[Monetdb-announce] RFC: Preparing a new "stable" MonetDB 4.3.16
by Stefan.Manegold＠cwi.nl 03 Mar '04

03 Mar '04

Dear MonetDB user and developers, given the growing MonetDB community, it becomes ever more important to have a proper version management for and properly made "stable" versions of MonetDB. The purpose of this mail is to (1) initiate a new approach that tries to find a compromise between "user needs" and available "developer and maintainer man-hours"; and (2) ask for feedback, discussion, and ideas about this approach that will hopefully lead to an "even better" solution ;-) Well, here are my late-night ideas: To have a common starting point, I just tagged the most recent CVS version of MonetDB as "MonetDB_4-3-16_rc01", i.e., it's supposed to be the first release candidate for the to-be-made new "stable" MonetDB-4.3.16. I'd like to encourage all MonetDB "users" of you to spend some (spare?) time to download this version, and test it with you usual MonetDB tasks. Well, as usual, there is of course now "guarantee", hence, it might be a good idea to have this version running next to your current "stable"/"production" version of MonetDB, rather than immediately replacing the latter. Yes, there will be things that work differently, or do not work at all (without any changes on your side). I kindly ask you, to report all these issues to us "developers", preferably as bug reports and feature requests via SF or simply via mail to monet(a)cwi.nl. Since we ("developers") have no complete overview of your ("users") local setting, we need your help in making the next stable version of MonetDB both stable and convenient to use for you. Moreover, this kind of "beta-testing" extends our usual automatic testing that we do every night anyway. So far, we can only say that a stable version is/was "stable" with respect to the test set we use for automatic testing (cf. http://monetdb.cwi.nl/TestWeb) However, not all aspects of MonetDB are covered by the tests, yet(?). We will added as many of your reports as possible to the test set, hence (most of) the "beta-test" will become automatic in the future. However, various scenarios simply cannot be reproduced in the automatic testing, e.g., as they require a setup that is simply too big or runs too long. Hence, please do help us, and you'll (hopefully) eventually be rewarded with a new "stable" MonetDB that deserves this attribute from the very day of its birth. Now to you fellow developers and maintainers ;-) Next to helping out in fixing the floods of bugs that will be sent towards us after the request above, my major question is about your plans for current and future developments: Which new features should be in 4.3.16 and which can/should better wait until thereafter. The main reason for this question is, that we should provide clear cuts to the users, which features are in which version of MonetDB. Timing: Given some "external constraints" (;-), I plan to release the "user-tested" ("user-approved"?) MonetDB 4.3.16 no later than April 14 2004, i.e., in about 6 weeks. So please keep this in mind when planning your contributions in the above scenario. During these 6 weeks, we will tag further release candidates and ask users for help in testing them (at least on all those tests/scenarios we could not add to test automatic test set for whatever reason). Ok, this is my first late-night shot about this issue. As I said, it's just a proposal. Nothing's carved in stone, yet (apart from this mail and the CVS tag ;-), so please do comment on this and state your opinion, what ever it might be! Thank you very much in advance!

[Monetdb-announce] Updated (reasonably) stable (pre-)release: Monet_4-3-14c
by Stefan.Manegold＠cwi.nl 06 Nov '03

