1) Users at AMD leverage Perforce to create a file transfer mechanism between Windows and Linux that allows seamless transfer of files for pre-submit developer builds without complex permission or protocol setup between OSes.
2) The mechanism uses an intermediary Perforce depot to upload modified files from local machines. It then downloads the files to overlay changes for accelerated compilation and testing before official submission.
3) The file transfer mechanism includes a self-updating client that silently syncs the latest version from Perforce every use, ensuring developers always use the most recent version without manual updates.
Linux is the best-known and most-used open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer's hardware.

File Replication : High availability is a desirable feature of a good distributed file system and file replication is the primary mechanism for improving file availability. Replication is a key strategy for improving reliability, fault tolerance and availability. Therefore duplicating files on multiple machines improves availability and performance.
Replicated file : A replicated file is a file that has multiple copies, with each copy located on a separate file server. Each copy of the set of copies that comprises a replicated file is referred to as replica of the replicated file.
Replication is often confused with caching, probably because they both deal with multiple copies of data. The two concepts has the following basic differences:
A replica is associated with server, whereas a cached copy is associated with a client.
The existence of cached copy is primarily dependent on the locality in file access patterns, whereas the existence of a replica normally depends on availability and performance requirements.
Satynarayanana [1992] distinguishes a replicated copy from a cached copy by calling the first-class replicas and second-class replicas respectively

From ClearCase to Perforce Helix: Breakthroughs in Scalability at IntelPerforce
See how the Intel Security and Sensors Firmware team transitioned from IBM ClearCase to Perforce Helix with Microsoft TFS to enable robust and scalable ALM and CI with full traceability. Discover how Intel consolidated and converged 15 different development methodologies used to drive firmware projects to three single paths for all Intel platforms.
Microservices allow for extensible app architecture and a vendor-agnostic, scalable infrastructure. While microservices simplify app deployments, they come at a price: because they’re so fragmented, it is more difficult to track and manage all the independent, yet interconnected components of an app. All this information (requirements, code, test cases and results, build artifacts, and deployment blueprints) needs to live somewhere and most importantly be versioned. Using a real example and a live demonstration of Perforce Helix, Docker and Selenium, get best practices and tips for enabling a robust, scalable and extensible pipeline to support today’s modern app delivery.
Building a successful DevOps solution requires a holistic view of your development ecosystem plus solid technology that can support your organization today and in the future. Learn how to start defining your own successful DevOps solution and how to position Helix to be at the center of it all.

OSCamp Kubernetes 2024 | Zero-Touch OS-Infrastruktur für Container und Kubern...NETWAYS
In Kubernetes stellen wir Anwendungen als Instanz eines vordefinierten Container-Images bereit, dessen Eigenschaften deklarativ konfiguriert werden. Dies erleichtert die Automatisierung und Reproduzierbarkeit von Deployments, was wiederum das Betriebsrisiko verringert. Was wäre, wenn wir diese Eigenschaften auf die Serverprovisionierung ausweiten und das Betriebssystem selbst wie eine Anwendung in Kubernetes behandeln würden? Was wäre, wenn wir, anstatt Allzweck-Distributionen an unsere Bedürfnisse anzupassen, unseren Ansatz, wie ein “Cloud-Native” Betriebssystem funktionieren soll, von Grund auf überdenken würden? Unter Anwendung der gleichen Erwartungen, die wir an die Handhabung von Kubernetes-Anwendungen haben, präsentieren wir einen alternativen Ansatz für die Bereitstellung, Konfiguration und Lebenszyklusverwaltung des Betriebssystems. Mithilfe einer strikten Trennung von Betriebssystem und Anwendungen zeigen wir, wie ein wartbares, unveränderliches, imagebasiertes Betriebssystem erstellt werden kann. Und indem wir dieses Konzept erweitern, machen wir Provisionierunged problemlos und automatische Updates risikoarm. In diesem Vortrag werden wir auch einige der neuesten Entwicklungen zu Betriebssystemen behandeln und über das etablierte Konzept eines Container-Linux hinausgehen, hin zu einer Zukunft, die auf composable images Images mit systemd-sysext und einem generischen Modell für Image-baiserte Linux-Architekturen basiert.
How to Organize Game Developers With Different Planning NeedsPerforce
Different skills have different needs when it comes to planning. For a coder it may make perfect sense to plan work in two-week sprints, but for an artist, an asset may take longer than two weeks to complete.
How do you allow different skills to plan the way that works best for them? Some studios may choose to open up for flexibility – do whatever you like! But that tends to cause issues with alignment and siloes of data, resulting in loss of vision. Lost vision in the sense that it is difficult to understand, but also — and maybe more importantly — the risk of losing the vision of what the game will be.
With the right approach, however, you can avoid these obstacles. Join backlog expert Johan Karlsson to learn:
-The balance of team autonomy and alignment.
-How to use the product backlog to align the project vision.
-How to use tools to support the flexibility you need.

