Using Creative Commons Public Licenses
Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.
Considerations for licensors: Our public licenses are
intended for use by those authorized to give the public
permission to use material in ways otherwise restricted by
copyright and certain other rights. Our licenses are
irrevocable. Licensors should read and understand the terms
and conditions of the license they choose before applying it.
Licensors should also secure all rights necessary before
applying our licenses so that the public can reuse the
material as expected. Licensors should clearly mark any
material not subject to the license. This includes other CC-
licensed material, or material used under an exception or
limitation to copyright. More considerations for licensors:

Considerations for the public: By using one of our public
licenses, a licensor grants the public permission to use the
licensed material under specified terms and conditions. If
the licensor's permission is not necessary for any reason--for
example, because of any applicable exception or limitation to
copyright--then that use is not regulated by the license. Our
licenses grant only permissions under copyright and certain
other rights that a licensor has authority to grant. Use of
the licensed material may still be restricted for other
reasons, including because others have copyright or other
rights in the material. A licensor may make special requests,
such as asking that all changes be marked or described.
Although not required by our licenses, you are encouraged to
respect those requests where reasonable. More considerations

Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International
Public License
By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-NonCommercial-ShareAlike 4.0 International Public License
("Public License"). To the extent this Public License may be
interpreted as a contract, You are granted the Licensed Rights in
consideration of Your acceptance of these terms and conditions, and the
Licensor grants You such rights in consideration of benefits the
Licensor receives from making the Licensed Material available under
these terms and conditions.
Section 1 -- Definitions.
a. Adapted Material means material subject to Copyright and Similar
Rights that is derived from or based upon the Licensed Material
and in which the Licensed Material is translated, altered,
arranged, transformed, or otherwise modified in a manner requiring
permission under the Copyright and Similar Rights held by the
Licensor. For purposes of this Public License, where the Licensed
Material is a musical work, performance, or sound recording,
Adapted Material is always produced where the Licensed Material is
synched in timed relation with a moving image.
b. Adapter's License means the license You apply to Your Copyright
and Similar Rights in Your contributions to Adapted Material in
accordance with the terms and conditions of this Public License.
c. BY-NC-SA Compatible License means a license listed at
creativecommons.org/compatiblelicenses, approved by Creative
Commons as essentially the equivalent of this Public License.
d. Copyright and Similar Rights means copyright and/or similar rights
closely related to copyright including, without limitation,
performance, broadcast, sound recording, and Sui Generis Database
Rights, without regard to how the rights are labeled or
categorized. For purposes of this Public License, the rights
specified in Section 2(b)(1)-(2) are not Copyright and Similar
Rights.
e. Effective Technological Measures means those measures that, in the
absence of proper authority, may not be circumvented under laws
fulfilling obligations under Article 11 of the WIPO Copyright
Treaty adopted on December 20, 1996, and/or similar international
agreements.
f. Exceptions and Limitations means fair use, fair dealing, and/or
any other exception or limitation to Copyright and Similar Rights
that applies to Your use of the Licensed Material.
g. License Elements means the license attributes listed in the name
of a Creative Commons Public License. The License Elements of this
Public License are Attribution, NonCommercial, and ShareAlike.
h. Licensed Material means the artistic or literary work, database,
or other material to which the Licensor applied this Public
License.
i. Licensed Rights means the rights granted to You subject to the
terms and conditions of this Public License, which are limited to
all Copyright and Similar Rights that apply to Your use of the
Licensed Material and that the Licensor has authority to license.
j. Licensor means the individual(s) or entity(ies) granting rights
under this Public License.
k. NonCommercial means not primarily intended for or directed towards
commercial advantage or monetary compensation. For purposes of
this Public License, the exchange of the Licensed Material for
other material subject to Copyright and Similar Rights by digital
file-sharing or similar means is NonCommercial provided there is
no payment of monetary compensation in connection with the
exchange.
l. Share means to provide material to the public by any means or
process that requires permission under the Licensed Rights, such
as reproduction, public display, public performance, distribution,
dissemination, communication, or importation, and to make material
available to the public including in ways that members of the
public may access the material from a place and at a time
individually chosen by them.
m. Sui Generis Database Rights means rights other than copyright
resulting from Directive 96/9/EC of the European Parliament and of
the Council of 11 March 1996 on the legal protection of databases,
as amended and/or succeeded, as well as other essentially
equivalent rights anywhere in the world.
n. You means the individual or entity exercising the Licensed Rights
under this Public License. Your has a corresponding meaning.
Section 2 -- Scope.
a. License grant.
1. Subject to the terms and conditions of this Public License,
the Licensor hereby grants You a worldwide, royalty-free,
non-sublicensable, non-exclusive, irrevocable license to
exercise the Licensed Rights in the Licensed Material to:
a. reproduce and Share the Licensed Material, in whole or
in part, for NonCommercial purposes only; and
b. produce, reproduce, and Share Adapted Material for
NonCommercial purposes only.
2. Exceptions and Limitations. For the avoidance of doubt, where
Exceptions and Limitations apply to Your use, this Public
License does not apply, and You do not need to comply with
its terms and conditions.
3. Term. The term of this Public License is specified in Section
6(a).
4. Media and formats; technical modifications allowed. The
Licensor authorizes You to exercise the Licensed Rights in
all media and formats whether now known or hereafter created,
and to make technical modifications necessary to do so. The
Licensor waives and/or agrees not to assert any right or
authority to forbid You from making technical modifications
necessary to exercise the Licensed Rights, including
technical modifications necessary to circumvent Effective
Technological Measures. For purposes of this Public License,
simply making modifications authorized by this Section 2(a)
(4) never produces Adapted Material.
5. Downstream recipients.
a. Offer from the Licensor -- Licensed Material. Every
recipient of the Licensed Material automatically
receives an offer from the Licensor to exercise the
Licensed Rights under the terms and conditions of this
Public License.
b. Additional offer from the Licensor -- Adapted Material.
Every recipient of Adapted Material from You
automatically receives an offer from the Licensor to
exercise the Licensed Rights in the Adapted Material
under the conditions of the Adapter's License You apply.
c. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the Licensed
Material.
6. No endorsement. Nothing in this Public License constitutes or
may be construed as permission to assert or imply that You
are, or that Your use of the Licensed Material is, connected
with, or sponsored, endorsed, or granted official status by,
the Licensor or others designated to receive attribution as
provided in Section 3(a)(1)(A)(i).
b. Other rights.
1. Moral rights, such as the right of integrity, are not
licensed under this Public License, nor are publicity,
privacy, and/or other similar personality rights; however, to
the extent possible, the Licensor waives and/or agrees not to
assert any such rights held by the Licensor to the limited
extent necessary to allow You to exercise the Licensed
Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this
Public License.
3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties, including when
the Licensed Material is used other than for NonCommercial
purposes.
Section 3 -- License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the
following conditions.
a. Attribution.
