It supports a variety of use cases for replaying checkpoints and journals, including: * Seeding or Reseeding a replica or edge server. * Loading a checkpoint on the commit, e.g. in a recovery scenario. Checkpoints and/or journals can be specified in one of two ways: they can be specified as parameters to this script, or they can be determined by this script if they appear in the SDP standard location according to the journalPrefix standard. They key methods are: * Specify the path to the checkpoint to replay. The checkpoint can be in the form of a compressed .gz file, an uncompressed checkpoint file, or a directory (for parallel checkpoints). * Use '-latest' to have this script find the latest checkpoint available. For a commit server, /p4/N/checkpoints/p4_N is searched. For other servers, their journalPrefix is used. The timestamp on the latest available *.md5 file is used to determine what checkpoint is the latest available, regardless of checkpoint form (compressed or uncompressed file, or a directory for parallel checkpoints). * Use '-latest_jnls' to find the latest checkpoint as with '-latest', and then also find and replay any available subsequent numbered journals. * Use '-jo' (\"journal only\") to specify path(s) to one or more numbered journals to be supplied as parameters to this script. Journal files provided may be compressed or uncompressed. * Use '-jo_latest' to find any numbered journals available to be replayed based on the journal counter of the data set. At the start of processing, preflight checks are done. Preflight checks include: * The specified checkpoint and corresponding *.md5 file must exist. * The specified checkpoint can be a compressed or uncompressed file or a directory (for parallel checkpoints). * All journal files to replay (if any are specified) must exist. * The \$P4ROOT/server.id file must exist, unless '-s' is specified. * If the \$P4ROOT/server.id file exists and '-s' is specified, the values must match. * The \$P4ROOT/license file must exist, unless '-l' is specified or if the replica type does not require a license (such as an edge server). * The SDP structure and key files must exist. * Disk space checks are done to attempt to determine if sufficient space is available to replay the checkpoint. If the preflight passes, the p4d_N service is shutdown. The p4broker_N service is shutdown if it is configured. If a P4LOG file exists, it is moved aside so there is a fresh p4d server log corresponding to operation after the checkpoint load. If a P4JOURNAL file exists, it is moved aside as the old journal data is no longer relevant after a checkpoint replay. (Exception: If the P4JOURNAL is speciffed in a list of journals to reply, then it is not moved aside). Next, any existing state* files in P4ROOT are removed. Next, any existing database it is files in P4ROOT are preserved and moved aside, unless '-R' is specified to remove them. Next, the specified checkpoint is loaded. Upon successful completion, 'p4d -xu' is executed (by default) to help ensure the service can be started with the p4d binary used to replay the checkpoint. Then the Helix Core service is started with the current p4d binary. If the server to be started is a replica, the serviceUser configured for the replica is logged into the P4TARGET server. Any needed 'p4 trust' and 'p4 login' commands are done to enable replication. Note that this part of the processing will fail if the correct super user password is not stored in the standard SDP password file, /p4/common/config/.p4passwd.p4_N.admin After starting the server, a local 'p4 trust' is done if needed, and then a 'p4login -service -v' and 'p4login -v'. By default, the p4d_N service is started, but the p4broker_N service is not. Specify '-b' to restart both services. Finally, the offline_db is rebuilt using the same specified checkpoint and journals. ARGUMENTS AND OPTIONS: <checkpoint> Specify the path to the checkpoint file or directory to load. Exactly one checkpoint must be specified. If a checkpoint file is specified, a serial checkpoint replay will be done. If a checkpoint directory is specified, a parallel replay will be done using the individual files in the directory. For checkpoint files: The file may be a compressed or uncompressed