This commit improves the parser and compiler error messages, making
it more easier to understand where in the filter the problem is.
Like modern compilers, jq will show the line in the filter where the
error occurred, will display squiggly line under the invalid token.
This commit drops support for parsing NaN with payload in JSON like
`NaN123` and fixes CVE-2024-53427. Other JSON extensions like `NaN` and
`Infinity` are still supported. Fixes#3023, fixes#3196, fixes#3246.
Whether `char` has a sign is implementation dependent, and `c >= 0` may
result in a compiler warning. We can use bitwise operator to check
whether the character is a control character, regardless of the sign.
The `jv2tm` function was zeroing fields of `struct tm` that were not
specified by the standard. However, depending on the libc this produced
incorrect timezone data when used together with formatting functions.
This change tries to fill the timezone data using either `mktime`,
`timegm`, or manually.
Apple's Libc implementation contains a bug which causes it to ignore
the offset data present in the `struct tm` in favor of the older heuristic
needed by legacy standards. This workaround temporarily sets the global
timezone so it gets picked up during formatting.
* Improve reliability of NO_COLOR tests.
Use `env` to ensure that `NO_COLOR` is set to the desired value
regardless of any initialization that may occur when `script`
forks a shell to run jq in.
Note that `env -u` is not portable, so there is no good solution
for the first test case.
* Always use /bin/sh, not the user's login shell.
Fixes:
* Short options cannot be repeated in the same group:
e.g., `-nn` fails, but `--null-input --null-input` works
* Short options are processed in an arbitrary fixed order, not the order
given by the user: e.g., `-hV`, `-Vh`, `-h -V`, and `--help --version`
are processed as `-h`, but `-V -h` and `--version --help` are
processed as `-V`
* `-L` cannot be a part of a short option group (as the last one):
e.g., `-nLlib` and `-nL lib` fail
decNumberToString calls for a buffer that can hold a string of digits+14
characters, not a buffer of size digits+14.
We need to allocate an extra byte for the NUL byte.
-10E-1000010001, for example, will be stringified as -1.0E-1000010000
and decNumberToString will currently write an extra NUL byte after the
allocated buffer in the heap.

The unit allocated for decNumberCompare was accidentally removed by
commit 680baeffeb (PR #2804)
This caused a stack overflow when comparing a nan with a payload of 1000
or more.

This commit temporarily reverts the commit that allows #\ "tcl-style"
comments everywhere and documents them, for the 1.7.1 patch release
cca1f7d18f.
\r is removed from the list of characters not allowed in a comment to
preserve that bugfix.
Replace deprecated test(1) parentheses and -a logical operator with two
tests command.
Replace deprecated tail -1 with tail -n1.
Replace non-standard egrep(1) command with grep -E ; this also
prevents obsolescence warnings on GNU systems.
The locale test was using ./jq intead of $JQ.
I also removed the use of obsolete egrep instead of grep -E that
triggers warnings on GNU systems, and the use of deprecated head -1
instead of head -n1.
Also removed the unnecessary hiding of strptime/1 errors with
? // false.
* bugfix: comments were incorrectly being terminated by CR; for example
jq -n $'1 #foo\r'
fails to compile because the CR character terminates the comment, and
CR is not a valid character in jq syntax.
* improvement: comments fully support Tcl-style line continuation.
Previously this was only "supported" in `-f' scripts, whose first line
starts with "#!", and second line starts with # and ends with \, only
for the comment on the second line, only for one extra line.
* man: document comment syntax, which was previously undocumented.
* tests: add regression tests for the bugfix, and some tests for line
continuation in comments.
This reverts commit 0e70f7a57e.
There is no reason to revert this change.
In #2922, I only disagreed with the commit message suggesting that
LC_CTYPE=C od -t c is equivalent to od -c
The only documented differences are that -tc is required to be
influenced by -N and -j, while -c is not, and that -c is required to
only support a subset of the backslash sequences that -tc should
support.
jq previously only allowed passing the inline script before -- (as if
they were options) even though one would expect the inline script to be
a positional argument.
Since jq previously also refused to run with a usage error if the script
was passed after -- (It was not assuming . as script as it does when
no arguments are passed), and positional arguments are allowed before --
and even before other options, it should not be a breaking change to
change that weird behaviour, and allow the script to appear after --.
It also simplifies the option parsing code a bunch.
Fixes#2918
* Build windows 64bit binary using UCRT64
Is the default and recommended msystem setting. Will produce
binaries that are compatible with windows 10 and later.
Also run tests for 32bit build.
Related to #2831
* Use jq -b in tests/shtest
* Add Windows strptime
* Make Windows-optional tests not run on Windows again

Previously constant folding of zero division (e.x. 1/0) produces a
compile error. This was incorrectly implemented by checking if the
division result is infinite, so produces wrong results compared to the
query where no constant folding is processed (e.x. 1e308/0.1). This
patch delays the operation when the divisor is zero. This makes the
results more consistent, but changes the exit code on zero division from
3 to 5. Also 0/0 now produces the zero division error, not NaN.
This patch also fixes the modulo operation. Previously constant folding
logic does not take care of the % operator, but now it folds if the both
dividend and divisor are safe numbers to cast to the integer type, and
the divisor is not zero. This patch also fixes some code that relies on
undefined cast behaviors in C. The modulo operation produces NaN if
either the dividend or divisor is NaN.
The option naming --nul-output was confusing, especially when we have a
similar option for input stream in the future (--nul-input vs --null-input).
Based on the observation of other command line tools, we rename the option
to --raw-output0. We also drop the short option -0 to avoid confusion on
introducing the NUL-delimited input option.
Unlike the other command line tools outputting file names with NUL delimiter,
jq deals with JSON, and its strings may contain NUL character. To protect
users from the risk of injection attacks, we abort the program and print an
error message before outputting strings including NUL character. Closes#2683.
