Under Ubuntu 18.04, try to compile libraries, above is error information. How to fix it?
Thanks.

To reproduce:

char s[105];
int main()
{
dict *d = dict_new();
read( 0, s, 100 ); // input 100 zeros, i.e., '00000000'...
dict_del( d, s ); // successful, now d->used==-1
return 0;
}

By the way, dict_free(d) doesn't check if dict is valid, may lead to heap crash.
To reproduce:

int main()
{
dict *d = dict_new();
dict_free( d );
dict_free( d ); // heap crash
return 0;
}

我在 windows10 用 x86_64-w64-mingw32 编译这个库的时候，libposix 这个库一直没编译通过，主要是 libposix4win.h 这个头文件依赖 MsvcLibX 这个库的 msvclibx.h 这个头文件。但是这个库是是专为微软的 vc++ 使用的，这就造成了一个问题，我无法使用 windows下的x86_64-w64-mingw32-gcc 编译器编译通过。所以想求助一下，怎样让 x86_64-w64-mingw32-gcc 正常编译通过 libposix 库。

Hey there!

I belong to an open source security research community, and a member (@geeknik) has found an issue, but doesn’t know the best way to disclose it.

If not a hassle, might you kindly add a SECURITY.md file with an email, or another contact method? GitHub recommends this best practice to ensure security issues are responsibly disclosed, and it would serve as a simple instruction for security researchers in the future.

Thank you for your consideration, and I look forward to hearing from you!

现在设计一个内存池确实有些显得蛋疼，要是不用C语言，语言已经简化到不用关心内存是在堆内存还是在栈内存上了，内存管理算法这种高级货真是只为情怀而来

http://git.videolan.org/gitweb.cgi/vlc.git/?p=vlc.git;a=blob_plain;f=modules/demux/mp4/libmp4.c;hb=HEAD

libmp4.c is licensed under LGPL, which is incompatible with MIT license.

这里获取到的数值全部都是0，是不是应该使用*len = it->opaque.iov_len;

谢谢

Hi, nice work you have done here!

GPL v2 is somewhat problematic. It cannot be linked against GPLv3 code: http://gplv3.fsf.org/dd3-faq

I suggest to either release this as GPLv2+, or LGPL. LGPL is more appropriate for a library.

这里实现得不是十分简洁，回头有空了想简单重构下。

目前的Makefile/Android.mk/Makefile.nmake内容都是按debug模式编译输出。没有计划提供release模式？
由于涉及全部内容模块，我没有在版本中修改，每次使用都需要手工提换Makefile，你这边有没有统一修改计划？
我修改内容如下，可作参考
Linux debug版：
使用现在Makefile
release版
去除-g 添加,-O2后-Os，模块编译完毕添加strip

Android debug版：
使用现在Android.mk
release版
添加LOCAL_STRIP_MODULE=ture，LOCAL_CFLAGS += -O2

windows Debug 版本：
使用现在Makefile.nmake
Release 版本：
CFLAGS = $(CFLAGS) /Od /W3 /Zi
修改为
CFLAGS = $(CFLAGS) /O2 /GF

你好，我在您liblog.c 的get_proc_name 函数中，觉得有两处地方不妥，您看看是否正确

line 191 原 proc = (char *)calloc(1, i); 应改为 proc = (char *)calloc(1, ret - i);
line 193 原 strncpy(proc, ptr, i); 应改为 strncpy(proc, ptr, ret - i);

测试场景：(当proc_name 长度大于 路径长度时，原有代码功能就不对了。)
example： /home/proc_name_test.out

librtmp发送h264数据到nginx-rtmp无法播放，
const char *url = "rtmp://127.0.0.1:1935/live/test";
rtmp = rtmp_create(url);
rtmp_stream_start(rtmp);
int ret = rtmp_stream_add(rtmp, RTMP_DATA_H264, &h264_data); 这个是需要什么时候调用
live555 出来的数据直接发送到
rtmp_send_data(rtmp, RTMP_DATA_H264, (uint8_t *)data, h264_data.iov_len, 0);
示例代码比较少，不知道哪儿有问题，还是h264裸数据流需要特殊处理下，谢谢大神！

./build.sh libp2p

libp2p库是没有维护了吗？

问题描述：

1. git clone拿到代码编译运行，会报一系列的编译错误。
2. 这些错误的原因都是因为有开源库的依赖，比如lua.h 找不到，x264的库找不到
   这些在INSTALL.md里面都找不到说明，有以下两点建议：
   a. 在install.md 说明相关依赖
   b. install.md 里面新增单个模块的编译指令的说明，build.sh 也支持单个模块编译的方法（看了下build.sh 找到单独编译的指令啦）

need some example, such as librtsp libp2p libuvc

liblock.c line 237 and 238 in the mutex_cond_wait() function:

ts.tv_sec += ms / 1000;
ts.tv_nsec += (ms % 1000) * 1000000;

But personally , I think it should be :

struct timespec now;
ts.tv_sec = now.tv_sec + ms / 1000 + ( now.tv_nsec + (ms % 1000) * 1000000 ) / (1000_1000_1000);

ts.tv_nsec = ( now.tv_nsec + (ms % 1000) * 1000000 ) % (1000 * 1000 *1000);

example：
ts.tv_sec = 0 ts.tv_nsec = 999 000 000 ms = 2

then after calculate, the right time should be :
ts.tv_sec = 1 ts.tv_nsec = 001 000 000
but you code will calculate the time will be wrong .

