scons python modules malforms additional compiler flags in some cases
Because of following code flags = flags.replace('-Wall', '').replace('-Werror', ''), something like -Werror=format-security becomes =format-security.

Which open source projects use Cbang?
Cbang is used in Camotics and JmpAPI. As indicated at #16 it is not expected to be used in many other projects. Are there any others notable projects using Cbang for which a packaged Cbang in linux repositories may be helpful?
Not all logic CPU threads are reported on Windows.
This should allow 32-bit builds running under WOW64 to see up to 64 cpus.
_WIN32_WINNT is already defined >= 0x0501, so it should be ok.
There has been recent talk about the 32 thread limit for Windows at https://foldingforum.org/viewtopic.php?f=72&t=37736
Option --respawn fails to unset option log
On macOS 10.9+, fahclient is started with --respawn alone, which results in client logs being overwritten by log rotation by the child process. The rotated logs have timestamp in seconds, but respawn takes much less time than that. Result is a rotated logs directory which is mostly uninteresting parent process logs. (Parent rotates previous client log and starts child. Child rotates parent log overwriting previous log.)
Respawn should unset log, just as daemon does.
Need a simple option action ServerApplication::respawnAction, something like
if (!options["child"].toBoolean()
&& options["respawn"].toBoolean())
options["log"].unset();
Undefined references in acmev2Tests and requestTests
acmev2Tests and requestTests fail to build with undefined references.

raise Exception, 'Need library ' + lib
Note the error occurs when compiling core21, not when compiling cbang itself. But it's coming from cbang code, which makes me think something there may have changed that's triggering this.
Websocket support has hard dependency on OpenSSL, ignores with_openssl=no
cbang/src/cbang/event/Websocket.cpp
Line 38 in 8ea7168
As a workaround, websocket support can be disabled with scons disable_local=libevent, which causes the entire event submodule to be disabled.

How to build without included libevent.
Hi. I'm trying to port this over to FreeBSD, and the logical first step would be to use the ported version of libevent - and possibly also bzip2, sqlite3, and zlib - instead of the included one, which simply doesn't build. Any advice how to do this? Thanks!

Versioning of cbang
Joseph,
as I am packaging the cbang as a shared library, I would like you to clarify your policy of cbang versioning so I could properly establish dependency of camotics on cbang library by means of .so version suffix: is the minor version number bumped only for bug fixes and the rest of version number for interface changes?
Thanks,
Sergey
Why package 3rd party libs vs. using their packaged versions?

Scons can't find any library on Fedora
Trying to build cbang on Fedora 25 unsuccessfully under mock environment.
Checking for C library pthread... no
Exception: Need library pthread:
File "/builddir/build/BUILD/cbang-1.0.1/SConstruct", line 47:
conf.CBConfig('compiler')
File "/usr/lib/scons/SCons/SConf.py", line 658:

File "/builddir/build/BUILD/cbang-1.0.1/config/__init__.py", line 111:
raise Exception, 'Need library ' + lib
pthread is present on /usr/lib64/libpthread.so as well as /usr/include/pthread.h, yet it can't find any of those. If I remove the check can't find any other library as well.
By looking at config.log, all issues seems to end with following:
File "/builddir/build/BUILD/cbang-1.0.1/config/compiler/__init__.py", line 20, in __call__
dep.csig = csig
AttributeError: 'File' object has no attribute 'csig'
It looks to me that environment is not set up properly, but I have no idea how to debug this. Any idea on how to look further into this?
Cut a new release
Now that f852996 fixes the SmartPointer bugs, can we cut a 1.5.1 bugfix release that we use for core builds?
Sconstruct version string is inconsistent with published releases
Dear Joseph,
do you consider to tag the current HEAD with a new release as it looks like camotics 1.2.2 is going to be released soon?
Anyway, please update the version string in SCostruct.
Thank you!

