#23 | 30534 | Russell C. Jackson (Rusty) | Added journal directories to replication reset cleanup. | ||
#22 | 30226 | Russell C. Jackson (Rusty) | Switched order of journals.rotated and journals.rep | ||
#21 | 30166 | Russell C. Jackson (Rusty) | Fixed logic with replays to handle the different journal locations. | ||
#20 | 29965 | Russell C. Jackson (Rusty) |
Changes to directories, commands and journalPrefix to implement new process to keep journal rotation to the same volume as the logs volume, but to still move journals to the checkpoints directory so they get backed up. Also compresses journals to save space. |
||
#19 | 29760 | Russell C. Jackson (Rusty) | Added code to replay journals.rep folders to offline_db as well. | ||
#18 | 29021 | Russell C. Jackson (Rusty) | Added checkpoint running checks to prevent multiple runs of scripts from overlapping. | ||
#17 | 27627 | Russell C. Jackson (Rusty) | Changed P4MASTER to P4MASTERHOST | ||
#16 | 27166 | Russell C. Jackson (Rusty) | Changed RC stop/start to stop_p4d and start_p4d | ||
#15 | 25863 | Russell C. Jackson (Rusty) | Added missing call to get_offline_journalnum | ||
#14 | 25861 | Russell C. Jackson (Rusty) | Changes to recreate_db_sync_replica.sh to work with changes to backup functions. | ||
#13 | 25857 | Russell C. Jackson (Rusty) | Added 2nd rsync to cover journal files getting deleted during the rsync. | ||
#12 | 25824 | Russell C. Jackson (Rusty) | Fix issue with rotated journals during checkpoint rebuild. | ||
#11 | 25078 | Russell C. Jackson (Rusty) | Corrected P4LOGS to LOGS | ||
#10 | 24858 | Russell C. Jackson (Rusty) | Set rpl.journalcopy.location=1 and removed all journals.rep references since it won't be needed anymore. | ||
#9 | 23680 | Russell C. Jackson (Rusty) |
New script to copy over shelved files that verify -t schedules incorrectly. Defaulted RSYNCUSER to OSUSER to eliminate the need to check to see if RSYNCUSER is set. |
||
#8 | 23541 | Russell C. Jackson (Rusty) |
Added handling for a different OSUSER on the master than on the replica for rsync. Just add RSYNCUSER to the p4_1.vars file to enable. |
||
#7 | 23247 | Russell C. Jackson (Rusty) |
Modified the checkpoints folder to include an extension of the master or edge server.id to support sharing the data volume between a master and a workspace edge server in the same data center. Updated recover_edge to use variables appropriately and fixed a bug in the naming of the checkpoint file. |
||
#6 | 22981 | Russell C. Jackson (Rusty) | Made files writeable so they are easier to update once on the server. | ||
#5 | 22869 | Russell C. Jackson (Rusty) | Updated to only send email on error. | ||
#4 | 22757 | Russell C. Jackson (Rusty) |
Added P4SVRPORT to use to make the server listen on just the port number. Changed P4PORT to include the hostname to eliminate a bug where the ticket is not issued by the master as it should be when rpl.forward.login is set up. Created a p4login_master and updated appropriate scripts to use it. This actually isn't necessary with the change to include the hostname in P4PORT since the ticket will be valid on all servers in the group, but this covers configurations that aren't using rpl.forward.login. |
||
#3 | 22697 | Russell C. Jackson (Rusty) | Handle existing rotated logs, and remove check_disk_space from log reports since people monitor disk space with monitoring systems. | ||
#2 | 22696 | Russell C. Jackson (Rusty) | Updates to support using journalnum in rotate_last_run_logs. | ||
#1 | 22693 | Russell C. Jackson (Rusty) |
Branched a Unix only version of the SDP. Removed extra items to create a cleaner tree. Moved a few items around to make more sense without Windows in the mix. |
||

