| 2019年11月02日 | add time64 redirect for, and redirecting implementation of, dlsym | Rich Felker | -0/+4 |
|
if symbols are being redirected to provide the new time64 ABI, dlsym
must perform matching redirections; otherwise, it would poke a hole in
the magic and return pointers to functions that are not safe to call
from a caller using time64 types.
rather than duplicating a table of redirections, use the time64
symbols present in libc's symbol table to derive the decision for
whether a particular symbol needs to be redirected.

| 2014年01月06日 | const-qualify the address argument to dladdr | Rich Felker | -1/+1 |
|
this agrees with implementation practice on glibc and BSD systems, and
is the const-correct way to do things; it eliminates warnings from
passing pointers to const. the prototype without const came from
seemingly erroneous man pages.

|
| 2013年01月23日 | add RTLD_NODELETE flag for dlopen | Rich Felker | -0/+1 |
|
this is a trivial no-op, because dlclose never deletes libraries. thus
we might as well have it in the header in case some application wants
it, since we're already providing it anyway.

| 2013年01月23日 | add support for RTLD_NOLOAD to dlopen | Rich Felker | -0/+1 |
|
based on patch by Pierre Carrier <pierre@gcarrier.fr> that just added
the flag constant, but with minimal additional code so that it
actually works as documented. this is a nonstandard option but some
major software (reportedly, Firefox) uses it and it was easy to add
anyway.

| 2012年09月07日 | default features: make musl usable without feature test macros | Rich Felker | -5/+1 |
|
the old behavior of exposing nothing except plain ISO C can be
obtained by defining __STRICT_ANSI__ or using a compiler option (such
as -std=c99) that predefines it. the new default featureset is POSIX
with XSI plus _BSD_SOURCE. any explicit feature test macros will
inhibit the default.
installation docs have also been updated to reflect this change.

| 2012年09月06日 | dladdr should be available under _BSD_SOURCE as well as _GNU_SOURCE | Rich Felker | -1/+1 |
|
| 2012年09月06日 | use restrict everywhere it's required by c99 and/or posix 2008 | Rich Felker | -1/+7 |
|
to deal with the fact that the public headers may be used with pre-c99
compilers, __restrict is used in place of restrict, and defined
appropriately for any supported compiler. we also avoid the form
[restrict] since older versions of gcc rejected it due to a bug in the
original c99 standard, and instead use the form *restrict.

| 2012年08月26日 | dladdr support for dynamic linker (nonstandard extension) | Rich Felker | -0/+10 |
|
based on patches submitted by boris brezillon. this commit also fixes
the issue whereby the main application and libc don't have the address
ranges of their mappings stored, which was theoretically a problem for
RTLD_NEXT support in dlsym; it didn't actually matter because libc
never calls dlsym, and it seemed to be doing the right thing (by
chance) for symbols in the main program as well.
