  • Exiting a reboot loop

    - by user12617035
    If you're in a situation where the system is panic'ing during boot, you can use # boot net -s to regain control of your system. In my case, I'd added some diagnostic code to a (PCI) driver (that is used to boot the root filesystem). There was a bug in the driver, and each time during boot, the bug occurred, and so caused the system to panic: ... 000000000180b950 genunix:vfs_mountroot+60 (800, 200, 0, 185d400, 1883000, 18aec00) %l0-3: 0000000000001770 0000000000000640 0000000001814000 00000000000008fc %l4-7: 0000000001833c00 00000000018b1000 0000000000000600 0000000000000200 000000000180ba10 genunix:main+98 (18141a0, 1013800, 18362c0, 18ab800, 180e000, 1814000) %l0-3: 0000000070002000 0000000000000001 000000000180c000 000000000180e000 %l4-7: 0000000000000001 0000000001074800 0000000000000060 0000000000000000 skipping system dump - no dump device configured rebooting... If you're logged in via the console, you can send a BREAK sequence in order to gain control of the firmware's (OBP's) prompt. Enter Ctrl-Shift-[ in order to get the TELNET prompt. Once telnet has control, enter this: telnet> send brk You'll be presented with OBP's prompt: ok You then enter the following in order to boot into single-user mode via the network: ok boot net -s Note that booting from the network under Solaris will implicitly cause the system to be INSTALLED with whatever software had last been configured to be installed. However, we are using boot net -s as a "handle" with which to get at the Solaris prompt. Once at that prompt, we can perform actions as root that will let us back out our buggy driver (ok...

This is something that you should also have recorded before you ever loaded your.. er...

  • Why not write all tests at once when doing TDD?

    - by RichK
    The Red - Green - Refactor cycle for TDD is well established and accepted. We write one failing unit test and make it pass as simply as possible. What are the benefits to this approach over writing many failing unit tests for a class and make them all pass in one go. The test suite still protects you against writing incorrect code or making mistakes in the refactoring stage, so what's the harm? Sometimes it's easier to write all the tests first as a form of 'brain dump' to quickly write down all the expected behavior in one go.

  • MySQL tables corrupted and need to be repaired,how to fix them and how to prevent this [on hold]

    - by Hbirjand
    We have developed a software that uses,MySQL database,and after some month of usage,some of the database tables had been corrupted and need to be repaired,what is the cause of this corruption? How can we fix them? How can we prevent the database tables from corruption. Because of the corruption,we are not able to create a backup using Navicat,and we can not generate a dump too. Is that possible to fix this tables using MySQL engine,and some of this corruption is about empty fields in database tables.

  • mysqld crashes on any statement

    - by ??iu
    I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement. The client looks like: Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor.

  • IPCop Packet Mangling

    - by Zenham
    I've found myself in a pickle replacing an old firewall for a client this afternoon. I'm configuring their new IPCop firewall (1.4.21), Zerina OpenVPN addon is installed. What I need to do: There are three network interfaces, currently set up as red (WAN), green (LAN, 192.168.20.0/24) and orange (remote network 10.1.20.0/24). The orange interface is a direct fiber link to another organization. Simple description: Traffic and networks appear to be properly configured at this point, but I have many (150+) specific IPs on the LAN which, when accessing the resources on the 10.1.20.x network, need to be mangled to appear to be coming from the 10.1.20.0/24 network (and return traffic properly delivered). The routing on the far side was configured earlier and should be fine, but I need to redirect any packets coming across destined for those IPs to end up at their proper destination. The addressing is fixed and predictable (ie. 192.168.20.125 - 10.1.20.125). I need to insert whatever rules I have into the IPCop ruleset through /etc/rc.local I know, I'm just not sure about how I should structure this. There's CUSTOMOUTPUT and CUSTOMINPUT targets, both which currently just consist of the single rule redirecting packets to the OVPNOUTPUT/OVPNINPUT targets, so I'm guessing I should insert a rule matching outbound packets destined for the 10.1.20.x network and redirecting to a new target (maybe called TO-ORANGE) and a rule at the top of CUSTOMINPUT which redirects to a FROM-ORANGE target. Under those targets, I would have rules which do the IP matching and mangling. Am I approaching this right? If so, I'm not very familiar with mangle, and would appreciate seeing examples of how to write that source-IP rewrite. If not, how would you suggest doing this? TIA! edit: I notice additionally that the nat table has CUSTOMPREROUTING and CUSTOMPOSTROUTING targets, I guess I could alternatively post the rules in there....

  • mysqld crashes on any statement

    - by ??iu
    I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement. The client looks like: Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor.

  • How to get desired FireFox last tab behavior?