06 Nov '03

Updated (reasonably) stable (pre-)release: Monet_4-3-14c ======================================================== Dear MonetDB-Users, I just applied all recent changes from the main (development) branch of MonetDB to the "Monet_4-3-14" stable branch. This updated stable version is now called "MonetDB 4.3.14c". For details on how stable it indeed is, have a look at our "Test-Web" at http://monetdb.cwi.nl/intern/ and/or browse the open bug-reports on SourceForge at http://sourceforge.net/projects/monetdb/ If you do already use "MonetDB 4.3.14" (i.e., the "Monet_4-3-14" stable branch), simply run cvs update -dP in your top-level source directory to get the new version. Users of all older version should eventually step-over to "MonetDB 4.3.14c"; simply run cvs update -dP -rMonet_4-3-14 in your top-level source directory to get the new version. Please let me know in case you need help with this. To checkout the new branch from scratch, do cvs -z3 $YOURCVSROOT co -rMonet_4-3-14 MonetDB where YOURCVSROOT="-d:pserver:anonymous@cvs.monetdb.sourceforge.net:/cvsroot/monetdb" if you're using anonymous pserver checkout, or YOURCVSROOT="-d:ext:developername@cvs.monetdb.sourceforge.net:/cvsroot/monetdb" if you have a sourceforge account to checkout via ssh. Development continues on the main branch, which still carries the version number "4.3.15". As usually, significant bug fixes should go to both, the main branch and the Monet_4-3-14 branch. Changelog/Benefits ------------------ The main reason for this updated stable release are a bunch of bug fixes that have been implemented during the last four weeks. Most of them should not affect users in any other way than that MonetDB now compiles and runs better on all supported platforms. For details have a look at the "change logs" at http://monetdb.cwi.nl/intern/, or contact the respective developers. Two changes might affect your applications using the C-API of MonetDB: =================================================================== 2003/10/28 - sjoerd: src/common/stream.mx src/gdk/gdk_atoms.mx src/gdk/gdk_bbp.mx src/gdk/gdk_storage.mx src/gdk/gdk_utils.mx src/mapi/mapi.mx src/mapi/clients/C/Mapi.mx src/modules/contrib/vector.mx src/modules/contrib/wisc.mx src/modules/plain/ascii_io.mx src/modules/plain/enum.mx src/modules/plain/kernel.mx src/modules/plain/streams.mx src/monet/monet_client.mx src/monet/monet_deparse.mx src/monet/monet_parse.mx src/monet/monet_process.mx Changed interface to streams: If you have a stream *s, you now have to call the following functions to read/write/etc with the stream: stream_read(s, buf, elmsize, cnt) stream_write(s, buf, elmsize, cnt) stream_close(s) stream_destroy(s) stream_error(s) stream_flush(s) stream_name(s) stream_errnr(s) stream_byteorder(s) instead of the old way which was s->read(s, buf, elmsize, cnt) s->write(s, buf, elmsize, cnt) s->close(s) s->destroy(s) s->error(s) s->flush(s) s->name s->errnr s->byteorder The advantage of this change is that you only need to specify the stream value once (elimintating potential, hard-to-find bugs); the stream implementation can be completely hidden. If you need the old interface, uncomment the define for BACKWARD_COMPATIBLE_STREAM_DEFINITION in src/common/stream.mx. =================================================================== 2003/10/31 - sjoerd: src/mapi/clients/C/Mapi.mx src/mapi/clients/C/MapiClient.mx src/mapi/examples/C/sample0.c src/mapi/examples/C/sample1.c src/mapi/examples/C/sample2.c src/mapi/examples/C/sample3.c src/mapi/examples/C/sample4.c src/mapi/examples/C/smack00.c src/mapi/examples/C/smack01.c Changed API of mapi_connect. Before the prototype was Mapi mapi_connect(char *host, char *username, char *password, char *lang) where host is actuall host:port; not the prototype is Mapi mapi_connect(char *host, int port, char *username, char *password, char *lang) where host is just host and the port is a separate parameter. The sample scripts now expect a separate host and port argument (in as far as they expected a combined host:port argument). =================================================================== Caveat ------ Martin's *new* MAPI functionality in not exhaustively tested, yet, and hence not guaranteed to work. However, all old functionality *should* work as expected. Extra modules and front ends ---------------------------- With "MonetDB 4.3.14c" and "MonetDB 4.3.15" being identically right now, the HEAD version of all extra modules and front ends that are publicly available (sql, template) or used within CWI, only, (xml, gis, acoi, misq, times100, playpen, pruning) (are supposed to) compile with both. This might change as soon as the is need to apply changes in the main (development) branch of MonetDB that will break the compatibility. Such changes should hence not be propagated to the stable "Monet_4-3-14" branch (unless *all* extra modules and front ends are immediately updated accordingly). Likewise, any no changes to the extra modules and front ends that break compatibility with "MonetDB 4.3.14c" should be checked in to their respective main branch, unless all developers of that extra module or front end agree on abandoning compatibility with "MonetDB 4.3.14c" and moving forward to "MonetDB 4.3.15". Testing ------- The daily testing will continue as is: The main branches (MonetDB and all extra modules and front ends) & are tested each night. During the weekend, the main (development) branches of all extra modules and front ends will additionally be tested together with the stable "Monet_4-3-14" branch. In case you have any questions, comments, problems about/with Monet_4-3-14, please feel free to contact me.
