      htable: avoid branch in calculating perfect bit. · 7623d082
      Rusty Russell authored
      Final results of tools/speed/10000000 (10 runs) shows a slight
      slowdown in some tests, but it makes an empty htable smaller.

      small fix for ccan/take/take.c · 440efa55
      Dmitry Petukhov authored
      Hello.
      
      I've decided to take a look at c-lighting code, because we might
      consider using it in the future.
      
      I found a small problem in ccan/take/take.c that only concerns code
      that runs with CCAN_TAKE_DEBUG set (DEVELOPER=1 for c-lighting).
      
      It is a small issue, but I decided to notify you as the author of the
      code, anyway.
      
      the issue is:
        in take_() function, potential failure of realloc for labelarr is not
        handled.
      
      I attached a diff with a fix.
      
      I thought that making a pull request for c-lighting would not be right,
      as ccan is a separate project, but I did not find a way to report this
      at http://git.ozlabs.org/, where ccan repo resides.
      
      Therefore I wrote to you directly.

      tal/str: always create strings which have tal_count() == strlen() + 1. · 55d81423
      Rusty Russell authored
      This is least-surprise, but also means callers can sometimes do faster
      string handling by avoiding strstr().

      ccan/tal: always include a length field. · 1651e25e
      Rusty Russell authored
      The current semantics of tal_count() / tal_bytelen() are to return 0
      for anything not allocated using tal_arr*.  This is because we tried
      to save a native-length word in the header, but produces an awkward
      API.
      
      (To make it worse, defining CCAN_TAL_DEBUG turns length to always on,
      and we enable that for c-lightning developer mode, which hides bugs!).
      
      However, for c-lightning, just over half of allocations want a length:
      these use 3 words each, so we're actually worse off overall.
      
      The answer is to always have a length field in the header.  This also
      simplfies the tal code.
      
      samba-allocs stats before:
      Tal time: 1237102-1305755(1.251e+06+/-2.1e+04)ns
      Tal_free time: 1346871-1514514(1.37844e+06+/-5.2e+04)ns
      
      After:
      Tal time: 1115180-1180633(1.1351e+06+/-2.1e+04)ns
      Tal_free time: 1334381-1465933(1.39148e+06+/-4.7e+04)ns

      tal/str and tal/stack: use _label interfaces. · 38ec541c
      Rusty Russell authored
      In particular, tal/str now passes through the label from the caller,
      so (in case of CCAN_TAL_DEBUG) you can actually see the file and line
      where the caller was, not just inside ccan/str.

      tal: add _label interfaces. · ed39cbbd
      Rusty Russell authored
      There are a number of other utilities which use the tal_alloc_ and
      tal_dup_arr_ internal interfaces directly, because they want to set
      the label themselves.  We're about to break them all by changing those
      internal interfaces, so give them a mid-level interface to use.

      tal: rename tal_len to tal_bytelen. · 2cd5e81d
      Rusty Russell authored
      I had a bug caused by using tal_len instead of tal_count: let's make
      it explicit. @jb55 commented "ha. I always forget which one does which... Ack"
