This variant will be more interoperable across various systems
and it's already used in Ruby module.
Otherwise, configure tests fail on NetBSD with:
gcc: Missing argument for -Wl,-rpath
Now it's possible to disable default bind mounts of
languages by setting:
{
"isolation": {
"automount": {
"language_deps": false
}
}
}
In this case, the user is responsible to provide a "rootfs"
containing the language libraries and required files for
the application.
An attempt to build a Ruby module for a custom Ruby installation that has the
same major version as the system Ruby may unexpectedly cause the use of the
system Ruby library.
This closes#449 issue on GitHub.
Since the introduction of rootfs feature, some language modules
can't be configured multiple times.
Now the configure generates a separate nxt_<module>_mounts.h for
each module compiled.
Some PPAs for Ubuntu package PHP with versions like:
7.2.28-3+ubuntu18.04.1+deb.sury.org+1
But the script expected only "X.Y.Z".
The issue was introduced in:
http://hg.nginx.org/unit/rev/2ecb15904ba5
For each request, the worker calls the php_execute_script function
from libphp that changes to the script directory before doing its
work and then restores the process directory before returning. The
chdir(2) calls it performs are unnecessary in Unit design. In simple
benchmarks, profiling shows that the chdir syscall code path (syscall,
FS walk, etc.) is where the CPU spends most of its time.
PHP SAPI semantics requires the script to be run from the script
directory. In Unit's PHP implementation, we have two use cases:
- script
- arbitrary path
The "script" configuration doesn't have much need for a working
directory change: it can be changed once at module initialization.
The module needs to chdir again only if the user's PHP script also
calls chdir to switch to another directory during execution.
If "script" is not used in Unit configuration, we must ensure the
script is run from its directory (thus calling chdir before exec),
but there's no need to restore the working directory later.
Our implementation disables mandatory chdir calls with the SAPI
option SAPI_OPTION_NO_CHDIR, instead calling chdir only when needed.
To detect the user's calls to chdir, a simple "unit" extension is
added that hooks the built-in chdir() PHP call.
Temporary file name with configure process PID used to download
JAR from external repository. Then file renamed using command 'mv'.
The issue reproduced in clean environment when 2 or more concurrent builds
started.
Python 3.8 has 'tp_print' field in PyTypeObject struct. This field is
attributed as deprecated. So, clang generates warning (which is turned to
error) as a result of initializing this field. From the other hand, it is
impossible to omit this field in positional initialization. The solution
is to use designated initializer.
Silencing usage message during configure python.
This is related to #331 issue on GitHub.
Currently almost all Unit object files depends on generated nxt_version.h.
This patch adds missing dependence and fixes running make with multiple
jobs.
This closes#318 issue on GitHub.
Some Perl compile options affects ABI and not using them while compiling
our module resulted in non-working build.
Notably on 32-bit Debian 10, Perl is built with -D_FILE_OFFSET_BITS=64
and our module after being compiled without this option caused segmentation
faults in unexpected places.
It's surplus option because the perl executable returns the proper path.
Also the Perl module configure script was cleaned up a bit.
Note that NXT_PERL_LDOPTS already contains the library path.
While it looks nicer without zero 3-rd version number, this should
improve interoperability. Version string can be parsed or used for
sorting. And it is easier to handle and less confusing when there
is constant number of version parts.
Moreover, NPM also expects version format with 3 parts.
So ".0" has already been used in Node.js module version.
By default "npm install" switches to non-privileged user to run package scripts
if it is invoked by root. As a result it may prevent node-gyp from writing to
package directory and break installation of the module.
To disable this switching the --unsafe-perm flag is added.
In most cases it is not needed because Ruby libraries are in the default path.
At the same time, rpath pointing to the default path is prohibited by rpmbuild
on Fedora.
This is related to issue #87 on GitHub.
Since PHP 7, a zend_signal_startup() call is required if the interpreter
was built with ZEND_SIGNALS defined; such a call was added in 3fd76e4ce70a.
However, the zend_signal_startup() export is missing from the PHP library;
as the result, dlopen() fails with the 'Undefined symbol "zend_signal_startup"'
error while loading the PHP module.
Meanwhile, if PHP is built without ZTS, the zend_signal_startup() call can
be omitted; otherwise, the missing call causes segmentation fault.
The PHP fix already was committed to upstream, but we still have to deal
with numerous unpatched versions remaining at large.
