Re: [Firebird-net-provider] A way to monitor connection state
It's not? Even if you keep a 1-1 relationship between threads and connections (i.e. use a separate connection per thread)? If you have separate connections for each thread, why bother about thread safety? Thread safe is about using one connection in multiple threads. Yeah, sorry, that's what I thought. I know some DBMSs allow multiple transactions at the same time in one connection, but it's not what you'd call a normal feature...

Re: [Firebird-net-provider] Programs refuse to run with new dll 2.5.0.0 beta
The DPB for embedded on Windows doesn't expect a username and password, Jiri. AFAIK, embedded server will simply ignore it. You're able to login with any username/password. The empty login and password as signal to try trusted auth is taken from standard FB tools. For now the trusted auth isn't done on embedded (I haven't tested whether it works), but I think that (if it works) it must be handled. Because you can have permissions on database objects applied to domain logins. Thus if you don't wanna to fall into trusted auth, you have to specify some username (I think sysdba will be ok ;)). That's the reason why it works like it works right now. That seems backwards to me, though. Shouldn't you have to do something to get it to try trusted auth? I mean, my code for embedded looks basically the same as Paul's, and I would assume that even were trusted auth to be implemented, I wouldn't be using it. I would suggest a new property in FbConnectionStringBuilder to explicitly turn trusted auth on would be the way to go, otherwise it would just use whatever it used before? You don't want to change the behaviour of currently-working code for no good reason, I think. So you'd have to set fbcs.TrustedAuth = true; in order to get trusted auth - whether in embedded or server...

This is what I was trying to avoid. Yet another connection string param. I can understand that desire, but I don't see how you can do it without breaking existing clients (unless you just disabled trusted auth in embedded). Maybe you could make is so that you have to explicitly set the user name to an empty string, as opposed to just not specifying anything? Also, it's not really an *extra* parameter, because you would specify it *instead of* a username/password, if you get my meaning.

I use datasets in my application and have problems when multiple users change data in database. My question is: how do you handle the dataset problem? You mean if user A and user B load the data set and the same time, the user A modifies one row and commits, then user B modifies a different row and commits user B overwrites user A's changes? .NET already has a mechanism to handle that. The steps are, basically: 1. Build and fill a DataSet with data from a data source using a FbDataAdapter. 2. Change the data in individual DataTable objects by adding, updating, or deleting DataRow objects. 3. Call DataSet.GetChanges to create a second DataSet that features only the changes to the data. 4. Call the Update method of the FbDataAdapter, passing the second DataSet as an argument. Check out the documentation for the DataAdapter class (which FbDataAdapter inherits from) for more information.

Re: [Firebird-net-provider] Connection Pooling Options With Firebird

I would suggest you remove the connection pooling stuff from the
connection string. Connection pooling is on by default, and the default
parameters have been chosen to provide the best results in most situations.
The simple code below is similar to what I'm calling to open / close a
connection when needed:
procedure Ttest.Page_Load(sender: System.Object; e: System.EventArgs);
var
conn : FirebirdSql.Data.FirebirdClient.FbConnection;
begin
// TODO: Put user code to initialize the page here
conn := FirebirdSql.Data.FirebirdClient.FbConnection.Create;
conn.ConnectionString :=
System.Configuration.ConfigurationManager.ConnectionStrings['MyConnString'].ToString;
conn.Open;
Response.Write ('Connection openBR');
Response.Write ('Connection Pools Count = ' +
conn.ConnectionPoolsCount.ToString + 'BR');
conn.Close;
Response.Write('Connection closeBR');
Response.Write('Connection Pools Count = ' +
conn.ConnectionPoolsCount.ToString + 'BR');
Assuming you do an actual database call between the open and close, then
yes, that is the correct way to be doing it.

