php doctrine last identifier issue

- by mike

I'm running in to the issue below when trying to run the following: $store = new Store(); $store->url =$this->form_validation->set_value('website'); $store->save(); $store_id = $store->identifier(); Fatal error: Uncaught exception 'Doctrine_Connection_Exception' with message 'Couldn't get last insert identifier.' in /home/yummm/public_html/system/application/plugins/doctrine/lib/Doctrine/Connection/UnitOfWork.php:932 Stack trace: #0 /home/yummm/public_html/system/application/plugins/doctrine/lib/Doctrine/Connection/UnitOfWork.php(632): Doctrine_Connection_UnitOfWork->_assignIdentifier(Object(Category_store_assn)) #1 /home/yummm/public_html/system/application/plugins/doctrine/lib/Doctrine/Connection/UnitOfWork.php(562): Doctrine_Connection_UnitOfWork->processSingleInsert(Object(Category_store_assn)) #2 /home/yummm/public_html/system/application/plugins/doctrine/lib/Doctrine/Connection/UnitOfWork.php(81): Doctrine_Connection_UnitOfWork->insert(Object(Category_store_assn)) #3 /home/yummm/public_html/system/application/plugins/doctrine/lib/Doctrine/Record.php(1691): Doctrine_Connection_UnitOfWork->saveGraph(Object(Category_store_assn)) #4 /home/yummm/public_html/system/application/controllers/auth.php(375): Doctrine_Reco in /home/yummm/public_html/system/application/plugins/doctrine/lib/Doctrine/Connection/UnitOfWork.php on line 932 When I echo $store_id, it seems to be grabbing the last id without any issues. Any idea why this error keeps coming up even though the ID is passing correctly?

PHP 5.3.8 startup warning

Emacs: selective c-auto-newline

- by Yktula

When c-auto-newline is set to non-nil, it re-indents the current line and inserts a carriage return and then indents the new line. However. I'm using 1TBS indent-style, which means if/else statements are made like this: if (n == 1) { exit(EXIT_SUCCESS); } else { perror("n"); } Also, I write do/while write loops like this: do { printf("%d\n", n++); } while (n < 64); As such, while I do want a newline automatically inserted after every opening brace and semicolon, I don't want newlines to be automatically inserted after an if statement or do loop is concluded with a closing brace. How can I have GNU Emacs (23.2.1, *nix) selectively insert newlines like that? Along the same lines, can I have Emacs insert an opening brace, a newline, and a closing brace on another newline, while putting the cursor in the middle of the two braces after closing parentheses following an if statement, function declaration, and the like?

NetBeans behaves differently if project is run via "Run Project" or build.xml>run

- by Rogach

I slightly modified the build-impl.xml file of my NetBeans project. (Specifically, I made it to insert build time into program code). If I run project via build.xml "run" target, I get behavior I expect - the program displays build time and date. But if I run project using standard (and most obvious, used it always) button "Run Main Project", I get totally another result (no build date). Moreover, if I insert any code into build.xml, I still get result if I run the target explicitly and no result if it is run simply by NetBeans. And this leads me to conclusion, that this button uses another method to run my application. My question is: what does that button do? What method does it call? And can it be configured to run the needed target of make file?

Fluid CSS: floating column with max-width and overflow

- by Ates Goral

I'm using a fluid layout in the new theme that I'm working on for my blog. I often blog about code and include <pre> blocks within the posts. The float: left column for the content area has a max-width so that the column stops at a certain maximum width and can also be shrunk: +----------+ +------+ | text | | text | | | | | | | | | | | | | | | | | | | | | +----------+ +------+ max shrunk What I want is for the <pre> elements to be wider than the text column so that I can fit 80-character-wrapped code without horizontal scroll bars. But I want the <pre> elements to overflow from the content area, without affecting its fluidity: +----------+ +------+ | text | | text | | | | | +----------+--+ +------+------+ | code | | code | +----------+--+ +------+------+ | | | | +----------+ +------+ max shrunk But, max-width stops being fluid once I insert the overhanging <pre> in there: the width of the column remains at the specified max-width even when I shrink the browser beyond that width. I've reproduced the issue with this bare-minimum scenario: <div style="float: left; max-width: 460px; border: 1px solid red"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit</p> <pre style="max-width: 700px; border: 1px solid blue"> function foo() { // Lorem ipsum dolor sit amet, consectetur adipisicing elit } </pre> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit</p> </div> I noticed that doing either of the following brings back the fluidity: Remove the <pre> (doh...) Remove the float: left The workaround I'm currently using is to insert the <pre> elements into "breaks" in the post column, so that the widths of the post segments and the <pre> segments are managed mutually exclusively: +----------+ +------+ | text | | text | +----------+ +------+ +-------------+ +-------------+ | code | | code | +-------------+ +-------------+ +----------+ +------+ +----------+ +------+ max shrunk But this forces me to insert additional closing and opening <div> elements into the post markup which I'd rather keep semantically pristine. Admittedly, I don't have a full grasp of how the box model works with floats with overflowing content, so I don't understand why the combination of float: left on the container and the <pre> inside it cripple the max-width of the container. I'm observing the same problem on Firefox/Chrome/Safari/Opera. IE6 (the crazy one) seems happy all the time. This also doesn't seem dependent on quirks/standards mode. Update I've done further testing to observe that max-width seems to get ignored when the element has a float: left. I glanced at the W3C box model chapter but couldn't immediately see an explicit mention of this behaviour. Any pointers?

