NAME
lcg_cp - copy files from/to/between Storage Element(s),
without registering anything in the file catalog.
SYNOPSIS
import lcg_util
(int returncode,
string errmsg
) lcg_cp3 (string src_file,
string dest_file,
string defaulttype,
string srctype,
string dsttype,
int nobdii,
string vo,
int nbstreams,
string conf_file,
int insecure,
int verbose,
int timeout,
string src_spacetokendesc,
string dest_spacetokendesc);
DESCRIPTION
lcg_cp
copies a Grid file to a local destination, or copie a local file to a SE (without
registering it in a file catalog).
- src_file
-
specifies the source file name: the protocol can be LFN, GUID, SURL, GSIFTP or local
file. An SURL scheme can be
sfn:
for a classical SE or
srm:.
- dest_file
-
specifies the destination. The protocol can be SURL, GSIFTP or local file. An SURL
scheme can be
sfn:
for a classical SE or
srm:.
SURL can be used only if
src_file
is GSIFTP or local file. In that case, the SURL will NOT be registered in a file
catalog.
- defaulttype
-
specifies the default SE type you want to use. But if according to the BDII the default type
is not available for this SE, it will use another type.
Possible values are:
-
- lcg_util.TYPE_NONE or 'none'
-
No default type
- lcg_util.TYPE_SE or 'se'
-
Use classic SE endpoints
- lcg_util.TYPE_SRM or 'srmv1'
-
Use SRMv1 endpoints first
- lcg_util.TYPE_SRMv2 or 'srmv2'
-
Use SRMv2 endpoints first
- srctype
-
specifies the SE type you want to use for the source file. But if according to the BDII the default type
is not available for this SE, it will fail.
Possible values are:
-
- lcg_util.TYPE_NONE or 'none'
-
No default type
- lcg_util.TYPE_SE or 'se'
-
Use classic SE endpoints
- lcg_util.TYPE_SRM or 'srmv1'
-
Use SRMv1 endpoints first
- lcg_util.TYPE_SRMv2 or 'srmv2'
-
Use SRMv2 endpoints first
- dsttype
-
specifies the SE type you want to use for the destination file. But if according to the BDII the default type
is not available for this SE, it will fail.
Possible values are:
-
- lcg_util.TYPE_NONE or 'none'
-
No default type
- lcg_util.TYPE_SE or 'se'
-
Use classic SE endpoints
- lcg_util.TYPE_SRM or 'srmv1'
-
Use SRMv1 endpoints first
- lcg_util.TYPE_SRMv2 or 'srmv2'
-
Use SRMv2 endpoints first
- nobdii
-
If set to a non-zero value, it means that you don't want to make BDII calls to get SE type. So, you must provide the type of the SE
for srm: arguments, and full endpoint in SURLs. For SE type,
defaulttype
can be used (it will be used for both source and destination).
- nbstreams
-
specifies the number of parallel streams (default 1).
- timeout
-
specifies the timeout value (default 0).
- vo
-
specifies the Virtual Organization the user belongs to. If it is
not specified, the environment variable LCG_GFAL_VO will be
used.
- conf_file
-
This argument is actually ignored.
- insecure
-
This argument is actually ignored.
- src_spacetokendesc
-
specifies the space token to use with
src_file.
Can be
NULL.
- dest_spacetokendesc
-
specifies the space token to use with
dest_file.
Can be
NULL.
- verbose
-
Verbose level. Here are the possible levels:
-
- 0
-
Only critical errors are put into errmsg.
- 1
-
Warnings are displayed on stderr as well as critical errors.
- 2
-
Debug information is displayed as well as warnings and critical errors.
NOTE
The environment variable LCG_GFAL_INFOSYS must point to the BDII, unless
nobdii
is set to a non-zero value.
To use the RLS as catalog instead of the LFC, the environment variable
LCG_CATALOG_TYPE must explicitely be set to "edg". By default, it is set to "lfc".
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation
failed. In the latter case,
errno
is set appropriately.
ERRORS
- ENOENT
-
The named file does not exist.
- EACCES
-
Permission denied.
- EFAULT
-
src_file,
dest_file
or
vo
is an invalid pointer.
- EINVAL
-
src_file
or
dest_file
has an invalid syntax.
- ECOMM
-
Communication error.
- ENAMETOOLONG
-
vo
is too long.
- EPROTONOSUPPORT
-
Access method not supported.
