Subject: [Win32utils-devel] Converting rb_protect + ruby_stop to pure Ruby
Message-ID: <4456A523.6020803@gmail.com>

Hi,

Within process.c, in the fork method, there's this bit of code:

if(rb_block_given_p()){
    int status;
    rb_protect(rb_yield, Qundef, &status);
    ruby_stop(status);
}


I translated that as this:

if block_given?
    status = 0
    begin
       yield
    rescue Exception
       status = -1 # Any non-zero result is failure
    end
    exit(status)
end

Is there a way to get the actual status? The $? global isn't set at this 
point so that doesn't seem to be an option.  Or is this a reasonable 
default?

This isn't crucial but I thought I'd ask.

Thanks,

Dan

Here is rb_protect for ruby

def rb_protect
  begin
    yield
  ensure
    return
  end
end

rb_protect { return }
puts 'return stopped'

rb_protect { exit(1) }
puts 'exit stopped'

rb_protect { raise "STOP ME!" }
puts 'raise stopped'

rb_protect { throw(:jump) }
puts 'throw stopped'

Subject: [Win32utils-devel] Pure ruby win32-process now in CVS
Message-ID: <4456E4BB.3070309@gmail.com>

Hi all,

I've committed what I think is a complete version of win32-process in 
pure Ruby.  The new version is in the toplevel CVS directory.  You'll 
need to grab the latest windows-pr from CVS as well.

If there are any errors, or any comments that are incorrect, please let 
me know.  Otherwise, I'm planning on a release this weekend.

Thanks,

Dan

Subject: [Win32utils-devel] Problem with the new version of win32-process
Message-ID: <445D6EE8.1090003@gmail.com>

Hi all,

Well, I've messed something up in the pure Ruby Process.fork method.  If 
you run the test_fork_waitpid.rb file (in CVS), you'll see this error:

c:/ruby/lib/ruby/site_ruby/1.8/windows/process.rb:132:in `call': can't 
convert false into Integer (TypeError)
         from c:/ruby/lib/ruby/site_ruby/1.8/windows/process.rb:132:in 
`OpenProcess'
         from 
C:/eclipse/workspace/win32-process/lib/win32/process.rb:67:in `waitpid2'
         from C:/eclipse/workspace/win32-process/examples/test_fork.rb:46

Which means it's returning false instead of the pid.  Any ideas?

Thanks,

Dan

PS - To run this you'll need the latest windows-pr from CVS.

The error is due to static variable "i" is not ported correctly to ruby.

Message-ID: <71166b3b0605121015w59fbb8e6oeb8397145542c971@mail.gmail.com>

Hello, I've been trying to use the PureRuby win32 process gem.

This is my child.rb file:

# child.rb

puts "child process #{Process.pid} started at #{Dir.getwd}"

trap("INT") {
  puts "SIGINT signal received."
  exit(1)
}

trap("TERM") {
  puts "TERM signal received."
  exit(1)
}

trap("KILL") {
  puts "KILL signal received."
  exit(1)
}

while 1
  puts "in loop"
  sleep 5
end

====

now, from a irb console I tried the following:

irb(main):001:0> require 'win32/process'
=> true
irb(main):002:0> Process.kill("SIGBRK", 3380)
NameError: uninitialized constant Process::CTRL_BRK_EVENT
        from C:/Ruby/lib/ruby/gems/1.8/gems/win32-process-0.4.0-mswin32/lib/win32/process.rb:156:in
`kill'
        from C:/Ruby/lib/ruby/gems/1.8/gems/win32-process-0.4.0-mswin32/lib/win32/process.rb:124:in
`kill'
        from (irb):2
irb(main):003:0>

====

When calling SIGINT it didn't return anything:
irb(main):003:0> Process.kill("SIGINT", 3380)
=> []

It only work when doing SIGKILL, something isn't graceful for the child process.


Diggin a bit, GenerateConsoleCtrlEvent always return 0, but if you
check GetLastError, was 87: Error: 87
The parameter is incorrect.

I do the same call from FreeBASIC to check it, passed the right PID
form the running ruby process, and that was the result.

According to MSDN docs, you only could send the
GenerateConsoleCtrlEvent to descent process created with the
CREATE_NEW_PROCESS_GROUP

Please see the documentation here:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/generateconsolectrlevent.asp
"Send a specified signal to a console process group that shares the
console associated with the calling process."

So there isn't a functional way to send a INT or BRK signal from other
process already created, only the ones attached to the current console
and created with CREATE_NEW_PROCESS_GROUP

Couldn't find a workaround, Dan?

I don't know that I would call it a bug.  Somebody is logging way to 
much information. ;)

Alright, I'll increase MAX_STRINGS to 128.

Hi all,

I've forwarded this from the Mongrel mailing list to see if anyone has
any thoughts.  In summary, Luis is hitting broken pipe errors on
occasion when he tries to stop a service.  In a later email Luis
mentions that simply ignoring them might not always be the best idea,
since sometimes the service seems to no longer respond, even though it
still appears to be running fine.

Thank you Zed,

Again, I decide to do this against my health (my fiance will kill me for
doing this on Sunday), anyway:

* Revert to my last december xp installation image (thank you Acronis!).
* Used a clean Ruby 1.8.4 with readline, iconv and zlib compiled locally
(no the One Click Installer).

These are the gems I installed to test Rails 1.0.0: actionmailer (1.1.5)
actionpack (1.11.2) actionwebservice (1.0.0) activerecord (1.13.2)
activesupport (1.2.5) mongrel (0.3.8) rails (1.0.0) rake (0.7.1) sources
(0.0.1) sqlite3-ruby (1.1.0) win32-service (0.5.0)

* Created a empty rails 1.0.0 app name myservice.