You should never rely on the garbage collection to close database

If you pass CommandBehavior.CloseConnection to the ExecuteReader()

when you call it's IDispose.Dispose method. So you can do something like
this:
using(FbDataReader reader = getReader(blah))

As I understand it, when you implement IQueryable, you've tied all your client code to *that specific implementation*. Whereas with the entities framework, you can simply swap out the entity provider for a different one. It's basically one level higher than IQueryable. That means you can write your code against Firebird (or whatever), and later swap in another ADO.NET data provider without too much trouble. You can even do it dynamically at runtime. Additionally, it allows the IDE to generate all kinds of graphical representations of your data source (which are mapped to entities) so you build up your business data object via a graphical UI, and then use them in your code.

[Firebird-net-provider] patches for 64-bit data provider + embedded (2.1 beta 2)
Hi everyone,
So I was playing around with the data provider and the 64-bit version of
2.1 beta 2 embedded this weekend, and I managed to get it to work.
I've got a .zip containing my changes (as applied to the provider
2.5.0-alpha1) here:
http://codeka.com/tmp/firebird.net-2.5.0-alpha1-64bit-patches.zip
There wasn't a lot of changes required, really, though there is one that
kind of worries me.
The hardest thing for me to figure out was the fact that the XSQLVAR
structures were being offset incorrectly in a 64-bit build. I don't know
if it's due to a bug in the structure packing of the embedded DLL or
what, but I had to change the XsqldaMarshaler.ComputeLength to read:
private int ComputeLength(int n)
{
int length = (Marshal.SizeOf(typeof(XSQLDA)) +
n * Marshal.SizeOf(typeof(XSQLVAR)));
if (IntPtr.Size == 8)
length += 4;
return length;
}
Basically, we need to offset the first XSQLVAR structure by 4 in a
64-bit build.
Other than that, the only other thing I had to change was the
StatusVector stuff in IDbClient so that it's an IntPtr instead of an int.
Now, I've only tested this against my little test app that I linked to
last week, as well as doing a quick test on our own internal app (which
does not make use of many of firebird's features *by far* so there's
plenty of opportunity for other things to be screwed up still :-) but at
least we're part of the way there...
Dean.

Still, might be a fair amount of work there... Works the provider built for 64 bit platform against the 2.1 beta 2 stand alone server or not ?? I believe so.

Can anyone give me some suggestion please? Firebird (nor any DBMS that I know of) does not support specifying a list of parameters like that. Remember the @param is not a simple string-replacement operator -- they are allowed only where actual query parameters are allowed. For example, you *could* do it like this: SELECT * FROM USERS WHERE ROLEID IN (@rid1, @rid2) But then you're obviously limited to specifying exactly two parameters. Generally, however, an IN query is not exactly efficient, so the performance benefits of command parameters is not really there. It's also fairly easy to validate the input string yourself (seeing as you know it's only supposed to be numbers separated by commas).

Issue Type: Improvement
Components: ADO.NET Provider

Priority: Minor
I am proposing that we replace any instances of:

With the following:
IPAddress addr;
if (!IPAddress.Parse(hostname, out addr))
{
addr = Dns.GetHostEntry(hostname).AddressList[0];
}
The call to Dns.GetHostEntry requires a DNS resolve, which can be costly if
there is no reverse DNS set up for the IP and it has also been known to return
different results to the IP you input.

Re: [Firebird-net-provider] Connection problem from Win
The change is, that you're first doing stuff with DNS and else the IP direct. Maybe trying first IP (we can expect, that if somebody provides IP, (s)he's know it and knows what's doing), so we needn't to check anything else. The possible error in fact will occur during connection anyway. That's correct. Also, just to beat this dead horse a little more, here's the result of my test program on one of our servers that has two network cards: C:\temp test 10.1.0.135 Testing: 10.1.0.135 Hostname: gbasmsa1-nelson.dload.live Address: 10.1.0.135 Address: 10.0.1.135 C:\temp test 10.0.1.135 Testing: 10.0.1.135 Hostname: gbasmsa1-nelson.dload.live Address: 10.1.0.135 Address: 10.0.1.135 Notice that in this case it returns the addresses in the same order, regardless of what IP I originally pass to Dns.GetHostEntry. From my testing, this only seems to occur when you enter an IP that resolves to the local host -- if I run the program from a different host, I only get the one result back. It may be a problem with our DNS set up, or something else, but that's clearly not what you would expect! I've added it to JIRA, but it's up to you guys what you want to do with it anyway :-) Dean. - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Yep, but internally. Then you get back your IP (the IP you provided) and maybe some others. But this isn't the problem. He has 2 NICs on client not on server (if I understand). But that has not been my experience: I have seen it return a *different* IP. Also, if you do not have reverse DNS set up for that IP, then you won't get any results at all. For example, here is a MySQL bug related to Dns.GetHostEntry: http://bugs.mysql.com/bug.php?id=26593 I'm not saying this is the problem in this particular case, but I have run into trouble just using Dns.GetHostEntry on an IP address... :-) Dean. - This SF.net email is sponsored by: Splunk Inc.

