  • how to create english language dictionary application with python (django)?

    - by sintaloo
    Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.

  • Does Anyone Still Prefer N-Tier Architecture After Having *Shipped* an MVC Application?

    - by Jim G.
    Other SO threads have asked people if they prefer N-Tier or MVC architecture. I'm not looking to continue that debate on this thread. I'm looking for something more specific. My Question: Does Anyone Still Prefer N-Tier Architecture After Having Shipped an MVC Application? Reason for My Question: Before I shipped an MVC web application, I wasn't convinced that it was superior to N-Tier Architecture. Specifically, if better unit testing was the only obvious benefit of MVC, then I saw no reason to switch gears and adopt a new architecture. But after having shipped an MVC application, I can see many benefits (which have been enumerated on other threads).

  • How to download the xml file from server and use it inside application ?

    - by Praween k
    Hi Commonware, As you provided the solution .Actually my application requirement is exactly matches as you told i.e first download it from server and then display the file and it should also be updated as per the server file is updated within running period.Can u please provide me the application code for this .This will be very much helpful.I need it Urgently!!!!!!! [If it blows up, you will either need to split it into multiple files (each with a subset of your data), or not package it with the application, instead downloading it from a server on first run of your appl.] Thanks in advance.

  • How to track when my application has unexpectedly shut down?

    - by Vilx-
    I'm writing an application whose purpose involves a lot of logging of different events. Among those I would also like to have an event that the application was shut down - even if unexpectedly like because of a power loss. Naturally, when the power goes out I don't get a chance to write anything anywhere. So my idea was to continuously write a timestamp in some known location (say, once per minute), and when the application was next run, it could determine the approximate time of the unexpected shutdown. A precision of 1 minute would be acceptable for me. However I'm worried that caching at the OS and disk level might interfere with this approach. Is there a better way or if not - how to make sure that the data I just wrote is REALLY written out to the physical medium? Added: Oh, almost forgot the buzzword line: Windows XP and above; .NET 3.5; C#.

  • Need guidance for my first Android application: how many activities should I use?

    - by jul
    Hi, I'm starting Android doing an application for searching restaurants, and some guidance would be welcome! On the first screen I'd like to have a search field with a submit button (I get the data from a web service), and below a list with the results of the search. When clicking on one of the items of the list it will show a screen with the restaurant details as well as a map showing its location. My questions are: Can I do everything in one single activity or should I do an activity for the search, one for the result list, one for the restaurant description, and another for the map? Would doing one single activity make the application more responsive? How can I use a list and a map within a normal activity (without ListActivity and MapActivity)? Any help, pointer, example application or sample code is very appreciated! Thank you Jul

  • Is it possible to exclude folders from a web application project in vs 2010?

    - by JL
    I had previously asked this question. At the time I was working with VS 2008. To restate the question. I have a web application that generates 1000's of small xml files in a certain directory. I would like to exclude this directory from the web application project in visual studio 2010. With vs 2008 it was not possible. Has anything changed? Besides the general wait for VS to iterate through this directory and add an item in the solution explorer for each file, it also strains my system resources, so I would like to exclude it from the project, but the dir and files need to physically exist on disk, because they are part of the application. Any OOB VS 2010 solutions, or any good workarounds? Thanks Update: This also sums up the issue nicely http://forums.asp.net/t/1179077.aspx

  • How to access web page hierarchy inside a application.

    - by Hazior
    Trying to figure out how to programmatically access the web pages in the application. Just something simple like a list of them would be awesome. I know I can create a list but I was wondering if there was something that could 'look' at the pages and add a new one to the list if you make a new page for the application. Example with 7 pages: Error Default Login Content Users ContactUs Admin I am half awake so I may be a little unclear. Maybe puting it all in a single question will be easier. How do you autogenerate a list of all webpages in your current application?

  • How to invoke a Servlet (doGet) in a web application on startup?

    - by Dan
    I need to invoke a Servlet on application startup since it contains some application initialization logic. I know I can set load-on-startup configuration, but this will only invoke Servlet’s init method. I need to invoke a doGet method and pass some Url parameters to it. Servlet doGet method expects ServletRequest and ServletResponse objects. Also, since this is clustered application, I need to know exactly what node I am accessing (since one option is just to open a socket and invoke a Servlet). What is the best option to perform this?

