* sed: improve integer overflow checkingPaul Eggert2022-12-191-13/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix some some longstanding but unlikely integer overflows. Internally, 'sed' now more often prefers signed integer arithmetic, which can be checked automatically via 'gcc -fsanitize=undefined'. * basicdefs.h (countT): Remove. All uses replaced with a more-specific signed type, e.g., idx_t. Similarly, change uses of types like size_t to signed types like idx_t when appropriate. (REALLOC): Remove; no longer used. We now use xpalloc because that detects integer overflow in size calculations. Also, we no longer use XCALLOC since the code never relies on the storage being zero, and leaving it uninitialized is more likely to catch errors when debugging implementations are used. We use XNMALLOC instead, or xpalloc. * bootstrap.conf (gnulib_modules): Add stdckdint, strtoimax. * lib/.gitignore, m4/.gitignore: Update for new Gnulib modules. * sed/compile.c: Include stdckdint.h. (VECTOR_ALLOC_INCREMENT): Remove; no longer used. (in_integer): Return maximal value if integer overflow. All callers changed to expect this. (next_cmd_entry): Use xpalloc instead of reallocating by hand, which might suffer integer overflow. (normalize_text): Don’t rely on system-defined conversion of out-of-range size_t to int. (next_cmd_entry): Arg is now pointer, not pointer-to-pointer. All uses changed. * sed/debug.c (debug_print_function): Don’t attempt to fwrite a null pointer with a zero size. * sed/execute.c: Include <stdckdint.h>, "minmax.h". (resize_line): LEN arg is now increment, not total length, to avoid overflow when calculating total length. All uses changed. Do not assume lb->alloc * 2 cannot overflow. (resize_line, line_copy): Use xpalloc instead of doing realloc by hand, which might suffer integer overflow. (str_append_modified): Do not add n to to->length until after it's known this cannot overflow. (read_file_line): Don’t assume ssize_t fits in long. (get_backup_file_name): Don’t assume string length fits in int. Do not assume PTR-1+1 works; behavior is undefined if PTR is at buffer start. Check for integer overflow in buffer size calculation. (read_pattern_space): Check for line number overflow. (match_address_p): Check for address overflow. (debug_print_line): Omit unnecessary test for in->active being null. (execute_program): Check for Q overflow. * sed/regexp.c: Include <stdckdint.h>. (match_regex): Don’t assume TYPE_MAXIMUM (regoff_t) == INT_MAX. * sed/sed.c: Include inttypes.h, for strtoimax. (main): Use strtoimax, not atoi. * sed/utils.c (init_buffer): Use xmalloc and xpalloc instead of guessing sizes ourselves, and unnecessarily initializing. (resize_buffer): Remove; all callers changed to use xpalloc. (free_buffer): Don’t call free (NULL), since we already test whether the pointer is null.
* sed: simplify how diagnostics are translatedPaul Eggert2022-12-191-23/+4
| | | | | | | | | | | | | | | | | | | * basicdefs.h, sed/regexp.c (N_): Remove; no longer used. * bootstrap.conf (XGETTEXT_OPTIONS): Treat bad_prog as a function that translates its first arg. Omit unnecessary flags. * sed/compile.c, sed/regexp.c (errors): Remove this array of concatenated strings, and associated macros. All users of these macros now simply call bad_prog ("diagnostic") instead of bad_prog (_(DIAGNOSTIC_MACRO)). This is easier to read and maintain, and made it easy to catch two diagnostics that were never properly translated before: "cannot specify modifiers on empty regexp", "missing filename in r/R/w/W commands". * sed/compile.c (bad_command): Remove; no longer used. (vbad_prog): New function, with most of the old bad_prog contents. (bad_prog): Now variadic, like printf. Always translate WHY. All callers changed. (bad_prog_notranslate): New function.

* sed: fix memory leakAssaf Gordon2018-08-081-1/+13
| | | | | * sed/regexp.c (match_regex): Free the previously allocated regex struct before re-building the regex during program execution.
* sed: free allocated memory under lint, remove DEBUG_LEAKSAssaf Gordon2018-08-081-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Under normal operation there is no need for explicit freeing, as all memory will be released when sed terminates. During development (and specifically, valgrind and address-sanitizing) enabling lint prevents false-positive warnings about memory leaks. Lint mode can be enabled with CFLAGS="-Dlint". It is also automatically enabled by default when building from git (as opposed to tarball). For consistency all instances of "#ifdef DEBUG_LEAKS" are replaced with "#ifdef lint". * sed/sed.h (struct subst): Add member variable to keep the address of allocated buffer in compile.c:setup_replacement(). (release_regex): Add declaration. (finish_program): Function now takes an argument: the sed program vector. * sed/sed.c (main): Adjust call to finish_program. * sed/compile.c (finish_program): Release program allocations. (setup_replacement): Remember the allocated buffer address. (compile_program): Free temporary array in 'y' command. * sed/execute.c (execute_program): Free allocated but unused buffer in 'R' command when reaching EOF. * sed/regexp.c (release_regex): Remove 'static', free the allocated dfa struct. * sed/utils.c (panic): Free open files linked-list elements.

* sed: reject RE searches on buffers larger than INT_MAXAssaf Gordon2018-03-231-0/+5
| | | | | | | | | | | | | | | | | | | | Sed uses 'size_t' internally, but gnulib's re_search uses 'signed int'. If the buffer is larger than INT_MAX, reject it (panic, exit code 4). The test is marked 'very expensive' and skipped by default (due to creating a 2GB input file). To run it, use: make check SUBDIRS=.

* sed: enable special meaning of '+' with '-E --posix'Assaf Gordon2017-04-181-1/+3
| | | | | | | | | | | | | | in sed-4.2 and later, '--posix' option wrongly disabled the special meaning of '+' even in ERE mode (--posix should only disable it in BRE mode, since it is a GNU extension in BRE).

| | | | | | | | | * sed/regexp.c (compile_regex_1): Remove #ifdef RE_ICASE guard, since dfa.c uses it unconditionally. Suggested by Norihiro Tanaka. Also remove the nearby "#ifdef RE_NO_SUB". Those macros are guaranteed to be defined by virtue of configure-time tests that ensure we're using either a new-enough native glibc (RE_NO_SUB was added in 2004), or the included replacement.

* sed: fix multi-line regex matching with -zNorihiro Tanaka2016-11-041-6/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sed incorrectly matches the anchor '^' to a newline character (ASCII 10) despite using NUL line terminators (-z). See https://bugs.gnu.org/24615 . Previous (incorrect) behavior: $ printf "a\0b\0" | sed -z 'N;s/^/X/mg;' | od -An -a X a nul b nul With this fix: $ printf "a\0b\0" | sed -z 'N;s/^/X/mg;' | od -An -a X a nul X b nul Current regex engine can not handle NUL multiline anchors. Implement such search manually (by breaking the pattern into separate NUL-terminated lines) and searching each one individually. * NEWS: Mention it. * sed/regexp.c (compile_regex_1): Don't use newline_anchor of regex, if the buffer delimiter is not newline character.
