• segfault when cd-ing into certain directories in bash

  - by user84207

  I have noticed this very strange behavior recently. After cd into certain directories, I get a segfault on the terminal. --- SIGSEGV (Segmentation fault) @ 0 (0) --- --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV (core dumped) +++ segmentation fault (core dumped) I proceeded to strace a bash session in which I cd into the target directory, and was able to reproduce the problem. I attached the log to this pastebin: I paste below the few lines from the read of "cd stumpwm", which is the directory in question, until the segfault. I included a few of the repetitions of calls to "rt_sigprocmask" and "brk" to give a glimpse of the pattern, which occurs for most of the strace, read(0, cd stumpwm "c", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "d", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, " ", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "s", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "t", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "u", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "m", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "p", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "w", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "m", 1) = 1 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 read(0, "\n", 1) = 1 rt_sigprocmask(SIG_BLOCK, [INT], [], 8) = 0 ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig -icanon -echo ...}) = 0 ioctl(0, SNDCTL_TMR_STOP or TCSETSW, {B38400 opost isig icanon -echo ...}) = 0 ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon -echo ...}) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 rt_sigaction(SIGINT, {0x457d50, [], SA_RESTORER, 0x7ffff76254a0}, {0x49edc0, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGTERM, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGQUIT, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGALRM, {0x457f50, [HUP INT ILL TRAP ABRT BUS FPE USR1 SEGV USR2 PIPE ALRM TERM XCPU XFSZ VTALRM SYS], SA_RESTORER, 0x7ffff76254a0}, {0x49edc0, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGTSTP, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGTTOU, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGTTIN, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, {SIG_IGN, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGWINCH, {0x457920, [], SA_RESTORER, 0x7ffff76254a0}, {0x49e6e0, [], SA_RESTORER|SA_RESTART, 0x7ffff76254a0}, 8) = 0 rt_sigaction(SIGINT, {0x457d50, [], SA_RESTORER, 0x7ffff76254a0}, {0x457d50, [], SA_RESTORER, 0x7ffff76254a0}, 8) = 0 brk(0xa9a000) = 0xa9a000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0xa9b000) = 0xa9b000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0xa9c000) = 0xa9c000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0xa9d000) = 0xa9d000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0xa9e000) = 0xa9e000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0xa9f000) = 0xa9f000 brk(0xaa0000) = 0xaa0000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0xaa1000) = 0xaa1000 brk(0xaa2000) = 0xaa2000 (pattern of rt_sigprocmask, brk continues ...) rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0x1d5b000) = 0x1d5b000 brk(0x1d5c000) = 0x1d5c000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 brk(0x1d5d000) = 0x1d5d000 brk(0x1d5e000) = 0x1d5e000 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, [], 8) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV (core dumped) +++ segmentation fault (core dumped) How can I debug this? Is this likely to be a bash problem? The error does not occur with another shell, such as eshell. I have also run an fschk, although I haven't been able to see the output because of this bug.

40,000 and 1,500,000 numbers in the same range with and added _ and a 1-999 suffix numbers in the same range prefixed with BLA Each value is present exactly twice. There are no formula involved. I already checked for extra spaces. Immediately reapplying the Remove Duplicates command does not remove the remaining duplicate values. Reapplying the Remove Duplicates command after a reverse-sort seems to remove the remaining duplicates. Reverse-sorting before using the first Remove Duplicates changes the result (213 duplicate values removed and 387 unique values remained), only in the non-suffixed non-prefixed group. Can you reproduce this bug in Excel 2007 like I do? What triggers it? Could it the composite (numbers and text) data set? I'm not looking for alternatives. I want to know when not to use the feature and revert to already known (Excel 2003 era) alternatives.

