If the function belongs to a specific function module, the name must also be prefixed with the module name. For example, if a function is for file systems, its name is prefixed with grub_fs_. If a function is for FAT file system but not for all file systems, its name is prefixed with grub_fs_fat_. The hierarchy is noted this way. + +After a prefix, a function name must start with a verb (such as get or is). It must not be a noun. Some kind of abbreviation is permitted, as long as it wouldn't make code less readable (e.g. init). + +If a function is local, its name may not start with any prefix. It must start with a verb. + +@node Variables +@section Variables + +The rule is mostly the same as functions, as noted above. If a variable is global, its name must be prefixed with grub_ and must consist of only small letters. If the variable belongs to a specific function module, the name must also be prefixed with the module name. For example, if a function is for dynamic loading, its name is prefixed with grub_dl_. If a variable is for ELF but not for all dynamic loading systems, its name is prefixed with grub_dl_elf_. + +After a prefix, a variable name must start with a noun or an adjective (such as name or long) and it should end with a noun. Some kind of abbreviation is permitted, as long as it wouldn't make code less readable (e.g. i18n). + +If a variable is global in the scope of a single file (i.e. it is declared with static), its name may not start with any prefix. It must start with a noun or an adjective. + +If a variable is local, you may choose any shorter name, as long as it wouldn't make code less readable (e.g. i). + +@node Types +@section Types + +The name of a type must be prefixed with grub_ and must consist of only small letters. If the type belongs to a specific function module, the name must also be prefixed with the module name. For example, if a type is for OS loaders, its name is prefixed with grub_loader_. If a type is for Multiboot but not for all OS loaders, its name is prefixed with grub_loader_linux_. + +The name must be suffixed with _t, to emphasize the fact that it is a type but not a variable or a function. + +@node Macros +@section Macros + +If a macro is global, its name must be prefixed with GRUB_ and must consist of only large letters. Other rules are the same as functions or variables, depending on whether a macro is used like a function or a variable. + +@node Comments +@section Comments + +All comments shall be C-style comments, of the form @samp{/* @dots{} */}. + +Comments shall be placed only on a line by themselves. They shall not be placed together with code, variable declarations, or other non-comment entities.

The top-level build rules are in @file{configure.ac}, +@file{grub-core/Makefile.core.def}, and @file{Makefile.util.def}. Each +block in a @file{*.def} file represents a build target, and specifies the +source files used to build it on various platforms. The @file{*.def} files +are processed into AutoGen input by @file{gentpl.py} (which you only need to +look at if you are extending the build system). If you are adding a new +module which follows an existing pattern, such as a new command or a new +filesystem implementation, it is usually easiest to grep +@file{grub-core/Makefile.core.def} and @file{Makefile.util.def} for an +existing example of that pattern to find out where it should be added. + +In general, code that may be run at boot time is in a subdirectory of +@file{grub-core}, while code that is only run from within a full operating +system is in a subdirectory of the top level. + +Low-level boot code, such as the MBR implementation on PC BIOS systems, is +in the @file{grub-core/boot/} directory. + +The GRUB kernel is in @file{grub-core/kern/}. This contains core facilities +such as the device, disk, and file frameworks, environment variable +handling, list processing, and so on. The kernel should contain enough to +get up to a rescue prompt. Header files for kernel facilities, among +others, are in @file{include/}. + +Terminal implementations are in @file{grub-core/term/}. + +Disk access code is spread across @file{grub-core/disk/} (for accessing the +disk devices themselves), @file{grub-core/partmap/} (for interpreting +partition table data), and @file{grub-core/fs/} (for accessing filesystems). +Note that, with the odd specialised exception, GRUB only contains code to +@emph{read} from filesystems and tries to avoid containing any code to +@emph{write} to filesystems; this lets us confidently assure users that GRUB +cannot be responsible for filesystem corruption. + +PCI and USB bus handling is in @file{grub-core/bus/}. + +Video handling code is in @file{grub-core/video/}. The graphical menu +system uses this heavily, but is in a separate directory, +@file{grub-core/gfxmenu/}. + +Most commands are implemented by files in @file{grub-core/commands/}, with +the following exceptions: + +@itemize +@item +A few core commands live in @file{grub-core/kern/corecmd.c}. + +@item +Commands related to normal mode live under @file{grub-core/normal/}. + +@item +Commands that load and boot kernels live under @file{grub-core/loader/}. + +@item +The @samp{loopback} command is really a disk device, and so lives in +@file{grub-core/disk/loopback.c}. + +@item +The @samp{gettext} command lives under @file{grub-core/gettext/}. + +@item +The @samp{loadfont} and @samp{lsfonts} commands live under +@file{grub-core/font/}. + +@item +The @samp{serial}, @samp{terminfo}, and @samp{background_image} commands +live under @file{grub-core/term/}. + +@item +The @samp{efiemu_*} commands live under @file{grub-core/efiemu/}. +@end itemize + +There are a few other special-purpose exceptions; grep for them if they +matter to you. + +Utility programs meant to be run from a full operating system are in +@file{util/}. + +@node