From: Sergey Poznyakoff Date: Sat, 29 Jun 2013 07:31:37 +0000 (+0300) Subject: Improve checks for incompatible options. X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=cfebb3cedfb678e595b0a389074d5d7c79a33fd5;p=chaz%2Ftar Improve checks for incompatible options. * src/common.h (READ_LIKE_SUBCOMMAND): Remove define. * src/tar.c (IS_SUBCOMMAND_CLASS): New macro. (decode_options): Use IS_SUBCOMMAND_CLASS in checking option compatibility. Accept the --verify option only with subcommands that write to the archive. * tests/opcomp01.at: New test case. * tests/opcomp02.at: New test case. * tests/opcomp03.at: New test case. * tests/opcomp04.at: New test case. * tests/opcomp05.at: New test case. * tests/opcomp06.at: New test case. * tests/Makefile.am: Add new testcases. * tests/testsuite.at: Likewise. --- diff --git a/src/common.h b/src/common.h index 4f7c19f..9ac22b8 100644 --- a/src/common.h +++ b/src/common.h @@ -96,11 +96,6 @@ enum subcommand GLOBAL enum subcommand subcommand_option;
