# Replication testing utilities
# Environment handle for the env containing the replication "communications
# structure" (really a CDB environment).
# The test environment consists of a queue and a # directory (environment)
# per replication site. The queue is used to hold messages destined for a
# particular site and the directory will contain the environment for the
# site. So the environment looks like:
# $testdir
# ___________|______________________________
# / | \ \
# MSGQUEUEDIR MASTERDIR CLIENTDIR.0 ... CLIENTDIR.N-1
# | | ... |
# 1 2 .. N+1
#
# The master is site 1 in the MSGQUEUEDIR and clients 1-N map to message
# queues 2 - N+1.
#
# The globals repenv(1-N) contain the environment handles for the sites
# with a given id (i.e., repenv(1) is the master's environment.
# queuedbs is an array of DB handles, one per machine ID/machine ID pair,
# for the databases that contain messages from one machine to another.
# We omit the cases where the "from" and "to" machines are the same.

# To build a profiled version of BDB and tclsh and run the rep
# tests individually with profiling you need the following steps:
#
# 0. NOTE: References to 'X' below for BDB versions obviously need
# the current release version number used.
# 1. Need to build a static, profiled version of DB and install it.
# ../dist/configure with --disable-shared and --enable-static.
#
# NOTE: Assumes you already have --enable-debug configured.
#
# (if you use the script 'dbconf' the 'args' line looks like:)
# args="--disable-shared --enable-static --with-tcl=/usr/local/lib --enable-test $args"
#
# Edit build_unix/Makefile and add '-pg' to CFLAGS and LDFLAGS.
# make
# sudo make install
#
# 2. Need to make sure LD_LIBRARY_PATH in your .cshrc is pointing to the
# right path for the profiled DB, such as
# ... :./.libs:/usr/local/BerkeleyDB.5.X/lib: ...
#
# source your new .cshrc if necessary.
#
# [NOTE: Your Tcl version may vary. Use the paths and versions as a
# guide. Mostly it should be the same. These steps work for Tcl 5.8.]
# 3. Build a new, profiling tclsh:
# Go to your Tcl source directory, e.g. <..srcpath>/tcl8.5.8/unix
# make clean
# ./configure --disable-shared
#
# Edit the generated Makefile:
# Add '-L /usr/local/BerkeleyDB.5.X/lib' to tclsh target
# after ${TCLSH_OBJS}.
# Add '-ldb_tcl-5.X' to tclsh target before -ltcl8.5....
# Should look something like this:
# ${CC} ${LDFLAGS} ${TCLSH_OBJS} -L/usr/local/BerkeleyDB.5.0/lib -L/users/sue/src/tcl8.5.8/unix -ldb_tcl-5.0 -ltcl8.5 ${LIBS} \
# ${CC_SEARCH_FLAGS} -o tclsh
#
# May want to switch CFLAGS to CFLAGS_DEBUG.
# Add -pg to CFLAGS.
# Add -pthread to CFLAGS if it isn't already there.
# Need to add '-static -pg' to LDFLAGS.
# Change LDFLAGS to use $(LDFLAGS_DEBUG) instead of OPTIMIZE if needed.
# Change TCL_LIB_FILE to '.a' from '.so' if needed
#
# 4. Add Db_tcl_Init call to tclAppInit.c and an extern:
#====================
#*** tclAppInit.c.orig Mon Mar 17 12:15:42 2008
#--- tclAppInit.c Mon Mar 17 12:15:23 2008
#***************
#*** 30,35 ****
#--- 30,37 ----
#
# #endif /* TCL_TEST */
#
#+ extern int Db_tcl_Init _ANSI_ARGS_((Tcl_Interp *interp));
#+
# #ifdef TCL_XT_TEST
# extern void XtToolkitInitialize _ANSI_ARGS_((void));
# extern int Tclxttest_Init _ANSI_ARGS_((Tcl_Interp *interp));
#***************
#*** 145,150 ****
#--- 147,153 ----
# Procbodytest_SafeInit);
# #endif /* TCL_TEST */
#
#+ Db_tcl_Init(interp);
# /*
# * Call the init procedures for included packages. Each call should
# * look like this:
#
#====================
# 5. Build tclsh with 'make' but I do NOT suggest 'make install'.
#
# Test it has BDB built-in properly:
# Run ./tclsh in Tcl src (unix) directory:
# % berkdb version
# [Should show current BDB version.]
# % ^D
#
# Current directory should now have a tclsh.gmon or gmon.out file.
#
#
# 6. Edit build_unix/include.tcl to point to profiled tclsh and
# the static DB library:
#
# set tclsh_path <path to tclsrc>/tcl8.5.8/unix/tclsh
# set tcllib .libs/libdb_tcl-5.X.a
#
# 7. Comment out 'load $tcllib' in test/test.tcl
#
# 8. Run *your newly generated, profiled* tclsh as you normally would,
# including 'source ../test/test.tcl'
# build_unix% <path to tclsrc>/unix/tclsh
# % source ../test/test.tcl
#
# 9. Each test will be run in a separate tclsh and profiled individually.
# In the 'build_unix' directory you'll then find a <testname>.OUT file
# that contains the profile output. Run:
# % run_rep_gprof [start reptest name]
# This form runs all rep tests, starting with the given
# reptest name, or rep001 if no name is given.
# % run_gprof <testname>
# This form runs only the (required) specified test.
# NOTE: This form can be used on any individual test, not
# just replication tests. However, it uses 'run_test' so it
# must be a test that can be run through all the methods.
