+LIBXENLIGHT CODING STYLE
+========================
+
+
+AN APOLOGY AND WARNING
+----------------------
+
+Much of the code in libxl does not yet follow this coding style
+document in every respect. However, new code is expected to conform.
+
+Patches to improve the style of existing code are welcome. Please
+separate these out from functional changes.
+
+If it is not feasible to conform fully to the style while patching old
+code, without doing substantial style reengineering first, we may
+accept patches which contain nonconformant elements, provided that
+they don't make the coding style problem worse overall.
+
+In this case, the new code should conform to the prevailing style in
+the area being touched.
+
+
+MEMORY ALLOCATION
+-----------------
+
+Memory allocation for libxl-internal purposes should normally be done
+with the provided gc mechanisms; there is then no need to free. See
+"libxl memory management" in libxl.h.
+
+
+CONVENTIONAL VARIABLE NAMES
+---------------------------
+
+The following local variable names should be used where applicable:
+
+ int rc; /* a libxl error code - and not anything else */
+ int r; /* the return value from a system call (or libxc call) */
+ bool ok; /* the success return value from a boolean function */
+
+ uint32_t domid;
+ libxl__gc *gc;
+ libxl__egc *egc;
+ libxl__ao *ao;
+
+ libxl_foo_bar_state *fbs; /* local variable */
+ libxl_foo_bar_state foo_bar; /* inside another state struct */
+
+
+CONVENIENCE MACROS
+------------------
+
+There are a number of convenience macros which shorten the program and
+avoid opportunity for mistakes. In some cases non-use of the macros
+produces functional bugs or incorrect error handling. Use the macros
+whenever they are applicable. For example:
+
+ Usually, don't use: Instead, use (see libxl_internal.h):
+ libxl__log[v] LOG, LOGE, LOGEV
+ libxl__sprintf GCSPRINTF
+ libxl__*alloc et al. GCNEW, GCNEW_ARRAY, GCREALLOC_ARRAY
+ isalnum etc. directly CTYPE
+ libxl__ctx_[un]lock CTX_LOCK, CTX_UNLOCK
+ gc=...; ao=...; EGC_GC, AO_GC, STATE_AO_GC
+ explicit gc creation GC_INIT, GC_FREE
+ memset(..,0,sizeof..) FILLZERO
+
+Instead of malloc et al one should (as an exception to the above) use
+libxl__{zalloc,calloc,realloc} etc but passing NOGC.
+
+ERROR HANDLING
+--------------
+
+Unless, there are good reasons to do otherwise, the following error
+handling and cleanup paradigm should be used:
+
+ * All local variables referring to resources which might need
+ cleaning up are declared at the top of the function, and
+ initialised to a sentinel value indicating "nothing allocated".
+ For example,
+ libxl_evgen_disk_eject *evg = NULL;
+ int nullfd = -1;
+
+ * If the function is to return a libxl error value, `rc' is
+ used to contain the error code, but it is NOT initialised:
+ int rc;
+
+ * There is only one error cleanup path out of the function. It
+ starts with a label `out:'. That error cleanup path checks for
+ each allocated resource and frees it iff necessary. It then
+ returns rc. For example,
+ out:
+ if (evg) libxl__evdisable_disk_eject(gc, evg);
+ if (nullfd >= 0) close(nullfd);
+ return rc;
+
+ * Function calls which might fail (ie most function calls) are
+ handled by putting the return/status value into a variable, and
+ then checking it in a separate statement:
+ char *dompath = libxl__xs_get_dompath(gc, bl->domid);
+ if (!dompath) { rc = ERROR_FAIL; goto out; }
+
+ * If a resource is freed in the main body of the function (for
+ example, in a loop), the corresponding variable has to be reset to
+ the sentinel at the point where it's freed.
