make: prevent future out-of-bounds errors when parsing expressions
A modifier in an expression ends not only at the next ':' or at the
closing '}' or ')', but also at the end of the string.
Previously, testing for the end of the string had been done separately,
which was error-prone since 2006-05-11, when indirect modifiers were
introduced. Since then, it was possible that the string terminator '\0'
was accidentally skipped in cases where the loop condition only tested
for the ending character. When parsing indirect modifiers, the ending
character is indeed '\0', but when parsing direct modifiers, it is '}'
or ')'.
A welcome side effect is that in the case of unclosed expressions such
as '${VAR:Modifier', the amount of error messages is reduced from 2 or 3
to only 1. The removed error messages were wrong and thus confusing
anyway.

make: revert parsing of modifier parts (since 2022-08-08)
The modifier ':@var@body@' parses the body in parse-only mode and later
uses Var_Subst on it, in which each literal '$' must be written as '$$'.
Trying to parse the loop body using Var_Parse treated the text
'$${var:-0}' as a single '$' followed by the expression '${var:-0}',
wrongly complaining about the 'Unknown modifier "-0"'.

make: when parsing ':D' or ':U', only copy text if necessary
When parsing the expression ${:D any ${uninterpreted} text}, parsing of
the ':D' modifier only needs to skip to the next delimiter, there is no
need to keep record of the text that has been skipped. In this
particular example, there had been an unnecessary memory allocation
since the nested expression was not copied to the result buffer. Due to
that, the resulting buffer contained " any text", which was not a
substring of the text passed to the parser, thereby forcing the memory
allocation.
No functional change.

make: prefer 'long long' over 'long' on 32-bit C99 platforms When sorting the words of an expression numerically using the modifier ':On' (added on 2021-07-30), use 64-bit numbers even on 32-bit platforms. A typical use case is comparing file sizes. When tracing the execution of jobs, fix an integer overflow after 2038. 32-bit platforms that use a pre-C99 compiler still have this problem. No change to the test suite since most tests simply skip any potential differences between 32-bit platforms and 64-bit platforms (see varmod-order-numeric.mk) or already account for both variants (see varmod-localtime.mk).

make: remove comment about environment variable with empty name At least on NetBSD, make cannot be fooled with an environment variable having an empty name. When running '/usr/bin/env =undefined make', the argument is parsed as a variable assignment, but putenv(3) refuses to process an empty variable name. Calling execve(2) directly got a step further, the kernel didn't filter '=undefined' from the environment variables. But getenv(3) always returns NULL when querying the environment variable with the empty name. On other operating systems, things may be different. Trying to set an environment variable with an empty name may cause errors in env(1), putenv(3), execve(2), getenv(3) or other places, so don't add an automatic test for now.

make: use fixed type for comparing numbers using the modifier ':On' When the modifier ':On' was added on 2021-07-30, there were concerns that pre-C99 environments would not have the type 'long long', therefore the type was made configurable, but parsing such numbers was hard-coded to using strtoll. To improve compatibility with C90 environments, use 'long' and 'strtol' in these environments. In C99 environments, use 'long long' and 'strtoll', to account for larger file sizes. If the flexibility of choosing yet another type for these numbers should ever arise, it can still be implemented. Until then, reduce the number of possible build configurations.

It would be possible to get more detailed location information by counting the number of commands of the target, but that would get messy due to .USEBEFORE, .USE and .DEFAULT, and still, this is an edge case, so don't waste too much code for it now. Having this hint about the location is more helpful than just a plain "Variable X is recursive" without any further details.

make: fix types for modifier ':O' (since today) In var.c 1.962 from 2021-12-05, the type of the array to be sorted changed from 'const char *' to 'Substring'. The code still worked since the first member of Substring is 'const char *start', but that was pure luck. Fix the type assumptions in the comparison functions. Add an assertion that the words must be null-terminated since the comparison functions currently assume this. This kind of inconsistency may be possible to detect using static analysis, but NetBSD's lint is currently too limited for that. To detect this, it would have to analyze each possible comparison function and remember the assumed type. This type could then be compared to the argument type of a function call to qsort or bsearch. No functional change.

make: fix lint warnings The string functions from str.h are declared as 'static __unused' when compiled with GCC, but lint explicitly undefines __GCC__ during preprocessing. Therefore, make those functions inline, to prevent warnings that they are unused. The macro UNCONST is used in a few places, and (again) since lint undefines __GCC__, that macro expanded to a simple type cast, which lint warned about. To prevent this warning, implement UNCONST as a function that works everywhere and hides the type cast. In filemon_open, the code for closing F->in was obviously unreachable. No functional change.

make: use straight quotes for error 'Bad conditional expression' This diagnostic was supposed to be an error, see ApplyModifier_IfElse. When such an error occurs while the makefiles are read, make stops with an error, as can be expected. But when such an error occurs later, after all makefiles have been read, the message is printed but make does not stop. In lint mode (-dL), make stops in such a case. I didn't dare to make this the default behavior, out of fear of breaking existing build infrastructure, not only in NetBSD or pkgsrc, but also FreeBSD and other operating systems that use the bmake distribution, generated from the same source code.

