Description

This tool is able to communicate with Retrace server: create a new task, restart an existing task, get and set values of an existing task. If kerberos ticket is available, all communication uses it. To stop using the ticket you must destroy it (kdestroy).

Operations

create

Create a new task. Task can be either http task (COREFILE is compressed and sent through http API), manager task (/manager site must be available) or ftp task (same as manager task, but uses ftp file). If none of the options "-t", "-m", or "-f" are given, the following logic is tried. If COREFILE is a local file, then the "-m" option is used, otherwise the "-f" option is used.

restart

Restart an existing task. Note that restarting an existing task removes all files inside the results directory.

set

Write (set) information on an existing task. Available only for manager and ftp task. See retrace-server-interact for setting the success or failure of a task. See Set Options section for list of set options available.

get

Read (get) information on an existing task. If no parameters specified the output will default to the task status. See Get Options section for list of get options available.

batch

Very similar to create (has the same parameters) but also waits until task is finished. If the task finishes successfully thebacktrace is downloaded

Common Options

-h,  --help

Display help and exit.

-n,  --no-verify

Do not verify certificate. (off by default)

-p,  --password PASSWORD

Password of the task (only for http tasks)

-s,  --server SERVER

URL for Retrace server. If not specified local server is tried and if not available https://retrace.fedoraproject.org/ is used.

-v,  --verbose

Be verbose. Note this also turns on debug logging for create, batch or restart operations.

Create or Batch Options

-bz BUGZILLANO, --bugzillano BUGZILLANO

Write the bugzillano field in the task to BUGZILLANO. Available only for manager and ftp task.

-c CASENO, --caseno CASENO

Write the caseno field in the task to CASENO. Available only for manager and ftp task.

-e EMAIL, --email EMAIL

Write the email field in the task to EMAIL. Available only for manager and ftp task.

-d, --no-md5

Do not calculate md5sum on the task. Available only for manager and ftp task.

-u, --userspace_core

The COREFILE specified is userspace core.

-k, --kernel_core

The COREFILE specified is kernel core. (default)

-t, --http

The COREFILE is assumed to be a local file, submitted through http

-f, --ftp

The COREFILE is assumed to be on the ftp server as configured in retrace-server

-m, --manager

The COREFILE is assumed to be either a URL that is wget-able or a local file

-i, --interactive

Create an interactive (persistent) task that may be accessed later in an interactive debug session. Without this option, manager and ftp tasks are interactive, and http tasks are not.

--vmem VMEM

Virtual memory file VMEM needed for retracing kernel vmcore snapshots. Only valid for kernel cores.

-r KERNELVER, --kernelver KERNELVER

Force the kernel version in the COREFILE to KERNELVER. Only valid for kernel cores.

-o OS_RELEASE, --os_release OS_RELEASE

Force the version of the operating system in COREFILE to OS_RELEASE. Only valid for userspace cores.

-p PACKAGE, --package PACKAGE

Force the version of the RPM package corresponding to COREFILE to PACKAGE. Only valid for userspace cores.

-x EXECUTABLE, --executable EXECUTABLE

Force the COREDUMP executable to EXECUTABLE. Only valid for userspace cores.

Restart Options

-bz BUGZILLANO, --bugzillano BUGZILLANO

Write the bugzillano field in the task to BUGZILLANO. Available only for manager and ftp task.

-c CASENO, --caseno CASENO

Write the caseno field in the task to CASENO. Available only for manager and ftp task.

-e EMAIL, --email EMAIL

Write the email field in the task to EMAIL. Available only for manager and ftp task.

-r KERNELVER, --kernelver KERNELVER

Force the kernel version in the task to KERNELVER. Only valid for kernel cores.

Get Options

-b, --backtrace

Return the backtrace in a file in the current directory

-bz, --bugzillano

Return the value of the bugzillano field in the task to the terminal. Available only for manager and ftp task.

-c, --caseno

Return the value of the caseno field in the task to the terminal. Available only for manager and ftp task.

-e, --email

Return the value of the email field in the task to the terminal. Available only for manager and ftp task.

-m, --md5sum

Return the md5sum field in the task to the terminal. Available only for manager and ftp task.

-t, --status

Return the status field in the task to the terminal. If no option is given, this field is selected as default.

Set Options

-bz BUGZILLANO, --bugzillano BUGZILLANO

Write the bugzillano field in the task to BUGZILLANO. Available only for manager and ftp task.

-c CASENO, --caseno CASENO

Write the caseno field in the task to CASENO. Available only for manager and ftp task.

-e EMAIL, --email EMAIL

Write the email field in the task to EMAIL. Available only for manager and ftp task.

Examples

Create a task from a local file (kernel vmcore)

retrace-server-task create ./localfile

Create a task where the file (kernel vmcore) exists on FTP server

retrace-server-task create 012345-vmcore

Create a task for kernel vmcore snapshot with vmem file included

retrace-server-task create 012345-vmcore.vmss --vmem 012345-vmcore.vmem

Batch run local file on https://retrace.fedoraproject.org/ (usperspace core)

retrace-server-task batch -u -t -o "Fedora release 25 (Twenty five)" -p \
"coreutils-8.25-17.fc25" -x "/usr/bin/sleep" ./coredump

Read the md5sum field for task 925483242

retrace-server-task get --md5sum 925483242

Write the caseno field for task 925483242 to 01234567

retrace-server-task set --caseno 01234567 925483242

Write the bugzillano field for task 31415926 to 53589793, 23846264

retrace-server-task set --bugzillano 53589793,23846264 31415926

Restart task 790216008

retrace-server-task restart 790216008

Restart task 164167944 forcing kernel version to 4.18.0-80.el8.x86_64

retrace-server-task restart 790216008 --kernelver 4.18.0-80.el8.x86_64
