|
||||
If libpcre2-posix.so makes it into a process image somehow before
|
||||
libc.so (which is easy: gcc something.c -lpcre2-posix), pcre2's
|
||||
"regcomp" symbol wins a race over libc's "regcomp" symbol. There are
|
||||
likely more situations as well, because libc's "regcomp" is _also_
|
||||
marked as weak. Anyway, because the functions two are not
|
||||
behavior-compatible, problems arise.
|
||||
|
||||
To stay ABI compatible, we could make a new library without regcomp etc.,
|
||||
and edit the .pc file to point to the new library, but that would not
|
||||
capture the case someone uses plain gcc -l without pkg-config.
|
||||
|
||||
Since regcomp is "#defined" to pcre2_regcomp, any programs that were
|
||||
source-compiled are fine. Removing the reg* symbols from the library
|
||||
hence only breaks the case of dlsym(libpcre2-posix, "regcomp"),
|
||||
which, I will argue, is an absolute niche use of the PCRE libraries
|
||||
and something we are willing to break.

- pcre2 10.37:
|

* removal of the actual POSIX names regcomp etc. from the POSIX
|
||||
wrapper library because these have caused issues for some
|
||||
applications, replacing pcre2-symbol-clash.patch
|
||||
* fix a hypothetical NULL dereference
|
||||
* fix two bugs related to over-large numbers so the behaviour is
|

now the same as Perl
|
||||
* Fix propagation of \K back from the full pattern recursion
|
||||
* Restore single character repetition optimization in JIT
