Python script reading an Excel file stops executing in Task Scheduler - python-2.7

A python 2.7 script, executed by Task Scheduler running on Windows Server 2012 (64 bit), ends without raising an exception at the point where it is opening an existing XLS file. Creating the Dispatch works fine (try/except not shown):
xlApp = win32com.client.DispatchEx('Excel.Application')
but right after that:
try:
log_message("Opening Excel Workbook object for the attachment using password '%s'" % email_found['PASSWORD'])
workbook = xlApp.Workbooks.Open(attachment, False, False, None, email_found['PASSWORD'])
log_message("Workbook opened, produced object with type '%s'" % type(workbook).__name__)
except Exception, e:
log_message("Exception opening workbook")
message = "Exception raised : %s" % str(e)
log_message(message, 'ERROR')
xlApp.Quit()
return 22
log_message() writes to a log file and optionally sends an email. The first message appears, and that's the end of the log file. Excel shows up as running in Task Manager, and the task shows as running in Task Scheduler.
The very same script, when run in a command shell by the same user, completes successfully. The very same script, when run in Task Scheduler on a Win7 box, completes successfully.
Other information:
The user whose account runs the task is a local administrator. I have tried two such users, and the same thing happens for both.
There is only the one instance of Excel (2010) installed on the box.
The file whose full path is in 'attachment' definitely exists, and can be opened interactively by Excel.
The string stored at email_found['PASSWORD'] contains the correct password for the XLS file.
I found some posts that mention the necessity of having one or the other (or both) of these directories:
C:\Windows\SysWOW64\config\systemprofile\Desktop
C:\Windows\System32\config\systemprofile\Desktop
Both are present for me (they're empty).
I'm running this script on Windows, rather than using xlrd on our preferred Linux platform, because xlrd does not support password protected XLS files. The XLS file is sent to us every week day by a client.
Any suggestions are most welcome, and thanks in advance.

I had a similar problem. But when I configured the task in TaskScheduler, I changed the configuration from "run whether the user is logged on or not" to "run when the user is logged on". And it worked! My script went to the OneDrive folder and read and extract the data from the selected excel.

Unable to run queries in SQL Lab in Apache Superset

I'm unable to run queries in SQL Lab. As soon as I run the query, Result sections shows {e} and query history says failed. Attaching the screenshot.
Resolved this one by looking through dev tools for exact exceptions.
This one has to do with the Signal alarms. Since superset is not supported with Windows, you will need to pass the exceptions on enter and on exit methods in core.py. It should be located in the file ~ C:\python\venv\Lib\site-packages\superset\utils
Comment Try in the below method and add pass:
def enter(self):
def exit(self, type, value, traceback):

Where are the EMR logs that are placed in S3 located on the EC2 instance running the script?

