    - Back off on a project if we make a scheduler RPC asking for work
        and don't get any
    - fixed "http_proxy_name" XML parsing problem in client
    - added drand() function.
        NOTE: always make repeated code blocks into functions
    - make_work was using uninitialized seqno, caused negative
        numbers in filenames

David  Jan 3 2003
    - added some indices to DB.

    NOTE: there must be an index for each field or combination of fields
        that we do a "select" on!!

David  Jan 6 2003
    - change all server programs to do logging the same way:
        - all log entries written to stderr
        - write date/time at start of log entries
        - don't include program or user name in log entries
    - client: when get no work from project,
        don't back off if we're in exit_when_idle mode
    - added ob_end_flush() call in test.inc so that PHP test scripts
        have unbuffered output
    - added other backend phases (validate, file_delete) to test_loop.php
    - PROGRAMMER NOTES:
        - don't use tab chars in files
        - split long comments into separate lines
        - "extern" should never appear in a .C file
        - Don't use member function names that conflict with global functions
            (e.g. CLIENT_STATE::exit(); use cleanup_and_exit() instead)

    - extend client "print state summary" function to give more
        detailed information about state, e.g. names and states
        of everything, and active file xfers and tasks
    - fixed bug where feeder inserted same result twice in shmem

David  Jan 8 2003
    - changed the DB code so that you can use the mySQL utility functions
        to access different databases from a single program.
        There's now a MYSQL_DB class that you can subclass.
        See db_mysql.C for an example.

    - With -no_time_test flag, client now uses default values for
        various speeds, rather than zero
    - Restored commented-out timezone code.
        May need to get working on Solaris
    - Added stripchart scripts for getting DB info
        (need to macro-substitute DB name)

    Net result: test_loop.php now works correctly and generates
    stripcharts that show an ever-growing set of results

    - Changed some of the state fields of workunit and result,
        to accommodate new policies about when to delete files
        See doc/backend_* for details
    - Split off dummy assimilation function from the main program.
    - Added new stripchart scripts for logging DB counts
        and directory sizes

    NOTE: it looks like shared memory segment is at same address
    in feeder and cgi.  So it's OK to use pointers in it.

        Rendering logic is now entirely in the GUI thread.
        It's up to the application to synchronize computation and rendering.
    - added REDUCED_ARRAY::draw_part()

David  Feb 12 2003
    - Added mechanism for starting or restarting all back-end processes
        for a project.  A list of the programs are now in config.xml.
        All programs now use lock files to prevent duplicate execution.
        A new program "start_servers" reads config.xml and starts servers.
    - Added "user-friendly name" field to platform, so that users
        see e.g. "Windows 95/98/XP" instead of "windows_intelx86"
        NOTE: this requires patching existing databases

    - changed "exit_after" to "exit_after_app_started_secs"
        and changed its null value from -1 to 0.
    - don't ask a scheduler for work if in exit_when_idle mode
        and we've already contacted scheduler

        (intro, banner, etc.) is in a separate file.
        Can specify this file in test scripts.
    - added test scripts to make dummy SETI@home and Astropulse projects,

David  Feb 18 2003
    - added "opaque" fields to result and workunit tables.
        (allows projects to cross-reference to their science DB)
    - added "venue" field to host (home/school/work)
        This has two goals:
        1) provides a basis for multiple preference sets
            (one each for home/school/work)
        2) provides another account breakdown for stats
    - added "venue" field to user
        This is the default venue, for newly created hosts
    - simplified preferences:
        For account setup, all preferences are now on one form
        (different forms for new/return users)
        For preference editing, preferences are now in two groups
            - project preferences, including resource share,
                venue, and per-project prefs
            - global prefs (called "BOINC prefs" in user interface)
    - fixed bug where user/host credits in client state file were giant numbers

David  Feb 19 2003
    - Added scheme for verified user update of email address
        When user updates email address, their email address in the DB
        is set to a "munged" form that includes a random string,
        and an email is sent to the new address that includes a
        URL that they must visit to verify the change.
    - The same mechanism is used on account creation;
        the email DB field is initially set to a munged form.
        This prevents hackers from adding entries to the DB
        with other peoples' email addresses.
    - Separate logic for update email address from update other user info;
        remove combinatorial logic (?) for update other user info

    - changed windows graphics handling.
        client now has a child window in which all graphics are displayed.
        when an app is running, this window sends a message to the app telling
        it to draw on the window.

