[solved]pacman seems to be stuck in infinite loop

Hi, All
I was trying out gnome2.20 which is till in testing.
Installation of the packages was smooth, but I could not start X after the installation.
The Xorg logs said that there was no X sever installed while the It was listed in the pacman -Q
I decided to remove everything and do it again so I did a
pacman -Rc xorg-server
During the removal I thought of taking a backup of my xorg.conf and intruppted the package removal process by Ctrl+C.
After copying the xorg.conf
I re ran
pacman -Rc xorg-server
but it seems to be running in loop.
The message printed are like(these are not the actual message as I dun have an acces to the system)
Kmplayer not found in database
Kmplayer not found in database
Kmplayer not found in database
So presently am not able to do anything (install/remove X). Text mode is working fine though.
Can somebdy suggest some workaround(deleting/adding) something from/in the pacman database. or smthing like that.
Thanks
Sri

I would rather try to do that with kmplayer (pacman -S or pacman -R or both).
Otherwise, the loop itself should be fixed in pacman 3.1.
But what caused the loop in the first place, I am not sure. There might still be a problem in the interruption handling.
Pacman is supposed to catch ctrl+c for exiting cleanly, But maybe it failed to in this case.. I don't know.

Hi altofts,
Thanks for using Apple Support Communities. You can try resetting and restoring your iPod nano to see if that helps with the restart loop:

[solved] Pacman seems to think i have nothing installed

ok im quite new to arch linux and ive been attempting to get to grips with it quickly so i may have done something stupid here...
i installed arch with kde and have switched recently to the ice kernel, due to tryingto get compiz running and needing to update my graphics driver....
having done this however pacman seems to have lost the fact that it has ever installed anything...
is there a way to remedy this...
64bit btw...
thanks in advance for any input and let me know if i need to give any extra info...

Well, pacman stores everything it knows about your system's packages in /var/lib/pacman/local -- if that dir is empty, then you're in trouble. There's a script floating around somewhere that takes your pacman.log from /var/log and tries to re-install every package that should be on your system in an attempt to recreate /var/lib/pacman/local - I can never remember where that script is though; you'll have to do a search.

SQL stored procedure Staging.GroomDwStagingData stuck in infinite loop, consuming excessive CPU

