From 22a72b911eda2f413691eed0ef2862025827a858 Mon Sep 17 00:00:00 2001 From: Raymond Lu Date: Tue, 16 Nov 2004 11:38:28 -0500 Subject: [svn-r9531] Purpose: Bug fix(#213) Description: H5Pset_fapl_family sets family member size only for creating new file. The file doesn't keep this size information. When the file is re-opened, the size of first member file is used as the member size. Solution: Assume user knows the original member size and sets it through H5Pset_fapl_family. That will be the member size. User can pass in value 0 as member size if he doesn't know the original member size. Library will choose the size of current first member size as the member file size. Platforms tested: h5committest and fuss. --- src/H5F.c | 1 + src/H5FDfamily.c | 25 ++++++++++++++++--------- test/file_handle.c | 37 ++++++++++++++++++++++++++++++------- tools/lib/h5tools.c | 3 +++ 4 files changed, 50 insertions(+), 16 deletions(-) diff --git a/src/H5F.c b/src/H5F.c index 798a28e..7db2f3f 100644 --- a/src/H5F.c +++ b/src/H5F.c @@ -1,4 +1,5 @@ /* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * + * * Copyright by the Board of Trustees of the University of Illinois. * * All rights reserved. * * * diff --git a/src/H5FDfamily.c b/src/H5FDfamily.c index 7d35b41..d22bc27 100644 --- a/src/H5FDfamily.c +++ b/src/H5FDfamily.c @@ -580,7 +580,7 @@ H5FD_family_open(const char *name, unsigned flags, hid_t fapl_id, hsize_t eof; unsigned t_flags = flags & ~H5F_ACC_CREAT; H5P_genplist_t *plist; /* Property list pointer */ - + FUNC_ENTER_NOAPI(H5FD_family_open, NULL) /* Check arguments */ @@ -621,6 +621,7 @@ H5FD_family_open(const char *name, unsigned flags, hid_t fapl_id, /* Check that names are unique */ sprintf(memb_name, name, 0); sprintf(temp, name, 1); + if (!strcmp(memb_name, temp)) HGOTO_ERROR(H5E_FILE, H5E_FILEEXISTS, NULL, "file names not unique") @@ -656,14 +657,18 @@ H5FD_family_open(const char *name, unsigned flags, hid_t fapl_id, } file->nmembs++; } - - /* - * The size of the first member determines the size of all the members, - * but if the size of the first member is zero then use the member size - * from the file access property list. + + /* + * Check if user sets member size smaller than existing first member file size. + * Return failure if so.