    - Implemented network throughput limits, part of global prefs.
        There are separate limits for upload and download.
        Implementation: the NET_XFER_SET objects now has fields for
        1) the max # bytes/sec up and down (from global prefs)
        2) the limit on bytes that can be xferred this second
            Can go negative.  If it's negative, don't include
            sockets in select().
            Replenish every second.
        This replaces an implementation that didn't work
    - Reimplemented the way network throughput is measured.
        The old way measured throughput for each file xfer, and kept an average.
        This doesn't work with multiple simultaneous xfers.
        The new way uses a NET_STATS::poll() function.
        If there has been an active file xfer during the last poll period
        (new logic in NET_XFER_SET lets you find this out)
        then you add the duration of the polling period,
        and the number of bytes transferred.
        The reported throughput is averaged with throughput
        from previous sessions of the core client.
    - Increased file xfer blocksize from 4KB to 16KB
    - Got rid of dynamic buffer allocation in NET_XFER
    - Renamed "water days" to "work buf days" everywhere
    NOTE:
        clock() measure calling process CPU time, not time of day.
        Use time(0) if you want time of day.

    - Added net transfer progress.  Tracks number of bytes transferred
       for file uploads and downloads.
    - Fixed Windows battery status bug.
    - Net transfer speed measurement in bytes/sec. The measurement decays by
       1/2 every 3 seconds.
    - Added PHP function to password protect project admin pages via .htaccess.
    - Altered show_message function to specify the project a message is
       associated with.

    - use trim() to get rid of white space and start/end of authenticator.
        Should do this for most user-supplied data
    - use row2() to generate all two-item rows.
        Right-align the first part and embolden the second.
        Get rid of row() and row2a()

        zero disk or zero memory;
        improved reporting of infeasibility
    - added a "watchdog" script (wd.php) that checks log files for error msgs

    - added PHP code for creating/editing/deleting multiple pref sets
        See "prefs.inc" for a description of the XML format.
        Prefs are divided into two subsets (global and project).
        For each subset there is a mandatory "primary" version
        and optional versions for home, school, and work.
        The prefs display/editing code has been consolidated
        and parameterized (subset = global or project,
        venue = none, home, school, work).
        This actually simplifies things a little.

    - use venue-specific prefs on client side:
        - schedule server passes <host_venue> element in scheduler reply
            (but only when it passes back new global prefs)
        - when parsing global prefs, if find a matching
            <venue> element, parse its contents and ignore all else
        - when passing project-specific prefs to app,
            look for matching <venue> element
    - changed XML syntax of venue-specific prefs: instead of
        <home>...</home>, e.g., use
        <venue name="home">...</venue>
    - added safe_strncpy(): always adds zero byte at end.
        Use this instead of strncpy().

    - messages are now timestamped and show project name
    - use start_table() and row2() more uniformly in user HTML
    - user HTML: show message if can't connect to DB
    - standardize terminology in user HTML: "general prefs",
        "default computer location", etc.

        - changed windows graphics handling again.  client/app messaging
                now mainly consists of the client polling the app windows,
                with apps messaging the client when they change modes.
                moved most of this into the client's child screensaver window.

    - Changed app->client communication to use shared memory rather
      than files.  The client sets up a shared memory segment when
      starting the app. The app attaches to it and writes XML tags
      into a 4K text buffer every second.
    - The shared memory communication has been tested by hand under
      Windows and UNIX (Mac OS X).  We should write test scripts for
      it to make sure.

Erik  May 6 2003
    - Added a notion of "transient" and "permanent" errors on file uploads.
        A permanent error is returned by the file upload handler if
            - the request is malformed
            - filename includes ".."
            - the signature is bad
            - the file size is larger than allowed
        PERS_FILE_XFER checks for this return from FILE_XFER
        and gives up immediately.
    - FILE_XFER now always parses the server response (not just for file size)
    - Added some missing error checks to FILE_XFER
    - Punted on the timezone-related ifdefs:

    - Added a new class SS_LOGIC that encapsulates the core client's
        screensaver-related logic.
        It tries to get graphics-capable apps to provide graphics,
        and if necessary it draws logo-based graphics or blanks the screen.
    - Changed ACTIVE_TASK.app_client_shm from a pointer to an object.
        NOTE: AVOID DYNAMIC ALLOCATION WHENEVER POSSIBLE