checkpoint, and it may be a case sensitive or case-insensitive checkpoint. The checkpoint file must have a corresponding *.md5 checksum file in the same directory, with one of two name variations: If the checkpoint file is /somewhere/foo.gz, the checksum file may be named /somewhere/foo.gz.md5 or /somewhere/foo.md5. For checkpoint directories: This option is required unless the '-latest' option is used. <jnl.1> [<jnl.2> ...] Specify the path to the one or more journal files to replay after the checkpoint, in the correct sequence order. -latest Specify this as an alternative to providing a specific checkpoint file or directory. The script will then search for the latest *.md5 file in the standard checkpoints directory and use that to replay. The most recent *.md5 file determines which checkpoint to load, be it a file or directory (for parallel checkpoints). This option is mutually exclusive with '-latest_jnls'. -latest_jnls This option is similar to '-latest'. However, with '-latest_jnls', in addition to replaying the latesst checkpoint, any subsequent numbered journals available in the standard checkpoints directory are also replayed. This option will only replay numbered journals, not the live P4JOURNAL file. However, if the \$P4JOURNAL is provided, then it will be replayed after all available numbered journals are replayed. This option is mutually exclusive with '-latest'. If used with '-jo', where the checkpoint and possibly some numbered journals will already have been replayed into P4ROOT, then the meaning of this option changes. It will replay needed numbered journal up to the latest available, so long as those journals appear in the standard checkpoints directory with the usual naming convention. With this option, the journal needed are calculated based on the journal counter stored in database in the P4ROOT dir. -R Specify '-R' to remove db.* files in P4ROOT rather than moving them aside. By default, databases are preserved for possible future for investigation. A folder named 'MovedDBs.<datestamp>' is created under the P4ROOT directory, and databases are moved there. Keeping an extra set of databases requires sufficient disk space to hold the extra set of db.* files. If -R specified, old databases in P4ROOT are removed, along with state* and other files, and the server.locks directory. -F <SafetyFactor> When replacing an existing set of db.* files, a safety factor is used. This is simply the factor by which the size of pre-existing databases is multiplied when comparing against available disk space. Specify '-F 0' to disable the safety factor check. The disk space safety check is only meaningful if P4ROOT was previously populated with a full set of data. Specifying a nubmer greater than 1, say 1.2 (the default) gives more breathing room. Specifying a value lower than 1, say 0.95, may be OK if you are certain the expanded-from-a-checkpoint db.* files are significantly smaller than size the prior set of db.* files. This option is mutually exclusive with '-R'. If '-R' is used, databases are removed, and there is no need to calculate disk space. -i <instance> Specify the SDP instance. This can be omitted if SDP_INSTANCE is already defined. -s <ServerID> Specify the ServerID. This value is written into \$P4ROOT/server.id file. If no \$P4ROOT/server.id file exists, this flag is required. If the \$P4ROOT/server.id file exists, this argument is not needed. If this '-s <ServerID>' is given and a \$P4ROOT/server.id file exists, the value in the file must match the value specified with this argument. -t <Type> Specify the replica type tag if the checkpoint to be loaded is for an edge server or replica. The set of valid values for the replica type tag are defined in the documentation for mkrep.sh. See: mkrep.sh -man If the type is specified, the '-s <ServerID>' is required. If the SDP Server Spec Naming Standard is followed, the ServerID specified with '-s' will start with 'p4d_'. In that case, the value for '-t edge' value is inferred, and '-t' is not required. If the type is specified or inferred, certain behaviors change based on the type: * If the type is edge, only the correct edge-specific subset of database tables are loaded. * The P4ROOT/license file check is suppressed unless the type is