make: reduce memory allocation and strlen calls in modifier ':from=to' Previously, SysVMatch was quite verbose and felt like hand-optimized assembler code, which made it difficult to discover the underlying idea of the code. All this code was replaced with two simple calls to Substring_HasPrefix and Substring_HasSuffix. Now that the operands of that modifier are no longer passed as C strings, there is no need to collect all information in a single scan through the word and the pattern. It was not necessary to call Var_Subst unconditionally. Calling it only when the string contains a '$' saves another memory allocation and two string copies (because of the Buf_DoneDataCompact). No functional change.

make: improve performance for LazyBuf The previous O(n^2) time complexity for parsing a long string with many variable expressions was not meant to last for long. I had hoped to fix it within a few minutes, but that will take more time. For now, make LazyBuf simpler by using a traditional C string for the expected part instead of a Substring. This avoids a strlen call per Var_Parse. No functional change, only performance.

make: migrate ModifyWord functions to use Substring This benefits the modifiers ':T' and ':H' since these scan the word from the end. The SysV modifier '.c=.o' does not benefit yet, this will be done in a follow-up commit. Currently ModifyWords calls strlen for each single word, which degrades performance. This will be cleaned up in a follow-up commit as well. No functional change.

When the word passed to the ModifyWord functions is converted to Substring as well, the call to strlen will become redundant. No functional change.

make: avoid allocating memory for simple variable names The main change is in ParseVarname, where a Buffer is replaced with the newly introduced LazyBuf. LazyBuf is inspired by https://golang.org/src/path/path.go. In CanonicalVarname, the pre-comparison of the first letter of the variable name is no longer necessary. GCC 9 optimizes a fixed-length memcmp so well that the code can finally be written to target human readers, leaving the optimization to the compiler.

The two flags that could be combined were keepDollar and keepUndef, but even these have distinguished names in the debug log. The downside of struct bit-fields is that they need extra helper functions in C90 (see nonints.h). Exchange these for a few helper functions in var.c, to keep the code outside var.c simple.

make: fix double varname expansion in the variable modifier '::='
This is an edge case that doesn't occur in practice since pretty much
nobody dares to use variable names that contain an actual '$' in their
name. This is not about the fairly common VAR.${param} (as written in
the makefile), but instead about the variable whose name is literally
'VAR.${param}'.
The test demonstrates that after the fix, the variable name is taken
exactly as-is for the simple assignment modifier '::='. There are no
such tests for the modifiers '::+=', '::!=' and '::?=', but that's ok.
The code in ApplyModifier_Assign would look assymetrical and suspicious
enough if one of these modifiers would expand its variable name and the
others wouldn't.

make: replace enum bit-field with struct bit-field for VarEvalFlags This makes the code easier to read, especially in var.c. It also makes debugging sessions easier since some debuggers don't show enum bit-fields symbolically as soon as more than one bit is set. The code outside var.c is basically unchanged, except that instead of passing the individual flags, there are 4 predefined evaluation modes. These suffice for all practical use cases. Only in the implementation deep inside var.c, the value of the flags keepDollar and keepUndef differs. There is no way of passing the struct to EnumFlags_ToString, which means the ToString function has to be spelled out explicitly. This allows for fine-tuning the representation in the debug log, to reduce the amount of uppercae letters. No functional change.

make: only evaluate the ':@' modifier if the result is actually used
The test 'var-eval-short' had produced the output 'unexpected' before,
on stderr. It had been generated by '${:Uword:@${FAIL}@expr@}' by
combining the following obscure "features" of make:
1. the ':@' modifier loops over the words of the variable. This
modifier is not really obscure, it still takes some time to get used
to it.
2. the ':@' modifier allows a '$' sign in the variable name, which is
useless in practice.
3. the ':@' modifier creates a temporary loop variable in the global
namespace. Luckily there are only few collisions with other
variable names since their naming conventions differ.
4. after looping over the words of the expression, the temporary global
loop variable is deleted, and at that point the '$' is expanded,
being interpreted as the start of a variable expression.
5. The ':@' modifier deleted the global variable even when it was
called in parse-only mode (without VARE_WANTRES).
When the modifier ':@' was initially added to make in var.c 1.40 from
2000-04-29, Var_Delete didn't expand the variable name. That feature
was added in var.c 1.174 from 2013-05-18, probably without thinking of
this very edge-casey combination of features.
This commit fixes item 5 from the above list. The other obscurities
remain for now.

make: merge duplicate code in ApplyModifier_Remember This way, parsing and evaluating the modifier is only written once in the code. The downside is that the variable name is allocated even if VARE_WANTRES is not set, but since this modifier is so obscure and seldom used this doesn't matter in practice.

make: do not expand the variable name in the ':_' modifier This edge case had been so obscure that even discovering this takes quite some time and requires reading the source code of make. The manual page doesn't document whether the variable name is expanded or not, it doesn't even give an example. When this obscure modifier was initially added in var.c 1.210 from 2017-01-30, Var_Set always expanded the variable name once, and there was no way around it. Therefore this expansion has probably been unintentional.