1. If You Share the Licensed Material (including in modified
form), You must:
a. retain the following if it is supplied by the Licensor
with the Licensed Material:
i. identification of the creator(s) of the Licensed
Material and any others designated to receive
attribution, in any reasonable manner requested by
the Licensor (including by pseudonym if
designated);
ii. a copyright notice;
iii. a notice that refers to this Public License;
iv. a notice that refers to the disclaimer of
warranties;
v. a URI or hyperlink to the Licensed Material to the
extent reasonably practicable;
b. indicate if You modified the Licensed Material and
retain an indication of any previous modifications; and
c. indicate the Licensed Material is licensed under this
Public License, and include the text of, or the URI or
hyperlink to, this Public License.
2. You may satisfy the conditions in Section 3(a)(1) in any
reasonable manner based on the medium, means, and context in
which You Share the Licensed Material. For example, it may be
reasonable to satisfy the conditions by providing a URI or
hyperlink to a resource that includes the required
information.
3. If requested by the Licensor, You must remove any of the
information required by Section 3(a)(1)(A) to the extent
reasonably practicable.
b. ShareAlike.
In addition to the conditions in Section 3(a), if You Share
Adapted Material You produce, the following conditions also apply.
1. The Adapter's License You apply must be a Creative Commons
license with the same License Elements, this version or
later, or a BY-NC-SA Compatible License.
2. You must include the text of, or the URI or hyperlink to, the
Adapter's License You apply. You may satisfy this condition
in any reasonable manner based on the medium, means, and
context in which You Share Adapted Material.
3. You may not offer or impose any additional or different terms
or conditions on, or apply any Effective Technological
Measures to, Adapted Material that restrict exercise of the
rights granted under the Adapter's License You apply.
Section 4 -- Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database for NonCommercial purposes
only;
b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database
Rights (but not its individual contents) is Adapted Material,
including for purposes of Section 3(b); and
c. You must comply with the conditions in Section 3(a) if You Share
all or a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.
Section 5 -- Disclaimer of Warranties and Limitation of Liability.
a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,

# SEGA Lindbergh Emulator
This project emulates the SEGA Lindbergh, allowing games to run on modern Linux computers with an NVIDIA graphics card to be used as replacement hardware for broken Lindbergh systems in physical arcade machines.
You can view the supported titles [here.](docs/supported.md)
## Dependencies
First make sure you have up-to-date NVIDIA drivers and then install the following:
```
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install gcc-multilib
sudo apt install build-essential
sudo apt install freeglut3:i386
sudo apt install freeglut3-dev:i386
sudo apt install libglew-dev
sudo apt install xorg-dev
sudo apt install libopenal1:i386 libopenal-dev:i386
sudo apt install libalut-dev:i386 // You will need to find libalut-dev:i386, libalut0:i386 and multiarch-support:i386 from Ubuntu Xenial.
sudo apt install libxmu6:i386
sudo apt install libstdc++5:i386
sudo apt install libasound2-dev:i386
```
For Ubuntu 22.04 and above you'll need to download manually from Xenial.
```
wget -q http://launchpadlibrarian.net/534757982/multiarch-support_2.23-0ubuntu11.3_i386.deb \
&& dpkg -i multiarch-support_2.23-0ubuntu11.3_i386.deb
wget -q http://launchpadlibrarian.net/184146495/libalut0_1.1.0-5_i386.deb \
&& dpkg -i libalut0_1.1.0-5_i386.deb
wget -q http://launchpadlibrarian.net/184146496/libalut-dev_1.1.0-5_i386.deb \
&& dpkg -i libalut-dev_1.1.0-5_i386.deb
```
Note: The project has been tested to work on Ubuntu 22.04, and doesn't currently work on Ubuntu 23.10. Multiple packages such as `freeglut3:i386` are not available anymore on Debian Trixxie or Ubuntu 23.10.
This project emulates the SEGA Lindbergh, allowing games to run on modern Linux computers to be used as replacement hardware for broken Lindbergh systems in physical arcade machines. It supports both Intel and AMD CPUs as well as Intel, NVIDIA and AMD GPUs, surround sound audio, networking and JVS pass through.
## Building & Running
This emulator will need access to the input devices and serial devices on Linux. Before running this emulator you should add your user account to the following groups and then _restart your computer_.
First you will need to install the following dependencies.
```shell
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install git build-essential gcc-multilib freeglut3-dev:i386 libsdl2-dev:i386 libfaudio-dev:i386
```
This emulator will need access to the input devices and serial devices on your computer. You should add your user account to the following groups and then _restart your computer_.
```shell
sudo usermod -a -G dialout,input $USER
```
To build, run the makefile, and then copy the contents of the build directory into the game directory and run.
Then you should clone the repository, change directory into it and run make.
```
```shell
git clone git@github.com:dkeruza-neo/lindbergh-loader.git
cd lindbergh-loader
make
cp build/* ~/the-house-of-the-dead-4/disk0/elf/.
cd ~/the-house-of-the-dead-4/disk0/elf
```
You should then copy the contents of the build directory to your game directory and run `./lindbergh` for the game, or `./lindbergh -t` for test mode.
```shell
cp -a build/* /home/games/the-house-of-the-dead-4/disk0/elf/.
cd /home/games/the-house-of-the-dead-4/disk0/elf/.
./lindbergh
```
Some games will require extra libraries like `libposixtime.so`, which can be found in dumps of the Lindbergh CF image.
If you'd like to change game settings copy the default configuration file from the repository to your game directory.
A default configuration file is provided in `docs/lindbergh.conf`. It should be placed in the same folder the game is run from. If no config file is present a default setting will be used.
```shell
cp build/docs/lindbergh.conf /home/games/the-house-of-the-dead-4/disk0/elf/.
nano lindbergh.conf
```
Do not run this as root, instead use the usergroups for input/dialout to give the emulator access to what it needs. Lindbergh games expect full control of the Linux OS and with root privilages it is possible that they could cause damage to your computer.
Configuration options and supported games are explained in the [guide](docs/guide.md).
A `lindbergh` executable is provided in the build directory to easily run the games. Place it in the same directory as the game elf, and run `./lindbergh` to automatically start the game with the correct environment variables set, or run `./lindbergh -t` for test mode.

# Guide
All configurable options are set and explained in the `lindbergh.conf` file, and should be resonably easy to understand. This document further explains some of those setup options.
## Controller Setup
There are 2 modes for the controller setup in the emulator, these are set using the `INPUT_MODE` flag in the configuration file.
### Input Mode 0
In this input mode, both input mode 1 and input mode 2 are active.
### Input Mode 1
In the first input mode, the keys on the keyboard are used to control the game play. If playing a light gun game, the mouse pointer in the window is used as the player 1 light gun. There are no configurable options in this mode.
### Input Mode 2
In the second input mode, inputs are taken directly from the evdev library in linux and so you can configure additional devices such as light guns, controllers and steering wheels.
To list the available inputs you should type:
```
./lindbergh --lits-inputs
```
From there you will be able to see the controllers and all of the inputs support. Then in the config file you should map an arcade input to a controller input as follows.
```
PLAYER_1_BUTTON_UP XBOX_CONTROLLER_BTN_UP
ANALOGUE_1 XBOX_CONTROLLER_ABS_X
```
You can map digital controls to analogue controls. The analogue value will be set to the digital value, such that if the button isn't pressed it will be set to 0, and if the button is pressed it will be set to MAX. This is useful if your controller doesn't have analogue accelerator or break buttons.