  I have been struggling for the past few days with this problem: Basically, I want to send to a client browser a cookie of the form foo[sha1oftheurl]=[randomvalue] if and only if the cookie has not already been set. e.g. If a client browser requests "/page.html", the HTTP response will be like: resp.http.Set-Cookie = "foo4c9ae249e9e061dd6e30893e03dc10a58cc40ee6=ABCD;" then, if the same client request "/index.html", the HTTP response will contain a header: resp.http.Set-Cookie = "foo14fe4559026d4c5b5eb530ee70300c52d99e70d7=QWERTY;" In the end, the client browser will have 2 cookies: foo4c9ae249e9e061dd6e30893e03dc10a58cc40ee6=ABCD foo14fe4559026d4c5b5eb530ee70300c52d99e70d7=QWERTY Now, that, is not complicated in itself. The following code does it: import digest; import random; ##This vmod does not exist, it's just for the example. sub vcl_recv() { ## We compute the sha1 of the requested URL and store it in req.http.Url-Sha1 set req.http.Url-Sha1 = digest.hash_sha1(req.url); set req.http.random-value = random.get_rand(); } sub vcl_deliver() { ## We create a cookie on the client browser by creating a "Set-Cookie" header ## In our case the cookie we create is of the form foo[sha1]=[randomvalue] ## e.g for a URL "/page.html" the cookie will be foo4c9ae249e9e061dd6e30893e03dc10a58cc40ee6=[randomvalue] set resp.http.Set-Cookie = {""} + resp.http.Set-Cookie + "foo"+req.http.Url-Sha1+"="+req.http.random-value; } However, this code does not take into account the case where the Cookie already exists. I need to check that the Cookie does not exists before generating a random value. So I thought about this code: import digest; import random; sub vcl_recv() { ## We compute the sha1 of the requested URL and store it in req.http.Url-Sha1 set req.http.Url-Sha1 = digest.hash_sha1(req.url); set req.http.random-value = random.get_rand(); set req.http.regex = "abtest"+req.http.Url-Sha1; if(!req.http.Cookie ~ req.http.regex) { set req.http.random-value = random.get_rand(); } } The problem is that Varnish does not compute Regular expression at run time. Which leads to this error when I try to compile: Message from VCC-compiler: Expected CSTR got 'req.http.regex' (program line 940), at ('input' Line 42 Pos 31) if(req.http.Cookie !~ req.http.regex) { ------------------------------##############--- Running VCC-compiler failed, exit 1 VCL compilation failed One could propose to solve my problem by matching on the "abtest" part of the cookie or even "abtest[a-fA-F0-9]{40}": if(!req.http.Cookie ~ "abtest[a-fA-F0-9]{40}") { set req.http.random-value = random.get_rand(); } But this code matches any cookie starting by 'abtest' and containing an hexadecimal string of 40 characters. Which means that if a client requests "/page.html" first, then "/index.html", the condition will evaluate to true even if the cookie for the "/index.html" has not been set. I found in bug report phk or someone else stating that computing regular expressions was extremely expensive which is why they are evaluated during compilation. Considering this, I believe that there is no way of achieving what I want the way I've been trying to. Is there any way of solving this problem, other than writting a vmod? Thanks for your help! -Hugues

• iPhone doesn't save password for Cisco IPsec VPN using racoon daemon

  - by dsx

  On my Debian server I had set up racoon daemon (1:0.8.0-14) for Cisco IPSec VPN using certificates for authentication. My racoon.conf is like following: log info; path certificate "/etc/racoon/certs"; listen { isakmp $SERVER_IP_HERE [500]; isakmp_natt $SERVER_IP_HERE [4500]; } timer { natt_keepalive 10 sec; } remote anonymous { lifetime time 24 hours; proposal_check obey; passive on; exchange_mode aggressive,main; my_identifier asn1dn; peers_identifier asn1dn; verify_identifier on; certificate_type x509 "cert_name.crt" "key_name.key"; ca_type x509 "ca.crt"; mode_cfg on; verify_cert on; ike_frag on; generate_policy on; nat_traversal on; dpd_delay 20; proposal { encryption_algorithm aes; hash_algorithm sha1; authentication_method xauth_rsa_server; dh_group modp1024; } } mode_cfg { conf_source local; auth_source system; auth_throttle 3; save_passwd on; dns4 8.8.8.8; network4 $SOME_LAN_SUBNET; netmask4 255.255.255.0; pool_size 128; } sainfo anonymous { pfs_group 2; lifetime time 24 hour; encryption_algorithm aes; authentication_algorithm hmac_sha1; compression_algorithm deflate; } I'm not using PSK authentication here. Using iPhone configuration utility I had uploaded all required certificates to iPhone and set up VPN on demand. Everything works just fine except one thing: iPhone refuses to save VPN password regardless of save_passwd on; in racoon configuration file. As opposed to iPhone behaviour, Mac OS X 10.8.2 have no problems saving password. I had examined iPhone log file and found following: racoon[151] <Notice>: >>>>> phase change status = phase 1 established configd[50] <Notice>: IPSec Network Configuration started. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-ADDRESS = $SUBNET_IP_HERE. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-MASK = 255.255.255.0. configd[50] <Notice>: IPSec Network Configuration: SAVE-PASSWORD = 0. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-DNS = 8.8.8.8. configd[50] <Notice>: IPSec Network Configuration: BANNER = . configd[50] <Notice>: IPSec Network Configuration: DEF-DOMAIN = . configd[50] <Notice>: IPSec Network Configuration: DEFAULT-ROUTE = local-address $SUBNET_IP_HERE/32. configd[50] <Notice>: IPSec Phase2 starting. configd[50] <Notice>: IPSec Network Configuration established. configd[50] <Notice>: IPSec Phase1 established. Please note IPSec Network Configuration message containing SAVE-PASSWORD = 0.. Is it a bug in racoon daemon on server, or iPhone (iOS version is 6.0.1 (10A523)) or it is me missing something? How to make iPhone remember IPSec VPN password?

• I need to understand why my server turned off

  - by Dema

  Our organization was robbed and definitely it was inside job. I was set up. I work as a manager and as system administrator in this organization and everything goes against me. The only clue I have is that someone accidentally or intentionally turned of a server that is in the office indicating that some one was inside at the time that no one should be. This is the only evidence I have that can justify me.  I looked the log files and they show that the Power button was pressed. Can you help me to find out that that was not a bug or systems overheat? I will post the log files and if you will ask more I will gladly provide the information.