    - by JustJeff
    All tabs should be the same; so if any of the have a 'close' button, they all should, including the last tab. I see no reason that a tab's close button should suddenly vanish simply b/c that tab has become the last one open. If I have N tabs open, and park the mouse over the left-most tab's close button, this vanishing close button trick means now I have to make a large mouse move to get to the app's close button. Unsat. Mouse moves = too many milliseconds wasted. Closing the last tab should NOT take me to my home page, or any other page whatsoever. I want the browser to close with the last tab. I do not expect or want "new tab" behavior when I click a Close button. Now, I've gone into about:config and played with browser.tabs.closeWindoWithLastTab, but this setting oversteps its purpose; while it does make the browser close, for some inexplicable reason, it also suppresses the last tab's close button! I have tried the "last tab close button" add-on, and while this does restore the close button, the add-on oversteps by taking the liberty of turning closeWindowWithLastTab off. Is there some way out of this pickle? Is it too hard to just code things to provide simple, orthogonal actions, so that everybody can config the UI to their liking, and not just to a few pre-fab configurations that the developers think everyone should like? Btw, FF 13.0.1 on ms windows

    This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)? This binary format is not discussed in the in the documentation here: http://developer.android.com/guide/topics/manifest/manifest-intro.html Note: I want to access this information from outside the Android environment, preferably from Java.

  • npoi export from datatable

    - by Iulian
    I have an asp.net website that will generate some excel files with 7-8 sheets of data. The best solution so far seems to be NPOI, this can create excel files without installing excel on the server, and has a nice API simillar to the excel interop. However i can't find a way to dump an entire datatable in excel similar to CopyFromRecordset Any tips on how to do that , or a better solution than NPOI ?

  • Large Object Heap Fragmentation

    - by Paul Ruane
    The C#/.NET application I am working on is suffering from a slow memory leak. I have used CDB with SOS to try to determine what is happening but the data does not seem to make any sense so I was hoping one of you may have experienced this before. The application is running on the 64 bit framework. It is continuously calculating and serialising data to a remote host and is hitting the Large Object Heap (LOH) a fair bit. However, most of the LOH objects I expect to be transient: once the calculation is complete and has been sent to the remote host, the memory should be freed. What I am seeing, however, is a large number of (live) object arrays interleaved with free blocks of memory, e.g., taking a random segment from the LOH: 0:000> !DumpHeap 000000005b5b1000 000000006351da10 Address MT Size ... 000000005d4f92e0 0000064280c7c970 16147872 000000005e45f880 00000000001661d0 1901752 Free 000000005e62fd38 00000642788d8ba8 1056 <-- 000000005e630158 00000000001661d0 5988848 Free 000000005ebe6348 00000642788d8ba8 1056 000000005ebe6768 00000000001661d0 6481336 Free 000000005f214d20 00000642788d8ba8 1056 000000005f215140 00000000001661d0 7346016 Free 000000005f9168a0 00000642788d8ba8 1056 000000005f916cc0 00000000001661d0 7611648 Free 00000000600591c0 00000642788d8ba8 1056 00000000600595e0 00000000001661d0 264808 Free ... Obviously I would expect this to be the case if my application were creating long-lived, large objects during each calculation. (It does do this and I accept there will be a degree of LOH fragmentation but that is not the problem here.) The problem is the very small (1056 byte) object arrays you can see in the above dump which I cannot see in code being created and which are remaining rooted somehow. Also note that CDB is not reporting the type when the heap segment is dumped: I am not sure if this is related or not. If I dump the marked (<--) object, CDB/SOS reports it fine: 0:015> !DumpObj 000000005e62fd38 Name: System.Object[] MethodTable: 00000642788d8ba8 EEClass: 00000642789d7660 Size: 1056(0x420) bytes Array: Rank 1, Number of elements 128, Type CLASS Element Type: System.Object Fields: None The elements of the object array are all strings and the strings are recognisable as from our application code. Also, I am unable to find their GC roots as the !GCRoot command hangs and never comes back (I have even tried leaving it overnight). So, I would very much appreciate it if anyone could shed any light as to why these small (<85k) object arrays are ending up on the LOH: what situations will .NET put a small object array in there? Also, does anyone happen to know of an alternative way of ascertaining the roots of these objects? Thanks in advance. Update 1 Another theory I came up with late yesterday is that these object arrays started out large but have been shrunk leaving the blocks of free memory that are evident in the memory dumps. What makes me suspicious is that the object arrays always appear to be 1056 bytes long (128 elements), 128 * 8 for the references and 32 bytes of overhead. The idea is that perhaps some unsafe code in a library or in the CLR is corrupting the number of elements field in the array header. Bit of a long shot I know... Update 2 Thanks to Brian Rasmussen (see accepted answer) the problem has been identified as fragmentation of the LOH caused by the string intern table! I wrote a quick test application to confirm this: static void Main() { const int ITERATIONS = 100000; for (int index = 0; index < ITERATIONS; ++index) { string str = "NonInterned" + index; Console.Out.WriteLine(str); } Console.Out.WriteLine("Continue."); Console.In.ReadLine(); for (int index = 0; index < ITERATIONS; ++index) { string str = string.Intern("Interned" + index); Console.Out.WriteLine(str); } Console.Out.WriteLine("Continue?"); Console.In.ReadLine(); } The application first creates and dereferences unique strings in a loop. This is just to prove that the memory does not leak in this scenario. Obviously it should not and it does not. In the second loop, unique strings are created and interned. This action roots them in the intern table. What I did not realise is how the intern table is represented. It appears it consists of a set of pages -- object arrays of 128 string elements -- that are created in the LOH. This is more evident in CDB/SOS: 0:000> .loadby sos mscorwks 0:000> !EEHeap -gc Number of GC Heaps: 1 generation 0 starts at 0x00f7a9b0 generation 1 starts at 0x00e79c3c generation 2 starts at 0x00b21000 ephemeral segment allocation context: none segment begin allocated size 00b20000 00b21000 010029bc 0x004e19bc(5118396) Large object heap starts at 0x01b21000 segment begin allocated size 01b20000 01b21000 01b8ade0 0x00069de0(433632) Total Size 0x54b79c(5552028) ------------------------------ GC Heap Size 0x54b79c(5552028) Taking a dump of the LOH segment reveals the pattern I saw in the leaking application: 0:000> !DumpHeap 01b21000 01b8ade0 ... 01b8a120 793040bc 528 01b8a330 00175e88 16 Free 01b8a340 793040bc 528 01b8a550 00175e88 16 Free 01b8a560 793040bc 528 01b8a770 00175e88 16 Free 01b8a780 793040bc 528 01b8a990 00175e88 16 Free 01b8a9a0 793040bc 528 01b8abb0 00175e88 16 Free 01b8abc0 793040bc 528 01b8add0 00175e88 16 Free total 1568 objects Statistics: MT Count TotalSize Class Name 00175e88 784 12544 Free 793040bc 784 421088 System.Object[] Total 1568 objects Note that the object array size is 528 (rather than 1056) because my workstation is 32 bit and the application server is 64 bit. The object arrays are still 128 elements long. So the moral to this story is to be very careful interning. If the string you are interning is not known to be a member of a finite set then your application will leak due to fragmentation of the LOH, at least in version 2 of the CLR. In our application's case, there is general code in the deserialisation code path that interns entity identifiers during unmarshalling: I now strongly suspect this is the culprit. However, the developer's intentions were obviously good as they wanted to make sure that if the same entity is deserialised multiple times then only one instance of the identifier string will be maintained in memory.

