RE: Can't make the Sybase DA
by Bauer, Georg 03 Apr '00

03 Apr '00

Hi! Attached a mailing with the support-list at digital creations. Looks like they have no idea what's happening. Any one around here any idea? Recap on the situation: it looks like there is a circular dependency in the Sybase-DA Makefile.pre.in: Makefile.pre.in creates Makefile.pre, but that needs sedfile and that needs Makefile which is the goal of the whole process and therefore can't exist at this moment. Python-dev and Sybase dev-libs are installed (FreeTDS for the Sybase dev-libs, but I have the original libs, too). bye, Georg > -----Original Message----- > From: Chris McDonough [SMTP:chrism@digicool.com] > Sent: Friday, March 31, 2000 6:50 PM > To: Georg Bauer > Cc: support(a)digicool.com > Subject: Re: Can't make the Sybase DA > > Georg, > > You're probably missing your Sybase and/or Python development libraries > on the machine you're trying to build this on.

Let's sum up: the Anonymous role is revoked all rights from the top level, and a role 'User' is created with the same rights as Anonymous. In the toplevel, a user 'u' is given the role 'User'. In a sub folder, another user folder is created, and 'u' is given the roles 'Manager' and 'User'. When 'u' try to browse the subfolder, an exception is raised because he is unthorized to access standard_html_header (???) Note that if standard_html_header is copied in the subfolder, the error goes away. This is very bizarre. Should I post this to the collector? > I should mention that I revoked all rights for anonymous users. > So everybody must log in to use the site. I think that all "public" content must be viewable by the anonymous user, even if it desirable that all users have to authenticate (ie, the "public" is well known) the problem is that authentication is not required for anonymous content. I just written a product, jcForceAuth, which force users to authenticate, even for anonymous content. you can see it at http://www.zope.org/Members/jephte/jcForceAuth This is a product, and it is installed the usual way. It "patches" ZPublisher on the fly to raise unauthorized if no authentication headers are found. I hope this helps BTW, any comments are welcome regards, jephte clain minf7(a)educ.univ-reunion.fr

oracle connection issue
by Ken Kinder 03 Apr '00

03 Apr '00

Something is wrong with the way I'm connecting. When my server rebooted unelegantly (some idiot unplugged it), I restarted both Zope and Oracle. I restaretd Oracle using dbstart and turned on its listeners. on the server, locally, sqlplus works fine. From Zope, however, I get the oracle error "ORACLE initialization or shutdown in progress" (ora 01033) which is clearly not the case, as local sqlplus seems to work fine. Any ideas? -- Ken Kinder 303.381.7631

Um, what about ( untested, but it should work) <dtml-call "manage_delProperties([ids, REQUEST])">, in which ids refer to the properties. On a specific object that would be: <dtml-with <yourobject>> <dtml-call "manage_delProperties([ids, REQUEST])"> </dtml-with> or <dtml-call "<yourobject>.manage_delProperties([ids, REQUEST])"> Note, however, that the ids argument is a list. SO put the ids between square brackets, like <dtml-call "<yourobject>.manage_delProperties([id1,id2,id3], REQUEST])"> A form calling the method should also provide a list argument for ids. If you want to do something of the sort, I suggest you adapt the manage_propertiesForm from Zope to your needs. Calling from a URL (for example from a href in a dtml document) is also possible.

referring to previous directories using references? (../, ./, etc)
by Kevin Howe 02 Apr '00

02 Apr '00

How do you refer to previous directories in ZOPE? On a filesystem you would use references: Current Directory ./ Previous Directory ../ but these don't seem to work with ZOPE. I have a structure like this: ZClass1 | --- Folder | --- ZClass2 | --- DTML Method or Document Sometime ZClass2 is inside ZClass1, and sometimes it's on it's own. I'd like to be able to say: # check if the object two levels up is a ZClass1 instance   # do this   Anyone know how I can go about this? kh

