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: https://swarm.workshop.perforce.com/projects/perforce-software-sdp/view/main/doc/SDP_Legacy_Upgrades.Unix.html The SDP should always be upgraded to the latest version first before Helix Core binaries p4d/p4broker/p4p are upgraded using the SDP upgrade.sh script. 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, p4broker, p4p, or any 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. There can be multiple SDP instances on a given server machine. This script will upgrade the SDP on the machine, and thus after the upgrade all instances will immediately use new SDP scripts and updated instance configuration files, e.g. the /p4/common/config/p4_N.vars files. However, all instances will continue running the same Helix Core binaries. Any live running Helix Core server process on the machine are unaffected by the upgrade of SDP. This script will upgrade the SDP on a single machine. If your Perforce Helix topology has multiple machines, the SDP should be upgraded on all machines. The upgrade of SDP on multiple machines can be done in any order, as there 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). Planning Recap: 1. The SDP can be upgraded without downtime when this script is used, i.e. when the starting SDP version is 2020.1 or later. 2. Upgrade SDP on all machines, in any order, before upgrading p4d and other Helix binaries. == NFS Sharing of HxDepots == In some environments, the HxDepots volume is shared across multiple server machines with NFS, typically mounted as /hxdepots. This script updates the /hxdepots/p4/common and /hxdepots/sdp directories, both of which are on the NFS mount. Thus upgrading SDP on a single machine will effectively and immediately upgrade the SDP on all machines that share /hxdepots from the same NFS-mounted storage. This is a safe and valid configuration, as upgrading the SDP does not affect any live running p4d servers. == 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 is a manual operation. The SDP tarball must be extracted such that the 'sdp' directory appears as <HxDepots>/downloads/new/sdp, where <HxDepots> defaults to /hxdepots. To determine the value for <HxDepots> at your site you can run the following: bash -c 'cd /p4/common; d=\$(pwd -P); echo \${d%/p4/common}' On this machine, that value is: $HxDepots Following are sample commands to acquire the latest SDP, to be executed as the user $SDPOwner: cd $HxDepots [[ -d downloads ]] || mkdir downloads cd downloads [[ -d new ]] && mv new old.\$(date +'%Y%m%d-%H%M') curl -s -k -O $SDPTarballURL mkdir new cd new tar -xzf ../$SDPTarball After extracting the SDP tarball, cd to the directory where this sdp_upgrade.sh script resides, and execute it from there. cd $HxDepots/downloads/new/sdp/Server/Unix/p4/common/sdp_upgrade ./sdp_upgrade.sh -man == 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: <HxDepots>/p4/common.bak.<YYYYMMDD-hhmm> 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, /p4/common/bin/p4_vars. 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 exists below the '### MAKE LOCAL CHANGES HERE' tag will be split into 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) - KEEPLOGS - KEEPCKPS - KEEPJNLS For instance_vars files, preserved settings are: - MAILTO - MAILFROM - P4USER - P4MASTER_ID - SSL_PREFIX - P4PORTNUM - P4BROKERPORTNUM - P4MASTERHOST - PROXY_TARGET - PROXY_PORT - PROXY_MON_LEVEL - PROXY_V_FLAGS - P4DTG_CFG - SNAPSHOT_SCRIPT - SDP_ALWAYS_LOGIN - SDP_AUTOMATION_USERS - SDP_MAX_START_DELAY_P4D - SDP_MAX_START_DELAY_P4BROKER - SDP_MAX_START_DELAY_P4P - SDP_MAX_STOP_DELAY_P4D - SDP_MAX_STOP_DELAY_P4BROKER - SDP_MAX_STOP_DELAY_P4P - VERIFY_SDP_SKIP_TEST_LIST - 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: $DeprecatedFilesListFile 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 provides guidance on any post-processing steps. For some releases, this may include upgrades to crontabs. OPTIONS: -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. -L <log> 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. HELP OPTIONS: -h Display short help message -man Display man-style help message FILES AND DIRECTORIES: Name: SDPCommon Path: /p4/common Notes: This sdp_upgrade.sh script updates files in and under this folder. Name: HxDepots Default Path: /hxdepots Notes: The folder containing versioned files, checkpoints, and numbered journals, and the SDP itself. This is commonly a mount point. Name: DownloadsDir Default Path: /hxdepots/downloads Name: SDPInstallRoot Path: /p4 EXAMPLES: This script must be executed from 'sdp_upgrade' directory in the extracted SDP tarball. Typical operation starts like this: cd /hxdepots/downloads/new/sdp/Server/Unix/p4/common/sdp_upgrade ./sdp_upgrade.sh -h All following examples assume operation from that directory. Example 1: Prelight check only: sdp_upgrade.sh -p Example 2: Preview mode: sdp_upgrade.sh Example 3: Live operation: sdp_upgrade.sh -y LOGGING: 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-specific 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-upgrade 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." ### ### Keep this block in case the undocumented '-I' flag becomes documented. ### # The custom pre-upgrade script is executed after standard preflight # checks complete successfully. If the '-I' flag is used to ignore the # status of preflight checks, the custom pre-upgrade script is # executed regardless of the status of preflight checks. Preflight # checks are executed before actual upgrade processing commences. If a # custom pre-upgrade script indicates a failure, the overall upgrade # process aborts. msg " 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 is successful. Success or failure of pre- and post- upgrade scripts is reported 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 script. TIP: Be sure to fully test custom scripts in a test environment before incorporating them into an upgrade on production systems.

