* Send "Binary file FOO matches" to stderrPaul Eggert2020-09-171-3/+2
| | | | | | | | | | | * NEWS, doc/grep.texi: Mention this change (Bug#29668). * src/grep.c (grep): Send "Binary file FOO matches" to stderr instead of stdout. * tests/encoding-error, tests/invalid-multibyte-infloop: * tests/null-byte, tests/pcre-count, tests/surrogate-pair: * tests/symlink, tests/unibyte-binary: Adjust tests to match new behavior. In all cases this simplifies the tests, which is a good sign.
* Suppress "Binary file FOO matches" if -IPaul Eggert2020-09-171-0/+9
| | | | | | | Problem reported by Jason Franklin (Bug#33552). * NEWS: Mention this. * src/grep.c (grep): Do not output "Binary file FOO matches" if -I. * tests/encoding-error: Add test for this bug.
* maint: update all copyright year number rangesJim Meyering2020-01-011-1/+1
| | | | | | | | Run "make update-copyright" and then... * gnulib: Update to latest with copyright year adjusted. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * doc/grep.in.1: Use "-" in copyright year ranges, not \en.
* tests: work around AIX 7.2 sh printf bugPaul Eggert2019-12-251-3/+3
| | | | | | | | | | AIX 7.2 /bin/sh’s printf command mishandles octal escapes in multibyte locales: it treats them as characters, not bytes. * tests/backslash-s-vs-invalid-multitype, tests/encoding-error: Use the C locale when employing the printf command with an octal escape that AIX 7.2 sh might mishandle. * tests/init.sh (setup_): Use the C locale for tests. This has the side benefit of making them more reproducible.
* maint: update all copyright dates via "make update-copyright"Jim Meyering2019-01-011-1/+1
| | | | * gnulib: Also update submodule for its copyright updates.
* maint: update gnulib and copyright dates for 2018Jim Meyering2018-01-061-1/+1
| | | | | | * gnulib: Update to latest. * all files: Run "make update-copyright". * bootstrap: Update from gnulib.
* maint: update gnulib and copyright dates for 2017Jim Meyering2017-01-011-1/+1
| | | | | * gnulib: Update to latest. * all files: Run "make update-copyright".
* tests: use "returns_" rather than explicit comparison with "$?"Jim Meyering2016-11-141-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | * tests/sjis-mb (encode): Rearrange to emit desired input into a file, rather than piping directly into grep. That permits the use of returns_ 1 to verify timeout's exit status. * tests/euc-mb: Use "returns_ 1" rather than testing $? = 1 * tests/char-class-multibyte: Likewise. * tests/dfa-heap-overrun: Likewise. * tests/encoding-error: Likewise. * tests/fedora: Likewise. * tests/grep-dev-null: Likewise. * tests/init.cfg (envvar_check_fail): Likewise. * tests/kwset-abuse: Likewise. * tests/mb-non-UTF8-overrun: Likewise. * tests/multibyte-white-space: Likewise. * tests/pcre-infloop: Likewise. * tests/surrogate-pair: Likewise. * tests/warn-char-classes: Likewise. Do the same for other values: * tests/backref-multibyte-slow: Likewise. * tests/euc-mb: Likewise. * tests/pcre-abort: Likewise. * tests/pcre-jitstack: Likewise. * tests/repetition-overflow: Likewise. * tests/reversed-range-endpoints: Likewise. * tests/warn-char-classes: Likewise.
* grep: encoding errors suppress just their linePaul Eggert2016-09-081-0/+4
| | | | | | | | From a suggestion by Marcello Perathoner (Bug#22838). * NEWS, doc/grep.texi (File and Directory Selection): Document this. * src/grep.c (print_line_head): Do not suppress later output lines merely because an earlier output line would have had an encoding error. * tests/encoding-error: Test for the new behavior.
* tests: fix encoding-error test failure to use of printf '\xHH'Jim Meyering2016-01-081-1/+1
| | | | | | | * tests/encoding-error: Don't rely on printf having support for \xHH hexadecimal. That is not portable. Use \OOO octal, instead. maint: fix typo in NEWS: s/a/an/
* maint: update copyright year, bootstrap, init.shJim Meyering2016-01-011-1/+1
| | | | | | | | Run "make update-copyright" and then... * gnulib: Update to latest. * tests/init.sh: Update from gnulib. * bootstrap: Likewise.
* grep: be less picky about encoding errorsPaul Eggert2015-12-301-0/+41
This fixes a longstanding problem introduced in grep 2.21, which is overly picky about binary files. * NEWS: * doc/grep.texi (File and Directory Selection): Document this. * src/grep.c (input_textbin, textbin_is_binary, buffer_textbin) (file_textbin): Remove. All uses removed. (encoding_error_output): New static var. (buf_has_encoding_errors, buf_has_nulls, file_must_have_nulls): New functions, which reuse bits and pieces of the removed functions. (lastout, print_line_head, print_line_middle, print_line_tail, prline) (prpending, prtext, grepbuf): Avoid use of const, now that we have functions that require modifying a sentinel. (print_line_head): New arg LEN. All uses changed. (print_line_head, print_line_tail): Return indicator whether the output line was printed. All uses changed. (print_line_middle): Exit early on encoding error. (grep): Use new method for determining whether file is binary. * src/grep.h (enum textbin, TEXTBIN_BINARY, TEXTBIN_UNKNOWN) (TEXTBIN_TEXT, input_textbin): Remove decls. All uses removed. * src/pcresearch.c (Pexecute): Remove multiline optimization, since the main program no longer checks for encoding errors on input. * tests/encoding-error: New file. * tests/Makefile.am (TESTS): Add it.
