File size limit

Chantal Thibodeau
Hi
 
We are using VSE 3.0 for over 15 years and in this period, files are getting bigger and bigger.  We are unable to read files larger than 4 gigs.  At writing, there is no problem.
 
I know this is because of the "maxInteger" value.
 
Is there a way to bypass that limit (except splitting larger files in two) ?
 
Thanks

Hi!
 
The Win32 API does support 64 bit file pointers.
Currently the methods calling the API use zero for the upper 32 bit. This limits the files to 4GB.
I think it should be possible to enhance the File related classes to support the 64 bit file pointers.

See: http://msdn.microsoft.com/en-us/library/windows/desktop/aa365541(v=vs.85).aspx
 
Perhaps somebody already did this and is willing to share it?
 
Regards,
   Andreas

Try

FileHandle >>position: anInteger

| large return |

large := WinLargeInteger fromInteger: anInteger.

return := KernelLibrary

setFilePointer: self asParameter

offset: (large bytesAtOffset: 0 count: 4)

offsetHigh: (large bytesAtOffset: 4 count: 4)

move: FileBegin.

return = 16rFFFFFFFF ifTrue: [^self osError]

More info.

There are two additional methods you should also change:

FileHandle >> #endByte

| large success |

large := WinLargeInteger new.

success := KernelLibrary getFileSize: self asParameter fileSizeHigh: large.

success ifFalse: [self osError].

^large asUnsignedInteger


KernelDLL >> #getFileSize: aFileHandle fileSizeHigh: aWinLargeInteger

<api: GetFileSizeEx ulong struct boolean>

^self invalidArgument

I think it should be possible to enhance the File related classes to support the 64 bit file pointers.

See: http://msdn.microsoft.com/en-us/library/windows/desktop/aa365541(v=vs.85).aspx

 

Perhaps somebody already did this and is willing to share it?

Subject: File size limit

Hi

 

We are using VSE 3.0 for over 15 years and in this period, files are getting bigger and bigger.  We are unable to read files larger than 4 gigs.  At writing, there is no problem.

 

I know this is because of the "maxInteger" value.

 

Is there a way to bypass that limit (except splitting larger files in two) ?

 

Thanks

Hi Leandro,

don’t know, guess we just scanned the class for methods using file pointers, and so fixed it.

I liked your catch of FileHandle>>#position and have a question: Is this method ever used?

Thank to you all guys.
 
I tried yesterday, with an additional modificaiton to I don't remember wich method, but without your last methods.
 
I was able to read up to about 8 gigs, but no more.  I will try later today with your last modifications.  But 8 gigs is already far better than 4 gigs.
 
I'll keep you informed.

Chantal,

I've tested the code (mine + Manfred's) with 4, 8 and 12 GB and it worked just fine.

UTF-8

Chantal Thibodeau
In reply to this post by Leandro Caniglia
Hi everybody
 
Has someone already tried to read UTF-8 strings ?
 
My problem is we receive UTF-8 XML files, that are then put in a MySQL database, in UTF8 format.
 
When I read them, all the accents are screwed up.  I looked on the net but I only find code for Squeak or other, and I am unable to make it works.
 
Thanks

Hi:

Download
http://www.infoil.com.ar/seaside/downloads/Seaside%203.0%20rc3%202010-NOV-06.zip

Inside the zip file there is a folder "US" containing Dolphin
Smalltalk source code to handle UTF-8 strings. Maybe you can port the
code to VS. The implementation is based on standard windows api and
standard Smalltalk so I guess is an easy job :)

Use MultiByteToWideChar with CP_UTF8 to convert the UTF-8 string to Unicode and then use WideCharToMultiByte to convert the unicode string the the codepage of your SQL server (or leave it in unicode if you use the unicode fields in the database)

Re: UTF-8

Jon Raiford
In reply to this post by Chantal Thibodeau
If the accents are your only problem, it sounds as if something is translating the text for you.  Make sure you have configured MySQL to accept and hold unicode data.  If not, the database itself will convert the text to latin and the accents are lost.  This link might help: http://dev.hubspot.com/bid/7049/MySQL-and-Unicode-Three-Gotchas

Also, since Windows 2000, Windows APIs use UTF16 (previously used UCS2), so as Todor pointed out you may need to convert your UTF8 to UTF16 if you want to call functions that expect Unicode parameters.
