David A. April 10 2002
Initial checkin of all files.
The system is fairly feature-complete and
runs a number of test cases correctly.
Currently runs only on Linux.
David A. April 11 2002
- Got things to compile on Solaris.
- Pass in platform name, version number from Makefile
(platform name comes from configure)
David A. May 15 2002
- Allow applications to have multiple files
(e.g. scripts, libraries, pre- and post-processing programs).
The app_version table now has an xml_doc field,
which contains a list of <file_info> and <file_ref> elements.
Note: the utility for adding applications (tools/add.C)
still handles only single-file applications.
- Changed IO_FILE_DESC to FILE_REF since it now represents
an association of a file to workunit, result or application

David A. May 23 2002
- Change the scheduling server to reduce database accesses.
There's now a shared-memory segment that contains
1) the platform, app, and app_version tables in their entirety;
2) a fixed-size set of results ready to be sent,
and their corresponding workunit.
This segment is initialized and maintained by a new program
called the "feeder" (sched/feeder.C) that should run
whenever the scheduling server is up.
Note: the scheduler still needs to be converted to fast CGI
- Added handy interfaces for dealing with shared memory and semaphores.
- Changed to utilities and scripts used for testing so that all
server-specific names (paths and URLs) come from environment
variables instead of being hardwired in the code.
You'll want to add these to your .tcshrc or whatever.
See the doc/install.html for details.

files db/dependencies and client/config.status and client/config.log
removed. These are build time files and should not belong
in the source tree. They confuse subsequent builds.
files updated: configure configure.in api/Makefile.in
apps/Makefile.in client/Makefile.in db/Makefile.in
db/mysql.h lib/Makefile.in sched/Makefile.in
tools/Makefile.in
These Makefile.in changes will allow the build to be performed
outside the source tree. This is convenient for several
reasons. The number one reason is that this allows the source
tree to remain untouched by the build and therefore clean.
This will prevent garbage build files from being checked in
during a 'cvs commit'
To run a build outside the source tree, simply make an object
directory anywhere else that you would like to work, then just
execute the configure script in the top-level boinc directory.
$ mkdir boincobj
$ cd boincobj
$ <... path to source tree ...>/boinc/configure
$ make > make.out 2>&1 &
Note the examples in apps/Makefile.in and sched/Makefile.in
of how to use the top_srcdir variable to locate include files
in the source tree outside of the current directory. Local
references to other object files and libraries produced by
the build remain as local .. references.
The change to configure.in, (and thus configure) and db/mysql.h
allow a proper identification of where the mysql .h files live.
The SSL location of /usr/local/mysql/include is a bit non-standard.
Most systems will have these in /usr/local/include/mysql
Hiram C. Sat May 25 09:20:25 PDT 2002
Continue updating:
Makefile.in config.guess configure configure.in api/Makefile.in
apps/Makefile.in client/Makefile.in client/config.guess
client/configure client/configure.in sched/Makefile.in
tools/Makefile.in
I have almost clean builds now on Solaris, Mac OS X,
and UnixWare. There appears to be a missing sched_shmem.h
file from the source tree.
There is still cruft in this configure system. I will continue
to work on it to clean it up.
David A. May 29, 2002
- Mostly implemented support for editing preferences,
including project-specific preferences.
Simplified the preferences scheme.
Abandoned the idea of multiple preference sets per user;
each user now has a single set of preferences.
Got rid of the "prefs" database table;
prefs are now just an XML and mod_time field in the user table.
Haven't tested much yet.
NOTE: these new features use the XML parsing features of PHP.
This means that, on the BOINC web server,
you must configure PHP with the --with-xml option,
and you must make and install Apache.
Also, you probably need to use a recent version of PHP;
XML parsing was broken in PHP 4.0.4, but it works in 4.2.1.

Hiram C. Thu May 30 01:28:47 PDT 2002
updating: client/configure client/configure.in
client/net_xfer.C sched/Makefile.in sched/feeder.C
This now builds just fine on Solaris, Linux and OpenUnix8.
And only two tiny errors remain for a Mac OS X build.
That being the specification of g++ in the sched/Makefile
and statvfs() is not available on the Mac for

- Ensure that preferences propagate from the server
where they are updated to all hosts,
Eliminated concept of "home project".
Not tested yet.
Also to do: replace the "accounts.xml" file with
a file containing preferences.
- Changed the way the client handles preferences.
It now saves saves the exact XML it gets from the server,
regardless of whether it can parse it all.
- Fixed client parsing code to reflect new names for preferences
- Changed the way the scheduling server handles prefs in
a client/server interaction.
If it gets newer prefs, it updates its own DB.
If its DB has newer prefs, it sends them to client.
- Fixed the test scripts so that they start/stop the feeder also.
This required adding a "ready" flag to the shared-mem structure
so that the scheduling server can find out if the feeder hasn't
finished initializing the structure.
Also required adding a "-synch" cmdline option to feeder.
- added utility program (sched/show_shmem.C) for looking at
scheduler shared memory
- renamed "types.*" to "client_types.*" to avoid name conflict
with system include files