ha, ham, fs, for fsm (standby replicas usable with 'p4 failover'). Do not use this '-t <Type>' option if the checkpoint being loaded is for a commit server. For an edge server, an edge seed checkpoint created with edge_dump.sh must be used if the edge is filtered, e.g. if any of the *DataFilter fields in the server spec are used. If the edge server is not filtered by means other than being an edge server (for which certain tables are filtered by nature), a standard full checkpoint from the commit can be used. For a filtered forwarding replica, a proper seed checkpoint must be loaded. This can be created on the commit using key options to p4d, including '-P <ServerID> -jd <SeedCkp' on the commit (possibly using the 'offline_db' to avoid downtime, similar to how edge_dump.sh works for edge servers). WARNING: While this script is useful for seeding a new edge server, this script is NOT to be used for recovering or reseeding an existing edge server, because all edge-local database tables (mostly workspace data) would be lost. To recover an existing edge server, see the recover_edge.sh script. Warning: If this option is specified with the incorrect type for the checkpoint specified, results will be unpredictable. -verify default [-delay <delay>] -verify \"Verify Options\" [-delay <delay>] Specify '-verify' to initiate a call to 'p4verify.sh' after the server is online. On a replica, this can be useful to cause the server to pull missing archive files from its P4TARGET server. If this load_checkpoint.sh script is used in a recovery situation for a commit server, this '-verify' option can be used to discover if archive files are missing after the metadata is recovered. The 'p4verify.sh' script has a rich set of options. See 'p4verify.sh -man' for more info. The options to pass to p4verify.sh can be passed in a quoted list, or '-verify default' can be used to indicate these default options: $DefaultVerifyOptions By default, a fast verify is used if the p4d version is new enough (2021.1+). See 'p4verify.sh -man' for more information, specifically the description of the '-o MISSING' option. In all cases, p4verify.sh is invoked as a background process; this load_checkpoint.sh script does not wait for it to complete. The p4verify.sh script will email as per normal when it completes. The optional delay option specifies how long to wait until kicking off the p4verify.sh command, in seconds. The default is $DefaultVerifyDelay seconds. This is intended to give the replica time get get caught up with metadata before the archive pulls are scheduled. The delay is a workaround for job079842. This option is cannot be used with '-no_start'. -c Specify that SSL certificates are required, and not to be generated with 'p4d_N -Gc'. By default, if '-c' is not supplied and SSL certs are not available, certs are generated automatically with 'p4d_N -Gc'. -l Specify that the server is to start without a license file. By default, if there is no \$P4ROOT/license file, this script will abort. Note that if '-l' is specified and a license file is actually needed, the attempt this script makes to start the server after loading the checkpoint will fail. If '-t <type>' is specified, the license check is skipped unless the type is 'ha', 'ham', 'fs,' or 'fsm'. Replicas that are potential targets for a 'p4 failover' need a license file for a failover to work. -r Specify '-r' to replay only to P4ROOT. By default, this script replays both to P4ROOT and the offline_db. -no_start Specify '-no_start' to avoid starting the p4d service after loading the checkpoint. This option is cannot be used with '-verify'. -no_xu Specify '-no_xu' to skip the 'p4d -xu' step that upgrade the database schema. By default, a 'p4d -xu' is done to help ensure the service can be started with the current p4d binary after the checkpoint is replayed. If the p4d binary used to replay the checkpoint is a newer major version than the one used to create the checkpoint, the service will not start after the replay until the 'p4d -xu' step is done. If this '-no_xu' option is used and the p4d binary is a newer major version, have a plan to get the 'p4d -xu' done before the service is started. In EXAMPLES below, see the example titled \"Multi Pass Replay of Checkpoints and Journals\" for an example of using this option as part of a migration procedure. -jo <jnl.1> [<jnl.2> ...] Specify '-jo' to replay only one or more numbered journals without first replaying a full checkpoint. With this option, the cleanup that normally occurs before the replay is disabled. The db.