make: do not expand variable name from the command line twice in a row
When
1. there is a global variable containing a dollar in its expanded name
(very unlikely since there are lots of undocumented edge cases that
make variable names containing dollar signs fragile), and
2. after that (unlikely since that requires .MAKEFLAGS instead of a
normal command line)
3. there is a command line variable of the same name (again very
unlikely since that variable name would contain a dollar sign as
well in the expanded form),
the global variable would not be undefined as promised by the comments
since its name was expanded once more than intended.
Because of the two 'very unlikely' above, this edge case hopefully does
not affect any practical use cases.
Note that this is not about VAR.${param} (which has a dollar sign in its
unexpanded form), but about the case where param itself would expand to
a dollar sign, such as after param=$$.

make: sync comment about duplicated code with reality
There are only very few places in var.c that contain really duplicate
code anymore.
There is still lots of _almost_ duplicate, for example the code for
parsing variable modifiers. It differs subtly in behavior:
* The modifiers ':M' and ':N' use '$$' to escape a '$' sign, while
almost all other modifiers use '\$' for this purpose.
* The modifiers ':M', ':N', ':S', ':@' and several others parse
balanced parentheses and braces, allowing '(' to '}' to match.
The modifiers ':D' and ':U' only treat the end character special but
not the other 3 of '(){}'.
* When parsing the modifier ':S' but not evaluating it, the code for
nested variable expressions is parsed differently from when it is in
evaluation mode (VARE_WANTRES). This applies to an outer ':S'
modifier and an inner ':D' or ':M' modifier.
Since these inconsistencies affect the behavior in edge cases and some
users of make might depend on it, they cannot be fixed by
behavior-preserving refactorings.

make: rename ExprStatus to ExprDefined The type describes the definedness of an expression, not a general status, therefore the new name is more precise. The constants are renamed as well since their prefix 'VES' does not match the type name anymore, it was correct 3 days ago when the type was still named VarExprStatus. The name VES_NONE was misleading since 'none' does not describe its actual effect. That name came from the time when the status was a bit set, and 'none' simply meant 'none of the bits are set'. The names used in debug logging will be renamed in a follow-up commit, to demonstrate that the changes in this commit indeed have no functional change, especially not the change from '!=' to '==' in line 4304.

make: split parameters for evaluating variable expressions
The details of how variable expressions are evaluated is controlled by
several parameters: startc and endc differ for $(VAR) and ${VAR}, the
value of the expression can be interpreted as a single big word, and
when joining several words (such as with ':M' or ':S'), there may be a
custom word separator (defined with ':ts*').
The scope of half of these parameters is the whole variable expression,
the other half of the parameters are reset after each chain of indirect
modifiers. To make this distinction obvious in the code, extract Expr
from ApplyModifiersState. Previously, these details were hidden in how
parameters are passed and restored among ApplyModifiersIndirect and
ApplyModifiers.
The changes in the individual ApplyModifier functions are numerous but
straight-forward. They mostly replace 'st' with 'expr'.
The changes in ApplyModifiers and ApplyModifiersIndirect are more
subtle. The value of the expression is no longer passed around but is
stored in a fixed location, in Expr, which makes it easier to reason
about memory management.
The code in ApplyModifiers after 'cleanup' looks quite different but
preserves the existing behavior. Expr_SetValueRefer is nothing else
than the combination of FStr_Done followed by FStr_InitRefer. Storing
exprStatus back at the end was responsible for passing the definedness
of the expression after applying the indirect modifiers back to the
outer ApplyModifiersState. The same effect is now achieved by having
Expr.status with a wider scope.
No functional change.

make: clean up memory management in evaluation of expressions The condition "st->newValue.str != val" in ApplySingleModifier made the memory management look more complicated than it really was. Freeing an object based on another object's value is harder to understand than necessary. To fix this, the "current value" of the expression is now stored in ApplyModifiersState, and it gets updated in-place by the ApplyModifier functions. This reduces the number of parameters for the ApplyModifier functions. Accessing the current value of the expression is now more verbose than before (st->value.str instead of the simple val). To compensate for this verbosity, ApplyModifiersIndirect is now much easier to understand since there is no extra "current value" floating around. There is still room for improvement. In ApplyModifiers, passing an FStr in and returning another (or possibly the same) makes it difficult to understand memory management. Adding a separate Expr type that outlives the ApplyModifiersState will make this easier, in a follow-up commit.

make: print error about failed shell command before overwriting variable Memory management of the value of variable expressions is currently more complicated than necessary. It is the responsibility of ApplyModifiers, even though conceptually the value belongs to an expression, so it should rather be in Expr. Right now, this is an alias for ApplyModifiersState, but that will change soon. When that is done, there will no longer be a "current value" and a "new value", only a single "value" of an expression. At that point, before Expr_SetValueOwn will overwrite the old value with the output of the shell command, the error message needs to refer to the latter.

make: rename ApplyModifiersState_Define to Expr_Define The type name ApplyModifiersState was only intended as a working draft, its name is too long and its scope a little too narrow. Applying the modifiers is the main part of evaluating a variable expression, and the scope of that type will be extended to parsing the name of the expression as well. This will hopefully reduce the number of parameters, which is currently at 14. No functional change.

