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. + diff --git a/tools/libs/util/Makefile b/tools/libs/util/Makefile new file mode 100644 index 0000000000..0c9db8027d --- /dev/null +++ b/tools/libs/util/Makefile @@ -0,0 +1,63 @@ +XEN_ROOT = $(CURDIR)/../../.. +include $(XEN_ROOT)/tools/Rules.mk + +SRCS-y += libxlu_cfg_y.c +SRCS-y += libxlu_cfg_l.c +SRCS-y += libxlu_cfg.c +SRCS-y += libxlu_disk_l.c +SRCS-y += libxlu_disk.c +SRCS-y += libxlu_vif.c +SRCS-y += libxlu_pci.c + +CFLAGS += -Wno-format-zero-length -Wmissing-declarations \ + -Wno-declaration-after-statement -Wformat-nonliteral +CFLAGS += -I. $(CFLAGS_libxenctrl) + +CFLAGS += $(PTHREAD_CFLAGS) +LDFLAGS += $(PTHREAD_LDFLAGS) + +ifeq ($(FLEX),) +%.c %.h:: %.l + $(warning Flex is needed to rebuild some libxl parsers and \ + scanners, please install it and rerun configure) +endif + +ifeq ($(BISON),) +%.c %.h:: %.y + $(warning Bison is needed to rebuild some libxl parsers and \ + scanners, please install it and rerun configure) +endif + +AUTOINCS = libxlu_cfg_y.h libxlu_cfg_l.h libxlu_disk_l.h +AUTOSRCS = libxlu_cfg_y.c libxlu_cfg_l.c + +LIBHEADER := libxlutil.h +PKG_CONFIG_NAME := Xlutil +PKG_CONFIG_DESC := The xl utility library for Xen hypervisor + +NO_HEADERS_CHK := y + +include $(XEN_ROOT)/tools/libs/libs.mk + +$(PKG_CONFIG_LOCAL): PKG_CONFIG_INCDIR = $(XEN_libxenutil)/include +$(PKG_CONFIG_LOCAL): PKG_CONFIG_CFLAGS_LOCAL = $(CFLAGS_xeninclude) + +$(LIB_OBJS) $(PIC_OBJS): $(AUTOINCS) _paths.h + +%.c %.h:: %.y + @rm -f $*.[ch] + $(BISON) --output=$*.c $< + +%.c %.h:: %.l + @rm -f $*.[ch] + $(FLEX) --header-file=$*.h --outfile=$*.c $< + +genpath-target = $(call buildmakevars2header,_paths.h) +$(eval $(genpath-target)) + +clean: cleanlocal + +.PHONY: cleanlocal +cleanlocal: + $(RM) -f _*.h + $(RM) -f libxlutil.map diff --git a/tools/libs/util/include/libxlutil.h b/tools/libs/util/include/libxlutil.h new file mode 100644 index 0000000000..92e35c5462 --- /dev/null +++ b/tools/libs/util/include/libxlutil.h @@ -0,0 +1,136 @@ +/* + * Copyright (C) 2010 Citrix Ltd. + * Author Ian Jackson + * + * This program 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; version 2.1 only. with the special + * exception on linking described in file LICENSE. + * + * This program 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.

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. - diff --git a/tools/libxl/Makefile b/tools/libxl/Makefile deleted file mode 100644 index 51da1d5be4..0000000000 --- a/tools/libxl/Makefile +++ /dev/null @@ -1,124 +0,0 @@ -# -# tools/libxl/Makefile -# - -XEN_ROOT = $(CURDIR)/../.. -include $(XEN_ROOT)/tools/Rules.mk - -XLUMAJOR = 4.15 -XLUMINOR = 0 - -CFLAGS += -Werror -Wno-format-zero-length -Wmissing-declarations \ - -Wno-declaration-after-statement -Wformat-nonliteral -CFLAGS += -I. -fPIC - -CFLAGS += $(PTHREAD_CFLAGS) -LDFLAGS += $(PTHREAD_LDFLAGS) - -LIBXLU_LIBS = $(LDLIBS_libxenlight) - -ifeq ($(FLEX),) -%.c %.h:: %.l - $(warning Flex is needed to rebuild some libxl parsers and \ - scanners, please install it and rerun configure) -endif - -ifeq ($(BISON),) -%.c %.h:: %.y - $(warning Bison is needed to rebuild some libxl parsers and \ - scanners, please install it an rerun configure) -endif - -AUTOINCS= libxlu_cfg_y.h libxlu_cfg_l.h libxlu_disk_l.h -AUTOSRCS= libxlu_cfg_y.c libxlu_cfg_l.c -LIBXLU_OBJS = libxlu_cfg_y.o libxlu_cfg_l.o libxlu_cfg.o \ - libxlu_disk_l.o libxlu_disk.o libxlu_vif.o libxlu_pci.o -$(LIBXLU_OBJS): CFLAGS += $(CFLAGS_libxenctrl) # For xentoollog.h - -PKG_CONFIG = xlutil.pc - -ifneq ($(CONFIG_LIBXC_MINIOS),y) -PKG_CONFIG_INST := $(PKG_CONFIG) -xlutil.pc: PKG_CONFIG_NAME = Xlutil -xlutil.pc: PKG_CONFIG_DESC = The xl utility library for Xen hypervisor -xlutil.pc: PKG_CONFIG_VERSION = $(XLUMAJOR).