Re: [twsocket] Converting a cache to AVL tree

Yes it is indeed faster! Hard to measure but in the old version, during
deletion it used to take n/2 time. n is the number of files which could
reach up to 100K!

Hello Arno,

It seems to work perfectly now with your advice! See:
www.iqproxyserver.comis being served with the beta version using ICS
TCacheTree.
Thanks a lot,

Re: [twsocket] Converting a cache to AVL tree

[Fastream Technologies]

I still get occasional AVs in shut down. It is in cacheNode deletion. This
is the code:

bool __fastcall ProxyCache::deleteFileFromDiskCacheWRTIndex(DiskFileCache
*bufferFileCache, bool alreadyMarkedAsToDelete)
{
 if(!bufferFileCache)
  return false;
 if(bufferFileCache->cacheTreeNode)
 {
  bufferFileCache->cacheTreeNode->Data = NULL;
  diskFileCacheIndex->Remove(bufferFileCache->cacheTreeNode); << RANDOM AV
HERE!
  bufferFileCache->cacheTreeNode = NULL;
 }
 cacheCurrentDiskSize -= bufferFileCache->getAndZeroSize();
 if(!bufferFileCache->getWriteLock() && !bufferFileCache->getIsReadLock())
 {
  bufferFileCache->saveHeaderDataToIniFile(true);
  delete bufferFileCache;
  return true;
 }
 else
 {
  if(!alreadyMarkedAsToDelete)
   bufferFileCache->setDeleteFileASAP();
  return false;
 }
}
//--
What I guess is multiple DiskFileCache's are assigned the same cacheNode
and it is being deleted twice but not sure. This TCacheTree is not that
flexible as it seems...

Re: [twsocket] Converting a cache to AVL tree

Hi Arno,

procedure TCacheTree.Insert(
Key   : String;
Data  : Pointer;
Len   : Integer;
TimeStamp : TDateTime = MinDT;
Expires   : TDateTime = MinDT;
UpdateTime: Boolean = True;
UpdateData: Boolean = True);
var
CacheNode,
ResNode : TCacheNode;
NewIdx,
ResIdx : TCacheIdxNode;
Found : Boolean;
begin
CacheNode := TCacheNode.Create(Key, Data, Len);
FFoundNode := nil;
ResNode := TCacheNode(SearchAndInsert(CacheNode, Found));
if not Found then  // Primary key not found = new cache Node added
begin
NewIdx := TCacheIdxNode.Create(CacheNode, TimeStamp, Expires);
ResIdx := TCacheIdxNode(FSecIdxTree.SearchAndInsert(NewIdx, Found));
if not Found then   // New TimeStamp inserted
CacheNode.FIdxRef := NewIdx
else begin  // TimeStamp exists, add a duplicate
if not Assigned(ResIdx.FDups) then
begin
ResIdx.FDups := TSecIdxDuplicates.Create;
ResIdx.FDups.InsertEnd(ResIdx);
end;
ResIdx.FDups.InsertEnd(NewIdx);
CacheNode.FIdxRef := NewIdx;
end;
FLastInsertedNode := CacheNode;  // Fastream
end
else begin // Primary key found - update data and secondary index
if UpdateData then
begin
// Old data needs to be freed
TriggerFreeData(ResNode.FData, ResNode.FLen);
// Update Data
ResNode.FData := Data;
ResNode.FLen  := Len;
end;
if UpdateTime then
begin
//Update TimeStamp (delete and new)
FSecIdxTree.Remove(ResNode.FIdxRef);
NewIdx := TCacheIdxNode.Create(ResNode, TimeStamp, Expires);
ResIdx := TCacheIdxNode(FSecIdxTree.SearchAndInsert(NewIdx,
Found));
if not Found then
ResNode.FIdxRef := NewIdx
else begin   // Time value exists, create a duplicate
if not Assigned(ResIdx.FDups) then
begin
ResIdx.FDups := TSecIdxDuplicates.Create;
ResIdx.FDups.InsertEnd(ResIdx);
end;
ResIdx.FDups.InsertEnd(NewIdx);
ResNode.FIdxRef := NewIdx
end;
end;
FLastInsertedNode := ResNode; // Fastream
// not new
FreeAndNil(CacheNode);
end;
end;

I think this is better to get the last insertion node.

