3310 Some ``bugs'' may actually be no bugs at all. For instance, if you are
|
|
|
3311 reporting that certain difference regions are not matched as you think they
|
|
|
3312 should, this is most likely due to the way Unix diff program decides what
|
|
|
3313 constitutes a difference region. Ediff is an Emacs interface to diff, and
|
|
|
3314 it has nothing to do with those decisions---it only takes the output from
|
|
|
3315 diff and presents it in a way that is better suited for human browsing and
|
|
|
3316 manipulation.
|
|
|
3317
|
|
|
3318 If Emacs happens to dump core, this is NOT an Ediff problem---it is
|
|
|
3319 an Emacs bug. Report this to Emacs maintainers.
|
|
|
3320
|
|
|
3321 Another popular topic for reports is compilation messages. Because Ediff
|
|
|
3322 interfaces to several other packages and runs under Emacs and XEmacs,
|
|
|
3323 byte-compilation may produce output like this:
|
|
|
3324
|
|
|
3325 While compiling toplevel forms in file ediff.el:
|
|
|
3326 ** reference to free variable pm-color-alist
|
|
|
3327 ........................
|
|
|
3328 While compiling the end of the data:
|
|
|
3329 ** The following functions are not known to be defined:
|
|
|
3330 ediff-valid-color-p, ediff-set-face,
|
|
|
3331 ........................
|
|
|
3332
|
|
|
3333 These are NOT errors, but inevitable warnings, which ought to be ignored.
|
|
|
3334
|
|
|
3335 Please do not report those and similar things. However, comments and
|
|

3336 suggestions are always welcome.