Issue discovering freetype
Hello,
I'm very new to cbang and not very familiar with it, but I'm trying to learn to help out with some of the Folding@Home repos that use it.
When building some of those repos (specifically fah-viewer) I ran into an issue with the freetype2 config, here:
cbang/config/freetype2/__init__.py
Line 13 in 3294067
The issue is that libfreetype6 on Ubuntu 19.10 does not install freetype-config anymore. According to this bug using the pkg-config integration is preferable, and has been supported for a long time.
Would you consider this line to use pkg-config? Happy to PR it as well
Use C++ versions of headers
C++ code should import the versions of headers that put everything in the std namespace, for example <cstdio> instead of <stdio.h>. Lots of code in cbang imports the C version instead. For example,
Lines 41 to 45 in 2fb0be7

Boost as shared
I understand that it was complicated for you to check if boost is present on the system automatically so you've removed it 97e5ae8, how about we toggle it with an already present switch disable_local. To build CAMotics without boost all I have to do is following:

Fix detect user idle on linux
Problem is a bug in xscreensaver.
This may not be a problem in recent linux distros.
Anyway, a different mechanism is needed for users who do not use xscreensaver.
A workaround can be found in xprintidle.c
It is GPL 2 only.

Resources rebuilt unncessarily during install or on subsequent builds.
Dear Joseph,
for some reason, the install target triggers rebuild of build/resources.os, which in turn makes the default target out of date.
Could you please change this behavior, so when there is no actual need to rebuild the default target (it was just successfully built), it is not linked again by 'scons install' invocation.

soname policy
Joseph,
I remember that you have no versioning policy in general.
However, in the review response [0] reviewer points that it probably good to have your decision on soname and its versioning. I replied:
As 1) Joseph adds the functionality on as needed basis, 2) there
are obvious bugfixes, 3) camotics builds properly with up-to-date version of cbang
and 4) cbang exports c++ classes, I decided to use `version.subversion` as an so version,
leaving `.revision` for bug fixes in cbang. The leading zero in `libcbang0` is from
upstream, I suspect that it is somehow related to debian packaging/naming, so I
leaved this as is.
So, the idea is to have versioned so name up to subversion number, i.e. libcbang0.so.1.7 presently, to allow bug fixes updates of shared cbang library without the need to rebuild camotics.
Do you have any objections or another vision?
Thank you,
Sergey

cb::SystemUtilites::oopen returns instance of an internal OStream class which crashes on its deletion on Linux
How to reproduce
- Install OpenSSL development libraries (
sudo apt install libssl-devon Debian and Ubuntu) - Checkout the
masterbranch. - Build as usual, then build and run tests:
$ scons
$ cd tests
$ scons
$ ./testHarness --view-failed
- You'll see fails:

It happens only if building cbang in release mode. If being built with scons debug=1, no crash happens. I see this problem on Linux only. When building for Mac, there's no crash regardless of the debug mode.
Do compression methods support multithreading?
Does something need to be enabled to support multithreading with zlib/LZ4/bzip compression? Or are these inherently single- or multi-threaded?

Required version of OpenSSL?
Hello,
In cbang 1.7.0, the configuration script checks that openssl is at least 1.1.0:
Checking for openssl version >= 1.1.0...yes
But src/cbang/openssl/KeyPair.cpp includes openssl/core_names.h which is only available in the devel version of OpenSSL, and also src/cbang/openssl/KeyContext.cpp uses EVP_PKEY_CTX_set1_rsa_keygen_pubexp which is not available in the OpenSSL stable (1.1.1q).
I would rather avoid using the devel version, because it would introduce conflicts with other applications.

Path traversal bug in TarFileReader::extract
Impact:
The latest version bastet-v8.1.16 has a path traversal vulnerability that allows the attacker to create or write to files outside the current directory due to improper string comparisons between canonical paths.
How to reproduce:
wget https://github.com/CauldronDevelopmentLLC/cbang/archive/refs/tags/bastet-v8.1.16.tar.gz
tar -xzf bastet-v8.1.16.tar.gz
cd cbang-bastet-v8.1.16/tests
scons
cd tarTests
# place poc.tar in this directory
./tar --extract poc.tar
# verify attack worked
cat ../tarTests.d/config
Root cause:
cbang/src/cbang/tar/TarFileReader.cpp
Lines 102 to 106 in eae4b58
The root cause is the return true value in function startsWith in String.cpp that passes if condition in function TarFileReader::extract in TarFileReader.cpp.

Extract poc.zip to obtain poc.tar: poc.zip