make: improve documentation about variable scopes In an experiment, I tried to separate the concepts of a GNode and a variable scope. The global variables SCOPE_GLOBAL, SCOPE_INTERNAL and SCOPE_CMDLINE are implemented as GNode even though they only need the members 'name' and 'vars'. All their other members are unused. Therefore it seemed natural to extract this part of the GNode into a separate type called Scope. The resulting code was harder to read though since it had split the namespace of the functions into several parts that were not obviously related: The Var_ functions, the Scope_ functions, and the short-cut Global_ functions. Because of this, I threw away the experiment. All that is left are a few updated comments.

make: rename context and ctxt to scope
This continues the previous commit, in which VAR_GLOBAL, VAR_INTERNAL
and VAR_CMDLINE were renamed.
Renaming the variable 'ctxt' was trivial since that word is used nowhere
else. In the comments though, each occurrence of the word 'context' had
to be checked individually since the word 'context' was not only used
for referring to a variable scope. It is also used to distinguish
different situations where characters are escaped in a certain way
('parsing context') and in a few other expressions.

make: rename some VAR constants to SCOPE The word "context" does not fit perfectly to the variables that are associate with a GNode, as the context is usually something from the outside and the variables are more like properties inherent to the GNode. The term "global context" fits even less. Since the thing where variables are looked up is commonly named a scope, use that term instead. This commit only renames the global variables VAR_GLOBAL, VAR_INTERNAL and VAR_CMDLINE, plus a few very closely related comments. These are: GNode.vars (because of line breaks) GNode_Free (dito) varname-make_print_var_on_error.mk varname-make_print_var_on_error-jobs.mk The debug message in Var_Stats is left as-is since there is no unit test for it yet. The other renamings (variable names "context", "ctxt", as well as further comments) will be done in a follow-up commit.

make: use shortcut functions Global_SetExpand and Global_AppendExpand There are many places where global variables are set or appended to. To reduce clutter and code size, encode the VAR_GLOBAL in the function name. The word Expand in the function names says that the variable name is expanded. In most of the cases, this is not necessary, but there are no corresponding functions Global_Set or Global_Append yet. Encoding the information whether the name is expanded or not in the function name will make inconsistencies obvious in future manual code reviews. Letting the compiler check this by using different types for unexpanded and expanded variable names is probably not worth the effort. There are still a few bugs to be fixed, such as in SetVar, which expands the variable name twice in a row.

On x86_64, memory access is no longer in 32-bit units but in 8-bit units since only the first few bits are actually used. The bit patterns are the same as before, so if there is any difference in performance, GCC should have chosen the more efficient variant all along. In a previous experiment, the code size increased a lot, surprisingly.

make(1): split Buf_Destroy into Buf_Done and Buf_DoneData In all cases except one, the boolean argument to Buf_Destroy was constant. Removing that argument by splitting the function into two separate functions makes the intention clearer on the call site. It also removes the possibility for using the return value of Buf_Done, which would have made no sense. The function Buf_Done now pairs with Buf_Init, just as in HashTable and Lst. Even though Buf_Done is essentially a no-op, it is kept as a function, both for symmetry with Buf_Init and for clearing the Buffer members after use (this will be done only in CLEANUP mode, in a follow-up commit).

make(1): consistently use boolean expressions in conditions Most of the make code already followed the style of explicitly writing (ptr != NULL) instead of the shorter (ptr) in conditions. The remaining 50 instances have been found by an experimental, unpublished check in lint(1) that treats bool expressions as incompatible to any other scalar type, just as in Java, C#, Pascal and several other languages. The only unsafe operation on Boolean that is left over is (flags & FLAG), for an enum implementing a bit set. If Boolean is an ordinary integer type (the default), some high bits may get lost. But if Boolean is the same as _Bool (by compiling with -DUSE_C99_BOOLEAN), C99 6.3.1.2 defines that a conversion from any scalar to the type _Bool acts as a comparison to 0, which cannot lose any bits.

make(1): replace global preserveUndefined with VARE_KEEP_UNDEF Controlling the expansion of variable expressions using a global variable and a VARE flag was inconsistent. Converting the global variable into a flag had to prerequisites: 1. The unintended duplicate variable assignment had to be fixed, as done in parse.c 1.520 from 2020-12-27. Without this fix, it would have been necessary to add more flags to Var_Exists and Var_SetWithFlags, and this would have become too complex. 2. There had to be a unit test demonstrating that VARE_KEEP_DOLLAR only applies to the top-level expression and is not passed to the subexpressions, while VARE_KEEP_UNDEF applies to all subexpressions as well. This test is in var-op-expand.mk 1.10 from 2020-12-28, at least for the ':@word@' modifier. In ParseModifierPartSubst, VARE_KEEP_UNDEF is not passed down either, in the same way.

