From: Kern Sibbald Date: Sun, 24 Jun 2007 17:27:12 +0000 (+0000) Subject: kes Implement Windows reparse points -- similar to directories, but X-Git-Tag: Release-7.0.0~6085 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=26dea62aec147d0e9dfb688ce1a971c43ff53be0;p=bacula%2Fbacula kes Implement Windows reparse points -- similar to directories, but we do not descend into it. This is a first cut. They seem to be backed up, but restore is not yet tested. kes Remove restore_blocking in tls code when shutting a socket to leave it in blocking mode. Hopefully this will fix the encryption bug reported by Frank Sweetser. kes When opening a file for backup, tell the OS that we are going to read it sequentially -- optimization. kes Change variable names in authenticate_director() to not conflict with member names in bat. Caused great confusion with compiler, but no warnings. git-svn-id: https://bacula.svn.sourceforge.net/svnroot/bacula/trunk@5077 91ce42f0-d328-0410-95d8-f526ca767f89 --- diff --git a/bacula/src/baconfig.h b/bacula/src/baconfig.h index 6fa3fd6b2f..ae5bddbf9f 100644 --- a/bacula/src/baconfig.h +++ b/bacula/src/baconfig.h @@ -267,12 +267,13 @@ void InitWinAPIWrapper(); #define FT_NOOPEN 15 /* Could not open directory */ #define FT_RAW 16 /* Raw block device */ #define FT_FIFO 17 /* Raw fifo device */ -/* This directory packet is sent to the FD file processing routine so +/* The DIRBEGIN packet is sent to the FD file processing routine so * that it can filter packets, but otherwise, it is not used * or saved */ #define FT_DIRBEGIN 18 /* Directory at beginning (not saved) */ #define FT_INVALIDFS 19 /* File system not allowed for */ #define FT_INVALIDDT 20 /* Drive type not allowed for */ +#define FT_REPARSE 21 /* Win NTFS reparse point */ /* Definitions for upper part of type word (see above). */ #define AR_DATA_STREAM (1<<16) /* Data stream id present */ diff --git a/bacula/src/filed/backup.c b/bacula/src/filed/backup.c index e4651c7c19..db9193e716 100644 --- a/bacula/src/filed/backup.c +++ b/bacula/src/filed/backup.c @@ -273,6 +273,7 @@ static int save_file(FF_PKT *ff_pkt, void *vjcr, bool top_level) Jmsg(jcr, M_INFO, 1, _(" Disallowed drive type.