Erik  May 13 2003
    - Added a notion of "tentative" project.
        This means that the (URL, account ID) pair hasn't been verified,
        i.e. we haven't fetched the master page, found a scheduler,
        and done a scheduler op that verified the account ID.
        If anything fails for a tentative project, call project_add_failed().
        in the cmdline version this prints an error message,
        deletes all evidence of the project, and exits.
        TODO: implement for GUI
    - Make write_account_file() into a member function of PROJECT.
    - Got rid of CLIENT_STATE::change_project().
        The user must detach and attach.
    - CLIENT_STATE::quit_project() now takes a PROJECT*, not an int.
        Need to change the GUI code.
    - got rid of separate WIN_32 implementations of
        make_project_dir(), remove_project_dir(), make_slot_dir().
        THIS IS THE WRONG LEVEL FOR PLATFORM-DEPENDENT CODE!
        Instead, added boinc_mkdir() and boinc_rmdir()
    - added implementation docs for screensaver logic
    - test_uc.php: wait for a second before running client.
        On fast computers the client runs before feeder has seeded shmem.

        net_xfer.C

Erik  May 16 2003
    - set FILE_INFO::upload_offset to -1 before restarting file upload.
        This forces file size check, so that upload can resume
        with nonzero offset.
        NOTE: THE USE OF "SPECIAL VALUES" (LIKE -1) IS DISCOURAGED
    - don't set RESULT::state to NEW after parse.
        This caused completed results to start over.
    - PERS_FILE_XFER::start_xfer() is int, not bool
    - better messages on file transfer failure and project backoff
    - better message from scheduler if wrong major version
    - file upload handler logging is on by default

Erik  May 19 2003
    - added support for user-selected files to be included
        as part of an app_version.
        If there is an element of the form
            <app_file>
                <url>X</url>
                <open_name>Y</open_name>
            </app_file>
        in a user's project preferences,
        then for every APP_VERSION that is sent to the user,
        elements of the form
            <file_info>
                <name>X'</name>
                <url>X</url>
            </file_info>
            ... and in the <app_version> element
            <file_ref>
                <file_name>X'</file_name>
                <open_name>Y</open_name>
            </file_ref>
        are added to the app version's XML description,
        where X' is an escaped version of X.
        This can be used (for example) to allow applications to
        have user-specified images in their graphics
    - Handle it correctly if the "insert" part of a file transfer fails
    - The "main program" of an app version is the one labeled <main_program/>
        (not necessarily the first one)
    - Only files labeled <executable/> are required to be signed
    - added copyright notice to some files
    - added sgets() for parsing a string that is made up of multiple lines
    - write MD5 checksum elements only if checksum is present
    - created escape_url_readable

    TODO: app_versions are currently treated as immutable by client.
        Need to change this.

    - various changes to support abort of apps if use too much disk or CPU
        - send workunit rsc_* fields in scheduler reply; store on client
        - scheduler doesn't send estimated CPU time; instead,
            client calculates it
        - CPU time bound is estimated time * 2
        - disk bound is rsc_disk
        TODO: finish implementing this
    - When an app finishes, see if any of the output files is larger
        than its max_nbytes.
        If so set its status to ERR_FILE_TOO_BIG.
        This will prevent the client from trying to upload it.

    - abort applications that exceed max disk usage
        Do this check at most global_prefs.disk_interval seconds
    - moved code that detaches core/app shared memory from
        CLIENT_STATE::handle_finished_apps() to
        ACTIVE_TASK::check_app_exited()
        NOTE: ACTIVE_TASK IS SUPPOSED TO ENCAPSULATE TASK IMPLEMENTATION
    - CLIENT_STATE::handle_finished_apps(): don't view an app as finished
        if it's in PROCESS_ABORT_PENDING state
    - got rid of ACTIVE_TASK_SET::poll_time();
        moved its functionality to ACTIVE_TASK_SET::poll()
    - broke up ACTIVE_TASK_SET::poll() into subfunctions:
        get_cpu_times(), check_app_exited(),
        check_max_cpu_exceeded(), check_max_disk_exceeded()
    - change function names:

        check_app_state() -> get_cpu_time_via_shmem()
        handle_running_aps() -> handle_finished_apps()

    - If connect() fails, mark the HTTP_OP as done and in error.
        Previously it just hung forever.
    - Added DB fields for BOINC disk usage: total, project, and max
        TODO: compute these on client and send in sched RPC
    - Scheduler RPC request now includes a list of projects
        and resource shares for the host.
        Stored in the DB.
        This lets the web site show other projects
        that people participate in.
        Also might be used in scheduling estimates.
    - added a "Rules and policies" page to the web interface.
        Users read this before creating account
    - commented out check_max_mem_exceeded() (not ready)