make(1): clean up VarParseResult constants
The many constants were invented because at that time I didn't quite
understand the actual outcomes of Var_Parse that need to be
distinguished. There are only a few:
(1) Errors, whether they are parse errors, or evaluation errors or
undefined variables. The old constants VPR_PARSE_MSG and
VPR_UNDEF_MSG are merged into VPR_ERR.
(2) Undefined expressions in a situation in which they are allowed.
Previously the documentation for VPR_UNDEF_SILENT talked about
undefined expressions in situations where they were not allowed.
That case is fully covered by VPR_ERR instead.
(3) Errors that are silently ignored. These are probably bugs.
(4) Everything went fine, the expression has a defined value.

make(1): allow .undef to undefine multiple variables at once Since make doesn't support variable names containing spaces, this edge case is not enough reason to stop this feature. Having multiple variable names as arguments nicely aligns with other directives such as .for and .export.

make(1): switch memory handling from MFStr to FStr This makes all intermediate strings constant. For this simple search-and-replace refactoring, all intermediate locations where the "current value of the expression" was stored had to be of the type MFStr. Using FStr instead of MFStr allows to save a few memory allocations, which will be done in the follow-up commits.

make(1): clean up memory management for expanding variable expressions Previously, memory management had been split among several variables. The general idea was very simple though. The current value of the expression needs to be kept in memory, and each modifier either keeps that value or replaces it with its own newly allocated result, or var_Error or varUndefined. Using MFStr, it does not matter anymore that var_Error and varUndefined are statically allocated since these are assigned using MFStr_InitRefer. The complexity of the implementation is now closer to the actual complexity. Most probably the code can be simplified even more.

Having separate functions for the two main use cases of a possibly allocated string makes the calling code simpler. This is a preparatory commit for making the memory allocation in ApplyModifiers easier to understand.

make(1): clean up VarEvalFlags in the calls to Var_Parse and Var_Subst There are only 3 flags, and some combinations don't even make sense. VARE_UNDEFERR only makes sense if combined with VARE_WANTRES. If the latter is not set, the variable expressions are only parsed, without asking whether they are defined or not. Therefore, VARE_UNDEFERR cannot have any effect in that case. VARE_KEEP_DOLLAR is actively ignored by ParseModifierPart. In cases where VARE_WANTRES is not set, this means that VARE_NONE can be passed, which is easier to grasp than any bitset operations. This also gets rid of a few type casts from enum to unsigned int that were necessary to pass WARNS=6.

make(1): rename VARE_ASSIGN to VARE_KEEP_DOLLAR The other flags in VarEvalFlags already describe their effects, not the place where they are used. It's more important to know the effect. Only a single unit test had to be adjusted. This probably means that there are too few tests where the special effects of VARE_KEEP_DOLLAR come into play. It could also mean that the effects are so simple and obvious that they don't need any debug log, but that's not the case.

make(1): add test for undefined variables in command line arguments The variable discardUndefined has an implicit negation in its name, which makes it hard to understand. Plus, most of the time it is true. It's better to have a flag that is false most of the time and has a positive name. On the first attempt of inverting that variable, I stumbled upon MainParseArgs, which initially leaves discardUndefined == FALSE, and after handling the dashed options, sets it to TRUE. This would make a difference when more command line arguments would be added later via the .MAKEFLAGS special target. Upon further inspection, the only place where discardUndefined is used is in VarAssign_EvalSubst in parse.c, and that place is not reachable from any of the dashed options. Therefore, discardUndefined could already be set at the very beginning of MainParseArgs or even when initializing the global variable itself, without any observable difference. Not even the ::= variable modifier could do anything about this since it is not reachable from the dashed command line options as well, and in addition, it expands its right-hand side in any case, always discarding undefined variables. Oh, these little inconsistencies everywhere.

make(1): treat malformed :range, :ts and :[...] as errors Before, integer overflow in the :[1..2] modifier had not been detected, and the actual behavior varied between ILP64 and LP64I32 machines. Before, the :ts modifier accepted character literals like \012345 and \x1F600, which don't fit in a single character and were thus truncated. Before, the :range modifier issued an "Unknown modifier" error message for :range=x, which was not quite correct. The error message in this case is now "Invalid number".

make(1): make parsing of the :gmtime and :localtime modifiers stricter These variable modifiers accept an optional timestamp in seconds, to select which date to print. This feature is only used very rarely. The NetBSD build doesn't use it at all, and the FreeBSD build mainly uses the plain modifiers :gmtime and :localtime, but not their optional argument :gmtime=1500000000. Therefore, this change is not going to affect many builds. Those that are indeed affected had been wrong all the time anyway. At parse time, these errors stop the build, as intended. After that, when the actual shell commands of the targets are expanded and run, these errors don't stop anything, the build just continues as if nothing had happened. This is a general problem with Var_Parse, see the many "handle errors" markers in the code. Another problem is that on parse errors, parsing continues and spits out spurious strings of the form "mtime" and "ocaltime". This as well is a general problem with error handling in make. ok sjg

make(1): do not look up local variables like .TARGET anywhere else Nobody defines a global variable named .TARGET since that would have many unpredictable effects, applying to all targets at once. Nobody defines an environment variable named .TARGET since that's against the naming conventions for environment variables and would have the same effect. Because of this, there is no point looking up the variables that are local to a GNode anywhere else. This means they cannot come from the environment and thus their value doesn't need to be freed after use, which makes the code simpler. The newly added accessor functions in make.h refer to external functions, but since that header is not used anywhere outside of usr.bin/make, it doesn't matter. Between 2020-08-25 and 2020-10-30, that header had been referenced by usr.bin/xinstall.