  • Dumping out Value on console using jQuery

    - by Rachel
    Hello, I come from PHP background and am used to doing var_dump, echo and print_r while doing some kind of debugging. I have just started on jquery, today is my first day infact and am trying to see if there is a way to dump out value to firebug console. Do we have similar function to var_dump or echo in jQuery or any other way to get values or debug statements displayed on the console ?

  • Problem with waveOutWrite and waveOutGetPosition deadlock

    - by MusiGenesis
    I'm working on an app that plays audio continuously using the waveOut... API from winmm.dll. The app uses "leapfrog" buffers, which are basically a bunch of arrays of samples that you dump into the audio queue. Windows plays them seamlessly in sequence, and as each buffer completes Windows calls a callback function. Inside this function, I load the next set of samples into the buffer, process them however, and then dump the buffer back into the audio queue. In this way, the audio plays indefinitely. For animation purposes, I'm trying to incorporate waveOutGetPosition into the application (since the "buffer done" callbacks are irregular enough to cause jerky animation). waveOutGetPosition returns the current position of playback, so it's hyper-precise. The problem is that in my application, making calls to waveOutGetPosition eventually causes the application to lock up - the sound stops and the call never returns. I've boiled things down to a simple app that demonstrates the problem. You can run the app here: http://www.musigenesis.com/SO/waveOut%20demo.exe If you just hear a tiny bit of piano over and over, it's working. It's just meant to demonstrate the problem. The source code for this project is here: http://www.musigenesis.com/SO/WaveOutDemo.zip The first button runs the app in leapfrog mode without making the calls to waveOutGetPosition. If you click this, the app will play forever without breaking (the X button will close it and shut it off). The second button starts the leapfrogger and also starts a forms timer that calls the waveOutGetPosition and displays the current position. Click this and the app will run for a short while and then lock up. On my laptop, it usually locks up in 15-30 seconds; at most it's taken a minute. I have no idea how to fix this, so any help or suggestions would be most welcome. I've found very few posts on this issue, but it seems that there is a potential deadlock, either from multiple calls to waveOutGetPosition or from calls to that and waveOutWrite that occur at the same time. It's possible that I'm calling this too frequently for the system to handle.

