Wimpie Nortje: Database migration libraries for PostgreSQL.

By www.darkchestnut.com
Published On :: Mon, 27 Apr 2020 00:00:00 GMT

Index of picking libraries blog series

It may be tempting at the start of a new project to create the first database tables manually, or write SQL scripts that you run manually, especially when you first have to spend a significant amount of time on sifting through all the migration libraries and then some more to get it working properly.

Going through this process did slow me down at the start of the project but I was determined to use a migration tool because hunting inexplicable bugs that only happen in production just to find out there is a definition mismatch between the production and development databases is not fun. Using such a tool also motivates you to write both the setup and teardown steps for each table while the current design is still fresh in your mind.

At first I considered a standalone migration tool because I expect them to be very good at that single task. However, learning the idiosyncrasies of a new tool and trying to make it fit seamlessly into my development workflow seemed like more trouble than it is worth.

I decided to stick with a Common Lisp library and found the following seven that work with PostgreSQL and/or Postmodern:

I quickly discounted Crane and Mito because they are ORM (Object Relational Mapper) libraries which are way more complex than a dedicated migration library. Development on Crane have stalled some time ago and I don't feel it is mature enough for frictionless use yet. Mito declares itself as being in Alpha state; also not mature enough yet.

I only stumbled onto cl-mgr and Orizuru-orm long after making my decision so I did not investigate them seriously. Orizuru-orm is in any case an ORM which I would have discounted because it is too complex for my needs. CL-mgr looks simple, which is a good thing. It is based on cl-dbi which makes it a good candidate if you foresee switching databases but even if I discovered it sooner I would have discounted it for the same reason as CL-migrations.

CL-migrations looks very promising. It is a simple library focusing only on migrations. It uses clsql to interface with the database which bothered me because I already committed to using Postmodern and I try to avoid adding a lot of unused code to my projects. The positive side is that it interfaces to many different databases so it is a good candidate if you are not committed to using Postmodern. It is also a stable code base with no outstanding bug reports.

The two projects I focused on was Postmodern-passenger-pigeon and Database-migrations because they both use Postmodern for a database interface.

Postmodern-passenger-pigeon was in active development at the time and it seemed safer to use than Database-migrations because it can do dry runs, which is a very nice feature when you are upgrading your production database and face the possibility of losing data when things go awry. Unfortunately I could not get it working within a reasonable amount of time.

I finally settled on Database-migrations. It is a small code base, focused on one task, it is mature and it uses Postmodern so it does not pull in a whole new database interface into my project. There are however some less positive issues.

The first issue is a hindrance during development. Every time the migrations ASDF system (or the file containing it, as ASDF prefers that all systems be defined in a single file) is recompiled it adds all the defined migrations to the migrations list. Though each one will only be applied once to the DB it is still bothersome. One can then clear the list with (setf database-migrations::*migrations* nil) but then only newly modified migration files will be added. The solution then is to touch the .asd file after clearing the migrations list.

The second negative point is quite dangerous. The downgrade function takes a target version as parameter, with a default target of 0. This means that if you execute downgrade without specifying a target version you delete your whole database.

I am currently using Database-migrations and it works well for me. If for some reason I need to switch I will use cl-migrations.

Using Database-migrations

To address the danger of unintentionally deleting my database I created a wrapper function that does both upgrade and downgrade, and it requires a target version number.

Another practical issue I discovered is that upgrades and downgrades happen in the same order as they are defined in the migration file. If you create two tables in a single file where table 2 depends on table 1 then you can not revert / downgrade because Database-migrations will attempt to delete table 1 before table 2. The solution here is to use the def-queries-migration macro (instead of def-query-migration) which defines multiple queries simultaneously . If you get overwhelmed by a single definition that defines multiple tables the other option is to stick with one migration definition per file.