• Error during GENERAL_REQUEST_ENTITY for POST results in ASP .NET session state never getting unlocked

  - by Jesse

  I have been trying to chase down the root cause of a condition where ASP .NET session state remains locked after a web request has been terminated due to an unexpected error. We use the SQL Server session state provider for session because we have several servers in a web farm. This issue first presented itself in the form of many requests getting stuck on the 'AcquireRequestState' event of their lifecycle for no apparent reason. I was able to finding corresponding entries for these requests in the session state database in SQL server that were all locked (column Locked = 1). I was also able to correlate these requests to entries in the IIS log with HTTP status codes of 500 (with a sub status of 0). These findings lead me to believe that, in some cases, a request was erroring out but was NOT releasing its lock on session state like it should. I enabled Failed Request Tracing in IIS for the website in question for status code 500 with all available providers selected each with the 'Verbose' setting for verbosity. I've since gathered several failed traces that have caused permanently locked ASP .NET sessions. They all share the same characteristics: They are all 'POST' requests where the browser is posting data to be processed/saved. They all have events indicating that the 'Session' module was invoked during the REQUEST_ACQUIRE_STATE event. At this point the request would have marked the row in the session state database as being "locked". This is normal and expected. They all have GENERAL_READ_ENTITY_START, GENERAL_READ_ENTITY_END, and GENERAL_REQUEST_ENTITY entries that appear to be reading in the data that was posted to the server as part of the request. This appears to be a buffered operation as these events get repeated over and over with each one reading in some subset of the posted data. At some point during the 'read entity' related events and error occurs. Some have the error code "Incorrect function. (0x80070001)" and others have "The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)". Once the error has been encountered, they all jump directly to the END_REQUEST events. The issue here is that, under normal circumstances, there should be a RELEASE_REQUEST_STATE event that will allow the Session module to release the lock it has on the session. This event is being skipped in this scenario. Just to be sure, I enabled failed request tracing for the '200' status code as well and generated several traces of successful requests that do have the RELEASE_REQUEST_STATE event being handled by the Session module. My theory at this point is that some kind of network issue is causing the 'Incorrect function' and 'I/O operation has been aborted because of either a thread exit or an application request' errors, but I don't understand why this seems to be causing the request handling to skip over the RELEASE_REQUEST_STATE event. If the request went through REQUEST_ACQUIRE_STATE it seems like it should also hit RELEASE_REQUEST_STATE as well. I'm loathe to say that this is a bug in IIS or ASP .NET, but it certainly appears that way to me at this point. Are there any configuration changes I could make to help ensure that 'RELEASE_REQUEST_STATE' is fired under all error conditions?

• How to resolve high CPU + excessive stat("/etc/localtime") and clock_gettime(CLOCK_REALTIME) calls

I'm fresh out of ideas so any help/advice on how to diagnose or resolve would be greatly appreciated.

• How can I recover an ext4 filesystem corrupted after a fsck?

  - by Regan

  I have an ext4 filesystem on luks over software raid5. The filesystem was operating "just fine" for several years when I was beginning to run out of space. I had a 9T volume on 6x2T drives. I began upgrading to 3T drives by doing the mdadm fail, remove, add, rebuild, repeat process until I had a larger array. I then grew the luks container, and then when I unmounted and tried to resize2fs I was given the message the filesystem was dirty and needed e2fsck. Without thinking I just did e2fsck -y /dev/mapper/candybox and it began spewing all kinds of inode being removed type messages (can't remember exactly) I killed e2fsck and tried to remount the filesystem to backup data I was concerned about. When trying to mount at this point I get: # mount /dev/mapper/candybox /candybox mount: wrong fs type, bad option, bad superblock on /dev/mapper/candybox, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Looking back at my older logs I noticed the filesystem was giving this error each time the machine booted: kernel: [79137.275531] EXT4-fs (dm-2): warning: mounting fs with errors, running e2fsck is recommended So shame on me for not paying attention :( I then tried to mount using every backup superblock (one after another) and each attempt left this in my log: EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 0 failed (26534!=65440) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 1 failed (38021!=36729) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 2 failed (18336!=39845) ... EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 11911 failed (28743!=44098) BUG: soft lockup - CPU#0 stuck for 23s! [mount:2939] Attempts to restart e2fsck results in: # e2fsck /dev/mapper/candybox e2fsck 1.41.14 (22-Dec-2010) e2fsck: Group descriptors look bad... trying backup blocks... candy: recovering journal e2fsck: unable to set superblock flags on candy At this point, I decided it best to order some more drives and make an image using ddrescue Now two weeks later I have an image of the luks partition in a .img file. # ls -lh total 14T -rw-r--r-- 1 root root 14T Oct 25 01:57 candybox.img -rw-r--r-- 1 root root 271 Oct 20 14:32 candybox.logfile After numerous attempts using everything I could find online I could not coerce e2fsck to do anything on the image, so I used mkfs.ext4 -L candy candybox.img -m 0 -S and I was able to mount the dirty filesystem readonly without the journal and recover 960G of data. It gave all kinds of errors of various directories not existing and so forth but I was able to get some stuff. Which gave me some hope! I then ran e2fsck again and it had to recreate the root inode and gave a massive list of correcting group counts, I accepted the root inode creation and said no to everything else, leaving a completely empty filesystem. Re-ran again and said yes to all questions with the same result but now a "clean" but empty filesystem. extundelete gives me 0 recoverable inodes found. And now I'm stuck again, I can't come up with any other methods other than dropping to something like photorec which will give me an absolute mess with how large the filesystem was. I'm willing to re-copy the image from the original array and start over, if I can get any suggestions or ideas on a way to get more of my files back. I wish I could give more detailed logs of the commands that have run, but the output is long scrolled passed except for what gets logged to syslog and my memory is not as detailed due to the timeframe this has occurred over. Any help is greatly appreciated!

