Another Aiieee.....
by Jon Prettyman 03 Nov '00

03 Nov '00

I am once again encountering the mysterious Aiieee error with core dumps from Zope/Python on a Solaris boxen. SunOS sparky 5.7 Generic_106541-08 sun4m sparc SUNW,SPARCstation-20 Python 1.5.2 (#1, Oct 24 2000, 11:56:43) [GCC 2.8.1] on sunos5 Zope-2.2.2 DCOracle 1.3.2 448M ram I get the following in my STUPID_LOG 2000-11-03T20:42:10 ERROR(200) zdaemon zdaemon: Fri Nov 3 14:42:10 2000: Aiieee! 17537 exited with error code: 139 /usr/include/sys/errno.h looks like this: #define ECONNABORTED 130 /* Software caused connection abort */ #define ECONNRESET 131 /* Connection reset by peer */ #define ENOBUFS 132 /* No buffer space available */ #define EISCONN 133 /* Socket is already connected */ #define ENOTCONN 134 /* Socket is not connected */ /* XENIX has 135 - 142 */ #define ESHUTDOWN 143 /* Can't send after socket shutdown */ #define ETOOMANYREFS 144 /* Too many references: can't splice */ #define ETIMEDOUT 145 /* Connection timed out */ #define ECONNREFUSED 146 /* Connection refused */ #define EHOSTDOWN 147 /* Host is down */ #define EHOSTUNREACH 148 /* No route to host */ What is a 139 error code? Is it an errno? I do get core dumps but for some reason I can't get gdb to read it. Arghhh. Crashes appear random. The box has at most two people accessing Zope. It appears ``manage'' related, but I can't be sure. There is an identical instance of this Zope application running on a Linux box that does not have this problem. It is very stable. We'd like to use this Solaris boxen for our development work. -jon

Help with general purpose ZSQL Method
by Jon Prettyman 03 Nov '00

03 Nov '00

I want to write a generic table browser ZSQL method and am having trouble getting the output that I want. Given a ZSQLMethod that looks like this: ID: browse_table Arguments: table:string="" Script: SELECT * FROM <dtml-var table> I'm trying to write a DTML method to display the results of this method WITH COLUMN NAMES. For the life of me, I can't figure out how to do this. Basically, I have: <dtml-in "browse_table(table='xxxx')" size=1> <dtml-in sequence-item> <dtml-var sequence-item> </dtml-in> </dtml-in> The inner sequence-item gives me the data, but how to I determine the column name? -jon

Zopistas, I would like to make a Zclass a baseclass of the Btree folder object. I installed Btree but it's not appearing in the list of base classes. Is there a way to get it in there? Any help would be greatly appreciated. Thanks in advance, -Darin Lee

Obtaining just the filename for multiple file fields in an add form form
by Darin Lee 03 Nov '00

03 Nov '00

Zopistas, I have a form that has multiple file upload fields in it (5 to be exact). I am handling the upload via DTML. Essentially this is a "publication" item that can have multiple formats of a file attached (PDF, Powerpoint, Word, Excel, HTML). I would like the user to create the publication item (Zclass object), and then attach whatever format files they require to the add form. The Publication object is folderish and contains which of the files they uploaded. The problem comes in with naming the files. I can't figure a way to get the file name from the upload field without getting the entire local path on the user's machine. The following code works, if I manually delete the path out of the field in the browser (ie5) and just leave the filename: <dtml-call "manage_addFile(_.getattr(file1, 'filename'), REQUEST['file1'])"> However, I would rather get the filename, split it on the \'s, and then take a slice to get at the actual filename [:1] to pass to manage_addFile. The problem is, I'm not sure how to get this to work in DTML. This is also clumsy, because in this case there are 5 file upload fields on the form - the way I am approaching it would require the same code to be repeated 5 different times. Is there an array/list of the file fields I could loop through? Thanks in advance, -Darin Lee

pluggable brains
by Philipp Auersperg 03 Nov '00

03 Nov '00

For ZSQL Methods it is possible to bind a ZClass to the records. These can be selected from te combo box labeled 'ZClass' in the 'advanced' tab of the SQLMethod's management screen, but there is always listed just one ZClass. My question: Why is there just one ZClass selectable, even if there are many ZClasses defined? Is that a bug or a feature? thanks phil
