I have gone through number of threads on stackoverflow and on other forums to find the answer but could not find relevant answer. People have applied different approaches but none has worked for me thus far.
I am using CI 3 on XAMPP and whenever I load database library in the model, I run into 500 Error.
Here is my CI database config info:
'hostname' => 'localhost',
'username' => 'my_user',
'password' => 'my_pass',
'database' => 'prod_db',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
PHP ini db libraries are as below:
extension=php_bz2.dll
extension=php_curl.dll
extension=php_fileinfo.dll
;extension=php_ftp.dll
extension=php_gd2.dll
extension=php_gettext.dll
;extension=php_gmp.dll
;extension=php_intl.dll
;extension=php_imap.dll
;extension=php_interbase.dll
;extension=php_ldap.dll
extension=php_mbstring.dll
extension=php_exif.dll ; Must be after mbstring as it depends on it
extension=php_mysqli.dll
;extension=php_oci8_12c.dll ; Use with Oracle Database 12c Instant Client
;extension=php_openssl.dll
;extension=php_pdo_firebird.dll
extension=php_pdo_mysql.dll
;extension=php_pdo_oci.dll
;extension=php_pdo_odbc.dll
;extension=php_pdo_pgsql.dll
extension=php_pdo_sqlite.dll
;extension=php_pgsql.dll
;extension=php_shmop.dll
; The MIBS data available in the PHP distribution must be installed.
; See http://www.php.net/manual/en/snmp.installation.php
;extension=php_snmp.dll
My model code is as below:
class loginmodel extends CI_Model {
public function validate_login($username, $password) {
$this->load->database();
$var = 0;
return $var;
}
}
Whenever I remove $this->load->database(); from the model, my code runs and i am able to redirect to a "Login Failed" page. BUT, whenever I load my database library in autoload.php or load it in above model, code fails.
Autoload.php
$autoload['libraries'] = array('database');
Apache error logs showed below errors but I could not figure as why this was happening.
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\php\\ext\\php_mysqli.dll' - The specified module could not be found.\r\n in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\php\\ext\\php_pdo_mysql.dll' - The specified module could not be found.\r\n in Unknown on line 0
Please advise.
EDIT:
I verified all config to be OK and as stated in the comments, I added environment variables to windows and verified through PHPInfo that mysqli and mysqlnd were loaded.
Despite getting all the config right, error still persisted and I did a clean install of CI to reproduce library load failure. This time CI returned an error that db access was denied.
I then realized that after migration, database user was not created in the new environment. So once I created the desired user and assigned it required privileges, I was able to run the code just fine.
Therefore, if anyone encounters such issue in future, below steps might help:
First and foremost, verify if your desired user can access the
database.
Modify your .htaccess to use your desired URL schemes only after
verifying that database connection is working
Then verify that absolute path is available in PHP.ini on XAMPP.
Plus, verify that PHP is added in the environment variables. My
Values on Windows 10 are as follows: Variable Name: PHP , Variable
Value: C:\xampp\php\ext
In CI, mysqli is selected as database driver
In PHP.ini mysqli extension is enabled. i.e. php_mysqli.dll
Echo PHPInfo to verify that mysqli and mysqlnd are available in your
installation.
If nothing works, do a clean install of CI on a separate directory and load database library after setting up your database configuration and before setting up .htaccess until you can reproduce the error.
Hope that error will be eliminated!
I am using neo4j enterprise 3.0.3 version for windows. Following the operations manual 3.0, I have installed the neo4j service with bin\neo4j install-service. But I can't start it with bin\neo4j start. It said
Invoke-Neo4j : Failed to start service 'Neo4j Graph Database - neo4j (neo4j)'.
And I can't start the neo4j service in windows serice either. Maybe anyone have encountered this case before?
I had the same problem: I am using neo4j community 3.1.2 for windows and installed the service with the neo4j.bat file without any problems.Then i wanted to start the service with neo4j.bat and got the same error as you
I found a solution that worked for me. My neo4j files were in a folder, where the path to the folder contained spaces (C:\Program Files\Neo4j) Then i moved the folder one level up (C:\Neo4j).