The question: Imagine I run a very simple Python script on EMR - assert 1 == 2. This script will fail with an AssertionError. The log the contains the traceback containing that AssertionError will be placed (if logs are enabled) in an S3 bucket that I specified on setup, and then I can read the log containing the AssertionError when those logs get dropped into S3. However, where do those logs exist before they get dropped into S3?
I presume they would exist on the EC2 instance that the particular script ran on. Let's say I'm already connected to that EC2 instance and the EMR step that the script ran on had the ID s-EXAMPLE. If I do:
[n1c9#mycomputer cwd]# gzip -d /mnt/var/log/hadoop/steps/s-EXAMPLE/stderr.gz
[n1c9#mycomputer cwd]# cat /mnt/var/log/hadoop/steps/s-EXAMPLE/stderr
Then I'll get an output with the typical 20/01/22 17:32:50 INFO Client: Application report for application_1 (state: ACCEPTED) that you can see in the stderr log file you can access on EMR:
So my question is: Where is the log (stdout) to see the actual AssertionError that was raised? It gets placed in my S3 bucket indicated for logging about 5-7 minutes after the script fails/completes, so where does it exist in EC2 before that? I ask because getting to these error logs before they are placed on S3 would save me a lot of time - basically 5 minutes each time I write a script that fails, which is more often than I'd like to admit!
What I've tried so far: I've tried checking the stdout on the EC2 machine in the paths in the code sample above, but the stdout file is always empty:
What I'm struggling to understand is how that stdout file can be empty if there's an AssertionError traceback available on S3 minutes later (am I misunderstanding how this process works?). I also tried looking in some of the temp folders that PySpark builds, but had no luck with those either. Additionally, I've printed the outputs of the consoles for the EC2 instances running on EMR, both core and master, but none of them seem to have the relevant information I'm after.
I also looked through some of the EMR methods for boto3 and tried the describe_step method documented here: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/emr.html#EMR.Client.describe_step - which, for failed steps, have a FailureDetails json dict response. Unfortunately, this only includes a LogFile key which links to the stderr.gz file on S3 (even in that file doesn't exist yet) and a Message key which contain a generic Exception in thread.. message, not the stdout. Am I misunderstanding something about the existence of those logs?
Please feel free to let me know if you need any more information!
It is quite normal that with log collecting agents, the actual logs files doesn't actually grow, but they just intercept stdout to do what they need.
Most probably when you configure to use S3 for the logs, the agent is configured to either read and delete your actual log file, or maybe create a symlink of the log file to somewhere else, so that file is actually never writen when any process open it for write.
maybe try checking if there is any symlink there
find -L / -samefile /mnt/var/log/hadoop/steps/s-EXAMPLE/stderr
but it can be something different from a symlink to achieve the same logic, and I ddint find anything in AWS docs, so most probably is not intended that you will have both S3 and files at the same time and maybe you wont find it
If you want to be able to check your logs more frequently, you may want to think about installing a third party logs collector (logstash, beats, rsyslog,fluentd) and ship logs to SolarWinds Loggly, logz.io, or set up a ELK (Elastic search, logstash, kibana)
You can check this article from Loggly, or create a free acount in logz.io and check the lots of free shippers that they support

Issue with uploading GeoLite2-City.mmdb.missing file in mautic

I have a mautic marketing automation installed on my server (I am a beginner)
However i replicated this issue when configuring GeoLite2-City IP lookup
Automatically fetching the IP lookup data failed. Download http://geolite.maxmind.com/download/geoip/database/GeoLite2-City.mmdb.gz, extract if necessary, and upload to /home/ol*****/public_html/mautic4/app/cache/prod/../ip_data/GeoLite2-City.mmdb.
What i attempted
i FTP into the /home/ol****/public_html/mautic4/app/cache/prod/../ip_data/GeoLite2-City.mmdb. directory
uploaded the file (the original GeoLite2-City.mmdb has '0 byte', while the newly added file is about '6000 kb'
However, once i go back into mautic to implement the lookup, the newly added file reverts back to '0byte" and i still cant get the IP lookup configured.
I have also changed the file permission to 0744, but the issue still replicates.
Did you disable the cron job which looks for the file? If not, or if you clicked the button again in the dashboard, it will overwrite the file you manually placed there.
As a side note, the 2.16 release addresses this issue, please take a look at https://www.mautic.org/blog/community/announcing-mautic-2-16/.
Please ensure you take a full backup (files and database) and where possible, run the update at command line to avoid browser timeouts :)

Sitecore purge/write log immediately

Is there a way to purge the log in Sitecore such that logs are written immediately. It's for production debugging.
Also strolling through log files, there are number of log files e.g. log.date.text and log.date.time.txt. Which one is the latest i.e. with our without time.
You can use next module for production server if you have remote access there :
https://marketplace.sitecore.net/Modules/S/Sitecore_Log_Analyzer.aspx
Other option is to use this module:
https://marketplace.sitecore.net/Modules/S/Sitecore_ScriptLogger.aspx
The log with no timestamp in the file name is the first on for that day.
A new log file is created each time the application pool restarts.
If you haven't changed any of the default log4net settings then the initial log file will be in the format log.yyyyMMdd.txt, each subsequent restart will cause a new file to be generated with the following format log.yyyyMMdd.HHmmss.txt.
The latest log file for the day will be the file with the latest timestamp.

