-Subject: [PATCH] DEV: hpack: fix `trash` build regression
-
-Since 7d84439 ("BUILD: hpack: include global.h for the trash that is needed
-in debug mode"), hpack decode tool fails to compile on targets that enable
-USE_THREAD. (ie: linux-glibc target as reported by Christian Ruppert)
-
-When building hpack devtool, we are including src/hpack-dec.c as a dependency.
-src/hpack-dec.c relies on the global trash whe debug mode is enabled.
-But as we're building hpack tool with a limited scope of haproxy
-sources, global trash (which is declared in src/chunk.c) is not available.
-Thus, src/hpack-dec.c relies on a local 'trash' variable declared within
-dev/hpack/decode.c
-
-This used to work fine until 7d84439.
-But now that global.h is explicitely included in src/hpack-dec.c,
-trash variable definition from decode.c conflicts with the one from global.h:
-
-  In file included from include/../src/hpack-dec.c:35,
-                   from dev/hpack/decode.c:87:
-  include/haproxy/global.h:52:35: error: thread-local declaration of 'trash' follows non-thread-local declaration
-     52 | extern THREAD_LOCAL struct buffer trash;
-
-Adding THREAD_LOCAL attribute to 'decode.c' local trash variable definition
-makes the compiler happy again.
-
-This should fix GH issue #2009