+
+Whether to use the `out' path for successful returns as well as error
+returns is a matter of taste and convenience for the specific
+function. Not reusing the out path is fine if the duplicated function
+exit code is only `CTX_UNLOCK; GC_FREE;' (or similar).
+
+If you reuse the `out' path for successful returns, there may be
+resources which are to be returned to the caller rather than freed.
+In that case you have to reset the local variable to `nothing here',
+to avoid the resource being freed on the out path. That resetting
+should be done immediately after the resource value is stored at the
+applicable _r function parameter (or equivalent). Do not test `rc' in
+the out section, to discover whether to free things.
+
+The uses of the single-line formatting in the examples above are
+permitted exceptions to the usual libxl code formatting rules.
+
+
+
+IDEMPOTENT DATA STRUCTURE CONSTRUCTION/DESTRUCTION
+--------------------------------------------------
+
+Nontrivial data structures (in structs) should come with an idempotent
+_dispose function, which must free all resources associated with the
+data structure (but not free the struct itself).
+
+Such a struct should also come with an _init function which
+initialises the struct so that _dispose is a no-op.
+
+
+ASYNCHRONOUS/LONG-RUNNING OPERATIONS
+------------------------------------
+
+All long-running operations in libxl need to use the asynchronous
+operation machinery. Consult the programmer documentation in
+libxl_internal.h for details - search for "Machinery for asynchronous
+operations".
+
+The code for asynchronous operations should be laid out in
+chronological order. That is, where there is a chain of callback
+functions, each subsequent function should be, textually, the next
+function in the file. This will normally involve predeclaring the
+callback functions. Synchronous helper functions should be separated
+out into a section preceding the main callback chain.
+
+Control flow arrangements in asynchronous operations should be made as
+simple as possible, because it can otherwise be very hard to see
+through the tangle.
+
+
+When inventing a new sub-operation in asynchronous code, consider
+whether to structure it formally as a sub-operation with its own state
+structure. (See, for example, libxl__datacopier_*.)
+
+An ao-suboperation state structure should contain, in this order:
+ * fields that the caller must fill in, and which are,
+ effectively, the parameters to the operation, including:
+ - libxl__ao *ao
+ - the callback function pointer(s), which
+ should be named callback or callback_*.
+ * shared information fields or ones used for returning information
+ to the calling operation
+ * private fields
+These sections should be clearly demarcated by comments.
+
+An asynchronous operation should normally have an idempotent stop or
+cancel function. It should normally also have an _init function for
+its state struct, which arranges that the stop is a no-op.
+
+The permitted order of calls into your ao operation's methods must be
+documented in comments, if it is nontrivial.
+
+
+When using an ao sub-operation, you should normally:
+ * Physically include the sub-operation state struct in your
+ own state struct;
+ * Use CONTAINER_OF to find your own state struct at the start of
+ your implementations of the sub-operation callback functions;
+ * Unconditionally initialise the sub-operation's struct (with its
+ _init method) in your own _init method.
+ * Unconditionally cancel or destroy the sub-operation in your own
+ cancel or destroy method.
+
+
+FORMATTING AND NAMING
+---------------------
+
+Blatantly copied from qemu and linux with few modifications.
+
+
+1. Whitespace
+
+Of course, the most important aspect in any coding style is whitespace.
+Crusty old coders who have trouble spotting the glasses on their noses
+can tell the difference between a tab and eight spaces from a distance
+of approximately fifteen parsecs. Many a flamewar have been fought and
+lost on this issue.
+
+Libxenlight indents are four spaces. Tabs are never used, except in
+Makefiles where they have been irreversibly coded into the syntax.
+Spaces of course are superior to tabs because:
+
+ - You have just one way to specify whitespace, not two. Ambiguity breeds
+ mistakes.
+ - The confusion surrounding 'use tabs to indent, spaces to justify' is gone.
+ - Tab indents push your code to the right, making your screen seriously
+ unbalanced.
+ - Tabs will be rendered incorrectly on editors who are misconfigured not
+ to use tab stops of eight positions.