The same as line 507, in function sem_lock_wait()

I find that include guards like "LIBTIME_H" and "QUEUE_H" are too short for the safe reuse of your header files (when they belong to an application programming interface).

issue test

hisi cross platform compile error ,
modify build.sh pi config to CROSS_PREFIX=aarch64-himix100-linux-
use ./build.sh all pi release
and i got this error :

another problem is i use run objdump -d libbase64.so
it show libbase64.so： elf64-x86-64, not elf64-little

thansk.

下的release压缩包 直接解压build

这个头文件是有的 怎么还是提示缺少 路径也已经包含进去了
而且我在build all 的时候 会出现各种错误

这是gcc版本

hello , I have reviewed the liblog.c and I personally think that the _log_write() function could be optimized.
your code are bellow:(from line 382)
log_get_time(_log_name_time, sizeof(_log_name_time), 1);
snprintf(_log_name, sizeof(log_name), "%s%s%s",
_log_path, _log_name_prefix, _log_name_time);
_log_open(_log_name);
fprintf(stderr, "splited file %s\n", _log_name);

but I think they can may be:
log_get_time(_log_name_time, sizeof(log_name_time), 1);
char log_rename[FILENAME_LEN];
snprintf(log_rename, sizeof(log_rename), "%s%s%s",
_log_path, _log_name_prefix, _log_name_time);
int ret = rename(_log_name,log_rename );
if (ret == -1)
{
fprintf(stderr, "log file splited rename error:%s\n",log_rename );
}
_log_open(_log_name);

In the real production environment, maybe we want to splite the log file to a new renamed file,and connitue to write on the file with old name. So in the code , I suggest to add a rename() function.
Of course, it's all up to you decide.

My English is limited ,if any question , you can contact me [email protected], thanks!

现象表明TIMER_PERSIST定时器未生效。是否表明此处存在一个bug？或者是我哪些步骤存在问题导致的？我需要怎么验证找出问题出在哪里？

对了，我是修改了build.sh加了自己的编译工具链，编译出来的arm可执行文件的。

gear-lib is a library for IOT, and force on network protocol, multi-media stream,
please write down the feature list you want to use on this issue.
I will plan to achieve them.

gear-lib作为IOT的库，偏向于底层+网络协议+流媒体方向
作为使用者的你，希望新加入什么样的feature，请在该issue下畅所欲言
我会按计划逐步丰富该库

当数据写到buffer尾部时，如果队尾如果在写数据有问题

0.项目起源:
最初是2014年，在工作中幸运的经历过从bootloader到linux到filesystem到media stream到android app到web server的整个开发流程，使用过许多开源代码，也造过许多丑陋的轮子．
　项目虽然早已结束，但回头看发现很多值得沉淀的东西，因此闲暇之余就想整理出来，最初想法只是为方便自己快速开发．作为小白码农，从liblog开始了第一个尝试．如果当时看到别人写的大而全的C库，很可能会因为珠玉在前就放弃坚持了，所幸发现这类库总会有各种用的不爽的地方．
　申明下，该项目不涉及公司代码，遵循POSIX/UNIX的原则，尽量做到小而完备．

1.项目定位:
　该库的定位是能基本满足IOT嵌入式/网络服务/流媒体等场景的开发，不再需要从POSIX的底层API写起，可以节省精力做业务逻辑．
　完全使用C代码开发，原因是我不会C++，汗颜．．．
　对于大部分公司，一般都会有自己完备的基础库，而且对License非常谨慎．因此该库主要面向开源群体或小团队等．

2.项目协作开发:
　如果是新手，可以先从Data Struct部分开始，再复杂庞大的项目，其骨干代码的基本**也是由基本算法数据结构实现的．
　如果是网络服务开发者，可以从Network和Async部分开始，IPC/RPC是绕不开的一环．
　如果是多媒体开发者，可以从MultiMedia部分开始，或者进入到另一个项目aquila
　如果你是高手，欢迎指正．

However in ac44a17 the LICENSE.LGPL was removed.

In the libvector directory, there is an error in line 66 in the test example and a function may need to be added with the vector_end modification of line 69 of libvector.h

I would like to point out that identifiers like "_LIBDEBUG_H_" and "_LIBLIGHTLIB_H_" do eventually not fit to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?