Re: [Firebird-net-provider] Connection problem from Win 2003 Standard
I've tested this. I provided IP, that definetelly isn't active in my
netwrok and isn't on my DNS. I got result without problems. I can send
you video. :)
Alright. Here is a program that I ran on my computer:
public static void Main(string[] args)
{
string address = args[0];
Console.WriteLine(Testing: {0}, address);
IPHostEntry hostent = Dns.GetHostEntry(address);
Console.WriteLine(Hostname: {0}, hostent.HostName);
foreach(string alias in hostent.Aliases)
{
Console.WriteLine(Alias: {0}, alias);
}
foreach(IPAddress addr in hostent.AddressList)
{
Console.WriteLine(Address: {0}, addr);
}
}
Here is the output for two different addresses:
D:\Projects\TestProject\bin\Debugtest 10.0.0.33
Testing: 10.0.0.33
Hostname: xx
Address: fe80::69eb:837:6a0:5c66%8
Address: fe80::5efe:10.0.0.33%11
Address: 10.0.0.33
D:\Projects\TestProject\bin\Debugtest 123.123.123.123
Testing: 123.123.123.123
Hostname: 123.123.123.123
Address: 123.123.123.123
The first address is my local IP address. Notice how it returned the IPv6
addresses *before* the IPv4 (this is Windows Vista). The second address is
one that does not exist on my network. Not visible here, of course, is the
fact that this address took about 6 seconds to resolve whereas the first
one was practically instant.
Your network may be different, but clearly not all networks are the same as
yours.
Remember, all I'm trying to say here is that you should replace the line:
IPAddress addr = Dns.GetHostEntry(hostname).AddressList[0];
With the following:
IPAddress addr;
if (!IPAddress.Parse(hostname, out addr))
{
addr = Dns.GetHostEntry(hostname).AddressList[0];
}
It's not a big change and it's only useful in certain circumstances, but it
*is* a better solution.

Re: [Firebird-net-provider] Connection problem from Win 2003 Standard
I have 2 NICs in my notebook too. I don't have this problem. And the Dns.GetHostEntry() returns (should) for IP the same IP, that's all. Actually, that's not true. Dns.GetHostEntry() actually queries the DNS server to get the name corresponding to that IP, and then returns all the IP addresses associated with that name. It is quite possible that it can return addresses in a different or unexpected order. Dean. - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Re: [Firebird-net-provider] VISTA Embedded Problem
I'll bet you are right, but what does this mean as more and more folks move to VISTA, will all my users have to have admin rights to run any software that accesses Firebird embedded? As more and more businesses are locking down admin rights, our software opportunities will be more and more limited :( This is something that you'll have to take up on the firebird developer's list, I believe, since it's not really a problem with the .net provider as such. Note that you don't actually need Administrator rights, the Administrator account has Create Global Objects by default (and since Local Security Policy is not affected by UAC, you don't need to Run as Administrator), but you can assign that right to a limited user and things are still quite effective. As I said, though, this is not just a Vista problem: the privilege was introduced in Windows XP SP2. So it would also affect you running as a limited user account in a fast-user switching environment (you can try it out by logging in to Windows XP, then doing Switch User and logging in as a limited user -- you will get the same error). It's just more prevalent in Vista because nobody runs in session 0 any more. Dean. - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

