annotate arogue7/pack.c @ 176:db1c9a21a7c3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
srogue: prevent overflowing the score file name. If SCOREFILE is not defined, roguehome() is called to find a directory for the score file. It copies up to PATH_MAX-20 bytes from an environment variable to a static buffer. Later these are strcpy()'d to scorefile, which is of size LINLEN. Unfortunately LINLEN is 80 and PATH_MAX is at least 256. On Linux, it happens to be 4096. I haven't yet managed to crash or exploit it, but there are surely no beneficial consequences, so roguehome() has been modified to check the length, and the string it returns is also checked in main().
