----------------------- BUGS (arranged from high to low priority) ----------------------- - Client treats URL "maggie/ap/" different than URL "maggie/ap", though this isn't really a bug it might be good to fix anyway - global battery/user active prefs are always true in the client - Client should display "Upload failed" and "Download failed" when failure occurs - Result status should say "downloading files", "uploading files", etc. - message window should reposition to bottom when new message - show_message should expect \n, discard it if GUI - show "---" for CPU time, %done of results not started yet - Win GUI: line between menus and tabs - message for client starting or exiting - "show graphics" should not use right-click - win GUI: reduce flicker? - on major version change, should discard any pending WUs - labels on disk graph are not clear - document and add to global prefs? start_saver run_minimized run_on_startup hangup_if_dialed - trim leading/trailing spaces from account ID (Win GUI) - astropulse wanted to display screensaver graphics when it wasn't supposed to, causing the screen to flicker wildly and uncontrollably until ap.exe was killed This happened on 98 and 2000. recreate using Display Properties, preview - I entered in a wrong URL - there was no obvious feedback that it wasn't correct. Messages showed up in the messages tab, but I was looking at the progress tab. Shouldn't the client expect something from the server? If it doesn't get it, especially on logging in for the first time, you should get an obvious warning. - when i quit a project, I have to exit and restart the client, which is ugly. - after quitting a project, the project name still showed up in gray in the projects list - I could right click on it to "relogin" (which did nothing) or "quit project" which I thought I already did. - consider warning message during windows (and perhaps other platforms) install that checks to see if the BOINC directory already exists, and if so, should the user overwrite it? or upgrade it? - Screensaver on win98 shows up as "boinc_ss" in the screensaver list. Should be "BOINC" - When previewing the screensaver (on Win98) I had the AP graphics already on on the desktop - the screensaver just shows a bouncing "B" icon. Should that happen? - After running all night (on Win98) I shook the mouse to wake up the blank screen, and all I saw was the top half of the screen was solid gray, and the bottom half the bottom half of the astropulse graphics. They weren't moving. The computer was frozen. I had to ctrl-alt-del to restart. ----------------------- HIGH-PRIORITY (should do for beta test) ----------------------- On "add project" the core client should immediately attempt to get project master page and verify user account. If failure, let user retype URL/ID test cpu-counting on red hat Delete files if needed to honor disk usage constraint should include per-result constraints (e.g. giant stderr files) inform user if files deleted - "Connect Now" command should apply to a particular project, and should override the backoff on that project implement server watchdogs ----------------------- THINGS TO TEST (preferably with test scripts) ----------------------- time-of-day limitation Limit frequency of disk writes make sure it actually works - Test suspend/resume functionality on Windows/UNIX - verify that if file xfer is interrupted, it resumes at right place - result reissue - WU failure: too many errors - WU failure: too many good results - credit is granted even if result arrives very late - multiple preference sets - shared memory and CPU time measurement, with and without the BOINC API - timezone on all platforms - preference propagation between projects - ensure cpu time doesn't reset if app is killed rather than quitting ----------------------- MEDIUM-PRIORITY (should do before public release) ----------------------- add an RPC to verify an account ID (returns DB ID for user) needed for multi-project stats sites implement a "clear project" command (GUI and cmdline) implement a "fetch prefs" command (regular RPC w/o work request) all RPCs should return a "user-specific project URL" to be used in GUI (might refer to user page) screensaver should say (in text below logo) if - core client isn't running - core client running, but in no-work period - in work period, but no app w/ graphics to run when you create a team you should join that team in GUI, project name should hyperlink to a project-specified URL (typically user page for that project) preference flag for confirm before accepting executable file abort result if any file exceeds max_nbytes per-WU limits max disk max CPU max VM size Don't fork CPU benchmark process if skip_cpu_benchmarks is set let user choose language files in installation process write general language file manipulation functions use https to secure login pages, do we care about authenticator being transmitted without encryption from the client? abort app if excess memory used Astropulse memory leak on Linux/Solaris? Windows 9x CPU time calculated incorrectly write docs for project management how to start/stop server complex what needs to be backed up and how account creation: show privacy/usage policies finish SOCKS implementation, test decide what to do with invalid result files in upload directory make get_local_ip_addr() work in all cases