Description
When a file has been opened by p4
add
, p4
edit
, p4
delete
, or p4
integrate
, the file is listed in a
changelist
. The user’s changes to the file are made
only within the client workspace copy until the changelist is sent to the
depot with p4 submit
.
In addition to the files being submitted, any open stream specification
is also submitted. To submit only files and not an open stream spec, see streams and p4 submit. For more information on open stream
specifications, see p4
stream
.
By default, files are opened within the default changelist, but you can
also create new numbered changelists with p4 change
.
- To submit the default changelist, use
p4 submit
. -
To submit a numbered changelist, use
p4 submit -c changelist
.Using the
-c
option also allows you to change the description information for a numbered changelist.
By default, all files in the changelist are submitted to the depot, and
files open for edit
, add
, and
branch
are closed when submitted, whether there are any
changes to the files or not. To change this default behavior, set the
SubmitOptions
field in the p4 client
form for your
workspace. To override your workspace’s SubmitOptions:
setting from the command line, use p4 submit -f
submitoption
.
When used with the default changelist, p4 submit
brings up a form for editing in the editor defined by the
EDITOR
(or P4EDITOR
) environment variable.
Files can be deleted from the changelist by deleting them from the form,
but these files will remain open in the next default changelist. To close
a file and remove it from all changelists, use p4 revert
.
All changelists have a Status
field. The value of this
field is pending
or submitted
:
- Submitted
changelists have been successfully submitted with
p4 submit
. - Pending changelists have been created by the user but not yet been submitted successfully.
To supply a changelist description from the command line, use the
-d
option. No change description dialog is presented. The
-d
option works only with the default changelist, not with
numbered changelists.
A file’s location in the depot is determined by its location in the
local filesystem and by the client workspace definition, which is
specified in the p4
client
form. See the "Configure clients" chapter in the
Helix Core Command-Line (P4) Guide.
Submit processing
p4 submit works atomically: either all the files
listed in the changelist are saved in the depot, or none of them are. The
atomic nature of p4 submit
allows files to be grouped
in a changelists according to their purpose. For example, a single
changelist might contain changes to three files that fix a single bug.
p4 submit
fails if it is interrupted, or if any of
the files in the changelist are not found in the current client
workspace, are locked in another client workspace (with p4 lock
), or require
resolution and remain unresolved.
A progress indicator is available for p4 submit
if
you request it with p4 -I submit
.
Before committing a changelist, p4 submit
briefly
locks all files being submitted. If any file cannot be locked or
submitted, the files are left open in a numbered pending changelist. By
default, the files in a failed submit operation are left locked unless
the submit.unlocklocked
configurable is set. If submit.unlocklocked
is set, files are
unlocked even if they were manually locked prior to submit if submit
fails.
If p4 submit
fails while processing the default
changelist, the changelist is assigned the next number in the changelist
sequence, and the default changelist is emptied. The changelist that
failed submission must be resubmitted by number after the problems are
fixed.
If p4 submit
fails, some or all of the files might
have been copied to the server. By default, retrying a failed submit
transfers all these files again unless the
submit.noretransfer
configurable is set, in which case the
server attempts to detect if the files have already been transferred and
does not re-transfer all files when retrying a failed submit. You can use
the --noretransfer
option to override the
submit.noretransfer
configurable and allow the user to
choose the preferred re-transfer behavior for the current submit
operation.
Parallel submits
You can transfer files in parallel during the submit process. If there are sufficient resources, a submit command might execute more rapidly by transferring multiple files in parallel. For this feature to work, you must have both server and client upgraded to version 2015.2 or later. Read this section in its entirety to make sure that you are using this feature appropriately.
To enable parallel submits, set the net.parallel.max
configurable to a value greater than 1
. (See also Automatic parallel submits.)
-
Specify
threads=
to request that files be sent concurrently using the specified number of independent network connections. The threads grab work in batches.N
-
You can specify
batch=
to control the number of files in a batch.N
-
You can specify the
min
option to control the minimum number of files in a parallel submit.
If the
net.parallel.max
configuration variable is not set, the command executes without using parallel threads.If the requested number of parallel threads exceeds the value set for
net.parallel.max
, the command uses the maximum number of allowed threads. -
-
Parallel submits from an edge server to a commit server use standard pull threads to transfer the files. The administrator must ensure that pull threads can be run on the commit server by doing the following:
- Make sure that the service user used by the commit server is logged into the edge server.
-
Make sure the
ExternalAddress
field of the edge server’s server spec is set to the address that will be used by the commit server’s pull threads to connect to the edge server.If the commit and edge servers communicate on a network separate from the network used by clients to communicate with the edge server, the
ExternalAddress
field must specify the edge server ip address and port number that is used for connections from the commit server. Furthermore, the edge server must listen on the two (or more) networks.ImportantLimitation: Parallel submit is not supported from an edge server if the commit server is on a Windows platform. In this case --parallel or automatic parallel processing for submit will be silently ignored, and the submit will run without using parallel threads.
