问题
自从开始使用debian11，应该是subversion版本的升级，导致不可以存储明文的密码，导致每次都要输入密码，很恼人。
Debian版本
➜ .gnupg lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye
➜ .gnupg
Debian11的svn版本如下
➜ .gnupg svn --version
svn, version 1.14.1 (r1886195)

Subversion is open source software, see http://subversion.apache.org/The following repository access (RA) modules are available:* ra_svn : Module for accessing a repository using the svn network protocol.
- with Cyrus SASL authentication
- handles 'svn' scheme
* ra_local : Module for accessing a repository on local disk.
- handles 'file' scheme
* ra_serf : Module for accessing a repository via WebDAV protocol using serf.
- using serf 1.3.9 (compiled with 1.3.9)
- handles 'http' scheme
- handles 'https' schemeThe following authentication credential caches are available:* Gnome Keyring
* GPG-Agent
* KWallet (KDE)➜ .gnupgsvn config
svn支持对每个用户使用不同的配置，于是相应的配置在如下目录:
$HOME/.subversion
~/.subversion/config
[auth]
### Set password stores used by Subversion. They should be
### delimited by spaces or commas. The order of values determines
### the order in which password stores are used.
### Valid password stores:
### gnome-keyring (Unix-like systems)
### kwallet (Unix-like systems)
### gpg-agent (Unix-like systems)
### keychain (Mac OS X)
### windows-cryptoapi (Windows)
# password-stores = gpg-agent,gnome-keyring,kwallet
### To disable all password stores, use an empty list:
# password-stores =
gpg-agent
新版本的svn默认支持gpg-agent，那么问题演变成配置这个工具。
添加下边两个环境变量到 ~/.zshrc 或者 ~/.bashrc，依据使用的shell类型
export GPG_TTY=$(tty)
export GPG_AGENT_INFO=`gpgconf --list-dirs agent-socket | tr -d '\n' && echo -n ::`
svn会缓冲auth的东西到~/.subversion/auth，为了使用gpg-agent，将老的东西删除
rm -rf ~/.subversion/auth
然后是当前的配置生效
source ~/.zshrc
当第一次登录svn需要输入密码，之后密码会cache住直到失效，可以更改其配置。
gpg-agent.conf
gpg-agent本身有配置，可以配置密码失效时间这个文件在
~/.gnupg/gpg-agent.conf
- default-cache-ttl默认密码失效时间是600s，每次重新访问svn，就会将计时器重置。
意味着如果600s之内有svn访问记录，那么就不用再次输入密码，如果超过600s没有使用svn，就需要重新输入密码 - max-cache-ttl默认最大有效时间是7200s，不管上边的是不是在600s之内重新使用过svn，到两个小时之后都需要重新输入密码。
下边可以重新设置参数，当然还有其他参数，设置完成之后要重新启动gpg-agent。
gpg-connect-agent reloadagent /bye