* Checked it worked with webrick, and mongrel_rails start and got this
information from index.html:
Ruby version                 1.8.4 (i386-mswin32)
RubyGems version             0.8.11
Rails version                1.0.0
Active Record version        1.13.2
Action Pack version          1.11.2
Action Web Service version   1.0.0
Action Mailer version        1.1.5
Active Support version       1.2.5
Application root             D:/Programming/Sources/myservice
Environment                  development
Database adapter             sqlite3

So far, that was OK.

* Installed 'myservice' using mongrel_rails_service:
mongrel_rails_service -n myservice -e development (force the development
environment instead of production as default)

* Started the service, after 10 seconds, service was ready, checked and
compared with previous output, was ok.

* Stopped the service using mongrel_rails_service stop, it stopped just
fine.

Before I jump into conclusion, done a new start & stop round, this time
with a broken pipe error.

Conclusion: something don't work the same way twice.

To probe that I was doing something wrong (which most of the times that
is correct), I created the simple http_service.rb attached to this
message.

It only create a Simple Handler and a DirHandler of the local folder,
always listening in port 3000.

So far, tested against 0.3.8 and 0.3.12.4 of mongrel, functionality was
ok (no problem pipe here).

I changed a lot of the "concept" on how the services work in this
script, so I need help from all the windows users on the list.

Please download the script, put in some folder, and run:
>ruby http_service.rb install
>ruby http_service.rb start
Browse to http://localhost:3000
Check it worked, then stop the service:
>ruby http_service.rb stop
(please check if it report errors or not).
Run with remove command to remove the service from your machine.

Reply to this post with your environment:
>ruby -v
>ver (windows version) Ex: Microsoft Windows XP [Version 5.1.2600]
Against which version of Mongrel you tested it.

I have found that the lack of locking in the debugging methods causes
the broken pipe errors.

I'll find workaround (maybe add logging to eventlog of win32),
suggestions are welcome.

Thank you guys for the time you spend on this, I really appreciate it.

Based on this progress, I'll rewrite the new mongrel_service script to
fix this and will try.

Please, anyone with problems, reply this so we could get these fixed in
the next release.

Later,

Whoops, I'll fix that in the next release.  Just need to include the

Yes, I already know that.  It's documented in the README.

I'm certainly open to suggestions.  How does Ruby's trap("INT") work on
Windows, for example?

Subject: [Win32utils-devel] Need a little help with the pure Ruby
	win32-eventlog
Message-ID: <446A8BBE.70909@gmail.com>

Hi all,

I'm working on the EventLog#read method for the pure Ruby version of 
win32-eventlog, but I'm stuck on the get_description private method.

Here are the problems:

* I don't think I'm advancing the EVENTLOGRECORD properly between 
iterations.  Take a look at the end of the "while dwread > 0" loop.  I 
get some records, but not all of them.

* I'm not sure how to properly populate or pack/unpack the va_list, 
which is later passed to the FormatMessage() function.

Please take a look.

Thanks,

Dan

Thanks.  That mostly seems to work.  However, I'm hitting a segfault
after a few records.  As far as I can tell this happens when +buf+ is
empty, but I'm not positive that's the culprit.

I also noticed that FormatMessage's parameter list is defined as
'LPLLPLP' in error.rb (from windows-pr).  Thinking that might be the
culprit I tried changing the second param to 'L', but that didn't seem
to have any effect.

Any ideas?

Dan

Here's some more info.  Using the C version of win32-eventlog I can see
the record in question looks like this:

#<struct Struct::EventLogStruct record_number=12302, time_generated=Sat
Mar 18 23:13:43 MST 2006, ti
me_written=Sat Mar 18 23:13:43 MST 2006, event_id=11203,
event_type="error", category=0, source="Sms
Client", computer="CO3840GDJBERGEX", user=nil, description="Software

d not locate the scan component of the specified software update
inventory tool.  The scan component
 advertisement might not have run on the client
computer.\r\n\r\nPossible cause: Incorrect package a
nd program name in the Scan.ini file.\r\nSolution:  Verify that the

ed in the scan.ini file are correct.\r\n\r\nPossible cause: Scan

r\nSolution: Specify that the scan component is run in a program

The description length is 664, so we should have enough buffer space.
Hm...looking at the records that precede it, this appears to be the
first description that contains "\r\n" in it.

In other news I don't think the user code is right.  The pure Ruby
version returns 'djberge' for the user instead of nil as it should.

HTH,

Dan

Ack.  Thanks.

Ok, I applied that patch but I'm still hitting a segfault, though after 
a much greater number of reads.  The record it's segfaulting on has this 
in the description:

wuauclt (364) The database engine 5.01.2600.2180 started.

I had to manually edit the file, as I couldn't get the patch utility to 
work properly.  So, it's possible I mistyped something, but I'm not 
seeing anything.

If that's not enough info let me know and I'll attach a copy of the

Subject: [Win32utils-devel] EventLog#tail is broken
Message-ID: <446E7BFF.4060209@gmail.com>

I just discovered something awful.  The EventLog#tail method does not 
work the way I thought it did.  Instead of picking up new events as 
they're added, it's really just iterating backwards through the current 
event log backwards.

Look at this sample below.  The first record is correct.  Then another 
event happens, but instead of the latest record, I get an *earlier* 
record.  Thinking about the flags that are set, EVENTLOG_BACKWARDS_READ 
| EVENTLOG_SEQUENTIAL_READ in the read_last_event() function, it makes 
sense.  It will read backwards sequentially.

UGH.

So, what's the solution?  Just start at the offset returned by 
GetNumberOfEventLogRecords() and use EVENTLOG_FORWARDS_READ | 
EVENTLOG_SEEK_READ instead?

Was it always like this and no one noticed?  Did I goof a commit 
somewhere?  Or are things actually working and I'm panicked for no reason?

Subject: [Win32utils-devel] EventLog#tail followup
Message-ID: <446E83A9.10700@gmail.com>

The solution I see is something like this:

* Set a @last instance variable in the constructor.