i mean it works whether i write 127.0.0.1:c:\my.fdb or c:\my.fdb , i'm eager why :-) ? Do you have a firebird server running as well? If you specify 127.0.0.1:c:\my.fdb then you'll be connect via the server (the fbembed DLL can act as a regular network client as well) And i also heard, that Vista has problems with local protocol connection to fb, did you (or smbd. else) tested embeded under Vista ? Yes, it works under Vista (I have tried it). I believe the local protocol used to connect to the server is totally different to how fbembed works. The local protocol uses Named Pipes, I believe and because it doesn't - by default - prefix them with Global\ you cannot connect from your logged-on session to the session which the service runs under. Note that this also means that the local protocol would have never worked on a Terminal Server or Windows XP + fast user switching environment, either...

Download Dependency Walker* and open up fbembed.dll in it. Does dependency walker give you any errors? If you're running on 64-bit windows, for example, you need to set your project type to be x86 explicitly, because embedded firebird does not (yet!!) support 64-bit. Actually, I'm not sure the error you're getting is 64-bit related, but at least dependency walker should give you some clue... hopefully :-) i would have to uninstall orcas and reinstall 2005 I'm pretty sure they can be installed side-by-side (though maybe you do have to install 2005 *before* Orcas, I don't know...) * http://www.dependencywalker.com/ Dean. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Firebird-net-provider] unexpected problem with Euro sign
One questions remains, though. If ISO8859_1 is not suitable for that purpose, why have I never been noticing this before? I mean, why do the other drivers/providers translate those bytes correctly to a Euro sign? ISO 8859-1 and WIN-1252 are almost exactly the same, except that where ISO 8859-1 has some control codes, WIN-1252 has a few extra letters (like U+2020 †, etc) -- one of those extra letters is the Euro sign. Many applications, however (especially Windows applications) treat ISO 8859-1 as being synonymous with WIN-1252, so that's probably why it worked in those other cases. .NET is not so lenient, however, and something marked as ISO 8859-1 to .NET will not be able to contain a Euro symbol.

Re: [Firebird-net-provider] Mapping a database char column to
I'm using .Net 1.1, Fb 1.5 and Firebird Net Provider 1.7 maybe it works with new versions? I wouldn't think so, T and F are not recognised by .NET as strings representing true or false (i.e. Convert.ToBoolean(T) or Convert.ToBoolean(F) are what is throwing that exception). You've got three options: 1. Make the column CHAR(5) and store exactly True or False, or 2. Make the column SMALLINT and store 1 or 0, 3. Leave the database as-is, and manually convert the column in the DataTable #1 is a bit silly, given that it needs 5 bytes to store rather than 1. #2 may not be ideal if you don't want to change the database schema. That leaves only #3, I'm afraid. FbDataAdapter is not really suited for what you're trying to do here. It's purpose it basically to create an in-memory copy of the database table that you can modify and then update back in the database. It's not designed to do complex data conversions (that's what an OR mapper is for).

Re: [Firebird-net-provider] Short char field with longer name
Which is exactly correct. It's only confusing to those who don't understand that not all characters/character sets encode characters with single-byte encodings. It's confusing because the n represents a buffer size. Even allocating four bytes you cannot store 1 character because a character is such a confusing word to begin with. Is é a character? What if I store it as U+0065 U+0301? That's two Unicode codepoints for one logical character. The cause of the problem here is not the length of the data stored but that the client is set to expect single-byte encoding (by using character set NONE) I agree that's a problem, however I disagree that the server should be returning four bytes when the UTF-8 encoded value of e (or whatever ASCII character you like) is only one byte long. What I mean is, even if you changed the connection string character set to UTF8, 0x65 0x00 0x00 0x00 represents four UTF-8 characters (that is, U+0065 U+ U+ U+).