Regulatory Traceability: How to Maintain Compliance, Quality, and Cost Effic...Perforce
How do regulations impact your product requirements? How do you ensure that you identify all the needed requirements changes to meet these regulations?
Ideally, your regulations should live alongside your product requirements, so you can trace among each related item. Getting to that point can be quite an undertaking, however. Ultimately you want a process that:
-Saves money
-Ensures quality
-Avoids fines
If you want help achieving these goals, this webinar is for you. Watch Tom Totenberg, Senior Solutions Engineer for Helix ALM, show you:
-How to import a regulation document into Helix ALM.
-How to link to requirements.
-How to automate impact analysis from regulatory updates.
Efficient Security Development and Testing Using Dynamic and Static Code Anal...Perforce
Be sure to register for a demo, if you would like to see how Klocwork can help ensure that your code is secure, reliable, and compliant.
https://www.perforce.com/products/klocwork/live-demo
If it’s not documented, it didn’t happen.
When it comes to compliance, if you’re doing the work, you need to prove it. That means having well-documented SOPs (standard operating procedures) in place for all your regulated workflows.
It also means logging your efforts to enforce these SOPs. They show that you took appropriate action in any number of scenarios, which can be related to regulations, change requests, firing of an employee, logging an HR compliant, or anything else that needs a structured workflow.
But when do you need to do this, and how do you go about it?
In this webinar, Tom Totenberg, our Helix ALM senior solutions engineer, clarifies workflow enforcement SOPs, along with a walkthrough of how Perforce manages GDPR (General Data Protection Regulation) requests. He’ll cover:
-What are SOPs?
-Why is it important to have this documentation?
-Example: walking through our internal Perforce GDPR process.
-What to beware of.
-Building the workflow in ALM.
Branching Out: How To Automate Your Development ProcessPerforce
If you could ship 20% faster, what would it mean for your business? What could you build? Better question, what’s slowing your teams down?
Teams struggle to manage branching and merging. For bigger teams and projects, it gets even more complex. Tracking development using a flowchart, team wiki, or a white board is ineffective. And attempts to automate with complex scripting are costly to maintain.
Remove the bottlenecks and automate your development your way with Perforce Streams –– the flexible branching model in Helix Core.
Join Brad Hart, Chief Technology Officer and Brent Schiestl, Senior Product Manager for Perforce version control to learn how Streams can:
-Automate and customize development and release processes.
-Easily track and propagate changes across teams.
-Boost end user efficiency while reducing errors and conflicts.
-Support multiple teams, parallel releases, component-based development, and more.
How to Do Code Reviews at Massive Scale For DevOpsPerforce
Code review is a critical part of your build process. And when you do code review right, you can streamline your build process and achieve DevOps.
Most code review tools work great when you have a team of 10 developers. But what happens when you need to scale code review to 1,000s of developers? Many will struggle. But you don’t need to.
Join our experts Johan Karlsson and Robert Cowham for a 30-minute webinar. You’ll learn:
-The problems with scaling code review from 10s to 100s to 1,000s of developers along with other dimensions of scale (files, reviews, size).
-The solutions for dealing with all dimensions of scale.
-How to utilize Helix Swarm at massive scale.
Ready to scale code review and streamline your build process? Get started with Helix Swarm, a code review tool for Helix Core.
By now many of us have had plenty of time to clean and tidy up our homes. But have you given your product backlog and task tracking software as much attention?
To keep your digital tools organized, it is important to avoid hoarding on to inefficient processes. By removing the clutter in your product backlog, you can keep your teams focused.
It’s time to spark joy by cleaning up your planning tools!
Join Johan Karlsson — our Agile and backlog expert — to learn how to:
-Apply digital minimalism to your tracking and planning.
-Organize your work by category.
-Motivate teams by transitioning to a cleaner way of working.