* In the read_last_record function, check to see if @last is nil.  If it 
is nil, then it's our first read.  Use the current approach, and set 
@last to the record number.

* If @last isn't nil, use EVENTLOG_FORWARDS_READ | EVENTLOG_SEEK_READ 
flags instead, and use @last + 1 as the offset.

I tested this in the pure Ruby version and it seems to work fine.

Sound good?

That sounds reasonable.

I searched some utilities of tail for event log.

Subject: [Win32utils-devel] Possible problems with EventLog#write
Message-ID: <446FC55C.2030204@gmail.com>

Hi,

I've got EventLog#write and EventLog.add_event_source methods done. 
Well, I *think* they're done, but I can't get the data (text) to work 
properly, and I'm not sure if it's a bug in my .mc file, the 
add_event_source method, the write method, or just a goof in my test file.

The source, category and event id seem to be ok.  However, the 
description always comes back with:

The description for Event ID ( 3 ) in Source ( foo ) cannot be found. 
The local computer may not have the necessary registry information or 
message DLL files to display messages from a remote computer. You may be 
able to use the /AUXSOURCE= flag to retrieve this description; see Help 
and Support for details. The following information is part of the event: 
test.

Anyway, here's the .mc file (which I took from the tutorial.txt file) 
and the test file:

; foo.mc
MessageId=0x1
SymbolicName=CATEGORY_ERROR
Language=English
error
.

MessageId=0x2
SymbolicName=CATEGORY_WARNING
Language=English
warning
.

MessageId=0x3
Severity=Error
SymbolicName=FOO_ERROR
Language=English
Error: %1
.

# add.rb
dll_file = Dir.pwd + '/foo.dll'
EventLog.add_event_source(
    "key_name"              => "foo",
    "category_count"        => 2,
    "event_message_file"    => dll_file,
    "category_message_file" => dll_file
)

# test.rb
require 'win32/eventlog'
include Win32

log = EventLog.open

log.write(
    :source     => 'foo',
    :data       => 'test',
    :category   => 0x2,
    :event_id   => 0x3,
    :event_type => EventLog::WARN
)

log.close

I also made sure that it wasn't a path separator issue by doing a 
String#tr in the add_event_source, but that didn't seem to matter.

Also, I'm not sure that doing File.expand_path on the dll name within 
add_event_source is a good idea - I just tossed that in there for now, 
but I'm curious what others think.

Thanks,

Dan

event_id is defined in the mc.h

Look at the mc.h :

#define CATEGORY_ERROR                   0x00000001L

#define CATEGORY_WARNING                 0x00000002L

#define FOO_ERROR                        0xC0000003L

You must call with event_id value 0xC0000003 instead of 0x3.

But it raises error
test.rb:7:in `write': bignum too big to convert into `long' (RangeError)
        from test.rb:7

It is another problem.

And tail method raises insufficient resource error after reading six
event log messages.

gem, 0.3.13). Now the service part works better.

Still, a few things must be worked to get rails 100% in this env.

I also commented into the file a few things about how service work:

You cannot do file operations (like openning a file and logging into
it) inside service_stop, or actually stopping the listeners threads
user by mongrel make the service hang and report an error.

Found that the rb_funcall() to service_stop (if defined) is done
previously to setting the service state to SERVICE_STOP_PENDING, a
thing that sometimes make the service manager think the service just
crashed.

So far, tested in Windows XP SP2 without any kind of problems (runned
50 start/serve/stop cycles).

Any feedback on this will be helpful, so I attached a Rakefile that
should be used to perform the same test cycles I have done here.

(You will need ApacheBench or replace the worker definitin with
something that could give some load the the mongrel service).

When it finish (or report errors) please mail me the service and
stress log files.

Thanks in advance for the time everyone take on this.

I take it Win32API.c would have to be modified to use ULL2NUM. :(

Confirmed.  I tried wrapping the WaitForSingleObject() function in its 
own thread and/or calling GC.start but that didn't seem to help.  Any ideas?

One workaround is open event log every time like this:

      def notify_change(&block)
         @handle = OpenEventLog(@server, @source)
         unless block_given?
            raise EventLogError, 'block missing for notify_change()'
         end
         event = CreateEvent(0, 0, 0, 0)
         unless NotifyChangeEventLog(@handle, event)
            error = 'NotifyChangeEventLog() failed: ' + get_last_error
            raise EventLogError, error
         end
         wait_result = WaitForSingleObject(event, INFINITE)
         CloseHandle(event)

         if wait_result == WAIT_FAILED
            error = 'WaitForSingleObject() failed: ' + get_last_error
            raise EventLogError, error
         else
            last = read_last_event
            block.call(last)
         end
         CloseEventLog(@handle)
         self
      end

The other is GetNumberOfEventLogRecords instead of NotifyChangeEventLog

For some reason this didn't work right.  It would start returning empty 
structs if too many events happened too quickly.

> The other is GetNumberOfEventLogRecords instead of NotifyChangeEventLog
> refer to http://support.microsoft.com/kb/q245609/

The problem with that approach is that, according to other docs I've 
read, the record numbers can get reused.  That leads me to believe that 
GetNumberOfEventLogRecords() would not necessarily correspond to the 
last record number.

However, I took that general idea and came up with this solution:

# Remove references to the @last instance variable first
def tail(frequency=5)
    unless block_given?
       raise EventLogError, 'block missing for tail()'
    end

    old_total = total_records()
    flags     = FORWARDS_READ | SEEK_READ
    rec_num   = read_last_event.record_number

    while true
       new_total = total_records()
       if new_total != old_total
          read(flags, rec_num).each{ |log| yield log }
          old_total = new_total
          rec_num   = read_last_event.record_number
       end
       sleep frequency
    end
end

I tail'd the Security log (where I could force lots of log entries by 
doing some random things with user accounts) and it handled it just fine.

