Makefileon commit [PATCH] fetch.c: Make process() look at each object only once (f9cff26)
   1# Define MOZILLA_SHA1 environment variable when running make to make use of
   2# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
   3# on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
   4# choice) has very fast version optimized for i586.
   5#
   6# Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
   7# miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.
   8#
   9# Define NO_CURL if you do not have curl installed.  git-http-pull is not
  10# built, and you cannot use http:// and https:// transports.
  11#
  12# Define NO_STRCASESTR if you don't have strcasestr.
  13#
  14# Define PPC_SHA1 environment variable when running make to make use of
  15# a bundled SHA1 routine optimized for PowerPC.
  16#
  17# Define ARM_SHA1 environment variable when running make to make use of
  18# a bundled SHA1 routine optimized for ARM.
  19#
  20# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  21#
  22# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  23#
  24# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  25# Patrick Mauritz).
  26#
  27# Define NO_GETDOMAINNAME if your library lack it (SunOS, Patrick Mauritz).
  28#
  29# Define WITH_OWN_SUBPROCESS_PY if you want to use with python 2.3.
  30#
  31# Define COLLISION_CHECK below if you believe that SHA1's
  32# 1461501637330902918203684832716283019655932542976 hashes do not give you
  33# sufficient guarantee that no collisions between objects will ever happen.
  34
  35# DEFINES += -DCOLLISION_CHECK
  36
  37# Define USE_NSEC below if you want git to care about sub-second file mtimes
  38# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
  39# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
  40# randomly break unless your underlying filesystem supports those sub-second
  41# times (my ext3 doesn't).
  42
  43# DEFINES += -DUSE_NSEC
  44
  45# Define USE_STDEV below if you want git to care about the underlying device
  46# change being considered an inode change from the update-cache perspective.