    - Make sure the user can't add one project twice (by one having a trailing

        Canonicalize master urls to have a trailing '/' and remove double
        slashes.  Ensure account filenames and directories do not have the
        trailing '_'.  For many users their account files already have
        trailing '_'s so if such files are found, rename them and their
        corresponding project directories on startup.  Created C++ string
        versions of some functions for easier/safer/more efficient string

        a separate function suspend_activities() does the suspending
    - don't start new FILE_XFERS while suspended

    - changed DB interface to make it possible for an application
        to use different MySQL databases at the same time.
        A new class DB_CONN represents a connection to a database.
        Old functions like boinc_db_open() etc. are members of this class.
        The connection to the BOINC database is represented by
        by a global object "boinc_db" of this class.
        You're free to have others
        (e.g. "app_db" in the work gen or assimilator for an app)

            - new count() methods with arbitrary arguments like find()
        - misc. bug fixes

    - transitioner: set file delete state to READY only if it's currently INIT
        This should make file_deleter more efficient,
        because each WU/result is file-deleted only once.
        Also means that unlink()s should always succeed
    - file deleter: print retval of unlink() (should always be zero)

David  Sept 21 2003
    - Added mechanism for marking results as COULDNT_SEND:
        When the scheduler finds that a result is infeasible
        for a host, it increments the "infeasible_count" in the work array.
        When the feeder finds that too many results in the array
        have nonzero infeasible_count, it marks some of them
        as COULDNT_SEND and removes them from the array

        boinc_db.h
    sched/
        feeder.C
        handle_request.C
        sched_shmem.h

David  Sept 21 2003
    - Partly debugged the above changes:
    - The feeder's result enumeration should have no limit;
        otherwise it may enumerate the same results over and over
    - If the infeasible_count of a result a threshold (MAX_INFEASIBLE_COUNT)
        the feeder marks it as couldnt_send.
        This prevents a situation where results sit in the work array
        forever, their infeasible_count approaching infinity
    - Added show_shmem to sched/ Makefile, and fleshed it out a bit
    - Show hostID correctly when get RPC from wrong major version

    NOTE: still haven't exercised the case where a result is marked COULDNT_SEND

    Modified DB_CONN::open() to support "db_name@host" syntax for remote
    database connections.

David  Sept 23 2003
    - Don't reference-count WUs for results that are ready to report
        (since don't need their input files anymore)
        NOTE: this means that RESULT.wup may be zero.
        Much check before dereferencing.
    - Changed "ready_to_ack" to "ready_to_report"
        (Ack is server->client, not client->server)
    - Changed "server_ack" to "got_server_ack"
    - Moved CLIENT_STATE integrity-check code to a new file (check_state.C)
        In general it would be nice to move stuff out of client_state.C;

    - Create an XML entity encoder/decoder for single byte entities.  In new
      files lib/xml_util.[Ch].  Encoder will make the following translations.
        '>' => "&gt;"
        '<' => "&lt;"
        '&' => "&amp;"
        "'" => "&apos;"
        '"' => "&quot;"
        other unprintable -> "&#nnnd;"
      The decoder recognizes a larger number of translations for single byte
      entities found in XML/HTML.

          platform, app, app_version, or core_version.  Use `add' for these.
        - database actions are through MySQLdb, removing need for mysql client

        to represent an OpenGL texture (including its ID and size).
    - Modify draw_texture() to not change the aspect ratio of the picture;
        it shrinks the image in one dimension or the other, and centers
        it in the allotted space
    - Add a GRAPH_DRAW_STYLE field to REDUCED_ARRAY

    - Don't send two results from the same WU in a single RPC
        Note: this is a weak but possibly sufficient step towards not sending
        multiple results from the same WU to one user.
    - Scheduler: before updating a result, reread it from the database.
        What's in shared memory may be way out of date.
        E.g. it may no longer be in server state UNSENT.