If you see any problems with this approach please let me know. 
Otherwise, I'm going to commit it later this week (along with updated docs).

However, that still leaves us with the bigint/long issue.

Many thanks,

Dan

The bigint/long issue is only in c version of eventlog.
The source  eventlog.c line #711
  dwEventID = NUM2INT(v_event_id);
should be
  dwEventID = NUM2ULONG(v_event_id);

Pure ruby version works fine.

Subject: [Win32utils-devel] win32/service... still with problems.
Message-ID: <71166b3b0605220900n1556e6a2wac8210657aa170d5@mail.gmail.com>

Hello list,

In my quest to get Mongrel working as service for win32, found some
problems with win32/service that make it impossible to solve.

Attached is the simplest service script I could do with ruby, which
depends on win32/service.

I found that doing anything complex in service_stop (killing threads,
doing file handling, even sleeping for 0.25 seconds). crash the
service with backtraces (of the service) like this:

dead_service.rb:119:in `service_main': uninitialized constant RUNNING
(NameError)
	from U:/Programming/Sources/ruby/try/dead_service.rb:131

Just commenting the sleep command solves that problem, but leaves
other issues there... like the impossible task of killing running
threads (from a ThreadGroup, as example).

Also, removing the while state == RUNNING loop solves the sleep and
file handling issues, but still exist problems with already running
threads that must be killed/stopped.

Or: I'm doing something wrong (in which case please enlighten me) or
there is something wrong on how the threading model is implemented?
(and the mix of C threads with ruby threads).

Thanks in advance for your time,

Regards,

Where does this backtrace go?  I don't see anything like that when I
tail the log file:

2006-05-22 10:38:48 - ** Dead Simple Service starting...
2006-05-22 10:38:50 - ** Done initialization.
2006-05-22 10:38:50 - Entering Service Main
do nothing!

I have no idea why you're seeing that error.  I don't see it.

There are a couple of issues with your script (which may actually be
issues with our sample script).  You should re-raise exceptions or exit
when one of the commands fails.  For example:

rescue Win32::ServiceError => err
   puts "There was a problem installing the service:"
   puts err
end

Should be:

rescue Win32::ServiceError => err
   puts "There was a problem installing the service:"
   puts err
   raise
end

Otherwise, you'll be dropping into a later part of the script, which is
probably not what you want.

I think one thing you'll want to avoid is having a Daemon calling
methods outside of itself, as you're doing with the 'log' method there,
which may be the source of the problem.  Although the example we ship
with the win32-service package mixes the command line stuff with the
actual Daemon code, in practice I separate the actual Daemon class and
the controller script into separate files.  It's a good sanity preserver
I've found.

Actually, after the do nothing! you should see "Leaving Service Main",
which don't happen (don't see why in your setup don't, but here it do,
winxp).

The command part don't affect the Daemon part, both are discarted by
the ARGV[0] and the ENV["HOMEDRIVE"]!=nil

Anyway, followed your suggestions (split the ctrl and the daemon),
with the same result:

2006-05-22 14:19:50 - ** Dead Simple Service starting...
2006-05-22 14:19:52 - ** Done initialization.
2006-05-22 14:19:52 - Entering Service Main
2006-05-22 14:20:00 - Stop Signal received.
do nothing!

Removing the call to the outside function (donothing) solved the
uninitialized constant problem, but the "Leaving Service Main" never
shows, so looks like was terminated previously (no safe cleanup).

Started and stopped the service 2 times, the first left on
service_stop, without cleanup/correct exit of service_main.

The second time left ok, exiting the loop.

Is a 50-50 chance of success with this?

I didn't see it because your 'log' method was defined outside of your
daemon class.  In fact, your script works just fine once you move those
methods within the Daemon class itself.  Attached is the script I'm
using.  Here was the output:

2006-05-22 11:58:09 - ** Dead Simple Service starting...

2006-05-22 11:58:11 - ** Done initialization.

2006-05-22 11:58:11 - Entering Service Main
do nothing!

2006-05-22 11:58:49 - Leaving Service Main

(I added some spaces there since Outlook is joining them into a single
string for some reason).

Hope that helps.

Daniel, you tried more than 1 start/stop cycles?

In the first run, everything worked ok, but several tries after it,
showed that it works "sometimes" and other don't. (no matter if you
left the service running for 1 second or 10 minutes)

Even with these modifications, not always work.

I find useless the service_stop method... sometimes it work, other
don't. Moving the cleanup code from it to the service_main method
(after the loop) also not always work, if the method is in the wrong
point in time (like not evaluating state == RUNNING in that exact
moment), the thread that runs service_main get terminated by the
service.so

If you see the attached version, service_stop will try to raise the
Interrupt exception so the runner thread gets terminated.

that won't happen...

if you move these 2 lines to service_main and comment service_stop, it
will work.

But if you add code that need more time to of execution, the thread
will get terminated:

	def service_main
		log "Entering Service Main"
		
		while state == RUNNING
			sleep 1
		end

		log "Exiting main loop."
		@runner.raise Interrupt

		# slower cleanup...
		sleep 3

		log "Leaving Service Main"
	end


"Leaving Service Main" will never show up in the log, nor will wait 3 seconds.

Maybe I don't get it, but I created a framework for service in
FreeBASIC and also C++, with custom options for the events (onInit,
Main, onStop, onShutdown).

And these worked ok, but found that service.c:Service_Ctrl first
execute the associated method with the EventArray and then set the
service in a PENDING state, which 2 microseconds later get terminated
by the evaluation of the controlcode and the set of StopEvent...

So: slow code in service_stop make Service Manager think your service
hang. Evaluating state in service_main is useless because you need the
right timming (or luck) to evalaute it when was set, lucky enough
don't get killed by the StopEvent raised...

I'm getting it wrong?

Please excuse my poor english (I try harder to express clearly what is
happening) but english is not my native/natural language.

Yes.  I ran a series of start/stops as fast as my little fingers would
let me.  No problem.

