[ome-devel] OME install woes: upload file through omeis

[Ilya Goldberg]

The XML files imported during installation establish OME's semantics  
(i.e. its loading all of its data models), which may or may not  
result in the creation of DB tables to accommodate them (the first  
install will always create tables).

Because OME insists on knowing the origin of all things, this poses a  
significant chicken-egg problem during installation, so I don't think  
the bootstrapping phase can be done manually.  All the XML after the  
bootstrap could in principle be installed manually.  It would have to  
be done in the proper order though, or everything would have to be  
dumped into a single huge XML file.

Your error occurred in the bootstrap phase, but on the third file,  
having successfully uploaded the first two. Did you see it report the  
successful completion of the first two files (InstallationModule.ome  
and Experimenter.ome)?
This is very strange.  As though /home/swaroop/OME/src/xml/OME/Core/ 
OMEIS/Repository.ome really was corrupt or something.  Or the  
transfer was interrupted for some other reason.  "500 EOF when chunk  
header expected" is not an error generated by OME - it originates  
from one of the HTTP protocol handlers, which makes me think this is  
a pretty low-level problem.  The local XML files are transfered to  
OMEIS using the HTTP protocol.  This is the case even when everything  
is local.

Can you try again from a fresh CVS checkout?


Regarding re-thinking the installation process, one way to rethink it  
is how this is managed by the OS X installer (which is GUI-based).   
Essentially, the GUI fills out the install environment object, which  
can be edited and processed in a text version (see examples in /doc/ 
install-configs/).  Once this is all filled out and all the Perl and  
C dependencies are installed and Apache, mod_perl, and Postgres are  
all checked and rechecked, the OME installer is launched in non- 
interactive mode (install.pl -y -f envFile).