+ - Tabs are rendered badly in patches, causing off-by-one errors in almost
+ every line.
+ - It is the libxenlight coding style.
+
+Do not leave whitespace dangling off the ends of lines.
+
+
+2. Line width
+
+Lines are limited to 75 characters.
+
+Rationale:
+ - Some people like to tile their 24" screens with a 6x4 matrix of 80x24
+ xterms and use vi in all of them. The best way to punish them is to
+ let them keep doing it.
+ - In an 80 column terminal, some room needs to be left for > quoting
+ characters, +/- diff characters, and so on, in emails.
+ - Code and especially patches is much more readable if limited to a sane
+ line length. Eighty is traditional.
+ - It is the libxenlight coding style.
+
+
+3. Naming
+
+C is a Spartan language, and so should your naming be. Unlike Modula-2
+and Pascal programmers, C programmers do not use cute names like
+ThisVariableIsATemporaryCounter. A C programmer would call that
+variable "tmp", which is much easier to write, and not the least more
+difficult to understand.
+
+HOWEVER, while mixed-case names are frowned upon, descriptive names for
+global variables are a must. To call a global function "foo" is a
+shooting offense.
+
+GLOBAL variables (to be used only if you _really_ need them) need to
+have descriptive names, as do global functions. If you have a function
+that counts the number of active users, you should call that
+"count_active_users()" or similar, you should _not_ call it "cntusr()".
+
+Encoding the type of a function into the name (so-called Hungarian
+notation) is brain damaged - the compiler knows the types anyway and can
+check those, and it only confuses the programmer.
+
+LOCAL variable names should be short, and to the point. If you have
+some random integer loop counter, it should probably be called "i".
+Calling it "loop_counter" is non-productive, if there is no chance of it
+being mis-understood. Similarly, "tmp" can be just about any type of
+variable that is used to hold a temporary value.
+
+Local variables used to store return values should have descriptive name
+like "rc" or "ret". Following the same reasoning the label used as exit
+path should be called "out".
+
+Function arguments which are used to return values to the caller
+should be suffixed `_r' or `_out'.
+
+Variables, type names and function names are
+lower_case_with_underscores.
+Type names and function names use the prefix libxl__ when internal to
+libxenlight and libxl_ when exported in libxl.h.
+Xl should avoid using libxl_ and libxl__ as prefix for its own function
+names.
+
+When wrapping standard library functions, use the prefix libxl_ to alert
+readers that they are seeing a wrapped version; otherwise avoid this prefix.
+
+Typedefs are used to eliminate the redundant 'struct' keyword.
+It is the libxenlight coding style.
+
+
+4. Statements
+
+Don't put multiple statements on a single line.
+Don't put multiple assignments on a single line either.
+Error code paths with an if statement and a goto or a return on the same
+line are allowed. Examples:
+
+ if (rc) goto out;
+ if (rc < 0) return;
+
+Libxenlight coding style is super simple. Avoid tricky expressions.
+
+
+5. Block structure
+
+Every indented statement is braced, but blocks that contain just one
+statement may have the braces omitted. To avoid confusion, either all
+the blocks in an if...else chain have braces, or none of them do.
+
+The opening brace is on the line that contains the control flow
+statement that introduces the new block; the closing brace is on the
+same line as the else keyword, or on a line by itself if there is no
+else keyword. Examples:
+
+ if (a == 5) {
+ printf("a was 5.\n");
+ } else if (a == 6) {
+ printf("a was 6.\n");
+ } else {
+ printf("a was something else entirely.\n");
+ }
+
+ if (a == 5)
+ printf("a was 5.\n");
+
+An exception is the opening brace for a function; for reasons of tradition
+and clarity it comes on a line by itself:
+
+ void a_function(void)
+ {
+ do_something();
+ }
+
+Rationale: a consistent (except for functions...) bracing style reduces
+ambiguity and avoids needless churn when lines are added or removed.