After that i could start the service without problems.
Maybe this solution helps.
I am running neo4j on windows and in my case the crux of the issue was that there was an incompatibility between the installed versions of Java (32-bit) v/s OS version. The biggest clue that led me to this is the following set of lines in neo4j-service.2018-08-03 log file
[2018-08-03 14:55:42] [info] [ 1432] Starting service...
[2018-08-03 14:55:42] [error] [ 1432] %1 is not a valid Win32 application.
[2018-08-03 14:55:42] [error] [ 1432] Failed creating java C:\JavaNew\bin\server\jvm.dll
[2018-08-03 14:55:42] [error] [ 1432] %1 is not a valid Win32 application.
[2018-08-03 14:55:42] [error] [ 1432] ServiceStart returned 1
There are a fair number of potential issues, and I have made an attempt to compile all the issues with this,
Windows services cannot deal with service names in folders that have spaces; especially if there is another folder with the same name as the one with spaces.
For example - C:\Program Files... will have issues if C:\Program\Something...
To work around this, I put Neo4j in root folder c:\Neo4j
Get-Java.ps1 (under ..\bin\Neo4j-Management folder)looks in the path variable for 'JAVA_HOME' (usually found in *nix environments). If it does not find it here, it keeps looking in registry, and finally throws up its hand!
To deal with this, I simply put in a path variable. For a good measure, I uninstalled Java and re-installed Java in the root folder under C:\JavaNew
In retrospect, this step is probably not on part of the problem, and hence can be ignored. But I am leaving it here for completeness sake.
Invoke-Neo4j.ps1 (also under ..\bin\Neo4j-Management folder) has code that determines if the OS is 32-bit (or 64-bit). Based on this it determines if it should run prunsrv-i386.exe (32-bit) or prunsrv-amd64.exe (64-bit).
This has to match the Java version installed.
Upon running java -XshowSettings:all, and inspecting the sun.arch.data.model value (32, in my case), I realized that my OS is 64 bit and the Java version is 32-bit.
To deal with this, I put in code (very klugey!). I am sure there are much better ways to get to the same outcome, but this is what I used.
switch ( (Get-WMIObject -Class Win32_Processor | Select-Object -First 1).Addresswidth ) {
32 { $PrunSrvName = 'prunsrv-i386.exe' } # 4 Bytes = 32bit
#64 { $PrunSrvName = 'prunsrv-amd64.exe' } # 8 Bytes = 64bit COMMENTED as a workaround!!!
64 { $PrunSrvName = 'prunsrv-i386.exe' } # 8 Bytes = 64bit
Now, uninstall the neo4j service, install it, and start the service.
Hope this works for you.
neo4j console
Posting for latest versions > 4.x
I had the same issue using neo4j start, Neo4j console is the right command I was looking for. It is a web-based graph that acts as an interactive tutorial.
i had the same problem , after the neo4j worked for few weeks it stoop working (without any change that i made)
i have set java_home uninstall and install and now it works
neo4j-enterprise-3.3.4
I was also having weired issue as there was no error but neo4J service did not start.
[xx#ss1 bin]$ ./neo4j console
[xx#ss1 bin]$ .
The problem was with the permission on Java directory and I tried
chmod -R 777 jdk_directory
and problem got solved.