Companies that track requirements, create traceability matrices, and complete audits - especially for compliance - run into many problems using only Word and Excel to accomplish these tasks.
Most notably, manual processes leave employees vulnerable to making costly mistakes and wasting valuable time.
These outdated tracking procedures rob organizations of benefiting from four keys to productivity and efficiency:
-Automation
-Collaboration
-Visibility
-Traceability
However, modern application lifecycle management (ALM) tools solve all of these problems, linking and organizing information into a single source of truth that is instantly auditable.
Gerhard Krüger, senior consultant for Helix ALM, explains how the right software supports these fundamentals, generating improvements that save time and money.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

[AMD] Novel Use of Perforce for Software Auto-updates and File Transfer
1.
MERGE 2013 THE PERFORCE CONFERENCE SAN FRANCISCO • APRIL 24−26
Abstract
Users can leverage the attributes of Perforce to create
a mechanism that allows seamless file transfer among
the multiple OSes that Perforce supports, without the
overhead of setting up different permissions and
protocols that may be proprietary to each OS. Such a
solution can be written in a single codebase, effectively
reducing maintenance overhead. The file-transfer
mechanism can then be extended to support auto-
updating client software, so users always will be
guaranteed that the locally installed applications will be
the latest version executed at run time.

Background and Motivation
The tools team in the graphics division at AMD created an in-house, end-to-end solution for
pre-submit developer builds (PSDB). This PSDB mechanism:
1) Takes a code change before it is submitted into version control,
2) Overlays the changes on the last-known-good version of a successful build,
3) Compiles these using an accelerated build farm to ensure compilation does not break, and
4) Deploys tests on the resulting build to ensure the changes are safe.
Once the changes pass the tests, the developer can submit the changes into version control.
However, two problems arise from Step 1:
Problem #1: How will the files be uploaded to the servers that run the mechanism?
Developers at AMD work on Windows®
and Linux operating systems. Different permissions and
privileges have to be set up for file transfer between these systems. Ideally, if a software client
performing the file transfer is installed locally on the user’s computer, then the source code for
this client should be compilable for all OSes (i.e., a single codebase should run on multiple
OSes) for ease of maintenance.
Also, development teams work with different version-control systems; some teams submit
code into Perforce while others use Subversion (SVN). The client should work with any
version-control system.
Problem #2: Given that a client will be installed on the developer’s computer to upload
the files, how can we ensure that the developer is running the latest version of the
client?
Software is a living document that gets updated frequently, especially when bugs are found
and features are added. Client updates can be deployed proactively (i.e., pushed) to ensure
developers use the latest version.
File Transfer
A crucial component of PSDB is a way to upload the code changes to the solution without
submitting them into revision control. This component must be both OS- and version-control
system-agnostic. AMD developers work in Windows and Linux OSes, and with Perforce depots
and SVN repositories for revision control.
First Attempt
To address these challenges, the first generation of the file-transfer mechanism had two
separate codebases (one codebase determined modified files in Perforce, and another in
SVN). The first attempt at writing this component used a remote file server with a shared
directory. However, file transfer was done differently for each OS.
In Windows, file transfer was done using Robocopy, a third-party tool used for synchronizing
files in two different locations. After the modified files were listed, this tool took the modified
files from the user’s local computer and copied them to a shared directory on the remote file
server. With the file server hosted on a Windows backend, the permission setup was
straightforward.
This was not the case in Linux. The Robocopy tool was not available for this OS, prompting a
different process. A Linux user would go through the additional preliminary steps of mounting

