sorry, same behaviour as before: PureZIP_ExtractFiles returns #Null and the
uncompressed filesize is negative.

Well, it seems to be a LONG -> QUAD conversion problem ...

Code: Select all

Structure test
  TESTL.l 
  TESTQ.q 
EndStructure
t.test\TESTL = 2500000000
t.test\TESTQ = 2500000000
Size.q = t\TESTL
Debug Size ; -1794967296 !!!
Size = t\TESTQ
Debug Size ; 2500000000

it works like this :

Code: Select all

Size.q = t\TESTL & $FFFFFFFF

BETA lib updated, please try again (sorry).

well done, gnozal! Now i can extract the file. And the progress value in the
Callback works also.

Unfortunately the FileInfo i receive with PureZIP_Archive_FileInfo() contains a
negative uncompressed filesize. But i'am sure, that you will get it.

is this a bug... or I'm a bigbug???:

I've a file (TEST-TIME.TXT) with modified date: 23/06/2006 20:53:11

When I view modified date in TEST-TIME.TXT in the zipped file, it lost a second.

Code: Select all

myFileinfo.PureZIP_FileInfo

MyZIP.s = "C:\test.zip"
MyFilesToZIP.s = "C:\TEST\test-time.txt"

Debug PureZIP_AddFiles(MyZIP, MyFilesToZIP, #PureZIP_StorePathAbsolute, #PureZIP_Recursive)

It only occurs with some hours, any help?

Really thank you, Gnozal!

... and sorry for my bad (fatal) english

The FileInfo structure has longs, as it is a ZLIB based structure. You will have to do a correction like : FileSize.q = FileInfo\unCompressedSize & $FFFFFFFF. I will add this in the manual.

I am afraid not.
I only fill a structure for ZLIB :

Code: Select all

Procedure FileTimeToDate(*FT.FILETIME)
  FileTimeToLocalFileTime_(*FT.FILETIME,FT2.FILETIME)
  FileTimeToSystemTime_(FT2,st.SYSTEMTIME)
  ProcedureReturn Date(st\wYear,st\wMonth,st\wDay,st\wHour,st\wMinute,st\wSecond)
EndProcedure
Procedure LIB_GetFileDate(File.s)
  result=0
  Handle=CreateFile_(@File,#GENERIC_READ,#FILE_SHARE_READ|#FILE_SHARE_WRITE,0,#OPEN_EXISTING,#FILE_ATTRIBUTE_NORMAL,0)
  If Handle<>#INVALID_HANDLE_VALUE
    GetFileTime_(Handle,0,0,FT.FILETIME)
    result=FileTimeToDate(FT)
    CloseHandle_(Handle)
  EndIf
  ProcedureReturn result
EndProcedure

        ; ////// Store file date into zfi.zip_file_info
        FileDate = LIB_GetFileDate(FileName)
        zfi\tm_zip\tm_sec = Val(FormatDate("%ss", FileDate))
        zfi\tm_zip\tm_min = Val(FormatDate("%ii", FileDate))
        zfi\tm_zip\tm_hour = Val(FormatDate("%hh", FileDate))
        zfi\tm_zip\tm_mday = Val(FormatDate("%dd", FileDate))
        zfi\tm_zip\tm_mon = Val(FormatDate("%mm", FileDate)) - 1
        zfi\tm_zip\tm_year = Val(FormatDate("%yyyy", FileDate))
        ; //////

Update (PB4.00 version only)

Changes :
- PureZIP now supports files up to 4 GB size.

Note
ZLIB can handle files up to 4 Gbytes, but PB longs are signed [0 - 2 Gbytes]...
So if you expect PureZIP_FileInfo\CompressedSize > 2 Gbytes or PureZIP_FileInfo\unCompressedSize > 2 Gbytes,
use quads and convert signed to unsigned !
Example : Size.q = FileInfo\unCompressedSize & $FFFFFFFF

If I try to append a zip to my executable, the executable is killed and no longer works (zip is ok). I don't know, what's the error.

Code: Select all

If PureZIP_Archive_Create(OutputDir$+Exe$, #APPEND_STATUS_CREATEAFTER)
  If ExamineDirectory(0, Dir$, "*.*")  
    While NextDirectoryEntry(0)
      If DirectoryEntryType(0) = #PB_DirectoryEntry_File
        PureZIP_Archive_Compress(Dir$+"\"+DirectoryEntryName(0), #False)            
      EndIf
    Wend
    FinishDirectory(0)
  EndIf
  PureZIP_Archive_Close()
EndIf

Yes, I noticed. I don't know what the problem is with #APPEND_STATUS_CREATEAFTER.
What I do : I simply copy the final ZIP at the end of the executable and it works.

That's the code I need. How can I do this? I've no idea how two join to files.

Gnozal, PureZIP opens a SFX module only if the data is appended at the end? I ask you this because was trying to find a solution to have inside a settings file too... How does your library installer work? As i've seen, it doesn't create any temporary files

.

I add the installer information in a file in the ZIP (in my installer it's "File_Id.Diz"). This file is not extracted but the installer reads its content with PureZIP_Archive_ExtractMem().
Download http://people.freenet.de/gnozal/PureLVSORT_.zip and open PureLVSORT-Installer.exe in WInRAR or any other archiver : you will see the "File_Id.Diz" at the root of the archive.

Oh... I see... Thanks for the tip

... I had a hunch about this but I was unsure about it
