From 82cfce76eb5787f1a24151f6a3840a999ed82659 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Fri, 30 Jan 2009 00:53:32 +0100 Subject: archive: replaced setup_stream() with open_stream() The open_stream() method opens the input_stream. This allows the archive plugin to do its own initialization, and it also allows it to use input_stream.data. We can remove input_stream.archive now, which was unnatural to have in the first place. --- src/archive/zip_plugin.c | 28 +++++++++++----------------- 1 file changed, 11 insertions(+), 17 deletions(-) (limited to 'src/archive/zip_plugin.c') diff --git a/src/archive/zip_plugin.c b/src/archive/zip_plugin.c index d318adc0..9df449ab 100644 --- a/src/archive/zip_plugin.c +++ b/src/archive/zip_plugin.c @@ -103,24 +103,19 @@ zip_close(struct archive_file *file) /* single archive handling */ -static void -zip_setup_stream(struct archive_file *file, struct input_stream *is) +static bool +zip_open_stream(struct archive_file *file, struct input_stream *is, + const char *pathname) { zip_context *context = (zip_context *) file; + ZZIP_STAT z_stat; + //setup file ops is->plugin = &zip_inputplugin; //insert back reference - is->archive = context; + is->data = context; //we are seekable (but its not recommendent to do so) is->seekable = true; -} - - -static bool -zip_is_open(struct input_stream *is, const char *pathname) -{ - zip_context *context = (zip_context *) is->archive; - ZZIP_STAT z_stat; context->file = zzip_file_open(context->dir, pathname, 0); if (!context->file) { @@ -135,14 +130,14 @@ zip_is_open(struct input_stream *is, const char *pathname) static void zip_is_close(struct input_stream *is) { - zip_context *context = (zip_context *) is->archive; + zip_context *context = (zip_context *) is->data; zzip_file_close (context->file); } static size_t zip_is_read(struct input_stream *is, void *ptr, size_t size) { - zip_context *context = (zip_context *) is->archive; + zip_context *context = (zip_context *) is->data; int ret; ret = zzip_file_read(context->file, ptr, size); if (ret < 0) { @@ -155,7 +150,7 @@ zip_is_read(struct input_stream *is, void *ptr, size_t size) static bool zip_is_eof(struct input_stream *is) { - zip_context *context = (zip_context *) is->archive; + zip_context *context = (zip_context *) is->data; return ((size_t) zzip_tell(context->file) == context->length); } @@ -163,7 +158,7 @@ static bool zip_is_seek(G_GNUC_UNUSED struct input_stream *is, G_GNUC_UNUSED off_t offset, G_GNUC_UNUSED int whence) { - zip_context *context = (zip_context *) is->archive; + zip_context *context = (zip_context *) is->data; zzip_off_t ofs = zzip_seek(context->file, offset, whence); if (ofs != -1) { is->offset = ofs; @@ -186,7 +181,6 @@ static const char *const zip_extensions[] = { }; static const struct input_plugin zip_inputplugin = { - .open = zip_is_open, .close = zip_is_close, .read = zip_is_read, .eof = zip_is_eof, @@ -199,7 +193,7 @@ const struct archive_plugin zip_plugin = { .open = zip_open, .scan_reset = zip_scan_reset, .scan_next = zip_scan_next, - .setup_stream = zip_setup_stream, + .open_stream = zip_open_stream, .close = zip_close, .suffixes = zip_extensions }; -- cgit v1.2.3