Environment

the remote directory as a superuser and ensuring the mount happened on login. Additional
packages needed to be installed (e.g., application wmctrl was needed for manipulating
windows management). Permissions also had to be set up correctly. To simplify the setup, a
script and installation recipe manual was written for Linux users. However, support calls
increased due to the complexity of the instructions, affecting quality of service.
The first generation of the file-transfer mechanism exposed the need for a simple workflow to
provide a better user experience: for instance, simple installation and a one-click upload. A
status bar could provide visual validation to display progress. Also, to reduce development
time, maintenance, and support, the succeeding version could be written in a single codebase
and employ the same mechanics for performing file transfer on different OSes.
Enter Perforce.
Current Version
The idea behind using Perforce as a back-end solution is to set up an intermediary “pre-
submit” Perforce depot that would house the files that users have modified. Once the files have
been “uploaded” to this Perforce depot, the PSDB solution can then “download” the files from
the depot and overlay them on the last-known-good version of a successful build. In Perforce
parlance, the modified files will be submitted to the pre-submit Perforce depot, and
synchronized by the PSDB for retrieval.
No changes are submitted to the main Perforce depot or SVN repository—all writeable actions
are done on the intermediary pre-submit Perforce depot. The intermediary depot exists only to
perform the file transfer. Use of this intermediary depot must be transparent to the user, as if
the depot didn’t exist.
Using Perforce
The following steps describe how AMD used Perforce to create the second generation of the
file-transfer mechanism.
1) Create a new workspace (clientspec) on the pre-submit depot.
A developer using Perforce as a version-control system already has an active
workspace for viewing and editing files. A new workspace is created on the pre-submit
depot with a View that is an exact duplicate of this active workspace’s View on the main
depot. Mimicking the active workspace guarantees that the files will be checked into the
correct relative locations in the pre-submit depot, no matter how convoluted the View is.
SVN does not adhere to the notion of a workspace, so files in a directory appear “as is”
in the repository (i.e., the new workspace View is wide, as in “//depot/…”). The danger
of a convoluted workspace is non-existent, and modified files in SVN can be uploaded
to the pre-submit Perforce depot as-is.
When creating the workspace on the pre-submit depot, ensure that the allwrite option is
enabled (i.e., the noallwrite option is disabled). Because this workspace is used to
submit the modified files into the pre-submit depot, these files should remain untouched
on the local computer from the main depot’s perspective. Enabling the allwrite option is
crucial because this ensures that the files are not switched to read-only after being
submitted to the pre-submit depot.

This is text for annotations in footer. Similar to footnotes treatment.
2) Create a pending changelist on the pre-submit depot using the new workspace;
populate this with the modified files.
This pending changelist will contain the modified files. The output of a p4 describe on
the description of the changelist on the main depot can be parsed to enumerate all files
that have been modified. These modified files on the main depot are then added to this
pending changelist, which will then be submitted to the pre-submit depot.
Modified files in SVN can be parsed from svn info. Other version-control systems would
have a similar command for listing modified files.
Files that have been deleted or removed (due to a rename or integrate/move) cannot be
added to this pending changelist. Instead, the description of the pending changelist will
enumerate these files. The PSDB mechanism will then remove these files from its copy
of the last-known-good in the next step, thereby accurately mimicking the modified state
on the user’s local computer.
3) Submit the pending changelist and trigger the pre-submit build.
Once the pending changelist has been submitted, the PSDB mechanism takes over.
PSDB takes a copy of the last-known-good version of the latest successful build,
overlays the added/edited files, removes the deleted/moved files as described in the
previous step, and initiates the accelerated build.
Benefits
By using Perforce as the main mechanism for transferring files from the user’s computer to the
PSDB server, a single codebase can be written that treats the Perforce command-line calls as
an API. With the codebase written in Perl, a write-once/run-on-all-OSes model is achieved.
The only per-OS task involved is packaging the Perl script into an executable for each OS.
Having Perforce as the back end means that the changelist submitted into the pre-submit
depot and its accompanying changelist description can be used as a rudimentary database for
keeping track of metadata and storage of modified files. Having a file server and separate SQL
database is not necessary.
AMD leveraged a Perforce installation that already existed at the company by simply creating a
new depot. We take advantage of the robustness inherent with Perforce, and merely extend its
application by piggybacking on an existing framework.
Another benefit is eliminating race conditions; when accessing the back end for uploading files,
each transaction—the Perforce submit—is atomic. Unlike FTP and rsync, this also makes
handling error conditions in the script simpler and more reliable than using an alternate data
store.
Shortcomings
By design, uploading modified files into the PSDB system can be done only through a
numbered pending changelist. This can be modified to use a default pending changelist (i.e.,
unnumbered), but numbered changelists force users to adhere to best practices.
The pre-submit depot can be filled quickly with PSDB requests. On a normal file server,
cleanups can be done easily by deleting older files. When using Perforce as an intermediary
depot, a p4 obliterate would be necessary to conserve space on the server. Maintenance
overhead can be reduced by having the obliterate command called when the server is not busy