Hello
I'm hoping that someone here might be able to help or point me in the right direction. Apologies for the long post.
Just to set the scene, I am a SQL Server DBA and have very limited experience with System Centre so please go easy on me.
At the company I am currently working they are complaining about very poor performance when running reports (any).
Quick look at the database server and CPU utilisation being a constant 90-95%, meant that you dont have to be Sherlock Holmes to realise there is a problem. The instance consuming the majority of the CPU is the instance hosting the datawarehouse and in particular
a stored procedure in the DWStagingAndConfig database called Staging.GroomDwStagingData.
This stored procedure executes continually for 2 hours performing 500,000,000 reads per execution before "timing out". It is then executed again for another 2 hours etc etc.
After a bit of diagnosis it seems that the issue is either a bug or that there is something wrong with our data in that a stored procedure is stuck in an infinite loop
System Center 2012 SP1 CU2 (5.0.7804.1300)
Diagnosis details
SQL connection details
program name = SC DAL--GroomingWriteModule
set quoted_identifier on
set arithabort off
set numeric_roundabort off
set ansi_warnings on
set ansi_padding on
set ansi_nulls on
set concat_null_yields_null on
set cursor_close_on_commit off
set implicit_transactions off
set language us_english
set dateformat mdy
set datefirst 7
set transaction isolation level read committed
Store procedures executed
1. dbo.p_GetDwStagingGroomingConfig (executes immediately)
2. Staging.GroomDwStagingData (this is the procedure that executes in 2 hours before being cancelled)
The 1st stored procedure seems to return a table with the "xml" / required parameters to execute Staging.GroomDwStagingData
Sample xml below (cut right down)
<Config>
<Target>
<ModuleName>TransformActivityDim</ModuleName>
<WarehouseEntityName>ActivityDim</WarehouseEntityName>
<RequiredWarehouseEntityName>MTV_System$WorkItem$Activity</RequiredWarehouseEntityName>
<Watermark>2015-01-30T08:59:14.397</Watermark>
</Target>
<Target>
<ModuleName>TransformActivityDim</ModuleName>
<WarehouseEntityName>ActivityDim</WarehouseEntityName>
<RequiredWarehouseEntityName>MTV_System$WorkItem$Activity</RequiredWarehouseEntityName>
<ManagedTypeViewName>MTV_Microsoft$SystemCenter$Orchestrator$RunbookAutomationActivity</ManagedTypeViewName>
<Watermark>2015-01-30T08:59:14.397</Watermark>
</Target>
</Config>
If you look carefully you will see that the 1st <target> is missing the ManagedTypeViewName, which when "shredded" by the Staging.GroomDwStagingData returns the following result set
Example
DECLARE @Config xml
DECLARE @GroomingCriteria NVARCHAR(MAX)
SET @GroomingCriteria = '<Config><Target><ModuleName>TransformActivityDim</ModuleName><WarehouseEntityName>ActivityDim</WarehouseEntityName><RequiredWarehouseEntityName>MTV_System$WorkItem$Activity</RequiredWarehouseEntityName><Watermark>2015-01-30T08:59:14.397</Watermark></Target><Target><ModuleName>TransformActivityDim</ModuleName><WarehouseEntityName>ActivityDim</WarehouseEntityName><RequiredWarehouseEntityName>MTV_System$WorkItem$Activity</RequiredWarehouseEntityName><ManagedTypeViewName>MTV_Microsoft$SystemCenter$Orchestrator$RunbookAutomationActivity</ManagedTypeViewName><Watermark>2015-01-30T08:59:14.397</Watermark></Target></Config>'
SET @Config = CONVERT(xml, @GroomingCriteria)
SELECT
ModuleName = p.value(N'child::ModuleName[1]', N'nvarchar(255)')
,WarehouseEntityName = p.value(N'child::WarehouseEntityName[1]', N'nvarchar(255)')
,RequiredWarehouseEntityName =p.value(N'child::RequiredWarehouseEntityName[1]', N'nvarchar(255)')
,ManagedTypeViewName = p.value(N'child::ManagedTypeViewName[1]', N'nvarchar(255)')
,Watermark = p.value(N'child::Watermark[1]', N'datetime')
FROM @Config.nodes(N'/Config/*') Elem(p)
/* RESULTS - NOTE THE NULL VALUE FOR ManagedTypeViewName
ModuleName WarehouseEntityName RequiredWarehouseEntityName ManagedTypeViewName Watermark
TransformActivityDim ActivityDim MTV_System$WorkItem$Activity NULL 2015-01-30 08:59:14.397
TransformActivityDim ActivityDim MTV_System$WorkItem$Activity MTV_Microsoft$SystemCenter$Orchestrator$RunbookAutomationActivity 2015-01-30 08:59:14.397
When the procedure enters the loop to build its dynamic SQL to delete relevant rows from the inbound schema tables it concatenates various options / variables into an executable string. However when adding a NULL value to a string the entire string becomes
NULL which then gets executed.
Whilst executing "EXEC(NULL)" would cause SQL to throw an error and be caught, executing the following doesnt
DECLARE @null_string VARCHAR(100)
SET @null_string = 'hello world ' + NULL
EXEC(@null_string)
SELECT @null_string
So as it hasnt caused an error the next part of the procedure is to move to the next record and this is why its caught in an infinite loop
DELETE @items WHERE ManagedTypeViewName = @View
The value for the variable @View is the ManagedTypeViewName which is NULL, as ANSI_NULLS are set to ON in the connection and not overridded in the procedure then the above statement wont delete anything as it needs to handle NULL values differently (IS NULL),
so we are now stuck in an infinite loop executing NULL for 2 hours until cancelled.
I amended the stored procedure and added the following line before the loop statement which had the desired effect and "fixed" the performance issue for the time being
DELETE @items WHERE ManagedTypeViewName IS NULL
I also noticed that the following line in dbo.p_GetDwStagingGroomingConfig is commented out (no idea why as no notes in the procedure)
--AND COALESCE(i.ManagedTypeViewName, j.RelationshipTypeViewName) IS NOT NULL
There are obviously other ways to mitigate the dynamic SQL string being NULL, there's more than one way to skin a cat and thats not why I am asking this question, but what I am concerned about is that is there a reason that the xml / @GroomingCriteria is incomplete
and / or that the procedures dont handle potential NULL values.
I cant find any documentation, KBs, forum posts of anyone else having this issue which somewhat surprises me.
Would be grateful of any help / advice that anyone can provide or if someone can look at their 2 stored procedures on a later version to see if it has already been fixed. Or is it simply that we have orphaned data, this is the bit that concerns most as I dont
really want to be deleting / updating data when I have no idea what the knock on effect might be
Many many thanks
Andy

First thing I would do is upgrade to 2012 R2 UR5. If you are running non-US dates you need the UR5 hotfix also.