    - Added debugging printfs (enabled by #define DEBUG)
        to wingui_mainwindow.cpp.  These write to C:/temp/core.txt.
    - In CMyApp::InitInstance(), changed 2nd arg of CreateMutex
        from false to true.  This matches "1 instance" code samples from web.
        Thought it might fix startup bug - no.
    - Added debugging printfs (enabled by #define DEBUG) into screensaver;
        causes it to write info to C:/temp/boinc_scr.txt
    - Removed CREATE_NO_WINDOW and IDLE_PRIORITY flags from
        CreateProcess() call in screensaver.
        These aren't listed in the MSDN man page; are they needed?
    - slight change to startup logic in screensaver:
        - send it a BOINC_SS_START message only if it's already running
            (not needed if start it ourselves, since we give it -saver arg)
        - don't wait for 3 seconds after starting it
    - In the cmdline passed to the core client from screensaver,
        make argv[0] the real path of the executable.
        Thought this might fix startup bug - no.
    - Change "start_saver" to "started_by_screensaver".  Truth in advertising.

    - moved OpenGL init calls from the start of the event loop
        back to SetMode, undoing an earlier change.
        Turns out the need to be in SetMode because it creates a new
        window every time.

    - Parse project-specific prefs correctly (i.e. based on venue)
        These prefs are read from account files.
        Account files are read before the client state file is parsed.
        This presented a problem because the host venue,
        which is needed to decide which project prefs to use,
        is kept in the client state file.
        So I added a new function, parse_venue(), that gets the
        host venue from the state file; this is done before parsing account files.
    - Also added <project_name> element to account file so that we can
        display that correctly in message about project prefs

        - Added a new message type <reread_prefs/> to the
            core->app graphics segment
        - When the graphics framework (windows_opengl.C) gets this message,
            it calls an application function app_graphics_reread_prefs().
            This function can call boinc_parse_init_data_file() (see below)
            to get the new prefs
    - Core client: when get new project preferences,
        write new init_data.xml files for all running apps,
        and send them <reread_prefs/> messages.
        New functions:

    - Changed the way that user-supplied files (e.g. logos and images) work.
        OLD WAY: (see checkin by "Erik", May 19 2003)
            the scheduling server scans the user's project prefs
            and inserts <file_info> and <file_ref> elements
            into the <app_version> element,
            making it look like the user-supplied files are associated
            with the app.
            This necessitated the slightly kludgy "optional"
            attribute of FILE_INFO, so that slow-downloading
            user-supplied files wouldn't defer work indefinitely.
        NEW WAY:
            The scheduling server is not involved.
            PROJECT now has list "user_files" of FILE_REFS
            FILE_INFO now has an attribute "is_user"file"
            - When parse project prefs from account file,
                or when get new project preferences from server,
                convert <app_file> elements to entries in project.user_files
            - new function ACTIVE_TASK::link_user_files() makes links
                from slot dir to all user files that are present
            - when the download of a user file completes,
                tell running apps to reread prefs
                (they'll find the user file now)
            - garbage collection reference-counts user files
            - got rid of "optional" mechanism
        With this change, user-supplied images in graphics are updated
        dynamically when the user edits prefs on web,
        then does "Get Preferences" in core client
    - Handling of completed file transfers moved from
        PERS_FILE_XFER::poll() to CLIENT_STATE::handle_pers_file_xfers().
        (this job of PERS_FILE_XFER is to transfer the file,
        not deal with its contents)
    - changed benchmarks defaults from 1GFLOPs to 10MFLOPs;
        prevents slow computers from being inundated with work

David  4 Nov 2003
    - scheduler now respects disk usage limits.
        Scheduler request message now includes BOINC disk usage,
        both total and for this project.
        The scheduler parses user's global preferences
        to get disk-related prefs,
        and computes the max storage that can be used.
        It will send only as many results as fit within this limit.
        NOTE: this is still deficient in several ways:
            - it assumes that all results will use all their storage
                simultaneously.  It doesn't take into account that
                some results may use large storage while running,
                but not before or after.
            - it doesn't take into account storage that has been
                committed (to this or other projects) but not yet in use.
            - there's no mechanism for enforcing resource shares for storage,
                or for dynamic adjustment
    - print exit codes in both dec and hex

    - The following changes fix core client crashes that occur when
        reset a project, then quickly detach from the project
        while downloads are occurring.
        In once instance, this produced a state file that caused
        the client to crash each time it started up.
    - when parse an ACTIVE_TASK in state file,
        verify that the corresponding result is in the right state
        (RESULT_FILES_DOWNLOADED, with got_server_ack and ready_to_report false)
    - when parse a RESULT in state file,
        make sure it's consistent: in particular,
        if got_server_ack or ready_to_report is true,
        the state must be RESULT_FILES_UPLOADED
    - CLIENT_STATE::detach_project(): delete all the project's FILE_INFOs
        (reset_project() doesn't do this)