  • How can I combine multiple iPhone applications in to one application?

    - by Toret
    At the moment I have 2 completed iPhone applications. Both these applications must be contained in to one application. I can't have multiple apps on the app store and to avoid confusion among people using these apps I must have them contained to a single application that gives the user the capability to launch any application in the wrapper. How can I go about doing this. Some of the ideas that crossed my mind are: Building a Framework, or building a library. But Im not even sure if I'm heading in the right direction.

  • Oracle Functional Testing Suite Advanced Pack for Oracle EBS Now Available

    - by Anne Carlson (Oracle Development)
    There’s new news about automated testing of E-Business Suite using the Oracle Application Testing Suite, a.k.a, “OATS”. E-Business Suite Development is pleased to announce the availability of the new Oracle Functional Testing Suite Advanced Pack for Oracle E-Business Suite. The new pack, available with the latest release of Oracle Application Testing Suite (12.4.0.2), provides pre-built test components and flows to automate the in-depth testing of Oracle E-Business Suite applications. Designed for use with the Oracle Application Testing Suite and its Oracle Flow Builder capability, these pre-built components and flows can help Oracle E-Business Suite customers to significantly reduce the time and effort needed to create and maintain automated test scripts. The Oracle Functional Testing Suite Advanced Pack for Oracle E-Business Suite is available now for EBS 12.1.3, and availability for EBS 12.2 is planned. Some Background on Automating Testing with Oracle Application Testing Suite and Oracle Flow Builder      Testing complex packaged applications like Oracle E-Business Suite can be time-consuming and challenging for organizations, hampering their ability to upgrade to latest releases or apply latest patches. Oracle Application Testing Suite offers organizations a unique and powerful testing platform for Oracle E-Business Suite and other Oracle applications. With the 12.3.0.1 release of Oracle Application Testing Suite, we introduced the Oracle Flow Builder testing framework and accompanying starter pack of pre-built test components and flows. The starter pack, which contains over 2000 components and 200 flows, provides broad coverage of commonly-used base functionality and is designed to jump-start the test automation effort. Using Oracle Flow Builder, even non-technical testers can create working test scripts using the pre-built components that Oracle provides. Each component represents an atomic test operation such as “create an invoice batch” or “apply an invoice hold.” Testers can assemble the pre-built components into test flows, and combine test flows with spreadsheet data to drive the testing of multiple data conditions. The Oracle Flow Builder framework allows customers to add, modify and extend the pre-built components to address new functionality and customizations of the Oracle E-Business Suite. Using Oracle Flow Builder’s component-based test generation framework instead of a traditional record/playback approach has allowed the EBS Quality Assurance team to reduce their test automation effort by 60%. E-Business Suite customers can significantly reduce their test automation effort using Oracle Application Testing Suite with Oracle Flow Builder and the pre-built test components and flows that Oracle provides. Oracle Functional Testing Suite Advanced Pack for Oracle E-Business Suite Improves Test Coverage With the Oracle Application Testing Suite 12.4.0.2 and the new Oracle Functional Testing Suite Advanced Pack for Oracle E-Business Suite, we are now delivering a significant number of additional test components and flows beyond those contained in the Oracle Flow Builder starter pack. These additional test components and flows provide 70-80% test coverage and enable the automation of detailed and complex test flows across the following Oracle E-Business Suite products: Oracle Asset Lifecycle Management Oracle Channel Revenue Management Oracle Discrete Manufacturing Oracle Incentive Compensation Oracle Lease and Finance Management Oracle Process Manufacturing Oracle Procurement Oracle Project Management Oracle Property Manager Oracle Service Downloads You can download the Oracle Functional Testing Suite Advanced Pack for Oracle E-Business Suite from the Oracle Technology Network.

  • Oracle Enterprise Manager 11g is Here!