Crystal Reports Server - Database Login Needs to go Away

- by Trey Sargent

The environment I'm working in is a Crystal Reports Server 2008 talking to a MySQL Server 5.1 database using JDBC. The problem is that I get a database logon screen every time I try to access a report from Crystal Reports Server. I've setup a JDBC connection using the MySQL Connector/J driver. When I create a .rpt file I provide the login credentails all is fine. I then publish to InfoView and go to access the report and it prompts me for username and password to the database. I then went to CMC and right-clicked on the report and opened the Database Configuration. I've selected 'Use original database logon information from the report' and 'Use same database logon as when report is run'. However, I still get the logon screen when I try to access the report.

pros and cons with server management gui tools to manage linux web servers

- by ajsie

i have stumbled upon these GUI tools that could help you manage your linux server through a web interface. ebox, webmin, ispconfig, zivios, ispcp, plesk, cpanel etc. i wonder what the pros and cons are with these solutions. a lot of people is saying that they are not as good as using pure command line (ssh) to manage your server. but i think thats yet another "linux are for advanced users" talk. i agree that some things may only be done with the command line by editing directly in the configuration files. but i don't really want to do that every time and for everything. its like not having phpmyadmin for managing mysql. it would be a pain in the ass right? so if one wants to throw up a web server serving a php site oneself developed and wants all the usual stuff up and running (mysql, phpmyadmin, svn, webdav etc) is these tools the right way to go?

document.write issue

- by Dhana

I inherited a piece of code that uses document.write to insert a certain div when the code is encountered. Unfortunately, this code is causing issues in IE where the code fails. Is there a way around this to insert a div on the page without it? I can't make a big change since this code is currently used by many clients(it's like google adsense kind of thing). Is there an alternative to document.write - I don't have a way to capture a div on the page since it's something plugged in by anyone.

Convert SQLITE SQL dump file to POSTGRESQL

- by DevX

I've been doing development using SQLITE database with production in POSTGRESQL. I just updated my local database with a huge amount of data and need to transfer a specific table to the production database. SQLITE outputs a table dump in the following format: BEGIN TRANSACTION; CREATE TABLE "courses_school" ("id" integer PRIMARY KEY, "department_count" integer NOT NULL DEFAULT 0, "the_id" integer UNIQUE, "school_name" varchar(150), "slug" varchar(50)); INSERT INTO "courses_school" VALUES(1,168,213,'TEST Name A',NULL); INSERT INTO "courses_school" VALUES(2,0,656,'TEST Name B',NULL); .... COMMIT; How do I convert the above into a POSTGRESQL compatible dump file that I can import into my production server?

Occasional Deadlock.

- by Carl Robinson

Im having trouble with a web application that will deadlock occasionally There are 3 queries involved. 2 are trying to update a table UPDATE AttendanceRoll SET ErrorFlag = 0 WHERE ContractID = @ContractID AND DATEPART(month,AttendanceDate) = DATEPART(month,@Month_Beginning) AND DATEPART(year,AttendanceDate) = DATEPART(year,@Month_Beginning) and one is trying to insert into the table INSERT INTO AttendanceRoll (AttendanceDate, ContractID, PersonID, StartTime, EndTime, Hours, AbsenceReason, UpdateCount, SplitShiftID, ModifiedBy, ModifiedDate) SELECT @P33, @P34, @P35, CONVERT(datetime,REPLACE( @P36 ,'.',':')), CONVERT(datetime,REPLACE( @P37 ,'.',':')), @P38, @P39, @P40, 1, @P41, GETDATE() The deadlock graph shows a kind of circular arangement of page locks and an exchange event and the 2 update queries have the same server process id. If anyone has any ideas about how I should go about solving this issue it would be most appreciated. I have the deadlock graph that I can post if anybody needs to see it. Thanks Carl R