```
ANALOGUE_0 XBOX_CONTROLLER_BUTTON_BR
```
You can map analogue controls to digital controls too. For each analogue input, there are 2 more inputs created ending in _MAX and _MIN. These are digital controls that will be triggered when the analogue input is either at the minimum or maximum value. This can be useful if you'd like to use an analogue stick to control a fighting game for example.
```
PLAYER_1_BUTTON_UP XBOX_CONTROLLER_ABS_Y_MAX
PLAYER_1_BUTTON_DOWN XBOX_CONTROLLER_ABS_Y_MIN
PLAYER_1_BUTTON_LEFT XBOX_CONTROLLER_ABS_X_MIN
PLAYER_1_BUTTON_RIGHT XBOX_CONTROLLER_ABS_X_MAX
```
## Audio
There are currently no audio options that you can set. If you have a stereo sound card installed then the audio will be downmixed to stereo. If you have a 5.1 sound card installed and the game supports surround sound, each surround channel should be passed through properly and should play sound as it was originally intended.
## Supported Games
The follow list of games are supported. It is worth noting that there are multiple releases of these games, and some specific releases may not be supported.

## Games that work
These games have been loaded at some point using this software, but this doesn't mean they currently work or there are instructions on how to get them running.
Working is defined by getting into attract mode and running the game, but not necessarily controlling it.

# Windows Installation Instructions
Please note that this software is still in the alpha phase, and it's very unlikely any games will be fully playable.
## Requirements
- Windows 10 build 2004 or higher
- WSL2
- Ubuntu 22.04
## Building & Installation
Launch Ubuntu 22.04 and and reset the root password.
```
sudo passwd root
su root
```
Now that you're in the root user you can install the dependencies:
```
sudo dpkg --add-architecture i386
sudo apt update && apt list --upgradable && apt upgrade
sudo apt install wsl g++ mesa-utils cmake make-guile gcc-multilib xorg-dev libxmu6:i386 libstdc++5:i386 libopenal-dev:i386 freeglut3:i386 freeglut3-dev:i386 libglew-dev
```
Now you will need to build libalut (the audio library) from source:
```
git clone --recursive https://github.com/vancegroup/freealut.git
cd freealut
cmake . -DCMAKE_INSTALL_PREFIX:STRING="/usr" -DCMAKE_C_FLAGS:STRING="-m32 -O2"
make
make install
```
Now you should add yourself to the following groups.
```
sudo addgroup $USER dialout
sudo addgroup $USER input
```
Now you can clone and build the lindbergh loader repository.
```
cd
git clone https://github.com/bobbydilley/lindbergh-loader.git
cd lindbergh-loader
make
```
You should then see the 3 .so files produced in the `build` directory.
## Launching a game
You should copy the 3 files from the `lindbergh-loader/build` directory to the directory with the game elf in.
Then open powershell in windows and do the following steps.
```
cd C:\rom\hod4\elf
bash
cp ~/lindbergh-loader/build/* .
LD_PRELOAD=lindbergh.so LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. ./hod4M.elf
```
## Thanks
Thanks to dorminirko for the testing and writing of the original guide.

Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script). Here is a another example:
/bin/bash ./configure CONFIG_SHELL=/bin/bash
Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
configuration-related scripts to be executed by `/bin/bash'.
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

## dummy dependencies for each header file. Too bad gcc doesn't do

The <b>LibXDiff</b> library implements basic and yet complete
functionalities to create file differences/patches to both binary and
text files. The library uses memory files as file abstraction to
achieve
both performance and portability. For binary files, <b>LibXDiff</b>
implements both (with some modification) the algorithm described in <i>File
System Support for Delta Compression</i> by <i>Joshua P. MacDonald</i>,
and the algorithm described in <span style="font-style: italic;">Fingerprinting
By Random Polynomials</span> by <span style="font-style: italic;">Michael
O. Rabin</span>. While for text files it follows directives described
in <i>An O(ND)
Difference Algorithm and Its Variations</i> by <i>Eugene W. Myers</i>.
Memory files used by the library are basically a collection of buffers
that store the file content. There are two different requirements for
memory files when passed to diff/patch functions. Text files for
diff/patch functions require that a single line do not have to spawn
across two different memory file blocks. Binary diff/patch functions
require memory files to be compact. A compact memory files is a file
whose content is stored inside a single block. Functionalities inside
the library are available to satisfy these rules. Using the <b>XDL_MMF_ATOMIC</b>
memory file flag it is possible to make writes to not split the written
record across different blocks, while the functions <b>xdl_mmfile_iscompact</b>()
, <b>xdl_mmfile_compact</b>() and <b>xdl_mmfile_writeallocate</b>()
are usefull to test if the file is compact and to create a compacted
version of the file itself. The text file differential output uses the
raw unified output format, by omitting the file header since the result
is always relative to a single compare operation (between two files).
The output format of the binary patch file is proprietary (and binary)
and it is basically a collection of copy and insert commands, like
described inside the MacDonald paper. The library is compatible with
almost every Unix implementation (configure script) and it is also
compatible with Windows through custom (nmake) make files. Examples are
available inside the <span style="font-style: italic;">test</span>
subdirectory of the distribution tarball that show how to use the
library. Also, inside the same subdirectory, a regression test in
available that tests the library with random data by requiring a diff
followed by a patch and comparing results. Regression tests ran
successfully for days on my Linux, Solaris, FreeBSD and Windows boxes,
and this makes me believe that the library itself is completely ready
for production (despite the version number).<br>

.SH DESCRIPTION
The
.B LibXDiff
library implements basic and yet complete functionalities to create
file differences/patches to both binary and text files. The library
uses memory files as file abstraction to achieve both performance and
portability. For binary files,
.B LibXDiff
implements both (with some modification) the algorithm described in
.IR "File System Support for Delta Compression" " by " "Joshua P. MacDonald" ,
and the method described in
.IR "Fingerprinting by Random Polynomials" " by " "Michael O. Rabin" "."
While for text files it follows directives described in
.IR "An O(ND) Difference Algorithm and Its Variations" " by " "Eugene W. Myers" .
Memory files used by the library are basically a collection of buffers
that store the file content. There are two different requirements for memory
files when passed to diff/patch functions. Text files for diff/patch functions
require that a single line do not have to spawn across two different memory
file blocks. Binary diff/patch functions require memory files to be compact.
A compact memory files is a file whose content is stored inside a single block.
Functionalities inside the library are available to satisfy these rules.
Using the
.B XDL_MMF_ATOMIC
memory file flag it is possible to make writes to not split the written
record across different blocks, while the functions
.BR xdl_mmfile_iscompact ()
,
.BR xdl_mmfile_compact ()
and
.BR xdl_mmfile_writeallocate ()
are usefull to test if the file is compact and to create a compacted version
of the file itself. The text file differential output uses the raw unified output
format, by omitting the file header since the result is always relative to
a single compare operation (between two files). The output format of the binary
patch file is proprietary (and binary) and it is basically a collection of
copy and insert commands, like described inside the MacDonald paper.
