"""Complicated notification for CVS checkins.
This script is used to provide email notifications of changes to the CVS
repository. These email changes will include context diffs of the changes.
Really big diffs will be trimmed.
This script is run from a CVS loginfo file (see $CVSROOT/CVSROOT/loginfo). To
set this up, create a loginfo entry that looks something like this:
mymodule /path/to/this/script %%s some-email-addr@your.domain
In this example, whenever a checkin that matches `mymodule' is made, this
script is invoked, which will generate the diff containing email, and send it
to some-email-addr@your.domain.
Note: This module used to also do repository synchronizations via
rsync-over-ssh, but since the repository has been moved to SourceForge,
this is no longer necessary. The syncing functionality has been ripped
out in the 3.0, which simplifies it considerably. Access the 2.x versions
to refer to this functionality. Because of this, the script is misnamed.
It no longer makes sense to run this script from the command line. Doing so
will only print out this usage information.
Usage:
%(PROGRAM)s [options] <%%S> email-addr [email-addr ...]
Where options is:
--cvsroot=<path>
Use <path> as the environment variable CVSROOT. Otherwise this
variable must exist in the environment.
--help
-h
Print this text.
<%%S>
CVS %%s loginfo expansion. When invoked by CVS, this will be a single
string containing the directory the checkin is being made in, relative
to $CVSROOT, followed by the list of files that are changing. If the
%%s in the loginfo file is %%{sVv}, context diffs for each of the
modified files are included in any email messages that are generated.
email-addrs
At least one email address.

Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
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.>

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

You should have received a copy of the GNU Lesser General Public

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:

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".)

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

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.>

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:

only one write is present. If two writes are in an then and an
else branch of an if, the local can still be final.

types correctly: byte[] is something completely different than
int[].

attribute even when not all attributes should be read. They are
needed by TransformConstructors, see above.

line breaks in not completed expressions since implicit parentheses
would destroy the syntax. No need to put line break option on stack.

uninitialized objects in local or stack slots on backwards jump or
exception blocks. Sun's jdk also doesn't check it, and I never
understood why it is necessary. But see JVM Spec 4.9.4.

and import keywords.
* jode/flow/TransformExceptionHandlers.java:
(getPredecessor): New function.
(getMonitorExitSlot): New function.
(skipFinExitChain): New function.
(removeJSR): Replaced by ...
(removeBadJSR): ... this.
(checkAndRemoveJSR): Use the new functions. Much simpler and
handles nested synchronized blocks. It now traces the whole JSR
and monitorexit chain before a jump to the first entry via
skipFinExitChain, then checks and remove the first JSR
resp. monitorexit. JSR jumps are simply ignored now.
(checkAndRemoveMonitorExit): likewise.
* jode/flow/StructuredBlock.java (prependBlock): New function.
* jode/flow/CatchBlock.java (makeDeclaration): Generate name
of dummyLocal, since nobody else will generate it.
* jode/bytecode/BasicBlockReader.java (readCode): Remove bogus
exceptionHandlers, whose catchers just throw the exception again.
This kind of entries are inserted by an obfuscator and would break
JODE.
* jode/util/UnifyHash.java (iterateHashCode): Call cleanUp,
to clean unneeded references.
* jode/flow/TransformConstructors.java (transformOneField):
Changed to private. Take field number as parameter. Check that
expression doesn't contain a FieldOperator for a later field of
the same class or a PutFieldOperator. Changed all callers.

types can't be merged, return tObject as common super type.
* jode/type/ArrayType.java (getGeneralizedType): If array elem
type can't be intersected, return tObject as common super type.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patch from Jode 1.1 tree:
* jode/expr/Expression.java (updateParentTypes): Call setType,
instead of merging the types. Other childs want to know about the
type change as well.
* jode/decompiler/LocalInfo.java (combineWith): Reorganized a bit,
but no changes.
* jode/expr/InvokeOperator.java (dumpExpression): Always print
the ThisOperator if a field is from a parent class of an outer
class is used. And always qualify the this operator if not
innermost.
2001-07-14 Jochen Hoenicke <jochen@gnu.org>
Applied patches from the Jode 1.1 tree:
* jode/decompiler/TabbedPrintWriter.java: Better gnu style handling:
(openBraceClass) (closeBraceClass)
(openBraceNoIndent) (closeBraceNoIndent): new functions.
(closeBraceNoSpace): Removed.
* jode/decompiler/TabbedPrintWriter.java (GNU_SPACING): new constant.
(printOptionalSpace): Print space for GNU_SPACING.
* jode/decompiler/Options.java (setOptions): changed gnu style
to include GNU_SPACING.