#neo4j #neo4jnotstarting
I have added a customized module named mod_confirm_delivery in ejabberd which has compiled and added successfully but when i am sending a message an error is coming in my ejabberd error log file, That is:
2016-03-15 17:03:38.306 [error] <0.2653.0>#ejabberd_hooks:run_fold1:368 {undef,[{mod_confirm_delivery,send_packet,[{xmlel,<<"iq">>,[{<<"xml:lang">>,<<"en">>},{<<"type">>,<<"get">>},{<<"id">>,<<"aacfa">>}],[{xmlcdata,<<"\n">>},{xmlel,<<"query">>,[{<<"xmlns">>,<<"jabber:iq:roster">>}],[]},{xmlcdata,<<"\n">>}]},{state,{socket_state,gen_tcp,#Port<0.58993>,<0.2652.0>},ejabberd_socket,#Ref<0.0.1.25301>,false,<<"12664578908237388886">>,undefined,c2s,c2s_shaper,false,false,false,false,[verify_none,compression_none],true,{jid,<<"test1">>,<<"localhost">>,<<"D-5">>,<<"test1">>,<<"localhost">>,<<"D-5">>},<<"test1">>,<<"localhost">>,<<"D-5">>,{{1458,41617,630679},<0.2653.0>},{2,{{<<"test2">>,<<"localhost">>,<<>>},{{<<"test1">>,<<"localhost">>,<<>>},nil,nil},nil}},{2,{{<<"test2">>,<<"localhost">>,<<>>},{{<<"test1">>,<<"localhost">>,<<>>},nil,nil},nil}},{0,nil},undefined,undefined,{userlist,none,[],false},c2s,ejabberd_auth_internal,{{127,0,0,1},41928},[],active,[],inactive,undefined,undefined,1000,undefined,300,300,false,0,0,true,<<"en">>},{jid,<<"test1">>,<<"localhost">>,<<"D-5">>,<<"test1">>,<<"localhost">>,<<"D-5">>},{jid,<<"test1">>,<<"localhost">>,<<>>,<<"test1">>,<<"localhost">>,<<>>}],[]},{ejabberd_hooks,safe_apply,3,[{file,"src/ejabberd_hooks.erl"},{line,382}]},{ejabberd_hooks,run_fold1,4,[{file,"src/ejabberd_hooks.erl"},{line,365}]},{ejabberd_c2s,session_established2,2,[{file,"src/ejabberd_c2s.erl"},{line,1268}]},{p1_fsm,handle_msg,10,[{file,"src/p1_fsm.erl"},{line,582}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,240}]}]}
I have ejabberd 16.02.26 and my module code is:
mod_confirm_delivery.erl
This module is working fine with ejabberd 2.1.13 but i want to upgraded my ejabberd. I can't understand what is the problem and how can I resolve this error.
undef error means the function or module is not found. The most likely error is that the mod_confirm_delivery.beam file is not in Erlang VM path.
You should try moving the compiled beam file with other ejabberd beam files or try setting the path used to launch Erlang to the directory where your mod_confirm_delivery.beam file is located. This is the -pa option of the Erlang VM.
If your code if in right place, other option is that the function is undefined. The hook tries to call mod_confirm_delivery:send_packet/4. Your code is wrong as it indeed does not defined send_packet/4 but only send_packet/3. You need to update your code to match new signature for user_send_packet hook:
user_send_packet(Packet, C2SState, From, To) -> Packet
In case of doubt, you can refer to official hook list in ejabberd documentation: https://docs.ejabberd.im/developer/hooks/
I'm trying to write a DocPad plugin to import MongoDB docs into the DocPad database for use in a static website. The source code is at https://github.com/nfriedly/docpad-plugin-mongodb and it's based on https://github.com/docpad/docpad-plugin-tumblr

And, when I include the module in my project, it just hangs after this:

(And if I visit localhost:9778, it just hangs and never loads a page)
It seems like it only displays logs from plugins after the first pass is complete, so I started adding throw statements to see what it was doing. It seems that it imports things from mongo successfully, and it creates the document, but when the plugin calls document.action 'load', (err) ->, that callback is never fired.
Can anyone provide some guidance on what I'm messing up and how to get things working smoothly?
Fixed it. The TaskGroup library (apparently) once had a .once('complete', callback) event that no longer works. Switching it to .done(callback) (and fixing a couple of other small bugs) got me working now.
It still gives me the "Error: Didn't place the skeleton as the desired structure already exists" but the tests all pass now, so I'll call it a win.
