rowland / fb Goto Github PK

I'm running fb (0.7.4) with Ruby 2.0.0-p576 (x64) on a Windows 8 machine. When I attempt to connect to a database, Ruby sefgaults with no obviously useful information.

READ UNCOMMITTED transactions don't seem to work. I get an error Illegal transaction option was specified.

require 'fb'
db = Fb::Database.new(database: "localhost:#{File.expand_path('../db/example.fdb', __FILE__)}")
conn = db.connect rescue db.create.connect

begin
  conn.execute("CREATE TABLE TEST (NAME VARCHAR(20))") if !conn.table_names.include?("TEST")
  conn.transaction 'READ UNCOMMITTED'
  conn.execute("INSERT INTO TEST VALUES (?)", 'Test')
  conn.commit
ensure
  conn.close
end

The tests run against what looks like a demo database (drivertest.fdb). I don't see that in the repo or in my firebird installation, but I'd be interested in seeing if I can get the tests running. Can you add the file to the repo?

Thanks,
Patrick

Hi Rowland, after my first incursion with this gem (and a ruby c extension) I'm thinking a few ways to improve the gem aesthetically speaking to encourage collaboration so it's no so intimidating to newcomers:

• fb.c is too long (3200 LOC), why not separate it by class?
• set on a standard for whitespace: remove tabs and set on 2 or 4 spaces width?
• remove trailing whitespaces
• remove old commented code
• better format for README, also with instructions how to colaborate (or a link maybe)

So, the codebase will remain the same.. what do you think? I can have a pull requests in the near future if you agree.

By the way, are you going to bump version to 0.8 and push to rubygems master?

Something is wrong with fb on my pc. LoadError: 126: �� ������ ��������� ������. - C:/Ruby23/lib/ruby/gems/2.3.0/gems/fb-0.8.0/fb.so
I tried to user different versions of ruby, but it didn't helped.

Hello,

Has some possibility of Fb support ruby 1.9.1?

Thanks

Before this I followed the instructions here: http://www.firebirdsql.org/file/documentation/papers_presentations/html/paper-fb-macosx-install.html

Which led me to download the latest Mac version here:
https://sourceforge.net/projects/firebird/files/

Are there other instructions I need to follow in order to get this installed? Please advise, thank you!

Since it seems that issue #58 seems to be merged I make a new issue here.

I am trying to connect to a firebird 3 and am always getting an error (Firebird error unknown ISC error 335545106) which, after some research seems to be an authentication error. The firebird.log is also telling me, that the auth plugin not supported by network protocol
I have configured the db to use legacy_auth but still nothing changed. Do I have to configure something else as well?

I've been caught by a very strange bug at my production server related to decimal fields:

• Reading values bigger than 20000 (aprox) gets trash.
• The issue only occurs with decimal(18, 5) fields.. but decimal(18, 2) fields work fine, haven't tested others.
• The data is well written and correct at the db, I can check that using isql directly, the problem is when is read by fb.
• I'm pretty sure the bug lurks at the fb gem (isql works fine and fb-activerecord-adapter is bypassed).
• Strange enough I wasn't able to reproduce this bug at my dev machine.. but I've found why: it's a x86_64 architecture, and my production server is x86.
• decimal(18, x) gets stored as 64bit integers, I think that fb is messing the math of the scale in some way that only affects 32bits arquitectures.
• Maybe "static VALUE fb_cursor_fetch(struct FbCursor *fb_cursor)" at fb.c@1961 is the culprit ? Maybe the conditional compilation switched by HAVE_LONG_LONG is related?

How to reproduce (32bit architecture needed):

require 'fb'
include Fb
db = Database.new(:database => "#{File.expand_path(File.dirname(__FILE__))}/test.fdb", :username => 'sysdba', :password => 'masterkey')
conn = db.connect rescue db.create.connect
conn.execute("create table TEST (ID int not null primary key, N decimal(18, 5))") if !conn.table_names.include?("TEST")
conn.execute("delete from TEST")
conn.execute("insert into TEST values (?, ?)", 1, 50000)
puts "50000 = #{conn.query(:hash, "select * from TEST").first['N']} ?"

