Samba 2.2.8 (JYC 31-Mar-05 version) problem with records longer than 1022 bytes

[Rodney Kimber]

Thanks for your prompt response.  Unfortunately I don't have the facility to compile.  :-(    I will have to wait for your next release.

Keep up the great work.

Regards.

You are completely right. This is due from a limitation in the size of the
buffer used for temporarily reading the records from a variable-size file,
which is (as you may guess) 1024 bytes long (which limits to an actual 122,
because of the <CR><LF>).

Why is it 1024 bytes long? I have no idea. It should have been 32769,
obviously, because RMS does not accept records bigger than 32767 anyway.

I can post a fixed version of Samba/VMS (which I'll do eventually anyway),
or you can fix it yourself if you can compile, by changing the size of the
"onerec" element of the "struct fd_entry" from 1024 to 32769. I did it, and
it works...

Objet : Samba 2.2.8 (JYC 31-Mar-05 version) problem with records longer than
1022 bytes

I have been using the JYC version of Samba for a couple of months now
and think it is great.  I have just come across a problem and wonder if
there is a fix for it or if anyone else has come across a similar
situation.

If I produce a file with lines longer than 1022 bytes then Samba will
display this file as an empty file.

For example,

This file will be displayed as an empty file.

TEST1.TXT;1           File ID:  (27730,7,0)
Size:           35/112        Owner:    [SYSTEM]
File organization:  Sequential
Shelved state:      Online
Caching attribute:  Writethrough
File attributes:    Allocation: 112, Extend: 100, Global buffer count: 0
                    No version limit
Record format:      Variable length, maximum 2048 bytes, longest 1248
bytes
Record attributes:  Carriage return carriage control




This file will be displayed correctly (other than the data that is now
missing because I had to shorten the lines!!!)

TEST2.TXT;1                 File ID:  (37305,33,0)
Size:           28/32         Owner:    [SYSTEM]
File organization:  Sequential
Shelved state:      Online
Caching attribute:  Writethrough
File attributes:    Allocation: 32, Extend: 0, Global buffer count: 0
                    No version limit
Record format:      Variable length, maximum 0 bytes, longest 1022 bytes
Record attributes:  Carriage return carriage control



Thanks for your help,
