------------------------------------------------------------ revno: 12695 revision-id: squid3@treenet.co.nz-20160420064259-k9dn77q0xna1doax parent: squid3@treenet.co.nz-20160330141606-19rqzzip0grq9a77 committer: Amos Jeffries <squid3@treenet.co.nz> branch nick: 3.3 timestamp: Wed 2016-04-20 18:42:59 +1200 message: cachemgr.cgi: use dynamic MemBuf for internal content generation Using a fixed size buffer limits how big content lines can be. Modern HTTP is fast reaching the point where such limits are problematic. Also fixes incorrect uses of snprintf() by removing them. ------------------------------------------------------------ # Bazaar merge directive format 2 (Bazaar 0.90) # revision_id: squid3@treenet.co.nz-20160420064259-k9dn77q0xna1doax # target_branch: http://bzr.squid-cache.org/bzr/squid3/3.3 # testament_sha1: 0c7cd2d0ababe794c0fd5b1dc94c647c064c122d # timestamp: 2016-04-20 06:50:48 +0000 # source_branch: http://bzr.squid-cache.org/bzr/squid3/3.3 # base_revision_id: squid3@treenet.co.nz-20160330141606-\ # 19rqzzip0grq9a77 # # Begin patch === modified file 'src/tests/Stub.list' --- src/tests/Stub.list 2014-10-08 15:31:39 +0000 +++ src/tests/Stub.list 2016-04-20 06:42:59 +0000 @@ -3,6 +3,7 @@ tests/stub_acl.cc \ tests/stub_cache_cf.cc \ tests/stub_cache_manager.cc \ + tests/stub_cbdata.cc \ tests/stub_client_db.cc \ tests/stub_client_side_request.cc \ tests/stub_comm.cc \ === added file 'src/tests/stub_cbdata.cc' --- src/tests/stub_cbdata.cc 1970-01-01 00:00:00 +0000 +++ src/tests/stub_cbdata.cc 2016-04-20 06:42:59 +0000 @@ -0,0 +1,30 @@ +#include "squid.h" +#include "cbdata.h" + +#define STUB_API "cbdata.cc" +#include "tests/STUB.h" + +void cbdataRegisterWithCacheManager(void) STUB +void *cbdataInternalAlloc(cbdata_type type, const char *, int sz) { + return xcalloc(1, sz); +} +void *cbdataInternalFree(void *p, const char *, int) { + xfree(p); + return nullptr; +} +#if USE_CBDATA_DEBUG +void *cbdataInternalAllocDbg(cbdata_type type, const char *, int) STUB_RETVAL(NULL) +void *cbdataInternalFreeDbg(void *p, const char *, int) STUB_RETVAL(NULL) +void cbdataInternalLockDbg(const void *p, const char *, int) STUB +void cbdataInternalUnlockDbg(const void *p, const char *, int) STUB +int cbdataInternalReferenceDoneValidDbg(void **p, void **tp, const char *, int) STUB_RETVAL(0) +#else +void *cbdataInternalAlloc(cbdata_type type) STUB_RETVAL(NULL) +void *cbdataInternalFree(void *p) STUB_RETVAL(NULL) +void cbdataInternalLock(const void *p) STUB +void cbdataInternalUnlock(const void *p) STUB +int cbdataInternalReferenceDoneValid(void **p, void **tp) STUB_RETVAL(0) +#endif + +int cbdataReferenceValid(const void *p) STUB_RETVAL(0) +cbdata_type cbdataInternalAddType(cbdata_type type, const char *label, int size, FREE * free_func) STUB_RETVAL(CBDATA_UNKNOWN) === modified file 'src/tests/stub_mem.cc' --- src/tests/stub_mem.cc 2012-08-29 07:29:35 +0000 +++ src/tests/stub_mem.cc 2016-04-20 06:42:59 +0000 @@ -5,7 +5,7 @@ #include "squid.h" #define STUB_API "stub_mem.cc" -#include "STUB.h" +#include "tests/STUB.h" #include "Mem.h" void === modified file 'tools/Makefile.am' --- tools/Makefile.am 2010-12-06 14:06:06 +0000 +++ tools/Makefile.am 2016-04-20 06:42:59 +0000 @@ -34,15 +34,24 @@ stub_debug.cc: $(top_srcdir)/src/tests/stub_debug.cc cp $(top_srcdir)/src/tests/stub_debug.cc . +MemBuf.cc: $(top_srcdir)/src/MemBuf.cc + cp $(top_srcdir)/src/MemBuf.cc $@ + time.cc: $(top_srcdir)/src/time.cc cp $(top_srcdir)/src/time.cc . +stub_cbdata.cc: $(top_srcdir)/src/tests/stub_cbdata.cc + cp $(top_srcdir)/src/tests/stub_cbdata.cc $@ + +stub_mem.cc: $(top_srcdir)/src/tests/stub_mem.cc + cp $(top_srcdir)/src/tests/stub_mem.cc $@ + # stock tools for unit tests - library independent versions of dlink_list # etc. # globals.cc is needed by test_tools.cc. # Neither of these should be disted from here.