At my production server I get:
"50000 = 7050.32704 ?"
and at my dev machine of course:
"50000 = 50000.0 ?"

It would be efficient to have a name attribute for the Fb::Cursor object so that we can run such queries :

cnx.execute('select * from table for update with lock') do |cursor|
  cnx.execute("update table set... where current of #{cursor.name}")
end

I'm trying Firebird 3 and in a Select statement if it includes a Boolean column I get the next error:

Specified table includes unsupported datatype (32764) (Fb::Error)

Please add support for the Boolean data type.

Thank tou.

The schema reversal of a rails production database started giving problems, all indexes thata were not unique started being reported as unique. But the development db worked fine.. after some research I was able to track the bug to connection#indexes:

1. RDB$INDICES.RDB$UNIQUE holds the interesting property
2. when FB first creates a not unique index, it fills the value with null, and everything works fine (it get's reported as not unique)
3. but for some reason, after a backup-restore cycle, this value gets changed to '0'
4. this has been reported here: [http://tracker.firebirdsql.org/browse/CORE-933;jsessionid=EBB3F797BE85B7CF5A6E6199ED6BB064?actionOrder=desc] but it's not a bug, just an inconsistency: "in system tables null and '0' it's the same".

fb.c line 2904

unique = RTEST(unique) ? Qtrue : Qfalse;
descending = RTEST(descending) ? Qtrue : Qfalse;

So if according to what I've read online RTEST is the same that "if" for ruby, the problem is that 0 is being evaluated to true: it should test for null or 0.

Maybe this is affecting descending also and other system table tests..

Sorry easy fix but I'm not confident touching c ruby

I am trying to pull down the gem code directly with the bundler and am currently getting the following error:

Updating https://github.com/rowland/fb.git
Fetching source index for http://rubygems.org/
Could not find gem 'fb (>= 0, runtime)' in https://github.com/rowland/fb.git (at master).
Source does not contain any versions of 'fb (>= 0, runtime)'

This seems strange to me because there is a valid .gemspec file

gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'nokogiri'
gem 'fb', :git=>'https://github.com/rowland/fb.git'
group :development,:test do
gem "rspec-rails", "2.4.0"

end

I'm using this gem in production alongside with Sinatra, ActiveRecord and Puma. Puma is running with 2 workers.

My code for database queries is identical to the following snippet:

database_connections =  YAML.load_file('./databases_list.yml')

database_connections.each do |connection_info|
  connection = ActiveRecord::Base.establish_connection(connection_info)
  connection.execute('SELECT * FROM ...')
  # Other SQL queries here
  connection.disconnect!
end

I have a list of identical databases (running on distinct servers) that I have to connect to and collect some data. But I'm suspecting I'm doing something terribly wrong, as when this code gets executed, the ruby interpreter raises a Dropped DB Cursor exception.

Do you have any idea of what can be possibly causing this error?

Hi, is there a way to run Firebird's stored procedures using this gem, please? Thank you.

Might you check?

I added some code to search for the Firebird Root dir from the "FIREBIRD" environment variable and the default registry location before brute forcing the program files tree.

This makes the gem installable with RubyInstaller + DevKit !

As title says we're experiencing weird behaviour when passed parameters do not reach database itself.
I've made some research, but got nothing so far.
Our exec_query method is:

        def exec_query(sql, name = 'SQL', binds = [], prepare: false)
          type_casted_binds = type_casted_binds(binds)

          log(sql, name, binds, type_casted_binds) do
            ActiveSupport::Dependencies.interlock.permit_concurrent_loads do
              result = @connection.execute(sql, *type_casted_binds)
              if result.is_a?(Fb::Cursor)
                fields = result.fields.map(&:name)
                rows = result.fetchall.map do |row|
                  row.map do |col|
                    col.encode('UTF-8', @connection.encoding)
                  rescue StandardError
                    col
                  end
                end
                result.close
                ActiveRecord::Result.new(fields, rows)
              else
                result
              end
            rescue => e
              result.close if result && result.is_a?(Fb::Cursor)
              raise e
            end
          end
        end

Rails correctly passes sql statement and its parameters to connection_execute method:

I have kinda reproducible test case, but I'm not familiar with C or ruby C API. Do you have any ideas what could causes it?

