For the +purposes of this Debian package, though, it is compiled as a shared +library. + +The word lists, *.txt in the source package, may be either + (a) compiled to a file zxcvbn.dict, or + (b) included in the object compiled from zxcvbn.c (in our case, in + libzxcvbn.so.*). +This choice is made by means of the USE_DICT_FILE compiler macro. + +Contrary to what you might expect, method (a) does not permit swapping +out zxcvbn.dict for a different file: CRCs for zxcvbn.dict are +compiled into the object compiled from zxcvbn.c (in our case, in +libzxcvbn.so.0). + +So method (a) is useless when zxcvbn-c is compiled as a shared +library. Further, it complicates usage: a library user must call +ZxcvbnInit() with the path to the immutable zxcvbn.dict, and later +ZxcvbnUninit(). + +Given the above facts about option (a), I have opted to use option (b) +for this Debian package. USE_DICT_FILE is unset. Calls to +ZxcvbnInit() and ZxcvbnUninit() are not required, and README.md has +been patched accordingly. + + -- Sean Whitton <spwhitton@spwhitton.name>, Sat, 24 Sep 2016 14:08:03 -0700 |