.SS Functions
The following functions are defined:
.TP
.BI "int xdl_set_allocator(memallocator_t const *" malt ");"
The
.B LibXDiff
library enable the user to set its own memory allocator, that will be used
for all the following memory requests. The allocator must be set before
to start calling the
.B LibXDiff
library with a call to
.BR xdl_set_allocator ().
The memory allocator structure contains the following members:
.nf
typedef struct s_memallocator {
void *priv;
void *(*malloc)(void *priv, unsigned int size);
void (*free)(void *priv, void *ptr);
void *(*realloc)(void *priv, void *ptr, unsigned int nsize);
} memallocator_t;
.fi
The
.BR malloc ()
function pointer will be used by
.B LibXDiff
to request a memory block of
.I size
bytes. The
.BR free ()
function pointer will be called to free a previously allocated block
.I ptr
, while the
.BR realloc ()
will be used to resize the
.I ptr
to a new
.I nsize
size in bytes. The
.B priv
structure member will be passed to the
.BR malloc (), free (), realloc ()
functions as first parameter. The
.B LibXDiff
user must call
.BR xdl_set_allocator ()
before starting using the library, otherwise
.B LibXDiff
functions will fail due to the lack of memory allocation support.
A typical initialization sequence for
.B POSIX
systems will use the standard
.BR malloc (3),
.BR free (3),
.BR realloc (3)
and will look like:
.nf
void *wrap_malloc(void *priv, unsigned int size) {
return malloc(size);
}
void wrap_free(void *priv, void *ptr) {
free(ptr);
}
void *wrap_realloc(void *priv, void *ptr, unsigned int size) {
return realloc(ptr, size);
}
void my_init_xdiff(void) {
memallocator_t malt;
malt.priv = NULL;
malt.malloc = wrap_malloc;
malt.free = wrap_free;
malt.realloc = wrap_realloc;
xdl_set_allocator(&malt);
}
.fi
.TP
.BI "void *xdl_malloc(unsigned int " size ");"
Allocates a memory block of
.I size
bytes using the
.B LibXDiff
memory allocator. The user can specify its own allocator using the
.BR xdl_set_allocator ()
function. The
.BR xdl_malloc ()
return a pointer to the newly allocated block, or
.B NULL
in case of failure.
.TP
.BI "void xdl_free(void *" ptr ");"
Free a previously allocated memory block pointed by
.IR ptr .
The
.I ptr
block must has been allocated using either
.BR xdl_malloc ()
or
.BR xdl_realloc ().
.TP
.BI "void *xdl_realloc(void *" ptr ", unsigned int " nsize ");"
Resizes the memory block pointed by
.I ptr
to a new size
.IR nsize .
Return the resized block if successful, or
.B NULL
in case the reallocation fails. After a successful reallocation, the old
.I ptr
block is to be considered no more valid.
.TP
.BI "int xdl_init_mmfile(mmfile_t *" mmf ", long " bsize ", unsigned long " flags ");"
Initialize the memory file
.I mmf
by requiring an internal block size of
.IR bsize .
The
.I flags
parameter is a combination of the following flags :
.br
.IP
.B XDL_MMF_ATOMIC
Writes on the memory file will be atomic. That is, the data will not be split
on two or more different blocks.
Once an
.BR xdl_init_mmfile ()
succeeded, a matching
.BR xdl_free_mmfile ()
must be called when the user has done using the memory file, otherwise serious
memory leaks will happen.
The function return 0 if succeed or -1 if an error is encountered.
.TP
.BI "void xdl_free_mmfile(mmfile_t *" mmf ");"
Free all the data associated with the
.I mmf
memory file.
.TP
.BI "int xdl_mmfile_iscompact(mmfile_t *" mmf ");"
Returns an integer different from 0 if the
.I mmf
memory file is compact, 0 otherwise. A compact memory file is one that have
the whole content stored inside a single block.
.TP
.BI "int xdl_seek_mmfile(mmfile_t *" mmf ", long " off ");"
Set the current data pointer of the memory file
.I mmf
to the specified offset
.I off
from the beginning of the file itself. Returns 0 if successful or -1 if an error
happened.
.TP
.BI "long xdl_read_mmfile(mmfile_t *" mmf ", void *" data ", long " size ");"
Request to read
.I size
bytes from the memory file
.I mmf
by storing the data inside the
.I data
buffer. Returns the number of bytes read into the
.I data
buffer. The amount of data read can be lower than the specified
.IR size .
The function returns -1 if an error happened.
.TP
.BI "long xdl_write_mmfile(mmfile_t *" mmf ", void const *" data ", long " size ");"
Request to write
.I size
bytes from the specified buffer
.I data
into the memory file
.IR mmf .
If the memory file has been created using the
.B XDL_MMF_ATOMIC
flag, the write request will not be split across different blocks.
Note that all write operations done on memory files do append data at the end
the file, and writes in the middle of it are allowed. This is because the library
memory file abstraction does not need this functionality to be available.
The function returns the number of bytes written or a number lower than
.I size
if an error happened.
.TP
.BI "long xdl_writem_mmfile(mmfile_t *" mmf ", mmbuffer_t *" mb ", int " nbuf ");"
Request to sequentially write
.I nbuf
memory buffers passed inside the array
.I mb
into the memory file
.IR mmf .
The memory buffer structure is defined as :
.nf
typedef struct s_mmbuffer {
char *ptr;
long size;
} mmbuffer_t;
.fi
The
.I ptr
field is a pointer to the user data, whose size is specified inside the
.I size
structure field. The function returns the total number of bytes written
or a lower number if an error happened.
.TP
.BI "void *xdl_mmfile_writeallocate(mmfile_t *" mmf ", long " size ");"
The function request to allocate a write buffer of
.I size
bytes in the
.I mmf
memory file and returns the pointer to the allocated buffer. The user will
have the responsibility to store
.I size
bytes (no more, no less) inside the memory region pointed to by the returned pointer.
The files size will grow of
.I size
bytes as a consequence of this operation. The function will return
.B NULL
if an error happened.
.TP
.BI "long xdl_mmfile_ptradd(mmfile_t *" mmf ", char *" ptr ", long " size ", unsigned long " flags ");"
The function adds a user specified block to the end of the memory file
.IR mmf .
The block first byte is pointed to by
.I ptr
and its length is
.I size
bytes. The
.I flags
parameter can be used to specify attributes of the user memory block. Currently
supported attributes are:
.br
.IP
.B XDL_MMB_READONLY
Specify that the added memory block must be treated as read-only, and
every attempt to write on it should result in a failure of the memory file
writing functions.
The purpose of this function is basically to avoid copying memory around,
by helping the library to not drain the CPU cache. The function returns
.I size
in case of success, or -1 in case of error.
.TP
.BI "void *xdl_mmfile_first(mmfile_t *" mmf ", long *" size ");"
The function is used to return the first block of the
.I mmf
memory file block chain. The
.I size
parameter will receive the size of the block, while the function will return
the pointer the the first byte of the block itself. The function returns
.B NULL
if the file is empty.
.TP
.BI "void *xdl_mmfile_next(mmfile_t *" mmf ", long *" size ");"
The function is used to return the next block of the
.I mmf
memory file block chain. The
.I size
parameter will receive the size of the block, while the function will return
the pointer the the first byte of the block itself. The function returns
.B NULL
if the current block is the last one of the chain.