$(XLUMINOR) -xlutil.pc: PKG_CONFIG_USELIBS = $(SHLIB_libxenutil) -xlutil.pc: PKG_CONFIG_LIB = xlutil -xlutil.pc: PKG_CONFIG_REQPRIV = xenlight -$(PKG_CONFIG_INST): PKG_CONFIG_PREFIX = $(prefix) -$(PKG_CONFIG_INST): PKG_CONFIG_INCDIR = $(includedir) -$(PKG_CONFIG_INST): PKG_CONFIG_LIBDIR = $(libdir) -endif - -PKG_CONFIG_LOCAL := $(foreach pc,$(PKG_CONFIG),$(PKG_CONFIG_DIR)/$(pc)) - -$(PKG_CONFIG_DIR)/xlutil.pc: PKG_CONFIG_NAME = Xlutil -$(PKG_CONFIG_DIR)/xlutil.pc: PKG_CONFIG_DESC = The xl utility library for Xen hypervisor -$(PKG_CONFIG_DIR)/xlutil.pc: PKG_CONFIG_VERSION = $(XLUMAJOR).$(XLUMINOR) -$(PKG_CONFIG_DIR)/xlutil.pc: PKG_CONFIG_USELIBS = $(SHLIB_libxenutil) -$(PKG_CONFIG_DIR)/xlutil.pc: PKG_CONFIG_LIB = xlutil -$(PKG_CONFIG_DIR)/xlutil.pc: PKG_CONFIG_REQPRIV = xenlight -$(PKG_CONFIG_LOCAL): PKG_CONFIG_PREFIX = $(XEN_ROOT) -$(PKG_CONFIG_LOCAL): PKG_CONFIG_INCDIR = $(CURDIR) -$(PKG_CONFIG_LOCAL): PKG_CONFIG_LIBDIR = $(CURDIR) -$(PKG_CONFIG_LOCAL): PKG_CONFIG_CFLAGS_LOCAL = $(CFLAGS_xeninclude) - -.PHONY: all -all: libxlutil.so libxlutil.a $(AUTOSRCS) $(AUTOINCS) $(PKG_CONFIG) $(PKG_CONFIG_LOCAL) - -$(LIBXLU_OBJS): $(AUTOINCS) - -%.c %.h:: %.y - @rm -f $*.[ch] - $(BISON) --output=$*.c $< - -%.c %.h:: %.l - @rm -f $*.[ch] - $(FLEX) --header-file=$*.h --outfile=$*.c $< - -genpath-target = $(call buildmakevars2header,_paths.h) -$(eval $(genpath-target)) - -libxlutil.so: libxlutil.so.$(XLUMAJOR) - $(SYMLINK_SHLIB) $< $@ - -libxlutil.so.$(XLUMAJOR): libxlutil.so.$(XLUMAJOR).$(XLUMINOR) - $(SYMLINK_SHLIB) $< $@ - -libxlutil.so.$(XLUMAJOR).$(XLUMINOR): $(LIBXLU_OBJS) - $(CC) $(LDFLAGS) -Wl,$(SONAME_LDFLAG) -Wl,libxlutil.so.$(XLUMAJOR) $(SHLIB_LDFLAGS) -o $@ $(LIBXLU_OBJS) $(LIBXLU_LIBS) $(APPEND_LDFLAGS) - -libxlutil.a: $(LIBXLU_OBJS) - $(AR) rcs libxlutil.a $^ - -.PHONY: install -install: all - $(INSTALL_DIR) $(DESTDIR)$(libdir) - $(INSTALL_DIR) $(DESTDIR)$(includedir) - $(INSTALL_SHLIB) libxlutil.so.$(XLUMAJOR).$(XLUMINOR) $(DESTDIR)$(libdir) - $(SYMLINK_SHLIB) libxlutil.so.$(XLUMAJOR).$(XLUMINOR) $(DESTDIR)$(libdir)/libxlutil.so.$(XLUMAJOR) - $(SYMLINK_SHLIB) libxlutil.so.$(XLUMAJOR) $(DESTDIR)$(libdir)/libxlutil.so - $(INSTALL_DATA) libxlutil.a $(DESTDIR)$(libdir) - $(INSTALL_DATA) libxlutil.h $(DESTDIR)$(includedir) - $(INSTALL_DATA) xlutil.pc $(DESTDIR)$(PKG_INSTALLDIR) - -.PHONY: uninstall -uninstall: - rm -f $(DESTDIR)$(PKG_INSTALLDIR)/xlutil.pc - rm -f $(DESTDIR)$(includedir)/libxlutil.h - rm -f $(DESTDIR)$(libdir)/libxlutil.a - rm -f $(DESTDIR)$(libdir)/libxlutil.so - rm -f $(DESTDIR)$(libdir)/libxlutil.so.$(XLUMAJOR) - rm -f $(DESTDIR)$(libdir)/libxlutil.so.$(XLUMAJOR).$(XLUMINOR) - -.PHONY: clean -clean: - $(RM) -f _*.h *.o *.so* *.a $(DEPS_RM) - $(RM) -f xlutil.pc - -distclean: clean - -realclean: distclean - $(RM) -f $(AUTOSRCS) $(AUTOINCS) - --include $(DEPS_INCLUDE) diff --git a/tools/libxl/libxlu_cfg.c b/tools/libxl/libxlu_cfg.c deleted file mode 100644 index 874f5abfb9..0000000000 --- a/tools/libxl/libxlu_cfg.c +++ /dev/null @@ -1,712 +0,0 @@ -/* - * libxlu_cfg.c - xl configuration file parsing: setup and helper functions - * - * Copyright (C) 2010 Citrix Ltd. - * Author Ian Jackson - * - * This program is free software;