+Furthermore, it is the libxenlight coding style.

-LIBXENLIGHT CODING STYLE
-========================
-
-
-AN APOLOGY AND WARNING
-----------------------
-
-Much of the code in libxl does not yet follow this coding style
-document in every respect. However, new code is expected to conform.
-
-Patches to improve the style of existing code are welcome. Please
-separate these out from functional changes.
-
-If it is not feasible to conform fully to the style while patching old
-code, without doing substantial style reengineering first, we may
-accept patches which contain nonconformant elements, provided that
-they don't make the coding style problem worse overall.
-
-In this case, the new code should conform to the prevailing style in
-the area being touched.
-
-
-MEMORY ALLOCATION
------------------
-
-Memory allocation for libxl-internal purposes should normally be done
-with the provided gc mechanisms; there is then no need to free. See
-"libxl memory management" in libxl.h.
-
-
-CONVENTIONAL VARIABLE NAMES
----------------------------
-
-The following local variable names should be used where applicable:
-
- int rc; /* a libxl error code - and not anything else */
- int r; /* the return value from a system call (or libxc call) */
- bool ok; /* the success return value from a boolean function */
-
- uint32_t domid;
- libxl__gc *gc;
- libxl__egc *egc;
- libxl__ao *ao;
-
- libxl_foo_bar_state *fbs; /* local variable */
- libxl_foo_bar_state foo_bar; /* inside another state struct */
-
-
-CONVENIENCE MACROS
-------------------
-
-There are a number of convenience macros which shorten the program and
-avoid opportunity for mistakes. In some cases non-use of the macros
-produces functional bugs or incorrect error handling. Use the macros
-whenever they are applicable. For example:
-
- Usually, don't use: Instead, use (see libxl_internal.h):
- libxl__log[v] LOG, LOGE, LOGEV
- libxl__sprintf GCSPRINTF
- libxl__*alloc et al. GCNEW, GCNEW_ARRAY, GCREALLOC_ARRAY
- isalnum etc. directly CTYPE
- libxl__ctx_[un]lock CTX_LOCK, CTX_UNLOCK
- gc=...; ao=...; EGC_GC, AO_GC, STATE_AO_GC
- explicit gc creation GC_INIT, GC_FREE
- memset(..,0,sizeof..) FILLZERO
-
-Instead of malloc et al one should (as an exception to the above) use
-libxl__{zalloc,calloc,realloc} etc but passing NOGC.
-
-ERROR HANDLING
---------------
-
-Unless, there are good reasons to do otherwise, the following error
-handling and cleanup paradigm should be used:
-
- * All local variables referring to resources which might need
- cleaning up are declared at the top of the function, and
- initialised to a sentinel value indicating "nothing allocated".
- For example,
- libxl_evgen_disk_eject *evg = NULL;
- int nullfd = -1;
-
- * If the function is to return a libxl error value, `rc' is
- used to contain the error code, but it is NOT initialised:
- int rc;
-
- * There is only one error cleanup path out of the function. It
- starts with a label `out:'. That error cleanup path checks for
- each allocated resource and frees it iff necessary. It then
- returns rc. For example,
- out:
- if (evg) libxl__evdisable_disk_eject(gc, evg);
- if (nullfd >= 0) close(nullfd);
- return rc;
-
- * Function calls which might fail (ie most function calls) are
- handled by putting the return/status value into a variable, and
- then checking it in a separate statement:
- char *dompath = libxl__xs_get_dompath(gc, bl->domid);
- if (!dompath) { rc = ERROR_FAIL; goto out; }
-
- * If a resource is freed in the main body of the function (for
- example, in a loop), the corresponding variable has to be reset to
- the sentinel at the point where it's freed.
