The commit hash you reference is not reachable from the master branch.

Aside of this, some logic arrives from
47c19eeb4f67cb7257ce32542443c09410b6e752 ('build: don't re-export
libcurl.so/dylib symbols').

It is the part of extra/exports, so I would name it
extra/exports_libcurl.

I would also keep Yaroslav's comment at the start:

 | # The following list was obtained by parsing libcurl.a static library:
 | # nm libcurl.a | grep -oP 'T \K(curl_.+)$' | sort
 |
 | curl_easy_cleanup
 | curl_easy_duphandle

I would just pass one or two files (extra/exports,
extra/exports_libcurl) in $1: it'll be easier to read.

(At least it works for libcurl bundling, but I didn't verified it with static
build.)

However explicit listing of public libcurl symbols looks easier to understand
and in tune with master.

Can we just copy test/box-tap/gh-5223-curl-exports.test.lua from
29ec628918bd7279de08e47becc070420775c2eb ('Ensure all curl symbols are

Is it quite straigtforward backport of [1], so it is okay too after the
proposed fixes [2].

Only one note for the backport: it seems, a changelog entry was
forgotten here.

It seems, it is quite straightforward backport of [1], so it is okay
after comments from the original patch ([2]).

Don't miss changelog entries on 1.10.

[1]: https://lists.tarantool.org/pipermail/tarantool-patches/2021-March/022797.html
[2]: https://lists.tarantool.org/pipermail/tarantool-patches/2021-March/023177.html

I performed tests 2 and 3 from [2] and the result looks the same. It
seems, we don't enable or disable something unintentionally here as
well.

WBR, Alexander Turenko.

    build: export libcurl symbols
    
    Export the symbols to tarantool executable in the case of libcurl
    included as bundled library.
    
    This patch is just 1.10 adaptation of the original commit 29ec628

[Tarantool-patches] [PATCH 1/3] build: export libCURL symbols

[Roman Khabibov via Tarantool-patches]

Export the symbols to tarantool executable in the case of libCURL
included as bundled library or static build.

This patch is just 1.10 adaptation of the original commit 9fc57c4
performed by Yaroslav Dynnikov <yaroslav.dynnikov@gmail.com>.