open/closeBraceClass.
* jode/decompiler/MethodAnalyzer.java (dumpSource): Use
open/closeBraceNoIndent. Call printOptionalSpace.
* jode/decompiler/InvokeOperator.java (dumpExpression):
Call printOptionalSpace, use open/closeBraceClass for inner
classes.
* jode/decompiler/UnaryOperator.java (dumpExpression): Call
printOptionalSpace.
Added pascal style from Rolf Howarth <rolf@squarebox.co.uk>
* jode/decompiler/Decompiler.java (setOption): detect pascal option.
* jode/decompiler/TabbedPrintWriter.java (BRACE_FLUSH_LEFT):
new constant.
(openBrace, openBraceContinue, closeBrace, closeBraceNoSpace,
closeBraceContinue): handle flush left.
* jode/type/NullType.java (intersection): Removed, since the
version in ReferenceType is more correct. Before
tNull.isOfType(tRange(X,tNull)) returned false, which lead to
incorrect behaviour in InvokeOperator.needsCast.
* jode/decompiler/FieldAnalyzer.java (dumpSource): Removed the
"= null" hack for final fields; it was not correct, since the
field could be initialized in a constructor.
* jode/decompiler/TabbedPrintWriter.java (BreakPoint.endOp):
Simplified the code, copy options always from child.
* jode/expr/InvokeOperator.java (isGetClass): Allow the method to
be declared inside an outer class: We simply check if we can get
the method analyzer.
(simplify): handle unifyParam.
* jode/expr/PopOperator.java (getBreakPenalty): return penalty of
inner expression. (dumpExpression): Call dumpExpression of
subexpression immediately without priority.

features like inner and anonymous classes. </p>
<p><a href=".">Click here</a> to browse the files online.

<p>I have some simple step by step pages. There are three
possibilities:
<ul>
<li> <a href="jode-useapplet.html"> Using the applet version</a>.

<h2>Known bugs</h2>
<p>There may be situations, where the code doesn't understand complex

code should still be compileable. This does especially happen when
you compile with `-O' flag and javac has inlined some methods. </p>
<p>Sometimes this program may exit with an <code>Exception</code> or
produce incorrect code. Most time the code can't be compiled, so that
it can be easily spotted. If you have one of these problems (except
those that occur on some of the <code>jode.test</code> files, I would
be very interested in a bug report (including the <code>class</code>
file, if possible).</p>
<p>Sometimes it generates some <code>GOTO</code> expression and
labels. This can't be compiled, but shouldn't happen any more with
javac or jikes.</p>
<p>It doesn't handle inner and anonymous classes, yet. You can
decompile them separately, though (use `<code>+$</code>' switch under
jikes), but there is a bug in javac, so that a final variable is twice
initialized. If you encounter this problem just remove the doubled
line by hand. </p>
<p><b>New!</b> The latest <a href="snapshot">snapshot</a> can handle

<h2>Why did I wrote it?</h2>
<p>Someday I found <code>guavad</code>, a disassembler for java byte
code (it does similar things like <code>javap&nbsp;-c</code>). I used
it on a class file, and found that it was possible to reconstruct the
original java code. First I did it by hand on some small routines,
but I soon realized that it was a rather stupid task, and that I could
write a <a href="../perl/dasm_to_java.perl"><code>perl</code> script</a>
that does the same. At the end of the next day I had a working
decompiler.</p>
<p>Now while it was working, it was not easy to use. You had to
decompile the code first with a disassembler, cut the method, you
wanted to decompile and then run the perl script on it. So I decided
to get some information of the class files and do this all
automatically. I decided to write it in <code>java</code> now,
because it suited best.</p>
<p>Just for the records: the java code is now more than 50 times
bigger than the original perl script and is still growing.</p>

</body> JODE is a java package containing a decompiler and an optimizer for
</html> java. This package is freely available under the GNU General Public
License.
The decompiler reads in class files and produces something similar to
the original java file. Of course this can't be perfect: There is no
way to produce the comments or the names of local variables (except
when the java files were compiled with `-g') and there are often more
ways to write the same thing. However, jode does its job quite well.
The optimizer transforms class files in various ways with
can be controlled by a script file.
Please note that most software licenses forbid to decompile class
files. Use this decompiler only, if you have legal rights to
decompile the class (e.g. on your own code).
The features of the decompilers are:
* Systematic flow analysis, that can decompile every java code
without the need of goto (which doesn't exists in java).
* Type deduction, that can guess the type of local variables, even if
it is an interface type that doesn't occur in the bytecode.
* Handling of inner and anonymous classes.
* Different indentation styles available.
* It can decompile itself (194 classes) without a single error.
* It can decrypt strings on the fly, that were encrypted by an obfuscator.
Known bugs of the decompiler:
- Some jdk1.3 synthetic access functions aren't understood. The
produced source contains access$xxx functions, but it still compiles.
- There may be other bugs, that cause Exceptions or invalid code.
If you have such a problems don't hesitate to issue a bug report.
Please include the <code>class</code> file if possible.
Limitations:
- If not all dependent classes can be found, the verifier (which is
run before decompilation starts) may exit with a type error. You
can decompile it with --verify=off, but take the warning serious,
that the types may be incorrect. There's sometimes no way to guess
the right type, if you don't have access the full class hierarchie.
But if you don't have the dependent classes, you can't compile the
code again, anyway, so why do you want to decompile it?
- There may be situations, where jode doesn't understand complex
expressions. In this case many ugly temporary variables are used,
but the code should still be compileable. This does especially
happen when you compile with `-O' flag and javac has inlined some
methods.
The features of the obfuscator are:
* Modular design, you can plug the obfuscation transformation you need
together via the script file.
* Strong analysis, that optimizes away fields, expressions that are
known to be constant (and reverts the flow obfuscation of Zelix
Klassmaster)
* Can also be used as Optimizer, without any obfuscation at all, it
will preserve the local variable table and line number table.
* Many different renaming options, you can also simply add your own.
PRELIMINARIES:
See INSTALL for installation instructions.
USAGE:
First set the classpath. It should contain the jar file jode-1.1.jar,
the gnu getopt package and the sun collection package for 1.1. For
the swingui program you also need swing in you classpath.
You can then decompile a class file with:
java jode.decompiler.Main --classpath program.jar,libfoo.jar org.package.Class
or a complete package with
java jode.decompiler.Main --classpath libfoo.jar program.jar
For a graphical user interface based on swing try:
java jode.swingui.Main --classpath jarfile1.jar
The obfuscator/deobfuscator can be run with a script:
java jode.obfuscator.Main obfuscation.jos
See the web documents for more information about the script syntax.