make(1): group the command line options and arguments By having a single struct that holds all command line options and arguments, it is easy to see in the code when such a command line argument is modified. It also cleans up the namespace since the command line options don't follow a common naming style. Having them in a struct also means that there is a single place for putting the documentation, not two as before. The struct also suggests to extract the initialization code out of main, which is still too large, having more than 400 lines of code and covering far too many topics.

make(1): sort variables in debug output This way it's easier to see whether an expected variable is missing, or to compare the values of related variables, since they usually share a common prefix. Any sorting criterion is better than the hash code. Sorting the variables by name changed the order of the output in varname.mk. That test didn't test anything meaningful, it was just a playground to understand and demonstrate the current implementation of how the variables are stored, therefore it has been removed.

make(1): rework memory allocation for the name of variables There's more to know about variable names than fits in a one-liner. While here, enforce that the name is not modified by splitting it into the established (var + var_freeIt) pattern. Since the name is not modified and not freed in the middle of evaluating an expression, there is no need to make a backup copy of it. That code had been necessary more than 12 years ago, but not anymore since the code got a lot cleaner since then.

make(1): fix double-free bug in -DCLEANUP mode (since 2020-10-02) The bug had been introduced with dir.c 1.155 on 2020-10-02 22:20:25. In that commit, openDirectories was replaced with a combination of a list with a hash table, for more efficient lookup by name. Upon cleanup, OpenDirs_Done is called, which in turn called Dir_ClearPath. Dir_ClearPath takes full ownership of the given list and empties it. This was no problem before since afterwards the list was empty and calling Lst_Free just frees the remaining list pointer. With OpenDirs, this list was combined with a hash table, and the hash table contains the list nodes, assuming that the OpenDirs functions have full ownership of both the list and the hash table. This assumption was generally correct, except for the one moment during cleanup where full ownership of the list was passed to Dir_ClearPath, while the hash table still contained pointers to the (now freed) list nodes. This by itself was not a problem since the hash table would be freed afterwards. But as part of Dir_ClearPath, OpenDirs_Remove was called, which looked up the freed directory by name and now found the freed list node, trying to free it again. Boom. Fixed by replacing the call to Dir_ClearPath with code that only frees the directories, without giving up control over the list.

make(1): ignore -env and -literal in assignments to .MAKE.EXPORTED Previously, assigning the string "-env" to the variable .MAKE.EXPORTED had the same effect as the .export-env directive. This was only due to a sloppy implementation, not by design. For the string "-literal" and the directive .export-literal, the situation was even worse since the actually executed code was a wild mixture between .export and .export-literal that in the end exported the expanded form of the variable. Therefore there was no practical use case of this implementation flaw.

Therefore don't export these. This also affects a few edge cases that don't occur in practice, such as setting .MAKE.EXPORTED=-env or .MAKE.EXPORTED=-literal. These had not worked as expected anyway.

make(1): fix bug in evaluation of indirect variable modifiers
Since 2020-09-22, when indirect variable modifiers were applied to a
variable expression based on an undefined variable, these modifiers did
not change the state of a variable expression from undefined to defined.
The modifiers that do this are :D, :U, :L, :P. Minimal example:
${VARNAME:${:UL}}
The :L modifier from the inner expression sets the value of the outer
expression to its variable name, in this case "VARNAME". The outer
expression was not marked as being defined though, which resulted in a
"Malformed conditional" error.
In the commit from 2020-09-22, vardebug.exp had changed a lot, and I had
not inspected the change closely. The important detail was in lines 56
and 60, where VAR_JUNK|VAR_KEEP changed into VEF_UNDEF, thereby losing
the VEF_DEF bit.

Splitting the function into 3 separate functions avoids this confusion. It also reveals several places where the complicated API led to unreachable code. Such code has been removed.

make(1): inline character constants in var.c
This removes a level of indirection, and the macro names were quite
similar in appearance as well. The macros may have been used by people
whose editors don't recognize C string and character literals when
navigating to the corresponding brace or parenthesis. These editors had
already been confused before this commit since there are also string
literals with unbalanced parentheses, and there are far fewer
compensating comments such as /*{*/ or /*)*/ in the code. In fact, the
only such comment that is left over was in for.c.
This way, there is now a single consistent way of writing these

make(1): don't require nested variables to be defined in conditions This code only applies to lint mode (-dL) for now. After a test phase and a thorough check for possible side effects, it will be activated in normal mode, too. Having this code in lint mode is required to run src/build.sh, which relies a lot on using variables with undefined nested variables in conditions. In the default mode, any errors about nested undefined variables are not printed since in Var_Subst, oldVars is true. Therefore, it is not urgent to properly handle these nested variables correctly there.