• Apache SSL reverse proxy to a Embed Tomcat

• MySQL reserves too much RAM

  - by Buddy

  I have a cheap VPS with 128Mb RAM and 256Mb burst. MySQL starts and reserves about 110Mb, but uses not more than 20Mb of them. My VPS Control Panel shows, that I use 127Mb (I also running nginx and sphinx), I know, that it shows reserved RAM, but when I reach over 128Mb, my VPS reboots automatically every 4 hours. So I want to force MySQL to reserve less RAM. How can i do that? I did some tweaks with my.conf but it helped not so much. top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1 root 15 0 2156 668 572 S 0.0 0.3 0:00.03 init 11311 root 15 0 11212 356 228 S 0.0 0.1 0:00.00 vzctl 11312 root 18 0 3712 1484 1248 S 0.0 0.6 0:00.01 bash 11347 root 18 0 2284 916 732 R 0.0 0.3 0:00.00 top 13978 root 17 -4 2248 552 344 S 0.0 0.2 0:00.00 udevd 14262 root 15 0 1812 564 472 S 0.0 0.2 0:00.03 syslogd 14293 sphinx 15 0 11816 1172 672 S 0.0 0.4 0:00.07 searchd 14305 root 25 0 7192 1036 636 S 0.0 0.4 0:00.00 sshd 14321 root 25 0 2832 836 668 S 0.0 0.3 0:00.00 xinetd 15389 root 18 0 3708 1300 1132 S 0.0 0.5 0:00.00 mysqld_safe 15441 mysql 15 0 113m 16m 4440 S 0.0 6.4 0:00.15 mysqld 15489 root 21 0 13056 1456 340 S 0.0 0.6 0:00.00 nginx 15490 nginx 18 0 13328 2388 992 S 0.0 0.9 0:00.06 nginx 15507 nginx 25 0 19520 5888 4244 S 0.0 2.2 0:00.00 php-cgi 15508 nginx 18 0 19636 4876 2748 S 0.0 1.9 0:00.12 php-cgi 15509 nginx 15 0 19668 4872 2716 S 0.0 1.9 0:00.11 php-cgi 15518 root 18 0 4492 1116 568 S 0.0 0.4 0:00.01 crond MySQL tuner: >> MySQLTuner 1.0.1 - Major Hayden <[email protected]> >> Bug reports, feature requests, and downloads at http://mysqltuner.com/ >> Run with '--help' for additional options and output filtering Please enter your MySQL administrative login: root Please enter your MySQL administrative password: -------- General Statistics -------------------------------------------------- [--] Skipped version check for MySQLTuner script [OK] Currently running supported MySQL version 5.0.77 [OK] Operating on 32-bit architecture with less than 2GB RAM -------- Storage Engine Statistics ------------------------------------------- [--] Status: -Archive -BDB -Federated +InnoDB -ISAM -NDBCluster [--] Data in InnoDB tables: 1M (Tables: 1) [OK] Total fragmented tables: 0 -------- Performance Metrics ------------------------------------------------- [--] Up for: 38m 43s (37 q [0.016 qps], 20 conn, TX: 4M, RX: 3K) [--] Reads / Writes: 100% / 0% [--] Total buffers: 28.1M global + 832.0K per thread (100 max threads) [OK] Maximum possible memory usage: 109.4M (42% of installed RAM) [OK] Slow queries: 0% (0/37) [OK] Highest usage of available connections: 1% (1/100) [OK] Key buffer size / total MyISAM indexes: 128.0K/64.0K [OK] Query cache efficiency: 42.1% (8 cached / 19 selects) [OK] Query cache prunes per day: 0 [!!] Temporary tables created on disk: 27% (3 on disk / 11 total) [!!] Thread cache is disabled [OK] Table cache hit rate: 57% (8 open / 14 opened) [OK] Open file limit used: 1% (12/1K) [OK] Table locks acquired immediately: 100% (22 immediate / 22 locks) [!!] Connections aborted: 10% [OK] InnoDB data size / buffer pool: 1.5M/8.0M -------- Recommendations ----------------------------------------------------- General recommendations: MySQL started within last 24 hours - recommendations may be inaccurate Enable the slow query log to troubleshoot bad queries When making adjustments, make tmp_table_size/max_heap_table_size equal Reduce your SELECT DISTINCT queries without LIMIT clauses Set thread_cache_size to 4 as a starting value Your applications are not closing MySQL connections properly Variables to adjust: tmp_table_size (> 32M) max_heap_table_size (> 16M) thread_cache_size (start at 4) I think if I do what MySQLtuner says, MySQL will use more RAM.

