To: edk2-devel; +Cc: Chen A Chen, Jaben Carsey, Tapan Shah
The patch adds the "-sfo" support to "dmpstore" command.
1. For "-l" (load variable from file), when the variable
content can be updated, the new variable data is displayed
in SFO format, otherwise, the new variable data is not
displayed. So that the SFO consumer can know which variables
are updated by parsing the SFO.
2. For "-d" (delete variable), when the variable can be deleted
successfully, only the variable name and GUID are displayed in
SFO but the attribute/data/data size are displayed as empty to
indicate the deletion happened; otherwise, the variable is not
displayed.
3. For displaying variable, when the variable specified by name
and GUID cannot be found, an error message is displayed; Otherwise,
the SFO is displayed.
E.g.: "dmpstore -guid GuidThatDoesntExist -sfo" produces output
as:
ShellCommand,"dmpstore"
VariableInfo,"","GuidThatDoesntExist","","",""
"dmpstore NameThatDoesntExist -guid GuidThatDoesntExist -sfo"
produces output as:
ShellCommand,"dmpstore"
dmpstore: No matching variables found. Guid GuidThatDoesntExist, Name
NameThatDoesntExist
The difference between the above 2 cases is that former one only
specifies the GUID, but the latter one specifies both name and GUID.
Since not specifying GUID means to use GlobalVariableGuid,
"dmpstore NameThatDoesntExist -sfo" produces the similar output as
latter one.
I personally prefer to always produce SFO output for both cases.
But the above behavior is the discussion result between HPE engineers.

Two comments:
1. Missing help output update for -sfo support in dmpstore command.
2. BinaryToHexString() is missing input parameter NULL and out of bound size check before access.

Subject: [PATCH] ShellPkg/dmpstore: Support "-sfo"
The patch adds the "-sfo" support to "dmpstore" command.
1. For "-l" (load variable from file), when the variable
content can be updated, the new variable data is displayed
in SFO format, otherwise, the new variable data is not
displayed. So that the SFO consumer can know which variables
are updated by parsing the SFO.
2. For "-d" (delete variable), when the variable can be deleted
successfully, only the variable name and GUID are displayed in
SFO but the attribute/data/data size are displayed as empty to
indicate the deletion happened; otherwise, the variable is not
displayed.
3. For displaying variable, when the variable specified by name
and GUID cannot be found, an error message is displayed; Otherwise,
the SFO is displayed.
E.g.: "dmpstore -guid GuidThatDoesntExist -sfo" produces output
as:
ShellCommand,"dmpstore"
VariableInfo,"","GuidThatDoesntExist","","",""
"dmpstore NameThatDoesntExist -guid GuidThatDoesntExist -sfo"
produces output as:
ShellCommand,"dmpstore"
dmpstore: No matching variables found. Guid GuidThatDoesntExist, Name
NameThatDoesntExist
The difference between the above 2 cases is that former one only
specifies the GUID, but the latter one specifies both name and GUID.
Since not specifying GUID means to use GlobalVariableGuid,
"dmpstore NameThatDoesntExist -sfo" produces the similar output as
latter one.
I personally prefer to always produce SFO output for both cases.
But the above behavior is the discussion result between HPE engineers.

Ray,
Chris and I looked at the patch closely again and saw that your change also includes -sfo support for -l and -s flags which is not supported according to the latest spec. See below syntax from spec:
dmpstore [-b] [-d] [-all | (-guid guid)] [variable] [-sfo]
dmpstore [-all | (-guid guid)] [variable] [-s file]
dmpstore [-all | (-guid guid)] [variable] [-l file]
If we want to include -l and -s support with -sfo flag, then we need to define new SFO tables and it requires UEFI Shell spec. update. Currently non-sfo mode for -l and -s flags do not display variable data and current -sfo table has variable data column defined.
We also saw that -l/-s -sfo mode suppresses error and that's confusing from user prospective as suppressing error does not provide enough information to user about what happened for an individual variable. This should be handled with new SFO tables for -l/-s flags and do it later after Shell spec. update.
Thanks,
Tapan

Subject: RE: [PATCH] ShellPkg/dmpstore: Support "-sfo"
Two comments:
1. Missing help output update for -sfo support in dmpstore command.
2. BinaryToHexString() is missing input parameter NULL and out of bound size check before access.

Subject: [PATCH] ShellPkg/dmpstore: Support "-sfo"
The patch adds the "-sfo" support to "dmpstore" command.
1. For "-l" (load variable from file), when the variable content can be updated, the new variable data is displayed in SFO format, otherwise, the new variable data is not displayed. So that the SFO consumer can know which variables are updated by parsing the SFO.
2. For "-d" (delete variable), when the variable can be deleted successfully, only the variable name and GUID are displayed in SFO but the attribute/data/data size are displayed as empty to indicate the deletion happened; otherwise, the variable is not displayed.
3. For displaying variable, when the variable specified by name and GUID cannot be found, an error message is displayed; Otherwise, the SFO is displayed.
E.g.: "dmpstore -guid GuidThatDoesntExist -sfo" produces output
as:
ShellCommand,"dmpstore"
VariableInfo,"","GuidThatDoesntExist","","",""
"dmpstore NameThatDoesntExist -guid GuidThatDoesntExist -sfo"
produces output as:
ShellCommand,"dmpstore"
dmpstore: No matching variables found. Guid GuidThatDoesntExist, Name NameThatDoesntExist
The difference between the above 2 cases is that former one only specifies the GUID, but the latter one specifies both name and GUID.
Since not specifying GUID means to use GlobalVariableGuid, "dmpstore NameThatDoesntExist -sfo" produces the similar output as latter one.
I personally prefer to always produce SFO output for both cases.
But the above behavior is the discussion result between HPE engineers.

Thanks for catching that. Will do that in V2 patch.

Yes I just saw that difference in Spec.
I agree to remove the sfo support for -s and -l.
But I do not think we need to define new SFO table.
I think the V1 patch's implementation can satisfy caller's information needs.
For -s, displaying the variable content in SFO is to tell caller that the exactly same
content is saved to file.
For -l, only displaying the variable content in SFO is to tell caller that the variable
listed in SFO is updated to the content shown in SFO.
Thanks/Ray