(it seems anyway). It doesnt even make it into the while statement. If i replace the while with an if statement, everything works smoothly. Does anyone know what is actually happening here and why?
Thanks for your time.

Why didnt the java compiler report the ;? or the
missing =?Because they're both syntactically valid.
You might want to code a loop with no body:
while ((ch = readChar()) != 0);
(same as)
while ((ch = readChar()) != 0)
// do nothing
And you might want to assign a boolean variable and compare it at the same time:
while (flag = callSomeMethod())
(as opposed to)
while ((flag = callSomeMethod()) == true)
Although in both cases I'd write them differently rather than making a statement which has 'side-effects' and makes for slightly less-readable code.

Apple TV 1st gen stuck in infinite loop

Hi
This has probably been covered a few times but the only answers I could find was from an archived discussion.
The other day I was given an Apple TV 1st gen, it had not been used for quite some time, and decided to upgrade the software, when I noticed it still had old pictures and music on from the previous user, not wanting to keep these pictures, I decided to reset the machine to factory settings, which it did, but on the restart it was stuck at a loop giving me a code to enter into iTunes, and then resetting and giving me a different code.
i've tried several resets of the settings, holding menu and - together, but still having no joy.
Its never been tampered with, but its really annoying me.
Can anyone help? this is a very old product so figure something might have been done during this time
Cheers
Dave

sounddave,
I have been in the middle of the same problem for months.
I think the problem is with the software version that the older 40GB Apple TV's revert to after the factory restore. Mine reverted to version 1.0, and that is when the loop started happening. Since when did a factory restore become a factory paper weight creator!
I read somewhere that the Apple TV looks at an Apple server and the older software doesn't play well with the updated server causing it to keep rebooting. I'll try to find a link about this if I can find it again. I remember reading that it happened to a bunch of people with older Apple TV software on a particular day that Apple upgraded their server.
If you don't let your Apple TV connect to the internet, it will stop the infinite loop, but it also means you can't upgrade your software. I haven't tried it yet, but it also might be an issue with newer versions of iTunes.
I tested this by unplugging my router, and the Apple TV stopped looping.
I tried to fix this before without success, but I am really determined this time.

PowerShell 3.0 stuck in infinite loop resolving members internally (is this a PS bug??)