- warn about Class.forName and list occurences. Warn about all other occurences of Class.forName()
- work around Class.forName, by creating a new version using a hash
table that maps md5 sums of old names to obfuscated names.
This should be put into the constant analyzer. The simple
analyzer should only do the warnings.
- Transforming the class hierarchy, e.g. combining two totally
unrelated classes together into one class or make some class
to implement some interfaces, that it previously didn't.
- Doing flow obfuscation, i.e. do some tests, that one knows to
succeed always, and jump to funny position if the test fails.

deobfuscator cannot remove them again.
DeObfuscator: DeObfuscator:
- generate nice names: - Deobfuscator should detect inner/anonymous classes and mark them
- classes: derive name from super. as such. It should be possible with the renaming table to mark
- fields: derive name from type. inner classes as well. Inner classes are easy to detect; there
- give synthetic methods the right attribute and name (e.g. class$) constructor has a special form. And the information is very
- detect inner classes and give suitable names. useful for the decompiler.
This should be done with some generalize interface similar to (or
instead of) Transformer
- Deobfuscator should generate nicer names. This should be a
special Renamer. The renamer should analyze short methods and
call them getXXX, isXXX, setXXX if apropriate, detect synthetic
methods and similar. Class names should be derived from super
class or interface (e.g. Enumeration), fields should be derived
from their type, maybe also from their assignments.
One can build more renamer, each handles some special cases and
calls the next one, if it can't handle an identifier.

<section title="Wish List">
<p>This section contains features that I think would be great to have,
but are also very hard to implement. </p>
<p>Currently this are all my own ideas. But if you send me an idea
for an interesting feature, I will add it to this list.</p>
<h2><i>Out</i>line inlined methods</h2>
<p>If java gets called with `<code>-O</code>' switch, it inlines methods,
that are private, final, or static and contain no loops. When
decompiling this it sometimes produces really ugly code. The right
way to solve this would be to <i>out</i>line the code again. This is
possible but requires to find the inlined method. </p>
<p>The name `outline' was suggested by <a
href="http://www.informatik.uni-oldenburg.de/~mw">Michael</a>.
</p>
<h2>Better names of local variables</h2>
<p>The local variable naming is very stupid. Even with pretty it just
names the variable after the type with a unifying number appended. A
method containing very much objects of the same type looks very
ugly. </p>
<p>My plan is looking at the assignments. If we have locals in
assignments</p>
<pre>
int l_1 = array.length
String l_2 = object.getName()
</pre>
<p>we could name them "length" and "name". If we
have assignments:</p>
<pre>
MenuItem local_1 = new MenuItem("Open");
MenuItem local_2 = new MenuItem("Save");
</pre>
<p>good names would be <code>miOpen</code> and <code>miSave</code>. </p>
<p>It is currently possible to assign a <i>(hint name,type)</i> pair
to a local. If the type matches, the local will be named after
<i>hint name</i>. This could be extended by giving them several
weighted hints and constructing the name in an intelligent way. </p>
<h2>Better deobfuscation features</h2>
<p>First there should be a good Renamer: Methods that simply
return a field value should be renamed to get<i>FieldName</i>.
Fields should be named after their type, maybe also by assignments
(see section about local variable names).</p>
<p>The deobfuscator should detect inner and anonymous variables,
synthetic methods and so on, and rename them accordingly.</p>
<h2>Handling of Class.forName in obfuscator</h2>
<p>The obfuscator should detect Class.forName constructs (and
similarly for methods and fields) and if their parameters are constant
it should change the parameter according to the rename function. </p>
<h2>Merging javadoc comments</h2>
<p>It would be nice if the decompiler could merge the javadoc comments
into the class file. More and more people use javadoc to comment the
public api of their java classes. It shouldn't be too difficult to
copy them back into the java code. </p>
<p>This doesn't need to be built into the decompiler. A script that takes
the javadoc pages and the decompiled code can easily merge them.</p>

form. For compiling the source code, you need several other packages,
check the <a href="links.html">links page</a>. You need a unix like
environment for compilation.</p>
<p>The simplest way to get it, especially for non unix users, is in
precompiled form, though. There are two jar archives in the download
area:</P>
<ul> <li>jode-1.1-JDK1.1.jar is for JDK&nbsp;1.1. If you want to use
the swing interface, you have to download swing separately, all other
packages are already included in the archive. </li>
<li>jode-1.1.jar is for JDK&nbsp;1.2 or better. It should run
without any other package.</li> </ul>