David  6 Nov 2003
    - cleaned up CPU time chaos
        OLD:
            An app measures and reports its CPU time when it calls
            boinc_time_to_checkpoint(), which may be infrequent.
            The reported CPU time is for the whole process
            (including graphics thread: wrong)
            If the core client doesn't get a message within 5 seconds,
            it measures app CPU time externally,
            with ACTIVE_TASK::get_cpu_time_via_os()
            (this can cause reported CPU time to jump up and down).
            Ambiguous function boinc_cpu_time(): does it return time for
            calling thread only?  time since WU start?
        NEW:
            An app measures and reports its CPU time every 1 sec,
            from the timer interrupt.
            The reported CPU time is only for the worker thread.
            Replace boinc_cpu_time() with:
                boinc_thread_cpu_time(): CPU time of calling thread
                    (also used by graphics_cpi.C to measure rendering time)
                boinc_wu_cpu_time(): CPU time of WU so far (for graphics thread)
            Notes:
            - The app no longer needs to call boinc_time_to_checkpoint()
                with any regularity
            - the timer interrupt handler runs on a different thread,
                so we record the worker thread handle.
    - use double rather than time_t in calculation of estimated completion
    - Code cleanup:
        removed some declarations from boinc_api.h
            (Don't declare internal functions in a .h file!)
        removed using_opengl, write_frac_done
        made things static that should be static

David  6 Nov 2003 (note: Eric's on the other side of the Int. Date Line)
    - Fixed bug that cause CPU time to jump whenever Get Preferences.
        It's because the app is getting a new aid.wu_cpu_time
        as part of reread_prefs;
        this is incorrectly added to the thread's CPU time.
        Solution: make a copy of aid.wu_cpu_time at startup and use the copy.

    - modify the scheduler so that if a client requests work,
        and there are unsent results, but none can be sent,
        then the client gets an explanatory message: either
            - no app version available
            - insufficient disk
            - insufficient memory
            - host is too slow
        This involved creating a WORK_REQ structure that gets passed
        around, to avoid huge numbers of arguments
    - modify the scheduler so that if either
        1) the shared-mem segment is absent or
        2) the DB can't be opened
        then it writes a "project temporarily down for maintenance"
        message instead of just exiting

    - Changes to a running app's checkpoint_cpu_time
        (as conveyed in shared-memory msgs)
        were not triggering state file writes.
        As a result the CPU time of a result was, in general,
        returning to zero after a reboot.
    - ACTIVE_TASK_SET::poll(): if any task's checkpoint_cpu_time has changed,
        trigger a client state file write
    - renamed ACTIVE_TASK_SET::get_cpu_times() -> get_status_msgs()
        Also, this function now returns boolean:
        whether any checkpoint_cpu_time has changed
    - renamed ACTIVE_TASK::get_cpu_time_via_shmem() -> get_status_msg()
        (since the message includes more than just CPU time)
    - removed ACTIVE_TASK.last_status_msg_time (not used)
    - factored out logic to compute frac_rate_of_change
        and put it in a separate function

    - Extend the "start" script to handle remote tasks.  Summary:
        - config.xml has a mandatory config.host element
            (for the project's main server)
            and optional task.host elements (default is main host)
        - Host X has its own run state file, run_state_X.xml
        - Host X has its own pid directory, pid_dir_X/
        - Host X has its own log directory, log_X/
        - Host X has its own lock file for "start", start.lock.X
        - run_daemons() etc. run tasks only for the current host
        - When run on the main host, start builds a list of other hosts
            and runs itself (with same cmdline, using ssh)
            on each of the other hosts.