The adapter ignores the default charset, if I use utf8 It should return UTF-8 encoded strings, but It always returns ASCII-8BIT strings.

This is a problem concatenating strings in Ruby, becase UTF-8 and ASCII-8BIT are not compatible, for example this causes an error if the string containts any of the characters á é í ó ú.

"Hello" + data["my_string"]

I need to do this

"Hello" + data["my_string"].force_encoding("UTF-8")

Doing this is tedious, specially in Sinatra applications.

When trying to execute scripts with a COMMIT; statement the method returns "Fb::Connection#commit()" exception

I have an application that runs under Ruby 2.0.0-p648 (x64).
After configuring Devkit (x64), installing Firebird 2.5 (x64):
I successfully install the gem.

But by running the simple test:
require 'fb' include Fb db = Database.new( :database => "localhost:d:/readme.fdb", :username => 'sysdba', :password => 'masterkey') conn = db.connect rescue db.create.connect

I get the following generic error: conn = db.connect ... [BUG] Segmentation fault #38
The error also happens in a clean install of the measured versions.

If I do the same steps however everything on x86 (Ruby 2.0.0-p648 (x86), Devkit (x86), Firebird 2.5 (x86)) the code runs normally.
I've checked in many ways for the correct DLL installed on each version of Firebird.

Today I can't upgrade Ruby as there is a large application running with this specific version.

Any suggestions on how to make it work?
Thank you.

I get this error while trying to install it on Windows 64 with Firebird 2.5.1 64, this is the log using the latest source

Hello,

I have a program, it connects to MySQL and Firebird.
The default database is MySQL
How can i create a migration database using fb?

When migrating code to a new server I found that code which works with 0.7.0 fails with 0.9.0. I tested to make sure it was not a ruby or firebird issue. The insert statement succeeds but attempting to retrieve the expected value from the cursor fails with: " The cursor identified in an OPEN statement is already open."

You can use this function on fb?

http://www.rubydoc.info/gems/mysql2/0.2.6/Mysql2/Client:last_id

Thanks!

hi,

i want to switch from jruby jdbc-firebird adapter to your gem.

first error appears at saving object to database:
@car.save

Fb::Error: A transaction has been already started: begin transaction

thanks for help

Hi Brent,

I tried to build the fb gem using RubyInstaller 1.9.2p136 + DevKit on Windows and the gem build command failed complaining that the PLATFORM const was not declared.

I had to change it to RUBY_PLATFORM to make the gem builder happy.

s.platform = case RUBY_PLATFORM
when /win32/ then Gem::Platform::WIN32
else
Gem::Platform::RUBY
end

FYI, I installed FirebirdSS-2.1.4-18393-x86_64.pkg.zip into /Library/Frameworks/Firebird.framework

I noticed that the install is looking for re.h. I'm not sure if that is supposed to be part of the Firebird install, but the /Library/Frameworks/Firebird.framework/Headers directory only contains:

cd /Library/Frameworks/Firebird.framework/Headers

Any help would be appreciated.

is need fix:

}
}

I have blob field in a table where I store PDFs, there is no problem storing them, but when I retrieve a PDF from then blob field and save it to a file, the PDF file is corrupted, if I do table['pdf_field'].class I get "string", why? it is supposed to be binary.

This is the code to extract the PDF file from the field.

File.open(p_ruta_tmp, "w") do |f|
    f.write(p_adjunto[0]['adjunto_pdf'])
end

If I extract those fileds in C# the fields are extracted fine.

Thanks.

