My misunderstanding of OpenLDAP API

• Development

I used to think that ldap_unbind() is the opposite of ldap_bind(), however I was wrong. Pierangelo Masarati (ando at openldap) pointed out that it was actually opposite of ldap_init(). So, do NOT expect init() -> bind() -> search() -> unbind() -> bind() would success, it’s simply wrong thing. You do not need to unbind() before you do another bind().

Just make a note.

漏啊,漏啊

• Development

今天给某个维护OpenLDAP相关port的老大提了几个patch,等他消息了。

另外就是Python自己也会有泄漏,而且居然是gc部分自己出了许多tuple,这年头:(

FreeBSD src Makefile大手术

• Development

Ruslan Ermilov大长辈commit了一组Makefile变动。这包含了许多来自NetBSD和FreeBSD ports的特性。

  • 新增了MK_*选项。这些选项是开发人员设置的,如果用户配置的话将发生错误。
  • 使用WITH_*和WITHOUT_*来控制是否build选项。
  • 某些选项提供了MK_*_SUPPORT子选项。
  • 系统选项可以在 /etc/src.conf 来配置。

感觉比之前要清晰许多。

OpenLDAP的内存泄漏

• Development

今天发现了OpenLDAP client库的一个内存泄漏(每次连接会漏掉大约80字节),并提交了ITS patch(4441),不过我觉得这里面上锁上的还是有点问题的,至少逻辑不是很清楚。

while(0)是干吗的?

• Development

今天 renzhen 同学问起为什么很多宏都定义为 do { something… } while(0),我也顺便温习了一下。

简而言之:如果希望宏表现的和函数接近,就需要这样做。

给csh增加了简体中文(GBK)支持

• Development

对GBK的locale做了一些改动,使得其能够提供正确的字符宽度信息了。这样一来,csh就能够正确处理GBK的中文了。昨天还增加了正体(我们叫做繁体)中文对应的locale变化。

bsd.port.mk: critical issue for RELENG_6

• Development

Today I have submitted a PR which I have marked “critical”. bsd.port.mk does not do the right thing on RELENG_6 after the rcorder change, which will cause all ports installed rc.d scripts stop to function at system startup.

The PR can be accessed here: https://www.freebsd.org/cgi/query-pr.cgi?pr=93536

UPDATE(20060219): It seems that the problem is not related to this. I am still investigating what was happening.

UPDATE(20060220): Doug Barton has kindly provided information about the issue. It was because some nojail and mountcritlocal conflict. The issue can only appear when you are using jail(8).