When you say it didn't work, do you mean that the the service_main or
service_stop hooks weren't called?  Or some other error?

<snip>

Ok, I see the same behavior you mention - the service_stop handler
doesn't get executed for some reason.  I think we're back to the thread
issues that Heesob mentioned in a previous post about this.

Heesob, care to weigh in?

the service_stop hook is called, but the code in there is no executed,
to the point the service stop responding and service manager report it
that the pipe has ended or an exception ocurred.

I didn't get the Heesob reply about this, maybe thats why I keep
asking the same :-P

On my freebasic (please, don't think freebasic as old basica, is more
powerful than that, closer to c, but with basic syntax).

Anyway, on my framework, I solved this problem executing my Main
function (which will be service_main in the ruby side) in another
thread and wait for it to terminate until I destroy the events.

Also, wouldn't be more correct report to the service manager that
SERVICE_STOP_PENDING (is stopping) before calling service_stop? in
service.c:78-83 thre is executed from EventHookHash prior reporting
the Service Manager that we received the stop signal and we are
stopping.

In service.c:114, dwControlCode is evaluated after setting the
ServiceState, and if it was CONTROL_STOP,  we set the Stop event,
something that exit service_main prematurely.

I don't think service.c could be implemented as pure ruby (due
required native threads)... or not?

Please excuse my english (again), I try to explain better I could, but
is not easy due: complexity of the topic, and the self-learned nature
of the language.

I repeat the last answer.

As you know,the win32-service is multithreaded application.
But, Ruby's sleep or select is not compatible with the Thread of Windows.
While executing sleep or select in ruby code,the other thread cannot
do anything.

To workaround this stopping problem,

1. Use loop of short sleep insthead of long sleep.
ex) 10.times { sleep 1 } instead of sleep 10

2. Use nonblocking IO and socket.

I tried but it would't work for now.

The workaround of stopping problem for now is separate service control
process and working process.
In service_main, use system,fork or something create another ruby
program for working process and send kill to it when stop requested.

Understand that, but wanted to "remark" that anything that take more
than 1 seconds to cleanup in service_main get terminated, no matter if
service_main finished or not.

That will create 2 ruby process, one for the service (which will
depend of svchost.exe) and a child process...

If I send a kill signal, the child process will not cleanup properly,
something we must avoid in a good coded application.

For that approach, using srvany uses less memory than another ruby
process... (just loading the service.so and no other things we use 6MB
of memory).

Anyway, long live to the threading model of Ruby! (better yet, hate
Windows Threads).

Another workaround will be create a native (compiled) exe that
redirect stdin/stdout of the childprocess and execute the Cntrl-C to
finish it properly. I could do it with 30k exe and less than 1.5mb
footprint.

Ok, I'm going to get it out sometime in the next few days.  I got a
bunch of the preliminary work out of the way last night, but I need to
put out the next release of windows-pr first.

You're right, thank you.  Well, I guess we won't have to worry about
that any more. :)

Thanks for you time and help.

Summary: Add UNC support to file / dir

Initial Comment:
I'd like to see win32 support for UNC's on the file management level, i.e. FileUtils for Windows
Enable UNC support for the following (with recursive options please)

directory delete
file delete
file copy
directory copy
file move
directory move

Another option would be to add a 'map to driveletter' method (as once done, the existing FileUtils module works OK.)

Not sure is this should be a win32 request or a FileUtils request??

Message:
I'm inclined to say this should go in FileUtils.  Unfortunately, it would probably never get added.  I recommend submitting a patch on ruby-core.  If they reject it, we'll add custom File.copy and File.move methods into win32-file.

Sorry for the long delay in responding here.  I wanted to get win32-file-stat and win32-file out the door before I considered this.

I do check for GetProcessId in the extconf.rb file.  You must be using the precompiled binary on Win2k or NT.  You'll have to build it from source.

Hi,

What's your OS?
GetProcessId function requires Windows Vista or Windows XP SP1.
For the OS not support GetProcessId, some modification on extconf.rb is required.

Subject: [Win32utils-devel] win32-dir, unicode
Message-ID: <447683A1.3030009@gmail.com>

Hi,

I've got a preliminary version of the pure Ruby version of win32-dir in 
CVS.  However, I was hoping to work out the Unicode issue.  Run this:

from = "C:\\test"
to = "?????"
Dir.mkdir(from) unless File.exists?(from)
Dir.create_junction(to, from)

It works, but my explorer (and dos) window shows the name garbled.  I 
don't think it's a font encoding issue within Explorer, since I can 
create a folder called "?????" manually within Explorer and it looks 
correct.

Any ideas?

Dan

How about some modification of create_function method like this:
  def self.create_junction(to, from,unicode=false)      # Normalize the paths      to.tr!('/', "\\")      from.tr!('/', "\\")

      # You can create a junction to a directory that already exists, so      # long as it's empty.
if unicode      rv = CreateDirectoryW(to_path, 0)      if rv == 0 && rv != ERROR_ALREADY_EXISTS         raise StandardError, 'CreateDirectory() failed: ' + get_last_error      end
      handle = CreateFileW(         to_path,         GENERIC_READ | GENERIC_WRITE,         0,         0,         OPEN_EXISTING,         FILE_FLAG_OPEN_REPARSE_POINT | FILE_FLAG_BACKUP_SEMANTICS,         0      )else      rv = CreateDirectory(to_path, 0)      if rv == 0 && rv != ERROR_ALREADY_EXISTS         raise StandardError, 'CreateDirectory() failed: ' + get_last_error      end
      handle = CreateFile(         to_path,         GENERIC_READ | GENERIC_WRITE,         0,         0,         OPEN_EXISTING,         FILE_FLAG_OPEN_REPARSE_POINT | FILE_FLAG_BACKUP_SEMANTICS,         0      )end...end

Hi Heesob,

That came through as a single line for some reason...