.TP
.BI "long xdl_mmfile_size(mmfile_t *" mmf ");"
The function returns the size of the specified memory file
.IR mmf .
.TP
.BI "int xdl_mmfile_cmp(mmfile_t *" mmf1 ", mmfile_t *" mmf2 ");"
Request to compare two memory files
.IR mmf1 " and " mmf2
and returns 0 if files are identical, or a value different from 0 if
files are different.
.TP
.BI "int xdl_mmfile_compact(mmfile_t *" mmfo ", mmfile_t *" mmfc ", long " bsize ", unsigned long " flags ");"
Request to create a compact version of the memory file
.I mmfo
into the (uninitialized) memory file
.IR mmfc .
The
.I bsize
parameter specify the requested block size and
.I flags
specify flags to be used to create the new
.I mmfc
memory file (see
.BR xdl_init_mmfile ()
). The function returns 0 if succedded or -1 if an error happened.
.TP
.BI "int xdl_diff(mmfile_t *" mmf1 ", mmfile_t *" mmf2 ", xpparam_t const *" xpp ", xdemitconf_t const *" xecfg ", xdemitcb_t *" ecb ");"
Request to create the difference between the two text memory files
.IR mmf1 " and " mmf2 .
The
.I mmf1
memory files is considered the "old" file while
.I mmf2
is considered the "new" file. So the function will create a patch file
that once applied to
.I mmf1
will give
.I mmf2
as result. Files
.IR mmf1 " and " mmf2
must be atomic from a line point of view (or, as an extreme, compact), that
means that a single test line cannot spread among different memory file blocks.
The
.I xpp
parameter is a pointer to a structure :
.nf
typedef struct s_xpparam {
unsigned long flags;
} xpparam_t;
.fi
that is used to specify parameters to be used by the file differential algorithm.
The
.I flags
field is a combination of the following flags :
.IP
.B XDF_NEED_MINIMAL
Requires the minimal edit script to be found by the algorithm (may be slow).
The
.I xecfg
parameter point to a structure :
.nf
typedef struct s_xdemitconf {
long ctxlen;
} xdemitconf_t;
.fi
that is used to configure the algorithm responsible of the creation the the
differential file from an edit script. The
.I ctxlen
field is used to specify the amount of context to be emitted inside the
differential file (the value 3 is suggested for normal operations).
The parameter
.I ecb
is a pointer to a structure :
.nf
typedef struct s_xdemitcb {
void *priv;
int (*outf)(void *, mmbuffer_t *, int);
} xdemitcb_t;
.fi
that is used by the differential file creation algorithm to emit the created
data. The
.I priv
field is an opaque pointer to a user specified data, while the
.I outf
field point to a callback function that is called internally to emit algorithm
generated data rappresenting the differential file. The first parameter of the
callback is the same
.I priv
field specified inside the
.B xdemitcb_t
structure. The second parameter point to an array of
.B mmbuffer_t
(see above for a definition of the structure) whose element count is specified
inside the last parameter of the callback itself. The callback will always be
called with entire records (lines) and never a record (line) will be emitted
using two different callback calls. This is important because if the called will
use another memory file to store the result, by creating the target memory file with
.B XDL_MMF_ATOMIC
will guarantee the "atomicity" of the memory file itself.
The function returns 0 if succeeded or -1 if an error occurred.
.TP
.BI "int xdl_patch(mmfile_t *" mmf ", mmfile_t *" mmfp ", int " mode ", xdemitcb_t *" ecb ", xdemitcb_t *" rjecb ");"
Request to patch the memory file
.I mmf
using the patch file stored in
.IR mmfp .
The
.I mmf
memory file
.B is not
changed during the operation and can be considered as read only.
The
.I mode
parameter can be one of the following values :
.IP
.B XDL_PATCH_NORMAL
Perform standard patching like if the patch memory file
.I mmfp
has been created using
.I mmf
as "old" file.
.IP
.B XDL_PATCH_REVERSE
Apply the reverse patch. That means that the
.I mmf
memory file has to be considered as if it was specified as "new" file during
the differential operation (
.BR xdl_diff ()
). The result of the operation will then be the file content that was used
as "old" file during the differential operation.
The following flags can be specified (by or-ing them) to one of the above:
.IP
.B XDL_PATCH_IGNOREBSPACE
Ignore the whitespace at the beginning and the end of the line.
The
.I ecb
will be used by the patch algorithm to create the result file while the
.I rjecb
will be used to emit all differential chunks that cannot be applied.
Like explained above, callbacks are always called with entire records to guarantee
atomicity of the resulting output.
The function returns 0 if succeeded without performing any fuzzy hunk detection,
a positive value if it secceeded with fuzzy hunk detection or -1 if an error occurred
during the patch operation.
.TP
.BI "int xdl_merge3(mmfile_t *" mmfo ", mmfile_t *" mmf1 ", mmfile_t *" mmf2 ", xdemitcb_t *" ecb ", xdemitcb_t *" rjecb ");"
Merges three files together. The
.I mmfo
file is the original one, while
.IR mmf1 " and " mmf2
are two modified versions of
.IR mmfo .
The function works by creating a differential between
.IR mmfo " and " mmf2
and by applying the resulting patch to
.IR mmf1 .
Because of this sequence,
.I mmf1
changes will be privileged against the ones of
.IR mmf2 .
The
.I ecb
will be used by the patch algorithm to create the result file while the
.I rjecb
will be used to emit all differential chunks that cannot be applied.
Like explained above, callbacks are always called with entire records to guarantee
atomicity of the resulting output.
The function returns 0 if succeeded or -1 if an error occurred during the patch operation.
.TP
.BI "int xdl_bdiff(mmfile_t *" mmf1 ", mmfile_t *" mmf2 ", bdiffparam_t const *" bdp ", xdemitcb_t *" ecb ");"
Request to create the difference between the two text memory files
.IR mmf1 " and " mmf2 .
The
.I mmf1
memory files is considered the "old" file while
.I mmf2
is considered the "new" file. So the function will create a patch file
that once applied to
.I mmf1
will give
.I mmf2
as result. Files
.IR mmf1 " and " mmf2
must be compact to make it easy and faster to perform the difference operation.
Functions are available to check for compactness (
.BR xdl_mmfile_iscompact ()
) and to make compact a non-compact file (
.BR xdl_mmfile_compact ()
). An example of how to create a compact memory file (described inside the test
subdirectory) is :
.nf
int xdlt_load_mmfile(char const *fname, mmfile_t *mf, int binmode) {
char cc;
int fd;
long size, bsize;
char *blk;
if (xdl_init_mmfile(mf, XDLT_STD_BLKSIZE, XDL_MMF_ATOMIC) < 0)
return -1;
if ((fd = open(fname, O_RDONLY)) == -1) {
perror(fname);
xdl_free_mmfile(mf);
return -1;
}
if ((size = bsize = lseek(fd, 0, SEEK_END)) > 0 && !binmode) {
if (lseek(fd, -1, SEEK_END) != (off_t) -1 &&
read(fd, &cc, 1) && cc != '\\n')
bsize++;
}
lseek(fd, 0, SEEK_SET);
if (!(blk = (char *) xdl_mmfile_writeallocate(mf, bsize))) {
xdl_free_mmfile(mf);
close(fd);
return -1;
}
if (read(fd, blk, (size_t) size) != (size_t) size) {
perror(fname);
xdl_free_mmfile(mf);
close(fd);
return -1;
}
close(fd);
if (bsize > size)
blk[size] = '\\n';
return 0;
}
.fi
The
.I bdp
parameter points to a structure :
.nf
typedef struct s_bdiffparam {
long bsize;
} bdiffparam_t;
.fi
that is used to pass information to the binary file differential algorithm.