* and state* files in P4ROOT, as well as P4LOG and P4JOURNAL files, etc. are left in place. With '-jo', the paths to journal files must be specified. This option is mutually exclusive to the similar option '-jo_latest'. This option implies '-r'. -jo_latest Specify '-jo_latest' to replay only one or more numbered journals without first replaying a full checkpoint. With this option, the cleanup that normally occurs before the replay is disabled. The db.* and state* files in P4ROOT, as well as P4LOG and P4JOURNAL files, etc. are left in place. With '-jo_latest', numbered journals to replay are calculated and determined, not specified as parameters. This option is mutually exclusive to the similar option '-jo'. This option implies '-r'. -b Specify '-b' to start the a p4broker process (if configured). By default the p4d process is started after loading the checkpoint, but the p4broker process is not. This can be useful to ensure the human administrator has an opportunity to do sanity checks before enabling the broker to allow access by end users (if the broker is deployed for this usage). -y Use the '-y' flag to bypass an interactive warning and confirmation prompt. -L <log> Specify the path to a log file. By default, all output (stdout and stderr) goes to: /p4/<instance>/logs/${ThisScript%.sh}.<timestamp>.log NOTE: This script is self-logging. That is, output displayed on the screen is simultaneously captured in the log file. Do not run this script with redirection operators like '> log' or '2>&1', and do not use 'tee.' -si Operate silently. All output (stdout and stderr) is redirected to the log only; no output appears on the terminal. -d Set debugging verbosity. -D Extreme debugging verbosity using bash 'set -x' mode. HELP OPTIONS: -h Display short help message -man Display man-style help message USAGE TIP: All the non-interactive examples below illustrate the practice of using redirects to create an extra log file named 'load.log' in the \$LOGS directory for the instance. This load.log file is identical to, and in addition to, the standard timestamped log generated by this script. The intent of this practice is to make it easier to find the log for the last checkpoint loaded on any given server machine. This convention is only useful if used consistently. Several examples below illustrate the instance option, '-i' option to specify the SDP instance. This is optional and can safely be omitted in an environment where the standard SDP shell environment is sourced on login, and where there is only a single instance on the server machine. EXAMPLES: EXAMPLE 1: Non-interactive Usage Non-interactive usage (bash syntax) to load a checkpoint: nohup $P4CBIN/load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025.gz -i 1 -y < /dev/null > /p4/1/logs/load.log 2>&1 & Then, monitor with: tail -f \$(ls -t \$LOGS/load_checkpoint.*.log|head -1)\\n EXAMPLE 2: Checkpoint Load then Verify, for the SDP Instance alpha. Non-interactive usage (bash syntax) to load a checkpoint followed by a full verify of recent archives files only with other options passed to verify.sh: nohup $P4CBIN/load_checkpoint.sh /p4/alpha/checkpoints/p4_alpha.ckp.95442.gz -i alpha -verify "-recent -nu -ns" -y < /dev/null > /p4/alpha/logs/load.log 2>&1 & EXAMPLE 3: Load Checkpoint and Journals Non-interactive usage (bash syntax) to loading a checkpoint and subsequent journals: nohup $P4CBIN/load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025.gz /p4/1/checkpoints/p4_1.jnl.4025 /p4/1/checkpoints/p4_1.jnl.4026 -i 1 -y < /dev/null > /p4/1/logs/load.log 2>&1 & Then, monitor with: tail -f \$(ls -t \$LOGS/load_checkpoint.