and automated on a schedule.
Doing a PSDB request on a virtual integration is not possible because the modified files will
exist only on the main server, and not locally on the user’s computer. If a PSDB request is
necessary in this scenario, users are asked to perform the integration locally. (The actual
submission, if the PSDB tests pass, can be performed virtually.)
Given this, using a version control system as a file storage solution is overkill because
Perforce is used as an intelligent file server. However, the need to maintain a separate
database and dumb file server is removed, making this solution practical and efficient.
To implement this solution, an executable client that initiates this mechanism (i.e., the file
upload action) must be installed on the user’s local computer. Ensuring that the user has the
latest version of this client may be an issue. This is addressed in the next section.
Self Auto-Update
Software is a living document that gets updated frequently as bugs are fixed and features
added. Ideally, all users would be running the same latest version to have the best experience;
users benefit by having access to the newest features and fixes, and this also reduces
maintenance work because developers do not spend time debugging legacy versions.
However, deployment may be a necessary overhead because this requires the developer to
properly package the software (e.g., create the installer), make this available to users (i.e.,
announce and publish), and enforce (i.e., nag users) to ensure that users install the latest
version.
Web apps are not susceptible to this shortcoming. However, web apps have limitations if a
desired function can be executed only as a binary running on a local user’s computer (such as
uploading multiple files in the background — modern web browsers do not allow this because
it presents a security hole). In the case of the file-upload client, creating this client as a web
app was not an option.
The rationale behind a self auto-updating mechanism is to provide a seamless experience in
which the user is not required to perform any manual actions and is assured that the latest
version of the binary always is executed at run time.
Components
The self auto-updating mechanism consists of three entities: (1) a centralized version control
system, (2) the “caller” program installed on the user’s local computer, and (3) the “client” files
that are updated, also installed on the user’s local computer.
The centralized version control system is a file repository that tracks users’ files and their
revisions. Typically, the file repository is used for revision control: users check out files for
editing and check in files with the desired modifications. The file repository keeps track of
which files the users have on their computers, and at which revision. The file repository runs
on a server accessible to users running different OSes across the network. In our case, we
leveraged an existing Perforce implementation.
The caller is one part of the software application installed by the user manually. The caller is
not automatically updated. The caller consists of a Perforce command-line client and an
executable that calls the Perforce client with the necessary commands to perform the auto-

update.
The client files make up the rest of the software application installed by the user. These files
are the core of the installed software and handle the file upload functionality. This portion of the
software application can be updated on the user’s local computer when necessary.
Workflow
This section describes the workflow that Figure 1 illustrates.
1) Initially, the user installs the deployed software package from the author. On the local
user’s computer, the caller and client files are installed. When the user executes the
software application, the caller executable is first run in the background.
2) In the background, unknown to the user, the caller executable connects to Perforce
(using the Perforce command-line client) and creates a workspace for the user.
3) With this workspace, the caller synchronizes the client files from the Perforce server.
This action effectively overwrites the user’s local copy, thus assuring that the user’s
local copy is the latest version. When the sync is complete, the caller runs the client.
The client is essentially the core of the software, and is the portion that is updated and
executed.
Every time the user runs the software, the caller synchronizes with the Perforce server.
If all files are up to date, no action is necessary and the installed application (i.e., the
client) runs as usual.
4) When a new revision of the software is ready, the author checks in the modified client
files to the file repository. No further action is required from the author.
5) If the user runs the installed software after the update, the caller connects to Perforce
and detects that the client files on the user’s local computer are not up to date through
p4 sync.
6) The same p4 sync call grabs the latest version of the client files. After the sync, the
updated version of the client files—now the latest—is executed.