#8 | 21579 | Russell C. Jackson (Rusty) |
Additional rm commands to make sure that we cleaned up both P4ROOT and OFFLINE_DB. A customer indicated that the save directory was not cleaned up, so I just changed it to clean up both directories. |
||
#7 | 21178 | Russell C. Jackson (Rusty) |
Change the SDP so that root and offline_db can be on different volumes and still accomplish a fast database recovery using recreate_db_checkpoint.sh and recreate_db_sync_replica.sh. This is done by switching the links now rather than moving the db files. |
||
#6 | 20940 | Russell C. Jackson (Rusty) |
Drop JOURNALNUM from the rotated log names because it forces you to wait to rotate the prior logs until you get the journal number and creates a problem where the error that you couldn't get the journal number ends up at the end of the previous days log file, and that is what gets email out. That causes confusion for the person trying to see what the error is. Moved all rotate_last_run_logs up to the point right after we set the environment. |
||
#5 | 20937 | Russell C. Jackson (Rusty) | Added check to exit if we are not on a replica server. | ||
#4 | 20749 | C. Thomas Tyler |
Approved and committed, but I believe that the shared data setting is always set to false on the master and we should look at fixing that in another change. Enhanced p4login again. Improvements: Default behavior with no arguments gives the desired results. For example, if run on a master, we login on the super user P4USER to P4PORT. If run on a replica/edge and auth.id is set, we login P4USER to the P4TARGET port of the replica. All other login functionality, such as logging in the replication service user on a replica, logging in supplemental automation users, is now accessed via new flags. A usage message is now available via '-h' and '-man' options. The new synopsys is: p4login [<instance>] [-p <port> | -service] [-automation] [-all] The <instance> parameter is the only non-flag positional parameter, and can be ommitted if SDP_INSTANCE is already defined (as is typical when called by scripts). With this change, several other scripts calling either the 'p4login' script or 'p4 login' commands were normalized to call p4login as appropriate given the new usage. Reviewer Note: Review p4login first, then other files. Most changes are in p4login. In other scripts callling p4login, calls similar to: $P4BIN -u $P4USER -p $P4PORT login < /path/to/pwd are replaced with: $P4CBIN/p4login In other scritps calling p4login, calls similar to: $P4BIN -p $P4MASTERPORT login < /path/to/pwd are replaced with: $P4CBIN/p4login -p $P4MASTERPORT Note that, if auth.id is set, calling 'p4login' actually has the same behavior as 'p4login -p $P4MASTERPORT', since p4login called on a replica with auth.id set will just login to the master port anyway. Depending on intent, sometimes $P4BIN/p4login -service is used. == Misc Cleanup == In doing the cleanup: * Fixed a hard-coding-to-instance-1 bug in broker_rotate.sh. * Fixed an inconsistency in recreate_db_sync_replica.sh, where it did just a regular login rather than a login -a as done in other places for (for compatibility with some multi-interface NIC card configs). == p4login Call Normalization == Code cleanup was done to normalize calls to p4login, such that: 1) the call starts with $P4CBIN/p4login (not the hard-coded path), and 2) logic to redirect sdtout/stderr to /dev/null was removed, since it's not necessary with p4login. (And if p4login ever does generate any unwanted output, we only fix it in one place). == Tweak to instance_vars.template == This change includes a tweak to set P4MASTERPORT dynamically on a replica to ensure the value precisely matches P4TARGET for the given replica. This will reduce a source of problems when SSL is used, as it is particularly sensitive to the precise P4PORT values used, and will also help for environments which have not yet set auth.id. If the port cannot be determined dynamically, we fall back to the old logic using the assigned value. == Tweak to SDP_ALWAYS_LOGIN behavior == This used to default to 1, now it defaults to 0. At this point we should no longer need to force logins, and in fact doing so can get into a 'p4 login' hang situation with auth.id set. Best to avoid unnecessary logins if we already have a valid ticket. (I think the need to force a login may have gone away with p4d patches). == Obsolete Script == With this change, svclogin.sh is now obsolete. All it was doing was a few redundant 'p4 login' commands followed by a call to p4login anyway. == Testing == Our test suite doesn't fully cover this change, so additional manual testing was done in the Battle School lab environment. |

Per discussion: s/checkpoints.rep/journals.rep/g This directory name changed, used in the journalPrefix configurable, is intended to clarify that the should be targeted to for a FAST volume for use with journalcopy, rather than the LARGE volume as would be implied when using a directory with "checkpoints" in the name. |