-
The
--parallel
option is ignored when the archives are shared, forp4 submit -e
, and when progress indicators are used.Automatic parallel submits
To enable automatic parallel processing for p4 submit, set non-zero values for both configurables: net.parallel.max and net.parallel.submit.threads. For example:
p4 configure set net.parallel.max=50
p4 configure set net.parallel.submit.threads=3
If automatic parallel processing is enabled, the following configurables no longer have the default value of
0
:Configurable New value Description net.parallel.batch 8 for p4 sync, the number of files in a batch net.parallel.batchsize 512 KB for p4 sync, the number of bytes in a batch net.parallel.min 9 for p4 sync, the mininum number of files in a batch net.parallel.minsize 576 KB for p4 sync, the minimum of bytes in a parallel sync net.parallel.submit.batch 8 for p4 submit, number of files in a batch net.parallel.submit.min 9 for p4 submit, mininum number of files in a batch In this case, you can use any of the syntax variants for the
p4 submit
command (without specifying the--parallel
option) and processing will be automatically done in parallel.- If you do use the
--parallel
option explicitly and you have thenet.parallel.*
configurables set, the configurable values you specify on the command line override the value of the configurables. - You can turn off automatic parallel submit by unsetting the
net.parallel.submit.threads
configurable. - You can disable the parallel submit configurable settings by
specifying
p4 submit --parallel=0
.
- If you do use the
Performance and parallel submits
Using parallel submits improves performance in cases like the following:
-
Significant network latency exists somewhere along the path through which the submitted file content travels from the client to the repository where the file content is stored.
This includes significant network latency between a Proxy and Server, or between an Edge Server and a Commit Server. When using parallel submit in such a configuration, the inherent TCP delays related to network latency occur concurrently, rather than sequentially when not using parallel submit.
-
Significant resources are required during the transfer of the submitted file, and those resources are available.
For example, if significant CPU cycles are required to compress ctext or binary file content as it is transferred from a client to a server, the compression of the file content can occur on one CPU core per parallel submit thread compressing either a ctext or binary file, so long as there are enough available CPU cores.
In other cases, using parallel submit might not result in significant performance benefits:
-
In some environments, network bandwidth can be a precious resource.
If network latency is minimal, it might not take many parallel submit threads to use the available network bandwidth. Once the available network bandwidth is used, adding parallel submit threads might not improve performance. This is especially true when transferring file content for which only network bandwidth resources are needed, such as when transferring ubinary files.
-
Using a small value for the
batch
andmin
arguments specified with the--parallel
option is only practical in some cases.For example, if a small number of large ctext or binary files are submitted using parallel submit, transferring a small number of files per parallel submit thread can result in the best performance, provided that adequate CPU and network bandwidth resources are available. For parallel submit to transfer an evenly-distributed number of files over the number of parallel submit threads specified (which defaults to
4
), thebatch
argument might need to be set to a value lower than its default of8
.-
For example, if submitting eight large ctext or binary files using four parallel submit threads, the
batch
argument should be set to two. The value for themin
argument, which defaults to9
, should be set to less than or equal to the number of large ctext or binary files being submitted. -
On the other hand, using a small value for the
batch
argument can degrade performance when submitting many small files using parallel submit. In such a case, the overhead of the server frequently querying thedb.sendq
table for each batch by each parallel submit thread can result indb.sendq
concurrency issues.

About background archive transfer for edge server submits
This feature is designed to reduce the amount of wait time end-users perceive when submitting files.
The -b option of the p4 submit command can be used on an edge server to enable the edge archive to be transferred to the commit server in the background. The submit process on the commit server schedules the transfers and completes the submit without the end user waiting for transfers to finish. The archives on the originating edge server are transferred to the commit server by pull threads initiated by submit on the commit server.
Submitting pending (not shelved) changes using the -b option causes any change-submit triggers to be fired before edge-content triggers. To learn more, see Triggers and commit-edge. An administrator must ensure that pull threads can be run on the commit server. The edge server IP address and port number used by the commit server to connect to the edge server must be specified in the ExternalAddress: field of the edge server spec. To learn more, see Background archive transfer for edge server submits in the Helix Core Server Administrator Guide.
Limitations
-
If the administrator has not enabled background submit, the -b option is ignored and standard submit behavior occurs.
- Archives of ktext files are transferred serially because archive content depends on commit server work.
- This feature does not support graph depots.
-
Background archive transfer is incompatible with:
-
the command-line --noretransfer option
- the submit.noretransfer configurable
-
streams and p4 submit
By default, an open stream spec is submitted with the files.
When the default changelist is submitted, the -So
and -Sx
options control whether an open stream spec is included.
-
To submit only the open stream spec, use
-So
with no file list. -
To exclude the open stream spec when submitting some of the files, use
-Sx
with a file list. -
To exclude the open stream spec when submitting all of the files, use
-Sx
with no file list.
To learn more, see Examples for submitting streams.