    - by chung.wu
    We hope that you enjoyed the launch event. If you missed it, you may still watch it via our on demand webcast, which is being produced and will be posted very shortly. 11gR1 is a major release of Oracle Enterprise Manager, and as one would expect from a big release, there are many new capabilities that appeal to a broad set of audience. Before going into the laundry list of new features, let's talk about the key themes for this release to put things in perspective. First, this release is about Business Driven Application Management. The traditional paradigm of component centric systems management simply cannot satisfy the management needs of modern distributed applications, as they do not provide adequate visibility of whether these applications are truly meeting the service level expectations of the business users. Business Driven Application Management helps IT manage applications according to the needs of the business users so that valuable IT resources can be better focused to help deliver better business results. To support Business Driven Application Management, 11gR1 builds on the work that we started in 10g to provide better support for user experience management. This capability helps IT better understand how users use applications and the experience that the applications provide so that IT can take actions to help end users get their work done more effectively. In addition, this release also delivers improved business transaction management capabilities to make it faster and easier to understand and troubleshoot transaction problems that impact end user experience. Second, this release includes strengthened Integrated Application-to-Disk Management. Every component of an application environment, from the application logic to the application server, to database, host machines and storage devices, etc... can affect end user experience. After user experience improvement needs are identified, IT needs tools that can be used do deep dive diagnostics for each of the application environment component, analyze configurations and deploy changes. Enterprise Manager 11gR1 extends coverage of key application environment components to include full support for Oracle Database 11gR2, Exadata V2, and Fusion Middleware 11g. For composite and Java application management, two key pieces of technologies, JVM Diagnostic and Composite Application Monitoring and Modeler, are now fully integrated into Enterprise Manager so there is no need to install and maintain separate tools. In addition, we have delivered the first set of integration between Enterprise Manager Grid Control and Enterprise Manager Ops Center so that hardware level events can be centrally monitored via Grid Control. Finally, this release delivers Integrated Systems Management and Support for customers of Oracle technologies. Traditionally, systems management tools and tech support were separate silos. When problems occur, administrators used internally deployed tools to try to solve the problems themselves. If they couldn't fix the problems, then they would use some sort of support website to get help from the vendor's support staff. Oracle Enterprise Manager 11g integrates problem diagnostic and remediation workflow. Administrators can use Oracle Enterprise Manager's various diagnostic tools to begin the troubleshooting process. They can also use the integrated access to My Oracle Support to look up solutions and download software patches. If further help is needed, administrators can open service requests from right within Oracle Enterprise Manager and track status update. Oracle's support staff, using Enterprise Manager's configuration management capabilities, can collect important configuration information about customer environments in order to expedite problem resolution. This tight integration between Oracle Enterprise Manager and My Oracle Support helps Oracle customers achieve a Superior Ownership Experience for their Oracle products. So there you have it. This is a brief 50,000 feet overview of Oracle Enterprise Manager 11g. We know you are hungry for the details. We are going to write about it in the coming days and weeks. For those of you that absolutely can't wait to find out more, you may download our software to try it out today. In fact, for the first time ever, the initial release of Oracle Enterprise Manager is available for both 32 and 64 bit Linux. Additional O/S ports will arrive in the coming weeks. Please stay tuned on the Oracle Enterprise Manager blog for additional updates.

The SPECjEnterprise2010 benchmark has been designed and developed to cover the Java EE 5 specification's significantly expanded and simplified programming model, highlighting the major features used by developers in the industry today. This provides a real world workload driving the Application Server's implementation of the Java EE specification to its maximum potential and allowing maximum stressing of the underlying hardware and software systems. The workload consists of an end to end web based order processing domain, an RMI and Web Services driven manufacturing domain and a supply chain model utilizing document based Web Services. The application is a collection of Java classes, Java Servlets, Java Server Pages, Enterprise Java Beans, Java Persistence Entities (pojo's) and Message Driven Beans. The SPECjEnterprise2010 benchmark heavily exercises all parts of the underlying infrastructure that make up the application environment, including hardware, JVM software, database software, JDBC drivers, and the system network. The primary metric of the SPECjEnterprise2010 benchmark is jEnterprise Operations Per Second ("SPECjEnterprise2010 EjOPS"). This metric is calculated by adding the metrics of the Dealership Management Application in the Dealer Domain and the Manufacturing Application in the Manufacturing Domain. There is no price/performance metric in this benchmark. Key Points and Best Practices Sixteen Oracle WebLogic server instances were started using numactl, binding 2 instances per chip. Eight Oracle database listener processes were started, binding 2 instances per chip using taskset. Additional tuning information is in the report at http://spec.org.

