«Flexible» protocol buffer implementation.

slookin — Sat, 25 Jun 2011 10:08:45 +0000

Every body knows about protobuf from Google team. It is very useful and effective protocol for data exchanges.

«Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal RPC protocols and file formats.»

For my project I need to implement specific router for messages from different clients. So my router (receiver) should be able to read (parse) body of message in order to get information about for routing. But I couldn’t predict all protobuf message format on design phase, as result I should analyze message format on runtime.

Google team suggest to use special technique «Self-describing Messages» : insert additional field to message with full protocol description. As result all messages will have information about their structue. It is good trick, but the message size will extremely big. (main advantage of protobuf in my project is small message size). So I decide to have full message format catalogue on my router and update this catalogue in runtime.

The plain-text .proto file should be prepared as message using descriptor.proto and protoc utility.

The code below shows how router will read protocol format from file system and parse incoming message.

We will use addressbook.proto from examples:

package tutorial;
option java_package = "com.example.tutorial";
option
java_outer_classname = "AddressBookProtos";
message Person {
  required string name = 1;
  required int32 id = 2;        // Unique ID number for this person.
  optional string email = 3;
  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;
}
  message PhoneNumber {
    required string number = 1;
    optional PhoneType type = 2 [default = HOME];
  }
  repeated PhoneNumber phone = 4;
}
// Our address book file is just one of these.
message AddressBook {
  repeated Person person = 1;
}

Clients (sender) can implement classical way for producing message (generate java classes via protoc):

protoc –java_out=. addressbook.proto

And following example of message generate:

   Person.Builder person = Person.newBuilder();
   person.setId(Integer.valueOf(42));
   person.setEmail("test_email@gmail.com");
   person.setName("Viktor Villari");
   Person p = person.build();
   FileOutputStream fstream = new FileOutputStream(messagePath);
   CodedOutputStream outSream = CodedOutputStream.newInstance(fstream);
   p.writeTo(outSream);
   outSream.flush();

as result we will have file with message (messagePath)

After it we should generate descriptor for our addressbook.proto:

protoc --descriptor_set_out=address.proto.descriptor  addressbook.proto

I transfer address.proto.descriptor to receiver format catalogue and following code allow me to parse message:

   // read protocol Descriptor
   FileInputStream input = new FileInputStream(protoDescripter);
   DescriptorProtos.FileDescriptorSet fdsProto = DescriptorProtos.FileDescriptorSet.parseFrom(input);
// point to specific file in FileDescriptorSet
   System.out.println("File name = " + fdsProto.getFile(0).getName());
   FileDescriptor fileDescr = FileDescriptor.buildFrom(fdsProto.getFile(0), new FileDescriptor[0]);
// point to specific message type in FileDescriptor
   System.out.println("Message type = " + fileDescr.getMessageTypes().get(0).getName());
   Descriptor messageType=fileDescr.getMessageTypes().get(0);
// read and parse incomming message
   input = new FileInputStream(messagePath);
   DynamicMessage dm = DynamicMessage.parseFrom(messageType, input);
// output fields from message
   Iterator i = messageType.getFields().iterator();
while (i.hasNext()) {
    FieldDescriptor field = i.next();
    System.out.println(messageType.getName() + "." + field.getName() + " value="
      + dm.getField(field) + " type=" + field.getJavaType());
   }
So, output of code:
File name = addressbook.proto
Message type = Person
Person.name value=Viktor Villari type=STRING
Person.id value=42 type=INT
Person.email value=test_email@gmail.com type=STRING
Person.phone value= type=MESSAGE

Resume: using this technique you able to build dynamic message parsing without increase size of each message.

Statistics from RequisitePro via RPX

slookin — Sun, 07 Nov 2010 21:34:15 +0000

I’m spent this long weekend for study RXP protocol which IBM recommend to communicate with IBM Rational RequisitePro.

As I know java, I decide to write small utility on Java RPX. I was my mistake, because IBM Java RPX is worst API which I sow in last years. Methods like OpenProject(arg0, arg1, arg2, arg3, arg4, arg5) make me crazy.

As result I use VBA RPX API as reference and Java RPX API just as implementation.