*.log|head -1)\\n EXAMPLE 4: Interactive usage. Interactive usage to load a checkpoint with no license file. $P4CBIN/load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025.gz -i 1 -l With interactive usage, logging still occurs; all output to the screen is captured. Note that non-interactive usage with nohup is recommended for checkpoints with a long replay duration, to make operation more reliable in event of a shell session disconnect. Alternately, running interactively in a 'screen' session (if 'screen' is available) provides similar protection against shell session disconnects. EXAMPLE 5: Seed New Edge Seeding a new edge server. nohup $P4CBIN/load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025.gz -i 1 -s p4d_edge_syd < /dev/null > /p4/1/logs/load.log 2>&1 & WARNING: While this script is useful for seeding a new edge server, this script is NOT to be used for recovering or reseeding an existing edge server, because all edge-local database tables (mostly workspace data) would be lost. To recover an existing edge server, see the recover_edge.sh script. EXAMPLE 6: Seed New Edge and Verify Seeding a new edge server and then do a verify with default options. nohup $P4CBIN/load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025.gz -i 1 -s p4d_edge_syd -verify default < /dev/null > /p4/1/logs/load.log 2>&1 & EXAMPLE 7: Load a Parallel Checkpoint on an Edge and Verify Recent This non-interactive example loads a parallel checkpoint directory. The usage difference is that the checkpoint path provided is a parallel checkpoint directory rather than a single checkpoint file. This example loads the checkpoint for a new edge server, and verifes only the most recent 3 changes in each depot. The delay before calling p4verify.sh, 10 minutes (600) by default, is shortened to 5 seconds in this example. nohup $P4CBIN/load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025 -i 1 -s p4d_edge_syd -verify \"-o MISSING -recent=3 -ns -L /p4/1/logs/p4verify.fast_and_recent.log\" -delay 5 -y < /dev/null > /p4/1/logs/load.log 2>&1 & EXAMPLE 8: Multi Pass Replay of Checkpoints and Journals In this example, we want to use a multi-pass procedure involving replay of a checkpoint at one point in time, and then later replay subsequent numbered journals later. This method can be useful to reduce downtime required for migration procedures involving a checkpoint replay if the checkpoint replay takes a while, e.g. a few hours or more. The gist of the approach is to replay the checkpoint a day or so a head of the scheduled maintenance. Then replay subsequent numbered journals each day after. Then in the maintenance window, replay just the last numbered journal from the old environment in the new environment. This approach involves a few options: * When the checkpoint is replayed, '-no_start' and '-no_xu'. Either specify the path to the checkpoint, or use '-latest'. * When the numbered journals are replayed in days leading up to the maintenance window, use the '-jo_latest' option to replay only a numbered journal. * During the maintenance window, load any final numbered journals, then start the service. Pass 1, 3 days before maintenance: nohup load_checkpoint.sh -latest -no_start -no_xu -r -y < /dev/null > /p4/1/logs/load.log 2>&1 & Pass 2, 2 days before maintenance: nohup load_checkpoint.sh -jo_latest -no_start -no_xu -y < /dev/null > /p4/1/logs/load.log 2>&1 & Pass 3, 1 day before maintenance: nohup load_checkpoint.sh -jo_latest -no_start -no_xu -y < /dev/null > /p4/1/logs/load.log 2>&1 & Pass 4, during the maintenance window: nohup load_checkpoint.sh -jo_latest -y < /dev/null > /p4/1/logs/load.log 2>&1 & " fi exit 2 } #============================================================================== # Command Line Processing declare -i LoadOfflineDB=1 declare -i StartP4BrokerWhenDone=0 declare -i StartP4DWhenDone=1 declare -i Interactive=1 declare -i KeepRootDBs=1 declare -i shiftArgs=0 set +u while [[ $# -gt 0 ]]; do case $1 in (-i) SDPInstance="$2"; shiftArgs=1;; (-s) SetServerID="$2"; shiftArgs=1;; (-t) ReplicaTypeTag="$2"; shiftArgs=1;; (-verify) DoVerify=1; VerifyOptions="$2" shiftArgs=1;; (-delay) VerifyDelay="$2"; shiftArgs=1;; (-c) GenSSLCertsIfNeeded=0;; (-k) dbg "Ignoring obsolete -k option.";; # '-k' was replaced by '-R'.

