* [build] Add version files to docker image dependencies
* [ci] Support to skip vstest using include/exclude config file. (#11086)
example:
├── folderA
│ ├── fileA (skip vstest)
│ ├── fileB
│ └── fileC
If we want to skip vstest when changing /folderA/fileA, and not skip vstest when changing fileB or fileC.
vstest-include:
^folderA/fileA
vstest-exclude:
^folderA
In Makefile.cache, for $(1)_DEP_PKGS_SHA, the intention is to include
the DEP_MOD_SHA and MOD_HASH of each of the current package's
dependencies. However, there's a level of dereferencing missing; instead
of grabbing the value of $(dfile)_DEP_MOD_SHA, it is literally using the
variable name $(dfile)_DEP_MOD_SHA. This means that the value of this
variable will not change when some dependency changes.
The impact of this is in transitive dependencies. For a specific
example, if there is some change in sairedis, then sairedis will be
rebuilt (because there's a change within that component), and swss will
be rebuilt (because it's a direct dependency), but
docker-swss-layer-buster will not get rebuilt, because only the direct
dependencies are effectively being checked, and those aren't changing.

#### Why I did it
Fixed an issue that changing SDK version leads to cache framework taking cached syncd RPC image rather then rebuilding syncd RPC based on new syncd with new SDK.
Investigation showed that cache framework calculates a component hash based on direct dependencies. Syncd RPC image hash consists of two parts: one is the flags of syncd RPC (platform, ENABLE_SYNCD_RPC) and syncd RPC direct dependencies makefiles. None of the syncd RPC direct dependencies are modified when SDK version changes, so hash is unchanged.
#### How I did it
To fix this issue, include the hash of dependencies into current component hash calculation, e.g.:
In calcultation of the hash ```docker-syncd-mlnx-rpc.gz-274dfed3f52f2effa9989fc-39344350436f9b06d28b470.tgz```, the hash of syncd is included: ```docker-syncd-mlnx.gz-48ee88ac54b201e0e107b15-7bbea320025177a2121e440.tgz``` in which the hash of SDK is included.
#### How to verify it
Build with cache enabled and check that changing SDK version leads to a different hash of syncd rpc image:
SDK version 4.5.1002:
```
docker-syncd-mlnx.gz-48ee88ac54b201e0e107b15-7bbea320025177a2121e440.tgz
docker-syncd-mlnx-rpc.gz-274dfed3f52f2effa9989fc-39344350436f9b06d28b470.tgz
```
SDK version 4.5.1002-005:
```
docker-syncd-mlnx.gz-18baf952e3e0eda7cda7c3c-e5668f4784390d5dffd55af.tgz
docker-syncd-mlnx-rpc.gz-4a6e59580eda110b5709449-552f76be135deaf750aeab2.tgz
```
for exmaple, for arm64, the sonic-slave docker image name
is sonic-slave-arm64-$(USER)
for amd64, the docker image is kept as it is

Fix#5692
It fixes the folling error when DPKG cache enabled.
make: execvp: /bin/bash: Argument list too long
make: *** [slave.mk:389: target/debs/buster/sonic-device-data_1.0-1_all.deb] Error 127
- Why I did it
Number of dependent file list is more than 2K which causes bash arg long error.
- How I did it
Used file operation to store the dependency list.
- Fixes the dependency issue in the DPKG dependent SHA calculation.
- The dependent SHA value of package is derived from the content of all its dependent packages.
SHA_HASH => is an SHA value derived from a module/package dedpendent files ( .flags, .sha and .smsha files) .
SHA_VALUE = > is an SHA value derived from a module/package dependent packages(.deb, .whl, etc)
Eg, For SNMP docker, SNMP and SNMPD packages are the dependency
$(DOCKER_SNMP)_DEPENDS += $(SNMP) $(SNMPD)
So, the SHA value calculation of SNMP would include the SHA value of SNMP and SNMPD packages as well. so that any change in the package should trigger the docker rebuild.
Most of the devs know how they configured their build.
Instead of generating a huge header for every make operation, allow the
user to silence it via an environment variable.
SONIC_BUILD_QUIETER=y make ...
Also add SONIC_BUILDER_EXTRA_ENV variable which allows the user to
inject arbitrary options to the docker run cmdline for the builder.
SONIC_BUILDER_EXTRA_CMDLINE="-e test=var -e var='with spaces'" make ...
[baseimage]: upgrade base image to debian buster
bring up the base image to debian buster 4.19 kernel.
using the merge commits to preserve the individual commits to better track the history.
add $(BLDENV) in cache flags for following targets:
- $(SONIC_MAKE_DEBS)
- $(SONIC_DPKG_DEBS)
- $(SONIC_ONLINE_DEBS)
- $(SONIC_COPY_DEBS)
- $(SONIC_MAKE_FILES)
This is because we could build a same package for both
base image and docker which can be different os distribution,
i.e., buster v.s. stretch.

