ZODB storage errors ...during object abort
by iroro 25 Jan '05

25 Jan '05

Hi, I'm investigating some nasty hangs/freezes that seem to occur every 2-3 days. Usually, i just "service zope restart" and I'm back in business. So I turned on event logging on the last restart to help figure this out and Zope hasn't hung yet, but I've been seeing these nasty looking errors (esp. "This shouldn't happen") any ideas, hints, debugging paths that might shed some light on this error would be greatly appreciated!!! thanks, io --- <snip from Zope event log> ------ 2005-01-24T01:00:33 ERROR(200) ZODB A storage error occured during object abort. This shouldn't happen. Traceback (innermost last): File /var/local/zope-2.6.4/lib/python/ZODB/Transaction.py, line 401, in _commit_error File /var/local/zope-2.6.4/lib/python/Shared/DC/ZRDB/TM.py, line 60, in abort File /var/local/zope/lib/python/Products/ZMySQLDA/db.py, line 405, in _abort

epoz and zpt
by Milos Prudek 25 Jan '05

25 Jan '05

Could someone please post the simplest working example of Epoz in ZPT? An example that would edit a file called 'text'. The following code I figured out works but it does not save to a file: ZPT method /epoz/a: <form action="/epoz/a" method="post"> <span tal:define="text here/text|string:" tal:replace="structure python: here.Epoz('text', data=text, toolbox='/', lang='en', style='width: 620px; height: 250px; border: 1px solid #000000;')" /> <input type="submit" name="submit" value=" Save Changes " > </form> What's wrong with my example? -- Milos Prudek

I'm back in business. A list post from 1999 (by Amos) tipped me to the likely cause: something must have changed with the dns server specified in my zope.conf (start.py at the time). I reverted to the default (unset). Cheers Ken __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Yes, thanks, I have backups. And I forgot to mention, I am running Zope 2.7.3/FreeBSD 4.9. Actually, I suspect it is not strictly a Zope problem. Squid (which I stopped) was running fine, and I was able to reboot the machine (remotely) with no effect. My ISP-friend, who gets to work in about 6 hours, may (or may not) be able to help with any admin-type issues, so any help from the list will be much appreciated.

Hi, Something went wrong with my Zope overnight. I attempted to restart this morning, but Zope dies after serving a single page. Strangely, although I can retrieve one page, there is no entry for it in Z2.log.

MySQL Windows Driver Updates
by hpinson＠indepthl.com 25 Jan '05

25 Jan '05

Have Zope MySQL database drivers (ZMySQLDA and DB) and ODBC (ZODBCDA) development been abandoned for the Windows platform? Most of what I can find is very out of date (no longer works with the current release), experimental (with major problems), or commercial. My need is to hook Zope 2.7.4 up to MySQL 4.0.16. on a W2K server. My preference would be the native driver. At this point, it looks like the eGenix commercial solution may be ony viable option, and I really have no idea how good it is. If anyone has gotten this MySQLDA mess working in such an environment, I would be grateful to know how you did it.

Re: Problem with external method locking threads
by David Swift 25 Jan '05

25 Jan '05

Please belay this problem - it actually appears to be a problem with my choice of regular expression. the 'fileLink' regexp in the script goes into never-neverland for some links that have query strings containing links. Once in this state, Python has to be killed to stop it. Who'da thought infinite recursion could take so long... David

