The core SQLite source code is free (as in beer, as in freedom), but its development is carefully controlled by Hwaci, the company responsible for employing SQLite developers. Hwaci also owns the trademark to the name SQLite. Hwaci has several products, including extensions such as the SQLite encryption extensions, that are NOT free (as in beer, nor as in freedom). The testing system used for SQLite, which represents a source base several times larger than the SQLite core, is also completely private. Hosting such systems on Github would require a subscription fee and, frankly, why should they bother? -j ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users

[sqlite] SQLite 3.21 on IBM Mainframe - z/OS
Hello,
SQLite 3.21 autoconf (sqlite-autoconf-321.zip) compiles and runs
successfully on z/OS 2.2 with few minor modifications which I would like
the developers to consider for integration into the code base.
Namely:
1 - In sqlite3.c, in the code section coming from tokenize.c, the EBCDIC
version of the aiClass[] array defines codepoint 0x15 as class '27'
(CC_ILLEGAL). In EBCDIC (both codepages 037 and 1047, the most common
ones) 0x15 is actually NL (newline) and should be defined as class '7'
CC_SPACE to allow the tokenizer to properly manage multi-line statements.
There are minor issues in the Makefile generated by ./configure:
2 - The ./configure process wrongly detects the presence of the posix
fallocate function, which is not actually available ("checking for
posix_fallocate... yes"), and sets -DHAVE_POSIX_FALLOCATE=1. It should
be -DHAVE_POSIX_FALLOCATE=0. I don't know why this happens as I was not
able to understand what the check does. I will be happy to help
debugging it if guided.
3- In order to successfully compile sqlite3, the C compiler command
(CC=..) should be changed from cc to xlc; the CFLAGS option should be
set to "CFLAGS = -g -qFLOAT=IEEE -qstrict -qdll" and
"-D_XOPEN_SOURCE=600" should be added to the current DEFS.
If needed I have a diff generated pach for 1) and another one for 2) 3)
to make the required changes better understandable.
With these changes the process to build sqlite is as simple as:
1- Upload a non compressed tarball of the autoconf version of SQLite to
a file in your OMVS environment (let say the file is called
sqlite-autoconf-321.tar)
From your OMVS shell issue the following commands
2- pax -ofrom=iso8859-1,to=ibm-1047 -rf sqlite-autoconf-321.tar (the
"to" codepage in the pax command must be set to your actual EBCDIC codepage)
3- ./configure --enable-dynamic-extension (I need this option myself but
of course it is not mandatory)
4- for the time being manually apply the changes described above
5- make
Et voilà.
At the moment I am testing with the sqlite3 cli, and I can perform
normal operations and load and use dynamic extensions.
I will keep testing and I will report other issues if any.
Hope this helps,
mario

As stated, SQLite is managed by Fossil, and Fossil is managed by SQLite.

Re: [sqlite] Move to Github!!?
SQLite source is managed in a Fossil (not Git) repository, which is software itself designed by Dr. Hipp and based on SQLite. GitHub would be an entirely inappropriate venue. SQLite is also not open source software in the conventional sense. SQLite is written by a small team of people, and outside contributions are far less common than in most open source software.

[sqlite] LSM extension lsm_work
Hi all, I am very happy with the inclusion of LSM extension in sqlite3's code base. I have a question regarding the merging of segments within the database. I noticed that autowork enabled was not enough for keeping disk consumption at bay, the generated database was N times larger than the generated by sqlite3. Using lsm_work(db,1-1,0) after every transaction seems to mitigate this and the disk footprint of the db gets back to normal. This seem to be explained by Mr. Kennedy here http://www.sqlite.org/src4/doc/tip/www/lsmusr.wiki#explicit_scheduling * What does exactly do lsm_work(db,1,-1,0) ? My assumption is that it merges all the on disk segments into one larger segment, is this correct? * Doing this after every transactions of course takes some tool on performance and everything goes significantly slower. What is the best way of running lsm_work? in a separate thread like it is mentioned in sqlite4's documentation? http://www.sqlite.org/src4/doc/tip/www/lsmusr.wiki#explicit_scheduling * Finally, can I call lsm_work less aggressively in terms of parameters? I am worried about virtual memory consumption so I'd rather not do a full lsm_work every time, something like.. merge until there are no more elements with delete markers on it?