<section title="Subversion Repository">
<p>You can get the latest sources from the <a

<section title="FAQ - Frequently Asked Questions">
This is a list of some questions that pop up from time to time.
</section>
<section title="Decompiler issues">
<h3>Does Jode support Java 5?</h3>
<p>It does not support generics/vararg method or the new for loop at
the moment. It produces readable code and I think it may even compile
again. But it is not compatible as the generics and varargs
information is not included.</p>
<h3>Jode crashes with ExceptionHandler order failed</h3>
<p>Try jode-1.1.2pre1 or the latest CVS version. If it still does not
work rewrite <code>jode.flow.TransformExceptionHandlers</code> and
send me the fix :) </p>
<p>Since Java 1.4 the format for finally and synchronized blocks
changed again. It was always a very difficult task to reconstruct
<code>finally</code> blocks correctly and the code is huge and very
hard to maintain. With Java 5 it gets even worse.</p>
<h3>The decompiler crashes with a VerifyException, what can I do?</h3>
<p>The class isn't verifiable, probably because there is not enough
information about used classes. See the question about the
classpath.</p>
<p>This could also be caused by malicious bytecode, or because there
is a bug in Jode's verifier, or because Sun decided to change the
definition of correct bytecode, again.</p>
<h3>What should be included in the classpath?</h3>
<p>Jode needs to know the full class hierarchie to guess the types.
This includes not only the classes in the program, but also the
libraries used by the java program, even the Java runtime library.
You should set the classpath to include all these classes.</p>
<p>If you don't specify the classpath on the command line, Jode uses
the same as your Java Virtual Machine.</p>
<p>As last resort, if Jode can't find a class in the classpath it uses
reflection to ask the Virtual Machine. This works quite well, but
loading classes can have side effects, e.g. when AWT classes are
loaded, an AWT thread is created, even though Jode doesn't need
it.</p>
<h3>Why doesn't Jode decompile my inner class
<code>MyClass$Inner.class</code>?</h3>
<p>You should decompile the outermost class (<code>MyClass</code> in
this case). The produced code contains the inner class. </p>
</section>
<section title="Obfuscator issues">
<h3>What should be included in the classpath?</h3>
<p>The program, all libraries, the Java runtime library. Don't omit a
library even when you don't want to obfuscate it.</p>
<h3>What should I preserve</h3>
<p>The most common mistake is to preserve a class. In most cases this
is not what you want. This only makes sure the class won't be
renamed, it doesn't prevent it from being stripped. Instead you
should preserve methods and constructors. The constructor is just a
method with the special name <tt>&lt;init&gt;</tt>. </p>
<p> Another common mistake is to omit the type
signature, e.g. to preserve <tt>Class.main</tt> instead of
<tt>Class.main.([Ljava/lang/String;)V</tt>. That doesn't work. If
you don't want to care about the format of the type signature use a
wildcard as in <tt>Class.main.*</tt>. </p>
<h3>What is a type signature</h3>
<p>The type signature is a machine readable representation of a java
type that is used all over in java bytecode. The JDK ships a command
named <tt>javap</tt>. With <tt>java -s</tt> you can lists the fields
and methods of a class with their type signatures.</p>
<p> If you are interested in the format of type signatures read the
Java Virtual Machine Specification, Chapter 4.3 Descriptors</p>

<section title="History">
<p>Someday I found <code>guavad</code>, a disassembler for java byte
code (it does similar things like <code>javap&nbsp;-c</code>). I used
it on a class file, and found that it was possible to reconstruct the
original java code. First I did it by hand on some small routines,
but I soon realized that it was a rather stupid task. So I wrote a
small <a href="dasm_to_java.perl"><code>perl</code> script</a> that
did this process automatically. At the end of the next day I had my
first working decompiler.</p>
<p>Now while the <code>perl</code> script is working, it is not easy
to use. You have to decompile the code first with a disassembler, cut
out the code of a single method, and run the perl script on it. I
decided to get the bytecode directly out of the class files and do
this all automatically. I decided to write it in <code>java</code>
now, because it suited best.</p>
<p>Just for the records: the java code is now more than 50 times
bigger than the original perl script and is still growing.</p>

