3357 ----------------------
|

3358
|
|
3359 Some ``bugs'' may actually be no bugs at all. For instance, if you are
|
|
3360 reporting that certain difference regions are not matched as you think they
|
|
3361 should, this is most likely due to the way Unix diff program decides what
|
|
3362 constitutes a difference region. Ediff is an Emacs interface to diff, and
|
|
3363 it has nothing to do with those decisions---it only takes the output from
|
|
3364 diff and presents it in a way that is better suited for human browsing and
|
|
3365 manipulation.
|
|
3366
|
|
3367 If Emacs happens to dump core, this is NOT an Ediff problem---it is
|
|
3368 an Emacs bug. Report this to Emacs maintainers.
|
|
3369
|
|
3370 Another popular topic for reports is compilation messages. Because Ediff
|
|
3371 interfaces to several other packages and runs under Emacs and XEmacs,
|
|
3372 byte-compilation may produce output like this:
|
|
3373
|
|
3374 While compiling toplevel forms in file ediff.el:
|
|
3375 ** reference to free variable pm-color-alist
|
|
3376 ........................
|
|
3377 While compiling the end of the data:
|
|
3378 ** The following functions are not known to be defined:
|
|
3379 ediff-valid-color-p, ediff-set-face,
|
|
3380 ........................
|
|
3381
|
|
3382 These are NOT errors, but inevitable warnings, which ought to be ignored.
|
|
3383
|
|
3384 Please do not report those and similar things. However, comments and
|
|
3385 suggestions are always welcome.