make(1): prepare Var_Parse for proper error handling and reporting Right now, Var_Parse swallows many errors during parsing and evaluation. Ideally, these errors should propagate from the deeply nested expressions where they occur up to the top-level expressions. When such an error occurs, the depending expressions should not be evaluated any further. They may still be parsed, but side effects should be minimized. The goal is to prevent incomplete expressions like the "xy}" in moderrs.exp:106 from being evaluated and eventually passed to the shell for execution. This expression is a left-over from a parse error in the mod-t-parse target in moderrs.mk:154. This commit is a first step in analyzing and verifying the current state of affairs. The modelling in VarParseErrors already looks complicated but is expected to closely match reality.

make(1): clean up RCSID blocks These blocks mostly consisted of redundant structure, following the same #ifndef pattern over and over, with only minimal variation. It's easier to maintain if the common structure is only written once and encapsulated in a macro. To avoid "defined but unused" warnings from GCC in the case where MAKE_NATIVE is not defined, I had to add volatile. Adding MAKE_ATTR_UNUSED alone would not preserve the rcsid variable in the resulting binary.

make(1): inline call to strchr in ValidShortVarname It's a pity that neither GCC 5 nor GCC 10 nor Clang 9 inline this code themselves, even though it would be easy to do. Clang 9 at least replaces strchr with memchr, but that is still too complicated for a simple "is this character one of these" question. For a repeated "if (varname != ...)" instead of the switch, GCC 10 generates really boring and inefficient code, even though it is easy to see that the order of the comparisons doesn't matter.

make(1): in lint mode, complain about erroneous $$ Since 2008-12-21, make has silently ignored strange variable names in constructs like '$$', '$}', '$' followed by nothing. Ignoring these bugs in makefiles instead of reporting them is not a good idea. To improve the situation, make complains about these errors now, but only in lint mode (-dL). This preserves existing behavior while still allowing to validate existing makefiles that they don't depend on this bug. If the test phase goes well, these error messages may be enabled unconditionally. https://mail-index.netbsd.org/pkgsrc-users/2020/09/12/msg032229.html

Since these "- 1" lines lead to slow execution, each branch now increments the pointer separately by the actually needed amount. Fixing this bug posed way more new questions than it answered, and it revealed an inconsistency in the parser about how characters are to be escaped, and missing details in the documentation of Var_Parse, as well as a parse error that unexpectedly doesn't stop make from continuing.

make(1): distinguish enum flags and values in debugging mode When printing an enum value in debugging mode, distinguish between bitsets containing flags and ordinary enums that just contain different values. Make the macros in enum.h more uniform. Provide a simple scheme for defining the run-time type information of enums whose number of values is a number with more than 2 bits set in the binary representation. This case was not obvious before, and it was pure luck that the current interesting enum types only had 3, 10 or 32 different values. The type with the 32 different values actually only has 31 significant bits since the enum constant OP_OPMASK is only used when querying the enum, not for defining or describing the possible values. For this reason, it was unavoidable to refactor the rtti macros, to support even this case.

make(1): in debug mode, print GNode details in symbols A string like OP_DEPENDS|OP_OPTIONAL|OP_PRECIOUS is much easier to read and understand than the bit pattern 00000089. The implementation in enum.h looks really bloated and ugly, but using this API is as simple and natural as possible. That's the trade-off. In enum.h, I thought about choosing the numbers in the macros such that it is always possible to combine two of them in order to reach an arbitrary number, because of the "part1, part2" in the ENUM__SPEC macro. The powers of 2 are not these numbers, as 7 cannot be expressed as the sum of two of them. Neither are the fibonacci numbers since 12 cannot be expressed as the sum of 2 fibonacci numbers. I tried to find a general pattern to generate these minimal 2-sum numbers, but failed.

make(1): remove unreached code from bmake_strndup The "at most" branch was never taken since all call sites in var.c only ever need a substring, and the target buffer is not limited. Therefore rename the function and make it simpler. It's ok that bmake_strldup is defined as estrndup in case of USE_EMALLOC since that function's implementation is compatible to the "copy exactly", it just contains some extra null checks that will never match since the variable values cannot (well, or should not) contain null bytes. Theoretically they can, but the behavior then depends on the exact implementation and is unreliable, therefore nobody does this. After all, Makefiles are used for text processing, not for binary data.

make(1): prepare var.c for WARNS=6 I'm unhappy with the (unsigned) casts for the enum constants, but there is no way around that since the base type of enums is int by definition, and there is no way in C90 to explicitly specify the base type of an enum type. The (size_t) casts on the pointer differences are another pain point, but for these as well, C90 does not have a ready-made solution. A possible workaround would be an inline function ptr_diff that returns size_t instead of ptrdiff_t, but that would make the code look even more bloated than with the casts. The remaining casts to (char), (int) and (time_t) look so suspicious that it's easy enough to stumble upon them, as soon as someone finds the time to fix these properly by adding a function ParseInt or ParseSeconds.

make(1): revert C99 initializer in ApplyModifiers The code of usr.bin/make is supposed to be C90-compatible. That's why it neither uses line-end comments nor declaration-after-statement nor a few other features. The fields that were copied "by name" did not get any additional comments, only the ones with literal values did, since it's hard to see what these mean. This style of initializer has the additional benefit that a missing or extraneous initializer-item would lead to a compile-time error, rather than going undetected.