<section title="Introduction">
<P><i>JODE</i> is a java package containing a decompiler and an
optimizer for java. This package is <a href="license.html">freely
available</a> under the GNU GPL. The bytecode package and the core
decompiler is now under GNU Lesser General Public License, so you can
integrate it in your project.</p>
<P>The decompiler reads in <tt>class</tt> files and produces something
similar to the original <tt>java</tt> file. Of course this can't be
perfect: There is no way to produce the comments or the names of local
variables (except when compiled with debuging) and there are often
more ways to write the same thing. However, <i>JODE</i> does its job quite
well, so you should give it a try and <a href="applet.html">start the
applet</a>.</P>
<P>The optimizer transforms <tt>class</tt> files in various ways with
can be controlled by a script file. It supports the following
operations:</p>
<ul>
<li>Renaming class, method, field and local names to shorter,
obfuscated, or unique names or according to a given translation
table</li>
<li>Removing debugging information</li>
<li>Removing dead code (classes, fields, methods) and constant
fields</li>
<li>Optimizing local variable allocation</li>
</ul>
</section>
<section title="News">
<ul>
<li><i>JODE</i> 1.1.1 is out. With support for javac v8 (jdk 1.3). </li>
<li>The license changed to LGPL for the bytecode interface and decompiler.</li>
</ul>
</section>
<section title="Known Bugs">
<p>The current version has problems try/catch/finally code produced
by java 1.4 compiler. You may try the latest CVS version or pre-release
instead.</p>
<p>Some jdk1.3 synthetic access functions aren't understood. The
produced source contains access$xxx functions, but it still compiles.</p>
<p>There may be other bugs, that cause Exceptions or invalid code.
If you have such a problems don't hesitate to issue a bug report.
Please include the <code>class</code> file if possible.</p>
</section>
<section title="Limits">
<p>If not all dependent classes can be found, the verifier (which is
run before decompilation starts) may exit with a type error. You
can decompile it with <tt>--verify=off</tt>, but take the warning
serious, that types may be incorrect. There's sometimes no way to
guess the right type, if you don't have access the full class
hierarchie.<br>
This is not a bug in the verifier: java will complain the same way,
if it is run with bytecode verification turned on. And if you don't
have the dependent classes, you can't compile the code again.</p>
<p>There may be situations, where the code doesn't understand complex
expressions. In this case many ugly temporary variables are used, but
the code should still be compileable. This does especially happen
when you compile with <tt>`-O'</tt> flag and javac has inlined some
methods. </p>

Press the start button to decompile this applet. You may change the
class path and class name to point to a class file of your choice.
But note that most browsers doesn't allow loading files from a
different server.<br><br>
Save probably doesn't work, because it is forbidden by the browser.<br><br>
You may give multiple entries in the class path field separated by a
comma. The components may be local or remote zip or jar files or
directories. Note that browsers forbid accesses to different hosts or
local files that are not in a subdirectory of the applet
directory.<br><br>
BTW: If you just want to read the source, you may <a
href="http://www.informatik.uni-oldenburg.de/~delwi/jode">browse it
online</a> <code>:-)</code><br><br>
You can download this, look <a href="jode-useapplet.html">here</a> for

<h1>Step by Step</h1>
You need java version 1.1 or higher. In the following description I
assume you have the JDK 1.1, residing in <code>/usr/lib/java</code>.
For other installations you have to adopt the paths. Also I use the
bourne shell syntax.
<ol>
<li> Set the classpath. It should include the jode_cls.zip as well as
the directory where the class files you want to decompile resides.
You can also specify a zip file instead of a directory. It is
also a good idea to include the zip resp. jar file containing the
basic <code>java.*</code> class files.
<pre>
export CLASSPATH=$HOME/jode_cls.zip:$HOME/download:/usr/lib/java/lib/classes.zip
</pre>
</li>
<li> Now you can start the graphical interface as following (Note the
case of the parameter)
<pre>
java jode.JodeWindow
</pre>
</li>
<li> The classpath field should already contain the classpath you set
above. The class field contains <code>jode.JodeWindow</code> and
you may push start immediately to decompile this class.
</li>
<li> If you want to decompile your own <code>.class</code> file, enter
the name of the file without <code>.class</code> extension and
push the start button. Change the class path if it doesn't point
to the right directory.
</li>
<li> After decompiling, you can save the file using the save button.
</li>
</ol>
<h1>Packaged classes</h1>
If the class file belongs to a package (like jode.JodeWindow) you
have to give the full qualified class name (the package names
separated by a dot followed by the class name). The class path should
point to the directory containing the package sub directories in this
case. <br><br>
<h1>Command line utility</h1>
There is also a command line utility which is much more powerful, but
also more difficult to use. You can start it (after setting the
classpath) with
<pre>
java jode.Decompiler
</pre>
and get a list of the supported parameters. To decompile the whole
decompiler you can use these magic lines:
<pre>
mkdir src
CLASSPATH=jode_cls.zip java jode.Decompiler --dest src \
`unzip -v jode_cls.zip|grep .class|cut -c59-|sed s/.class//|sed s?/?.?g`
</pre>
<h1>Obfuscator</h1>
So you want to protect your classes from decompiling? Well that is
your choice. You may use my obfuscator. The class files are
decompileable again (except when using -strong option, but this is
reversable by obfuscating again), but at least the information about
the names of identifiers are completely lost. <br><br>
The obfuscator is quite difficult to use (this is why I hided this
section here) and there is only a short description of the command
line parameters:
<pre>
CLASSPATH=jode_cls.zip java jode.Obfuscator
</pre>
As a hint, to obfuscate the obfuscator use the following command line:
<pre>
CLASSPATH=jode_cls.zip java jode.Obfuscator \
-cp jode_cls.zip:/usr/lib/java/lib/classes.zip -d obfuscated.zip \
-weak -revtable translate.tbl -swaporder \
-preserve jode.Obfuscator.main jode
</pre>
The options <code>-unique</code> and <code>-table</code> can be
helpful to deobfuscate obfuscated code.

