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.

- 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.
- GUI client should display "Upload failed" and "Download failed"
in transfers tab when failure occurs
- GUI: 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
- Win GUI: line between menus and tabs

- trim leading/trailing spaces from account ID (Win GUI)
- 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?
- 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
"Add project" behavior:
Goal: give user timely feedback if bad project URL or account ID;
don't leave bad project files sitting around
A project addition is "successful" when
1) the client fetches the master page,
2) the master page has at least one scheduler URL
3) the client contacts a scheduler and gets a user name back.
The cmdline and GUI clients need to inform the user if a project
add is not successful, since it probably means the master URL
or account ID were typed in wrong.
A project is "tentative" if the above hasn't happened yet.
This is flagged in the project file (<tentative/>) and in memory
A "failure event" is
- master fetch fails
- master page has no scheduler URLs
- scheduler RPC fails
- scheduler RPC returns no user name
A "success event" is
- scheduler RPC returns user name
cmdline client
first time (no projects initially) or -add_new_project flag:
new project is tentative (write flag to project file)
if failure event occurs for tentative project:
project_add_fail(PROJECT&)
print "check URL and account ID" message
delete project file
exit
If success event occurs for tentative project
project_add_succeed(PROJECT&)
clear tentative flag, rewrite account file
GUI client:
first-time dialog or "attach to project" command:
show a modal dialog
("verifying account" w/ "cancel" button)
project_add_fail(PROJECT&)
replace w/ modal error dialog w/ retry, cancel
project_add_succeed(PROJECT&)
Delete files if needed to honor disk usage constraint
should include per-result constraints (e.g. giant stderr files)