make(1): add more detailed debug logging for variable modifiers Before a modifier is applied to a variable, it is not yet parsed, therefore it is only possible to log a rough estimate of the modifier. But after applying it, the parsing position has advanced, and the full modifier can be logged. In addition, to fully understand how the modifiers work, it's not enough to just know the variable names and values, there are also some flags that influence how the modifiers behave. The most influential is VARE_WANTRES. Thanks to sjg for the extensive review and valuable feedback on the first drafts.

make(1): improve error message in case of unfinished modifiers
The previous error message "Unclosed substitution" was wrong for several
reasons.
It is not about "unclosed", but about "unfinished" since in the
:@var@...@ modifier the missing '@' does not really close anything.
The word "substitution" may have originated in a time where :S and
:from=to were the only modifiers, and these were indeed substitutions,
but several other modifiers aren't.
The :S and :C modifiers allow an arbitrary delimiter, therefore it is
helpful to enclose the delimiter in quotes, just in case someone chooses
')' or '{' or even ' ' as delimiter.

make(1): switch Buffer size from int to size_t This change helps to make the various integer types compatible and is a preparational step for setting WARNS=6 in the Makefile. The documentation of buf.c has been cleaned up and condensed since it was mostly redundant, and some statements were even slightly wrong. All code changes are covered by the existing unit tests, except for the few lines in for.c around for_var_len. These changes have been reviewed thoroughly and manually, like all the others in this commit. Those buffer functions that deal with sizes have been renamed by appending a Z, to make sure that no function call was accidentally forgotten. They will be renamed back in a follow-up commit. As usual, the scope of a few affected variables has been reduced, and some variables had to be split since they had been incorrectly merged before. The order of the arguments to Buf_AddBytes has changed from (mem_len, mem) to (mem, mem_len), in order to make it consistent with the functions from the C standard library, such as snprintf.

make(1): fix segfault when evaluating ${::=value}
The bug had been in the handling of the SysV modifier for many years, but
it had not been triggered since the "parsing position for the next
modifier" had been initialized to a non-NULL pointer.
In var.v r1.350, this pointer had been initialized to NULL instead since
every ApplyModifier function must set it in every case where it returns
anything except "default_case".
There might have been a slight chance of tricking make to output a wrong
error message, but nothing worse.

make(1): remove dead code from Var_Subst
The first parameter from Var_Subst had been a literal NULL in all cases.
These have been fixed using this command:
sed -i 's|Var_Subst(NULL, |Var_Subst(|' *.c
The one remaining case was not found because the "NULL," was followed by
a line break instead of a space.
The removed code probably wouldn't have worked as expected anyway.
Expanding a single variable to a literal string would have led to
unexpected behavior for cases like ${VAR:M${pattern}}, in case pattern
would contain an unescaped ':' itself.

make(1): remove unnecessary variable assignment It is not the job of an ApplyModifier function to directly manipulate the final result of the ApplyModifiers function. In fact, the resulting pointer was overwritten unconditionally, in such an obvious way that the compiler could have detected this. GCC 5 didn't though, which reduces the code size a bit.

make(1): make modifier handling simpler Implementing a modifier such as :S or :M should not be concerned with separating the words of the resulting string. Ideally this should be done in the same way by all modifiers. Before, the :R (filename root) modifier added a separator even if the resulting filename root was an empty string. The chances that this change in behavior breaks anything are epsilon. The :@ modifier, if it appeared after a :ts modifier, did not use the word separator from the :ts modifier (which all other modifiers do) but always added a space. This behavior has been preserved for now. It's an unnecessary inconsistency though. In contrast to Buffer, the newly added SepBuf uses size_t for memory sizes and also uses the conventional parameter order (mem, memsize) instead of the unusual (memsize, mem).

make(1): make ampersand in ${VAR:from=to&} an ordinary character
In SysV substitutions, wildcards are expressed with % instead of &. The
& is not mentioned in the manual page, and having another wildcard for
the whole word would be such an obscure feature that not even pkgsrc uses
it. The easiest way to discover this feature had been to read the source
code of make(1) or to use a fuzzer and accidentally stumble upon this
edge case.

Fix parsing of nested variables during .for loop
Recent change to cond.c to avoid eval of unnecessary
terms had side effect on constructs like:
.for s in 1 2
.if defined(MAN$s) && !empty(MAN$s)
MAN+= ${MAN$s}
.endif
.endfor
resulting in MAN being flagged as recursive.
When Var_Parse encounters a variable within a variable name
we want to force it to be expanded.
But given the way get_mpt_arg calls Var_Parse we need to check
whether we actually started parsing a variable yet.

When evaluating condtionals from .if we want to require that the lhs is a variable reference, a number or a quoted string. This helps avoid subtle bugs caused by typos. When conditionals are being evaluated during variable expansion we cannot be as strict becuase lhs will already have been expanded. We therefor pass a boolean to Cond_EvalExpression to tell it how lhs should be treated. Add unit-tests/cond2.mk to test the above Reviewed by: christos, joerg
