From 163e96a0e619a900eab6de827c7c5749ecc9d3f2 Mon Sep 17 00:00:00 2001 From: Sergey Poznyakoff Date: Thu, 18 Sep 2014 18:06:40 +0300 Subject: [PATCH] Bugfix: entries read from the -T file did not get proper matching_flag. * src/common.h (name_add_file): Change signature. * src/names.c (name_elt_alloc_matflags): New function. (name_add_name): Use name_elt_alloc_matflags. (name_add_file): Take matching flags as third argument. (read_next_name): Remove trailing slashes. * src/tar.c (parse_opt): Pass matching_flags to name_add_file. * tests/T-dir00.at: New file. * tests/T-dir01.at: New file. * tests/Makefile.am: Add new testcases. * tests/testsuite.at: Likewise. --- src/common.h | 2 +- src/names.c | 56 +++++++++++++++++++++++++++++----------------- src/tar.c | 2 +- tests/Makefile.am | 2 ++ tests/T-dir00.at | 45 +++++++++++++++++++++++++++++++++++++ tests/T-dir01.at | 45 +++++++++++++++++++++++++++++++++++++ tests/testsuite.at | 2 ++ 7 files changed, 131 insertions(+), 23 deletions(-) create mode 100644 tests/T-dir00.at create mode 100644 tests/T-dir01.at diff --git a/src/common.h b/src/common.h index edf787c..3cc2011 100644 --- a/src/common.h +++ b/src/common.h @@ -725,7 +725,7 @@ int uname_to_uid (char const *uname, uid_t *puid); void name_init (void); void name_add_name (const char *name, int matching_flags); void name_add_dir (const char *name); -void name_add_file (const char *name, int term); +void name_add_file (const char *name, int term, int matching_flags); void name_term (void); const char *name_next (int change_dirs); void name_gather (void); diff --git a/src/names.c b/src/names.c index 594e7fd..e3e145a 100644 --- a/src/names.c +++ b/src/names.c @@ -258,6 +258,21 @@ name_elt_alloc (void) return elt; } +static struct name_elt * +name_elt_alloc_matflags (int matflags) +{ + static int prev_flags = 0; /* FIXME: Or EXCLUDE_ANCHORED? */ + struct name_elt *ep = name_elt_alloc (); + if (prev_flags != matflags) + { + ep->type = NELT_FMASK; + ep->v.matching_flags = matflags; + prev_flags = matflags; + ep = name_elt_alloc (); + } + return ep; +} + static void name_list_adjust (void) { @@ -276,20 +291,13 @@ name_list_advance (void) free (elt); } -/* Add to name_array the file NAME with fnmatch options MATCHING_FLAGS */ + +/* Add to name_array the file NAME with fnmatch options MATFLAGS */ void -name_add_name (const char *name, int matching_flags) +name_add_name (const char *name, int matflags) { - static int prev_flags = 0; /* FIXME: Or EXCLUDE_ANCHORED? */ - struct name_elt *ep = name_elt_alloc (); + struct name_elt *ep = name_elt_alloc_matflags (matflags); - if (prev_flags != matching_flags) - { - ep->type = NELT_FMASK; - ep->v.matching_flags = matching_flags; - prev_flags = matching_flags; - ep = name_elt_alloc (); - } ep->type = NELT_NAME; ep->v.name = name; name_count++; @@ -305,9 +313,10 @@ name_add_dir (const char *name) } void -name_add_file (const char *name, int term) +name_add_file (const char *name, int term, int matflags) { - struct name_elt *ep = name_elt_alloc (); + struct name_elt *ep = name_elt_alloc_matflags (matflags); + ep->type = NELT_FILE; ep->v.file.name = name; ep->v.file.term = term; @@ -389,6 +398,15 @@ add_file_id (const char *filename) file_id_list = p; return 0; } + +/* Chop trailing slashes. */ +static void +chopslash (char *str) +{ + char *p = str + strlen (str) - 1; + while (p > str && ISSLASH (*p)) + *p-- = '\0'; +} enum read_file_list_state /* Result of reading file name from the list file */ { @@ -428,7 +446,7 @@ read_name_from_file (struct name_elt *ent) if (counter == name_buffer_length) name_buffer = x2realloc (name_buffer, &name_buffer_length); name_buffer[counter] = 0; - + chopslash (name_buffer); return (counter == 0 && c == EOF) ? file_list_end : file_list_success; } @@ -518,7 +536,6 @@ copy_name (struct name_elt *ep) { const char *source; size_t source_len; - char *cursor; source = ep->v.name; source_len = strlen (source); @@ -536,11 +553,7 @@ copy_name (struct name_elt *ep) name_buffer = xmalloc(name_buffer_length + 2); } strcpy (name_buffer, source); - - /* Zap trailing slashes. */ - cursor = name_buffer + strlen (name_buffer) - 1; - while (cursor > name_buffer && ISSLASH (*cursor)) - *cursor-- = '\0'; + chopslash (name_buffer); } @@ -553,7 +566,8 @@ static int matching_flags; /* exclude_fnmatch options */ the request to change to the given directory.