<h1>Step by Step</h1>
If you want to use the applet version you need a recent Internet
Explorer or Netscape which supports java 1.1. You can also use the
appletviewer of the java development kit.
<ol>
<li> Copy <a

>jode_cls.zip</a> to the <b>same</b> directory.
</li>
<li> Copy the <code>.class</code> file or <code>zip</code> file, you
want to decompile, to that directory.
</li>
<li> Load the html file into Netscape or Internet Explorer.
</li>
<li> Set the classpath simply to `<code>.</code>' (without quotes).
You may also specify a zip or jar file here. Note that applet and
class files must be in the same directory due to security policy. <br>
You can also change the default classpath in the html file.
</li>
<li> Enter the name of the class without <code>.class</code>
extension.
</li>
<li> Press start button in applet. </li>
<li> Press save button to save the decompiled code. </li>

You need java version 1.1 or higher. I suggest using the Sun JDK or

for other virtual machines the paths and the name of the java

set CLASSPATH=c:\temp\jode_cls.zip;c:\temp;c:\jdk1.2\jre\lib\rt.jar
</pre>

An uptodate version of this page is located here.</a><p>
<h2>What is it?</h2>
<P>This is a decompiler for java I have written in my spare time. It
takes class-files as input and produces something similar to the
original java-File. Of course this can't be perfect: There is no way
to produce the comments or the names of local variables (except when
compiled with <code>-g</code>) and there are often more ways to write
the same thing. But it does its job quite well.</P>
<h2>Quick Test</h2>
I have now an applet interface to the decompiler.
<a href="jode-applet.html">Check it out</a>.
<h2>How to get it</h2>
<P>You can donwload the files in zip form.
The <a href="jode_src.zip">sources</a> contain only the
<code>java</code> files, the <a href="jode_cls.zip">classes</a>
contain only the <code>class</code> files. </p>
<p>I also have a <a href="jode.tar.gz">tar.gz file</a> containing only
the <code>RCS</code> directories. This is the form I maintain the
project, but you probably need unix and a few tools to use them.</p>
<p>There are also some <a href="snapshot/">snapshots</a> that have new
features like inner and anonymous classes. </p>
<p><a href=".">Click here</a> to browse the files online.
</p>
<h2>How to use it</h2>
<p>I have some simple step by step pages. There are three
possibilities:
<ul>
<li> <a href="jode-useapplet.html"> Using the applet version</a>.
This can make problem due to java's security policy, but is the
simplest way and works on most platforms.
</li>
<li> If you use Windows, you should look on <a
href="jode-win.html">this page</a>.</li>
<li> Unix users should look on <a href="jode-unix.html">this page</a>.
</ul>
<h2>Known bugs</h2>
<p>There may be situations, where the code doesn't understand complex
expressions. In this many ugly temporary variables are used, but the
code should still be compileable. This does especially happen when
you compile with `-O' flag and javac has inlined some methods. </p>
<p>Sometimes this program may exit with an <code>Exception</code> or
produce incorrect code. Most time the code can't be compiled, so that
it can be easily spotted. If you have one of these problems (except
those that occur on some of the <code>jode.test</code> files, I would
be very interested in a bug report (including the <code>class</code>
file, if possible).</p>
<p>Sometimes it generates some <code>GOTO</code> expression and
labels. This can't be compiled, but shouldn't happen any more with
javac or jikes.</p>
<p>It doesn't handle inner and anonymous classes, yet. You can
decompile them separately, though (use `<code>+$</code>' switch under
jikes), but there is a bug in javac, so that a final variable is twice
initialized. If you encounter this problem just remove the doubled
line by hand. </p>
<p><b>New!</b> The latest <a href="snapshot">snapshot</a> can handle
inner and anonymous classes.</p>
<h2>Why did I wrote it?</h2>
<p>Someday I found <code>guavad</code>, a disassembler for java byte
code (it does similar things like <code>javap&nbsp;-c</code>). I used
it on a class file, and found that it was possible to reconstruct the
original java code. First I did it by hand on some small routines,
but I soon realized that it was a rather stupid task, and that I could
write a <a href="../perl/dasm_to_java.perl"><code>perl</code> script</a>
that does the same. At the end of the next day I had a working
decompiler.</p>
<p>Now while it was working, it was not easy to use. You had to
decompile the code first with a disassembler, cut the method, you
wanted to decompile and then run the perl script on it. So I decided
to get some information of the class files and do this all
automatically. I decided to write it in <code>java</code> now,
because it suited best.</p>
<p>Just for the records: the java code is now more than 50 times
bigger than the original perl script and is still growing.</p>

