For performance reasons, it is also recommended to make the (mmap'ed)
shared library 'read-only'.
-> New permissions for installed shared libraries = 555
This doesn't hurt anybody, provided the installation is performed with
'cp -f' :-)
"-Wl,+s" instead of +s:
* Hardcoded necessary references to -ldld/-ldl into the build rules and
removed EX_LIBS.
HP-UX records the pathnames of dependent libraries when the shared libs
are built, so that ./libcrypto.sl... is recorded in libssl.sl..., with
"./" not being resolvable when running an application linked against -lssl:
* Build libssl without explicit reference to libcrypto, applications will
be linked with "-lssl -lcrypto" anyway.
Document these informations in Makefile.org.
full version number and not just 0. This should mark the shared
libraries as not backward compatible. Of course, this should be
changed again when we can guarantee backward binary compatibility.
ld warns that -Fl "may not be supported in future releases". We know
that, and are doing things in HP-UX 11 (64bit), so turn off that
warning with +vnocompatwarnings.
- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.
- Make as few rebuilds of the shared libraries as possible.
- Still avoid linking the OpenSSL programs with the shared libraries.
- When installing, install the shared libraries separately from the
static ones.
1. make sure libssl.so becomes dependent on libcrypto.so
2. correct a number of silly bugs in the solaris-shared target, and make
sure lib*.so also depends on libc.so.
there's support for building under Linux and True64 (using examples
from the programming manuals), including versioning that is currently
the same as OpenSSL versions but should really be a different series.
With this change, it's up to the users to decide if they want shared
libraries as well as the static ones. This decision now has to be
done at configuration time (well, not really, those who know what they
do can still do it the same way as before).
The OpenSSL programs (openssl and the test programs) are currently
always linked statically, but this may change in the future in a
configurable manner. The necessary makefile variables to enable this
are in place.
Also note that I have done absolutely nothing about the Windows target
to get something similar. On the other hand, DLLs are already the
default there, but without versioning, and I've no idea what the
possibilities for such a thing are there...
could be done automagically, much like the numbering in libeay.num and
ssleay.num. The solution works as follows:
- New object identifiers are inserted in objects.txt, following the
syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!). Additions are OK, as well as consistent name changes.
sk_whatever_insert and sk_whatever_set immediately reveals the subtle
difference in parameter order.
Change mkstack.pl so that safestack.h is not rewritten when
nothing has changed.
structures and functions for each stack type. The previous behaviour
can be enabled by configuring with the "-DDEBUG_SAFESTACK" option.
This will also cause "make update" (mkdef.pl in particular) to
update the libeay.num and ssleay.num symbol tables with the number of
extra functions DEBUG_SAFESTACK creates.
The way this change works is to accompany each DECLARE_STACK_OF()
macro with a set of "#define"d versions of the sk_##type##_***
functions that ensures all the existing "type-safe" stack calls are
precompiled into the underlying stack calls. The presence or abscence
of the DEBUG_SAFESTACK symbol controls whether this block of
"#define"s or the DECLARE_STACK_OF() macro is taking effect. The
block of "#define"s is in turn generated and maintained by a perl
script (util/mkstack.pl) that encompasses the block with delimiting
C comments. This works in a similar way to the auto-generated error
codes and, like the other such maintenance utilities, is invoked
by the "make update" target.
A long (but mundane) commit will follow this with the results of
"make update" - this will include all the "#define" blocks for
each DECLARE_STACK_OF() statement, along with stripped down
libeay.num and ssleay.num files.
variety of platforms. A few are missing, and they will be added in
eventually, but as this is new stuff, it was better to not break lots of
platforms in one go that we can't easily test. The changes to "Configure"
should illustrate how to add support to other systems if you feel like
having a go.
NB: I'll add something shortly to allow you to add "dlfcn.h" support on
those platforms that don't have (or need) a dlfcn.h header file. (The
symbol for Configure will probably by "dlfcn_no_h").
Thanks to Richard Levitte, who is responsible for the dso_dl.c support,
understanding the trickier aspects of the build process, and giving great
feedback on everything else.
[Don't use this stuff if you're easily offended by changes to the
interface or behaviour - it's still work in progress.]
