http: work around custom http client classes that refuse extra attrs
I have no idea what is going on with our custom http client code at Google,
but it chokes on these extra attributes we're tucking on http clients. Since
it feels more than a little wrong to just stuff extra data on a client, let's
degrade gracefully when the client class refuses the attributes.
#ifndef _HG_BDIFF_H_
#define _HG_BDIFF_H_
#include "compat.h"
struct bdiff_line {
int hash, n, e;
ssize_t len;
const char *l;
};
struct bdiff_hunk;
struct bdiff_hunk {
int a1, a2, b1, b2;
struct bdiff_hunk *next;
};
int bdiff_splitlines(const char *a, ssize_t len, struct bdiff_line **lr);
int bdiff_diff(struct bdiff_line *a, int an, struct bdiff_line *b, int bn,
struct bdiff_hunk *base);
void bdiff_freehunks(struct bdiff_hunk *l);
#endif
