Is there a limitation in exiv2's functionality that prevents it from inserting the tag 'Exif.SubImage1.OpcodeList3' to a DNG file?
I am trying to copy this tag from one DNG file to another with no success.
My source file was printed using:
exiv2.exe -b -pa file.dng > output.txt
The file output.txt contains:
Exif.SubImage1.OpcodeList3 Undefined 184 0 0 0 1 0 0 0 1 1 3 0 0 0 0 0 0 0 0 0 164 0 0 0 3 63 240 0 0 119 176 58 28 191 185 132 79 191 248 95 209 63 154 58 10 83 149 62 10 191 117 109 20 1 60 213 11 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 63 240 0 0 0 0 0 6 191 185 168 230 29 114 106 51 63 154 226 203 140 13 160 159 191 117 201 88 36 225 127 123 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 63 239 255 253 213 88 87 206 191 185 163 231 88 112 250 50 63 155 248 100 114 115 143 207 191 118 115 180 47 58 216 144 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 63 223 227 192 112 254 60 7 63 224 0 0 0 0 0 0
I'm trying to add this tag to a different DNG file that doesn't have it by (for example) a command file:
add Exif.SubImage1.OpcodeList3 Undefined "0 0 0 1 0 0 0 1 1 3 0 0 0 0 0 0 0 0 0 164 0 0 0 3 63 240 0 0 119 176 58 28 191 185 132 79 191 248 95 209 63 154 58 10 83 149 62 10 191 117 109 20 1 60 213 11 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 63 240 0 0 0 0 0 6 191 185 168 230 29 114 106 51 63 154 226 203 140 13 160 159 191 117 201 88 36 225 127 123 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 63 239 255 253 213 88 87 206 191 185 163 231 88 112 250 50 63 155 248 100 114 115 143 207 191 118 115 180 47 58 216 144 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 63 223 227 192 112 254 60 7 63 224 0 0 0 0 0 0"
But the file remains unchanged.
I also tried things like: add Exif.SubImage1.OpcodeList3 Undefined "0 0 0 1 0"
But still the tag is not added. I suspect that exiv2 doesn't support the insertion of this tag.
Am I doing something wrong or is this not supported?
Problem solved: the answer here (with respect to OpcodeList1) explains why such a tag is not manipulated by exiv2. To overcome this, I changed tiffimage.cpp by replacing:
if ( pPrimaryGroups != 0
&& !pPrimaryGroups->empty()
&& group != ifd0Id) {
#ifdef DEBUG
ExifKey key(tag, groupName(group));
std::cerr << "Image tag: " << key << " (2)\n";
#endif
return true;
}
with:
if ( pPrimaryGroups != 0
&& !pPrimaryGroups->empty()
&& group != ifd0Id) {
bool opcode3 = tag == 0xc74e;
#ifdef DEBUG
ExifKey key(tag, groupName(group));
if (!opcode3)
std::cerr << "Image tag: " << key << " (2)\n";
else
std::cerr << "Not an image tag: " << key << " (2)\n";
#endif
return !opcode3;
}

How can I do that?
the following command "awk '{print $8}' file" works fine
I do not want to wait for Oracle DataDump expdb to finish writing to dump file.
So I start reading data from the moment it's created.
Then I write this data to another file.
It worked ok - file sizes are the same (the one that OracleDump created and the one my data monitoring script created).
But when I run cmp it shows difference in 27 bytes:

Even if I extract more data the difference is still 27 bytes but different addresses/values:

Some writes are the same.
Is there a way know addresses of bytes which will differ?
ls -al ora.dmp
-rw-r--r-- 1 bicadmin bic 2760704 Jun 20 11:09 ora.dmp
python -c 'print 2760704-2674742'

How can update my monitored copy after DataDump updated the original at adress 2674742 using Python for example?
Exact same thing happens if I use COMPRESSION=DATA_ONLY option.
Update: Figured how to sync bytes that differ between 2 files:

The reason I do dmp file monitoring is because it cuts backup time in half.
I am using bufio to append byte arrays to a file. When I use cat on it I get:

So arrays of bytes. Now I want to read the file into memory, so I use:
content, err := ioutil.ReadFile(filename)
But when I display the content variable I get a completely different output than the contents of the file (and one array instead of many). What's wrong?
You wrote it wrong to the file. Its human readable format, should be binary.
My guess you used something like fmt.Fprintln(file, byte_slice) or variants.
It must be fmt.Fprintf(file, "%s", byte_slice) or similar.
Please, show us code how you write to the file.
So what think is happening is that the content inside of that file is a string. When you pull it out of the file it converts that string to bytes. What you need to do is convert those bytes to a string before you append to the file and then convert them back when you pull from the file

I've been playing with grouping() and rollup(), but I always get duplicated rows and unwanted null values.
If you have problems, grouping_id function will help you.
(You can select grouping_id(col), but also grouping_id(col1, col2, col3, etc..))
But your case is simpler.
It is like:
drop table fg_test_group;
create table fg_test_group (a number, b number, c number, d number);
insert into fg_test_group values (1, 2, 3, 4);
insert into fg_test_group values (2, 2, 3, 4);
insert into fg_test_group values (3, 2, 3, 4);
select nvl(to_char(a), 'total') as a , sum(b), sum(c), sum(d), grouping_id(a)
from fg_test_group
group by rollup (a)
;
where a is Status in your case.
CREATE TABLE TEST1 (STATUS VARCHAR2(10), R1 NUMBER, R2 NUMBER, R3 NUMBER);
INSERT INTO TEST1 VALUES ('ACCEPTED', 322,241,278);
INSERT INTO TEST1 VALUES ('EXECUTED', 0, 80, 1);
INSERT INTO TEST1 VALUES ('FREQ', 0, 55, 2);
COMMIT;