Contributing Changes +@chapter Contributing changes +@c By YoshinoriOkuji, VesaJääskeläinen, ColinWatson + +Contributing changes to GRUB 2 is welcomed activity. However we have a +bit of control what kind of changes will be accepted to GRUB 2. +Therefore it is important to discuss your changes on grub-devel mailing list +(see MailingLists). On this page there are some basic details on the +development process and activities. + +First of all you should come up with the idea yourself what you want to +contribute. If you do not have that beforehand you are advised to study this +manual and try GRUB 2 out to see what you think is missing from there. + +Here are additional pointers: +@itemize +@item @url{https://savannah.gnu.org/task/?group=grub GRUB's Task Tracker} +@item @url{https://savannah.gnu.org/bugs/?group=grub GRUB's Bug Tracker} +@end itemize + +If you intended to make changes to GRUB Legacy (<=0.97) those are not accepted +anymore. + +@menu +* Getting started:: +* Typical Developer Experience:: +* When you are approved for write access to project's files:: +@end menu + +@node Getting started +@section Getting started + +@itemize +@item Always use latest GRUB 2 source code. So get that first. + +For developers it is recommended always to use the newest development version of GRUB 2. If development takes a long period of time, please remember to keep in sync with newest developments regularly so it is much easier to integrate your change in the future. GRUB 2 is being developed in a Bazaar (bzr) repository. + +Please check Savannah's GRUB project page for details how to get newest bzr: +@uref{http://savannah.gnu.org/bzr/?group=grub, GRUB 2 bzr Repository} + +@item Compile it and try it out. + +It is always good idea to first see that things work somehow and after that +to start to implement new features or develop fixes to bugs. + +@item Study the code. + +There are sometimes odd ways to do things in GRUB 2 code base. +This is mainly related to limited environment where GRUB 2 is being executed. +You usually do not need to understand it all so it is better to only try to +look at places that relates to your work. Please do not hesitate to ask for +help if there is something that you do not understand. + +@item Develop a new feature. + +Now that you know what to do and how it should work in GRUB 2 code base, please +be free to develop it. If you have not so far announced your idea on grub-devel +mailing list, please do it now. This is to make sure you are not wasting your +time working on the solution that will not be integrated to GRUB 2 code base. + +You might want to study our coding style before starting development so you +do not need to change much of the code when your patch is being reviewed. +(see @ref{Coding style}) + +For every accepted patch there has to exist a ChangeLog entry. Our ChangeLog +consist of changes within source code and are not describing about what the +change logically does. Please see examples from previous entries. + +Also remember that GRUB 2 is licensed under GPLv3 license and that usually +means that you are not allowed to copy pieces of code from other projects. +Even if the source project's license would be compatible with GPLv3, please +discuss it beforehand on grub-devel mailing list. + +@item Test your change. + +Test that your change works properly. Try it out a couple of times, preferably on different systems, and try to find problems with it. + +@item Publish your change. + +When you are happy with your change, first make sure it is compilable with +latest development version of GRUB 2. After that please send a patch to +grub-devel for review. Please describe in your email why you made the change, +what it changes and so on. Please be prepared to receive even discouraging +comments about your patch. There is usually at least something that needs +to be improved in every patch. + +Please use unified diff to make your patch (good match of arguments for diff is @samp{-pruN}). + +@item Respond to received feedback. + +If you are asked to modify your patch, please do that and resubmit it for +review. If your change is large you are required to submit a copyright +agreement to FSF. Please keep in mind that if you are asked to submit +for copyright agreement, process can take some time and is mandatory +in order to get your changes integrated. + +If you are not on grub-devel to respond to questions, most likely your patch +will not be accepted. Also if problems arise from your changes later on, +it would be preferable that you also fix the problem. So stay around +for a while. + +@item Your patch is accepted. + +Good job! Your patch will now be integrated into GRUB 2 mainline, and if it didn't break anything it will be publicly available in the next release. + +Now you are welcome to do further improvements :) +@end itemize + +@node Typical Developer Experience +@section Typical Developer Experience + +The typical experience for a developer in this project is the following: + +@enumerate +@item You find yourself wanting to do something (e.g. fixing a bug). +@item You show some result in the mailing list or the IRC. +@item You are getting to be known to other developers. +@item You accumulate significant amount of contribution, so copyright assignment is processed. +@item You are free to check in your changes on your own, legally speaking. +@end enumerate + +At this point, it is rather annoying that you ought to ask somebody else every +change to be checked in. For efficiency, it is far better, if you can commit +it yourself. Therefore, our policy is to give you the write permission to our +official repository, once you have shown your skill and will, +and the FSF clerks have dealt with your copyright assignment. + +@node When you are approved for write access to project's files +@section When you are