The
.I bsize
parameter specify the size of the block that will be used to decompose
.I mmf1
during the block classification phase of the algorithm (see MacDonald paper).
Suggested values go from 16 to 64, with a preferred power of two characteristic.
The
.I ecb
parameter is used to pass the emission callback to the algorithm responsible
of the output file creation.
The function returns 0 if succeede or -1 if an error is occurred.
.TP
.BI "int xdl_bdiff_mb(mmbuffer_t *" mmb1 ", mmbuffer_t *" mmb2 ", bdiffparam_t const *" bdp ", xdemitcb_t *" ecb ");"
Same as
.BR xdl_bdiff ()
but it works on memory buffer directly. The
.BR xdl_bdiff ()
is implemented internally with a
.BR xdl_bdiff_mb ()
after having setup the two memory buffers from the passed memory files (that must be compact,
as described above). The memory buffer structure is defined as :
.nf
typedef struct s_mmbuffer {
char *ptr;
long size;
} mmbuffer_t;
.fi
An empty memory buffer is specified by setting the
.I ptr
member as
.B NULL
and the
.I size
member as zero. The reason of having this function is to avoid the memory file
preparation, that might involve copying memory from other sources. Using
the
.BR xdl_bdiff_mb (),
the caller can setup the two memory buffer by using, for example,
.BR mmap (2),
and hence avoiding unnecessary memory copies. The other parameters and the return value
of the function
.BR xdl_bdiff_mb ()
are the same as the ones already described in
.BR xdl_bdiff ().
.TP
.BI "int xdl_rabdiff(mmfile_t *" mmf1 ", mmfile_t *" mmf2 ", xdemitcb_t *" ecb ");"
Request to create the difference between the two text memory files
.IR mmf1 " and " mmf2
using the Rabin's polynomial fingerprinting algorithm. This algorithm typically
performs faster and produces smaller deltas, when compared to the XDelta-like one.
The
.I mmf1
memory files is considered the "old" file while
.I mmf2
is considered the "new" file. So the function will create a patch file
that once applied to
.I mmf1
will give
.I mmf2
as result. Files
.IR mmf1 " and " mmf2
must be compact to make it easy and faster to perform the difference operation.

of the output file creation.
The function returns 0 if succeede or -1 if an error is occurred.

.BR xdl_rabdiff_mb ()
are the same as the ones already described in
.BR xdl_rabdiff ().
.TP
.BI "long xdl_bdiff_tgsize(mmfile_t *" mmfp ");"
Given a binary memory file patch, it returns the size that the result file
will have once the patch is applied to the target file. It can be used to
pre-allocate (or write-allocate) a memory block to store the patch result
so that a compact file will be available at the end of the operation. The
function returns the requested size, or -1 if an error occurred during the operation.
.TP
.BI "int xdl_bpatch(mmfile_t *" mmf ", mmfile_t *" mmfp ", xdemitcb_t *" ecb ");"
Request to patch the binary memory file
.I mmf
using the binary patch file stored in
.IR mmfp .
The
.I mmf
memory file
.B is not
changed during the operation and can be considered as read only. The binary
patch algorithm has no notion of context, so the patch operation cannot be
partial (either success or failure). The
.I ecb
parameter contain the callabck (see above for description) used by the binary
patch algorithm to emit the result file. The function returns 0 if succeeded
or -1 if an error occurred during the patch operation.

DESCRIPTION
The LibXDiff library implements basic and yet complete functionalities
to create file differences/patches to both binary and text files. The
library uses memory files as file abstraction to achieve both perfor-
mance and portability. For binary files, LibXDiff implements both (with
some modification) the algorithm described in File System Support for
Delta Compression by Joshua P. MacDonald, and the method described in
Fingerprinting by Random Polynomials by Michael O. Rabin. While for
text files it follows directives described in An O(ND) Difference Algo-
rithm and Its Variations by Eugene W. Myers. Memory files used by the
library are basically a collection of buffers that store the file con-
tent. There are two different requirements for memory files when passed
to diff/patch functions. Text files for diff/patch functions require
that a single line do not have to spawn across two different memory
file blocks. Binary diff/patch functions require memory files to be
compact. A compact memory files is a file whose content is stored
inside a single block. Functionalities inside the library are avail-
able to satisfy these rules. Using the XDL_MMF_ATOMIC memory file flag
it is possible to make writes to not split the written record across
different blocks, while the functions xdl_mmfile_iscompact() ,
xdl_mmfile_compact() and xdl_mmfile_writeallocate() are usefull to test
if the file is compact and to create a compacted version of the file
itself. The text file differential output uses the raw unified output
format, by omitting the file header since the result is always relative
to a single compare operation (between two files). The output format of
the binary patch file is proprietary (and binary) and it is basically a
collection of copy and insert commands, like described inside the Mac-
Donald paper.
Functions
The following functions are defined:
int xdl_set_allocator(memallocator_t const *malt);
The LibXDiff library enable the user to set its own memory allo-
cator, that will be used for all the following memory requests.
The allocator must be set before to start calling the LibXDiff
library with a call to xdl_set_allocator(). The memory alloca-
tor structure contains the following members:
typedef struct s_memallocator {
void *priv;
void *(*malloc)(void *priv, unsigned int size);
void (*free)(void *priv, void *ptr);
void *(*realloc)(void *priv, void *ptr, unsigned int nsize);
} memallocator_t;
The malloc() function pointer will be used by LibXDiff to
request a memory block of size bytes. The free() function
pointer will be called to free a previously allocated block ptr
, while the realloc() will be used to resize the ptr to a new
nsize size in bytes. The priv structure member will be passed to
the malloc(),free(),realloc() functions as first parameter. The
LibXDiff user must call xdl_set_allocator() before starting
using the library, otherwise LibXDiff functions will fail due to
the lack of memory allocation support. A typical initialization
sequence for POSIX systems will use the standard malloc(3),
free(3), realloc(3) and will look like:
void *wrap_malloc(void *priv, unsigned int size) {
return malloc(size);
}
void wrap_free(void *priv, void *ptr) {
free(ptr);
}
void *wrap_realloc(void *priv, void *ptr, unsigned int size) {
return realloc(ptr, size);
}
void my_init_xdiff(void) {
memallocator_t malt;
malt.priv = NULL;
malt.malloc = wrap_malloc;
malt.free = wrap_free;
malt.realloc = wrap_realloc;
xdl_set_allocator(&malt);
}
void *xdl_malloc(unsigned int size);
Allocates a memory block of size bytes using the LibXDiff memory
allocator. The user can specify its own allocator using the
xdl_set_allocator() function. The xdl_malloc() return a pointer
to the newly allocated block, or NULL in case of failure.
void xdl_free(void *ptr);
Free a previously allocated memory block pointed by ptr. The
ptr block must has been allocated using either xdl_malloc() or
xdl_realloc().
void *xdl_realloc(void *ptr, unsigned int nsize);
Resizes the memory block pointed by ptr to a new size nsize.
