Hi all
(Cross-posted to oqgraph-developers, maria-developers)
I am trying to track down a segfault apparently triggered by concurrent
execution of queries through OQGraph - for context, see:

I am however a bit confused as to what is going on, becau
Awesome job!
I note the last tag is mariadb-10.0.10; just wondering if say I fix a bug or
make an improvement (in my case, in oqgraph) and make a pull request against
this repo, what the procedure would be for backporting to 10.0.12 say?
Would the process be as simple as generating a patch from t

Hi Amith
the O'Reilly book MySQL Internals has a chapter on developing storage engines,
e.g. Chapter 7. The Storage Engine Interface. This book is geared to MySQL
not MariaDB but the concepts are much the same.
There is also https://dev.mysql.com/doc/internals/en/custom-engine.html, again

I managed to get mysqld to run in this context using strace.
(Aside - took a bit of trickery using a secondary script, because although
mysql_install_db lets you choose the program to run for mysqldb it is quoted
and so you cant just use 'strace mysqld' as the exec)

Hi,
I dont know enough about that issue to have a proper opinion; but in, my case
at least, /var/lib/mysql is not on a tmpfs filesystem so I dont understand why
the error is triggered. If Maria is creating other tmp files and failing,
then should those filenames instead be reported on the error

Hello Ian
I just tried to repeat what you found and I got the expected value for weight
(weight=4) in my output.
However I think it quite probable there is a bug that manifests under the
right conditions, so I need you to provide some configuration information:
* your system (32-bit, 64-bit, num
Hi,
I like to build MariaDB in a separate directory to keep the source tree clean.
This works for me as follows:
cd path/to/maria/source
mkdir mybuildir
cd mybuildir
cmake .. "-DWITH_PLUGIN_ARIA=1 (etc...)"
make
mysql-test/mysql-test-run --suite oqgraph (etc)
However when I want to
Hello all
just joined the development list recently, looking at doing a little bit of

Apologies in advance if this is the wrong list to ask my question.
I have been working through the information at
https://kb.askmonty.org/en/Getting_the_MariaDB_Source_Code/ and related pages.