  • OSI Model

    - by kaleidoscope
    The Open System Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model. A layer is a collection of conceptually similar functions that provide services to the layer above it and receives service from the layer below it. Description of OSI layers: Layer 1: Physical Layer ·         Defines the electrical and physical specifications for devices. In particular, it defines the relationship between a device and a physical medium. ·         Establishment and termination of a connection to a communications medium. ·         Participation in the process whereby the communication resources are effectively shared among multiple users. ·         Modulation or conversion between the representation of digital data in user equipment and the corresponding signals transmitted over a communications channel. Layer 2: Data Link Layer ·         Provides the functional and procedural means to transfer data between network entities. ·         Detect and possibly correct errors that may occur in the Physical Layer. The error check is performed using Frame Check Sequence (FCS). ·         Addresses is then sought to see if it needs to process the rest of the frame itself or whether to pass it on to another host. ·         The Layer is divided into two sub layers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. ·         MAC sub layer controls how a computer on the network gains access to the data and permission to transmit it. ·         LLC layer controls frame synchronization, flow control and error checking.   Layer 3: Network Layer ·         Provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks. ·         Performs network routing functions, and might also perform fragmentation and reassembly, and report delivery errors. ·         Network Layer Routers operate at this layer—sending data throughout the extended network and making the Internet possible.   Layer 4: Transport Layer ·         Provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. ·         Controls the reliability of a given link through flow control, segmentation/de-segmentation, and error control. ·         Transport Layer can keep track of the segments and retransmit those that fail. Layer 5: Session Layer ·         Controls the dialogues (connections) between computers. ·         Establishes, manages and terminates the connections between the local and remote application. ·         Provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. ·         Implemented explicitly in application environments that use remote procedure calls. Layer 6: Presentation Layer ·         Establishes a context between Application Layer entities, in which the higher-layer entities can use different syntax and semantics, as long as the presentation service understands both and the mapping between them. The presentation service data units are then encapsulated into Session Protocol data units, and moved down the stack. ·         Provides independence from differences in data representation (e.g., encryption) by translating from application to network format, and vice versa. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. It is sometimes called the syntax layer. Layer 7: Application Layer ·         This layer interacts with software applications that implement a communicating component. ·         Identifies communication partners, determines resource availability, and synchronizes communication. o       When identifying communication partners, the application layer determines the identity and availability of communication partners for an application with data to transmit. o       When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists. o       In synchronizing communication, all communication between applications requires cooperation that is managed by the application layer.

  • GlassFish v2.1 -- getting Application Client and Eclipselink to work together?

    - by Nick
    We are trying to use Eclipselink 1.1 with Glassfish v2.1. Following the instructions on: http://wiki.glassfish.java.net/Wiki.jsp?page=FaqEclipseLinkGlassFishV2 I adapted the instructions for the appclient script on linux by adding the lines: APPCPATH=$APPCPATH:$AS_INSTALL/lib/eclipselink-1.1.1.jar export APPCPATH to the appclient shell script. This however is not working. On running the application client (using Glassfish's webstart), I get the error: WARNING: "IOP00810257: (MARSHAL) Could not load class org.eclipse.persistence.indirection.IndirectList" Anyone else succeed in getting GF v 2.1 to work with eclipselink? or any ideas on what I might be doing wrong? I found this bug report: http s://glassfish.dev.java.net/issues/show_bug.cgi?id=8204 (New users can't post more than 1 link, so remove the space between 'http' and 's'.) Where Tim Quinn (tjquinn) said: App client container support for persistence is not yet in place I think this refers only to Glassfish v3, and it should be working in Glassfish v2. Is this correct? I'm working on the assumption that this will work once the ACC knows where to find the eclipselinks jar. Thanks in advance, Nick.

