From 177547465639d4ed65646edc4f635ac84819896e Mon Sep 17 00:00:00 2001 From: Rainer Toebbicke Date: Thu, 4 Aug 2005 20:31:33 +0000 Subject: [PATCH] client-omit-zero-length-reads-20050804 The attached patch restores the behaviour of the 1.2.x client: writes appending to a file do not trigger a 0-length read which at best updates the current status. If another cache manager wrote to the same file in the meantime, the file status is updated only after the StoreData RPC (and for the changes the last one wins). --- src/afs/afs_dcache.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/afs/afs_dcache.c b/src/afs/afs_dcache.c index 2fa7a2a85..c57093fc1 100644 --- a/src/afs/afs_dcache.c +++ b/src/afs/afs_dcache.c @@ -1965,7 +1965,8 @@ afs_GetDCache(register struct vcache *avc, afs_size_t abyte, ICL_HANDLE_OFFSET(Position)); if ((aflags & 4) && (hiszero(avc->m.DataVersion))) doAdjustSize = 1; - if ((aflags & 4) && (abyte == Position) && (tlen >= size)) + if ((AFS_CHUNKTOBASE(chunk) >= avc->m.Length) || + ((aflags & 4) && (abyte == Position) && (tlen >= size)))) overWriteWholeChunk = 1; if (doAdjustSize || overWriteWholeChunk) { #if defined(AFS_AIX32_ENV) || defined(AFS_SGI_ENV) -- 2.39.5