Sorry for long post... I have this scenario:
- Issue is on PS3, PS2 works fine
- I create a new object via "$myObj = New-Object PSObject"
- I append a number of PSMembers to it via something similar to:
"if (-not (Get-Member -InputObject $myObj -Name MyProperty))
Add-Member -InputObject $myObj -MemberType ScriptProperty -Name MyProperty -Value { return MyFunction }
I am seeing situations where what I believe is the call to "Get-Member" causes a huge number of invocations that appear to be calling the equivalent of the "MyFunction" in the above sample. I have debug statements in the MyFunction
function and nested functions and can see they are called by what appears to be the PS framework itself. Even running a "Get-PSCallstack" call from one of these functions seems to also trigger the debug statements to be hit (midway through the callstack
output??!) - bit confused by that but it's like PS is invoking the member in order to reflect it or something.
I used Trace-Command and could see that the "MemberResolution" trace source is repeatedly/infinitely called with the output:
MemberResolution Information: 0 :         Matching "*"
MemberResolution Information: 0 :             Generating the total list of members
MemberResolution Information: 0 :                 Type table members: 0.
MemberResolution Information: 0 :                 Adapted members: 0.
MemberResolution Information: 0 :             21 total matches.
This appears to be in an infinite loop. Therefore I added "-ListenerOption Callstack" to the Trace-Command call and captured the following and more (notice the call to PSObject.ToStringEmptyBaseObject()):
at System.Management.Automation.PSObject.AdapterGetMembersDelegate[T](PSObject msjObj)
   at System.Management.Automation.PSMemberInfoIntegratingCollection`1.GetIntegratedMembers(MshMemberMatchOptions matchOptions)
   at System.Management.Automation.PSMemberInfoIntegratingCollection`1.Match(String name, PSMemberTypes memberTypes, MshMemberMatchOptions matchOptions)
   at System.Management.Automation.PSObject.ToStringEmptyBaseObject(ExecutionContext context, PSObject mshObj, String separator, String format, IFormatProvider formatProvider)
   at System.Management.Automation.PSObject.ToString(ExecutionContext context, Object obj, String separator, String format, IFormatProvider formatProvider, Boolean recurse, Boolean unravelEnumeratorOnRecurse)
   at System.Management.Automation.PSObject.ToString()
   at System.String.Join(String separator, Object[] values)
   at System.Management.Automation.ParameterBinderBase.BindParameter(CommandParameterInternal parameter, CompiledCommandParameter parameterMetadata, ParameterBindingFlags flags)
I then disassembled the relevant code in Reflector and could see that the ToString() method of PSObject has a check for "if obj.immediateBaseObjectIsEmpty" then to call the ToStringEmptyBaseObject() function. I could also see that the immediateBaseObjectIsEmpty
field is set in the CommonInitialization internal method if "obj is PSCustomObject" (which is the actual object type you get when you New-Object PSObject).
I then updated my code to create "$myObj = New-Object Object" (i.e. System.Object instead) and the issue goes away.
Can anyone explain what I may have done wrong here or is this looking like a bug in PowerShell?
Cheers!

Hi Matt,
I'm not sure if we are on the same page? Getting the list of (i.e. metadata of) the members shouldn't invoke the member. I have used this technique in many places and it's never been an issue whereby you "wrap" a utility function with
a ScriptProperty or ScriptMethod to provide OO semantics on a PS object. The member isn't invoked by Get-Member, only when it's called explicitly.
Here's a small example:
function TestFunction
Write-Host "TestFunction called"
return "TestFunction return value"
$myObj = New-Object PSObject
Add-Member -InputObject $myObj -MemberType ScriptProperty -Name TestScriptProperty -Value `
Write-Host "TestScriptProperty called"
return TestFunction
Write-Host "Getting members"
Get-Member -InputObject $myObj -Name TestScriptProperty | Select *
Write-Host "Invoking property"
$myObj.TestScriptProperty
Here's the output (Get-Member output a bit mangled due to the text wrapping):
Getting members
TypeName                                   Name
MemberType Definition
System.Management.Automation.PSCustomOb... TestScriptProperty
ScriptProperty System.Object TestScriptProperty {get=...
Invoking property
TestScriptProperty called
TestFunction called
TestFunction return value
Yup I see your point, but when you run your original code with this example object you can see there is no loop. There must either be a loop in the function or in the body of the script itself. This is very tough to troubleshoot without seeing the code you
are actually running.
You said you are adding several members to the custom object. Is this done in a loop?

Empty trash stuck in infinite loop....

I just upgraded to Mtn Lion and I have a hard drive with time machine back up from a leopard machine, I wanted to delete that, and use the drive with Mtn lion, I put the backups folder into trash and tried to empty it, it is stuck in an infinite loop, the items to delete is in -ve......anybody else seen this? how to recover, if I stop the process, the files are still there...any solutions?

Stop the process. Remove the files from Trash and put them back on the disk they came from.
Next, open Disk Utility (Applications/Utilities/Disk Utility.app), choose the hard disk that you were trying to delete the files from. Click the 'Erase' tab and then 'Erase...'.

Iphone stuck in infinite loop, HELP!

my iphone after resetting all settings through settings>general>reset, is stuck in an infinite loop.
it turns on, shows the apple logo, then about a minute later the loading symbol appears, after 10mins it quickly flashs black and then starts the loop again, i have left it for over 12 hours, to see if it will fix itself, but it wont.
i cant get it into dfu or recovery mode, it wont even turn off until it runs out of battery and then repeats its loop. when i charge it it just starts the loop again!
please i really need help, if i cant resolve this problem, im not going to buy the ipad and the iphone 4g as i planned to do so.
please could anyone help!