  • Slicing the EDG

    - by Antony Reynolds
    Different SOA Domain Configurations In this blog entry I would like to introduce three different configurations for a SOA environment.  I have omitted load balancers and OTD/OHS as they introduce a whole new round of discussion.  For each possible deployment architecture I have identified some of the advantages. Super Domain This is a single EDG style domain for everything needed for SOA/OSB.   It extends the standard EDG slightly but otherwise assumes a single “super” domain. This is basically the SOA EDG.  I have broken out JMS servers and Coherence servers to improve scalability and reduce dependencies. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if rest of domain is unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Single Administration Point (1 Admin Server) Closely follows EDG with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Drawbacks Patching is an all or nothing affair. Startup time for SOA may be slow if large number of composites deployed. Multiple Domains This extends the EDG into multiple domains, allowing separate management and update of these domains.  I see this type of configuration quite often with customers, although some don't have OWSM, others don't have separate Coherence etc. SOA & BAM are kept in the same domain as little benefit is obtained by separating them. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service. Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Startup time for SOA may be slow if large number of composites deployed. Shared Service Environment This model extends the previous multiple domain arrangement to provide a true shared service environment.This extends the previous model by allowing multiple additional SOA domains and/or other domains to take advantage of the shared services.  Only one non-shared domain is shown, but there could be multiple, allowing groups of applications to share patching independent of other application groups. Key Points Separate JMS allows those servers to be kept up separately from rest of SOA Domain, allowing JMS clients to post messages even if other domains are unavailable. JMS servers are only used to host application specific JMS destinations, SOA/OSB JMS destinations remain in relevant SOA/OSB managed servers. Separate Coherence servers allow OSB cache to be offloaded from OSB servers. Use of Coherence by other components as a shared infrastructure data grid service Coherence cluster may be managed by WLS but more likely run as a standalone Coherence cluster. Shared SOA Domain hosts Human Workflow Tasks BAM Common "utility" composites Single OSB domain provides "Enterprise Service Bus" All domains use same OWSM policy store (MDS-WSM) Benefits Follows EDG but in separate domains and with addition of application specific JMS servers and standalone Coherence servers for OSB caching and application specific caches. Coherence grid can be scaled independent of OSB/SOA. JMS queues provide for inter-application communication. Patch lifecycle of OSB/SOA/JMS are no longer lock stepped. JMS may be kept running independently of other domains allowing applications to insert messages fro later consumption by SOA/OSB. OSB may be kept running independent of other domains, allowing service virtualization to continue independent of other domains availability. All domains use same OWSM policy store (MDS-WSM). Supports large numbers of deployed composites in multiple domains. Single URL for Human Workflow end users. Single URL for BAM end users. Drawbacks Multiple domains to manage and configure. Multiple Admin servers (single view requires use of Grid Control) Multiple Admin servers/WSM clusters waste resources. Additional homes needed to enjoy benefits of separate patching. Cross domain trust needs setting up to simplify cross domain interactions. Human Workflow needs to be specially configured to point to shared services domain. Summary The alternatives in this blog allow for patching to have different impacts, depending on the model chosen.  Each organization must decide the tradeoffs for itself.  One extreme is to go for the shared services model and have one domain per SOA application.  This requires a lot of administration of the multiple domains.  The other extreme is to have a single super domain.  This makes the entire enterprise susceptible to an outage at the same time due to patching or other domain level changes.  Hopefully this blog will help your organization choose the right model for you.

  • I never really understood: what is Application Binary Interface (ABI)?

