BitKeeper/deleted/.del-client_func.c~3476a8a85cbd3c29: Delete: server-tools/instance-manager/client_func.c server-tools/instance-manager/Makefile.am: clien_func removed server-tools/instance-manager/buffer.cc: several methods added server-tools/instance-manager/buffer.h: Some error-handling fixes. server-tools/instance-manager/commands.cc: check for Buffer errors server-tools/instance-manager/guardian.cc: Guardian rewiriten. Not it works in a finite state machine-way. server-tools/instance-manager/guardian.h: Appropriate (to .cc) changes in the header + some comment added server-tools/instance-manager/instance.cc: added proxy thread to monitor instance. Two kinds of stop() now -- stop() and kill_instance which only sends a signal server-tools/instance-manager/instance.h: appropriate changes server-tools/instance-manager/instance_map.cc: cleanup server-tools/instance-manager/instance_map.h: cleanup server-tools/instance-manager/instance_options.cc: Caching of the pid-file-name is added. some comments added server-tools/instance-manager/instance_options.h: cleanup server-tools/instance-manager/listener.cc: listener my_thread_init added (though it doesn't use any mysys functions). Just in case server-tools/instance-manager/manager.cc: SIGCHLD handler removed. now instance monitoring is implemented through proxy threads. This is to work nicely with LinuxThreads server-tools/instance-manager/options.cc: added option to create a password file entry (this was implemented by Sergei Vojtovich) server-tools/instance-manager/parse.cc: inline function get_word moved to the header server-tools/instance-manager/parse.h: get_word moved here to use form parse_output server-tools/instance-manager/parse_output.cc: get_word() clone removed. now looking through the output linewise server-tools/instance-manager/protocol.cc: Buffer error chech added server-tools/instance-manager/user_map.cc: typo fixed
