## Synopsis

```shell copy
codeql execute upgrades [--threads=<num>] <options>... -- <dataset> <script>...
```

## Description

\[Plumbing] Run upgrade scripts on an existing raw QL dataset.

This command runs a particular sequence of upgrade scripts against the
dataset. It is the caller's responsibility that the "old" dbscheme of
each upgrade script matches the "new" dbscheme of the previous script
(or, for the first script, the current dbscheme of the dataset). If not,
an error will be reported.

## Primary options

#### `<dataset>`

\[Mandatory] Path to the raw QL dataset to upgrade.

#### `<script>...`

\[Mandatory] Paths to upgrade scripts to execute. (Each upgrade script
is a directory containing several files that define an upgrade
operation). They must be given in the order they are to be applied.

#### `--search-path=<dir>[:<dir>...]`

A list of directories under which QL packs may be found. Each directory
can either be a QL pack (or bundle of packs containing a
`.codeqlmanifest.json` file at the root) or the immediate parent of one
or more such directories.

If the path contains more than one directory, their order defines
precedence between them: when a pack name that must be resolved is
matched in more than one of the directory trees, the one given first
wins.

Pointing this at a checkout of the open-source CodeQL repository ought
to work when querying one of the languages that live there.

If you have checked out the CodeQL repository as a sibling of the
unpacked CodeQL toolchain, you don't need to give this option; such
sibling directories will always be searched for QL packs that cannot be
found otherwise. (If this default does not work, it is strongly
recommended to set up `--search-path` once and for all in a per-user
configuration file).

(Note: On Windows the path separator is `;`).

#### `--additional-packs=<dir>[:<dir>...]`

If this list of directories is given, they will be searched for packs
before the ones in `--search-path`. The order between these doesn't
matter; it is an error if a pack name is found in two different places
through this list.

This is useful if you're temporarily developing a new version of a pack
that also appears in the default path. On the other hand, it is _not
recommended_ to override this option in a config file; some internal
actions will add this option on the fly, overriding any configured
value.

(Note: On Windows the path separator is `;`).

### Options to control evaluation of upgrade queries

#### `--[no-]tuple-counting`

\[Advanced] Display tuple counts for each evaluation step in the query
evaluator logs. If the `--evaluator-log` option is provided, tuple
counts will be included in both the text-based and structured JSON logs
produced by the command. (This can be useful for performance
optimization of complex QL code).

#### `--timeout=<seconds>`

\[Advanced] Set the timeout length for query evaluation, in seconds.

The timeout feature is intended to catch cases where a complex query
would take "forever" to evaluate. It is not an effective way to limit
the total amount of time the query evaluation can take. The evaluation
will be allowed to continue as long as each separately timed part of the
computation completes within the timeout. Currently these separately
timed parts are "RA layers" of the optimized query, but that might
change in the future.

If no timeout is specified, or is given as 0, no timeout will be set
(except for [codeql test run](/code-security/codeql-cli/codeql-cli-manual/test-run), where the default timeout is 5 minutes).

#### `-j, --threads=<num>`

Use this many threads to evaluate queries.

Defaults to 1. You can pass 0 to use one thread per core on the machine,
or -_N_ to leave _N_ cores unused (except still use at least one
thread).

#### `--[no-]save-cache`

\[Advanced] Aggressively write intermediate results to the disk cache.
This takes more time and uses (much) more disk space, but may speed up
the subsequent execution of similar queries.

#### `--[no-]expect-discarded-cache`

\[Advanced] Make decisions about which predicates to evaluate, and what
to write to the disk cache, based on the assumption that the cache will
be discarded after the queries have been executed.

#### `--[no-]keep-full-cache`

\[Advanced] Don't clean up the disk cache after evaluation completes.
This may save time if you're going to do [codeql dataset cleanup](/code-security/codeql-cli/codeql-cli-manual/dataset-cleanup) or [codeql database cleanup](/code-security/codeql-cli/codeql-cli-manual/database-cleanup) afterwards anyway.

#### `--max-disk-cache=<MB>`

Set the maximum amount of space that the disk cache for intermediate
query results can use.