Why LOAD DATA LOCAL INFILE will work from the CLI but not in application?

The problem:
My C++ application connects to a MySQL server, reads the first/header line of each db export.txt, makes a create table statement to prepare for the import and executes that against the database (no problem with that, the table appears just as intended) -- but when I try and execute the LOAD DATA LOCAL INFILE to import the data into the newly created table, I get the error "The used command is not allowed with this MySQL version". But, this works on the CLI! When I execute this command on the CLI using mysql -u <user> -p<password> -e "LOAD DATA LOCAL INFILE 'myfile.txt' INTO TABLE mytable FIELDS TERMINATED BY '|' LINES TERMINATED BY '\r\n';" it works flawlessly?
The Situation:
My company gets a large quantity of database exports (160 files/10gb of .txt files that are '|' delimited) from our vendors on a monthly basis that have to replace the old vendor lists. I am working on a smallish C++ app to deal with it on my work desktop. The application is meant to set up the required tables, import the data, then execute a series of intermediate queries against multiple tables to assemble information in a series of final tables, which is then itself exported and uploaded to the production environment, for use in the companies e-commerce website.
My Setup:
Ubuntu 12.04
MySQL Server v. 5.5.29 + MySQL Command Line client
Linux GNU C++ Compiler
libmysqlcppconn is installed and I have the required mysqlconn library linked in.
I have already overcome/tried the following issues/combinations:
1.) I have already discovered (the hard way) that LOAD DATA [LOCAL] INFILE statements must be enabled in the config -- I have the "local-infile" option set in the configuration files for both client and server. (fixed by updating the /etc/mysql/my.cnf with "local-infile" statements for the client and server. NOTE: I could have used the --local-infile=1 to restart the mysql-server, but this is my local dev environment so I just wanted it turned on permanently)
2.) LOAD DATA LOCAL INFILE seems to fail to perform the import (from the CLI) if the target import file does not have execute permissions enabled (fixed with chmod +x target_file.txt)
3.) I am using the mysql root account in my application code (because its my localhost, not production and this particular program will never run on a production server.)
4.) I have tried executing my compiled binary program using the sudo command (no change, same error "The used command is not allowed with this MySQL version")
5.) I have tried changing the ownership of the binary file from my normal login to root (no change, same error "The used command is not allowed with this MySQL version")
6.) I know the libcppmysqlconn is working because I am able to connect and perform the CREATE TABLE call without a problem, and I can do other queries and execute statements
What am I missing? Any suggestions? Thanks in advance :)
After much diligent trial and error working with the /etc/mysql/my.cfg file (I know this is a permissions issue because it works on the command line, but not from the connector) and after much googling and finding some back alley tech support posts I've come to conclude that the MySQL C++ connector did not (for whatever reason) decide to implement the ability for developers to be able to allow the local-infile=1 option from the C++ connector.
Apparently some people have been able to hack/fork the MySQL C++ connector to expose the functionality, but no one posted their source code -- only said it worked. Apparently there is a workaround in the MySQL C API after you initialize the connection you would use this:
mysql_options( &mysql, MYSQL_OPT_LOCAL_INFILE, 1 );
which apparently allows the LOAD DATA LOCAL INFILE statements to work with the MySQL C API.
Here are some reference articles that lead me to this conclusion:
1.) How can I get the native C API connection structure from MySQL Connector/C++?
2.) Mysql 5.5 LOAD DATA INFILE Permissions
3.) http://osdir.com/ml/db.mysql.c++/2004-04/msg00097.html
Essentially if you want the ability to use the LOAD DATA LOCAL INFILE functionality from a programmatic Connector API -- you have to use the mysql C API or hack/fork the existing mysql C++ api to expose the connection structure. Or just stick to executing the LOAD DATA LOCAL INFILE from the command line :(