Re: [twsocket] Converting a cache to AVL tree

[Fastream Technologies]

Hi again,

I think the problem is in the delete routine:

bool __fastcall ProxyCache::deleteFileFromRAMCacheWRTIndex(RAMFileCache
*bufferFileCache, bool alreadyMarkedAsToDelete)
{
 if(!bufferFileCache)
  return false;
 if(bufferFileCache->cacheTreeNode)
 {
  RAMFileCacheIndex->Remove(bufferFileCache->cacheTreeNode);
  bufferFileCache->cacheTreeNode = NULL;
 }
 cacheCurrentRAMSize -= bufferFileCache->getAndZeroSize(); // first time it
subtracts and then returns 0
 if(!bufferFileCache->getWriteLock() && !bufferFileCache->getIsReadLock())
 {
  delete bufferFileCache;
  return true;
 }
 else
 {
  if(!alreadyMarkedAsToDelete)
   bufferFileCache->setDeleteFileASAP();
  return false;
 }
}
//--

if(bufferFileCache->cacheTreeNode)
{
RAMFileCacheIndex->Remove(bufferFileCache->cacheTreeNode);
bufferFileCache->cacheTreeNode = NULL;
}

When this is entered, the data pointer or the bufferfilecache is NOT
deleted by the tree, right? Also my question is pending, how do I get the
tcachenode of the lastly inserted/updated data??

Best Regards,

SZ

Both of these do not work. Must I pass Now() while updating? I am just

FYI, this is the code:

  RAMFileCacheIndex->OnList = CacheTreeOnListForRAM;
  RAMFileCacheIndex->ListTree();

  for(int i = RAMFileCacheIndexList->Count - 1; i >= 0; --i)
   
deleteFileFromRAMCacheWRTIndex((RAMFileCache*)RAMFileCacheIndexList->Items[i],
false); (basically deletes the data

  RAMFileCacheIndexList->Clear();

Re: [twsocket] Converting a cache to AVL tree

Let me elaborate the issue: In our caches, we may have duplicate URLs. How
would one update a timestamp with tcachenode pointer?

Critical question:  Node.IdxRef.TimeStamp = updatedDate;

Would this work? Because we may have duplicates...

Re: [twsocket] Converting a cache to AVL tree

[Fastream Technologies]

Arno,

The deletions occur once in a day/week or so, when the end admin user
clicks a button in GUI. It is not a part of every second cache operation.
What is the easiest/safest way to delete by iteration?

a. Implement a new TCacheTree with IPv6 AVLPointerTree?
b. A very slow workaround for the current class (speed is NOT an issue).

Ok but how do I delete with respect to a data->property?? We use regex and
string comparison for this! If you can help me with it, I will appreciate.
We can be sponsors for this feature. I think we can live with OnList way

Re: [twsocket] Converting a cache to AVL tree

[Fastream Technologies]

Do you mean the tree self-destructs nodes and I will be notified of it to
delete? Or is it optional? Basically here is my destruction function:

bool __fastcall ProxyCache::deleteFileFromRAMCacheWRTIndex(RAMFileCache
*bufferFileCache, bool alreadyMarkedAsToDelete)
{
 if(!bufferFileCache)
  return false;

 if(bufferFileCache->cacheTreeNode)
 {
  RAMFileCacheIndex->Remove(bufferFileCache->cacheTreeNode);
  bufferFileCache->cacheTreeNode = NULL;
 }
 cacheCurrentRAMSize -= bufferFileCache->getAndZeroSize(); // first time it
subtracts and then returns 0
 if(!bufferFileCache->getWriteLock() && !bufferFileCache->getIsReadLock())
 {
  delete bufferFileCache;
  return true;
 }
 else
 {
  if(!alreadyMarkedAsToDelete)
   bufferFileCache->setDeleteFileASAP();
  return false;
 }
}
//--

IOW, in our cache one URL can have just one entry in the tree but many
sockets can be pending to delete. It has to wait until the very last socket
connection to delete the actual object.