I set up some docker containers, configured 6in4 tunnel server and IPv6 forwarding on the Linode: # uname -a Linux argo 3.15.4-x86_64-linode45 #1 SMP Mon Jul 7 08:42:36 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux # ip addr .. snipped .. 48: sit-sapikachu: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1472 qdisc noqueue state UNKNOWN group default link/sit 106.185.41.115 peer 1.2.3.4 inet6 fd00::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::6ab9:2973/64 scope link valid_lft forever preferred_lft forever 13: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff inet 172.17.42.1/16 scope global docker0 valid_lft forever preferred_lft forever inet6 fc00::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::5484:7aff:fefe:9799/64 scope link valid_lft forever preferred_lft forever // Docker containers are bridged to docker0 On my local box, I configured a 6in4 tunnel interface to connect to the Linode box, and added a host route to one of the docker container: # uname -a Linux sapikachu-netbox 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux # ip addr .. snipped .. 16: sit-argo: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN group default link/sit 0.0.0.0 peer 106.185.41.115 inet6 fd00::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::a97:302/64 scope link valid_lft forever preferred_lft forever inet6 fe80::ac19:1/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:1f0/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:1fa/64 scope link valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether *** brd ff:ff:ff:ff:ff:ff .. snipped .. inet6 fd00:0:1::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::2e0:6fff:fe0e:365e/64 scope link valid_lft forever preferred_lft forever # ip route replace fc00::1875:8606:d8c1:8a9d via fd00::1 # Add route to docker container # ip -6 route .. snipped unrelated routes fc00::1875:8606:d8c1:8a9d via fd00::1 dev sit-argo metric 1024 expires 590sec mtu 1472 fd00::/64 dev sit-argo proto kernel metric 256 fd00:0:1::/64 dev eth0 proto kernel metric 256 fe80::/64 dev sit-argo proto kernel metric 256 (Note that tunnel MTU on my local box is different from the server, this is intentional for testing) After adding the host route to the docker container (fc00::1875:8606:d8c1:8a9d), I can ping the container without problem until the route expires. After that I couldn't get reply any more. If I run ip -6 route in a few seconds after expiration, expiration time of the host route will be a negative number: fc00::1875:8606:d8c1:8a9d via fd00::1 dev sit-argo metric 1024 expires -1sec And output of ip route get fc00::1875:8606:d8c1:8a9d shows that it is routed to my default IPv6 gateway (which fails to route it correctly of course, since the address is not globally routable). After some time, the host route disappears without a trace. This problem won't happen if I do either one of the following things: Set MTU of tunnel on my local box to be the same as the server (1472). The route won't have expiration time in both ip -6 route and ip route get in this case. Instead of adding a host route, add a route with network mask (even /127 works). In this case ip -6 route shows the route without expiration time, ip route get shows expiration time but it will be correctly refreshed after expiration. Although this problem can be easily resolved, I am curious to know why this happens. Is there error in my configuration, or is this a kernel bug?

• mySQL Optimization Suggestions

  - by Brian Schroeter

  I'm trying to optimize our mySQL configuration for our large Magento website. The reason I believe that mySQL needs to be configured further is because New Relic has shown that our SELECT queries are taking a long time (20,000+ ms) in some categories. I ran MySQLTuner 1.3.0 and got the following results... (Disclaimer: I restarted mySQL earlier after tweaking some settings, and so the results here may not be 100% accurate): >> MySQLTuner 1.3.0 - Major Hayden <[email protected]> >> Bug reports, feature requests, and downloads at http://mysqltuner.com/ >> Run with '--help' for additional options and output filtering [OK] Currently running supported MySQL version 5.5.37-35.0 [OK] Operating on 64-bit architecture -------- Storage Engine Statistics ------------------------------------------- [--] Status: +ARCHIVE +BLACKHOLE +CSV -FEDERATED +InnoDB +MRG_MYISAM [--] Data in MyISAM tables: 7G (Tables: 332) [--] Data in InnoDB tables: 213G (Tables: 8714) [--] Data in PERFORMANCE_SCHEMA tables: 0B (Tables: 17) [--] Data in MEMORY tables: 0B (Tables: 353) [!!] Total fragmented tables: 5492 -------- Security Recommendations ------------------------------------------- [!!] User '@host5.server1.autopartsnetwork.com' has no password set.

