The mess created in compile.c + allowed a little simplification to the command-line + processing of "-e" options in sed.c. + + sed.h: added (opaque) err_info member to struct vector; + added comments to the members of struct vector. + +Wed Apr 14 23:50:50 PDT 1998 Ken Pizzini <ken@gnu.org> + + * sed.h, sed.c, compile.c, execute.c: added types countT and + flagT in order to clarify what various "int"s were doing. + Also makes it easy to change the type used for counts + (for example, to "unsigned long long") if desired, although + there are still some gotchas (such as the printf() format + for the '=' command). + +Tue Apr 14 17:34:54 PDT 1998 Ken Pizzini <ken@gnu.org> + + * execute.c (execute_program, process_files, count_branches, + shrink_program): Added a first attempt at program optimization. + We now can quit early if we are running with the "-n" + and all of the commands are known to be valid only for + lines less than the current line. Thus the "sed" in + "foo | sed -n 1,2p" will print read three lines, printint + the first two, and then quit, regardless of how much longer + "foo" might run or output. This optimization does not buy + much in most cases (it sometimes even costs a little), + but when it does help it can help big. The code is + all conditionally compiled based on the + EXPERIMENTAL_DASH_N_OPTIMIZATION symbol being #defined, + so it can be easily omitted if it causes problems. + +Tue Apr 14 12:25:06 PDT 1998 Ken Pizzini <ken@gnu.org> + + * execute.c (test_dollar_EOF, last_file_with_data_p): + test_dollar_EOF() was incorrectly returning a false (0) + when there were unprocessed files, none of which had any + data (either unopenable or zero-length). Created + last_file_with_data_p() to detect this situation, and + modified test_dollar_EOF() to make use of it. + +Thu Apr 2 23:02:18 PST 1998 Ken Pizzini <ken@gnu.org> + + * compile.c (match_slash): match_slash() did not handle + [.coll.], [=equiv=], and [:class:] sequences within a + character class. Added snarf_char_class() [which is a + remote derivative of parse_char_class() from GNU ed-0.2] + to deal with the details, and altered match_slash() + to make use of it. Also created the trivial + add_then_next() to avoid clutter in snarf_char_class(). + +Thu Apr 2 20:34:42 PST 1998 Ken Pizzini <ken@gnu.org> + + * execute.c, sed.c, sed.h: There was a severe bug in + how the code handled "sed 5n a b" when "a" consists + of exactly five lines -- it behaved like "sed 5q a b"! + + Rearranged where files get opened -- large scale + changes primarily involving main(), process_files(), + and read_pattern_space(), but also touching on several + other parts of execute.c. The read_pattern_space() + function became unwieldly and parts were split into + open_next_file(), closedown(), read_always_fail(), + read_mem_line(), and read_file_line(). The + at_end_of_file_p() function became obsolete and was + eliminated; test_dollar_EOF_p() was updated. A few + global and module-static variables were elminated, and + "struct line" was extended; comments were added to the + "struct line" declartation to document some important + dependencies in it. + + I undertook the reorganization with dread, but I + feel that the new organization is an improvement + well beyond just fixing the bug that inspired it. + +Thu Apr 2 01:16:25 PST 1998 Ken Pizzini <ken@gnu.org> + + * execute.c (read_file_line, slow_getline): the fread() + buffering code gives insufficient feedback to a user + running sed with a tty input device, so I created + slow_getline() for reading from a tty device. + Additionally, EOF detection has been made a little more + sensitive to avoid requiring multiple EOFs to be entered + from a tty. + + * configure.in: added isatty() check. + +Wed Apr 1 11:04:30 PST 1998 Ken Pizzini <ken@gnu.org> + + * configure.in (CPPFLAGS, LDFLAGS, LIBS): + Set to appropriate values if large file support needs + explicit enabling.

Thus the addition of + POSIXLY_CORRECT behavior. + + * execute.c: however, when seding multiple files my feeling + is that it makes sense to have each file but the last + behave as-if it ended in a newline.
