Log: Sync libarchive with vendor branch release/2.8: 3730: Fix issue 174 (Windows path names, not relevant for FreeBSD) 3734: Merge r1989: archive_clear_error should set errno to 0. 3735: Merge r3247 from trunk: Clear errors before returning from archive_read_support_format_all() 3799: Check the position before dereferencing the pointer. This avoids dereferencing one byte past the end of a string 3824: Merge r3823 from trunk for issue 199 (hang in iso9660 reading) Obtained from: http://code.google.com/p/libarchive MFC after: 2 weeks Modified: head/lib/libarchive/archive_read_support_format_all.c head/lib/libarchive/archive_read_support_format_iso9660.c head/lib/libarchive/archive_string.c head/lib/libarchive/archive_util.c head/lib/libarchive/archive_write_disk.c Modified: head/lib/libarchive/archive_read_support_format_all.c ============================================================================== --- head/lib/libarchive/archive_read_support_format_all.c Tue Dec 20 20:29:45 2011 (r228747) +++ head/lib/libarchive/archive_read_support_format_all.c Tue Dec 20 20:34:02 2011 (r228748) @@ -1,5 +1,5 @@ /*- - * Copyright (c) 2003-2007 Tim Kientzle + * Copyright (c) 2003-2011 Tim Kientzle * All rights reserved. * * Redistribution and use in source and binary forms, with or without @@ -39,5 +39,13 @@ archive_read_support_format_all(struct a archive_read_support_format_tar(a); archive_read_support_format_xar(a); archive_read_support_format_zip(a); + + /* Note: We always return ARCHIVE_OK here, even if some of the + * above return ARCHIVE_WARN.