Excited to find this gem, but I'm having trouble getting it to run. I installed version 0.7.4 via 'gem install fb', and it built the native extension without a problem.

When I try to run the README, though, it complains:

$ ruby README 
ruby: symbol lookup error: /home/patrick/.rvm/gems/ruby-2.2.1@fb/gems/fb-0.7.4/fb.so: undefined symbol: isc_attach_database

I think I have the required client installed:

$ ls /usr/lib/libfb*
/usr/lib/libfbclient.so  /usr/lib/libfbclient.so.1  /usr/lib/libfbclient.so.1.5.6  /usr/lib/libfbembed.so  /usr/lib/libfbembed.so.1  /usr/lib/libfbembed.so.1.5.6

... but perhaps not...

I tried building from source and I see this when running extconf.rb:

$ ruby extconf.rb
checking for isc_attach_database() in -lfbclient... no
checking for isc_attach_database() in -lgds... no
creating Makefile

I'm running 2.2.1 in RVM.

Any help would be greatly appreciated. This library will be a huge help to me :)

I'm getting a segfault if I do a query that has no results and then try to #fetch it. Is there a way to safely check if a result exists before doing a #fetch?

Thanks,
Patrick

For example (a result is found):

$ rails runner "p Firebird::Address._connection.execute('select ADDRESS_ID from TBL_ADDRESS where ADDRESS_ID = 1').fetch(:hash)"

{"ADDRESS_ID"=>1}

(no result found, segfault):

$ rails runner "p Firebird:Address._connection.execute('select ADDRESS_ID from TBL_ADDRESS where ADDRESS_ID = 9999').fetch(:hash)" 2>&1 | head -50

Hello!

I'm struggling to install this gem. I have already installed the firebird-devel and firebird-client packages, but despite that, a fatal error: ibase.h: No such file or directory is being thrown during the install process.

Is it possible to point out the absolute path to ibase.h in my host at the gem install moment?

Rowland: Hi, after your last fix about the rounding issue I've looked at little closer at the fb implementation because something got my attention (extracted from fb.c@2039)

static VALUE fb_cursor_fetch(struct FbCursor *fb_cursor)
(...)
case SQL_INT64:
        if (var->sqlscale < 0) {
          ratio = 1;
          for (scnt = 0; scnt > var->sqlscale; scnt--) ratio *= 10;
          dval = (double)*(ISC_INT64*)var->sqldata/ratio;
          val = rb_float_new(dval);
        } else {
          val = LL2NUM(*(ISC_INT64*)var->sqldata);
        }
  break;

FB is handling fixed precision decimals (sqlscale > 0) converting them back to C doubles and ruby floats..! But wait, I said.. at ActiveRecord I'm pretty sure I'm getting back BigDecimals.. that's true, but they are being instantiated from the Floats so the precision lost already happened!

I 've made this simple script to expose the issue:

require 'active_record'
require 'fb'

db = Fb::Database.new(:database => "#{File.expand_path(File.dirname(__FILE__))}/test.fdb", :username => 'sysdba', :password => 'masterkey')
conn = db.connect rescue db.create.connect
conn.execute("create table TESTS (ID int not null primary key, N decimal(18, 2))") if !conn.table_names.include?("TESTS")
conn.execute("delete from TESTS")
conn.execute("insert into TESTS values (?, ?)", 1, BigDecimal.new('91520.65'))
value = conn.query(:hash, "select * from TESTS").first['N']
puts 'fb directly'
puts "91520.65 = #{value}? (class #{value.class})"
puts "but actually.. surprise!! " + "%.13f" % value

CONFIG = <<-EOS
test:
  adapter: fb
  database: test.fdb
  username: sysdba
  password: masterkey
  host: localhost
  create: true
  encoding: UTF-8
EOS

ActiveRecord::Base.configurations = YAML::load(CONFIG)
ActiveRecord::Base.establish_connection('test')
class Test < ActiveRecord::Base
end
puts "\nthrough activerecord-fb-adapter"
value = Test.first.n
puts "91520.65 = #{value}? (class #{value.class})"
puts "\nerror only when displaying..?"
puts "915206500000 = #{(value * BigDecimal('10000000')).to_i} nope..!!"

