2015-04-29Add missing #include <stdint.h> for SIZE_MAXTodd C. Miller
2015-04-25add check for overflow while doubling (very unlikely in practice, but stillMarc Espie
better style code). Problem noticed by deraadt@ in m4. okay doug@ deraadt@
2012-11-07say goodbye to killing trailing spaces.Marc Espie
this was yet another weirdness in our make that isn't shared by other makes, and that isn't part of any standard. This means end-of-line spaces in variables ARE significant (spaces around the equal sign still aren't). okay sthen@, "sounds fine" deraadt@
2012-09-21major overhaul of the way make handle jobs, inspired by dpb:Marc Espie
instead of forking a "job" per target, and having that job further fork separate commands, have make maintain a list of jobs, indexed by pid of currently running commands, and handle process termination continuation-style. This has lots of benefits: - make is responsible for most printing, so we no longer need pipes nor job control: make -j jobs see the tty. - no more special-casing for jobs that don't really execute anything. - unify code for make -jn and make -B, including signal handlers and job waiting. So make -n, make -q, +cmd now run commands in the same way in all cases. - unified more accurate error-reporting, as make knows precisely which command failed. Commands are tagged with their lines, and we display failing commands in silent mode. - fine-grained "expensive" command handling (recursion limiter). Do it per-command instead of per-target. Moreover, signal response is now simpler, as we just block the signals in a small critical sections, test for events, and sigpause (thanks a lot to guenther@ and millert@), so running make is now almost always paused without any busy-waiting. Thanks to everyone who tested and gave input.

2010-07-19two small changes:Marc Espie
- allow variables in SysV modifiers, as requested by matthieu@ (since recursive variables are an extension, this just extends the extension) - variation on :Q called :QL (quote list), which does quote every character EXCEPT for whitespace. e.g., toto: @for i in ${VAR:QL} ...
2007-07-24reindent (no binary change)Marc Espie
2004-04-07ISO function declarations, trim a few comments, rename a few variables toMarc Espie
more explicit/more consistent names. okay otto@
2003-06-03Remove the advertising clause in the UCB license which BerkeleyTodd C. Miller
rescinded 22 July 1999. Proofed by myself and Theo.
2001-05-30-Wall cleanup, mostly useless otherwiseTheo de Raadt
2001-05-29Blech! gcc is a stupid program. Compiling with -fno-builtin shows lotsMarc Espie
of missing function declarations.
2001-05-23Mostly clean-up:Marc Espie
- cut up those huge include files into separate interfaces for all modules. Put the interface documentation there, and not with the implementation. - light-weight includes for needed concrete types (lst_t.h, timestamp_t.h). - cut out some more logically separate parts: cmd_exec, varname, parsevar, timestamp. - put all error handling functions together, so that we will be able to clean them up. - more systematic naming: functioni to handle interval, function to handle string. - put the init/end code apart to minimize coupling. - kill weird types like ReturnStatus and Boolean. Use standard bool (with a fallback for non-iso systems) - better interface documentation for lots of subsystems. As a result, make compilation goes somewhat faster (5%, even considering the largish BSD copyrights to read). The corresponding preprocessed source goes down from 1,5M to 1M. A few minor code changes as well: Parse_DoVar is no longer destructive. Parse_IsVar functionality is folded into Parse_DoVar (as it knows what an assignment is), a few more interval handling functions. Avoid calling XXX_End when they do nothing, just #define XXX_End to nothing. Parse_DoVar is slightly more general: it will handle compound assignments as long as they make sense, e.g., VAR +!= cmd will work. As a side effect, VAR++=value now triggers an error (two + in assignment). - this stuff doesn't occur in portable Makefiles. - writing VAR++ = value or VAR+ +=value disambiguates it. - this is a good thing, it uncovered a bug in bsd.port.mk. Tested by naddy@. Okayed millert@. I'll handle the fallback if there is any. This went through a full make build anyways, including isakmpd (without mickey's custom binutils, as he didn't see fit to share it with me).
2001-05-03Synch with my current work.Marc Espie
Numerous changes: - generate can build several tables - style cleanup - statistics code - use variable names throughout (struct Name) - recursive variables everywhere - faster parser (pass buffer along instead of allocating multiple copies) - correct parser. Handles comments everywhere, and ; correctly - more string intervals - simplified dir.c, less recursion. - extended for loops - sinclude() - finished removing extra junk from Lst_* - handles ${@D} and friends in a simpler way - cleaned up and modular VarModifiers handling. - recognizes some gnu Makefile usages and errors out about them. Additionally, some extra functionality is defined by FEATURES. The set of functionalities is currently hardcoded to OpenBSD defaults, but this may include support for some NetBSD extensions, like ODE modifiers. Backed by miod@ and millert@, who finally got sick of my endless patches...
2000-11-24Clean-ups:Marc Espie
* Buf_Destroy can be a macro * X_ instead of _X for struct names, to avoid infringing on the system's namespace. * better wildcard detection heuristics * fix #ifdef CLEANUP code * a few comments
2000-09-14Some systematic clean-up.Marc Espie
- UNUSED macro that expands to __attribute__((unused)) for gcc - move rcsid around so that they can be tagged UNUSED. - activate -Wunused. - use UNUSED instead of kludgy junk for function arguments. - add extern to all extern prototypes. - update comments in lst.h. - clean up var.c a little bit, constifying arguments, updating comments...