Re: [twsocket] Converting a cache to AVL tree

The component I tried to use is TCacheTree. It has a timeout argument for
each added item. I do not want any timers or any timeouts yet liked the
component. Is there a way to omit expiration. I will use my own code for it.

Re: [twsocket] Restricted ports on the Mac

Ports < 1024 require admin rights on most OS. Never used Mac OS X but maybe
it has a mechanism similar to UAC(?)

[twsocket] Keeping connection open in TSslHttpCli

[Fastream Technologies]

Hello,

In our web proxy server, we use pooled ICS web clients and close the
connection/abort when the server THttpConnection is returned to its pool
(when the server socket is closed). I wonder how we can keep the HttpCli
open for more speed. For example what would happen in the scenario below:

- THttpConnection closed/has to return to pool
- THttpCli is open to server
- both ThreadDetach
- Web server shuts down THttpCli connection
- ThreadAttach
- New THttpConnection and the same THttpCli is assigned
- ThreadDetach
- ThreadAttach
- GetAsync
- ?
Would it raise an exception or detect the session is ended?

Best Regards,

SZ

Hello Wilfried,

You create one TSslContext per SSL certificate your server has and you need
to assign one of it to each ICS SSL instance. It is useful in sharing SSL
context objects accross many SSL client/servers in a thread.

We have made some ICS web server speed improvements too. Together with RAM
cache and keep-alive, it could reply 7700 requests/sec for a 1KB file! The
good thing with proxy servers is that it does not matter if it is a txt or a
php file. 1460 bytes is the Ethernet frame payload size. We have made some
buffering in cache reads so that it now reads 16-32-64KB and pumps in 1460
bytes each time, reducing cache critical section wait time.

What I want to know is we already have the cache memory stream which we read
from and there is multiple copying of data as TMemoryStream->FDocBuf->ICS
internal buffer->Winsock. If only we cıould remove the first part and copy
directly to ICS, it will be faster.

much speed as it gets.

I have a working proxy server which I want TSslHttpCli to connect via

[twsocket] Sponsorship inquiry for TSslHttpCli

[Fastream Technologies]

Hello,

We use the TSslHttpCli for our secure web reverse proxy. When SSL is also
enabled on web server, in order for it to work with DNS pointing the
www.domain.com to reverse proxy and the web server running on the same
certificate, end users define their web servers with numeric IPs. However
when they do so, this time the SSL verification between the proxy and web
server fails as TSslHttpCli sends no SSL domain name since the web server IP
is numeric! To overcome this, we have told customers to use hosts file
setting on proxy machine (as a workaround) which is perceived as a low
quality solution... ;-(

We want to sponsor for a property in this component as SslDomainName.
Actually I think the SNI code should have included a similar feature but I
am unable to find anything similar in demos. We can pay for time or for
deliverables.

Best Regards,

SZ

Re: [twsocket] THttpCli bug with no-content-length and no chunckedencoding

[Fastream Technologies]

Dear Arno,

The new problem happens with GET on pages with no content-length and no
chunked-encoding. This bug had once been there, and then was fixed. Now it
happens again. Please try against such a page with Httptst demo and you will
see that the OnDocData is never called but instead all the data is assumed
as header lines. I am using v7.18.
Thanks for your efforts,

Re: [twsocket] THttpCli bug with no-content-length and no chuncked encoding

[Fastream Technologies]

We had actually paid for HttpCli bug fixes to Arno. I hope he will show up
and fix it soon. We do not use content coding so I do not think Yuri's fix
would work.

BTW Yuri, your code lacks the latest 7.18 bug fix by us (me and Arno).

[twsocket] THttpCli bug with no-content-length and no chuncked encoding

[Fastream Technologies]

Hello all,

Data is pumped in the header in this case. I mean there is no ondocdata
called!

The conditionals I use are,
NO_STRICT;NOFORMS;NO_DEBUG_LOG;USE_SSL;SECURITY_WIN32;NO_ADV_MT;NO_ADVANCED_HTTP_CLIENT_FEATURES

Hope somebody could help.