That output's

fb directly
91520.65 = 91520.65? (class Float)
but actually.. surprise!! 91520.6499999999942

through activerecord-fb-adapter
91520.65 = 91520.64999999999? (class BigDecimal)

error only when displaying..?
915206500000 = 915206499999 nope..

So actually this is what is happening here:

• At first sight it looks like fb is handling the issue correctly, but actually this is an illusion because most decimal numbers don't have an exact binary representation but when they are inspected they are rounded.. so 91520.65 is rounded for displaying, but actually is a floating value like 91520.6499999999942 etc..
• When AR get's the value it says this is a decimal column, so instantiate a BigDecimal with it.. here the precision lost is exposed.
• Most of the time, this didn't make a diference, that's why I haven't noticed this until now.. because the precision lost is small and only happens when you read values from the db (writing is ok).. so for the problem to scale you have to operate a lot on this BigDecimals (and usually calculations like sum are handled directly to SQL). Also when I was displaying this values back to my users through format_currency it rounded them hiding the issue.
• But believe me, this is a serious issue lurking, someone will shot very bad in his foot with this sooner or latter.. mixing floats and money is a recipe for disaster at financial domains.

So the question is.. do you think is possible to, instead of instantiate a Float, to return a BigDecimal there without creating havoc on the user base? I may even try to pull the patch myself..

Something like:

rb_funcall(rb_path2class("BigDecimal"), rb_intern("new"), 1, rb_str_new(str_decimal, 6));

After every select commit transaction is called. Why is that? And how to turn this feature off?

A regression in 0.7.5 (which was meant to be 0.8.0, because it breaks Ruby 1.8.7 compatibility) can cause integer overflows in 32-bit implementations of Ruby. An investigation is in progress.

Hi!
In my Rails 3.2.12 application i need to connect to Firebird server located in local network from server with application.
The next code works well in development mode

require 'fb'
include Fb
db = Database.new(
  :database => Rails.configuration.firebird_url,
  :username => Rails.configuration.firebird_username,
  :password => Rails.configuration.firebird_password,

conn = db.connect rescue db.create.connect

client = conn.query(:hash, 'select * from "SomeTable" where "ID"= ?', id)

But returns nothing (query returns nothing) in production mode.
It also works well in rails console both in production and development.
Maybe some part of Rails refuses connection or data returned by query.
Please, help me to figure out this problem.

I ran gem install fb and the output was:

I am running FirebirdCS-2.5.7-27050-i386 with fb 0.8.0 and Ruby 2.3.0 on macOS 10.12 (Sierra).

I can connect using .Net and Java drivers but not using Ruby driver.

There is no option to use fb embedded, it would be good to have that option for many reasons.

Currently fb only works with firebird 2.5, there is currently firebird 3 and distros like Fedora and Ubuntu are updating their packages to install Firebird 3 and deprecating 2.5 making it hard to install fb with Ruby.

Thanks.

As best I can tell, there is no timeout when establishing a connection. The following script ran for about 4 minutes on my machine:

#!/usr/bin/env ruby
require 'fb'

Fb::Database.new(
  database: 'fakeurl.com:/fake/database/path.fdb',
  username: 'sysdba',
  password: 'masterkey'
).connect

When it finally did exit, this was the error:

$  time ./connection_timeout.rb
./connection_timeout.rb:8:in `connect': Unsuccessful execution caused by a system error that precludes successful execution of subsequent statements (Fb::Error)
Unable to complete network request to host "fakeurl.com".
Failed to establish a connection.
    from ./connection_timeout.rb:8:in `<main>'
./connection_timeout.rb  0.07s user 0.02s system 0% cpu 4:16.76 total

The connection should probably bail after a certain amount of time. Ideally, this amount of time would be configurable in the connection hash. I'm not a C guy, so I'm not sure I'll be of any help.
