This fixes t5516 on Windows. For detailed explanation please refer to code comments in this commit. There was a lot of back-and-forth already in vreportf(): d048a96e (2007-11-09) - 'char msg[256]' is introduced to avoid interleaving 389d1767 (2009-03-25) - Buffer size increased to 1024 to avoid truncation 625a860c (2009-11-22) - Buffer size increased to 4096 to avoid truncation f4c3edc0 (2015-08-11) - Buffer removed to avoid truncation b5a9e435 (2017-01-11) - Reverts f4c3edc0 to be able to replace control chars before sending to stderr This fix attempts to solve all issues: 1) avoid multiple fprintf() interleaving 2) avoid truncation 3) avoid char interleaving in fprintf() on some platforms 4) avoid buffer block interleaving when output is large 5) avoid Out-of-order messages 6) replace control characters in output Other commits worthy of notice: 9ac13ec9 (2006-10-11) - Another attempt to solve interleaving. This is seemingly related to d048a96e. 137a0d0e (2007-11-19) - Addresses out-of-order for display() 34df8aba (2009-03-10) - Switches xwrite() to fprintf() in recv_sideband() to support UTF-8 emulation eac14f89 (2012-01-14) - Removes the need for fprintf() for UTF-8 emulation, so it's safe to use xwrite() again 5e5be9e2 (2016-06-28) - recv_sideband() uses xwrite() again Signed-off-by: Alexandr Miloslavskiy alexandr.miloslavskiy@xxxxxxxxxxx [alexandr.miloslavskiy@xxxxxxxxxxx] Alexandr Miloslavskiy (1): vreportf: Fix interleaving issues, remove 4096 limitation usage.c | 154 +++++++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 148 insertions(+), 6 deletions(-) base-commit: d966095db01190a2196e31195ea6fa0c722aa732 Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-407%2FSyntevoAlex%2F%230194_t5516_fixes-v1 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-407/SyntevoAlex/#0194_t5516_fixes-v1 Pull-Request: https://github.com/gitgitgadget/git/pull/407 -- gitgitgadget