Re: [twsocket] How do they accomplish Mbps of speed on single socket between co

[Fastream Technologies]

Hello,

With your advice, local-to-local I saw speeds of 650MByte per sec--10%
faster than IIS! I have an idea for futher speed:

procedure TIcsBufferHandler.Lock;
begin
EnterCriticalSection(FCritSect);
end;

{* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*}
procedure TIcsBufferHandler.UnLock;
begin
LeaveCriticalSection(FCritSect);
end;
We use NO_ADV_MT. Shouldn't these be IFNDEF'ed for it?

I mean I have on my server in Canada IIS and our ICS server. When I download
from there with high latency and high bandwidth, ICS was slow. Before
reading your post I had read that I need to increase window size. I have
made it 128KB and now the download speed is 180KB/s. Let's say I make this
1MB, would Windows go out of non-paged RAM? That is my concern...

Hello,

I think you should also test it with BCB only in a vm. Or maybe I am missing
something terribly. Yesterday I installed the trial version, then
uninstalled and today ordered the real one and had it download the install
files to a different folder. Desperately lost...

Did you really test this without any Delphi installed with just BCB

What would you say to this error under BCB XE2 Pro:

Re: [twsocket] Isn't it possible to compile ICS with BCB XE2 Pro?

[Fastream Technologies]

I think it does not let runtime-only BCB packages. I got over it by using
the design time package but after making my custom settings the compiler
gives:

[Fatal Error] Cannot create file "". The filename, directory name, or volume
label syntax is incorrect

of which when I hit F5 gives "Keyword not defined. I am uploading the file
to http://www.fastream.com/ics/bcbxe2package.rar
Hope you can help.

Re: [twsocket] ICS HTTP Client POST fails in 6 out of 16 test cases

[Fastream Technologies]

To test the code, just install PHP to IIS or Apache, then unrar test.php in
the root and POST anything to,

http://localhost/test.php?m=11

You will see that the component never returns anything and the next request
gives "busy" exception!

[twsocket] ICS HTTP Client POST fails in 6 out of 16 test cases

[Fastream Technologies]

Hello,

I have had a coder code a PHP script for this purpose. In the script the
buggy cases are marked in source. Just POSTed with ICS Post demo to IIS 7.5
and the bug showed its ugly face. Since we have a big customer awaiting the
fix, if somebody could sacrifice his Sunday to help fix it out, we will
donate $100 to him to his Paypal or share-it or whatever. The test case is
at,

http://www.fastream.com/ics/ICSHTTPCliPostBugDemo.rar
Currently it should not be possible to write a web service call code with

Re: [twsocket] HTTP Client POST under WinXPSP3 issue

[Fastream Technologies]

Basically this is my code. It works on Win7/2008 for POST as well as for
GET/HEAD (which return just 403) but under XPSP3 GET/HEAD still works from
browser but the POST fails. Just returns nothing--as if it is aborted. I do
not have debugger on the XP machine but one thing very strange is it works
when the engine (server) is in debug exe but not when it is as service. The
service is optimized code. So I am clueless right now.

void __fastcall AdminServer::HTTPServerPostDocument(TObject *Sender, TObject
*Client, Overbyteicshttpsrv::THttpGetFlag &Flags)
{
 THttpConnection *httpClient = (THttpConnection*)Client;
 AdminServerConnectionData *connectionData =
(AdminServerConnectionData*)(void*)httpClient->Tag;
 connectionData->docSize = 0;
 forceRestart = false;
 if(httpClient->RequestContentLength <= (4 * 1024 * 1024))
  Flags = hgAcceptData;
}
//---
void __fastcall AdminServer::HTTPServerPostedData(TObject *Sender, TObject
*Client, WORD ErrCode)
{
 THttpConnection *httpClient = (THttpConnection*)Client;
 AdminServerConnectionData *connectionData =
(AdminServerConnectionData*)(void*)httpClient->Tag;
 if(ErrCode)
 {
  httpClient->PostedDataReceived();
  httpClient->Abort();
 }
 else
 {
  int Len = httpClient->Receive((void*)connectionData->buffer, 8192);
  if(Len <= 0)
   return;
  connectionData->stream->Write((void*)connectionData->buffer, Len);
  connectionData->docSize += Len;