Re: [Firebird-net-provider] Short char field with longer name
Is é a character? Yes. And it is a different character from e, ê or è. Obviously, but the character é can be represented by the single Unicode codepoint U+00E9 (aka LATIN SMALL LETTER E WITH ACUTE) or by the sequence U+0065 U+0301 (aka, LATIN SMALL LETTER E, COMBINING ACUTE ACCENT). My point with this example was to show that one character may require more than one codepoint to represent. You could store é in a CHAR(1) if you used the representation U+00E9, however you could not store it as U+0065 U+0301. The point is that saying n represents a count of characters is misleading, What I mean is, even if you changed the connection string character set to UTF8, 0x65 0x00 0x00 0x00 represents four UTF-8 characters (that is, U+0065 U+ U+ U+). According to what, I wonder? According to the definition UTF-8. See http://en.wikipedia.org/wiki/UTF-8 if you need a primer.

Re: [Firebird-net-provider] Big performance gain on Charset.cs
Well, we have run our internal tests, and also the profiler, and changing this code gains 20%, so it doesn't seem to be doing exactly the same. The old code running through the switch several times, and creating an encoding object thousands of times too. Well, I meant the same in terms of actual functionality. The code in Encoding.GetEncoding caches the return value so when you call it again with the same name, it returns the same instance as before. The speed-up you get is from not having to convert from the string name to an integer codepage and doing a hashtable lookup (basically what Encoding.GetEncoding does internall). Depending on the number of times that gets done, the speedup could be significant.

Re: [Firebird-net-provider] Commit or Rollback after select ?
It's a question for me since a long time. If I create a transaction and just do select statements in it, I'm sure that I didn't change anything in the database. I never know wich is best at the end of the transaction commit or rollback ? Or is just don't matter ... In general (that is, in most database servers, not just firebird), the server has to do more work for a rollback than for a commit. So even if you didn't make any changes still COMMIT your transaction in preference to ROLLBACK. Dean. - Take Surveys. Earn Cash.

Re: [Firebird-net-provider] Bug in Parameter Substitution?
A subquery generated by NHibernate caused a database exception. After some debugging, I could track down the problem to the .Net-Provider layer. You could also try replacing the line: cmd.Parameters.Add(@p0, 0); with: cmd.Parameters.AddWithValue(@p0, 0); The reason that new AddWithValue method was added in .NET 2.0 was precisely because of the ambiguity caused between the Add(string, object) and Add(string, *DbType) overloads. If that fixes the problem (I suspect it will), the bug is with NHibernate - it shouldn't be calling the Add(string, object) overload anymore... or, if it needs to work with .NET 1.1 as well, then it should use a different overload of Add().

An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) Firebird embedded on x64 is not supported (on Windows, at least) - yet. You need to specify in your main application's executable that it should be compiled as 32-bit (x86), rather than the default Any CPU. This means you'll be running in WOW64 on 64-bit Windows, but that's usually OK. I hear 64-bit support for Windows is in the works (it already works in Linux, so shouldn't be too much work) and I, too, am eagerly awaiting it ;) Note: this is a firebird *server* issue; the .net provider works fine in 64-bit.

Re: [Firebird-net-provider] Connection string enhancing
Yes, but this will not work with DllImport. It accepts only constant string as param. And using LoadLibrary will work only on Windows, so for Linux/Mono it will be out. You can make it work using Reflection.Emit and dynamically generating the FirebirdSql.Data.Client.Embedded.FbClient class at runtime, with the full path to the fbembed.dll file in the [DllImport] attributes. This would probably be easier than using LoadLibrary directly (and especially GetProcAddress - in fact, is GetProcAddress even callable from C#?) PLUS it would be just as cross-platform as before!

Re: [Firebird-net-provider] Connection string for embedded firebird
What's the complete exception? My guess is that there is some sort of
permissions problem.
Are you using IIS5 or IIS6 (Windows 2000 or Windows Server 2003)?
For IIS5 you need to give the ASPNET account read/write permissions to the
database file. For IIS6 you need to give whatever account your Application
Pool is running as read/write permissions to the file.
Also, re: your last mail. You can run into problems if you have worker
process recycling turned on in IIS6, but IIS5 should be OK (though if you
ever upgrade to IIS6 in the future...)
The problem with worker process recycling is that when IIS6 recycles the
worker process, the old one hangs around while it finishes servicing current
requests. A new worker process is started to service any new requests. So
there is a (admittedly, short) period of time while there will be two
processes running. If the new worker process tries to open the database file
before the old one goes away, you'll get errors.

