3182 ----------------------
|

3183
|
|
|
3184 Some ``bugs'' may actually be no bugs at all. For instance, if you are
|
|
|
3185 reporting that certain difference regions are not matched as you think they
|
|
|
3186 should, this is most likely due to the way Unix diff program decides what
|
|
|
3187 constitutes a difference region. Ediff is an Emacs interface to diff, and
|
|
|
3188 it has nothing to do with those decisions---it only takes the output from
|
|
|
3189 diff and presents it in a way that is better suited for human browsing and
|
|
|
3190 manipulation.
|
|
|
3191
|
|
|
3192 If Emacs happens to dump core, this is NOT an Ediff problem---it is
|
|
|
3193 an Emacs bug. Report this to Emacs maintainers.
|
|
|
3194
|
|
|
3195 Another popular topic for reports is compilation messages. Because Ediff
|
|
|
3196 interfaces to several other packages and runs under Emacs and XEmacs,
|
|
|
3197 byte-compilation may produce output like this:
|
|
|
3198
|
|
|
3199 While compiling toplevel forms in file ediff.el:
|
|
|
3200 ** reference to free variable pm-color-alist
|
|
|
3201 ........................
|
|
|
3202 While compiling the end of the data:
|
|
|
3203 ** The following functions are not known to be defined:
|
|
|
3204 ediff-valid-color-p, ediff-set-face,
|
|
|
3205 ........................
|
|
|
3206
|
|
|
3207 These are NOT errors, but inevitable warnings, which ought to be ignored.
|
|
|
3208
|
|
|
3209 Please do not report those and similar things. However, comments and
|
|
|
3210 suggestions are always welcome.