Clicking DetailsView’s Update button doesn’t cause a postback

If I define the following template inside DetailsView, then upon clicking an Update or Insert button, the page is posted back to the server: <EditItemTemplate> <asp:TextBox ID="txtDate" runat="server" Text='<%# Bind("Date") %>'></asp:TextBox> <asp:CompareValidator ID="valDateType" runat="server" ControlToValidate="txtDate" Type="Date" Operator="DataTypeCheck" Display="Dynamic" >*</asp:CompareValidator> </EditItemTemplate> But if I remove CompareValidator control from the above code, then for some reason clicking an Update or Insert button doesn’t cause a postback...instead nothing happens: <EditItemTemplate> <asp:TextBox ID="txtDate" runat="server" Text='<%# Bind("Date") %>'></asp:TextBox> </EditItemTemplate> Any idea why page doesn't get posted back? thanx

windows 2008 task scheduled batch file runs forever

- by phill

I currently have the following batch running in windows 2008 task scheduler. mysql --user=bobdb --password=letmein --force --named-commands --local-infile=1 --execute="insert into bobdb.attendees (name) values ('bob');insert into bobdb.attendees (name) values ('rick');" It executes nicely when I run it from a command prompt and it executes when I force it to run and it executes when it is scheduled to run. My issue is when it does run, the task scheduler seems to keep it running until it hits a timeout. Is there a command to tell it when it is finished running in the batch file so it doesn't throw a timeout error? thanks in advance

Are there any B-tree programs or sites that show visually how a B-tree works

- by Phenom

I found this website that lets you insert and delete items from a B-tree and shows you visually what the B-tree looks like: java b-tree I'm looking for another website or program similar to this. This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets you specify B-trees with an even number of elements. Also, if possible, I'd like to be able to insert letters instead of numbers. I think I actually found a different site but that was a while ago and can't find it anymore.

safely lock a file then move? windows

- by acidzombie24

I have a file and need to ensure it exist before inserting a row into the db. After i insert i need to use the PK as part of the filename and move it into another location. How do i check if it exist then lock it so it cant be deleted until i can insert into the db then proceed to move the file without it being deleted upon releasing the lock? also the file may be in use. I am thinking of copying the file into a safe location then moving that file away. In this case i need to copy a file that is being used for reading. How can i do the above steps safely? Using .NET

use of EntityManagerFactory causing duplicate primary key exceptions

- by bradd

Hey guys, my goal is create an EntityManager using properties dependent on which database is in use. I've seen something like this done in all my Google searches(I made the code more basic for the purpose of this question): @PersistenceUnit private EntityManagerFactory emf; private EntityManager em; private Properties props; @PostConstruct public void createEntityManager(){ //if oracle set oracle properties else set postgres properties emf = Persistence.createEntityManagerFactory("app-x"); em = emf.createEntityManager(props); } This works and I can load Oracle or Postgres properties successfully and I can Select from either database. HOWEVER, I am running into issues when doing INSERT statements. Whenever an INSERT is done I get a duplicate primary key exception.. every time! Can anyone shed some light on why this may be happening? Thanks -Brad

What does transaction.commit() do when the flushmode is set manual in Hibernate?

- by wei

Here is a block of code in the Java Persistence with Hibernate book by Christian and Gavin, Session session = getSessionFactory().openSession(); session.setFlushMode(FlushMode.MANUAL); // First step in the conversation session.beginTransaction(); Item item = (Item) session.get(Item.class, new Long(123) ); session.getTransaction().commit(); // Second step in the conversation session.beginTransaction(); Item newItem = new Item(); Long newId = (Long) session.save(newItem); // Triggers INSERT! session.getTransaction().commit(); // Roll back the conversation! session.close();//enter code here I am confused that why the first step and second step need to be wrapped into two separate transactions? Since the flushmode is set manual here, no operations (suppose we ignore the insert here) will hit the database anyway. So why bother with transactions here? thanks

Server Security

I want to run my own root server (directly accessible from the web without a hardware firewall) with debian lenny, apache2, php5, mysql, postfix MTA, sftp (based on ssh) and maybe dns server. What measures/software would you recomend, and why, to secure this server down and minimalize the attack vector? Webapplications aside ... This is what I have so far: iptables (for gen. packet filtering) fail2ban (brute force attack defense) ssh (chang default, port disable root access) modsecurity - is really clumsy and a pain (any alternative here?) ?Sudo why should I use it? what is the advantage to normal user handling thinking about greensql for mysql www.greensql.net is tripwire worth looking at? snort? What am I missing? What is hot and what is not? Best practices? I like "KISS" - Keep it simple secure, I know it would be nice! Thanks in advance ...