In any case, result of my homework – I’m able to build statistics based on RequisirePro repository about how often I change requirements in project. It helps me to analyse time when my requirements set is stable and ready for implementation. Also this simple chart show me which external actions affect requirements (architecture overview stage, review requirements by development team or test team).

In my next step I going to implement RSS stream for all requirements changes in project scope, it should help my team follow in any changes in product in frame iterative process.

Prestashop: Изменения в базовых модулях

slookin — Tue, 15 Jun 2010 20:00:34 +0000

Для одного из сайтов понадобилось перенести несколько модулей из правой колонки в левую. (в частности blockcart – корзину покупателя)

В базовом функционале модули этого не делали.

Исправить просто, надо добавить регистрацию модуля для нового (левого) «хука» и переустановить модуль.

$this->registerHook('rightColumn')

Для двух модулей (корзина, и модуль скидок), я эти изменения сделал – можно скачать здесь.

blockcart.zip
blockspecials.zip

PS базировался на последней на данный момент версии prestashop 1.3.1

Поддержка товаров с ценой «по запросу». prestashop.

slookin — Sun, 11 Apr 2010 09:35:36 +0000

В магазине wo-da.ru появилась необходимость корректно отображать товары, цена на которые не известна на данный момент, и требует согласования по телефону. (Это особенность дистрибьютерского бизнеса для дорогих артикулов).

Дабы минимизировать изменения в коде prestashop было решено:

1) для товаров цена накоторые неизвестна ставить цену 0 (у нас нет бесплатных товаров, поэтому нету и конфликтов)

2) для тех товаров у которых цена 0 – в шаблонах сделать допольнительную обработку и не отображать цену и кнопку «добавить в корзину».

измененные файлы:

Cache module : Prestashop

slookin — Mon, 28 Dec 2009 20:56:59 +0000

In order to improve site performance I implement Cache module for my shop, which based on prestashop.
Cache module based on Pear:Cache_Lite engine and able to store cached part of pages to file system.
My estimation in such performance improvement – 2-8 times, depends of you site and database.

Also for support cache module I implement «preaching sub module» it run every night and prepare caches which will be used during day.

UPDATE (13 Jan 2010)

Google performance overview

On average, pages in your site take 1.7 seconds to load (updated on Jan 4, 2010). This is faster than 74% of sites. These estimates are of low accuracy (less than 100 data points). The chart below shows how your site’s average page load time has changed over the last few months. For your reference, it also shows the 20th percentile value across all sites, separating slow and fast load times.

WWW.WO-DA.RU магазин сантехники

slookin — Wed, 25 Nov 2009 14:10:39 +0000

2009-й год будет также памятен для меня открытием еще одного интернет магазина – WWW.WO-DA.RU.

Магазин сантехники WO-DA.RU работает в Санкт-Петербурге и Ленинградской области и предлагает по конкурентным ценам широкий ассортимент:

для ванных комнат (ванные, смесители, душевые)
для кухонь (мойки, измельчители отходов)
а также теплые полы и водонагреватели

Помятуя опыт работы на www.oscommerce.org (см. топик о магазину Woodyshop) было принято решение в этот раз базироваться на продукте Prestashop. Если быть кратким, то Prestashop предоставляет кучу полезных модулей сразу встроенных в продукт. При этом он построен на более прозрачной и понятной архитектуре (по сравнение с oscommerce) – почти чистый MVC, классический шаблонизатор – Smarty, продуманный функционал сайта по умолчанию в поставке – и прочие прелести.

Перечислю основные модули/фичи которые я использую:

1. SEO – включает в себя:

URL – человеко-понятные ссылки.
Cannonical meta tag
Header meta tags – для ключевых слов и описания

2. Product Attributes – атрибуты товаров, цена для разных атрибутов, наличие на складе.

3. PDF invoce – документы формируются в PDF

4. Ajax basket – красиво, динамично.

5. Google Analytics – статистика на google analytic.

6. Smarty template engine – удобный и простой движок для шаблонов сайта. Кстати верстка в схеме по умолчанию – XHTML и основана на div.

далее уже фичи которые есть в любых движках магазинов

8. WYSIWYG редактор

9. Категории/подкатегории/товары

10. Автоматическое изменение размеров изображений

11. Небольшая встроеная CMS

самому пришлось разработать

12. Модуль кеширования

«Flexible» protocol buffer implementation.
