* don't use xmalloc/xrealloc, but return -1 in case of memory allocation
failure
* modify the parameters only when allocation succeeds
|
|
* those functions expect an int whose value is between -1 and 255.
Cast to unsigned char so that sign extension when promoting to int
doesn't bite us.

* They are a c99 feature, which makes it impossible to build ratpoison
on some platforms. GCC supports zero-sized arrays, more conservative
approaches say to use foo[1], but as brlink says a compiler with
aggressive optimization turned on might play nasty tricks.
Just use a traditional struct.

If historysize is 0, do not create .ratpoison_history at exit
and do keep no entries in history. (Previously ratpoison would
always at least store the last entry).

found and compile without history support.
* src/ratpoison.h: change ifdef to check for HAVE_HISTORY.
* src/manage.c (get_state): change data to an unsigned char and
cast data to a long* when it's used.

Conditionalize libhistory checks accordingly.
* README: Mention "--disable history".
* src/history.c: Surround most of the code with
"#ifdef HAVE_READLINE_HISTORY_H".
* src/ratpoison.h: Only #include history.h when
"#ifdef HAVE_READLINE_HISTORY_H".
* src/main.c (main, clean_up): Only load and save history,
respectively, when "#ifdef HAVE_READLINE_HISTORY_H".
* src/editor.c (editor_history_previous, editor_history_next):
Return EDIT_NO_OP when not "#ifdef HAVE_READLINE_HISTORY_H".
(editor_enter): Do not do line expansion or history add
when not "#ifdef HAVE_READLINE_HISTORY_H".
* doc/ratpoison.texi: Mention that history cycling and
processing is not available when ratpoison is configured
with the "--disable-history" option.