think about sh_fopen related functionality in BOINC client Implement FIFO mechanism in scheduler for results that can't be sent user profiles on web (borrow logic from SETI@home) Devise system for porting applications password-protected web-based interface for uploading app versions and adding them to DB XXX should do this manually since need to sign Add 2-D waterfall display to Astropulse Deadline mechanism for results - use in result dispatching - use in file uploading (decide what to upload next) - use in deciding when to make scheduler RPC (done already?) Testing framework better mechanisms to model server/client/communication failure better mechanisms to simulate large load do client/server on separate hosts? Global preferences test propagation mechanism set up multi-project, multi-host test; change global prefs at one web site, make sure they propagate to all hosts Per-project preferences test project-specific prefs make example web edit pages make app that uses them set up a test with multiple projects test "add project" feature, GUI and cmdline test resource share mechanism CPU benchmarking review CPU benchmarks - do they do what we want? what to do when tests show hardware problem? How should we weight factors for credit? run CPU tests unobtrusively, periodically check that on/conn/active fracs are maintainted correctly check that bandwidth is measured correctly measure disk/mem size on all platforms get timezone to work CPU accounting in the presence of checkpoint/restart test Redundancy checking and validation test the validation mechanism make sure credit is granted correctly make sure average, total credit maintained correctly for user, host Windows screensaver functionality idle-only behavior without screensaver - test Data transfer make sure restart of downloads works make sure restart of uploads works test download/upload with multiple data servers make sure it tries servers in succession, does exponential backoff if all fail review and document prioritization of transfers review protocol; make sure error returns are possible and handled correctly Scheduler Should dispatch results based on deadline? test that scheduler estimates WU completion time correctly test that scheduler sends right amount of work test that client estimates remaining work correctly, requests correct # of seconds test that hi/low water mark system works test that scheduler sends only feasible WUs Scheduler RPC formalize notion of "permanent failure" (e.g. can't download file) report perm failures to scheduler, record in DB make sure RPC backoff is done for any perm failure (in general, should never make back-to-back RPCs to a project) make sure that client eventually reloads master URL Application graphics finish design, implementation, doc, testing size, frame rate, whether to generate Work generation generation of upload signature is very slow prevent file_xfer->req1 from overflowing. This problems seems to be happening when the file_upload_handler returnes a message to the client that is large. This causes project->parsefile to get wrong input and so on. test HTTP redirect mechanism for all types of ops Add batch features to ops web ----------------------- LONG-TERM IDEAS AND PROJECTS ----------------------- use https for login (don't sent account ID or password in clear) CPU benchmarking This should be done by a pseudo-application rather than by the core client. This would eliminate the GUI-starvation problem, and would make it possible to have architecture-specific benchmarking programs (e.g. for graphics coprocessor) or project-specific programs. investigate binary diff mechanism for updating persistent files verify support for > 4 GB files everywhere use FTP instead of HTTP for file xfer?? measure speed diff Local scheduling more intelligent decision about when/what to work on - monitor VM situation, run small-footprint programs even if user active - monitor network usage, do net xfers if network idle even if user active The following would require client to accept connections: - clients can act as proxy scheduling server - exiting client can pass work to another client - client can transfer files to other clients User/host "reputation" keep track of % results bad, %results claimed > 2x granted credit both per-host and per-user. Make these visible to project, to that user (only) Storage validation periodic rehash of persistent files; compare results between hosts Include account ID in URL for file xfers This would let you verify network xfers by scanning web logs (could use that to give credit for xfers) WU/result sequence mechanism design/implement/document Multiple application files document, test Versioning think through issues involved in: compatibility of core client and scheduling server compatibility of core client and data server compatibility of core client and app version compatibility of core client and client state file? Need version numbers for protocols/interfaces? What messages to show user? Project? Persistent files test design/implement test reporting, retrieval mechanisms (do this using WU/results with null application?) NET_XFER_SET review logic; prevent one stream for starving others Kill app if there is a memory leak Other user preferences: memory restrictions process priority/affinity show disk usage as two pie charts (one for overall, one for per project)