Revised logic replaying checkpoints to select the most recent checkpoint regardless of whether it is parallel or not. This logic now applies consistently across scripts (even some not in this changelist that call functions in backup_functions.sh), such as sync_replica.sh, sync_replica.sh, load_checkpoint.sh, recover_edge.sh, etc. The edge_dump.sh script now creates parallel checkpoints if parallel checkpoints are configured. The load_checkpoint.sh now reliably detects the most recent checkpoint when '-latest' is used reliably, serial or parallel. This script now also finds checkpoints for a standby of an edge. Also fixed bug cleaning up old *.OK files from earlier parallel checkpoints. The recover_edge.sh script similarly detects the latest checkpoint correctly, serial or parallel. This chagne was tested with a new regression test suite that operates in a Battle School Lab environment, allowing for more sophisticated testing of sequences of operations. #review-30655 |
||
#43 | 30600 | C. Thomas Tyler | Silenced a shellcheck concern. | ||
#42 | 30456 | C. Thomas Tyler | Added P4D_VERSION to output. | ||
#41 | 30350 | C. Thomas Tyler | Tweaked example. | ||
#40 | 30349 | C. Thomas Tyler |
Fix to load_checkpoint.sh so '-jo' and 'jo_latest' do no imply '-no_xu', and documented the fact that the '-jo*' options do imply '-r'. |
||
#39 | 30340 | C. Thomas Tyler |
load_checkpoint.sh v3.0.0: Made suitable for multi-pass replay of checkpoint subsequent numbered journals. This enables a technique useful in reducing downtime for migrations involving replay of a checkpoint possibly days ahead of the cutover (one pass), and then later replaying numbered journals. #review-30341 |
||
#38 | 30236 | C. Thomas Tyler |
load_checkpoint.sh: Add '-no_start' option. #review-30237 |
||
#37 | 30100 | C. Thomas Tyler |
Fixed doc issues in load_checkpoint.sh. The'-v<N>' verosity control option was shown in the usage synopsis but was not implemented. The '-d/-D' options (which are documented and work as advertised) make the '-v' option (a carry over from an old script template) obsolete. Fixed other doc typos. No functional changes. #review-30101 @mark_zinthefer |
||
#36 | 29949 | C. Thomas Tyler | Added '-latest' option to synopsis for load_checkpoint.sh | ||
#35 | 29899 | C. Thomas Tyler | load_checkpoint.sh: Fixed warnings from 'find' call and fixed typo in error message. | ||
#34 | 29883 | C. Thomas Tyler | Added safey feature to defend against using '< /dev/null' and forgetting '-y'. | ||
#33 | 29881 | C. Thomas Tyler |
Added '-latest' option to load_checkpoint.sh. Selects latest checkpoint, be it a file (for serial checkpoints) or a directory (for parallel checkpoints). #review-29882 |
||
#32 | 29864 | C. Thomas Tyler |
load_checkpoint.sh v2.9: * Added support for replaying parallel checkpoint directories. * Changed order of operations so the replica service is started before the (optional) replay to the offline_db. * Fixed exit code bug where 'EXIT_CODE: 0' could be displayed even if there were errors. * Deprecated '-k' option to keep databases. Keeping metadata is now the default behavior. Added '-R' option to remove metadata. * Added a disk space safety check, projecting need based on size of previously existing db.* files. Added a '-F' safety factor option to control or bypass the safety. * Fixed some errors that could be encontered in some conditions when moving aside existing db.* and other files. * Enhanced audit trail and generally nicer output. * The server.locks directory is now removed. * The rdb.lbr table and server.pid files are now handled (moved or removed depending on -R, along db.* and other files). * Various doc improvements. * Added doc example, loading a parallel checkpoint on an edge. * Added doc tip re: the common practice of creating a log file name 'load.log' for non-interactive usage. * Enhanced so logic to infer the type tag, which had been applied to ServerID's specified with '-s', is now applied even if '-s' is not used. This results in less need to specify '-l' (to skip the license check) on server types like edges that don't need a license. * General internal improvements, moving toward the (not yet published) SDP Bash coding standard. #review-29865 |
||
#31 | 29316 | C. Thomas Tyler |
Enhanced robustness of start_p4d() and stop_p4d() interaction with systemd, and also in similar logic in load_checkpoint.sh. #review-29317 |
||
#30 | 29307 | C. Thomas Tyler |
load_checkpoint.sh: Added '-delay' option as a workaround for server job job079842. #review-29308 |
||