• need assistance with my.cnf - 1500% CPU usage

  - by Alan Long

  I'm running into a few issues with our new database server. It is a HP G8 with 2 INTEL XEON E5-2650 processors and 32GB of ram. This server is dedicated as a MySQL server (5.1.69) for our intranet portal. I have been having issues with this server staying alive - I notice high CPU usage during certain times of day (8% ~ 1500%+) and see very low memory usage (7 ~ 15%) based on using the 'top' command. When the CPU usage passes 1000%, that is when the app usually dies. I'm trying to see what I'm doing wrong with the config file, hopefully one of the experts can chime in and let me know what they think.

• Please verify my layout: bottom button keeps coming up over keyboard

• Trac vs. Redmine vs. JIRA vs. FogBugz for one-man shop?

  - by kizzx2

  Background I am a one-man freelancer looking for a project management software that can provide the following requirements. I have used Trac for about a year now. Tried Redmine and FogBugz on Demand for a couple of weeks. Never tried JIRA before. Basically, I'm looking for a piece of software that: Facilitates developer-client communication/collaboration Does time tracking Requirements Record time estimates/Time tracking Clients must be able to create/edit his own tickets/cases Clients must not see Developer created tickets/cases (internal) Affordable (price) with multiple clients Nice-to-haves Supports multiple projects in one installation Free eclipse integration (Mylyn) Easy time-tracking without using the Web UI (Trac's post commit hook or Redmine's commit message scanning) Clients can access the Wiki Export the data to standard formats My evaluation Trac can basically fulfill most of the above requirements, but with lots of customizations and plug-ins that it doesn't feel so clean. One downside is that the main trunk (0.11) has been around for a year or more and I still haven't seen much tendency of any upgrades coming up. Redmine has the cleanest Web UI. It's design philosophy seems to be the most elegant, with its innovative commit message scanning and stuff. However, the current version doesn't seem to be very mature and stable yet. It doesn't support internal (private) tickets and the time-tracking commit message patch doesn't support the trunk version. The good thing about it is that the main trunk still seems to be actively developed. FogBugz is actually a very well written piece of software. However the idea of paying $25/month for the client to be able to log-in to the system seems a little bit too far off for an individual developer. The free version supports letting clients create/view their own cases using email, which is a sub-optimal alternative to having a full-fledged list of the user's own cases. That also means clients can't read/write wiki pages. Its time-tracking approach is innovative and good though. However the fact that all the eclipse integration (Bugclipse, Foglyn) are commercial. Yet other investments before I can use my bug-tracker! If I revert back to the Web UI, it's not really a fast rendering Web service. Also, the in-built report functions are excellent (e.g. evidence based scheduling) JIRA is something I have zero experience with. Can someone with JIRA experience recommend why it might be a good fit for this particular situation? Question Can we share experience on this? Any specific plugins/customizations would that would best suit the requirements for this case?

• Why SetUnhandledExceptionFilter cannot capture some exception but AddVectoredExceptionHandler can do

  - by wrongite

  I have experienced a problem that the function I passed to the SetUnhandledExceptionFilter didn't get called when the exception code c0000374 raising. But it works fine with the exception code c0000005. Then I tried to use the AddVectoredExceptionHandler instead, and it didn't have the problem, the handler function get called correctly. Is it the API bug? Can I use AddVectoredExceptionHandler instead of SetUnhandledExceptionFilter everywhere? The both functions work correctly with // Exception code c0000005 int* p1 = NULL; *p1 = 99; Only AddVectoredExceptionHandler can capture this exception. // Exception code c0000374 int* p2 = new int; delete p2; delete p2; Test program. #include <tchar.h> #include <fstream> #include <Windows.h> LONG WINAPI VectoredExceptionHandler(PEXCEPTION_POINTERS pExceptionInfo) { std::ofstream f; f.open("VectoredExceptionHandler.txt", std::ios::out | std::ios::trunc); f << std::hex << pExceptionInfo->ExceptionRecord->ExceptionCode << std::endl; f.close(); return EXCEPTION_CONTINUE_SEARCH; } LONG WINAPI TopLevelExceptionHandler(PEXCEPTION_POINTERS pExceptionInfo) { std::ofstream f; f.open("TopLevelExceptionHandler.txt", std::ios::out | std::ios::trunc); f << std::hex << pExceptionInfo->ExceptionRecord->ExceptionCode << std::endl; f.close(); return EXCEPTION_CONTINUE_SEARCH; } int _tmain(int argc, _TCHAR* argv[]) { AddVectoredExceptionHandler(1, VectoredExceptionHandler); SetUnhandledExceptionFilter(TopLevelExceptionHandler); // Exception code c0000374 int* p2 = new int; delete p2; delete p2; // Exception code c0000005 int* p1 = NULL; *p1 = 99; return 0; }