If you can't get your iPhone into DFU or recovery mode, there is a major problem. You can make an appointment at an Apple store if there is one nearby.
This is a user to user help forum only, so doubtful if any fellow users will lose any sleep over your threat not to purchase an iPad or the next generation iPhone when released if this problem cannot be resolved. If not, more than likely there is a hardware problem or failure. If a problem arises with your PC that you cannot resolve, are you not going to purchase another PC either?

How to install firefox, when trying says previous version detected must reboot. Stuck in infinite loop

Trying to install newly downloaded firefox (had previously removed about a month ago through programs uninstall), however when I try to run the install, it says a previous version is detected, and the system must reboot. System reboots, but install never happens, I go to run the download again, and it appears I'm stuck in an infinite loop. I can't get latest version firefox to install

I succeeded in installing Firefox after getting this message.
I went to add/remove programs to verify that Firefox wasn't on the list, then I went to the program files directory and deleted the Mozilla/Firefox directory that was left over from the uninstall.
I attempted to reinstall Firefox and, voila, it installed with no issues.
I know it can be dangerous to delete a program directory, but if you have properly uninstalled the program itself and it isn't in the add/remove list (but still exists in the program directory), deleting the parent directory for the program should affect system performance.
I have done this dozens of times over the years and never had a problem (I have NEVER deleted a system directory though. That would be a BAD idea).
I hope this helps.

Java Pattern Matcher (Pattern.class bug? Stuck in Infinite Loop)

Hi,
I'm using the java pattern matcher and it appears to be stuck in an infinite loop and will not return from Pattern.class.
It stays stuck in the following two code sequences...
I'm using the following regex...
java.util.regex.Matcher[pattern=[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|biz|info) region=0,353648 lastmatch=
MAIN BLOCK STUCK IN LOOP:
boolean study(TreeInfo info) {
if (type != INDEPENDENT) {
int minL = info.minLength;
atom.study(info);
info.minLength = minL;
info.deterministic = false;
return next.study(info);
} else {
atom.study(info);
return next.study(info);
SECOND BLOCK STUCK IN LOOP:
boolean match(Matcher matcher, int i, CharSequence seq) {
// Check for zero length group
if (i > matcher.locals[beginIndex]) {
int count = matcher.locals[countIndex];
if (count < cmin) {
matcher.locals[countIndex] = count + 1;
boolean result = body.match(matcher, i, seq);
// If match failed we must backtrack, so
// the loop count should NOT be incremented
if (!result)
matcher.locals[countIndex] = count;
return result;
if (next.match(matcher, i, seq))
return true;
if (count < cmax) {
matcher.locals[countIndex] = count + 1;
boolean result = body.match(matcher, i, seq);
// If match failed we must backtrack, so
// the loop count should NOT be incremented
if (!result)
matcher.locals[countIndex] = count;
return result;
return false;
return next.match(matcher, i, seq);
Is this a bug with the Java 1.6 Pattern Matcher?
Thanks

It works on most of the other STRINGS but when I do a REGEX on the the html source for http://www.exponent.com it will get stuck...
Pattern p = Pattern.compile("[a-zA-Z0-9+_~-]+(?:\\.[a-zA-Z0-9+_~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?\\.)+(?:com|org|net|biz|info|[a-zA-Z]{2})");Thanks,

I seem to be stuck in a loop re-installing the google toolbar for firefox, since i endup at the "agree and install" page every time i reestart firefox

On my netbook, I have used the Google Toolbar for Firefox, with its handy Bookmarks access, for several years, but it appears to have become "invisible" when I open Firefox. I tried reinstalling it, and Firefox seems to perform the download, but when I restart Firefox to complete the download, itr opens on the "Start the Download" page, and the toolbar is still nowhere in sight. What am I doing wrong?

I agree with whereitis above, I hate it when options are removed (ex: the Bookmarks side panel (Ctrl-B) button missing) etc.. Firefox's major BOLD one-liner is: CUSTIMAZATION. Now to regain this CUSTIMAZATION freedom, Firefox suggest to solve this by installing the ADDON "Classic Theme Restorer". I don't want to install any ADDON to customize Firefox! I went with Firefox because it was CUSTOMIZABLE, and that is the only reason why I went with this web browser! Now, Firefox is asking me to add an ADDON to CUSTOMIZE it. What is this?!