approved for write access to project's files + +As you might know, GRUB is hosted on +@url{https://savannah.gnu.org/projects/grub Savannah}, thus the membership +is managed by Savannah. This means that, if you want to be a member of this +project: + +@enumerate +@item You need to create your own account on Savannah. +@item You can submit ``Request for Inclusion'' from ``My Groups'' on Savannah. +@end enumerate + +Then, one of the admins can approve your request, and you will be a member. +If you don't want to use the Savannah interface to submit a request, you can +simply notify the admins by email or something else, alternatively. But you +still need to create an account beforehand. + +NOTE: we sometimes receive a ``Request for Inclusion'' from an unknown person. +In this case, the request would be just discarded, since it is too dangerous +to allow a stranger to be a member, which automatically gives him a commit +right to the repository, both for a legal reason and for a technical reason. + +If your intention is to just get started, please do not submit a inclusion +request. Instead, please subscribe to the mailing list, and communicate first +(e.g. sending a patch, asking a question, commenting on another message...). + +@node Error Handling +@chapter Error Handling + +Error handling in GRUB 2 is based on exception handling model. As C language +doesn't directly support exceptions, exception handling behavior is emulated +in software. + +When exception is raised, function must return to calling function. If calling +function does not provide handling of the exception it must return back to its +calling function and so on, until exception is handled. If exception is not +handled before prompt is displayed, error message will be shown to user. + +Exception information is stored on @code{grub_errno} global variable. If +@code{grub_errno} variable contains value @code{GRUB_ERR_NONE}, there is no active +exception and application can continue normal processing. When @code{grub_errno} has +other value, it is required that application code either handles this error or +returns instantly to caller. If function is with return type @code{grub_err_t} is +about to return @code{GRUB_ERR_NONE}, it should not set @code{grub_errno} to that +value. Only set @code{grub_errno} in cases where there is error situation. + +Simple exception forwarder. +@example +grub_err_t +forwarding_example (void) +@{ + /* Call function that might cause exception. */ + foobar (); + + /* No special exception handler, just forward possible exceptions. */ + if (grub_errno != GRUB_ERR_NONE) + @{ + return grub_errno; + @} + + /* All is OK, do more processing. */ + + /* Return OK signal, to caller. */ + return GRUB_ERR_NONE; +@} +@end example + +Error reporting has two components, the actual error code (of type +@code{grub_err_t}) and textual message that will be displayed to user. List of +valid error codes is listed in header file @file{include/grub/err.h}. Textual +error message can contain any textual data. At time of writing, error message +can contain up to 256 characters (including terminating NUL). To ease error +reporting there is a helper function @code{grub_error} that allows easier +formatting of error messages and should be used instead of writing directly to +global variables. + +Example of error reporting. +@example +grub_err_t +failing_example () +@{ + return grub_error (GRUB_ERR_FILE_NOT_FOUND, + "Failed to read %s, tried %d times.", + "test.txt", + 10); +@} +@end example + +If there is a special reason that error code does not need to be taken account, +@code{grub_errno} can be zeroed back to @code{GRUB_ERR_NONE}. In cases like this all +previous error codes should have been handled correctly. This makes sure that +there are no unhandled exceptions. + +Example of zeroing @code{grub_errno}. +@example +grub_err_t +probe_example () +@{ + /* Try to probe device type 1. */ + probe_for_device (); + if (grub_errno == GRUB_ERR_NONE) + @{ + /* Device type 1 was found on system. */ + register_device (); + return GRUB_ERR_NONE; + @} + /* Zero out error code. */ + grub_errno = GRUB_ERR_NONE; + + /* No device type 1 found, try to probe device type 2. */ + probe_for_device2 (); + if (grub_errno == GRUB_ERR_NONE) + @{ + /* Device type 2 was found on system. */ + register_device2 (); + return GRUB_ERR_NONE; + @} + /* Zero out error code. */ + grub_errno = GRUB_ERR_NONE; + + /* Return custom error message. */ + return grub_error (GRUB_ERR_UNKNOWN_DEVICE, "No device type 1 or 2 found."); +@} +@end example + +Some times there is a need to continue processing even if there is a error +state in application. In situations like this, there is a needed to save old +error state and then call other functions that might fail. To aid in this, +there is a error stack implemented. Error state can be pushed to error stack +by calling function @code{grub_error_push ()}. When processing has been completed, +@code{grub_error_pop ()} can be used to pop error state from stack. Error stack +contains predefined amount of error stack items. Error stack is protected for +overflow and marks these situations so overflow error does not get unseen. +If there is no space available to store error message, it is simply discarded +and overflow will be marked as happened. When overflow happens, it most likely +will corrupt error stack consistency as for pushed error there is no matching +pop, but overflow message will be shown to inform user about the situation. +Overflow message will be shown at time when prompt is about to be drawn. + +Example usage of error stack. +@example +/* Save possible old error message. */ +grub_error_push (); + +/* Do your stuff here. */ +call_possibly_failing_function (); + +if (grub_errno != GRUB_ERR_NONE) + @{ + /* Inform rest of the code that there is error (grub_errno + is set).