Return the resized block if successful, or NULL in case the
reallocation fails. After a successful reallocation, the old ptr
block is to be considered no more valid.
int xdl_init_mmfile(mmfile_t *mmf, long bsize, unsigned long flags);
Initialize the memory file mmf by requiring an internal block
size of bsize. The flags parameter is a combination of the fol-
lowing flags :
XDL_MMF_ATOMIC Writes on the memory file will be atomic. That
is, the data will not be split on two or more different blocks.
Once an xdl_init_mmfile() succeeded, a matching
xdl_free_mmfile() must be called when the user has done using
the memory file, otherwise serious memory leaks will happen.
The function return 0 if succeed or -1 if an error is encoun-
tered.
void xdl_free_mmfile(mmfile_t *mmf);
Free all the data associated with the mmf memory file.
int xdl_mmfile_iscompact(mmfile_t *mmf);
Returns an integer different from 0 if the mmf memory file is
compact, 0 otherwise. A compact memory file is one that have the
whole content stored inside a single block.
int xdl_seek_mmfile(mmfile_t *mmf, long off);
Set the current data pointer of the memory file mmf to the spec-
ified offset off from the beginning of the file itself. Returns
0 if successful or -1 if an error happened.
long xdl_read_mmfile(mmfile_t *mmf, void *data, long size);
Request to read size bytes from the memory file mmf by storing
the data inside the data buffer. Returns the number of bytes
read into the data buffer. The amount of data read can be lower
than the specified size. The function returns -1 if an error
happened.
long xdl_write_mmfile(mmfile_t *mmf, void const *data, long size);
Request to write size bytes from the specified buffer data into
the memory file mmf. If the memory file has been created using
the XDL_MMF_ATOMIC flag, the write request will not be split
across different blocks. Note that all write operations done on
memory files do append data at the end the file, and writes in
the middle of it are allowed. This is because the library memory
file abstraction does not need this functionality to be avail-
able. The function returns the number of bytes written or a
number lower than size if an error happened.
long xdl_writem_mmfile(mmfile_t *mmf, mmbuffer_t *mb, int nbuf);
Request to sequentially write nbuf memory buffers passed inside
the array mb into the memory file mmf. The memory buffer struc-
ture is defined as :
typedef struct s_mmbuffer {
char *ptr;
long size;
} mmbuffer_t;
The ptr field is a pointer to the user data, whose size is spec-
ified inside the size structure field. The function returns the
total number of bytes written or a lower number if an error hap-
pened.
void *xdl_mmfile_writeallocate(mmfile_t *mmf, long size);
The function request to allocate a write buffer of size bytes in
the mmf memory file and returns the pointer to the allocated
buffer. The user will have the responsibility to store size
bytes (no more, no less) inside the memory region pointed to by
the returned pointer. The files size will grow of size bytes as
a consequence of this operation. The function will return NULL
if an error happened.
long xdl_mmfile_ptradd(mmfile_t *mmf, char *ptr, long size, unsigned
long flags);
The function adds a user specified block to the end of the mem-
ory file mmf. The block first byte is pointed to by ptr and its
length is size bytes. The flags parameter can be used to specify
attributes of the user memory block. Currently supported
attributes are:
XDL_MMB_READONLY Specify that the added memory block must be
treated as read-only, and every attempt to write on it should
result in a failure of the memory file writing functions.
The purpose of this function is basically to avoid copying mem-
ory around, by helping the library to not drain the CPU cache.
The function returns size in case of success, or -1 in case of
error.
void *xdl_mmfile_first(mmfile_t *mmf, long *size);
The function is used to return the first block of the mmf memory
file block chain. The size parameter will receive the size of
the block, while the function will return the pointer the the
first byte of the block itself. The function returns NULL if the
file is empty.
void *xdl_mmfile_next(mmfile_t *mmf, long *size);
The function is used to return the next block of the mmf memory
file block chain. The size parameter will receive the size of
the block, while the function will return the pointer the the
first byte of the block itself. The function returns NULL if the
current block is the last one of the chain.
long xdl_mmfile_size(mmfile_t *mmf);
The function returns the size of the specified memory file mmf.
int xdl_mmfile_cmp(mmfile_t *mmf1, mmfile_t *mmf2);
Request to compare two memory files mmf1 and mmf2 and returns 0
if files are identical, or a value different from 0 if files are
different.
int xdl_mmfile_compact(mmfile_t *mmfo, mmfile_t *mmfc, long bsize,
unsigned long flags);
Request to create a compact version of the memory file mmfo into
the (uninitialized) memory file mmfc. The bsize parameter spec-
ify the requested block size and flags specify flags to be used
to create the new mmfc memory file (see xdl_init_mmfile() ). The
function returns 0 if succedded or -1 if an error happened.
int xdl_diff(mmfile_t *mmf1, mmfile_t *mmf2, xpparam_t const *xpp,
xdemitconf_t const *xecfg, xdemitcb_t *ecb);
Request to create the difference between the two text memory
files mmf1 and mmf2. The mmf1 memory files is considered the
"old" file while mmf2 is considered the "new" file. So the func-
tion will create a patch file that once applied to mmf1 will
give mmf2 as result. Files mmf1 and mmf2 must be atomic from a
line point of view (or, as an extreme, compact), that means that
a single test line cannot spread among different memory file
blocks. The xpp parameter is a pointer to a structure :
typedef struct s_xpparam {
unsigned long flags;
} xpparam_t;
that is used to specify parameters to be used by the file dif-
ferential algorithm. The flags field is a combination of the
following flags :
XDF_NEED_MINIMAL Requires the minimal edit script to be found by
the algorithm (may be slow).
The xecfg parameter point to a structure :
typedef struct s_xdemitconf {
long ctxlen;
} xdemitconf_t;
that is used to configure the algorithm responsible of the
creation the the differential file from an edit script. The
ctxlen field is used to specify the amount of context to be
emitted inside the differential file (the value 3 is suggested
for normal operations). The parameter ecb is a pointer to a
structure :
typedef struct s_xdemitcb {
void *priv;
int (*outf)(void *, mmbuffer_t *, int);
} xdemitcb_t;
that is used by the differential file creation algorithm to emit
the created data. The priv field is an opaque pointer to a user
specified data, while the outf field point to a callback func-
tion that is called internally to emit algorithm generated data
rappresenting the differential file. The first parameter of the
callback is the same priv field specified inside the xdemitcb_t
structure. The second parameter point to an array of mmbuffer_t
(see above for a definition of the structure) whose element
count is specified inside the last parameter of the callback
itself. The callback will always be called with entire records
(lines) and never a record (line) will be emitted using two dif-
ferent callback calls. This is important because if the called
will use another memory file to store the result, by creating
the target memory file with XDL_MMF_ATOMIC will guarantee the
"atomicity" of the memory file itself. The function returns 0
if succeeded or -1 if an error occurred.
int xdl_patch(mmfile_t *mmf, mmfile_t *mmfp, int mode, xdemitcb_t *ecb,
xdemitcb_t *rjecb);
Request to patch the memory file mmf using the patch file stored
in mmfp. The mmf memory file is not changed during the opera-
tion and can be considered as read only. The mode parameter can
be one of the following values :
XDL_PATCH_NORMAL Perform standard patching like if the patch
memory file mmfp has been created using mmf as "old" file.
