Yes, GET DIAGNOSTICS is in 5.5 (and anyway, a workaround for older versions should be possible, correct?). Some comments: 1) The LIFO tables sounds to me a little dangerous. Of course "asynchronous" means "asynchronous", but under certain circumstances some queries could wait too much... don't you agree? Maybe the direction could depend from an option... 2) SELECT queries are "materialized", which is cool. But I don't understand how the user can associate an async query with the results table. 3) In MariaDB, the P_S is disabled by default, and a user can still disable it in MySQL. Also, in MariaDB global_status is in I_S, while MySQL has it in P_S (another funny incompatibility developed by Oracle). The first problem can probably be addressed with CONNECT (SRCDEF='show processlist') and the second with a view in async schema. Would you accept a patch? Probably more comments/questions will come. In the meanwhile, thanks for your work (again). bye Federico -------------------------------------------- Mer 24/2/16, Justin Swanhart <greenlion(a)gmail.com> ha scritto: Oggetto: Re: [Maria-discuss] New Question: Non-blocking calls from PHP A: "Federico Razzoli" <federico_raz(a)yahoo.it> Cc: "Maria Discuss" <maria-discuss(a)lists.launchpad.net> Data: Mercoledì 24 febbraio 2016, 16:04 Hi, It is completely native. It consists of a queue table, a thread state table, a settings table, a stored procedure worker, an event to execute the worker (more than one run in parallel) and procs to drop off, check on, and get the results of a SQL statement (which always waits if the SQL is not done yet). I don't know if MariaDB 5.5 or 10 adds GET DIAGNOSTICS, but it will work with any version that has it. You can comment that out and just put a generic error into the table if it isn't supported, and it will work with any version that has SIGNAL. --Justin On Wed, Feb 24, 2016 at 10:01 AM, Federico Razzoli <federico_raz(a)yahoo.it> wrote: Hi Justin!

Hi, I have tried logging in with google, with linkedin and with github. I always get a 500 error from mariadb. So this means I can't reply back to the F*CKING STUPID MAILS THAT COMES TO THIS LIST THAT REQUIRE A WEB REPLY. This has been going on years now, this stupid "have to use the web site" to reply to questions. WTF MariaDB? Seriously, WTF? This system is so broken it is laughable. --Justin

I never had the login problem described by Justin, so I tested the GitHub login just for curiosity. What happened seems to me weird: * I logged out * I logged in via GitHub for the first time. An email verification is required (why?) * I didn't verify the mail * I logged in with my email & password (no social networks) * Got this message: "The application has been authorized" So it seems that my GitHub account is now verified just because someone (me, fortunately) has logged in from my browser. Looks like a bug... Regards Federico -------------------------------------------- Lun 22/2/16, Sergei Golubchik <serg(a)mariadb.org> ha scritto: Oggetto: Re: [Maria-discuss] kb login doesn't work!

[Maria-discuss] Is there something like "best practices" to migrate from Paradox to MariaDB?
by Hugo Wau 21 Feb '16

21 Feb '16

Hello, I am new here. I will have to migrate some hundred Paradox Databases (on as many machines) to MariaDB. The best way to do so, would be something like a script. My OSs are Linux (Debian) and Win7. Is there some kind of documentation of the experience of someone, who has migrated from Paradox to MySQL/MariaDB before? (I have googled for days, but have not found such yet.) With kind regards Hugo
