4.6. b2conditionsdb: Conditions DB interface#

This tool provides a command line interface to all the tasks related to the Conditions database: manage globaltags and iovs as well as upload new payloads or download of existing payloads.

The usage of this tool is similar to git: there are sub commands like for example tag which groups all actions related to the management of globaltags. All the available commands are listed below.

Users need a valid JSON Web Token (JWT) to authenticate to the conditions database when using this tool. For practical purposes, it is only necessary to know that a JWT is a string containing crypted information, and that string is stored in a file. More informations about what a JWT is can be found on Wikipedia.

The tool automatically queries the JWT issuing server (https://token.belle2.org) and gets a valid token by asking the B2MMS username and password. The issued “default” JWT has a validity of 1 hour; after it expires, a new JWT needs to be obtained for authenticating the conditions database. When retrieved by this tool, the JWT is stored locally in the file ${HOME}/b2cdb_${BELLE2_USER}.token.

Some selected users (e.g. the calibration managers) are granted a JWT with an extended validity (30 days) to allow smooth operations with some automated workflows. Such “extended” JWTs are issued by a different server (https://token.belle2.org/extended). B2MMS username and password are necessary for getting the extended JWT. The extended JWT differs from the default JWT only by its validity and can be obtained only by manually querying the alternative server. If queried via web browser, a file containing the extended JWT will be downloaded in case the user is granted it. The server can also be queried via command line using wget --user USERNAME --ask-password --no-check-certificate https://token.belle2.org/extended or curl -u USERNAME -k https://token.belle2.org/extended.

If the environment variable ${BELLE2_CDB_AUTH_TOKEN} is defined and points to a file containing a valid JWT, the b2conditionsdb tools use this token to authenticate with the CDB instead of querying the issuing server. This is useful when using an extended token. Please note that, in case the JWT to which ${BELLE2_CDB_AUTH_TOKEN} points is not valid anymore, the b2conditionsdb tools will attempt to get a new one and store it into ${BELLE2_CDB_AUTH_TOKEN}. If a new extended token is needed, it has to be manually obtained via https://token.belle2.org/extended and stored into ${BELLE2_CDB_AUTH_TOKEN}.

Optional Arguments

--debugging

Enable debugging of http traffic

--base-url

URI for the base of the REST API, if not given a list of default locations is tried

--auth-token

JSON Web Token necessary for authenticating to the conditions database. Useful only for debugging, since by default the tool automatically gets a token for you by asking the B2MMS username and password. If the environment variable $BELLE2_CDB_AUTH_TOKEN points to a file with a valid token, such token is used (useful for automatic workflows).

4.6.1. Sub-command b2conditionsdb diff#

This command allows to compare two globaltags. It will show the changes in a format similar to a unified diff but by default it will not show any context, only the new or removed payloads. Added payloads are marked with a + in the first column, removed payloads with a -

If --full is given it will show all payloads, even the ones common to both globaltags. The differences can be limited to a given run and limited to a set of payloads names using --filter or --exclude. If the --regex option is supplied the search term will be interpreted as a python regular expression where the case is ignored.

Changed in version release-03-00-00: modified output structure and added --human-readable

Changed in version after: release-04-00-00 added parameter --checksums and --show-ids

4.6.2. Sub-command b2conditionsdb download#

This command allows to download the information from one or more globaltags from the central database to be used locally.

The command requires at least one tag name to download. It will check for existing payloads in the output directory and only download payloads which are not present or don’t have the expected checksum.

By default this script will create a local directory called conditions/ which contains a metadata.sqlite with all the payload information of all selected globaltags and sub directories containing all the payload files.

This can be changed by specifying a different name for the metadata file using the -o argument but the payloads will always be saved in sub directories in the same directory as the sqlite file.

Changed in version release-04-00-00: Previously this command was primarily intended to download payloads for one globaltag and optionally create a text file with payload information as well as download all necessary file. This has been changed and will now create a sqlite file containing the payload metadata. If you need the old behavior please use the command b2conditionsdb-legacydownload

4.6.3. Sub-command b2conditionsdb dump#

New in version release-03-00-00.

This command will dump the payload contents stored in a given payload. One can either specify the payloadId (from a previous output of b2conditionsdb iov), the payload name and its revision in the central database, or directly specify a local database payload file.

Examples

Dump the content of a previously downloaded payload file:

$ b2conditionsdb dump -f centraldb/dbstore_BeamParameters_rev_59449.root

Dump the content of a payload by name and revision directly from the central database:

$ b2conditionsdb dump -r BeamParameters 59449

Dump the content of the payload by name which is valid in a given globaltag for a given experiment and run:

$ b2conditionsdb dump -g BeamParameters main_2021-08-04 0 0

Or directly by payload id from a previous call to b2conditionsdb iov:

$ b2conditionsdb dump -i 59685

Usage

Depending on whether you want to display a payload by its id in the database, its name and revision in the database or from a local file provide one of the arguments -i, -r, -f or -g

4.6.6. Sub-command b2conditionsdb legacydownload#

This command allows to download a globaltag from the central database to be used locally, either as lookup directory for payloads or as a standalone local database if –create-dbfile is specified.

The command requires the TAGNAME to download and optionally an output directory which defaults to centraldb in the local working directory. It will check for existing payloads in the output directory and only download payloads which are not present or don’t have the expected checksum.

One can filter the payloads to be downloaded by payload name using the –filter, –exclude and –regex options.

New in version release-04-00-00: This has been renamed from download and is kept for compatibility

Warning

Downloading a globaltag should be done in the new format creating sqlite database files. Please use this legacy tool only for downloading “small” globaltags or very few payloads.