Anyway, I modified the approach somewhat.  Instead of adding a 'unicode' 
flag, I altered the windows-pr package to wrap methods like this:

def CreateDirectory(path, attributes)
    if $KCODE != 'NONE'
       CreateDirectoryW.call(path, attributes) != 0
    else
       CreateDirectory.call(path, attributes) != 0
    end
end

Within dir.rb, I did this:

if $KCODE != 'NONE'
    to_path = to_path.split("\0\0").first
else
    to_path = to_path.split(0.chr).first
end

However, after making those changes I got this:

dir.rb:123:in `create_junction': DeviceIoControl() failed: The data 
present in the reparse point buffer is invalid. (RuntimeError).

Does rdb need to be packed differently?

BTW, I also tinkered with the idea of using IsTextUnicode():

def CreateDirectory(path, attributes)
    if IsTextUnicode(path, path.size, 0)
       CreateDirectoryW.call(path, attributes) != 0
    else
       CreateDirectory.call(path, attributes) != 0
    end
end

But this didn't seem to handle UCS-2, i.e it worked for 
"\x95\x03\xBB\x03\xBB\x03\xAC\x03\xC3\x03\0\0" but not "?????".  I 
imagine it's also slower.

Regards,

Dan

I> imagine it's also slower.>> Regards,>> Dan> _______________________________________________> win32utils-devel mailing list> win32utils-devel at rubyforge.org> http://rubyforge.org/mailman/listinfo/win32utils-develI have managed to succeed in creating junction with create_junction method.
First modify multi_to_wide and wide_to_multi to support UTF8 and Ansi string.For english users, UTF8 encoding is sufficient but other languageusers like Korean, both UTF8 and Ansi are required.
     def multi_to_wide(str)         cp = ($KCODE == 'UTF8') ? CP_UTF8 : CP_ACP         buf = 0.chr * 260         int = MultiByteToWideChar(cp, 0, str, -1, buf, buf.size)         if int > 0            buf[0, int*2]         else            str         end      end
    def wide_to_multi(str)         cp = ($KCODE == 'UTF8') ? CP_UTF8 : CP_ACP         buf = 0.chr * 260         int = WideCharToMultiByte(cp, 0, str, -1, buf, buf.size, 0, 0)
         if int > 0            buf[0, int]         else            str         end      end
Second, modify create_junction method like this:

  def self.create_junction(to, from)      # Normalize the paths      to.tr!('/', "\\")      from.tr!('/', "\\")
      to_path    = 0.chr * 260      from_path  = 0.chr * 260      buf_target = 0.chr * 260
      from = multi_to_wide(from)      to = multi_to_wide(to)      if GetFullPathNameW.call(from, from_path.size, from_path, 0) == 0         raise StandardError, 'GetFullPathName() failed: ' + get_last_error      end
      if GetFullPathNameW.call(to, to_path.size, to_path, 0) == 0         raise StandardError, 'GetFullPathName() failed: ' + get_last_error      end
	to_path = to_path.strip+"\0\0\0"	from_path = from_path.strip+"\0\0\0"
      # You can create a junction to a directory that already exists, so      # long as it's empty.
      rv = CreateDirectoryW.call(to_path, 0)      if rv == 0 && GetLastError.call != ERROR_ALREADY_EXISTS         raise StandardError, 'CreateDirectory() failed: ' + get_last_error      end
      handle = CreateFileW.call(         to_path,         GENERIC_READ | GENERIC_WRITE,         0,         0,         OPEN_EXISTING,         FILE_FLAG_OPEN_REPARSE_POINT | FILE_FLAG_BACKUP_SEMANTICS,         0      )
      if handle == INVALID_HANDLE_VALUE         raise StandardError, 'CreateFile() failed: ' + get_last_error      end      buf_target  = multi_to_wide("\\??\\")      length      = buf_target.size-2      buf_target  = buf_target[0,length] + from_path      length      = buf_target.size-2      wide_string = buf_target
      # REPARSE_JDATA_BUFFER      rdb = [         "0xA0000003L".hex,      # ReparseTag (IO_REPARSE_TAG_MOUNT_POINT)         length + 12,  # ReparseDataLength         0,                      # Reserved         0,                      # SubstituteNameOffset         length,       # SubstituteNameLength         length + 2,   # PrintNameOffset         0,                      # PrintNameLength         wide_string             # PathBuffer      ].pack('LSSSSSSa' + (length + 4).to_s)
      bytes = [length].pack('L')

      bool = DeviceIoControl(         handle,         CTL_CODE(FILE_DEVICE_FILE_SYSTEM, 41, METHOD_BUFFERED,FILE_ANY_ACCESS),         rdb,         rdb.size,         0,         0,         bytes,         0      )
      unless bool         error = 'DeviceIoControl() failed: ' + get_last_error
         RemoveDirectoryW.call(to_path)         CloseHandle(handle)         raise error      end
      CloseHandle(handle)
      self   end
Make test.rb like this:
from = "C:\\test"to = "?????"Dir.mkdir(from) unless File.exists?(from)Dir.create_junction(to, from)
The file format must be UTF8 DOS format.

Run with KCODE option like this:
ruby -Ku test.rb

Thanks Heesob, but I'm getting some weird segfaults with wide character 
functions and buffers over 245 characters.  I posted about this to 
ruby-talk as well.  Here's some sample code that demonstrates the problem:

require 'Win32API'

GetFullPathNameW = Win32API.new('kernel32', 'GetFullPathNameW', 'PLPP', 'L')

path = "C:\\test"
buf  = 0.chr * 260 # 245 or less works ok

if GetFullPathNameW.call(path, buf.size, buf, 0) == 0
    puts "Failed"
    exit
end

p buf.split("\0\0").first # BOOM!

I'm not sure what the significance of 245 or less is.  I can inspect 
'buf', copy and paste it to a separate editor as a string and run ops on 
it with no problem, so I'm very curious as to what's making Ruby segfault.

