Fix some bugs in fns.c, discovered in passing while doing other work.
2010-11-14 Aidan Kehoe <kehoea@parhasard.net>
* fns.c (Fnreverse):
Check that non-list sequences are writable from Lisp before
modifying them. (There's an argument that we should do this for
list sequences too, but for the moment other code (e.g. #'setcar)
doesn't.)
(mapcarX): Initialise lisp_vals_staging, lisp_vals_type
explicitly, for the sake of compile warnings. Check if
lisp_vals_staging is non-NULL when deciding whether to replace a
string's range.
(Fsome): Cross-reference to #'find-if in the doc string for this
function.
(Freduce): GCPRO accum in this function, when a key argument is
specicified it can be silently garbage-collected. When deciding
whether to iterate across a string, check whether the cursor
exceeds the byte len; while iterating, increment an integer
counter. Don't ABORT() if check_sequence_range() returns when
handed a suspicious sequence; it is legal to supply the length of
SEQUENCE as the :end keyword value, and this will provoke our
suspicions, legitimately enough. (Problems with this function
revealed by Paul Dietz' ANSI test suite, thank you Paul Dietz.)
(Freplace): Check list sequence lengths using the arguments, not
the conses we're currently looking at, thank you Paul Dietz.

/* Hey Emacs, this is -*- C -*- code! */ /* Synched up with: Not synched with FSF. */ /* Think twice before editing this file. Generated automatically by configure. The file startup.el guesses at reasonable values for load-path, exec-path, and lock-directory. This means that if you move emacs and its associated sub-tree to a different place in the filesystem, or to a different machine, you won't have to do anything for it to work. If you define the paths in this file then they will take precedence over any value generated by the heuristic in startup.el. The hardcoded paths will be checked to see if they are valid, in which case they will be used. Otherwise the editor will attempt to make its normal guess. See the NEWS file for a description of the heuristic used to locate the lisp and exec directories at startup time. If you are looking at this file because you are having trouble, then you would be much better off arranging for those heuristics to succeed than defining the paths in this file. ** Let me say that again. If you're editing this file, you're making ** a mistake. Re-read the section on installation in ../etc/NEWS. If it defines anything, this file should define some subset of the following: PATH_PREFIX The default value of `prefix-directory'. This is the default root for everything. PATH_LOADSEARCH The default value of `load-path'. PATH_EXEC The default value of `exec-directory' and `exec-path'. (exec-path also contains the value of whatever is in the PATH environment variable.) PATH_DATA The default value of `data-directory'. This is where architecture-independent files are searched for. PATH_LOCK The name of the directory that contains lock files with which we record what files are being modified in Emacs. This directory should be writable by everyone. If this is specified, the string must end with a slash! PATH_SUPERLOCK The name of the file !!!SuperLock!!! in the lock directory. You probably should let this default... PATH_INFO The default value of `Info-directory-list'. This is where info files are searched for. */
