* grep: for -L, exitcode 0 means files *without* matches were found, closes 13151Denys Vlasenko2020-08-151-0/+8
| | | | | | | | | This is a recent change in GNU grep as well (after 3.1) function old new delta grep_file 1215 1228 +13 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* grep: add proper support for pattern_listSören Tempel2020-04-301-0/+12
| | | | | | | | | | | | | | | From POSIX.1-2008: The pattern_list's value shall consist of one or more patterns separated by <newline> characters; As such, given patterns need to be split at newline characters. Without doing so, busybox grep will interpret the newline as part of the pattern which is not in accordance with POSIX.

* grep: Fix -f FILE when FILE is empty and -x providedGray Wolf2020-04-291-0/+6
| | | | | | | | | | Grep currently special-cased empty pattern file to be the same as pattern file with one empty line (empty pattern). That does mirror how GNU grep behaves, except when -x is provided. In that case .* pattern needs to be used instead.

* grep: fix -x -v with certain pattern ordersAri Sundholm2019-01-291-0/+7
| | | | | | | | | | | | | | | | | | | | | | We found out that busybox -x -v is a bit broken: ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e 'aa.*' -e '.*bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e 'aa.*' -e '.*bb.*' ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -e '.*aa.*' -e 'bb.*' aa bb cc ari@ari-thinkpad:~/busybox$ echo ' aa bb cc' | ./busybox grep -x -v -e '.*aa.*' -e 'bb.*' aa bb cc Last one is wrong. This patch fixes the issue by making sure that the variable 'found' never makes a transition from 1 to 0, as this would mean that grep previously found a match on this input line.

| | | | | | | | | Unfortunately, with !EXTRA_COMPAT, "grep -w ^str" still erroneously matches "strstr". function old new delta grep_file 1499 1510 +11 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* grep: fix grep -x to not set REG_NOSUBJames Hogan2013-05-161-0/+14
| | | | | | | | | | | | | | | When -F isn't specified (and !ENABLE_EXTRA_COMPAT), grep -x uses regexec's regmatch_t output to determine if the match was the entire line. However it also set the REG_NOSUB flag which makes it ignore the regmatch_t argument. Add an exception to the setting of REG_NOSUB for OPT_x and add some test cases to test the behaviour of -x.

* Fix the test suite so that individual *.tests files can be run alaRob Landley2005-11-071-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | COMMAND=sort ./sort.tests So we can compare against non-busybox versions, and possibly our testsuite will be useful to somebody like the Linux Test Project someday. Redid testing.sh to add new command, "optional", to skip tests that require certain features. (use: `optional FEATURE_SORT_BIG`, or `optional ""` to stop skipping.) Note that optional is a NOP if the environment variable "OPTIONFLAGS" is blank, so although we're marking up the tests with busybox specific knowledge, it doesn't interfere with running the tests without busybox. Moved setting the "OPTIONFLAGS" environment variable to runtest. Philosophy: busybox-specific stuff belongs in runtest; both testing.sh and the tests themselves should be as busybox-agnostic as possible. Moved detecting that a command isn't in busybox at all (hence skipping the entire command.tests file) to runtests. Rationale: optional can't currently test for more than one feature at a time, so if we clear anything with optional "" we might perform tests we don't want to. Marked up busybox.tests to know which tests need CAT enabled. Fixed up other tests to be happy with new notation. I suspect egrep should be appended to grep. It's a sub-feature, really...

* - introduce variable _BB_CONFIG_DEP to the new test harness.Bernhard Reutner-Fischer2005-09-231-0/+82
This is used to see if given tests should be run (are available) or not. Print "UNTESTED: descr" if the applet or feature is not available. - add _BB_CONFIG_DEP to existing new.tests - move old grep test to new test infrastructure and add a few more test for grep.