Moved password and users into the config directory to allow for instance specific users and passwords. Ran into a case where two different teams were sharing the same server hardware and needed this type of differentiation. Surprised that we haven't hit this sooner. Also defaulted mkdirs to use the numeric ports since this is the most common installation. |

Renamed weekly_sync_replica.sh to recreate_db_sync_replica to be consistent with early rename of weekly_checkpoint.sh. Changed crontab.replica to only run recreate_db_sync_replica when the master runs recreate_db_checkpoint.sh Use the switch_db files function in the sync_replica script and added additional logging and error checking. #review Sorry Tom, I was wrong about being done. I just found this stuff while reviewing my prior changes to recreate_db_checkpoint.sh and backup_functions.sh |

Reworked the log rotation stuff in backup_functions.sh to make it cleaner and handle the new log from recreate_offline_db.sh. Modified recreate_offline_db.sh to add comments about a bad checkpoint. Also made it create its own log file since it isn't doing a checkpoint. Removed the log rotation for the same reason. Moved the LOGFILE setting out to all of scripts to make it more obvious for future scripts that you need to set that variable in your script so that it doesn't just default to checkpoint.log. Moved the functions in weekly_backup.sh and recreate_offline_db.sh into backup_functions.sh where they belong for consistency. Modified backup_functions.sh to use a consistent naming convention for all the rotated log files rather than checkpoint.log being unique. Replaced all back ticks with the newer bash $() method. Removed all of the line wrapping since I am pretty sure that none of us are working on an 80 character terminal these days and it is easier to read this way. |

- Ensure backup scripts are run as the OSUSER (to prevent accidental running as root); - in scripts where LOGFILE value is changed from the 'checkpoint.log' set by set_vars, ensure the new assignment is before check_dirs is called, otherwise errors could be written to the 'wrong' log - in 'die()' - detect if running from terminal & also send output to stderr |

Normalized P4INSTANCE to SDP_INSTANCE to get Unix/Windows implementations in sync. Reasons: 1. Things that interact with SDP in both Unix and Windows environments shoudn't have to account for this obscure SDP difference between Unix and Windows. (I came across this doing CBD work). 2. The Windows and Unix scripts have different variable names for defining the same concept, the SDP instance. Unix uses P4INSTANCE, while Windows uses SDP_INSTANCE. 3. This instance tag, a data set identifier, is an SDP concept. I prefer the SDP_INSTANCE name over P4INSTANCE, so I prpose to normalize to SDP_INSTANCE. 4. The P4INSTANCE name makes it look like a setting that might be recognized by the p4d itself, which it is not. (There are other such things such as P4SERVER that could perhaps be renamed as a separate task; but I'm not sure we want to totally disallow the P4 prefix for variable names. It looks too right to be wrong in same cases, like P4BIN and P4DBIN. That's a discussion for another day, outside the scope of this task). Meanwhile: * Fixed a bug in the Windows 2013.3 upgrade script that was referencing undefined P4INSTANCE, as the Windows environment defined only SDP_INSTANCE. * Had P4INSTANCE been removed completely, this change would likely cause trouble for users doing updates for existing SDP installations. So, though it involves slight technical debt, I opted to keep a redundant definition of P4INSTANCE in p4_vars.template, with comments indicating SDP_INSTANCE should be used in favor of P4INSTANCE, with a warning that P4INSTANCE may go away in a future release. This should avoid unnecessary upgrade pain. * In mkdirs.sh, the varialbe name was INSTANCE rather than SDP_INSTANCE. I changed that as well. That required manual change rather than sub/replace to avoid corrupting other similar varialbe names (e.g. MASTERINSTANCE). This is a trivial change technically (a substitute/replace, plus tweaks in p4_vars.template), but impacts many files. |

Updated copyright date to 2015 Updated shell scripts to require an instance parameter to eliminate the need for calling p4master_run. Python and Perl still need it since you have to set the environment for them to run in. Incorporated comments from reviewers. Left the . instead of source as that seems more common in the field and has the same functionality. |
