Simplifies the compilation of `foreach` to avoid the problem in #3227 by
removing unnecessary `FORK ... BACKTRACK`.
Does not address `reduce`, which is less trivial.
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.
Using `calloc` function with a count of zero elements is implementation
defined and it may cause allocation errors on some platforms (ref #3277).
This commit fixes `jv_mem_calloc` callers to avoid undefined behavior.
When we use a large format string to `strftime/1` and `strflocaltime/1`,
we get segmentation fault. This happens because the result buffer is
allocated on the stack using `alloca` function, and `strftime` function
writes out of the space when the size is not enough to format time.
I fixed the segmentation fault issue by allocating the result buffer on
the heap using `malloc` function, because `alloca` function does not
provide a way to detect insufficient space.
This commit improves the performance of repeating strings, by copying
the result string instead of the string being repeated. Also it adds
an error message when the result string is too long.
Previously, the configure script automatically enables Valgrind during
testing when the valgrind command is found. However, running tests with
Valgrind is quite slow, so it is better to disable it by default, and
to enable it only when the user specifies the `--enable-valgrind` flag.
On OpenBSD, some prototypes are hidden behind `_BSD_SOURCE`.
Defining this variable fixes#3252, and also fixes#3276.
This can be seen as a regression of #2631.
Previously, `unique` and `unique_by` filters are implemented using
`group_by` and then `map(.[0])`. This commit re-implements in C, to
avoid unnecessary boxing of grouping, and improves the performance.
As discussed in https://github.com/jqlang/jq/discussions/3244, we are
moving jqplay to the jqlang GitHub organization. This updates all
references from jqplay.org to play.jqlang.org.
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.
The code of `jv_number_value` is intended to cache the double value of
literal numbers, but it does not work because it accepts the `jv` struct
by value. This patch fixes the behavior by checking if the double value
is `NaN`, which indicates the unconverted value. This patch improves the
performance of major use cases; e.g. `range(1000000)` runs 25% faster.
We no longer use the `--root` option of `build_website.py` since we have
moved to jqlang.org (from jqlang.github.io/jq where the root was `/jq`).
We don't need the option on local development either since `http.server`
has the `-d` option to specify the directory to serve from.
The -static-libtool-libs flag causes GNU libtool to add a rpath to the .libs
build directory, which is intended for internal use by the libtool
implementation and is not installed in the resulting package causing Gentoo to
print a QA notice. See Gentoo issue: https://bugs.gentoo.org/945698.
* Create `src/config.h` instead of passing everything on the compiler
command line.
* To reduce the magnitude of this change, add `--include src/config.h`
to CFLAGS instead of adding `#include "src/config.h"` at the top of
each source file. Not all compilers support this, but I don't think
we care about anything other than gcc and clang at this point.
* Rather than generate `src/config_opts.inc`, emit `JQ_CONFIG` directly
into `src/config.h`.
* Rather than generate `src/version.h`, define `JQ_VERSION` as an alias
for the standard `PACKAGE_VERSION`.
Adding https://github.com/actions/attest-build-provenance to the ci builds so
that the release assets and docker image for the next release tag generate
signed build provenance attestations for workflow artifacts.