#42 | 30924 | C. Thomas Tyler |
Fixed an obscure "one day a month" bug that caused sdp_upgrade.sh to fail to detect the SDP version from the version file if released on the 20th of any given month. |
||
#41 | 30911 | C. Thomas Tyler | Adjusted format of generated files in sdp_ugprade.sh for release. | ||
#40 | 30509 | C. Thomas Tyler |
Tweaked proxy handling to generate a cleaner command line (as seen in ps -ef), eliminating null or duplicate values for proxy.monitor.level setting. This change makes p4d_base more robust even inf the instance vars settings are slightly misconfigured, e.g. a null value for PROXY_MON_LEVEL. #review-30510 |
||
#39 | 30508 | C. Thomas Tyler |
sdp_upgrade.sh did not preserve PROXY_PORT setting. Fixed. |
||
#38 | 30382 | C. Thomas Tyler | Updated SDP_INSTANCE_VARS_FORMAT version to 1.12. | ||
#37 | 30223 | C. Thomas Tyler |
Changed so 'p4d -cshow' calls in SDP shell environment mechanism use a copy of db.config to avoid issues with database locking. #review-30224 |
||
#36 | 29945 | C. Thomas Tyler | Bumped format of instance vars file. | ||
#35 | 29746 | C. Thomas Tyler |
Moved proxy '-e 3072' flag from p4p_base to Instance Vars file so it can be changed on a per-instance basis. It is now part of the def'n of PROXY_V_FLAGS. Moved PROXY_MON_LEVEL from p4_vars to Instance Vars file so it can be changed on a per-instance basis. Updated format settings in sdp_upgrade.sh, and added PROXY_MON_LEVEL to list of user settings to be preserved during SDP upgrades. #review-29747 |
||
#34 | 29609 | C. Thomas Tyler | Updated data format tags per SDP relesae process docs. | ||
#33 | 29491 | C. Thomas Tyler | Fixed bug where SDP ugprade disabled parallel checkpoints. | ||
#32 | 29420 | C. Thomas Tyler |
For parallel checkpoints, provide a way to specify '-N' parallel threads. #review-29421 |
||
#31 | 29396 | C. Thomas Tyler |
Doc improvements to SDP Instance Vars file re: MAILTO/MAILFROM settings. Tweaked Shellcheck SC<NNNN> tags to re-achieve shellcheck compliance. #review-29397 @daniel_ferrara |
||
#30 | 29355 | C. Thomas Tyler |
Added 'perl' as a required utility, capturing the fact that a dependency on perl now exists. |
||
#29 | 29243 | C. Thomas Tyler |
Fixed issue with sdp_upgrade.sh where extraction of values with a '=' in the value were not extracted correctly. For example, the p4_N.vars file could contain a value like so: export PROXY_V_FLAGS="-v net.autotune=1" This was parsed with: cut -d '=' -f 2, returning incomplete text: -v net.autotune (sans the "=1" on the right side). The fix was done by changing, in some places: cut -d '=' -f 2 with a more robust expression: perl -pe 's|^.*?=||g' In some cases where the value to the right of the '=' was reliably simple, e.g. for something like SDP_INSTANCE_VARS_FORMAT=1.5, the simpler 'cut' expression was left in place. The perl expression is used in places where the right-side of the assignment could possibly be a more complex value, possibly including an '=' sign. Note: sed was explored, but Perl was ultimately selected as the 'sed' regular expressions, even extended ones with '-E', do not support lazy regex macthing, as needed for this expression. |

#28 | 29232 | C. Thomas Tyler |
Added regression test for new parallel checkpoint feature. #review-29220 |

#21 | 28569 | C. Thomas Tyler |
Fixed an issue where some preflight failures could be ignored, changing return code for do_preflight_checks() from 0 to "$ErrorCount". Also, changes in behavior to undocumented '-I' flag: If '-I' is specified, the ErrorCount is reset to zero after preflight checks, so we don't get a FAILURE indication if the upgrade succeeded despite ignored warnings. This also allows custom post-processing scripts to execute upon successful completion of an upgrade with ignored warnings. Any new errors subsequent to preflight checks will result in a FAILURE message. #review-28570 |