If this size is not configured explicitly, the evaluator will try to use
a "reasonable" amount of cache space, based on the size of the dataset
and the complexity of the queries. Explicitly setting a higher limit
than this default usage will enable additional caching which can speed
up later queries.

#### `--min-disk-free=<MB>`

\[Advanced] Set target amount of free space on file system.

If `--max-disk-cache` is not given, the evaluator will try hard to
curtail disk cache usage if the free space on the file system drops
below this value.

#### `--min-disk-free-pct=<pct>`

\[Advanced] Set target fraction of free space on file system.

If `--max-disk-cache` is not given, the evaluator will try hard to
curtail disk cache usage if the free space on the file system drops
below this percentage.

#### `--external=<pred>=<file.csv>`

A CSV file that contains rows for external predicate `<pred>`.
Multiple `--external` options can be supplied.

#### `--xterm-progress=<mode>`

\[Advanced] Controls whether to show progress tracking during QL
evaluation using xterm control sequences. Possible values are:

`no`: Never produce fancy progress; assume a dumb terminal.

`auto` _(default)_: Autodetect whether the command is running in an
appropriate terminal.

`yes`: Assume the terminal can understand xterm control sequences. The
feature still depends on being able to autodetect the _size_ of the
terminal, and will also be disabled if `-q` is given.

`25x80` (or similar): Like `yes`, and also explicitly give the size of
the terminal.

`25x80:/dev/pts/17` (or similar): show fancy progress on a _different_
terminal than stderr. Mostly useful for internal testing.

### Options for controlling outputting of structured evaluator logs

#### `--evaluator-log=<file>`

\[Advanced] Output structured logs about evaluator performance to the
given file. The format of this log file is subject to change with no
notice, but will be a stream of JSON objects separated by either two
newline characters (by default) or one if the `--evaluator-log-minify`
option is passed. Please use `codeql generate log-summary <file>` to
produce a more stable summary of this file, and avoid parsing the file
directly. The file will be overwritten if it already exists.

#### `--evaluator-log-minify`

\[Advanced] If the `--evaluator-log` option is passed, also passing
this option will minimize the size of the JSON log produced, at the
expense of making it much less human readable.

### Options for configuring the CodeQL package manager

#### `--registries-auth-stdin`

Authenticate to GitHub Enterprise Server Container registries by passing
a comma-separated list of `<registry_url>=<token>` pairs.

For example, you can pass
`https://containers.GHEHOSTNAME1/v2/=TOKEN1,https://containers.GHEHOSTNAME2/v2/=TOKEN2`
to authenticate to two GitHub Enterprise Server instances.

This overrides the CODEQL\_REGISTRIES\_AUTH and GITHUB\_TOKEN environment
variables. If you only need to authenticate to the github.com Container
registry, you can instead authenticate using the simpler
`--github-auth-stdin` option.

#### `--github-auth-stdin`

Authenticate to the github.com Container registry by passing a
github.com GitHub Apps token or personal access token via standard
input.

To authenticate to GitHub Enterprise Server Container registries, pass
`--registries-auth-stdin` or use the CODEQL\_REGISTRIES\_AUTH environment
variable.

This overrides the GITHUB\_TOKEN environment variable.

### Common options

#### `-h, --help`

Show this help text.

#### `-J=<opt>`

\[Advanced] Give option to the JVM running the command.

(Beware that options containing spaces will not be handled correctly.)

#### `-v, --verbose`

Incrementally increase the number of progress messages printed.

#### `-q, --quiet`

Incrementally decrease the number of progress messages printed.

#### `--verbosity=<level>`

\[Advanced] Explicitly set the verbosity level to one of errors,
warnings, progress, progress+, progress++, progress+++. Overrides `-v`
and `-q`.

#### `--logdir=<dir>`

\[Advanced] Write detailed logs to one or more files in the given
directory, with generated names that include timestamps and the name of
the running subcommand.

(To write a log file with a name you have full control over, instead
give `--log-to-stderr` and redirect stderr as desired.)