MySQLDA and MySQLdb probs and solns
by Eric L. Walstad 02 Apr '00

02 Apr '00

When building MySQLdb: "ImportError: No module named _mysql" This little error message plagued me for about 3 weeks. After reformatting my hard drive and re-installing Linux, Python, MySQL and MySQLdb, all from the source files, I finally found the solution (well, it worked for me) and am posting it for anyone else that runs into the same trouble. The good news (for you) is that all the re-installing isn't necessary. Note that this solution is for a problem I had in following the "How-To ZMySQLDA - from download to connection" step number four. ### SOLUTION (worked for me)### In order to fix the "ImportError: No module named _mysql" error: Ensure that there exists the /usr/lib/mysql folder containing the following files: libdbug.a libmysqlclient.a libmysqlclient.so.6 libmysys.a libheap.a libmysqlclient.la libmysqlclient.so.6.0.0 libnisam.a libmerge.a libmysqlclient.so libmystrings.a <Problem #1> I had to copy /user/local/lib/mysql to /usr/lib/mysql </Problem #1> To fix the "ImportError: libmysqlclient.so.6: cannot open shared object file: No such file or directory" error: Ensure that there exists the libmysqlclient.so.6 file in the /usr/lib folder. <Problem #2> The libmysqlclient.so.6 file was missing from the /usr/lib folder. I tried putting a link to the libmysqlclient.so.6 file in the /usr/lib folder and it didn't work. Next, I copied the libmysqlclient.so.6.0.0 file to the /usr/lib folder, renamed it to libmysqlclient.so.6 and that was enought to make the build.py script run all the way through. </Problem #2> To successfully complete the installation, I did the following: [root@frankenstein MySQLdb]# make install [root@frankenstein MySQLdb]# cp MySQLdb.py{,c,o} /usr/local/lib/python1.5/site-packages [root@frankenstein MySQLdb]# cp ZMySQLDA.patch /usr/local/Zope [root@frankenstein MySQLdb]# cd /usr/local/Zope [root@frankenstein Zope]# patch -p1<ZMySQLDA.patch patching file `lib/python/Products/ZMySQLDA/DA.py' patching file `lib/python/Products/ZMySQLDA/db.py' Hunk #1 succeeded at 103 with fuzz 2. ### Explanation (what I learned) ### First, here's the full error message: gcc -fpic -I/usr/include/mysql -g -O2 -I/usr/local/include/python1.5 -I/usr /local/include/python1.5 -DHAVE_CONFIG_H -c ./_mysqlmodule.c gcc -shared _mysqlmodule.o -L/usr/lib/mysql -lmysqlclient -o _mysqlmodule.so /usr/i386-linux/bin/ld: cannot open -lmysqlclient: No such file or directory make: *** [_mysqlmodule.so] Error 1 Traceback (innermost last): File "build.py", line 14, in ? import MySQLdb File "MySQLdb.py", line 19, in ? from _mysql import * ImportError: No module named _mysql I needed to understand what was happening, so here is what I learned in breaking this error message down: <First Command> gcc -fpic -I/usr/include/mysql -g -O2 -I/usr/local/include/python1.5 -I/usr /local/include/python1.5 -DHAVE_CONFIG_H -c ./_mysqlmodule.c This command is creating an object file (it will be called "_mysqlmodule.o" by default) from the "_mysqlmodule.c" file. -fpic = tells the compiler to created a shared library -fPIC = tells the compiler to create a dynamically linked shard library (not used here, but good to know) -c = Tells the compiler to compile only - doesn't create an executable -g = compile code for debugging (I don't know why we are putting the debug info in it.) -O2 = Tells the compiler to use the second level of optimization -I<path> = Defines path to the header files that are '#include'd in the C programming code files. </First Command> <Second Command> gcc -shared _mysqlmodule.o -L/usr/lib/mysql -lmysqlclient -o _mysqlmodule.so This command creates a shared library out of _mysqlmodule.o, called _mysqlmodule.so, and links it to /usr/lib/mysql/libmysqlclient.so" -shared = Tells the compiler to place the compiled files into a library -o<name> = tells the linker to build the '<name>' library -L<path> = adds <path> to the list of paths to search when looking for the library to be linked -l<name> = Name of the library to link to. Tells the linker to link the -o<name> program to the 'lib<name>.so' library file </Second Command> <First Error> /usr/i386-linux/bin/ld: cannot open -lmysqlclient: No such file or directory This error happened because the linker (the ld program) searched for the "libmysqlclient.so" file and couldn't find it. </First Error> <Second Error> make: *** [_mysqlmodule.so] Error 1 Traceback (innermost last): File "build.py", line 14, in ? import MySQLdb File "MySQLdb.py", line 19, in ? from _mysql import * ImportError: No module named _mysql This error happened because the first error caused a failure to create the "_mysqlmodule.so" file. The "_mysqlmodule.so" library file contains a module called _mysql. Because the library file wasn't there, neither was the _mysql module. </Second Error> Next I tried to run the build.py script and received the following error: <Third Error> Traceback (innermost last): File "build.py", line 14, in ? import MySQLdb File "MySQLdb.py", line 19, in ? from _mysql import * ImportError: libmysqlclient.so.6: cannot open shared object file: No such file or directory This error happened because the "from _mysql import *" statement caused the "_mysqlmodule.so" library to be loaded, which caused the "libmysqlclient.so.6" to be loaded, also. Remember that the command: "gcc -shared _mysqlmodule.o -L/usr/lib/mysql -lmysqlclient -o _mysqlmodule.so" (the Second Command, above) linked the "libmysqlclient.so.6" library to the "_mysqlmodule.so" that's why they are both being loaded. </Third Error> I realize that this problem was likely caused by a missing, or incorrect, path statement somewhere in my system. My solution of simply copying files around is not very elegant, but it worked. A better solution would've been to fix the paths. I don't know how to do that, but when I figure that out, I'll come back and fix it. Any comments on this solution are welcomed! Eric.

Zope & Frames
by Eron Lloyd 02 Apr '00

02 Apr '00

Is there a DTML way to programatically insert documents into the different frames of a frameset? Say I had a three paned frameset (header, menu, content) and I wanted documents in the content frame to be able to open up to the full browser window (i.e. <a href="<dtml-var id>" target="_parent">fullscreen</a>). I would also like to have a link in each document that would put the document BACK in it's previous frame. Is there a magical way this can be done? Or am I missing something VERY obvious? Much appreciated, Eron