  if(connectionData->docSize >= httpClient->RequestContentLength)
  {
   httpClient->PostedDataReceived();
   connectionData->stream->Seek(0, 0);
   TMemoryStream *responseXML = processRequest(connectionData->stream,
httpClient);
   Overbyteicshttpsrv::THttpGetFlag Flags;
   httpClient->DocStream = responseXML;
   httpClient->SendStream();
  }
 }
}

No, it must be with THttpServer on very fast (say local) connections. With

Re: [twsocket] HTTP Client POST under WinXPSP3 issue

[Fastream Technologies]

Well, it turned out to be an ICS web server issue on XP as the client works
well with other IPs. Also the server engine debug exe (which is just the
service code wrapped in simple GUI) also works yet the service! I cannot
access the Services section of Windows too--gives error about ActiveX. The
interesting thing is all these that happen under vmware in XP also happens
to other people as well!

So would the additional domains work with ICS or not? If not, what to do? I
notice our customers are getting more and more high end every day and this
is making them harder to support.

Honestly I am not yet sure. It is just one customer says "he could not get
SAN SSL cert to work". I told him to alter Accepted Hosts and use the
wildcard SNI domain. I asked here to learn if it is supported or not. If it
is not, I need to know to announce. If you know a way to get it working, let

[twsocket] SAN SSL certificates

[Fastream Technologies]

Hello,

I wonder how should we support SAN (Subject Alternative Name) certificates
with ICS? These are certificates with multi domains. Are they implicitly
supported?

Re: [twsocket] SSL server and CLient cert.

[Fastream Technologies]

Hello,

If you want SSL, a server certificate is a must. It enables the client to
validate the server's authenticity. If you additionally need the server to
validate the client, then optionally you need a client SSL certificate. Some
of our reverse proxy clients use it since some Microsoft web server
applications require it but most do not need it.

[twsocket] Wiki article writing incentive idea

[Fastream Technologies]

Hello Francois,

After observing your wiki with not much content for so long time, I have
come up with an idea. Why don't you open a "use cases" category where
developers can explain how they use ICS within their projects technically
and more fundemantally why they choose it. In return we should be given the
right to place links to our company web sites. If you look at our history
page at www.iqproxyserver.com/history.php , I have mentioned ICS there but
for technical writings your site is a better fit.

Re: [twsocket] SSL server and CLient cert.

[Fastream Technologies]

Hello again,

ICS and Apache uses the same open source component called OpenSSL as base
for their SSL features. So any certificate works for Apache works for ICS,
that's what I meant.

Self-signed certificates are open man-in-the-middle attacks.

SZ

Re: [twsocket] THttpCli bug with test unit

[Fastream Technologies]

Hello,

I have debugged the issue. It works on older ICS versions but with newer
versions, URL
http://fastream:g...@members.dyndns.org/nic/update?system=dyndns&wildcards=nochg&hostname=abc.dyndns.org&myip=95.15.220.199
does state Connection: close but the server expects the client to close the
connection which confuses ICS.

[twsocket] THttpCli bug with test unit

Hello,

I have come accross an issue that I recall I had made a workaround in the
past but cannot remember what it was. Perhaps it is time this bug is fixed.
The C++ code is at,
http://www.fastream.com/ics/HttpClientTest.rar and after a sync GET to a URL
with no content-length and chunked encoding (connection: close), it does not
call onrequestdone! Checked with Wireshark and the response is returned to
the client. The test URL is dyndns.com (this is actually a part of our
dynamic DNS updater) and it should return "badauth".

I hope you can help.

[twsocket] Zlibhigh compression function with content length and offset

[Fastream Technologies]

Hello,

The function I posted earlier has just been tested and failed due to
ICS/ZLib issues. We offer $120 with Paypal for somebody who could modify ICS
code in an acceptable (by Francois) manner so that the compression function
takes offset and length parameters. This is an urgent job.
