Как тебе идея DevConf?
Идея отличная. Все современные языки обладают интересными
технологиями. Постараюсь посетить как можно больше не-Perl-овых
докладов. Уже распечатал расписание. "Пришлось" округлить свой
доклад и еще над одним, из той же колонки, поставить вопрос, а
так все в других секциях.
Для меня это возможность познакомиться с интересными людьми.

Recently we at Best Practical was discussing penalties
of callbacks in RT. Callbacks are proved to be very good
way to extend the web UI. We call a function from component,
function checks for registered customizations for this
particular place and calls them, so custom code can either
change arguments or inject something into result stream.

Уникальная возможность лучше познакомиться с системой

В Москве, в мае пройдет мастер-класс. Это возможности из
первых рук, от одного из разработчиков системы, получить
ответы на интересующие Вас вопросы. Участие в мастер-классе
позволит повысить свою квалификацию и успешно справляться

Как обычно это бывает, решил я маленькое изменение закомитить

изменение нужно переделать. Пока я спал, сделали бранч с
последним комитом и откатили его в транке, а первый оставили

Regular expressions is a powerful tool, but they quickly
become too long to be readable. Some people use //x modifier.
I prefer split into many smaller regular expressions, for
example:
my $re_num = qr/.../;
my $re_quoted = qr/.../;
my $re_value = qr/$re_num|$re_quoted/;
It works just fine and usually I compile them in

This post is about Perl, Mason, memory leaks and hunting them easily in
objects oriented applications based on these technologies.
It's not a secret that you can cause a memory leak by introducing a cycle
with references. It often happens in tree structures when parent holds
references on all its children and each child references its parent.

For my long going tisql project I wrote Parse::Boolean

for it and it worked pretty well.
In RT we have scrips - condition, action and a template. When something happens
with a ticket, a change checked against conditions of scrips. Only those actions
are applied for which conditions returned a true value. Pretty Ruslan U.

В Request Tracker есть много интсрументов для расширения функционала
без patch'ей, но и держать в их в одной директории с инсталяцией не
стоит. Возможно завтра вы захотите их скопировать на новый сервер или
вам нужно внести изменения и от-тестировать их предварительно.
Запакуйте ваши изменения в расширение, ведь сделать это элементарно.

For a while wanted to play with Padre. It's
IDE writen in perl programming language and at this point its main target
is perl developers. I tried it once on windows, but I don't develop on
windows. For development I use perl5.8 from MacPorts on MacOS X.
First of all you find that Padre requires threaded perl and it's reasonable
requirement. So I had to switch perl. Ruslan U. Zakirovhttp://www.blogger.com/profile/03624173032909741379noreply@blogger.com5tag:blogger.com,1999:blog-19258261.post-33508932563274637012009-07-28T00:55:00.001+04:002009-07-28T00:55:14.748+04:00Debugging perl programs/internals in gdb
When it comes to perl internals, print based debugging doesn't
work that well. Compilation and installation are too slow and
you can not place a print and quickly see output. At some point
gbd should be used. In perl world we have Devel::Peek's Dump

We use CHIMPS for smoking in Best Practical. It's modular
client server testing toolkit. One of its parts is smoking
client that works with SVN repositories.
It's really simple things, at least it was, you describe
projects in repositories, dependencies between them, start
smoker and commit to the repos without being affraid you
break backwards compatibility.