  • C#/.NET: Retrieving the contents/file attributes from a file inside a recycle bin

    - by eibhrum
    Hi, I just wanna ask if there's a possibility to retrieve the contents of a 'dump' file from the recycle bin programatically. The contents that I'm looking for are file attributes like 'Date Last Modified, 'Data created', 'size', etc (without restoring the file itself to the original location to preserve the original attributes found while inside the recycle bin.) Comments and suggestions are highly appreciated. Thanks.

  • Static Map API that supports HTTPS requests and is free

    - by gravyface
    Any options out there? Google Static Maps with SSL (HTTPS) is only available to Premier members. Bing's Open Map API seems to have the same restricts. Any other ideas? I'm debating whether to schedule a cronjob to wget over http and dump the images I need into a folder (named after the content object IDs that reference them), but I'd rather find a free map API (or something less klugey) that supports HTTPS requests.

  • Mysql password hashing method old vs new

    - by The Disintegrator
    I'm trying to connect to a mysql server at dreamhost from a php scrip located in a server at slicehost (two different hosting companies). I need to do this so I can transfer new data at slicehost to dreamhost. Using a dump is not an option because the table structures are different and i only need to transfer a small subset of data (100-200 daily records) The problem is that I'm using the new MySQL Password Hashing method at slicehost, and dreamhost uses the old one, So i get $link = mysql_connect($mysqlHost, $mysqlUser, $mysqlPass, FALSE); Warning: mysql_connect() [function.mysql-connect]: OK packet 6 bytes shorter than expected Warning: mysql_connect() [function.mysql-connect]: mysqlnd cannot connect to MySQL 4.1+ using old authentication Warning: mysql_query() [function.mysql-query]: Access denied for user 'nodari'@'localhost' (using password: NO) facts: I need to continue using the new method at slicehost and i can't use an older php version/library The database is too big to transfer it every day with a dump Even if i did this, the tables have different structures I need to copy only a small subset of it, in a daily basis (only the changes of the day, 100-200 records) Since the tables are so different, i need to use php as a bridge to normalize the data Already googled it Already talked to both support stafs The more obvious option to me would be to start using the new MySQL Password Hashing method at dreamhost, but they will not change it and i'm not root so i can't do this myself. Any wild idea? By VolkerK sugestion: mysql> SET SESSION old_passwords=0; Query OK, 0 rows affected (0.01 sec) mysql> SELECT @@global.old_passwords,@@session.old_passwords, Length(PASSWORD('abc')); +------------------------+-------------------------+-------------------------+ | @@global.old_passwords | @@session.old_passwords | Length(PASSWORD('abc')) | +------------------------+-------------------------+-------------------------+ | 1 | 0 | 41 | +------------------------+-------------------------+-------------------------+ 1 row in set (0.00 sec) The obvious thing now would be run a mysql SET GLOBAL old_passwords=0; But i need SUPER privilege to do that and they wont give it to me if I run the query SET PASSWORD FOR 'nodari'@'HOSTNAME' = PASSWORD('new password'); I get the error ERROR 1044 (42000): Access denied for user 'nodari'@'67.205.0.0/255.255.192.0' to database 'mysql' I'm not root... The guy at dreamhost support insist saying thet the problem is at my end. But he said he will run any query I tell him since it's a private server. So, I need to tell this guy EXACTLY what to run. So, telling him to run SET SESSION old_passwords=0; SET GLOBAL old_passwords=0; SET PASSWORD FOR 'nodari'@'HOSTNAME' = PASSWORD('new password'); grant all privileges on *.* to nodari@HOSTNAME identified by 'new password'; would be a good start?

  • Usage of Minidump within a COM Object

    - by nimo
    hi, I'm developing a COM dll which is an add-in to MSoffice. Since I'm not creating any logs within add-in I would like to add a crash report generator into my add-in. Hopefully 'Minidump' would be the best choice, but I have never use Minidump inside a COM object. I appreciate if somebody can point out possibilities of creating such crash dump with minidump inside a COM object. Thank You

  • How do i deserialize an object with pyYaml using safe_load?

    Having a snippet like this: import yaml class User(object): def __init__(self, name, surname): self.name= name self.surname= surname user = User('spam', 'eggs') serialized_user = yaml.dump(user) deserialized_user = yaml.load(serialized_user) print "name: %s, surname %s" % (deserialized_user.name, deserialized_user.surname) Yaml docs says that it is not safe to call yaml.load with any data received from an untrusted source; so, what do i need to modify to my snippet\class to use safe_load method? Is it possible?