Drop on NSTableView Behavior

- by dave-gennel

Hi, I have an NSTableView and I have successfully implemented both tableView:validateDrop:proposedRow:proposedDropOperation: and tableView:acceptDrop:row:dropOperation:. I don't need tableView:writeRowsWithIndexes:toPasteboard: because that's for dragging objects out of the NSTableView. Now, the problem is that I want it to behave kind of iTunes-like. In iTunes 9.x (I don't remember it for the previous versions) you have an NSTableView (the playlist) and when you drag a file over it you get this blue focus inside the NSTableView (maybe it's the NSScrollView?) and you don't have the blue horizontal line that indicates where you're going to insert an object. So basically I would like: No blue horizontal insert line between rows when hovering a file over the NSTableView. The blue focus inside the NSTableView (or NSScrollView). Any help would be greatly appreciated so thank you in advance.

Finding all the shortest paths between two nodes in unweighted directed graphs using BFS algorithm

- by andra-isan

Hi All, I am working on a problem that I need to find all the shortest path between two nodes in a given directed unweighted graph. I have used BFS algorithm to do the job, but unfortunately I can only print one shortest path not all of them, for example if they are 4 paths having lenght 3, my algorithm only prints the first one but I would like it to print all the four shortest paths. I was wondering in the following code, how should I change it so that all the shortest paths between two nodes could be printed out? class graphNode{ public: int id; string name; bool status; double weight;}; map<int, map<int,graphNode>* > graph; int Graph::BFS(graphNode &v, graphNode &w){ queue <int> q; map <int, int> map1; // this is to check if the node has been visited or not. std::string str= ""; map<int,int> inQ; // just to check that we do not insert the same iterm twice in the queue map <int, map<int, graphNode>* >::iterator pos; pos = graph.find(v.id); if(pos == graph.end()) { cout << v.id << " does not exists in the graph " <<endl; return 1; } int parents[graph.size()+1]; // this vector keeps track of the parents for the node parents[v.id] = -1; // there is a direct path between these two words, simply print that path as the shortest path if (findDirectEdge(v.id,w.id) == 1 ){ cout << " Shortest Path: " << v.id << " -> " << w.id << endl; return 1; } //if else{ int gn; map <int, map<int, graphNode>* >::iterator pos; q.push(v.id); inQ.insert(make_pair(v.id, v.id)); while (!q.empty()){ gn = q.front(); q.pop(); map<int, int>::iterator it; cout << " Popping: " << gn <<endl; map1.insert(make_pair(gn,gn)); //backtracing to print all the nodes if gn is the same as our target node such as w.id if (gn == w.id){ int current = w.id; cout << current << " - > "; while (current!=v.id){ current = parents[current]; cout << current << " -> "; } cout <<endl; } if ((pos = graph.find(gn)) == graph.end()) { cout << " pos is empty " <<endl; continue; } map<int, graphNode>* pn = pos->second; map<int, graphNode>::iterator p = pn->begin(); while(p != pn->end()) { map<int, int>::iterator it; //map1 keeps track of the visited nodes it = map1.find(p->first); graphNode gn1= p->second; if (it== map1.end()) { map<int, int>::iterator it1; //if the node already exits in the inQ, we do not insert it twice it1 = inQ.find(p->first); if (it1== inQ.end()){ parents[p->first] = gn; cout << " inserting " << p->first << " into the queue " <<endl; q.push(p->first); // add it to the queue } //if } //if p++; } //while } //while } I do appreciate all your great help Thanks, Andra

PHP regex to match sentences that contain a year

- by zen

I need a regular expression that will extract sentences from text that contain a year in them. Example text: Next, in 1988 the Bradys were back again for a holiday celebration, "A Very Brady Christmas". Susan Olsen (Cindy) would be missing from this reunion, Jennifer Runyon took her place. This was a two hour movie in which the Bradys got together to celebrate Christmas, introducing the world to the spouses and children of the Brady kids. This movie was the highest rated TV-movie of 1988. If the example text was variable $string, I need it to return: $sentenceWithYear[0] = Next, in 1988 the Bradys were back again for a holiday celebration, "A Very Brady Christmas". $sentenceWithYear[1] = This movie was the highest rated TV-movie of 1988. If it's possible to retain the year via regex, I'd use the year within the sentence and eventually insert the sentences into a database like: INSERT INTO table_name (year, sentence) VALUES ('$year', '$sentenceWithYear[x]')