Personally, I prefer the use of the FbConnectionStringBuilder class, the
following works:
FbConnectionStringBuilder cs = new FbConnectionStringBuilder();
cs.ServerType = FbServerType.Embedded;
cs.Database = fileName;
Calling ToString() on this returns:
Initial Catalog={fileName}; Server Type=Embedded
Notice that you don't need to specify a user name/password - there is not
security in embedded mode. Also, you can use the text of the enumeration for
Server Type (Embedded is more readable than 1)
What is the error that you get? It could be a file system permissions thing.
Also remember that embedded mode acts like super server - meaing you cannot
open the same database file from different processes. This is important if
you're trying to run in embedded on a web farm or something (you basically
can't do it); it also proves problematic in the event of worker process
recycling in IIS6 (in fact, I wouldn't recommend embedded mode at all in a
website).

Re: [Firebird-net-provider] Connection string for embedded firebird
I'm sorry to keep bugging you on this but doesn't super-server lock the database file? If so, doesn't it have the same drawbacks as embedded? But since super server mode is a server - that is, a separate process to IIS - there's no trouble. There's only ever one super-server mode server process, no matter how many clients connect to it. Embedded is like making every client *process* into a super-server. If there's only one client process, there's no problem. But with web sites, that can be a tough thing to guarantee.

Re: [Firebird-net-provider] Does this support the OleDbConnection Class?
ADO is built on top of OLEDB, and neither of those technologies have anything to do with the Firebird .NET provider. ADO and OLEDB are COM-based technologies (and I wouldn't say they were recommended by Microsoft - certainly not for .NET development). The Firebird .NET provider is based off the .NET System.Data architecture, which is better suited to .NET and is a little more flexible as well. You do not NEED to use the Firebird classes (except to create the actual connection) - most actions can be performed via the IDb* interfaces that all System.Data providers implement (so IDbCommand instead of FbCommand, IDataReader instead of FbDataReader, etc). IMHO, though, trying to get database independence using the interfaces is usually not worth it, unless you're writing against multiple database engines right from the start.

Re: [Firebird-net-provider] Caching is possible?
The way its implemented on SQL Server is that the caching infrastructure on the client keeps a connection open to the server, and there's basically a stored procedure that it calls which only returns when there is a change notification on the server. The tricky part is the implementation of the notifications on the server - the client is relatively easy.

Re: [Firebird-net-provider] Batch Select with Firebird provider

Else no, it doesn't make any sence. It makes perfect sense, the exact same query would work as expected (i.e. you'd get three DataTables inside your DataSet) on SQL Server. It would only provide (noticeable) benefit if you're running Firebird in server mode, though. Executing your query like that, rather than three separate command would save you the round-trip to the database (which can be in the order of a few milliseconds). Obviously, though, if you're running an embedded database, there'd be little difference. I don't know if Firebird supports it in either server or embedded mode, though.

Re: [Firebird-net-provider] Firebird on Windows Vista?
That's because firebird is a 32-bit DLL, and your .NET application is
running as a 64-bit process by default. You cannot load 32-bit DLLs into
64-bit processes.
There're two solutions. The simplest is to run your .NET app as a 32-bit
process. This one will work today, and simply requires that you compile your
application as explicitly Win32, rather than Any CPU (by passing the
/p:Win32 command-line option to msbuild, usually).
The other option is that firebird needs to be released as both 32-bit and
64-bit (so that would be two separate DLLs). That's out of scope of the .NET
provider mailing list, though... hopefully one day, because I'd like to see
that one, too :)
Note: This only applies to firebird embedded, where the DLL is loaded
in-process. The server version is different.
Dean.

Re: [Firebird-net-provider] Transaction
Even were it possible to do it the way you've written, I would avoid doing it like that anyway. The reason is that because the TableAdapter calls will create one connection each to the database, the TransactionScope call will promote the transaction from the location transaction manager to MS DTC, which would be incur a pretty hefty performance penalty. All in all, the transaction support for TableAdapters are pretty lame.