@section Highlevel analysis
@cindex passes
@section The passes
JODE works in three passes:
@subsection Pass 1: Initialize
In the initialize pass the methods, fields and inner classes are read in
and the inner classes are recursively initialized. In this pass the
complexity of the class is calculated. Anonymous and method scoped
classes aren't even considered yet.
@subsection Pass 2: Analyze
The analyze pass is the real decompilation pass: The code of the methods
is transformed into flow blocks and merged to one flow block as
described in a previous section. The in/out analysis for the local
variables is completed, and the locals are merged as necessary. The
parameter 0 for non static method is marked as ThisOperator in this
pass.
The constructors are analyzed first. If they initialize synthetic
fields, this is taken as clear sign that this are outer value
parameters. So afterwards, these synthetic fields know their value.
Then the methods are analyzed. Each method remembers the anonymous
classes it creates for Pass 3, but these classes are not yet
initialized. Inner classes aren't analyzed yet, either.
@subsection Pass 3: Analyze Inner
As the name of this pass makes clear the inner classes are initialized
in this pass, i.e. first Pass 2 and 3 are invoked for the inner classes.
After that the method scoped classes are analyzed: For each constructor
it is first check if one surrounding method knows about it. If not, a
new class analyzer is created for the method scoped class and Pass 1--3
are invoked. Every surrounding method is then told about this new class
analyzer.
After this pass, every anonymous constructor is analyzed, so we know
which constructor parameters can be outer values. The constructor
transformation may force some other outer values, though. It is also
known, in which method a method scoped class must be declared.
@subsection Pass 4: Make Declarations
The last pass begins with transforming the constructors of a class. Now
the outer values are fixed and the constructor parameters and synthetic
fields are told their values.
After that every method determines where to declare local variables and
method scoped classes. Local variables are declared as final if a
method scoped class uses it as outer value. The name of local
variables is guessed now.
This pass is done recursively for inner and method scoped classes.