1999-12-16Allocate buffers as static data structures.Marc Espie
This cuts down quite a lot of malloc, since in actual use, buffer usage is mostly static.
1999-12-16Remove redundant fields from struct Buffer.Marc Espie
1999-12-16Split Buf_GetAll into Buf_Retrieve/Buf_Size.Marc Espie
(idiotic to retrieve size every time when it's used half the time)
1999-12-16Start cleaning up buf.c in earnest.Marc Espie
- Buf_Discard is only used to remove all the bytes in a buffer, replace with Buf_Reset, - buffer values are not read unless accessed first through Buf_GetAll, no need to null-terminate it at every point. - Buf_Expand need not check if the expansion is needed. That's Buf_AddChar and Buf_AddChars responsability (otherwise, Buf_AddChar checks twice) - Buf_Overflow only handles overflow. Adding the character is done in every case anyway.
1999-12-06Clean up buffers interface somewhat:Marc Espie
- buf.c deals exclusively with chars. Be explicit about it, and remove extraneous dumb casts to char (can hide real type errors). - buffer sizes are size_t. Note that bp->left can never become NULL. - Buf_GetAll is happy with a NULL pointer for the size, remove unneeded extra pointers. - Propagate size_t to all places where buffer functions are used.
1999-10-05Kill unused functions Buf_UngetByte, Buf_UngetBytes, Buf_GetByte, Buf_GetBytes.Marc Espie
Replace the buffer reallocation mechanism with something much more efficient. Originally from NetBSD. Tweaks to the allocator to first loop finding the correct size, then reallocate; change the heuristic to double the size until we're over what's needed by some fixed amount.
1998-12-05Modifications from netbsd:Marc Espie
- don't interfere with MACHINE/MACHINE_ARCH defines for bootstrap - type clean-up, time_t, and printing `unknown' ints - fix TARGET/MEMBER bug in archive rules - memmove... - cleaner Error handler. - reentrant brk_string - .MAKE env variable - preliminary scaffolding for .NOPATH Other improvements: - efree - shellneed streamlined - display Stop in .CURDIR after an error. - document most features and misfeatures. - add a few OpenBSD notes to the tutorial.
1997-04-01Sync with NetBSD (mostly by christos initial substitution/regexp from Der Mouse)Todd C. Miller
- fix the variable substitution code in make [PR/2748] 1. change s/a/b/ so that it substitutes the first occurance of the pattern on each word, not only the first word. 2. add flag '1' to the variable substitution so that the substitutions get performed only once. ***THIS IS AN INCOMPATIBLE CHANGE!*** Unfortunately there was no way to make things consistent without modifying the current behavior. Fortunately none of our Makefiles depended on this. OLD: VAR = aa1 aa2 aa3 aa4 S/a/b/ = ba1 aa2 aa3 aa4 S/a/b/g = bb1 bb2 bb3 bb4 NEW: VAR = aa1 aa2 aa3 aa4 S/a/b/ = ba1 ba2 ba3 ba4 S/a/b/1 = ba1 aa2 aa3 aa4 S/a/b/g = bb1 bb2 bb3 bb4 S/a/b/1g = bb1 aa2 aa3 aa4 - add regexp variable substitution via 'C/foo/bar/' [PR/2752] - add variable quoting via the ${VAR:Q} modifier. This is useful when running recursive invocations of make(1): make VAR=${VAR:Q} will always work... (This may prove useful in the kernel builds...) [PR/2981] - BSD did not traditionally have <sys/cdefs.h>; use BSD4_4 instead and include <sys/param.h> to grab it. - Don't compile the regex code if MAKE_BOOTSTRAP (from gwr) - Use explicit .c.o rule in Makefile.boot so that the bootstrap process works. - Use only integral types in procedure arguments. [buf.c buf.h] - Include <stdlib.h> to get getenv() prototype on SVR4 - if __STDC__ -> ifdef __STDC__ to appease SVR4 - Define const and volatile for non __STDC__ - Implement snprintf() and vsnprintf() for non BSD4_4 systems. - Make $MACHINE_ARCH settable from the environment. - Fix .USE directive problems: (reported by cgd) 1. ${.*} variables did not get expanded in dependencies. 2. expanded ${.*} variables in .USE dependencies can cause tree restructuring; handle it. 3. in compat mode, expand .USE before evaluating the list of targets, instead of doing .USE expansions on demand, because they can cause tree restructuring. - Add a .MADE directive to indicated that the children of a target are up-to-date, even when they are not. This is to simulate our current make install behavior with proper dependencies. - Fix problems in the RE substitution error handling. - Locate all the children of a node marked as MADE. - Do not compile-in ${MACHINE} (as per NetBSD PR#3386) - Disable globbing for targets/dependencies when POSIX is defined. - Fix globbing so that patterns that don't have a matching number of [] or {} don't get expanded. (before the [ case got expanded to nothing!) This is disabled. - Make sure that the children of nodes that are marked .MADE, are marked UPTODATE and their timestamps are consistent. - Don't disable wildcards completely; they are used by other Makefiles.
1996-11-30Sync with NetBSD:Todd C. Miller
- Merge in FreeBSD and Lite2 changes. - Fix bug where a non-archive target with a .a suffix would always be considered to be out of date, since it does not have a TOC. - Fix NetBSD PR #2930: declare missing variable.
