From a report from + John Kearney + + 2/21 ---- -parse.y - - fix report_syntax_error to set last_command_exit_value to - EX_BADUSAGE (2) instead of EX_USAGE (258), since there's nothing - that will translate that to something < 128 before reading the - next command. Partial fix for bug reported by Mike Frysinger - +doc/{bash,builtins}.1 + - minor changes from Bjarni Ingi Gislason -sig.c - - fix sigint_sighandler to set last_command_exit_value to sig+128 - before calling throw_to_top_level.

Bug and fix from Doug Kehn + + 2/25 + ---- +error.c + - report_error: make sure last_command_exit_value is non-zero before + we call exit_shell, since the exit trap may reference it.

Johnson +lib/readline/complete.c + - print_filename: if there is no directory hook, but there is a stat + hook, and we want to append a slash to directories, call the stat + hook before calling path_isdir on the expanded directory name. + Report and pointer to fix from Steve Rago 3/3 --- -parse.y - - break comment checking code into a common COMMENT_BEGIN define so - we can use it in multiple places in parse_comsub - - in parse_comsub, don't alter the LEX_RESWDOK flag if we read a - `#' and we're checking comments, even though `#' isn't a `shell break' - character. Fixes bug reported by Mike Frysinger +builtins/evalstring.c + - parse_and_execute: fix to change of 2/18: make sure the file + descriptor being redirected to is 0 before calling cat_file when + we see something like $(< file). Real fix for bug reported by + Dan Douglas -braces.c - - in expand_seqterm, decrease the total length of the rhs by the length - of any (optional) increment, so we don't end up with unwanted zero - padding because the rhs length is wrong. Fixes bug reported by - Carl Albing +subst.c + - parameter_brace_patsub: run the replacement string through quote + removal even if the expansion is within double quotes, because + the parser and string extract functions treat the quotes and + backslashes as special. If they're treated as special, quote + removal should remove them (this is the Posix position and + compatible with ksh93). THIS IS NOT BACKWARDS COMPATIBLE. 3/4 --- -doc/{bash.1,bashref.texi} - - changes to clean up some of the language describing the effects of - terminal process groups on the ability to read from and write to - the terminal +lib/readline/complete.c + - rl_menu_complete: fix to make show-all-if-ambiguous and + menu-complete-display-prefix work together if both are set.

Fix from - Timothy Redaelli - -parse.y - - in parse_comsub, allow comments if we are ready to read a - reserved word (tflags & LEX_RESWDOK), haven't read anything from - one yet (lex_rwlen == 0) and the current character is a '#' - - 3/6 - --- -parse.y - - new lex flag for parse_comsub: LEX_INWORD. Turn it off when - we see a shell break character; turn it on or keep it on when - not a break character. Keep track of word length (reset to 0 - when we turn on LEX_INWORD when it was off). - - don't use COMMENT_BEGIN in parse_comsub any more; test - whether or not LEX_INWORD is set and lex_wlen == 0 in addition - to tests for LEX_RESWDOK and lex_rwlen. Comments are valid - when at the start of a word - - move LEX_PASSNEXT code to the top of parse_comsub, so the rest - of the function doesn't have to check for the flag at different - places +bashline.c + - dircomplete_expand_relpath: new variable, if non-zero, means that + `shopt -s direxpand' should expand relative pathnames. Zero by + default, not user-settable yet + - bash_directory_completion_hook: if we have a relative pathname that + isn't changed by canonicalization or spell checking after being + appended to $PWD, then don't change what the user typed. Controlled + by dircomplete_expand_relpath 3/7 --- -parse.y - - in parse_comsub, when looking for a reserved word (LEX_RESWDOK - non-zero), and in a case statement, we can see either an esac - or a pattern list. We handle an esac separately. We should - turn off LEX_RESWDOK if we see anything but a newline, since - we'll be reading a pattern list. Other part of fix for bug - reported by Mike Frysinger (rest of fix - on 3/3) +m4/timespec.m4 + - new macros, cribbed from gnulib and coreutils: find out whether we + have `struct timespec' and what file includes it + +m4/stat-time.m4 + - new macros, cribbed from gnulib and coreutils: find out whether the + mtime/atime/ctime/etctime fields of struct stat are of type + struct timespec, and what the name is + +include/stat-time.h + - new file, cribbed from gnulib, with additions from coreutils: include + the right file to get the struct timespec define, or provide our own + replacement.

Fixes - Debian bug 519165 from Dan Jacobson +trap.c + - queue_sigchld_trap: new function, increments the number of pending + SIGCHLD signals by the argument, which is by convention the number + of children reaped in a call to waitchld() -parse.y - - add code to parse_comsub to allow here-documents within command - substitutions to be delimited by the closing right paren, with the - usual warning about here documents delimited by EOF on execution. - Fixes regression from bash-3.2 noted in Red Hat bugzilla 485664 by - Ralf Corsepius +trap.h + - queue_sigchld_trap: new extern declaration - 3/15 +jobs.c + - waitchld: if called from the SIGCHLD signal handler (sigchld > 0), + then call queue_sigchld_trap to avoid running the trap in a signal + handler context.