<section title="Using the Decompiler">
<p>After you have <a href="download.html">downloaded</a> the jar archive
put it into your <tt>CLASSPATH</tt>. The package
<tt>swingall.jar</tt> is also needed if you are using JDK 1.1.</p>
<ul><li>Under Windows you have to start a MSDOS session and type
something like:
<pre>
set CLASSPATH=C:\download\jode-<use version>.jar;C:\swing\swingall.jar
</pre>
<li>Under Unix you start a shell and type (for bourne shell):
<pre>export CLASSPATH=/tmp/jode-<use version>.jar:/usr/local/swing/swingall.jar</pre>
or for csh:
<pre>setenv CLASSPATH /tmp/jode-<use version>.jar:/usr/local/swing/swingall.jar</pre>
</ul>
<br>
There is also a batch file for windows and a script file for unix,
that you can use. You can extract it with the following command:
<pre>
jar -xvf jode-<use version>".jar bin/jode.bat <i>resp.</i> bin/jode
</pre>
Edit the file to adapt it to your paths and put it to a convenient location.
</section>
<section title="Command Line Interface">
The most powerful way to start <I>JODE</I>'s decompiler is the command
line interface. Some people don't like long command lines; they
should go to the next section. <br>
Start the class <tt>jode.decompiler.Main</tt> with the options. The
following command will give a complete list of the available commands:
<pre>java jode.decompiler.Main --help</pre>
If you want to decompile a jar package you can do it this way:
<pre>java jode.decompiler.Main --dest srcdir program.jar</pre>
If you have installed the batch file/script, you can use it like this:
<pre>jode --dest srcdir program.jar</pre>
<h3><a name="awt">AWT Interface</a></h3>
The AWT Interface looks exactly like the <a href="applet.html">
applet</a>. In fact the applet uses the AWT Interface. You start it
after setting the <tt>CLASSPATH</tt> (see <a
href="#decompiler">above</a>), with
<pre>java jode.decompiler.Window</pre>
In the classpath line you can enter a number of jar files, zip files
and directories separated by comma(<tt>,</tt>). Then enter the
dot(<tt>.</tt>) separated name of the class you want to decompile.
Press the <code>start</code> button and the decompiled class should
appear. You can save it via the <code>save</code> button.
<h3><a name="swing">Swing Interface</a></h3>
For the swing interface you need java version 1.2 or the separately
available swing package (see <a href="links.html#swing">link
page</a>. You can invoke it with the following command (JDK1.2 only):
<pre>
java -jar jode-<use version>.jar classes.jar
</pre>
or if you have set the classpath (see above)
<pre>
java jode.swingui.Main classes.jar
<i>resp.</i> jode swi classes.jar
</pre>
<p>The swing interface will show the package hierarchie of all classes
in the classpath on the left side. You can now select a class and the
decompiled code will appear on the right side. Via the menu, you may
change the classpath or switch between package hierarchie tree and
class inheritence tree.</p>
<p>The swing interface is very useful to browse through class files if
you don't have the source code. You can also use it to trace bugs in
library code. It is not meant to generate <tt>java</tt> files and so
you won't find a save option there.</p>
<h3><a name="java">Java Interface</a></h3>
<p>If you want to integrate <i>JODE</i> into your own java program,
you can use the <a
href="http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jode/jode/jode/decompiler/Decompiler.java?rev=jode_1_1&amp;content-type=text/vnd.viewcvs-markup"
><code>jode.decompiler.Decompiler</code></a>
class. Note that the LGPL allows dynamic linking as long as you don't change
Jode itself. Please tell me if you use <i>JODE</i> in this way.</p>
<p>You should ship <code>jode-1.1-embedded.jar</code> with your program. This jar file is
available in the <sflink href="project/showfiles.php">download area</a>.
It works only under JDK&nbsp;1.2 and above.</p>
</section>
<section title="Using the Obfuscator">
<p>To use the obfuscator you should first create a script file, say <a
href="myproject.jos"><tt>myproject.jos</tt></a>. Then you can invoke the
obfuscator with:</p>
<pre>
java jode.obfuscator.Main myproject.jos
</pre>
<p>The script file should contain the following options: </p>
<p>First select the classpath. You should include everything in the
classpath that you need to run your application. This also includes
the system class files (Sun puts them into <code>classes.zip</code> or
<code>rt.jar</code>))</p>
<pre>
classpath = "c:\\jdk1.2\\jre\\lib\\rt.jar","d:\\project\\java",
"ftp://www.myorg.org/pub/classlib.jar"
</pre>
<p>Specify where you want the obfuscated classes to go. I recommend
to write them directly into a zip file, but you can also give a
directory.</p>
<pre>
dest = "obfuscated.zip"
</pre>
<p>You can make <i>JODE</i> write its translation table. This table
can be used later to undo the name obfuscation, or you can look there
to decrypt exceptions you may get.</p>
<pre>
revtable = "translat.tbl"
</pre>
<p>Select what you want to strip. There are several
possibilities, which can be separated by comma(<tt>,</tt>):</p>
<dl>
<dt>unreach</dt>
<dd>strip unreachable methods and classes.</dd>
<dt>source</dt>
<dd>remove the name of the java file (exceptions will get unreadable).</dd>
<dt>lnt</dt>
<dd>remove the line number table (exceptions will get unreadable).</dd>
<dt>lvt</dt>
<dd>remove the local variable table (debugging doesn't work).</dd>
<dt>inner</dt>
<dd>strip inner class info (reflection doesn't work correctly).</dd>
</dl>
<pre>
strip = "unreach","lvt","inner"
</pre>
<p>Select the packages and classes you want to obfuscate. You should
only include libraries, that you don't ship separately. If you give a
package, all classes and subpackages are loaded. You can also use
<code>*</code> as wild card, that matches everything (including dots).
</p>
<pre>
load = new WildCard { value = "org.myorg.myproject" },
new WildCard { value = "org.myorg.mylib*" },
new WildCard { value = "org.otherorg.shortlib" }
</pre>
<p>Select the methods and classes you want to preserve. This is
the <tt>main</tt> method for applications and the default constructor
<tt>&lt;init&gt;.()V</tt> for applets, resource bundles and other classes
that you load manually at runtime. <br>
You have to give the method
name and the type signature to identify your method. <tt>javap
-s</tt> will show you the type signatures for your classes, but you
may also use <tt>*</tt>, to select all methods with that name.
If you have serializable classes and want to preserve their serialized
form you can use the <tt>SerializePreserver</tt>. </p>
<pre>
preserve = new SerializePreserver,
new WildCard { value = "org.myorg.ApplicationClass.main.*" },
new WildCard { value = "org.myorg.AppletClass.&lt;init&gt;.()V" },
new WildCard { value = "org.resources.Bundle*.&lt;init&gt;.()V" },
</pre>
<p>If you want to obfuscate (or just shorten) the identifier you can
specify a renamer. There are currently following renamer
available</p>
<dl><dt>StrongRenamer</dt>
<dd>Renames to the shortest possible name. You can give a charset
that should be used. It uses the same name as much as possible.</dd>
<dt>UniqueRenamer</dt>
<dd>Renames to unique identifier of the form <tt>xxx123</tt>. Useful
to reduce name conflicts, before you decompile an obfuscated package.</dd>
<dt>NameSwapper</dt>
<dd>This renamer just swaps the names. This is a funny obfuscation
option that is not very strong, but very confusing.</dd>
<dt>KeywordRenamer</dt>
<dd>Renames identifiers to keyword. You can give your own list of
keywords as parameters. Resulting code is not decompilable directly,
<b>but it is <i>not</i> legal bytecode either</b>. Some paranoid
web browsers refuse to run applets containing keywords as identifiers
(and they are completely within the Java VM spec).</dd>
</dl>
<pre>
renamer = new StrongRenamer
</pre>
<p>You can also create a renaming table with the same format as the
table written by revtable. The entries in the table get precedence
over renamer. Entries not in the table will get renamed by the
renamer.</p>
<pre>
table = "translat.tbl"
</pre>
<p>Now you can select the analyzer. The purpose of the
analyzer is to mark all reachable methods, find out which methods
needs to get the same name (overloading), and which method names
mustn't change (overload of library methods, e.g. <tt>nextElement</tt>
for <tt>Enumeration</tt>s). There are currently two analyzers.
</p>
<dl><dt>SimpleAnalyzer</dt>
<dd>Straight forward analyzer. It is fast and will remove dead code
on method basis.</dd>
<dd><dt>ConstantAnalyzer</dt>
<dd>Strong analyzer that will determine, which fields and instructions
have constant values. It will remove dead code on instruction basis
and replace constant instruction with a load of the constant, or
remove them completely.<br> This analyzer is especially useful to
revert the flow obfuscation of some other obfuscators.</dd>
</dl>
<pre>
analyzer = new ConstantAnalyzer
</pre>
<p>Pre- and Post transformers transform the bytecode before
resp. after the Analyzer runs. Using this default should be okay.
You may remove the LocalOptimizer, though, if you have problems.</p>
<p>In the future I may add some new post transformers, that do string
encryption, flow obfuscation and similar things. If you want to write
your own Transformers please contact me, since the next version will
change the bytecode interface.</p>
<pre>
post = new LocalOptimizer, new RemovePopAnalyzer