• Visual Studio build fails: unable to copy exe-file from obj\debug to bin\debug

  - by Nailuj

  This is a question asked before, both here on Stack Overflow and other places, but none of the suggestions I've found this far has helped me, so I just have to try asking a new question. Scenario: I have a simple Windows Forms application (C#, .NET 4.0, Visual Studio 2010). It has a couple of base forms that most other forms inherit from, it uses Entity Framework (and POCO classes) for database access. Nothing fancy, no multi-threading or anything. Problem: All was fine for a while. Then, all out of the blue, Visual Studio failed to build when I was about to launch the application. I got the warning "Unable to delete file '...bin\Debug\[ProjectName].exe'. Access to the path '...bin\Debug\[ProjectName].exe' is denied." and the error "Unable to copy file 'obj\x86\Debug\[ProjectName].exe' to 'bin\Debug\[ProjectName].exe'. The process cannot access the file 'bin\Debug\[ProjectName].exe' because it is being used by another process." (I get both the warning and the error when running Rebuild, but only the error when running Build - don't think that is relevant?) I understand perfectly fine what the warning and error message says: Visual Studio is obviously trying to overwrite the exe-file while it the same time has a lock on it for some reason. However, this doesn't help me find a solution to the problem... The only thing I've found working is to shut down Visual Studio and start it again. Building and launching then works, untill I make a change in some of the forms, then I have the same problem again and have to restart... Quite frustrating! As I mentioned above, this seems to be a known problem, so there are lots of suggested solutions. I'll just list what I've already tried here, so people know what to skip: Creating a new clean solution and just copy the files from the old solution. Adding the following to the following to the project's pre-build event: if exist "$(TargetPath).locked" del "$(TargetPath).locked"   if not exist "$(TargetPath).locked" if exist "$(TargetPath)" move "$(TargetPath)" "$(TargetPath).locked" Adding the following to the project properties (.csproj file): <GenerateResourceNeverLockTypeAssembliestrue</GenerateResourceNeverLockTypeAssemblies However, none of them worked for me, so you can probably see why I'm starting to get a bit frustrated. I don't know where else to look, so I hope somebody has something to give me! Is this a bug in VS, and if so is there a patch? Or has I done something wrong, do I have a circular reference or similar, and if so how could I find out? Any suggestions are highly appreciated :)

• WPF CommandParameter is NULL first time CanExecute is called

  - by Jonas Follesø

  I have run into an issue with WPF and Commands that are bound to a Button inside the DataTemplate of an ItemsControl. The scenario is quite straight forward. The ItemsControl is bound to a list of objects, and I want to be able to remove each object in the list by clicking a Button. The Button executes a Command, and the Command takes care of the deletion. The CommandParameter is bound to the Object I want to delete. That way I know what the user clicked. A user should only be able to delete their "own" objects - so I need to do some checks in the "CanExecute" call of the Command to verify that the user has the right permissions. The problem is that the parameter passed to CanExecute is NULL the first time it's called - so I can't run the logic to enable/disable the command. However, if I make it allways enabled, and then click the button to execute the command, the CommandParameter is passed in correctly. So that means that the binding against the CommandParameter is working. The XAML for the ItemsControl and the DataTemplate looks like this: <ItemsControl x:Name="commentsList" ItemsSource="{Binding Path=SharedDataItemPM.Comments}" Width="Auto" Height="Auto"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Button Content="Delete" FontSize="10" Command="{Binding Path=DataContext.DeleteCommentCommand, ElementName=commentsList}" CommandParameter="{Binding}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> So as you can see I have a list of Comments objects. I want the CommandParameter of the DeleteCommentCommand to be bound to the Command object. So I guess my question is: have anyone experienced this problem before? CanExecute gets called on my Command, but the parameter is always NULL the first time - why is that? Update: I was able to narrow the problem down a little. I added an empty Debug ValueConverter so that I could output a message when the CommandParameter is data bound. Turns out the problem is that the CanExecute method is executed before the CommandParameter is bound to the button. I have tried to set the CommandParameter before the Command (like suggested) - but it still doesn't work. Any tips on how to control it. Update2: Is there any way to detect when the binding is "done", so that I can force re-evaluation of the command? Also - is it a problem that I have multiple Buttons (one for each item in the ItemsControl) that bind to the same instance of a Command-object? Update3: I have uploaded a reproduction of the bug to my SkyDrive: http://cid-1a08c11c407c0d8e.skydrive.live.com/self.aspx/Code%20samples/CommandParameterBinding.zip

