)
+ write_head_ = write_head_->next_;
}