        Notes:
        1) I didn't add <host>*</host> capability;
            it's not clear that we need this
        2) Output formatting could be improved

    - Fixed bugs involving buffer overflow of BLOB fields.
        These can be up to 65536 bytes in MySQL.
        MAX_BLOB_SIZE was defined as 4K.
        strcpy2() didn't do any buffer size checking.
        A team description was over 8K long.
        This caused db_dump to crash.
        Solution:
        - strcpy2() now defined as a macro that uses the sizeof()
            its destination, and doesn't overwrite it.
        - MAX_BLOB_SIZE replaced with 2 symbols:
            MEDIUM_BLOB_SIZE for fields used by BOINC
                defined as 4K so as to not increase shmem usage
            LARGE_BLOB_SIZE for fields with user-supplied text
                defined as 64K

    - We have the same gcc version problem with solaris that we do with
      linux whereby if the  version number of libstdc++.so on the run
      machine is different than that on the build machine, the loader
      fails.  However, on solaris you cannot just say gcc -static as there
      are dynamic only versions of some needed libs, namely libdl and
      libaio.  I tried to use the -Xlinker gcc option which theoretically
      should allow us to specify the link (collect2) line in precise
      detail.  But -lstdc++ kept showing up twice with one occurrence
      being outside my -Xlinker -B -Xlinker static directive.  So I
      hand crafted a collect2 line and placed it in a file - collect2_line.
      Sourcing this file produces an executable that will load and run
      across gcc versions (and solaris versions for that matter).  I
      don't like it but it works.

      IMPORTANT NOTE.  After sourcing collect2_line you have to
      re-"hard link" the executable boinc_client to a proper
      name with the correct version.

           <show selected window by turning on WS_VISIBLE style>

           The trouble with this technique is that it does not

    - added boinc_fopen() function.
       This should be used in lieu of fopen(), in both core client and apps,
       whenever opening a file for writing.
       This is because on Windows a utility program like FileFind
       might have the file open at that exact moment,
       and your fopen() will fail.
       boinc_fopen() deals with this by sleeping for 3 seconds and trying again.
       NOTE: in SETI@home there's a much fancier function
       that does exponential backoff up to one hour.
       Can't do that here, in part because the GUI requires
       the core client to be nonblocking.

    - Fixed errors in deciding whether more work was needed,
        and if so how much.
        This caused a situation where hosts would repeatedly
        ask the server for more work
        (which, because of recent anti-spam mechanism, would return no work)
        The error involved the confusion of two quantities:
        1) work buffer
            This is an estimate of the time (measured in days)
            until this host will finish all current work.
            It reflects the host's "active_frac" and the # of CPUs.
        2) CPU time
            This is an estimate of the CPU time a WU will take on this host.
            It does not reflect active_frac or # of CPUs
        Example error: current_work_buf_days() didn't reflect active_frac and ncpus.
        So we underestimated the work buffer, and requested work inappropriately.

        NOTE: the <work_req_seconds> field in a request message
        is in units of CPU time, NOT work buffer

    - Fixed errors in estimating the wallclock duration of a WU
        (used in feasibility test in scheduler):
        Should divide, not multiply, by active_frac;
        should not multiply by # cpus
    - add a "deprecated" flag to app_version.
        If you decide that a particulate app_version has problems,
        you can deprecate it.
        The scheduler advertises the latest non-deprecated version.
        NOTE: this only is effective if core clients have the following:
    - Changed the policy assigning an app_version to a WU
        Use the version included in the scheduler reply,
        and if there is none, use the latest version.
        This means that if a project deprecates an app_version,
        clients won't use it.

    - Check for buffer reallocation errors in MFILE functions and return values
      that mimic the normal system versions of these functions.

      Functions that were changed:  * indicates a change.
    function        successful return    failure return
    --------------        ------------------    --------------
    MFILE::printf()        num bytes output    -1 *
    MFILE::write()        num bytes output    -1 *
    MFILE::putchar(c)    c                 EOF *
    MFILE::puts(s)        strlen(s) *        EOF *

      MFILE::puts() used to return 0 on success.  I greped both astropulse
      and seti_boinc code and found no current use of this function.

    - Made the basic test script (test_uc.py) work again:
        - fixed syntax errors in SQL files
        - initial config.xml file includes <host> element
        - back-end processes handle SIGHUP, not SIGINT
            (we changed in "start"; need to change here too)
        - "MIN_SENDWORK_INTERVAL" is read from config.xml (default 0)
        - added 12-second sleep in run_check_all()
            (based on 10-sec sleep in assimilator; should reduce)
    - The user and admin web interfaces now work in the basic test case
        (i.e. you can use html_ops to look at DB contents)

    - Added Python assimilator, courtesy of Stephen Pellicer
        All the back-end programs could be implemented in Python;
        CPU usage is a non-factor.
        Some people might prefer this to C++.
        No reason not to have both, as long as the logic stays in synch.

    - Fixed error in windows client initial startup after a clean
      install. Default wait time before initial server request was
      too long (3 minutes).
