phase1: use wrappers for ccache

750174c0cee95925dd322f37c211577d0ebc0dc4 attempted to inject ccache
into the CC environment, but that doesn't work as the CC/CXX variables
are processed by the build system, in order to extract the path to an
executable file.

This commit works around that situation by creating two simple wrapper
scripts on the slave. The remaining logic is unchanged:

When tryccache is False, CC/CXX point to the regular compilers and no
ccache injection is performed.

When tryccache is True, CC/CXX point to their respective wrapper, and
CCACHE is set to the path to ccache (if it exists, empty otherwise),
CCC/CCXX point to the original compilers, and the wrappers will execute
'${CCACHE} ${CCC} "$@"' or '${CCACHE} ${CCXX} "$@"'. If ${CCACHE} is
unset, this falls back to plain compilers.

i.e. ccache is only used if tryccache=True AND ccache has been found on
the slave.

Use 'exec' to avoid lingering shell during execution.

This patch uses sha2rsync.pl to build a list of files to upload
to the remote server via rsync.

Because --files-from is taken as a literal list of files to consider by
rsync (the file list generation is skipped), it will not delete files on
the receiver.

queue management system, 'targetupload' is split in two: the first step
uploads and updates new and existing files using rsync standard
mechanism, and the second step does nothing but delete files that are
present on the receiver but not on the sender.

6 years agophase1: don't enable rsync compression where unnecessary
Thibaut VARÈNE [Thu, 21 Jun 2018 11:51:26 +0000 (13:51 +0200)]
phase1: don't enable rsync compression where unnecessary

Enabling rsync compression for already compressed files adds CPU
and memory overhead that negatively impacts upload speed on data
that cannot be further compressed.

By default rsync ignores '-z' on a number of files it knows to be
already compressed (based on filename suffix), but the list is not
exhaustive and doesn't include e.g. '.ipk'. Instead of trying to maintain
a list of all known compressed suffixes uploaded by the build system,
it's simpler and less error prone to simply disable the option for
specific steps where all or nearly all of the transferred files are known
to be already compressed.

6 years agophase1: reduce verbosity of rsync
Thibaut VARÈNE [Wed, 20 Jun 2018 18:37:59 +0000 (20:37 +0200)]
phase1: reduce verbosity of rsync

The purpose of this patch is to reduce uplink bandwidth contention when
rsync uploads are running.

This patch:
- replaces '-v' and '--progress' by '--info=name' in rsync's parameter
  list (assuming it's necessary to output a list of updated files)
- introduces a wrapper script 'rsync.sh' which checks for the presence
  and executability of 'pv' and pipes the output of rsync through
  'pv -t -i 60 -f' if possible, and falls back to plain rsync otherwise.

'--info=name' prints one line to stdout for each file that is updated on
the remote side.
'pv -t -i 60 -f' prints a 1mn-resolution timer to stderr, with the goal
of preventing the current buildbot step to timeout due to lack of process
output.

It's worth noting that '--progress' did not prevent some timeouts (most
notably on the 'sourceupload' step) since --progress only emits output
for files that are updated on the remote side.

6 years agophase1: rsync: use --size-only instead of --checksum
Thibaut VARÈNE [Wed, 20 Jun 2018 15:36:02 +0000 (17:36 +0200)]
phase1: rsync: use --size-only instead of --checksum

'--checksum' puts heavy I/O and memory load on both the sender and the
receiver and dramatically reduces rsync's speedup. Furthermore, if
multiple slaves are uploading at once the receiver may become overloaded,
slowing down the whole build farm. From rsync manpage:
    Generating the checksums means that both sides will expend a lot of
    disk I/O reading all the data in the files in the transfer (and this
    is prior to any reading that will be done to transfer changed files),
    so this can slow things down significantly.
This slowdown causes timeouts for some build slaves, noticeably in the
'sourceupload' step.

'--size-only' matches files by size only. Compared to '--checksum', it is
faster, and does not aggravate the collision/error risk (if two files of
the same name and size have different checksums, we don't have a heuristic
to determine which is "correct" and which is "invalid" anyway)

6 years agophase1: provide upload/download locking
Thibaut VARÈNE [Thu, 7 Jun 2018 17:12:38 +0000 (19:12 +0200)]
phase1: provide upload/download locking

This patch offers an optional locking mechanism to ensure that specific
build slaves do not perform concurrent network operations

Each slave definition can feature two additional options:

ul_lock = <lock identifier string>
dl_lock = <lock identifier string>

In the scenario where a group of build slaves share the same physical
network link, these variables can be used as follows:

If the link is full duplex capable, each slave from the target group
would be configured with e.g.:

dl_lock = slavegroup1_dl
ul_lock = slavegroup1_ul

This enables separate locks for uplink and downlink.

If the link is not full duplex capable, then each slave from the target
group would be configured with e.g.:

dl_lock = slavegroup1
ul_lock = slavegroup1

Effectively making uplink and downlink share the same lock

If neither option is set, no lock is enforced and the patch is a no-op.

In this patch the locks are only applied to steps that cause significant
network traffic.