A Maltese priest’s distorted view of the judiciary's role in society

By maltaobserver.blogspot.com
Published On :: Tue, 28 Feb 2012 08:19:00 +0000

In yesterdays The Times a Maltese priest, Mgr. Anton Gaucia, complains once more that a High Court in London a few weeks ago gave a sentence ruling that “the Catholic Church can be held liable for the wrongdoings of its priests”. Mgr. Gaucia have earlier, January 8 in Sunday Times, made the same complaint. Now Mgr. Gaucia also complains over the fact that a Mr. Justice in London has ruled that “the saying of prayers as part of the formal meeting of a council is not lawful”, adding that “there is no statutory power permitting the practice to continue”.
First things first; of course the Church shall be liable for what its employees/priests do in Alphain their capacity as priests. The children in these cases were in the care of a Catholic institution. I wonder what Mgr. Gaucia would say about if a municipal employee at a daycare sexually molest a child that the child’s parents left in its care. Of course, the municipality would be responsible for its negligence and for its failure to protect a child. The same goes of course for the Church. Mgr. Gaucia may of course, probably not being a father himself in the more down to earth sense, not understand what damage the Church and its priests done to these children. The people The Observer talked to in this matter in Malta all agree with The Observer and I think it would be wise of the Church to listen to the people in this.
Second; it might soon be time for priests like Mgr. Gauci and his colleagues to realize what century they live in. The time when Catholics ruled southern Europe is gone forever. There are Muslims, Hindus, Jews and many other people of different beliefs that have and are going to have positions in the society among which, of course, also positions in a council. Does Mgr. Gauci really mean that these people must attend Catholic or Protestant prayers? Or shall they leave when such prayer is to be said? Another possibility would of course be to have, say ten, different rooms where people of different beliefs could pray in accordance with such belief before the council meeting. Mgr Gauci, please grow up and realize what reality you live in.

Teenage births once more

By maltaobserver.blogspot.com
Published On :: Tue, 20 Mar 2012 08:49:00 +0000

In todays The Times the problem with teenage pregnancies is addressed again. In the article it is said that Angela Abela, a clinical psychologist and the director of the University’s Centre for Family Studies, not only is asking questions but also has the key which is education and early intervention. With early intervention she does not mean intervention as early as before conception; no, she means by early intervention the time when the teenager still is pregnant. In a more modern society that would be the right approach, because then it might still be time for abortion. That is, of course, not what Ms Abela had in mind. No, she wants to involve the young father. One can wonder if she really believes that a teenage father can mature in such a short time and be a responsible father. Of course he cannot. Ms Abela seems to mean that one of the keys to solve the problem is to give instructions on how best to deal with a situation where a teenager is still pregnant or have given birth. It is of course commendable, but it does not solve the problem that Malta has the highest rate of teenage mothers in the EU related to the population. The solution must be to strive to prevent teen pregnancy. This can only happen through sex education ( in which one might even strongly discourage adolescents to have sex outside marriage, this is, after all, Malta), contraception counseling, access to contraceptives and, something that is not the case for Malta in perhaps 20-30 years, free abortions. The problem with teenage mothers will persist as long as you do not introduce sex education and teaching about contraception and its use. It is as simple as that. Malta is, however, in many ways far behind the more modern EU states and the Catholic Church is in many ways responsible for this. See also The Observers article in this subject of March 14

"Three Things I Wish I Knew When I Started Designing Languages"

By lambda-the-ultimate.org
Published On :: Tue, 19 Mar 2019 00:20:53 +0000

The transcript of Three Things I Wish I Knew When I Started Designing Languages, a talk given by Peter Alvaro somewhere or other, is up at Info Q.

Peter Alavaro's main research interest is in taming distributed systems. He starts his talk with the provocative thesis, "In the future, all radical new languages will be domain-specific languages." He talks of the evolution of his ideas about dealing with distributed systems:

  1. Little interest by designers of programming-language designers in filling huge difficulty of debugging in context of distributed systems;
  2. PLs often make handling of data somewhat implicit, even with functional programming, which he says is dangerous in distributed programming;
  3. To talk about the flow of data properly, we need to talk about time;
  4. Two things that influenced him as a grad student: Jeff Ullman's claim that encapsulation and declarativity are in tension, and Fagin's theorem (the existential fragment of second-order logic characterises NP);
  5. Idea that distributed systems can be considered as protocols specified a bit like SQL or Datalog queries;
  6. Triviality with query languages of characterising the idea of place in distributive systems: they are just another relation parameter;
  7. Describing evolution of a system in time can be done with two other things: counters and negation, leading to Bertram Ludäscher's language Statelog. But this way of doing things leads to the kind of low-level overexpressive modelling he was trying to avoid;
  8. "What is it about...protocols that they seem to require negation to express?” Turns out that if you drop negation, you characterise the protocols that deliver messages deterministically.

He summarises by saying the only good reason to design a programming language (I assume he means a radically novel language) is to shape your understanding of the problem. No regrets of being the only user of his first language, Datalist, because the point is that it shaped all his later thought in his research.