Problem with external method locking threads
by David Swift 24 Jan '05

24 Jan '05

I am running an External method, to fix some hard links in our ZWiki back to relative links. On two of our three ZWikis, this script runs well. On the third ZWiki, which has about 530 pages, this script causes the Zope instance to stop responding to any requests, after it processes about 140 pages. I have tried deleting the pages it freezes on, but it still freezes at about the same place each time. After examing the lists, and running strace, I am certain that one of the Python/Zope threads refuses to respond to SIGRTMIN, and then somehow locks up all threads - however, this is deeper than my knowledge goes, and I am hoping someone on this list can point me towards solutions I have not yet tried. My environment is: 2.5Ghz Intel single processor 1GB RAM Fedora 1 kernel - Linux our.server.com 2.4.22-1.2199.nptl #1 Wed Aug 4 12:21:48 EDT 2004 i686 i686 i386 GNU/Linux Software RAID 1, using a 36GB partition for Data.fs. Directory instance/var is a symlink to this partition. Python 2.3.3 and Python 2.4 Zope 2.7.3 ZWiki ZWiki-0-37-0 glibc-2.3.4-3 Below, I have copied: The External Method script I am using A brief description of the various things I have tried A sample of the environment, from within zopectl A copy of the strace run I am getting during script execution I use the command 'setuidgid zope bin/zopectl' to run the Zope instance. Any help is greatly appreciated! David -------------------- The script looks like this: from StringIO import StringIO import zLOG import re def addpage(self,o): """ Given a file or image, convert links to LocalFS """ nid = o.getId() fileOnlyLink = re.compile(r'href=\"([- .\w]+\.\w+)\"') fileLink = re.compile(r'https://zwiki(?:.*?/)+?([- .%\w]+.\w+)"') otherLink = re.compile(r'https://zwiki(?:.*?/)+([- %\w]+)"') pageText = o.read() pageText = fileOnlyLink.sub(r'href="uploads/\1"', pageText) pageText = fileLink.sub(r'uploads/\1"', pageText) pageText = otherLink.sub(r'\1"', pageText) o.setText(pageText) zLOG.LOG('addpage', zLOG.WARNING, 'working on %s' % nid) o.reindex_object() -------------------- tried Python 2.4 and Zope 2.7.3-0 tried Python 2.3.3 and Zope 2.7.3-0 tried refreshing glibc, to version glibc-2.3.4-3 tried LD_ASSUME_KERNEL=2.4.1 in runzope and zopectl tried LD_ASSUME_KERNEL=2.2.5 in runzope and zopectl tried deleting data for pages it stops on tried THREAD_STACK_SIZE of 0x20000 when compiling Python tried compiling Python with ./configure --prefix=/usr/local/python-2.4 --with-threads --with-signal-module --with-libs='rt' tried compiling Python with ./configure --prefix=/usr/local/python-2.4 --with-threads --with-signal-module tried compiling Python with ./configure --prefix=/usr/local/python-2.4 --with-threads tried compiling Python with ./configure --prefix=/usr/local/python-2.3.3 --with-threads --with-signal-module --with-libs='rt' tried compiling Python with ./configure --prefix=/usr/local/python-2.3.3 --with-threads --with-signal-module tried compiling Python with ./configure --prefix=/usr/local/python-2.3.3 --with-threads -------------------- environment of zopectl zopectl> stop . . . . . . . . . . . daemon process stopped zopectl> shell bash: /root/.bashrc: Permission denied bash-2.05b$ set BASH=/bin/bash BASH_ENV=/root/.bashrc BASH_VERSINFO=([0]="2" [1]="05b" [2]="0" [3]="1" [4]="release" [5]="i386-redhat-linux-gnu") BASH_VERSION='2.05b.0(1)-release' CLIENT_HOME=/usr/local/zope/apmindsf/var COLUMNS=140 DIRSTACK=() EUID=88 GROUPS=() G_BROKEN_FILENAMES=1 HISTFILE=/root/.bash_history HISTFILESIZE=1000 HISTSIZE=1000 HOME=/root HOSTNAME=rope.apmindsf.com HOSTTYPE=i386 IFS=$' \t\n' INPUTRC=/etc/inputrc INSTANCE_HOME=/usr/local/zope/apmindsf LANG=en_US.UTF-8 LD_ASSUME_KERNEL=2.4.1 LESSOPEN='|/usr/bin/lesspipe.sh %s' LINES=61 LOGNAME=root MACHTYPE=i386-redhat-linux-gnu MAIL=/var/spool/mail/root MAILCHECK=60 OPTERR=1 OPTIND=1 OSTYPE=linux-gnu PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin PPID=8735 PS1='\s-\v\$ ' PS2='> ' PS4='+ ' PWD=/usr/local/zope/apmindsf PYTHONPATH=/usr/local/zope/lib/python SHELL=/bin/bash SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor SHLVL=3 SOFTWARE_HOME=/usr/local/zope/lib/python SSH_CLIENT='192.168.1.20 3660 22' SSH_CONNECTION='192.168.1.20 3660 192.168.1.72 22' SSH_TTY=/dev/pts/1 TERM=cygwin UID=88 USER=root USERNAME=root ZMANAGED=1 ZOPE_HOME=/usr/local/zope _=/bin/bash bash-2.05b$ -------------------- strace of script execution [root@server Python-2.4]# strace -s2000 -p 8738 Process 8738 attached - interrupt to quit select(9, [3 4 8], [], [3 4 8], {4, 460000}) = 0 (Timeout) select(9, [3 4 8], [], [3 4 8], {30, 0}) = 1 (in [3], left {12, 590000}) accept(3, {sa_family=AF_INET, sin_port=htons(3429), sin_addr=inet_addr("192.168.1.20")}, [16]) = 14 fcntl64(14, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(14, F_SETFL, O_RDWR|O_NONBLOCK) = 0 getpeername(14, {sa_family=AF_INET, sin_port=htons(3429), sin_addr=inet_addr("192.168.1.20")}, [16]) = 0 gettimeofday({1106285562, 100163}, NULL) = 0 fcntl64(14, F_SETFD, FD_CLOEXEC) = 0 select(15, [3 4 8 14], [], [3 4 8 14], {30, 0}) = 1 (in [14], left {30, 0}) recv(14, "GET /am/convertLinks2local/ZScriptHTML_tryForm HTTP/1.1\r\nHost: our.server.com:8080\r\nUser-Agent: Mozilla/5.0 (Windows; U; Wi ndows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0\r\nAccept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/pla in;q=0.8,image/png,*/*;q=0.5\r\nAccept-Language: en-us,en;q=0.5\r\nAccept-Encoding: gzip,deflate\r\nAccept-Charset: ISO-8859-1,utf-8;q=0.7,* ;q=0.7\r\nKeep-Alive: 300\r\nConnection: keep-alive\r\nReferer: http://our.server.com:8080/am/convertLinks2local/ZPythonScriptHTML_editFo rm\r\nCookie: tree-s=\"eJzTyCkw5NLIKTDiClZ3hANXW3WuAmOuxEQ9AIOOB9Q\"\r\nAuthorization: Basic ZHN3aWZ0OjR0aGZsMDBy\r\n\r\n", 4096, 0) = 643 gettimeofday({1106285562, 102930}, NULL) = 0 kill(8744, SIGRTMIN) = 0 kill(8744, SIGRTMIN) = 0 rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0 rt_sigsuspend([] <unfinished ...> --- SIGRTMIN (Unknown signal 32) @ 0 (0) --- <... rt_sigsuspend resumed> ) = -1 EINTR (Interrupted system call) sigreturn() = ?