    - by claws
    I never clearly understood what is an ABI. I'm sorry for such a lengthy question. I just want to clearly understand things. Please don't point me to wiki article, If could understand it, I wouldn't be here posting such a lengthy post. This is my mindset about different interfaces: TV remote is an interface between user and TV. It is an existing entity but useless (doesn't provide any functionality) by itself. All the functionality for each of those buttons on the remote is implemented in the Television set. Interface: It is a "existing entity" layer between the functionality and consumer of that functionality. An, interface by itself is doesn't do anything. It just invokes the functionality lying behind. Now depending on who the user is there are different type of interfaces. Command Line Interface(CLI) commands are the existing entities, consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: commands consumer: user Graphical User Interface(GUI) window,buttons etc.. are the existing entities, again consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: window,buttons etc.. consumer: user Application Programming Interface(API) functions or to be more correct, interfaces (in interfaced based programming) are the existing entities, consumer here is another program not a user. and again functionality lies behind this layer. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: functions, Interfaces(array of functions). consumer: another program/application. Application Binary Interface (ABI) Here is my problem starts. functionality: ??? existing entities: ??? consumer: ??? I've wrote few softwares in different languages and provided different kind of interfaces (CLI, GUI, API) but I'm not sure, if I ever, provided any ABI. http://en.wikipedia.org/wiki/Application_binary_interface says: ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; Other ABIs standardize details such as the C++ name mangling,[2] . exception propagation,[3] and calling convention between compilers on the same platform, but do not require cross-platform compatibility. Who needs these details? Please don't say, OS. I know assembly programming. I know how linking & loading works. I know what exactly happens inside. Where did C++ name mangling come in between? I thought we are talking at the binary level. Where did languages come in between? anyway, I've downloaded the [PDF] System V Application Binary Interface Edition 4.1 (1997-03-18) to see what exactly it contains. Well, most of it didn't make any sense. Why does it contain 2 chapters (4th & 5th) which describe the ELF file format.Infact, these are the only 2 significant chapters that specification. Rest of all the chapters "Processor Specific". Anyway, I thought that it is completely different topic. Please don't say that ELF file format specs are the ABI. It doesn't qualify to be Interface according to the definition. I know, since we are talking at such low level it must be very specific. But I'm not sure how is it "Instruction Set Architecture(ISA)" specific? Where can I find MS Window's ABI? So, these are the major queries that are bugging me.

  • Apache 2.2 and FastCGI stops responding, warnings, crashes

    - by Brett
    I've seen this question posted a few times using a Google search, with no real answers. I have a multi-threaded FastCGI application running with Apache 2.2 on FreeBSD 7.2. There are a few issues with it, and I am unable to really figure out the source of the problem even after poking through a bunch of the mod_fastcgi source code. My FastCGI application gets anywhere from 2 to 15 or so hits per second, and mostly services a back-end API (the majority of web server usage is for this, and not actually serving content). Everything seems to work ok under normal conditions, but recently this problem has been becoming worse. It starts out with the FastCGI process manager apparently trying to close unneeded processes, sending them a SIGTERM signal. I catch the signal, clean up some stuff, and exit (by calling exit()) with status code 0. This process seems to result in three log messages in my httpd error log: [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" (pid 98182) termination signaled [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" (pid 98182) terminated by calling exit with status '0' [Tue Jun 01 14:03:31 2010] [warn] FastCGI: (dynamic) server "/home/program/wwwroot/domains/www.mydomain.com/cgi-bin/program.cgi" restarted (pid 98294) I am not sure why it says it is restarting the process, but in any case no core dump is ever generated so I do believe it is the FastCGI process manager doing it's thing. This makes sense because it begins to happen after the initial load increase from restarting Apache. Since it's down for a few seconds, it gets hit with a couple of hundred requests over the first few seconds it's running again (sometimes even hitting the upper limit of MAXCLIENTS in Apache), and this seems to be the process manager doing the work of spawning more processes to handle the increased load. So this all seems fine, but here is where things get weird. There are really two problems that I see. First, my multithreaded FastCGI process spawns 25 worker threads, and all seem to be used according to my internal log files (multiple processes are clearly using multiple threads to do work). However it seems that 3 or 4 FastCGI processes is not enough to handle the 5 to 15 hit per second load, even though the requests take about .02s or so to process internally. In order to be at all responsive, it seems I need 50 or more FastCGI processes, leading me to believe that FastCGI does not realize that my program is multithreaded. I've read the documentation at http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html and do not see any option pertaining to multithreaded-ness, and my internal code is more or less set up just like the examples provided by the FastCGI library. The second problem I am having is that once process termination has happened a bunch of times as above (and seemingly at random), I begin getting a lot of these messages in my error log: [Tue Jun 01 14:06:22 2010] [warn] (32)Broken pipe: FastCGI: write() to PM failed (ignore if a restart or shutdown is pending) The messages occur for about half the hits I get to the server, and it completely kills the responsiveness of my application - it seems FastCGI will look for a working "pipe" until it finds one, and fail to realize that whatever application it is trying to contact is dead. It does still work though, it's just incredibly unresponsive - sometimes taking up to 40 or so seconds to process a request. I recompiled mod_fastcgi with some extra debugging around the point of the error message, and it appears that the error happens when it tries to write() to the application. The call to write() fails with a -1 return code, and sets errno to EPIPE. I am noticing that the issue happens mostly when either a crash occurs in one of the FastCGI processes, or a bunch of them are seemingly terminated by the process manager. I haven't had any core dumps though, except for one, where the backtrace outputted by gdb is just a single call to free() at address 0x0000000000000000 with nothing else in the stack trace, so I don't really know what to make of that. I'm thinking it happens sometime after the SIGTERM signal is caught, maybe some global variable not being cleaned up properly or something.