-
-Whether to use the `out' path for successful returns as well as error
-returns is a matter of taste and convenience for the specific
-function. Not reusing the out path is fine if the duplicated function
-exit code is only `CTX_UNLOCK; GC_FREE;' (or similar).
-
-If you reuse the `out' path for successful returns, there may be
-resources which are to be returned to the caller rather than freed.
-In that case you have to reset the local variable to `nothing here',
-to avoid the resource being freed on the out path. That resetting
-should be done immediately after the resource value is stored at the
-applicable _r function parameter (or equivalent). Do not test `rc' in
-the out section, to discover whether to free things.
-
-The uses of the single-line formatting in the examples above are
-permitted exceptions to the usual libxl code formatting rules.
-
-
-
-IDEMPOTENT DATA STRUCTURE CONSTRUCTION/DESTRUCTION
---------------------------------------------------
-
-Nontrivial data structures (in structs) should come with an idempotent
-_dispose function, which must free all resources associated with the
-data structure (but not free the struct itself).
-
-Such a struct should also come with an _init function which
-initialises the struct so that _dispose is a no-op.
-
-
-ASYNCHRONOUS/LONG-RUNNING OPERATIONS
-------------------------------------
-
-All long-running operations in libxl need to use the asynchronous
-operation machinery. Consult the programmer documentation in
-libxl_internal.h for details - search for "Machinery for asynchronous
-operations".
-
-The code for asynchronous operations should be laid out in
-chronological order. That is, where there is a chain of callback
-functions, each subsequent function should be, textually, the next
-function in the file. This will normally involve predeclaring the
-callback functions. Synchronous helper functions should be separated
-out into a section preceding the main callback chain.
-
-Control flow arrangements in asynchronous operations should be made as
-simple as possible, because it can otherwise be very hard to see
-through the tangle.
-
-
-When inventing a new sub-operation in asynchronous code, consider
-whether to structure it formally as a sub-operation with its own state
-structure. (See, for example, libxl__datacopier_*.)
-
-An ao-suboperation state structure should contain, in this order:
- * fields that the caller must fill in, and which are,
- effectively, the parameters to the operation, including:
- - libxl__ao *ao
- - the callback function pointer(s), which
- should be named callback or callback_*.
- * shared information fields or ones used for returning information
- to the calling operation
- * private fields
-These sections should be clearly demarcated by comments.
-
-An asynchronous operation should normally have an idempotent stop or
-cancel function. It should normally also have an _init function for
-its state struct, which arranges that the stop is a no-op.
-
-The permitted order of calls into your ao operation's methods must be
-documented in comments, if it is nontrivial.
-
-
-When using an ao sub-operation, you should normally:
- * Physically include the sub-operation state struct in your
- own state struct;
- * Use CONTAINER_OF to find your own state struct at the start of
- your implementations of the sub-operation callback functions;
- * Unconditionally initialise the sub-operation's struct (with its
- _init method) in your own _init method.
- * Unconditionally cancel or destroy the sub-operation in your own
- cancel or destroy method.
-
-
-FORMATTING AND NAMING
----------------------
-
-Blatantly copied from qemu and linux with few modifications.
-
-
-1. Whitespace
-
-Of course, the most important aspect in any coding style is whitespace.
-Crusty old coders who have trouble spotting the glasses on their noses
-can tell the difference between a tab and eight spaces from a distance
-of approximately fifteen parsecs. Many a flamewar have been fought and
-lost on this issue.
-
-Libxenlight indents are four spaces. Tabs are never used, except in
-Makefiles where they have been irreversibly coded into the syntax.
-Spaces of course are superior to tabs because:
-
- - You have just one way to specify whitespace, not two. Ambiguity breeds
- mistakes.
- - The confusion surrounding 'use tabs to indent, spaces to justify' is gone.
- - Tab indents push your code to the right, making your screen seriously
- unbalanced.
- - Tabs will be rendered incorrectly on editors who are misconfigured not
- to use tab stops of eight positions.
