#TODO:
|
|
#MEMLEAK fix
|
|
# see NodeRange.pm for notes about how to produce a memory leak
|
|
# xCAT as it stands at this moment shouldn't leak anymore due to what is
|
|
# described there, but that only hides from the real problem and the leak will
|
|
# likely crop up if future architecture changes happen
|
|
# in summary, a created Table object without benefit of db worker thread
|
|
# to abstract its existance will consume a few kilobytes of memory
|
|
# that never gets reused
|
|
# just enough notes to remind me of the design that I think would allow for
|
|
# -cache to persist so long as '_build_cache' calls concurrently stack (for NodeRange interpretation mainly) (done)
|
|
# -Allow plugins to define a staleness threshold for getNodesAttribs freshness (complicated enough to postpone...)
|
|
# so that actions requested by disparate managed nodes may aggregate in SQL calls
|
|
# reference count managed cache lifetime, if clear_cache is called, and build_chache has been called twice, decrement the counter
|
|
# if called again, decrement again and clear cache
|
|
# for getNodesAttribs, we can put a parameter to request allowable staleneess
|
|
# if the cachestamp is too old, build_cache is called
|
|
# in this mode, 'use_cache' is temporarily set to 1, regardless of
|
|
# potential other consumers (notably, NodeRange)
|
|
#perl errors/and warnings are not currently wrapped.
|
|
# This probably will be cleaned
|
|
#up
|
|
#Some known weird behaviors
|
|
#creating new sqlite db files when only requested to read non-existant table, easy to fix,
|
|
#class xcattable
|
|
#FYI on emulated AutoCommit:
|
|
#SQLite specific behavior has Table layer implementing AutoCommit. There
|
|
#is a significant limitation, 'rollback' may not roll all the way back
|
|
#if an intermediate transaction occured on the same table
|
|
#TODO: short term, have tabutils implement it's own rollback (the only consumer)
|
|
#TODO: longer term, either figure out a way to properly implement it or
|
|
# document it as a limitation for SQLite configurations

xCAT::Table - Perl module for xCAT configuration access
|
|
|
|
=head2 SYNOPSIS
|
|
|
|
use xCAT::Table;
|
|
my $table = xCAT::Table->new("tablename");
|
|
|
|
my $hashref=$table->getNodeAttribs("nodename","columname1","columname2");
|
|
printf $hashref->{columname1};
|
|
|
|
|
|
=head2 DESCRIPTION
|
|
|
|
This module provides convenience methods that abstract the backend specific configuration to a common API.
|
|
|
|
Currently implements the preferred SQLite backend, as well as a CSV backend, postgresql and MySQL, using their respective perl DBD modules.
|
|
|
|
NOTES
|
|
|
|
The CSV backend is really slow at scale. Room for optimization is likely, but in general DBD::CSV is slow, relative to xCAT 1.2.x.
|
|
The SQLite backend, on the other hand, is significantly faster on reads than the xCAT 1.2.x way, so it is recommended.
|
|
|
|
BUGS
|
|
|
|
This module is not thread-safe, due to underlying DBD thread issues. Specifically in testing, SQLite DBD leaks scalars if a thread
|
|
where a Table object exists spawns a child and that child exits. The recommended workaround for now is to spawn a thread to contain
|
|
all Table objects if you intend to spawn threads from your main thread. As long as no thread in which the new method is called spawns
|
|
child threads, it seems to work fine.

=head3 setAttribsWhere
|
|
|
|
Description:
|
|
This function sets the attributes for the rows selected by the where clause.
|
|
Warning, because we support mulitiple databases (SQLite,MySQL and DB2) that
|
|
require different syntax. Any code using this routine, must call the
|
|
Utils->getDBName routine and code the where clause that is appropriate for
|
|
each supported database.
|
|
|
|
Arguments:
|
|
Where clause.
|
|
Note: if the Where clause contains any reserved keywords like
|
|
keys from the site table, then you will have to code them in backticks
|
|
for MySQL and not in backticks for Postgresql.
|
|
Hash reference of column-value pairs to set
|
|
Returns:
|
|
None

Example:
|
|
my $tab = xCAT::Table->new( 'ppc', -create=>1, -autocommit=>1 );

each supported database.