#29 | 29195 | C. Thomas Tyler | Fixed order-of-operations issue seen without standard shell environment. | ||
#28 | 29193 | C. Thomas Tyler |
load_checkpoint.sh v2.7.0: * If live P4JOURNAL is specified to replay, don't move it. * Added '-k' option to keep rather than delete db.* files. Updated test case to exercise new new options. With these changes, this script, originally focused on loading checkpoints on replicas/edge servers, is now also suited to support recovery. See also: SDP-582, for a separate script focused on recovery scenarios, which can call this script as needed. #review-29164 @robert_cowham |
||
#27 | 28836 | C. Thomas Tyler |
load_checkpoint.sh v2.6.2: * Added logic to avoid errors if broker startes slowly. * Format clarification to usage message for '-verify' option. * Fixed typos in doc and code comments. |
||
#26 | 28641 | C. Thomas Tyler |
Tweaked scripts to support IPv6 SSL prefixes. Added test script to test bash code snippets. First test is the snippet to check if SSL is enabled, and if so get the SSL prefix. |
||
#25 | 28587 | C. Thomas Tyler |
load_checkpoint.sh v2.6.0: * Added '-verify' option to call p4verify.sh from load_checkpoint.sh. Default is to do a 'fast verify' if possible (if p4d is 2021.1+). Other options to p4verify.sh can be passed. #review-28588 |
||
#24 | 28585 | C. Thomas Tyler |
load_checkpoint.sh v2.5.2: * Added logic to load edge servers. * Added '-t <Type>' flag to specifiy replica types, with logic to infer the value from '-s <ServerID>' if the SDP Server Spec Naming Standard is followed. * Fixed bug with failing to detect start of server with an untrusted SSL connection. * Refined logic for handling license file checks, eliminating needless warnings and errors. * Refined docs, with extra info for handling edge servers and filtered forwarding replicas. #review-28586 |
||
#23 | 28584 | C. Thomas Tyler |
load_checkpoint.sh v2.4.4: * Enhanced error message for case where '-s <ServerID>' disagrees with server.id file. |
||
#22 | 28219 | C. Thomas Tyler |
Fixed issue with slow p4d start causing 'p4login' failures. #review-28220 |
||
#21 | 28203 | C. Thomas Tyler | Optimization to avoid referencing Journals array if empty. | ||
#20 | 28168 | C. Thomas Tyler |
Enhanced load_checkpoint.sh to accept a list of journal files to replay following the checkpoint. Fixed issue with 'zcat' on Mac. |
||
#19 | 27722 | C. Thomas Tyler |
Refinements to @27712: * Resolved one out-of-date file (verify_sdp.sh). * Added missing adoc file for which HTML file had a change (WorkflowEnforcementTriggers.adoc). * Updated revdate/revnumber in *.adoc files. * Additional content updates in Server/Unix/p4/common/etc/cron.d/ReadMe.md. * Bumped version numbers on scripts with Version= def'n. * Generated HTML, PDF, and doc/gen files: - Most HTML and all PDF are generated using Makefiles that call an AsciiDoc utility. - HTML for Perl scripts is generated with pod2html. - doc/gen/*.man.txt files are generated with .../tools/gen_script_man_pages.sh. #review-27712 |
||
#18 | 27064 | C. Thomas Tyler |
Fixed issue where 'source p4_vars' hangs if load_checkpoint.sh is running. Added new semaphore file, $P4ROOT/P4ROOT_not_usable.txt. This is used in a way similar to 'offline_db_usable.txt' in the offline_db, except that this file only exists when the databases in P4ROOT are not usable. This is the opposite of how offline_db_usable.txt works, because P4ROOT is expected to be usable 99.9% fo the time. p4d_base will refuse to start p4d if this file exists, protecting against possible operator errors (like trying to start p4d when a checkpoint is still loading). Added check_file_dne() function to verify_sdp.sh to confirm a named file does not exist. Added checks in verify_sdp.sh that P4ROOT_not_usable.txt does not exist in P4ROOT or offline_db. Modified switch_db_files() (called by refresh_P4ROOT_from_offline_db.sh) to properly use the new P4ROOT_not_usable.txt safety file. Fixed bugs in p4d_base that could cause p4d_init.log to be overwritten if error output was generated. Removed call to 'backup_functions.sh' in p4d_base, as on balance it added more complexity than needed. #review-27065 |
||
#17 | 26940 | C. Thomas Tyler |
