USAGE for sdp_upgrade.sh v1.5.0:
sdp_upgrade.sh [-y] [-p] [-L <log>|off] [-D]
This script must be executed from 'sdp_upgrade' directory in the extracted SDP tarball.
Typical operation starts like this:
This script upgrades Perforce Helix Server Deployment Package (SDP) from
SDP 2020.1 to the version included in the latest SDP version, SDP
== Pre-Upgrade Planning ==
This script will upgrade the SDP if the pre-upgrade starting SDP version
is SDP 2020.1 or later, including any/all patches of SDP
If the current SDP version is older than 2020.1, it must first be upgraded
to SDP 2020.1 using the SDP Legacy Upgrade Guide. For upgrading from
pre-20.1 versions dating back to 2007, in-place or migration-style upgrades
can be done. See:
The SDP should always be upgraded to the latest version first before
Helix Core binaries p4d/p4broker/p4p are upgraded using the SDP
Upgrading the SDP first ensures the version of the SDP you have
is compatible with the latest versions of p4d/p4broker/p4p/p4, and
will always be compatible with all supported versions of these
Helix Core binaries.
When this script is used, i.e. when the current SDP version is 2020.1
or newer, the SDP upgrade procedure does not require downtime for any
running Perforce Helix services, such as p4d, p4broker, or p4p. This
script is safe to run in environments where live p4d instances are running,
and does not require p4d or other services to be stopped or upgraded.
Upgrade of the SDP is cleanly separate from the upgrade the Helix Core
binaries. The upgrade of the SDP can be done immediately prior to Helix
Core upgrades, or many days prior.
This script will upgrade the SDP on a single machine. If your Perforce
Helix topology has multiple machines, the SDP can be upgraded on all
machines in any order, as their is no cross-machine dependency requiring
the SDP to be the same version. (The order of upgrade of Helix Core services
and binaries such as p4d in global topologies with replicas and edge servers
does matter, but is outside the scope of this script).
1. The SDP can be upgraded without downtime when this script is used,
i.e. when the SDP version is 2020.1 or later.
2. Upgrade SDP on all machines, in any order, before upgrading p4d and other
== Acquiring the SDP Package ==
This script is part of the SDP package (tarball). It must be run from an
extracted tarball directory. Acquiring the SDP tarball manually operation
The SDP tarball must be extracted such that the 'sdp' directory appears as
<HxDepots>/downloads/new/sdp, where is <HxDepots> defaults to /hxdepots. To
determine the value for <HxDepots> at your site. On this machine, that
value is: /hxdepots
Following are sample commands to acquire the latest SDP, to be executed
as the user perforce:
[[ -d downloads ]] || mkdir downloads
[[ -d new ]] && mv new old.$(date +'%Y%m%d-%H%M')
curl -s -k -O https://swarm.workshop.perforce.com/projects/perforce-software-sdp/download/downloads/sdp.Unix.tgz
tar -xzf ../sdp.Unix.tgz
After extracting the SDP tarball, cd to the directory where this
sdp_ugprades.sh script resides, and execute it from there.
== Preflight Checks ==
Prior to upgrading, preflight checks are performed to ensure the
upgrade can be completed successfully. If the preflight checks
fail, the upgrade will not start.
Sample Preflight Checks:
* The existing SDP version is verified to be SDP 2020.1+.
* Various basic SDP structural checks are done.
* The /p4/common/bin/p4_vars is checked to confirm it can be upgraded.
* All /p4/common/config/p4_N.vars files are checked to confirm they can be upgraded.
== Automated Upgrade Processing ==
Step 1: Backup /p4/common.
The existing <HxDepots>/p4/common structure is backed up to:
Step 2: Update /p4/common.
The existing SDP /p4/common structure is updated with new
versions of SDP files.
Step 3: Generate the SDP Environment File.
Regenerate the SDP general environment file,
The template is /p4/common/config/p4_vars.template.
Step 4: Generate the SDP Instance Files.
Regenerate the SDP instance environment files for all instances based on
the new template.
The template is /p4/common/config/instance_vars.template.