DPKG caching framework provides the infrastructure to cache the sonic module/target .deb files into a local cache by tracking the target dependency files.SONIC build infrastructure is designed as a plugin framework where any new source code can be easily integrated into sonic as a module and that generates output as a .deb file. The source code compilation of a module is completely independent of other modules compilation. Inter module dependency is resolved through build artifacts like header files, libraries, and binaries in the form of Debian packages. For example module A depends on module B. While module A is being built, it uses B's .deb file to install it in the build docker.
The DPKG caching framework provides an infrastructure that caches a module's deb package and restores it back to the build directory if its dependency files are not modified. When a module is compiled for the first time, the generated deb package is stored at the DPKG cache location. On the subsequent build, first, it checks the module dependency file modification. If none of the dependent files is changed, it copies the deb package from the cache location, otherwise, it goes for local compilation and generates the deb package. The modified files should be checked-in to get the newer cache deb package.
This provides a huge improvement in build time and also supports the true incremental build by tracking the dependency files.
- How I did it
It takes two global arguments to enable the DPKG caching, the first one indicates the caching method and the second one describes the location of the cache.
SONIC_DPKG_CACHE_METHOD=cache
SONIC_DPKG_CACHE_SOURCE=
where SONIC_DPKG_CACHE_METHOD - Default method is 'cache' for deb package caching
none: no caching
cache: cache from local directory
Dependency file tracking:
Dependency files are tracked for each target in two levels.
1. Common make infrastructure files - rules/config, rules/functions, slave.mk etc.
2. Per module files - files which are specific to modules, Makefile, debian/rules, patch files, etc.
For example: dependency files for Linux Kernel - src/sonic-linux-kernel,
SPATH := $($(LINUX_HEADERS_COMMON)_SRC_PATH)
DEP_FILES := $(SONIC_COMMON_FILES_LIST) rules/linux-kernel.mk rules/linux-kernel.dep
DEP_FILES += $(SONIC_COMMON_BASE_FILES_LIST)
SMDEP_FILES := $(addprefix $(SPATH)/,$(shell cd $(SPATH) && git ls-files))
DEP_FLAGS := $(SONIC_COMMON_FLAGS_LIST) \
$(KERNEL_PROCURE_METHOD) $(KERNEL_CACHE_PATH)
$(LINUX_HEADERS_COMMON)_CACHE_MODE := GIT_CONTENT_SHA
$(LINUX_HEADERS_COMMON)_DEP_FLAGS := $(DEP_FLAGS)
$(LINUX_HEADERS_COMMON)_DEP_FILES := $(DEP_FILES)
$(LINUX_HEADERS_COMMON)_SMDEP_FILES := $(SMDEP_FILES)
$(LINUX_HEADERS_COMMON)_SMDEP_PATHS := $(SPATH)
Cache file tracking:
The Cache file is a compressed TAR ball of a module's target DEB file and its derived-target DEB files.
The cache filename is formed with the following format
FORMAT:
<module deb filename>.<24 byte of DEP SHA hash >-<24 byte of MOD SHA hash>.tgz
Eg:
linux-headers-4.9.0-9-2-common_4.9.168-1+deb9u3_all.deb-23658712fd21bb776fa16f47-c0b63ef593d4a32643bca228.tgz
< 24-byte DEP SHA value > - the SHA value is derived from all the dependent packages.
< 24-byte MOD SHA value > - the SHA value is derived from either of the following.
GIT_COMMIT_SHA - SHA value of the last git commit ID if it is a submodule
GIT_CONTENT_SHA - SHA value is generated from the content of the target dependency files.
Target Specific rules:
Caching can be enabled/disabled on a global level and also on the per-target level.
$(addprefix $(DEBS_PATH)/, $(SONIC_DPKG_DEBS)) : $(DEBS_PATH)/% : .platform $$(addsuffix -install,$$(addprefix $(DEBS_PATH)/,$$($$*_DEPENDS))) \
$(call dpkg_depend,$(DEBS_PATH)/%.dep )
$(HEADER)
# Load the target deb from DPKG cache
$(call LOAD_CACHE,$*,$@)
# Skip building the target if it is already loaded from cache
if [ -z '$($*_CACHE_LOADED)' ] ; then
.....
# Rules for Generating the target DEB file.
.....
# Save the target deb into DPKG cache
$(call SAVE_CACHE,$*,$@)
fi
$(FOOTER)
The make rule-'$(call dpkg_depend,$(DEBS_PATH)/%.dep )' checks for target dependency file modification. If it is newer than the target, it will go for re-generation of that target.
Two main macros 'LOAD_CACHE' and 'SAVE_CACHE' are used for loading and storing the cache contents.
The 'LOAD_CACHE' macro is used to load the cache file from cache storage and extracts them into the target folder. It is done only if target dependency files are not modified by checking the GIT file status, otherwise, cache loading is skipped and full compilation is performed.
It also updates the target-specific variable to indicate the cache is loaded or not.
The 'SAVE_CACHE' macro generates the compressed tarball of the cache file and saves them into cache storage. Saving into the cache storage is protected with a lock.
- How to verify it
The caching functionality is verified by enabling it in Linux kernel submodule.
It uses the cache directory as 'target/cache' where Linux cache file gets stored on the first-time build and it is picked from the cache location during the subsequent clean build.
- Description for the changelog
The DPKG caching framework provides the infrastructure to save the module-specific deb file to be cached by tracking the module's dependency files.
If the module's dependency files are not changed, it restores the module deb files from the cache storage.