Fixed issue with load_checkpoint.sh not clearing journal.NNN file when working on a standby (journalcopy) replica, which prevented replication from automatically starting. These files are now moved aside. Removed undocumented edge processing logic determined to be unnecessary. Minor doc improvements. |
||
#16 | 26886 | C. Thomas Tyler |
Fixed issue in load_checkpoint.sh where the critical 'p4d -xu' step can fail due to lack of a license file with enough users for the data set. With this fix (borrowed from upgrade.sh), the critical upgrade step succeeds, and the user is not left with a failure in the middle of processing that would require manual cleanup. The p4d server will still refuse to start without a proper license later in the process, but at that we're at a cleaner break point in processing, and the failure mode is clearer to admins. |
||
#15 | 26825 | C. Thomas Tyler | Fixed order of operations issue when '-s <ServerID>' was specified. | ||
#14 | 26649 | Robert Cowham |
More SDP Doc tidy up. Removed some command summary files. |
||
#13 | 26457 | C. Thomas Tyler | Fixed typo for '-L' flag. | ||
#12 | 26444 | C. Thomas Tyler |
load_checkpoint.sh 2.3.x: * Patch for bug with missing variable initializations. * Does trusts and logins for services users as needed after loading checkpoint. * Enhanced preflight check. ServerID file now required (can be specified) * Now generates SSL certs if needed. * Enhanced docs. |
||
#11 | 26400 | C. Thomas Tyler |
Added refresh_P4ROOT_from_offline_db.sh. Updated backup_functions.sh to support functionality for db refresh. Upgrade start_p4d() and stop_p4d() to use systemd if available, else use the underlying SysV init scripts. Updated verify_sdp.sh to be called from other scripts (sans its own logging). Added many checks to verify_sdp.sh to support P4ROOT/offline_db swap. Logic in P4ROOT/offline_db swap is more careful about what gets swapped. Added start_p4broker() and stop_p4broker() that behave similarly. More shellcheck compliance. #review-26401 |
||
#10 | 25949 | C. Thomas Tyler | Fixed typo in variable name. | ||
#9 | 25938 | C. Thomas Tyler | Fixed bug in safety check. | ||
#8 | 25920 | C. Thomas Tyler |
Added new 'edge_vars' file to dynamically set list of edge-specific db tables based on current P4D version. Updated edge_dump.sh, recover_edge.sh, and load_checkpoint.sh to use the new edge_vars file. Made edge_dump.sh and recover_edge.sh shellcheck v0.6.0 compliant, along with load_checkpoint.sh. |
||
#7 | 25790 | C. Thomas Tyler |
load_checkpoint.sh v2.0.5: * Added support for handling case-insensitive and case sensitive checkpoints. This works if $P4DBIN is a symlink rather than a wrapper supplying '-C1', as the need for '-C1' is dynamically detected. (This was driven by a need to incorporate load_checkpoint.sh into case conversion orchestration scripts using p4migrate). * Added '-r' flag to load checkpoint into P4ROOT only, skipping offline_db. * Added '-b' flag to restart broker at the end. * Normalized to template.sh structure, with typical benefits (enhanced command line parsing, standard usage message, better documentation). * Added check for missing certificate.txt if using SSL. * Made shellcheck v0.6.0 compliant. |
||
#6 | 24602 | C. Thomas Tyler | Fixed a few obvious typos. | ||
#5 | 24599 | C. Thomas Tyler | Fixed obvious typo. | ||
#4 | 24482 | C. Thomas Tyler |
Fixed obvious typo. Removed redundant time as it clutters the output and introduces an unnecessary dependency. Change to new/unreleased script, bypassing review. |
||
#3 | 24374 | C. Thomas Tyler | Added actual file content. | ||
#2 | 24368 | C. Thomas Tyler |
load_checkpoint.sh v1.0.6: * Added safety warning and interactive confirmation. * Supports systemd init mechanism rather than SysV init scripts if systemd *.service files are configured. Uses 'sudo systemctl start/stop' calls for p4d and p4broker. Use SysV init scripts on other systems. * Fixed bug with cleanup steps not executing. TO DO: Normalize into template.sh style with auto-logging and standard command line flags. |
||
#1 | 24198 | C. Thomas Tyler |
Added utility script to load a specified checkpoint into both /p4/N/root and /p4/N/offline_db, including logic to managing p4d/p4broker processes, ensure no db.* files exist prior to replaying the checkoint, managing the offline_db_usable.txt file, etc. |