Anyway, I think I'm not going to worry about Unicode support for the 
initial release of the pure Ruby version for now.

Thanks,

Dan

I'm very curious too.

Your sample code don't segfault.
But I came across segfaults several times in modifing create_junction method.
It's behaviour is very unstable, as I insert p method,it sometimes runs OK.
It's location was mainly split method or get_last_error method.

I guess it's not related with 245 or 260, but it seems to underlying C
pointer memory access failure problem.
Can you give me a sample stable segfault generating code?

Park Heesob

To add even more mystery to this problem, that code isn't segfaulting 
for me at the moment, though it was regularly last night (I still have 
the console window open that shows the segfaults to prove it to myself).

I saw the same behavior you mentioned - inserting a 'puts' would 
sometimes cause code that was previously segfaulting to suddenly work.

Well, let's put the Unicode stuff on hold for now.  Perhaps deep 
inspection of string.c some day will reveal what the potential problem is.

Many thanks,

Dan

I have found out what is the problem.
It's not bug of Ruby or Windows, it is only bug of code.

First try this:

require 'Win32API'
GetFullPathNameW = Win32API.new('kernel32','GetFullPathNameW','PLPP', 'L')
for i in 1..100
path = "c:\\test"
buf  = 0.chr * 260
if GetFullPathNameW.call(path, buf.size, buf, 0) == 0
    puts "Failed"
end
p buf.split("\0\0").first
end

It will cause various errors like
uninitialized constant GetFullPathNameW (NameError)
or
segfault.

Next, try this:

require 'Win32API'
GetFullPathNameW = Win32API.new('kernel32','GetFullPathNameW','PLPP', 'L')
for i in 1..100
path = "c:\\test"
buf  = 0.chr * 260
# buf.size/2 -> actual length of buf
if GetFullPathNameW.call(path, buf.size/2, buf, 0) == 0
    puts "Failed"
end
p buf.split("\0\0").first
end

It runs Ok. but the result is not correct.

Next , try this:

require 'Win32API'
GetFullPathNameW = Win32API.new('kernel32','GetFullPathNameW','PLPP', 'L')
for i in 1..100
# append \0 to path
path = "c:\\test\0"
buf  = 0.chr * 260
# buf.size/2 -> actual length of buf in unicode string
if GetFullPathNameW.call(path, buf.size/2, buf, 0) == 0
    puts "Failed"
end
p buf.split("\0\0").first
end

It runs ok. The result is correct.

Finally, the complete and correct code is like this:

require 'Win32API'
GetFullPathNameW = Win32API.new('kernel32','GetFullPathNameW','PLPP', 'L')
for i in 1..100
path = "c\0:\0\\\0t\0e\0s\0t\0\0"
buf  = 0.chr * 260
# buf.size/2 -> actual length of buf in unicode string
if GetFullPathNameW.call(path, buf.size/2, buf, 0) == 0
    puts "Failed"
end
buf = buf.split("\0\0").first
buf = (buf.size % 2).zero? ? buf : buf+"\0"
p buf
end

Remeber, Ruby's string is terminated with "\0" implicitly, but UTF16
string requires double "\0".
For ascii chars, it happens trailing three "\0"  : one for ascii char
and two for string termination.

NotifyChangeEventLog() only checks every five seconds, max, iirc.  If an 
app logs more than one entry in that five second period it's going to be 
missed I'm afraid.

Hm....I suppose I could adapt change_notify to use the same approach 
that I used for tail.  I'll think about it.

Thoughts anyone?

While I understand why this code works, I'm still not entirely clear why 
the previous code would cause the interpreter to segfault.  Bad pointer 
address?

In any case, excellent work, thank you!

Now I'm trying to work out a general approach for the windows-pr stuff. 
   Given a method like this:

def GetFullPathName(file, buf, buf_size, part)
    if $KCODE != 'NONE'
       GetFullPathNameW.call(file, buf, buf_size, part)
    else
       GetFullPathName.call(file, buf, buf_size, part)
    end
end

Should I modify it to try to do a best-guess?

if $KCODE != 'NONE'
    GetFullPathNameW.call(file, buf, buf_size/2, part)
end

Or do you think that's the user's job?

Thanks,

Dan

Yes, Ruby's string is not just character array, it is actually a
structure and a tainted structure causes unexpected behaviour.

Be careful, before calling GetFullPathNameW, the "file" must be UTF16 string.
I recommend all function call using W function, and if string is not
UTF16 then first convert it to UTF16 string.
$KCODE must be used to only determine the string is UTF8 string, not
determine to call wheter Ansi function or W function.
Because Ruby interpreter cannot handle UTF16 code file, the user has
no chance to use UTF16 string in real world in the ruby code.

Sample code is like this:

     from = multi_to_wide(from)
     to = multi_to_wide(to)
     if GetFullPathNameW.call(from, from_path.size, from_path, 0) == 0
        raise StandardError, 'GetFullPathName() failed: ' + get_last_error
     end
     if GetFullPathNameW.call(to, to_path.size, to_path, 0) == 0
        raise StandardError, 'GetFullPathName() failed: ' + get_last_error
     end

I think the user would'nt care about file name is unicode or ansi string.

What would you recommend then?  How should I determine within Ruby if 
the string being passed to a function is UTF16?  IsTextUnicode()? 
Something else?

How would you define GetFullPathName within file.rb (from windows-pr) 
then, for example?

Thanks,

Dan

The user might not call function with UTF16 by accident.
But the user who want call function with UTF16 string on purpose, use
utf16 flag.

How about this?

def GetFullPathName(file, buf_size, buf, part, utf16 = false)
   file = multi_to_wide(file) unless utf16
   GetFullPathNameW.call(file, buf.size/2, buf, part)
end

Except that means adding an extra argument to a lot of methods.