XDL_PATCH_REVERSE Apply the reverse patch. That means that the
mmf memory file has to be considered as if it was specified as
"new" file during the differential operation ( xdl_diff() ). The
result of the operation will then be the file content that was
used as "old" file during the differential operation.
The following flags can be specified (by or-ing them) to one of
the above:
XDL_PATCH_IGNOREBSPACE Ignore the whitespace at the beginning
and the end of the line.
The ecb will be used by the patch algorithm to create the result
file while the rjecb will be used to emit all differential
chunks that cannot be applied. Like explained above, callbacks
are always called with entire records to guarantee atomicity of
the resulting output. The function returns 0 if succeeded with-
out performing any fuzzy hunk detection, a positive value if it
secceeded with fuzzy hunk detection or -1 if an error occurred
during the patch operation.
int xdl_merge3(mmfile_t *mmfo, mmfile_t *mmf1, mmfile_t *mmf2,
xdemitcb_t *ecb, xdemitcb_t *rjecb);
Merges three files together. The mmfo file is the original one,
while mmf1 and mmf2 are two modified versions of mmfo. The
function works by creating a differential between mmfo and mmf2
and by applying the resulting patch to mmf1. Because of this
sequence, mmf1 changes will be privileged against the ones of
mmf2. The ecb will be used by the patch algorithm to create the
result file while the rjecb will be used to emit all differen-
tial chunks that cannot be applied. Like explained above, call-
backs are always called with entire records to guarantee atomic-
ity of the resulting output. The function returns 0 if suc-
ceeded or -1 if an error occurred during the patch operation.
int xdl_bdiff(mmfile_t *mmf1, mmfile_t *mmf2, bdiffparam_t const *bdp,
xdemitcb_t *ecb);
Request to create the difference between the two text memory
files mmf1 and mmf2. The mmf1 memory files is considered the
"old" file while mmf2 is considered the "new" file. So the func-
tion will create a patch file that once applied to mmf1 will
give mmf2 as result. Files mmf1 and mmf2 must be compact to make
it easy and faster to perform the difference operation. Func-
tions are available to check for compactness ( xdl_mmfile_iscom-
pact() ) and to make compact a non-compact file (
xdl_mmfile_compact() ). An example of how to create a compact
memory file (described inside the test subdirectory) is :
int xdlt_load_mmfile(char const *fname, mmfile_t *mf, int binmode) {
char cc;
int fd;
long size, bsize;
char *blk;
if (xdl_init_mmfile(mf, XDLT_STD_BLKSIZE, XDL_MMF_ATOMIC) < 0)
return -1;

}
The bdp parameter points to a structure :
typedef struct s_bdiffparam {
long bsize;
} bdiffparam_t;
that is used to pass information to the binary file differential
algorithm. The bsize parameter specify the size of the block
that will be used to decompose mmf1 during the block classifica-
tion phase of the algorithm (see MacDonald paper). Suggested
values go from 16 to 64, with a preferred power of two charac-
teristic. The ecb parameter is used to pass the emission call-
back to the algorithm responsible of the output file creation.
The function returns 0 if succeede or -1 if an error is
occurred.
int xdl_bdiff_mb(mmbuffer_t *mmb1, mmbuffer_t *mmb2, bdiffparam_t const
*bdp, xdemitcb_t *ecb);
Same as xdl_bdiff() but it works on memory buffer directly. The
xdl_bdiff() is implemented internally with a xdl_bdiff_mb()
after having setup the two memory buffers from the passed memory
files (that must be compact, as described above). The memory
buffer structure is defined as :
typedef struct s_mmbuffer {
char *ptr;
long size;
} mmbuffer_t;
An empty memory buffer is specified by setting the ptr member as
NULL and the size member as zero. The reason of having this
function is to avoid the memory file preparation, that might
involve copying memory from other sources. Using the
xdl_bdiff_mb(), the caller can setup the two memory buffer by
using, for example, mmap(2), and hence avoiding unnecessary mem-
ory copies. The other parameters and the return value of the
function xdl_bdiff_mb() are the same as the ones already
described in xdl_bdiff().
int xdl_rabdiff(mmfile_t *mmf1, mmfile_t *mmf2, xdemitcb_t *ecb);
Request to create the difference between the two text memory
files mmf1 and mmf2 using the Rabin's polynomial fingerprinting
algorithm. This algorithm typically performs faster and produces
smaller deltas, when compared to the XDelta-like one. The mmf1
memory files is considered the "old" file while mmf2 is consid-
ered the "new" file. So the function will create a patch file
that once applied to mmf1 will give mmf2 as result. Files mmf1
and mmf2 must be compact to make it easy and faster to perform
the difference operation. Functions are available to check for
compactness ( xdl_mmfile_iscompact() ) and to make compact a
non-compact file ( xdl_mmfile_compact() ). The ecb parameter is
used to pass the emission callback to the algorithm responsible
of the output file creation. The function returns 0 if succeede
or -1 if an error is occurred.
int xdl_rabdiff_mb(mmbuffer_t *mmb1, mmbuffer_t *mmb2, xdemitcb_t
*ecb);
Same as xdl_rabdiff() but it works on memory buffer directly.
The memory buffer structure is defined as :
typedef struct s_mmbuffer {
char *ptr;
long size;
} mmbuffer_t;
An empty memory buffer is specified by setting the ptr member as
NULL and the size member as zero. The reason of having this
function is to avoid the memory file preparation, that might
involve copying memory from other sources. Using the xdl_rabd-
iff_mb(), the caller can setup the two memory buffer by using,
for example, mmap(2), and hence avoiding unnecessary memory
copies. The other parameters and the return value of the func-
tion xdl_rabdiff_mb() are the same as the ones already described
in xdl_rabdiff().
long xdl_bdiff_tgsize(mmfile_t *mmfp);
Given a binary memory file patch, it returns the size that the
result file will have once the patch is applied to the target
file. It can be used to pre-allocate (or write-allocate) a mem-
ory block to store the patch result so that a compact file will
be available at the end of the operation. The function returns
the requested size, or -1 if an error occurred during the opera-
tion.
int xdl_bpatch(mmfile_t *mmf, mmfile_t *mmfp, xdemitcb_t *ecb);
Request to patch the binary memory file mmf using the binary
patch file stored in mmfp. The mmf memory file is not changed
during the operation and can be considered as read only. The
binary patch algorithm has no notion of context, so the patch
operation cannot be partial (either success or failure). The ecb
parameter contain the callabck (see above for description) used
by the binary patch algorithm to emit the result file. The func-
tion returns 0 if succeeded or -1 if an error occurred during
the patch operation.