For Steps 3 and 4, the re-generation logic will preserve current
settings. If upgrading from SDP r20.1, any custom logic that
exist below the '### MAKE LOCAL CHANGES HERE' tag will be
split it separate files. Custom logic in p4_vars will be moved
to /p4/common/site/config/p4_vars.local. Custom logic in
p4_N.vars files will be moved to /p4/common/site/config/p4_N.vars.local.
Note: Despite these changes, the mechanism for loading the SDP shell
environment remains unchanged since 2007, so it looks like:
$ source /p4/common/bin/p4_vars N
Changes to the right-side of assignments for specific are preserved
for all defined SDP settings. For p4_vars, preserved settings are:
- OSUSER (determined by current owner of /p4/common)
For instance_vars files, preserved settings are:
- The 'umask' setting.
- KEEPLOGS (if set)
- KEEPCKPS (if set)
- KEEPJNLS (if set)
Note that the above list excludes any values that are calculated.
Step 5: Remove Deprecated Files.
Deprecated files will be purged from the SDP structure. The list of
files to be cleaned are listed in this file:
Paths listed in this file are relative to the '/p4' directory (or
more accurately the SDP Install Root directory, which is always
'/p4' except in SDP test production environments).
Step 6: Update SDP crontabs.
No crontab updates are required for this SDP upgrade.
== Post-Upgrade Processing ==
This script provide guidance on any post-processing steps. For some
releases, this may include upgrades to crontabs.
-y Specify the '-y' option to confirm that the SDP upgrade should be done.
By default, this script operates in No-Op mode, meaning no actions
that affect data or structures are taken. Instead, commands that would
be run are displayed. This mode can be educational, showing various
steps that will occur during an actual upgrade.
-p Specify '-p' to halt processing after preflight checks are complete,
and before actual processing starts. By default, processing starts
immediately upon successful completion of preflight checks.
Specify the log file to use. The default is /tmp/sdp_upgrade.<timestamp>.log
The special value 'off' disables logging to a file. This cannot be
specified if '-y' is used.
-d Enable debugging verbosity.
-D Set extreme debugging verbosity.
-h Display short help message
-man Display man-style help message
FILES AND DIRECTORIES:
Notes: This sdp_upgrade.sh script updates files in and under this folder.
Default Path: /hxdepots
Notes: The folder containing versioned files, checkpoints, and numbered
journals, and the SDP itself. This is commonly a mount point.
Default Path: /hxdepots/downloads
This script must be executed from 'sdp_upgrade' directory in the extracted
SDP tarball. Typical operation starts like this:
All following examples assume operation from that directory.
Example 1: Prelight check only:
Example 2: Preview mode:
Example 3: Live operation:
This script generates a log file, ~/sdp_upgrade.<timestamp>.log
by default. See the '-L' option above.
CUSTOM PRE- AND POST- UPGRADE AUTOMATION HOOKS:
This script can execute custom pre- and post- upgrade scripts. This
can be useful to incorporate site-specifc elements of an SDP upgrade.
If the file /p4/common/site/upgrade/pre-sdp_upgrade.sh exists and is
executable, it will be executed as a pre-upgrade script. If the file
/p4/common/site/upgrade/post-sdp_upgrade.sh exists and is executable,
it will be executed as a post-ugprade script.
Pre- and post- upgrade scripts are passed the '-y' flag to confirm
actual processing is to be done. Custom scripts are expected to
operate in preview mode by default, taking no actions that affect data
(just as this script behaves). If this sdp_upgrade.sh script is given
the '-y' flag, that option is passed to the custom script as well,
indicating active processing should occur.
Pre- and post- upgrade scripts are expected to exit with a zero exit
code to indicate success, and non-zero to indicate failure.
The custom pre-upgrade script is executed after standard preflight
checks complete successfully. Preflight checks are executed before
actual upgrade processing commences. If a custom pre-upgrade script
indicates a failure, the overall upgrade process aborts.
The post-upgrade custom script is executed after the main SDP upgrade
Success or failure of pre- and post- upgrade scripts is repored in
the log. These scripts do not require independent logging, as all
standard and error output is captured in the log of this sdp_upgrade.sh
TIP: Be sure to fully test custom scripts in a test environment
before incorporating them into an upgrade on production systems.
An exit code of 0 indicates no errors were encountered during the
upgrade. A non-zero exit code indicates the upgrade was aborted