  • How should I config Apache2.2?

    I tried to configure Apache 2.2.17 with PHP5.4 using this manual. But when I restarted my PC and went to http://localhost/phpinfo.php, I received this message: Not Found.

  • APACHE2.2/WIN2003(32-bit)/PHP: How do I configure Apache to Run Background PHP Processes on Win 2003

    - by Captain Obvious
    I have a script, testforeground.php, that kicks off a background script, testbackground.php, then returns while the background script continues to run until it's finished. Both the foreground and background scripts write to the output file correctly when I run the foreground script from the command line using php-cgi: C:\>php-cgi testforeground.php The above command starts a php-cgi.exe process, then a php-win.exe process, then closes the php-cgi.exe almost immediately, while the php-win.exe continues until it's finished. The same script runs correctly but does not have permission to write to the output file when I run it from the command line using plain php: C:\>php testforeground.php AND when I run the same script from the browser, instead of php-cgi.exe, a single cmd.exe process opens and closes almost instantly, only the foreground script writes to the output file, and it doesn't appear that the 2nd process starts: http://XXX/testforeground.php Here is the server info: OS: Win 2003 32-bit HTTP: Apache 2.2.11 PHP: 5.2.13 Loaded Modules: core mod_win32 mpm_winnt http_core mod_so mod_actions mod_alias mod_asis mod_auth_basic mod_authn_default mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_autoindex mod_cgi mod_dir mod_env mod_include mod_isapi mod_log_config mod_mime mod_negotiation mod_setenvif mod_userdir mod_php5 Here's the foreground script: <?php ini_set("display_errors",1); error_reporting(E_ALL); echo "<pre>loading page</pre>"; function run_background_process() { file_put_contents("0testprocesses.txt","foreground start time = " . time() . "\n"); echo "<pre> foreground start time = " . time() . "</pre>"; $command = "start /B \"{$_SERVER['CMS_PHP_HOMEPATH']}\php-cgi.exe\" {$_SERVER['CMS_HOMEPATH']}/testbackground.php"; $rp = popen($command, 'r'); if(isset($rp)) { pclose($rp); } echo "<pre> foreground end time = " . time() . "</pre>"; file_put_contents("0testprocesses.txt","foreground end time = " . time() . "\n", FILE_APPEND); return true; } echo "<pre>calling run_background_process</pre>"; $output = run_background_process(); echo "<pre>output = $output</pre>"; echo "<pre>end of page</pre>"; ?> And the background script: <?php $start = "background start time = " . time() . "\n"; file_put_contents("0testprocesses.txt",$start, FILE_APPEND); sleep(10); $end = "background end time = " . time() . "\n"; file_put_contents("0testprocesses.txt", $end, FILE_APPEND); ?> I've confirmed that the above scripts work correctly using Apache 2.2.3 on Linux. I'm sure I just need to change some Apache and/or PHP config settings, but I'm not sure which ones. I've been muddling over this for too long already, so any help would be appreciated.