- added support for multiple URLs in a FILE_INFO
(e.g. multiple servers from which the file can be downloaded)
- started work on "persistent file transfer": a layer on top of
FILE_XFER that manages restarting from failed connections,
and that implements a give-up policy
- added offset arguments to GET and PUT HTTP operations.
NOTE: this will work fine for downloading files (GET)
but we'll have to use something else for upload,
since the standard PUT handler doesn't do offsets,
and we need security functionality in any case.
- added preliminary version of application API for
communicating with core client.
- use <file_ref> tags instead of <input_file> and <output_file>
(makes things simpler)

- Replaced the "accounts.xml" file with the user preferences ("prefs.xml").
All non-host-specific project info is stored in this file;
all host-specific project info is in client_state.xml.
The PROJECT class is a union of the two.
The logic for dealing with inconsistencies between
prefs.xml and client_state.xml, and with updating in-memory
and on-disk project lists in response to an update from a server,
are a little tricky and are described in the code.
- The prefs file can be overwritten by <preferences> in a scheduling
server reply. To prevent buggy servers from zeroing out
users' project lists, the client makes sure there's at least
one project, and backs up the old prefs.xml into a timestamped file.
- The command-line client, if prefs.xml is absent,
prompts the user for a project URL and authenticator,
and creates an initial prefs.xml.
- Each project now has a "master URL", with is its home page
and also contains <scheduler> elements giving the URLs of
its scheduling servers.
- Added a class SCHEDULER_OP which encapsulates fetching and
parsing a project's master page (if necessary),
then making an RPC to one of its scheduling servers.
TODO: add retry and failure logic.
- A project can have more than one scheduling server.
TODO: use all of them.
- Project directories are stored in URL-encoded form.
This allows project master URLs to have slashes, which is a necessity.

- Added support for upload authentication.
This prevents bad guys from filling up data servers with trash.
In this scheme, each <file_info> element sent from
server to client includes a <max_nbytes> field limiting
the size of the file, and includes a digital signature
based on the project's "upload authentication" key pair.
File uploads, instead of being done by PUT, are now done by POST
to a CGI program, "file_upload_handler".
The request header includes the signed <file_info>,
and the CGI program verifies the signature and enforces the size limit.
The affected pieces of code:
- Added a function create_keys() in PHP test scripts
to create encryption keys. Call it from all script.
- Added environment var BOINC_KEY_DIR saying where keys are kept.
- The client must maintain an exact copy of each <file_info> XML,
and of the signature, so that it can send to upload server.
- Added a new variant of HTTP operation, HTTP_OP_POST2.
The existing variants all use single files for request and reply.
The new variant (used for file upload) has a request
consisting of a memory block followed by (part of) a file;
the reply is in memory.
This avoid copying possibly huge upload files.
- FILE_XFER objects now take a FILE_INFO as initialization argument;
needed to convey authentication info.
The upload variant creates and sends the authentication header.
- Result templates now include a <max_nbytes> in each
<file_info> element, and the URLs refer to the
file_upload_handler (with no filename)
- process_result_template() works differently, since it must
generate a digital signature at the end of each <file_info>
- create_work expects the name of a private key file.
- Added crypt/md5 functions to sign/verify in memory,
encode/decode ASCII data in memory, checksum in memory
- Change "gmake" to "make" in top-level makefile.
(alias make to gmake if this is a problem)

David A. July 7, 2002
- Added code signing. All files associated with an app version
(i.e. all executable files) must now be signed
with the project's "code sign key". The components include:
- PROJECT has new field "code_sign_key", keep track of project's
public code-signing key.
Send this on each scheduler RPC.
- The scheduling server stores the public code-signing key in memory.
Send it to any client who doesn't have it.
If the client has an old key,
send them the new key signed with the old key.
NOTE: this uses a scheme in which signatures are kept
in files on the server, to avoid keeping private keys
in online machines. This should be documented.
- The utility to add new app versions (add.C) adds a signature
to the FILE_INFO element.
NOTE: eventually the signing should be done offline.
- FILE_INFO has a new boolean field "signature_required";
set for all files associated with an app version
- FILE_INFO has a new char* field "file_signature",
which is the digital signature.
Renamed upload authenticator from "signature" to "xml_signature"
to avoid confusion.
- Add function verify_downloaded_file(), called after every download;
does MD5 or signature checking as needed.
- Added some new functions for signature checking etc.
- the client is now linked with the crypt library
- Server-side errors should always include the name of the
CGI program generating the error (scheduler or file upload handler)