• Doing TDD Silverlight 4 RC using Visual Studio 2010 RC

  - by user133992

  First I am glad to see better TDD support in VS2010. Support for generating code stubs from my tests is ok - not as good as more mature TDD plug-ins but a good start. I am looking for some best Silverlight 4.0 TDD practices. First Question: Anyone have links, recommendations? I know the new Silverlight Unit Test capabilities are much better (Jeff Wilcox's Mix Presentation). What I am focusing on right now is using TDD to develop pure Silverlight 4.0 Class Library projects - projects without a Silverlight UI project. I've been able to get it to work but not as cleanly as it should be. I can create an Empty VS project. Add A Silverlight 4 Class Library Project. Add a TestProject (not a silverlight Unit Test Project but a plain Test Project). Add a simple test in the Test Project such as: namespace Calculator.Test { [TestClass] public class CalculatorTests { [TestMethod] public void CalulatorAddTest() { Calc c = new Calc(); int expected = 10; int actual = c.Add(6, 4); Assert.AreEqual<int>(expected, actual); } } } Using the new Generate Type and Method from Test feature it will generate the following code in the Silverlight Project: namespace Calculator { public class Calc { public int Add(int p, int p_2) { throw new NotImplementedException(); } } } When I run the tests the first time it says the target assembly is Silverlight and not able to run test - Not exact text but the same general idea. When I change the implementation to: namespace Calculator { public class Calc { public int Add(int p, int p_2) { return p + p_2; } } } and re-run the test, it works fine and the test goes green. It also works for all other TDD code I generate after. I also get a warning Mark in the Test Project's reference to the Calculator Silverlight Class Library Assembly. Second Question: Any comments ideas if this just a bug in VS2010 RC or is Silverlight Class Library TDD not really supported. I have not created a Silverlight UI project or changed and build or debug settings so I have no idea what is hosting the silverlight DLL. Finally, some of the Silverlight Class Libraries I need to write will provide functionality that requires elevated Out-Of-Browser rights. Based on the above, it looks like I can use TDD Test Projects against regular Silverlight 4.0 Class Libraries, but I have no idea how I can TDD the elevated OOB functionality without also creating the UI component that gets installed. The UI piece is not really needed for the Library development and gets in the way of what I actually want to TDD. I know I can (and will) mock some of that functionality but at some point I will also need the real thing in my tests. Third Question: Any ideas how to TDD Silverlight 4.0 Class Library project that requires OOB elevated rights? Thanks!

• CSS3 Gradients to reproduce an 'inner glow' effect from Illustrator with border-radius applied

  - by iamfriendly

  Hello all! First post on here so please be kind :) I am in the process of trying to get my head properly around CSS3 Gradients (specifically radial ones) and in doing so I think I've set myself a relatively tough challenge. In Adobe Illustrator I have created a 'button' style which can be seen here: http://bit.ly/aePPtV (jpg image). To create this image I created a rectangle with a background colour of rgb(63,64,63) or #3F403F, then 'stylized' it to have a 15px border radius. I then applied an 'inner glow' to it with a 25% opacity, 8px blur, white from the center. Finally, I applied a 3pt white stroke on it. (I'm telling you all of this in case you wished to reproduce it, if the image above isn't sufficient.) So, my question is thus: is it possible to recreate this 'button' using CSS without the need for an image? I am aware of the 'limitations' of Internet Explorer (and for the sake of this experiment, I couldn't give a monkeys). I am also aware of the small 'bug' in webkit which incorrectly renders an element with a background colour, border-radius and a border (with a different color to the background-color) - it lets the background color bleed through on the curved corners. My best attempt so far is fairly pathetic, but for reference here is the code: section#featured footer p a { color: rgb(255,255,255); text-shadow: 1px 1px 1px rgba(0,0,0,0.6); text-decoration: none; padding: 5px 10px; border-radius: 15px; -moz-border-radius: 15px; -webkit-border-radius: 15px; border: 3px solid rgb(255,255,255); background: rgb(98,99,100); background: -moz-radial-gradient( 50% 50%, farthest-side, #626364, #545454 ); background: -webkit-gradient( radial, 50% 50%, 1px, 50% 50%, 5px, from(rgb(98,99,100)), to(rgb(84,84,84)) ); } Basically, terrible. Any hints or tips gratefully accepted and thank you very much in advance for them!

• MetadataType, inherited properties and client validation in ASP.NET MVC 2

  - by Kristoffer Ahl

  Inherited properties and MetadataType does not seem to work with client side validation in ASP.NET MVC 2. The validation of our MetadataTypes work as expected on the server but for some reason it does not generate the appropriate client scripts for it. Client side validation kicks in as expected for properties with the DataAnnotations attributes set on the PersonView so I know that client side validation is active and that it works. Does anyone know if or how it can be fixed? Here's what we have: public abstract class PersonView { public string FirstName { get; set; } public string LastName { get; set; } public string Email { get; set; } [Required] public string PhoneNumber { get; set; } public string AddressLine1 { get; set; } public string AddressLine2 { get; set; } public string AddressZipCode { get; set; } public string AddressCity { get; set; } public string AddressCountry { get; set; } } [MetadataType(typeof(CustomerViewMetaData))] public class CustomerView : PersonView {} [MetadataType(typeof(GuestViewMetaData))] public class GuestView : PersonView {} public class GuestViewMetaData { [Required(ErrorMessage = "The guests firstname is required")] public string FirstName { get; set; } [Required(ErrorMessage = "The guests lastname is required")] public string LastName { get; set; } } public class CustomerViewMetaData { [Required(ErrorMessage = "The customers firstname is required")] public string FirstName { get; set; } [Required(ErrorMessage = "The customers lastname is required")] public string LastName { get; set; } [Required(ErrorMessage = "The customers emails is required")] public string Email { get; set; } } As you can see, it's nothing fancy or strange in there... Can it be fixed? Is it a bug in ASP.NET MVC 2?