Benefits
This method leverages the existing Perforce set up. A separate database or file server is not
necessary.
Whenever users initiate the file upload from their local computers (regardless of using Perforce
or SVN as their main repository), the caller ensures that the latest client is always
synchronized locally and executed. This happens entirely in the background, silently, and
users are not required to perform any explicit actions to update their local copy of the client.
The version number is logged on the submit changelist in the intermediary Perforce depot
each time the file upload is performed. Auditing these version numbers can verify that the auto-
update mechanism is working and that the user is running the latest version.
To verify initially that the auto-update mechanism is working, the package used for the first
installation contains a client that is one version behind. When the user runs the installer for the
first time, the auto-update mechanism engages and retrieves the latest version from the

Perforce server. The version number is then logged and inspected. If the version number is not
the latest, contact is initiated with the user to debug the issue. This proactive measure
improves the quality of service provided to users of the application.
Shortcomings
The full package initially installed by the user is not updated automatically; only the client files
are updated silently. This is sufficient for deploying features and bug fixes that affect file-
upload functionality.
If a full application upgrade is required (i.e., the caller needs to be updated), then the original
manner of deployment (i.e., packaging/publishing/enforcing) is pursued. However, this is
performed rarely because the caller portion of the software application has matured.
The caller currently consists of a separate Perforce command-line client and the executable
that calls the Perforce client. The executable calls the Perforce commands through the shell.
The executable can be rewritten to take advantage of existing Perforce APIs instead
Walk-through
The caller and client scripts are written in Perl and converted into executable binaries using
ActivePerl for Windows (32-bit) and Linux (Ubuntu 32-bit and 64-bit). The Windows 32-bit
executable can be used on 64-bit versions of Windows. These binaries are then packaged
using InstallShield (for Windows) or tarballed (Linux) and uploaded to a server, ready for
download.
The user downloads the package and runs the installer. The installer takes care of adding the
caller to the list of Custom Tools (see Figure 2). An install script written for Linux users
performs this task.
Figure 2: The caller added to the list of Custom Tools in P4V
The file-upload mechanism can be initiated by right-clicking a numbered pending changelist in
P4V for Perforce users (see Figure 3). In SVN, right-clicking a folder in Windows Explorer
presents this option. The file-upload mechanism also can be initiated from the command line.

Figure 3: Calling the file uploader mechanism from P4V
The caller validates all parameters and synchronizes the client. Figure 4 shows the client as up
to date, ensuring that the user is running the latest version. The caller then runs the client to
perform the file upload.
Figure 4: The log shows the caller running p4 sync; the client is at the latest version
The client parses the pending changelist using p4 describe and lists the files. A workspace
mimicking the user’s local workspace is created on the intermediary Perforce depot, and a
pending changelist is created. Added/modified files are included in this pending changelist.
Deleted/renamed/moved files are noted in the changelist description and will be removed from
the PSDB copy. Figure 5 shows these steps.

The pending changelist is then submitted to the intermediary Perforce depot. Once this has

For simplicity, the user sees only a progress bar and status to demonstrate the stages of the
file upload during this time (see Figure 7). The user has the option to view the log if desired;
the log also appears when an error occurs. The user can then send the log to the PSDB team
for debugging.

Conclusion
This white paper describes an unintended use of Perforce to perform file transfers by
leveraging Perforce as an intelligent file storage server. Although this may be overkill for a
version-control system and other file transfer protocols such as FTP or SCP could have been
used, this novel method removes the overhead of setting up and maintaining a separate
database to manage the files that have to be transferred.
By taking advantage of Perforce’s robustness and its consistency of command calls being
supported on different operating systems, the described method can be applied without having
to maintain different codebases and set-up procedures for each OS.
The file transfer method is then extended into a self auto-updating mechanism to ensure that
users have the latest version of software installed on their local computers.
