From: Paul Eggert Date: Fri, 20 Aug 1999 08:53:21 +0000 (+0000) Subject: (name_next): Use chdir_from_initial_wd, not chdir. X-Git-Url: https://git.brokenzipper.com/gitweb?a=commitdiff_plain;h=f74aea3ae3938a8a9744f96da1d89665c9d931af;p=chaz%2Ftar (name_next): Use chdir_from_initial_wd, not chdir. (name_gather): Handle `-C x -C y' correctly. Do not rely on addname to handle -C. (addname): New CHANGE_DIR parameter. Remove ugly calls to getcwd; no longer needed now that we have save-cwd. (name_match): Use chdir_from_initial_wd, not chdir. (name_from_list): Likewise. --- diff --git a/src/names.c b/src/names.c index b627729..16cba03 100644 --- a/src/names.c +++ b/src/names.c @@ -373,9 +373,7 @@ name_next (int change_dirs) if (chdir_flag) { - if (chdir (name_buffer) < 0) - FATAL_ERROR ((0, errno, _("Cannot change to directory %s"), - name_buffer)); + chdir_from_initial_wd (name_buffer); chdir_flag = 0; } else if (change_dirs && strcmp (name_buffer, "-C") == 0) @@ -426,10 +424,12 @@ name_gather (void) static struct name *buffer; static size_t allocated_length = 0; - char *name; + char const *name; if (same_order_option) { + char *change_dir = NULL; + if (allocated_length == 0) { allocated_length = sizeof (struct name) + NAME_FIELD_SIZE; @@ -437,24 +437,26 @@ name_gather (void) /* FIXME: This memset is overkill, and ugly... */ memset (buffer, 0, allocated_length); } - name = name_next (0); - if (name) + + while ((name = name_next (0)) && strcmp (name, "-C") == 0) { - if (strcmp (name, "-C") == 0) - { - char *copy = xstrdup (name_next (0)); + char const *dir = name_next (0); + if (! dir) + FATAL_ERROR ((0, 0, _("Missing file name after -C"))); + if (change_dir) + free (change_dir); + change_dir = xstrdup (dir); + } - name = name_next (0); - if (!name) - FATAL_ERROR ((0, 0, _("Missing file name after -C"))); - buffer->change_dir = copy; - } + if (name) + { buffer->length = strlen (name); if (sizeof (struct name) + buffer->length >= allocated_length) { allocated_length = sizeof (struct name) + buffer->length; buffer = (struct name *) xrealloc (buffer, allocated_length); } + buffer->change_dir = change_dir; strncpy (buffer->name, name, (size_t) buffer->length); buffer->name[buffer->length] = 0; buffer->next = NULL; @@ -464,13 +466,35 @@ name_gather (void) namelist = buffer; namelast = namelist; } + else if (change_dir) + free (change_dir); + return; } /* Non sorted names -- read them all in. */ - while (name = name_next (0), name) - addname (name); + for (;;) + { + char *change_dir = NULL; + while ((name = name_next (0)) && strcmp (name, "-C") == 0) + { + char const *dir = name_next (0); + if (! dir) + FATAL_ERROR ((0, 0, _("Missing file name after -C"))); + if (change_dir) + free (change_dir); + change_dir = xstrdup (dir); + } + if (name) + addname (name, change_dir); + else + { + if (change_dir) + free (change_dir); + break; + } + } } /*-----------------------------. @@ -478,41 +502,11 @@ name_gather (void) `-----------------------------*/ void -addname (const char *string) +addname (char const *string, char const *change_dir) { - /* FIXME: This is ugly.