Sub-command b2conditionsdb tag merge#

This command allows to merge a number of globaltags into a single globaltag. Payloads from later globaltags in the list of arguments are used to fill gaps present in earlier globaltags.

The result is equivalent to having multiple globaltags setup in the conditions access for basf2 (highest priority goes first).

Warning:

The order of the globaltags is highest priority first, so payloads from globaltags earlier on the command line will be taken with before globaltags from later tags.

This command requires that all globaltags are overlap free.

For each globaltag in the list we copy all payloads to the output globaltag if there is no payload of that name valid for the given interval of validity in any previous globaltags in the list.

If the payload overlaps partially with a payload from a previous globaltag in the list the interval of validity is shortened (and possibly split) to not overlap but to just fill the gaps.

For example:

globaltag A contains

payload1, rev 2, valid from 1,0 to 1,10
payload1, rev 3, valid from 1,20 to 1,22
payload2, rev 1, valid from 1,0 to 1,-1

globaltag B contains

payload1, rev 1, valid from 1,1 to 1,30
payload2, rev 2, valid from 0,1 to 1,20

Then running b2conditionsdb tag merge -o output A B, the output globaltag after the merge will contain:

payload1, rev 2, valid from 1,0 to 1,10
payload1, rev 1, valid from 1,11 to 1,19
payload1, rev 3, valid from 1,20 to 1,22
payload1, rev 1, valid from 1,23 to 1,30
payload2, rev 2, valid from 0,1 to 0,-1
payload2, rev 1, valid from 1,0 to 1,-1

When finished, this command will print a table of payloads and their validity and from which globaltag they were taken. If --dry-run is given it will only print the list of payloads.

Optionally one can specify --run-range to limit the run range for which the merging should take place. In the example above, running with --run-range 1 0 1 21 the result would be

payload1, rev 2, valid from 1,0 to 1,10
payload1, rev 1, valid from 1,11 to 1,19
payload1, rev 3, valid from 1,20 to 1,21
payload2, rev 1, valid from 1,0 to 1,21

Sub-command b2conditionsdb tag runningupdate#

This command will calculate and apply the necessary updates to a running globaltag with a given staging globaltag

Running tags are defined as “immutable for existing data but conditions for newer runs may be added” and the only modification allowed is to add new payloads for new runs or close existing payloads to no longer be valid for new runs.

This command takes previously prepared and validated payloads in a staging globaltag and will then calculate which payloads to close and what to add to the running globaltag.

For this to work we require

  1. A running globaltag in the state “RUNNING”

  2. A (experiment, run) number from which run on the update should be valid. This run number needs to be

    1. bigger than the start of validity for all iovs in the running tag

    2. bigger than the end of validity for all closed iovs (i.e. not valid to infinity) in the running tag

  3. A staging globaltag with the new payloads in state “VALIDATED”

    1. payloads in the staging tag starting at (0,0) will be interpreted as starting at the first valid run for the update

    2. all other payloads need to start at or after the first valid run for the update.

    3. The globaltag needs to be gap and overlap free

    4. All payloads in the staging tag should have as last iov an open iov (i.e. valid to infinity) but this can be disabled.

The script will check all the above requirements and will then calculate the necessary operations to

  1. Add all payloads from the staging tag where a start validity of (0, 0) is replaced by the starting run for which this update should be valid.

  2. close all iovs for payloads in the running tags just before the corresponding iov of the same payload in the staging tag, so either at the first run for the update to be valid or later

  3. Optionally, make sure all payloads in the staging tag end in an open iov.

Example:

running tag contains

payload1, rev 1, valid from 0,1 to 1,0
payload1, rev 2, valid from 1,1 to -1,-1
payload2, rev 1, valid from 0,1 to -1,-1
payload3, rev 1, valid from 0,1 to 1,0
payload4, rev 1, valid from 0,1 to -1,-1
payload5, rev 1, valid from 0,1 to -1,-1

staging tag contains

payload1, rev 3, valid from 0,0 to 1,8
payload1, rev 4, valid from 1,9 to 1,20
payload2, rev 2, valid from 1,5 to 1,20
payload3, rev 2, valid from 0,0 to -1,-1
payload4, rev 1, valid from 0,0 to 1,20

Then running b2conditionsdb tag runningupdate running staging --run 1 2 --allow-closed, the running globaltag after the update will contain

payload1, rev 1, valid from 0,1 to 1,0
payload1, rev 2, valid from 1,1 to 1,1
payload1, rev 3, valid from 1,2 to 1,8
payload1, rev 4, valid from 1,9 to 1,20
payload2, rev 1, valid from 0,1 to 1,4
payload2, rev 2, valid from 1,5 to 1,20
payload3, rev 1, valid from 0,1 to 1,0
payload3, rev 2, valid from 1,2 to -1,-1
payload4, rev 1, valid from 0,1 to 1,20
payload5, rev 1, valid from 0,1 to -1,-1

Note that

  • the start of payload1 and payload3 in staging has been adjusted

  • payload2 in the running tag as been closed at 1,4, just before the validity from the staging tag

  • payload3 was already closed in the running tag so no change is performed. This might result in gaps but is intentional

  • payload4 was not closed at rim 1,2 because the staging tag had the same revision of the payload so the these were merged to one long validity.

  • payload5 was not closed as there was no update to it in the staging tag. If we would have run with --full-replacement it would have been closed.

  • if we would have chosen --run 1 1 the update would have failed because payload1, rev2 in running starts at 1,1 so we would have a conflict

  • if we would have chosen --run 1 6 the update would have failed because payload2 in the staging tag starts before this run

  • if we would have chosen to open the final iovs in staging by using --fix-closed, payload1, rev 4; payload2, rev 2 and payload4 rev 1 would be valid until -1,-1 after the running tag. In fact, payload 4 would not be changed at all.