Hm....what about:

def GetFullPathName(file, buf_size, buf, part)
    file = multi_to_wide(file) unless IsTextUnicode(file)
    GetFullPathNameW.call(file, buf.size/2, buf, part)
end

A little more work for me, but less for the user to remember.

Will that work? Or do you think IsTextUnicode() is too unreliable?

(Sorry if you answered this previously)

Dan

That's Ok for internal Use.
But what if the user wants the result of the function ?
Every function needs to be a->w;callw;w->a; conversion like this?

 def GetFullPathName(file, buf_size, buf, part)
    file = multi_to_wide(file) unless IsTextUnicode(file)
    GetFullPathNameW.call(file, buf.size/2, buf, part)
    buf = wide_to_multi(buf)
 end

I recommend to separate two functions like this:

 def GetFullPathName(file, buf_size, buf, part)
    GetFullPathName.call(file, buf.size/2, buf, part)
 end

 def GetFullPathNameW(file, buf_size, buf, part)
    file = multi_to_wide(file) unless IsTextUnicode(file)
    GetFullPathNameW.call(file, buf.size/2, buf, part)
 end

I think it is a useful function.
I just don't want to make slow code with using another api function:)

To me it seems that it is always true as E_S_R == 2.
Maybe this is how it was meant:

I haven't understood the rest of the code, so I'm not sure about the solution.

Message:
Not only is the code wrong, some testing revealed that code was the source of another bug.  Specifically, a seek + backwards read would loop infinitely.

I believe this is the proper code:

if flags & EVENTLOG_SEEK_READ > 0
   if flags & EVENTLOG_FORWARDS_READ > 0
      offset = buf[8,4].unpack('L').first + 1
   else
      offset = buf[8,4].unpack('L').first - 1
   end
end

I'll add some more tests for this.  Many thanks for the report!

Initial Comment:
This is another version Samuel Tesla's patch which sets $? and also returns the Process::Status when popen3/4 is called with a block (i.e. this patch merges changes from the two patches Samuel submitted).

Note that this implementation is not thread-safe. As the attachment will demonstrate.

I've added another patch for the popen3 library which sets $? and adds
Process::Status a return when popen3/4 is called with a block thus
making it closer to the Open4. This is a merge of a couple of patches

Note that this implementation is not thread-safe (as is demonstrated
by sample code I've provided.) I'd be very interested in seeing a
tweak that would make this thread-safe if anyone has ideas about how
to do that.

I'd also be grateful for a release which includes this patch (or
something better) and that would be compatible with the latest
one-click installer.

Thanks to all for contributing and maintaining this valuable library.

Wow, I never imagined folks running a series of eventlogs in different 
threads.

Anyone have any ideas on this?

I guess the code needs something like this for thread-safe:

   require 'thread'
   semaphore = Mutex.new

   semaphore.synchronize {
       get_last_error
    }

Since the 1.8.4 One-click installer is based on VC++ 6.0 which is no
longer available, I am looking for alternative ways of building
win32-utils so as avoid segfaults. Has anyone used MingGW
successfully? When I run ruby extconf.rb from MSYS the resulting make

first?

If Ruby is mswin32 (VC), you need VC to build extensions.

Building all with mingw32 will brake existing mswin32 binaries gem you
use, so be careful with that.

I have VC Toolkit 2003 bundled with platform SDK headers and libs. (14Mb 7zip).

I used it to build win32 gems for mongrel (and present no binary
compatibility issues with msvcrt).

Mail me off the list to send you a link for download. I could not
share it due non-distributing lincense of Platform SDK, but
peer-to-peer way of sharing is allowed.

(cc'd to the devel list)

I just noticed the "China Standard Time".  Do your event log records 
contain non-ascii text?  If so, I'll have to switch to the wide 
character version of ReadEventLog() I think.  This might also explain 
the duplicate records you showed me earlier (?).

Where are you located, btw?  I forgot.

Also, regarding the EventLog#notify_change method, I just remembered 
something.  From the MSDN docs: The NotifyChangeEventLog function does 
not work with remote handles.

If there's a way to remotely log to a *nix syslog from Windows, I'm 
afraid I don't know what it is.  Anyone?

The win32-service package should work.  Check it out.

I guess the event logging Windows machine code page is different from

I think the Snare Agent for
Windows(http://www.intersectalliance.com/projects/SnareWindows/index.html)
might be useful.

If your OS is XP or 2003, you can use the remote desktop connection

Hi all,

I'm starting to set things up to move win32-open3 towards a pure Ruby
solution.  I've got a windows-pipe module setup, but now I need to
define some of the msvcrt IO functions.  However, I can't find
documentation on MSDN or my system for the following:

FMODE_READABLE
FMODE_WRITABLE
FMODE_BINMODE

MakeOpenFile()
io_alloc()

A recursive search on my header files didn't reveal anything.  Any
ideas?

Thanks,

Dan

Along the same lines as the last question - how can I get to functions
like MakeOpenFile via Win32API?  It doesn't seem to be exported by
msvcrt-ruby18.

Possible?  Or am I out of luck?

Hi Dan,

How's it going?

Regarding MakeOpenFile... looking in
C:\ruby\lib\ruby\1.8\i386-mswin32\rubyio.h, its defined as a macro:

#define MakeOpenFile(obj, fp) do {\
    if (RFILE(obj)->fptr) {\
	rb_io_close(obj);\
	free(RFILE(obj)->fptr);\
	RFILE(obj)->fptr = 0;\
    }\
    fp = 0;\
    fp = RFILE(obj)->fptr = ALLOC(OpenFile);\
    fp->f = fp->f2 = NULL;\
    fp->mode = 0;\
    fp->pid = 0;\
    fp->lineno = 0;\
    fp->path = NULL;\
    fp->finalize = 0;\
} while (0)

so the only way to access it would be to #include "rubyio.h", which
doesn't help much for your pure Ruby solution.