- - Tabs are rendered badly in patches, causing off-by-one errors in almost
- every line.
- - It is the libxenlight coding style.
-
-Do not leave whitespace dangling off the ends of lines.
-
-
-2. Line width
-
-Lines are limited to 75 characters.
-
-Rationale:
- - Some people like to tile their 24" screens with a 6x4 matrix of 80x24
- xterms and use vi in all of them. The best way to punish them is to
- let them keep doing it.
- - In an 80 column terminal, some room needs to be left for > quoting
- characters, +/- diff characters, and so on, in emails.
- - Code and especially patches is much more readable if limited to a sane
- line length. Eighty is traditional.
- - It is the libxenlight coding style.
-
-
-3. Naming
-
-C is a Spartan language, and so should your naming be. Unlike Modula-2
-and Pascal programmers, C programmers do not use cute names like
-ThisVariableIsATemporaryCounter. A C programmer would call that
-variable "tmp", which is much easier to write, and not the least more
-difficult to understand.
-
-HOWEVER, while mixed-case names are frowned upon, descriptive names for
-global variables are a must. To call a global function "foo" is a
-shooting offense.
-
-GLOBAL variables (to be used only if you _really_ need them) need to
-have descriptive names, as do global functions. If you have a function
-that counts the number of active users, you should call that
-"count_active_users()" or similar, you should _not_ call it "cntusr()".
-
-Encoding the type of a function into the name (so-called Hungarian
-notation) is brain damaged - the compiler knows the types anyway and can
-check those, and it only confuses the programmer.
-
-LOCAL variable names should be short, and to the point. If you have
-some random integer loop counter, it should probably be called "i".
-Calling it "loop_counter" is non-productive, if there is no chance of it
-being mis-understood. Similarly, "tmp" can be just about any type of
-variable that is used to hold a temporary value.
-
-Local variables used to store return values should have descriptive name
-like "rc" or "ret". Following the same reasoning the label used as exit
-path should be called "out".
-
-Function arguments which are used to return values to the caller
-should be suffixed `_r' or `_out'.
-
-Variables, type names and function names are
-lower_case_with_underscores.
-Type names and function names use the prefix libxl__ when internal to
-libxenlight and libxl_ when exported in libxl.h.
-Xl should avoid using libxl_ and libxl__ as prefix for its own function
-names.
-
-When wrapping standard library functions, use the prefix libxl_ to alert
-readers that they are seeing a wrapped version; otherwise avoid this prefix.
-
-Typedefs are used to eliminate the redundant 'struct' keyword.
-It is the libxenlight coding style.
-
-
-4. Statements
-
-Don't put multiple statements on a single line.
-Don't put multiple assignments on a single line either.
-Error code paths with an if statement and a goto or a return on the same
-line are allowed. Examples:
-
- if (rc) goto out;
- if (rc < 0) return;
-
-Libxenlight coding style is super simple. Avoid tricky expressions.
-
-
-5. Block structure
-
-Every indented statement is braced, but blocks that contain just one
-statement may have the braces omitted. To avoid confusion, either all
-the blocks in an if...else chain have braces, or none of them do.
-
-The opening brace is on the line that contains the control flow
-statement that introduces the new block; the closing brace is on the
-same line as the else keyword, or on a line by itself if there is no
-else keyword. Examples:
-
- if (a == 5) {
- printf("a was 5.\n");
- } else if (a == 6) {
- printf("a was 6.\n");
- } else {
- printf("a was something else entirely.\n");
- }
-
- if (a == 5)
- printf("a was 5.\n");
-
-An exception is the opening brace for a function; for reasons of tradition
-and clarity it comes on a line by itself:
-
- void a_function(void)
- {
- do_something();
- }
-
-Rationale: a consistent (except for functions...) bracing style reduces
-ambiguity and avoids needless churn when lines are added or removed.
-Furthermore, it is the libxenlight coding style.
