Log: patch(1): add some basic tests Summary: - basic: test application of patches created by diff -u at the beginning/middle/end of file, which have differing amounts of context before and after chunks being added - limited_ctx: stems from PR 74127 in which a rogue line was getting added when the patch should have been rejected. Similar behavior was reproducible with larger contexts near the beginning/end of a file. See r326084 for details - file_creation: patch sourced from /dev/null should create the file - file_nodupe: said patch sourced from /dev/null shouldn't dupe the contents when re-applied (personal vendetta, WIP, see comment) - file_removal: this follows from nodupe; the reverse of a patch sourced from /dev/null is most naturally deleting the file, as is expected based on GNU patch behavior (WIP) Added: head/usr.bin/patch/tests/ head/usr.bin/patch/tests/Makefile (contents, props changed) head/usr.bin/patch/tests/PR74127-cline.diff (contents, props changed) head/usr.bin/patch/tests/PR74127-good.diff (contents, props changed) head/usr.bin/patch/tests/PR74127-repro.diff (contents, props changed) head/usr.bin/patch/tests/PR74127.in (contents, props changed) head/usr.bin/patch/tests/unified_patch_test.sh (contents, props changed) Modified: head/etc/mtree/BSD.tests.dist head/usr.bin/patch/Makefile Modified: head/etc/mtree/BSD.tests.dist ============================================================================== --- head/etc/mtree/BSD.tests.dist Thu Sep 5 00:56:37 2019 (r351835) +++ head/etc/mtree/BSD.tests.dist Thu Sep 5 03:16:14 2019 (r351836) @@ -1018,6 +1018,8 @@ .. opensm .. + patch + .. pr .. printf Modified: head/usr.bin/patch/Makefile ============================================================================== --- head/usr.bin/patch/Makefile Thu Sep 5 00:56:37 2019 (r351835) +++ head/usr.bin/patch/Makefile Thu Sep 5 03:16:14 2019 (r351836) @@ -1,8 +1,13 @@ # $OpenBSD: Makefile,v 1.4 2005/05/16 15:22:46 espie Exp $ # $FreeBSD$ +.include <src.opts.mk> + PROG= patch SRCS= backupfile.c inp.c mkpath.c patch.c pch.c util.c + +HAS_TESTS= +SUBDIR.${MK_TESTS}+= tests .include <bsd.prog.mk> Added: head/usr.bin/patch/tests/Makefile ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/usr.bin/patch/tests/Makefile Thu Sep 5 03:16:14 2019 (r351836) @@ -0,0 +1,12 @@ +# $FreeBSD$ + +PACKAGE= tests + +ATF_TESTS_SH+= unified_patch_test + +${PACKAGE}FILES+= PR74127-cline.diff +${PACKAGE}FILES+= PR74127-good.diff +${PACKAGE}FILES+= PR74127-repro.diff +${PACKAGE}FILES+= PR74127.in + +.include <bsd.test.mk> Added: head/usr.bin/patch/tests/PR74127-cline.diff ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/usr.bin/patch/tests/PR74127-cline.diff Thu Sep 5 03:16:14 2019 (r351836) @@ -0,0 +1,4 @@ +file.c +@@ -3,1 +3,1 @@ +- set Log(compressProg) /usr/local/bin/gzip ++ set Log(compressProg) /usr/bin/gzip Added: head/usr.bin/patch/tests/PR74127-good.diff ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/usr.bin/patch/tests/PR74127-good.diff Thu Sep 5 03:16:14 2019 (r351836) @@ -0,0 +1,4 @@ +file.c +@@ -3,1 +3,1 @@ +- set Log(compressProg) gzip ++ set Log(compressProg) /usr/local/bin/gzip Added: head/usr.bin/patch/tests/PR74127-repro.diff ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/usr.bin/patch/tests/PR74127-repro.diff Thu Sep 5 03:16:14 2019 (r351836) @@ -0,0 +1,4 @@ +file.c +@@ -5,1 +5,1 @@ +- set Log(compressProg) /usr/local/bin/gzip ++ set Log(compressProg) /usr/bin/gzip Added: head/usr.bin/patch/tests/PR74127.in ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/usr.bin/patch/tests/PR74127.in Thu Sep 5 03:16:14 2019 (r351836) @@ -0,0 +1,14 @@ +# This program is used to compress log files +if {![info exists Log(compressProg)]} { + set Log(compressProg) gzip +} + +# Flush interval +if {![info exists Log(flushInterval)]} { + set Log(flushInterval) [expr {60 * 1000}] +} + +# This is used to turn on an alternate debug log file +if {![info exist Log(debug_log)]} { + set Log(debug_log) 0 +} Added: head/usr.bin/patch/tests/unified_patch_test.sh ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/usr.bin/patch/tests/unified_patch_test.sh Thu Sep 5 03:16:14 2019 (r351836) @@ -0,0 +1,140 @@ +# +# SPDX-License-Identifier: BSD-2-Clause-FreeBSD +# +# Copyright (c) 2019 Kyle Evans <kev...@freebsd.org> +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# 1.
